-

-	* docs/CHANGES: Updating for 2.0.8.

-

-	* include/freetype/freetype.h: Setting `PATCH_LEVEL' to 8 and

-	removing `FT_Get_Next_Char' from the API (temporarily).

-

-	* include/freetype/freetype.h: Adding comments to FT_Get_Next_Char;

-	the AVERAGE_WIDTH property.

-

-2002-02-06  David Turner  <[email protected]>

-

-	* src/sfnt/sfobjs.c (SFNT_Load_Face): Since many fonts embedded in

-	error if these are not present.

-

-	Note that the specification _requires_ these tables, but Adobe

-	seems to ignore it completely.

-

-	* src/sfnt/ttcmap.c: Removing compiler warnings.

-

-	src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c,

-	src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler

-

-2002-01-05  David Turner  <[email protected]>

-

-	* src/autohint/ahhint.c (ah_align_linked_edge): Modified computation

-	of auto-hinted stem widths; this avoids color fringes in

-	`ClearType-like' rendering.

-

-	* src/truetype/ttgload.c (TT_Load_Glyph_Header,

-	TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph):

-	Modified the TrueType loader to make it more paranoid; this avoids

-	nasty buffer overflows in the case of invalid glyph data (as

-

-2002-01-04  David Turner  <[email protected]>

-

-	* README.UNX: Added special README file for Unix users.

-

-	* builds/unix/ftsystem.c (FT_New_Stream): Fixed typo.

-

-2002-01-03  Keith Packard  <[email protected]>

-

-	* builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that

-	all FreeType input streams are closed in child processes of a `fork'

-	on Unix systems.  This is important to avoid (potential) access

-	control issues.

-

-2002-01-03  David Turner  <[email protected]>

-

-	* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the

-	library when dealing with certain weird fonts like `Stalingrad', in

-	`sadn.pfb' (this font has no full font name entry).

-

-	* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):

-	New function to check the consistency of outline data.

-

-	* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to

-	ensure that loaded glyphs are valid.  This allows certain fonts like

-	`tt1095m_.ttf' to be loaded even though it appears they contain

-	really funky glyphs.

-

-	There still is a bug there, though.

-

-	* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.

-

-2001-12-30  David Turner  <[email protected]>

-

-	* src/autohint/ahhint.c (ah_hinter_load): Fix advance width

-	computation of auto-hinted glyphs.  This noticeably improves the

-	spacing of letters in KDE and Gnome.

-

-2001-12-25  Antoine Leca  <[email protected]>

-

-	* builds/dos/detect.mk: Correcting the order for Borland compilers:

-	16-bit bcc was never selected, always overridden by 32-bit bcc32.

-

-2001-12-22  Francesco Zappa Nardelli  <[email protected]>

-

-	* src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'

-	and fix incorrect computation of `available_sizes'.

-

-2001-12-22  David Turner  <[email protected]>

-

-	* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an

-	incorrect glyph advance in the case of mono-width fonts (like

-	Courier, Andale Mono, and others).

-

-2001-12-22  Detlef Würkner  <[email protected]>

-

-	* builds/amiga/*: Adaptations to latest changes.

-	Support added for MorphOS.

-

-2001-12-22  Werner Lemberg  <[email protected]>

-

-	* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.

-	(ps_mask_table_merge, ps_hints_open, ps_hints_stem,

-	ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix

-	FT_ERROR messages.

-	* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as

-	`trace_pshalgo1'.

-	`trace_pshalgo2'.

-	* include/freetype/internal/ftdebug.h (FT_Trace): Updated.

-

-	* docs/modules.txt: New file.

-

-2001-12-21  David Turner  <[email protected]>

-

-	* src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):

-	Ignore invalid `hintmask' and `cntrmask' operators (instead of

-	returning an error).  Glyph 2028 of the CFF font `MSung-Light-Acro'

-	couldn't be rendered otherwise (it seems its charstring is buggy,

-	though this requires more analysis).

-	(FT_COMPONENT): Define.

-

-	* src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c

-	(T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a

-	bug where the X and Y axis where inverted in the postscript hinter.

-	This caused problem when displaying on non-square surfaces.

-

-	* src/pshinter/pshalgo2.c: s/vertical/dimension/.

-

-	* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating

-	point constant with a fixed-float equivalent.  For some reasons not

-	all compilers are capable of directly computing a floating pointer

-	constant casted to FT_Fixed, and will link a math library instead.

-

-2001-12-20  Werner Lemberg  <[email protected]>

-

-	* src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix

-	tracing strings.

-

-	* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated

-	to move the definition of encoding tables back within `cffload.c'

-

-	* docs/FTL.TXT: Simple fix (change `LICENSE.TXT' to `FTL.TXT').

-

-	* builds/unix/freetype2.m4: New file for checking configure paths.

-	We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I

-	didn't modify builds/unix/install.mk yet.

-

-	* INSTALL: Updated the instructions to build shared libraries with

-	Jam.  They were simply wrong.

-

-	* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused

-	slightly improper results for `FT_Cos' and `FT_Sin' (example:

-	FT_Sin(0) == -1!).

-

-2001-12-11  Detlef Würkner  <[email protected]>

-

-	* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):

-	Fixed incorrect argument types.

-	of certain fonts) and the cache system.

-

-	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.

-	* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.

-	src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler

-	warnings.

-

-	* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:

-	Yet another massive rewrite of the caching sub-system in order to

-	both increase performance and allow simpler cache sub-classing.  As

-	simpler.

-

-	I still need to update the documentation in

-	www/freetype2/docs/cache.html to reflect the new design though.

-

-	* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New

-	macro.

-	(FT_CACHE_INTERNAL_CACHE_H): Updated.

-

-2001-12-05  David Krause  <[email protected]>

-2001-11-20  Antoine Leca  <[email protected]>

-

-	* include/freetype/ttnameid.h: Added some new Microsoft language

-	codes and LCIDs as found in MSDN (Passport SDK).  Also added

-	comments about the meaning of bit 57 of the `OS/2' table

-	(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is

-	a character beyond 0xFFFF in this font'.  Thanks to Detlef Würkner

-	<[email protected]> for noticing this.

-

-2001-11-20  David Turner  <[email protected]>

-

-	* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting

-	routine that created nasty alignment artefacts.

-

-	* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.

-

-	* src/smooth/ftgrays.c: De-activated experimental gamma support.

-	Apparently, `optimal' gamma tables depend on the monitor type,

-	resolution and general karma, so it's better to compute them outside

-	of the rasterizer itself.

-	(gray_convert_glyph): Use `volatile' keyword.

-

-2001-10-29  David Turner  <[email protected]>

-

-	Adding experimental `gamma' support.  This produces smoother glyphs

-	at small sizes for very little cost.

-

-	* src/smooth/ftgrays.c (grays_init_gamma): New function.

-	(gray_raster_new): Use it.

-

-	Various fixes to the auto-hinter.  They merely improve the output of

-	sans-serif fonts.  Note that there are still problems with serifed

-	fonts and composites (accented characters).

-

-	* src/autohint/ahglyph.c (ah_outline_load,

-	ah_outline_link_segments): Implement it.

-	Fix typos.

-	(ah_outline_save, ah_outline_compute_segments): Fix typos.

-	* src/autohint/ahhint.c (ah_align_serif_edge): New argument

-	(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'

-	(making them global as `ah_debug_disable_horz' and

-	`ah_debug_disable_vert').

-	Fix typos.

-

-	* tests/gview.c: Updated the debugging glyph viewer to show the

-	hints generated by the `autohint' module.

-

-2001-10-27  David Turner  <[email protected]>

-

-	* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that

-	considerably lowered the performance of the abstract chunk cache.

-

-2001-10-26  David Turner  <[email protected]>

-

-	* include/freetype/ftcache.h, include/freetype/cache/*.h,

-	src/cache/*.c: Major re-design of the cache sub-system to provide

-	better performance as well as an `Acquire'/`Release' API.  Seems to

-	work well here, but probably needs a bit more testing.

-

-2001-10-26  Leonard Rosenthol  <[email protected]>

-

-	* builds/mac/README: Updated to reflect my taking over the project

-	and that is now being actively maintained.

-

-	* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller

-	<[email protected]> to support loading a face other than the

-	first from a FOND resource.

-	(FT_New_Face_From_FOND): Updated.

-

-2001-10-25  Leonard Rosenthol  <[email protected]>

-

-	* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac

-	OS for latest version (7) of CWPro and for recent changes to the FT

-	source tree.

-

-2001-10-25  David Turner  <[email protected]>

-

-	* include/freetype/config/ftoption.h: Updated comments to explain

-	precisely how to use project-specific macro definitions without

-	modifying this file manually.

-

-	(FT_CONFIG_FORCE_INT64): Define.

-

-	(FT_DEBUG_MEMORY): New macro.

-

-2001-10-24  Tom Kacvinsky  <[email protected]>

-

-	* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.

-

-2001-10-23  David Turner  <[email protected]>

-

-	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:

-	Improvements to the memory debugger to report more information in

-	case of errors.  Also, some allocations that occurred through REALLOC

-	couldn't be previously caught correctly.

-

-	* src/autohint/ahglyph.c (ah_outline_compute_segments,

-	ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),

-	src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced

-	liberal uses of memset() by the MEM_Set() macro.

-

-2001-10-23  David Turner  <[email protected]>

-

-	* src/raster/ftraster.c (Update): Removed to be inlined in ...

-	builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),

-	builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),

-	src/base/ftdbgmem.c: Updated the memory debugger and

-	platform-specific implementations of `ftsystem' in order to be able

-	to debug memory allocations on Unix, VMS and Amiga too!

-

-	* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed

-	some bogus warnings.

-

-	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:

-	Modified the debugging memory manager to report the location (source

-	file name + line number) where leaked memory blocks are allocated in

-	the source file.

-

-	* src/base/ftdbgmem.c: New debugging memory manager.  You must

-	define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it.  It

-	will record every memory block allocated and report simple errors

-	like memory leaks and double deletes.

-

-	* src/base/Jamfile: Include ftdbgmem.

-	* src/base/rules.mk: Ditto.

-	* src/base/ftbase.c: Include ftdbgmem.c.

-

-	* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY

-	macro definition.

-

-	* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the

-	base component to use the debugging memory manager when the macro

-	FT_DEBUG_MEMORY is defined.

-

-2001-10-21  Tom Kacvinsky  <[email protected]>

-

-	* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if

-	we are working with a CID keyed CFF font.  Otherwise, a variable

-	that was never allocated memory might freed.  This is a correction

-	to the previous patch for freeing subfonts.

-

-2001-10-21  Tom Kacvinsky  <[email protected]>

-

-	* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to

-	avoid a memory leak.

-

-2001-10-21  David Turner  <[email protected]>

-

-	* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,

-	src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes

-	(in multi-object compilation mode, mainly).

-

-2001-10-20  Tom Kacvinsky  <[email protected]>

-

-	* src/type1/t1load.c (parse_encoding): Add a test to make sure

-	that custom encodings (i.e., neither StandardEncoding nor

-	ExpertEncoding) are not loaded twice when the Type 1 font is

-	synthetic.

-

-	* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test

-	for when loading synthetic fonts to make sure that the font name

-	and subroutines are not loaded twice.  This is to remove a memory

-	leak that occurred because the original memory blocks for these

-	objects were not deallocated when the objects were parsed the

-	second time.

-

-2001-10-19  David Turner  <[email protected]>

-

-	* src/smooth/ftgrays.c, src/pshinter/pshglob.h,

-

-	* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the

-	`glnames.py' script used to generate the `pstables.h' header file.

-	The old one contained a serious bug that made FreeType return

-	incorrect glyph names for certain glyphs.

-

-	* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of

-	pixel size from character size to use rounding.  This is an

-	experiment to see whether this gives values similar to Windows for

-	scaled ascent/descent/etc.

-

-	* src/base/ftcalc.c (FT_Div64by32): Changed the implementation

-	slightly since the original code was mis-compiled on Mac machines

-	using the MPW C compiler.

-

-	* src/base/ftobjs.c (FT_Realloc): When a memory block was grown

-	through FT_Realloc(), the new bytes were not set to 0, which created

-	some strange bugs in the PostScript hinter.

-	(destroy_face): Don't deallocate unconditionally.

-

-	* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):

-	Adding support to new PostScript hinter.

-

-	* include/freetype/internal/psglobal.h,

-	include/freetype/internal/pshints.h,

-	include/freetype/config/ftmodule.h, src/pshinter/Jamfile,

-	src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h,

-	src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,

-	src/type1/t1objs.h: Updates to use the new PostScript hinter.

-

-	* tests/Jamfile, tests/gview.c: Adding a new glyph hinting

-	viewer/debugger to the source tree.  Note that you will _not_ be

-	able to compile it since it depends on an unavailable graphics

-	library named `Nirvana' to render vector images.

-

-2001-10-17  David Turner  <[email protected]>

-

-

-	* Version 2.0.5 released.

-	* doc/BUGS, doc/TODO: New documents.

-

-2001-10-07  Richard Barber  <[email protected]>

-

-	* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented

-

-	* src/smooth/ftgrays.c: Include <setjmp.h>.

-	(ErrRaster_MemoryOverflow): New macro.

-	(TArea): New type to store area values in each cell (using `int' was

-	this is used in embedded fonts.

-

-	* src/psaux/psobjs.c (PS_Table_Add): Fixed a reallocation bug that

-	generated a dangling pointer reference.

-

-2001-08-30  Anthony Feik  <[email protected]>

-

-	* src/type1/t1afm.c (T1_Read_AFM): Now correctly sets the flag

-	FT_FACE_FLAG_KERNING when appropriate for Type1 + AFM files.

-

-

-	* src/sfnt/ttload.c (TT_Load_CMap): Fix frame length of

-2001-08-21  David Turner  <[email protected]>

-

-	* include/freetype/config/ftoption.h: Changed the default setting

-	for FT_CONFIG_OPTION_USE_MODULE_ERRORS to undefined, since it breaks

-

-2001-08-17  Martin Muskens  <[email protected]>

-

-	* src/base/ftcalc.c (FT_MulDiv): Fixed serious typo.

-

-2000-12-21  David Turner  <[email protected]>

-

-	we'll work on supporting CID AFM files later I guess :-)

-

-2000-12-21  Tom Kacvinsky  <[email protected]>

-

-	* src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):

-	Changed so that fonts with a non-standard FontMatrix render

-	font did not have the transformation matrix applied.

-

-2000-12-17  Werner Lemberg  <[email protected]>

-

-	* *.mk: Added lots of `.PHONY' targets.

-

-2000-12-17  Karsten Fleischer  <[email protected]>

-

-	* INSTALL: Added info about makepp.

-

-2000-12-14  David Turner  <[email protected]>

-

-	Added support for clipped direct rendering in the smooth renderer.

-	This should not break binary compatibility of existing applications.

-

-	* include/freetype/fttypes.h, include/freetype/ftimage.h: Move

-	definition of the FT_BBox structure from the former to the latter.

-	* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to

-	FT_Raster_Flag enumeration.

-	Add `clip_box' element to FT_Raster_Params structure.

-	* src/smooth/ftgrays.c (grays_convert_glyph): Implement it.

-	* src/raster/ftraster.c (ft_black_render): Test for unsupported

-	direct rendering before testing arguments.

-

-2000-12-13  David Turner  <[email protected]>

-

-	* include/freetype/config/ft2build.h,

-	include/freetype/internal/internal.h: Fixed header inclusion macros

-	to use direct definitions.  This is the only way to do these things

-	in a portable way :-(  The rest of the code should follow shortly

-	though everything compiles now.

-

-	* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.

-

-	* builds/win32/detect.mk: Added support for the Intel C/C++

-	compiler, as well as _preliminary_ (read: doesn't work!) support for

-	a list of supported command-line compilers on Win32.

-

-	* src/base/ftdebug.c: Added dummy symbol to avoid empty file if

-	conditionals are off.

-

-2000-12-13  Werner Lemberg  <[email protected]>

-

-	* builds/unix/ftsystem.c: Fixed typos.  Fixed inclusion of wrong

-	ftconfig.h file.

-

-2000-12-12  Werner Lemberg  <[email protected]>

-

-	* include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):

-	Removed.  ANSI C doesn't (explicitly) allow macro expansion in

-	arguments using `##'.

-	(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory

-	names directly.  Make them configurable.  Use `##' to strip leading

-	and trailing spaces from arguments.

-

-	* builds/unix/ft2unix.h: Adapted.

-

-	* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,

-

-2000-12-09  Werner Lemberg  <[email protected]>

-

-2000-12-08  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttinterp.c: Remove unused CALC_Length() macro.

-

-

-2000-12-05  David Turner  <[email protected]>

-

-

-	* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:

-	The ANSI `free()' function was called instead of `memory->free()'.

-

-	* docs/docmaker.py: Added section filtering, multi-page generation

-	(index page generation is still missing though).

-

-2000-12-04  David Turner  <[email protected]>

-

-	* builds/unix/install.mk, builds/unix/ft2unix.h: The file `ft2unix.h'

-	is now installed as <ft2build.h> for Unix systems.  Note that we

-	still use the `freetype2/freetype' installation path for now.

-

-	* */*.[ch]: Now using <ft2build.h> as the default build and setup

-	configuration file in all public headers.  Internal source files

-	still need some changes though.

-

-	* INSTALL: Revised.

-	* builds/compiler/bcc-dev.mk, builds/compiler/visualage.mk,

-	`setup'.

-

-2000-11-30  David Turner  <[email protected]>

-

-	* INSTALL: Slightly updated the quick starter documentation to

-	include IDE compilation, prevent against BSD Make, and specify `make

-	setup' instead of a single `make' for build configuration.

-

-	* include/config/ftbuild.h, include/internal/internal.h: Added new

-	configuration files used to determine the location of all public,

-	configuration, and internal header files for FreeType 2.  Modified

-	that we still need to change the library source files themselves

-	though.

-

-	* builds/compiler/bcc.mk, builds/compiler/bcc-dev.mk,

-	builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk,

-	src/truetype/ttobjs.c, src/truetype/ttgload.c,

-	src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++

-	didn't really like.  Basically, this compiler complains when FT_UInt

-	is compared to FT_UShort (apparently, it promotes `UShort' to `Int'

-	in these cases).

-

-2000-11-30  Tom Kacvinsky  <[email protected]>

-

-	* t2objs.c (T2_Init_Face): Added calculation of `face->height' for

-

-	Say you have `(Foo*)x' and want to assign, pass, or return it as

-	`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler

-	would warn you that type casting incompatible pointer types breaks

-	strict-aliasing.  The solution is to cast to `(void*)' instead which

-	is the generic pointer type, so the compiler knows that it should

-	make no strict-aliasing assumption on `x'.  But the problem with

-	`(void*)x' is that seems like in C++, unlike C, `void*' is not a

-	generic pointer type and assigning `void*' to `Bar*' without a cast

-	causes an error.  The solution is to cast to `Bar*' too, with

-

-2005-02-25  David Turner  <[email protected]>

-

-	Implement several memory optimizations to drastically reduce the

-	heap usage of FreeType, especially in the case of memory-mapped

-	files.  The idea is to avoid loading and decoding tables in the

-	heap, and instead access the raw data whenever possible (i.e., when

-	it doesn't compromise performance).

-

-	This has several benefits: For example, opening vera.ttf now uses

-	just a small amount of memory (even when the FT_Library footprint is

-	accounted for), until you start loading glyphs.  Even then, you save

-	at least 20KB compared to the non-optimized case.  Performance of

-	various operations, including open and close, has also been

-	dramatically improved.

-

-	More optimizations to come, especially for the auto-hinter.

-

-	* include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New

-	function type.

-	(SFNT_Interface): Add it.

-	`hdmx_record_sizes', `kern_table', `kern_table_size,

-	`num_kern_tables', `kern_avail_bits', `kern_order_bits' if

-	FT_OPTIMIZE_MEMORY is set.

-	Don't define `hdmx', `num_kern_pairs', `kern_table_index',

-	`kern_pairs' if FT_OPTIMIZE_MEMORY is set.

-

-	* src/base/ftdbgmem.c (ft_mem_table_set): Don't shadow variable.

-	=========================

-

-

-	compiler warnings.

-

-2004-06-23  Werner Lemberg  <[email protected]>

-

-2004-06-23  David Turner  <[email protected]>

-	* include/freetype/internal/ftmemory.h, src/base/ftutil.c

-	(FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,

-	FT_QRealloc_Debug): New functions that perform allocation without

-	Small optimization in the kerning table verifier; this speeds up

-	TrueType face opening by about 7%.

-	(tt_face_load_hdmx): Use FT_QNEW_ARRAY and FT_QALLOC.

-

-	* include/freetype/config/ftmodule.h: Changed the order of modules,

-	putting TrueType and Type 1 first.  This dramatically improves the

-	performance of face open/close operations.  For example, putting the

-	TrueType driver first in the list results in a 5x speedup when

-	opening `Vera.ttf'.

-

-	The very problem is that both the PCF and BDF drivers do a lot more

-	than necessary to detect that they cannot handle a font file.

-

-	* src/autofit/*: Important fixes to the auto-fitter.  The output

-	now seems to be 100% equivalent to the auto-hinter, while being

-	about 2% faster (which proves that script-specific algorithm

-	selection isn't a performance problem).

-

-	To test it, change `autohint' to `autofit' in

-	<freetype/config/ftmodule.h> and recompile.

-

-	A few more testing is needed before making this the official

-	auto-hinting module.

-2004-02-10  Werner Lemberg  <[email protected]>

-

-	Make the PS parser more tolerant w.r.t. non-standard font data.  In

-	general, an error is only reported in case of a syntax error; a

-	wrong type is now simply ignored (if possible).  To be independent

-	of the order of various MM-specific keywords, the parse_shared_dict

-	routine has been removed -- the PS parser is now capable to skip

-	this data.  It no longer fails on parsing e.g.

-

-	  dup /WeightVector exch def

-

-	Since the token following /WeightVector isn't `[' (starting an

-	array) it is simply ignored.

-

-	* include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a

-	new internal error value.

-

-	structure, if necessary.

-	Return T1_Err_Ignore if no proper array is following the keyword.

-	(parse_shared_dict): Removed.

-	(parse_encoding): Set parser->root.error to return T1_Err_Ignore

-	if no result can be obtained.

-	Check for errors before accessing `elements' array.

-	(t1_keywords): Remove /shareddict.

-	(parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore.

-	Set keyword_flag only in case of success.

-	Check error code if skipping an unrecognized token.

-	(T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend

-	if blend commands haven't set up a proper MM font.

-

-	* src/psaux/psobjs.c (ps_parser_load_field_table): Remove special

-	code for synthetic fonts.

-	Return PSaux_Err_Ignore if no proper value has been found.

-	(T1_Open_Face): Improve an error message.

-

-2004-02-01  Werner Lemberg  <[email protected]>

-

-	* src/type1/t1load.c (parse_charstrings): Exit immediately if

-	there are no elements in /CharStrings.  This is needed for fonts

-	like Optima-Oblique which not only define /CharStrings but access it

-	also.

-	(parse_dict): Skip all /CharStrings arrays but the first.  We need

-	this for non-standard fonts like `Optima' which have different

-	outlines depending on the resolution.  Note that there is no

-	guarantee that we get fitting /Subrs and /CharStrings arrays; this

-	can only be done by a real PS interpreter.

-

-	  *Complete* rewrite of the cache sub-system to `solve' the

-	  following points:

-

-	    - all public APIs have been moved to FT_CACHE_H, everything

-	      under `include/freetype/cache' is only needed by client

-	      applications that want to implement their own caches

-

-	    - a new function named FTC_Manager_RemoveFaceID to deal

-	      with the uninstallation of FaceIDs

-

-	    - the image and sbit cache are now abstract classes, that

-	      can be extended much more easily by client applications

-

-	    - better performance in certain areas.  Further optimizations

-	      to come shortly anyway...

-

-	    - the FTC_CMapCache_Lookup function has changed its signature,

-	      charmaps can now only be retrieved by index

-

-	    - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace

-	      FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in

-	      private header for the moment)

-2003-06-08  Werner Lemberg  <[email protected]>

-

-	Completely revised FreeType's make management.

-

-	. In all makefiles `/' is used as the path separator.  The

-	  conversion to the real path separators is done as late as

-	  possible using $(subst ...).

-

-	. $(HOSTSEP) no longer exists.  Now, $(SEP) gives the path separator

-	  for the operating system, and the new $(COMPILER_SEP) the path

-	  separator for the compiler tools.

-

-	. $(BUILD) has been renamed to $(BUILD_DIR).  In general, all

-	  directory variables end with `_DIR'.  The variants ending in `_'

-	  (like `BASE_' have been removed).

-

-	The following ChangeLog entries only describe changes which are

-	not related to the redesign.

-

-	* builds/beos/beos-def.mk (BUILD_DIR): Fix typo.

-

-	* include/freetype/config/ftoption.h: Defining

-

-	* src/truetype/ttgload.c (load_truetype_glyph)

-	similar to the PCF driver.

-	* src/bdf/bdf.h (_hashnode): Use `const' for `key'.

-

-	* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'

-	files directly instead of this hack.

-	(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts

-	to make build with g++ successful.

-

-

-2003-04-24  David Turner  <[email protected]>

-

-	* src/pcf/pcfread.c (pcf_load_font): Fixed the computation of

-	face->num_glyphs.  We must increase the value by 1 to respect the

-	glyph'.

-

-2003-04-24  Werner Lemberg  <[email protected]>

-

-

-	* src/type1/t1load.c (T1_Open_Face): Fixed the code to make it

-

-2003-03-27  David Turner  <[email protected]>

-

-	* README: Updated.

-

-	* README.UNX: Removed (now replaced by docs/INSTALL.UNX).

-	more general names according to the PostScript specification (the

-	previous one was too restrictive).

-

-	These functions are much more convenient to use than managing the

-	FT_GLYPH_OWN_BITMAP flag manually.

-

-2003-03-15  David Turner  <[email protected]>

-

-	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding

-	bug.  Actually, it seems that previous versions of FreeType didn't

-	perform TrueType rounding exactly as appropriate.

-

-2003-03-14  David Turner  <[email protected]>

-

-	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small

-	TrueType native rendering glitches; they came from a small rounding

-	error.

-

-2003-03-13  David Turner  <[email protected]>

-

-	Added new environment variables to control memory debugging with

-	FreeType.  See the description of `FT2_DEBUG_MEMORY',

-	`FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT.

-

-	* src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count',

-2003-02-25  Anthony Fok  <[email protected]>

-

-	* src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H.

-	(ftc_cmap_family_init): The cmap cache now

-	in comments.

-

-2003-02-25  David Turner  <[email protected]>

-

-	* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that

-	caused FreeType to loop endlessly when trying to read certain

-	compressed gzip files.  The following test reveals the bug:

-

-	  touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz

-

-	Several fixes to the PFR font driver:

-

-	- The list of available embedded bitmaps was not correctly set in

-	  the root FT_FaceRec structure describing the face.

-

-	- The glyph loader always tried to load the outlines when

-	  FT_LOAD_SBITS_ONLY was specified.

-

-	- The table loaded now scans for *undocumented* elements of a

-	  physical font's auxiliary data record.  This is necessary to

-	  retrieve the `real' family and style names.

-

-	NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS!

-

-	* src/pfr/pfrload.c (pfr_aux_name_load): New function.

-	(pfr_phy_font_done): Free `family_name' and `style_name' also.

-	Remove unused variables.

-	(pfr_phy_font_load): Extract useful information from the auxiliary

-	bytes.

-

-	* src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL.

-	(pfr_face_init): Provide fallback values for `family_name' and

-	`style_name'.

-	Handle strikes.

-	(pfr_slot_load): Handle FT_LOAD_SBITS_ONLY.

-	* src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent',

-	`descent', `leading', `family_name', and `style_name'.

-

-	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug

-	when computing the scale factors for a given character size in

-	points with resolution.

-

-	* devel/ft2build.h, devel/ftoption.h: New files (in a new directory)

-	which are special development versions of include/ft2build.h and

-	include/freetype/config/ftoption.h, respectively.

-

-2003-02-18  David Turner  <[email protected]>

-

-	Fixing the slight distortion problem that occurred due to the latest

-	auto-hinter changes.

-

-	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding.

-

-	* src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'.

-	[!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed.

-

-	* src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'.

-	* src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of

-	`metrics'.

-	[FT_CONFIG_CHESTER_ASCENDER]: Code removed.

-	(Reset_SBit_Size): Fix initialization of `metrics'.

-

-	* src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of

-	`exec->metrics'.

-

-	* src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width

-	`correction' which seemed to provide more trouble than benefits.

-

-2003-02-13  Graham Asher  <[email protected]>

-

-	Changed the incremental loading interface in a way that makes it

-	simpler and allows glyph metrics to be changed (e.g., by adding a

-	constant, as required by CFF fonts) rather than just overridden.

-	This was required to make the GhostScript-to-FreeType bridge work.

-

-	* src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]:

-	Allow metrics to be overridden.

-	* src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]:

-	Ditto.

-

-	* src/truetype/ttgload.c (load_truetype_glyph)

-	[FT_CONFIG_OPTION_INCREMENTAL]: Simplify.

-	(compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block

-	moved down.

-

-	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String)

-	[FT_CONFIG_OPTION_INCREMENTAL]: Updated.

-

-	* include/freetype/ftincrem.h: Updated.

-

-2003-01-31  David Turner  <[email protected]>

-

-	* docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation

-	for the 2.1.4 release.

-

-	* builds/win32/visualc/freetype.dsp,

-	builds/win32/visualc/index.html: Updating the project file for

-	2.1.4.

-

-	* src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c,

-	src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c,

-	src/gzip/infutil.c: Removed old-style (K&R)function definitions.

-	This avoids warnings with Visual C++ at its most pedantic mode.

-

-	* src/pfr/pfrsbit.c: Removed compiler warnings.

-

-	* src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR

-	into an FT_TRACE1 since it caused `ftview' and others to dump too

-	much junk when trying to display a waterfall with a font without a

-	Unicode charmap (e.g.  SYMBOL.TTF).

-

-	Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last

-	patch from David Chester, but with a much simpler (and saner)

-	implementation.

-

-	* src/autohint/ahhint.c (ah_hinter_load_glyph)

-	[FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that

-	the top of non-capital letters is aligned on a pixel boundary

-	whenever possible.

-

-	* src/base/ftobjs.c (FT_Set_Char_Size)

-	[FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently.

-	* src/truetype/ttdriver.c (Set_Char_Sizes)

-	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only

-	if this macro is defined.

-

-	* src/truetype/ttobjs.c (Reset_Outline_Size)

-	[FT_CONFIG_CHESTER_ASCENDER]: Round differently.

-

-	* src/pshinter/pshalgo3.c: Improved the Postscript hinter.  Getting

-	rid of stem snapping seems to work well here (though the stems are

-	still slightly moved to increase contrast).

-	(psh3_dimension_quantize_len): Commented out.

-	(psh3_hint_align_light): New function.

-	(psh3_hint_align): Comment out some code.

-

-	THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES

-	STILL SUCK.

-

-2003-01-22  David Chester  <[email protected]>

-

-	* src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the

-	stem width optimization.

-

-2003-01-22  David Turner  <[email protected]>

-	properties of a given PCF or BDF font.

-

-	* include/freetype/ftbdf.h (BDF_PropertyType): New enumeration.

-	(BDF_Property, BDF_PropertyRec): New structure.

-	* src/pcf/pcfdrivr.c: Include FT_BDF_H.

-	(pcf_get_bdf_property, pcf_driver_requester): New functions

-	(pcf_driver_class): Use `pcf_driver_requester'.

-

-	* src/pcf/pcfread.c: Include `pcfread.h'.

-	(pcf_find_property): Decorate it with FT_LOCAL_DEF.

-	* src/pcf/pcfread.h: New file, providing `pcf_find_property'.

-

-	* src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size

-	verification to accept a few broken fonts who pad the size

-	incorrectly (the table should be padded, but its `size' field

-	shouldn't according to the specification).

-

-2003-01-18  Werner Lemberg  <[email protected]>

-

-	* builds/unix/ltmain.sh: Regenerated with `libtoolize --force

-	--copy' from libtool 1.4.3.

-	FT_Size_Metrics.

-

-2003-01-15  James Su  <[email protected]>

-

-	* src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read

-	certain gzip-ed font files (typo: `&&' -> `&').

-

-2003-01-15  Huw D M Davies  <[email protected]>

-

-	Added a Windows .FNT specific API (mostly for Wine).  Also fixed a

-	nasty bug in the header loader which would cause invalid memory

-	overwrites.

-

-	* include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro

-	for ftwinfnt.h.

-	* include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H.

-	(FNT_FontRec): Updated.

-	Move Windows FNT definition to...

-	* include/freetype/ftwinfnt.h: This new file.

-

-	* include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to

-	the type of the first argument to FT_Matrix_Multiply, which isn't

-	changed -- this adds documentation and convenience.

-

-2003-01-13  Graham Asher  <[email protected]>

-

-	* src/sfnt/ttload.c (tt_face_load_metrics)

-	[FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without

-	horizontal metrics (without the `hmtx' table) are now tolerated if

-	an incremental interface has been specified that has a

-	get_glyph_metrics function, implying that metrics will be supplied

-	from outside.  This happens for certain Type 42 fonts passed from

-	GhostScript.

-

-2003-01-11  David Chester  <[email protected]>

-

-	Patches to the auto-hinter in order to slightly improve the output.

-	Note that everything is controlled through the new

-	FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'.  There are

-	also individual FT_CONFIG_CHESTER_XXX macros to control individual

-	`features'.

-

-	Note that all improvements are enabled by default, but can be

-	tweaked for optimization and testing purposes.  The configuration

-	macros will most likely disappear in the short future.

-

-	* include/freetype/config/ftoption.h

-	(FT_CONFIG_OPTION_CHESTER_HINTS): New macro.

-	(FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE})

-	* src/autohint/ahglyph.c (ah_outline_compute_edges)

-	[FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'.

-	(ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]:

-	Increase threshold for `best_dist'.

-	* src/autohint/ahhint.c (ah_compute_stem_width)

-	[FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif

-	handling.

-	(ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special

-	version of `ah_compute_stem_width'.

-	(ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem

-	alignment when stem widths are less than 1.5 pixels wide centers the

-	stem slightly off-center of the center of a pixel (this increases

-	sharpness and consistency).

-	[FT_CONFIG_CHESTER_SERIF]: Use special version of

-	`ah_compute_stem_width'.

-	* src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add

-	`AH_BLUE_SMALL_F_TOP'.

-

-2003-01-11  David Turner  <[email protected]>

-	`reserved2', not `reserved'.

-

-	* src/base/ftobjs.c (find_unicode_charmap): Fixed the error code

-	returned when the font doesn't contain a Unicode charmap.  This

-	allows FT2 to load `symbol.ttf' and a few others correctly since the

-	last release.

-	(open_face): Fix return value.

-

-2003-01-08  Owen Taylor  <[email protected]>

-

-	Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and

-	postscript hinters.

-

-2003-01-08  David Turner  <[email protected]>

-

-2003-01-07  David Turner  <[email protected]>

-

-

-2002-11-27  Vincent Caron  <[email protected]>

-

-	* builds/unix/unix-def.in, builds/unix/freetype-config.in,

-	builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c

-	width quantization.  It produces slightly better shapes though this

-	is not distinguishable with many fonts.

-	Remove other dead code.

-

-	* src/Jamfile, src/*/Jamfile: Simplified.

-	Use $(FT2_SRC_DIR).

-

-2002-11-06  David Turner  <[email protected]>

-

-	* include/freetype/freetype.h (FT_LOAD_TARGET_LIGHT): New macro.

-	(FT_LOAD_TARGET, FT_LOAD_TARGET_MODE): Use `& 15' instead of `& 7'.

-

-2002-11-05  David Turner  <[email protected]>

-

-	* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: Added

-	support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify

-	the use of system-wide zlib.

-

-	Note that this macro, as well as

-	TT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore.

-	This allows the build system to define them depending on the

-	configuration (typically by adding -D flags at compile time).

-

-	* src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler

-	warnings in optimized mode relative to the `volatile' local

-	variables.  This was not a compiler bug after all, but the fact that

-	a pointer to a volatile variable is not the same as a volatile

-	pointer to a variable :-)

-

-	The fix was to change

-	  `volatile FT_Byte* p'

-	into

-	  `FT_Byte* volatile p'.

-

-	* src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c

-	(pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in

-	optimized modes.

-

-	* src/gzip/*.[hc]: Modified our zlib copy in order to prevent

-	exporting any zlib function names outside of the component.  This

-	prevents linking problems on some platforms, when applications want

-	to link FreeType _and_ zlib together.

-

-2002-11-05  Juliusz  <[email protected]>

-

-	* src/psaux/psobjs.c (ps_table_add): Modified increment loop in

-	* src/base/ftobjs.c (ft_glyphslot_clear): Small internal fix to

-	better support bitmap-based font formats.

-2002-08-27  David Turner  <[email protected]>

-

-	* Massive re-formatting changes to many, many source files.  I don't

-	want to list them all here.  The operations performed were all

-	logical transformations of the sources:

-

-	- trying to convert all enums and constants to CAPITALIZED_STYLE,

-	  #with define definitions like

-

-	    #define my_old_constants   MY_NEW_CONSTANT

-

-	- big, big update of the documentation comments

-

-	* include/freetype/freetype.h, src/base/ftobjs.c,

-	src/smooth/ftsmooth.c, include/freetype/ftimage.h: Adding support

-	for LCD-optimized rendering though the new constants/enums:

-

-	  FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V

-	  FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

-

-	This is still work in progress, don't expect everything to work

-	correctly though most of the features have been implemented.

-

-	* Adding new FT_LOAD_XXX flags, used to specify both hinting and

-	rendering targets:

-

-	  FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering

-	  FT_LOAD_TARGET_MONO   :: monochrome bitmaps

-	  FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated

-	                           hinting & rendering

-	  FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated

-	                           hinting & rendering

-

-	Note that FT_LOAD_TARGET_NORMAL is 0, which means that the default

-	behaviour of the font engine is _unchanged_.

-

-	* docs/VERSION.DLL: New file.

-

-2002-08-23  Graham Asher  <[email protected]>

-

-	* src/cff/cffgload.c (cff_operator_seac)

-	[FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not

-	incremental in the case of CFF but just using callbacks to get glyph

-	recipes) pass the character code, not the glyph index, to the

-	get_glyph_data function; they have no valid charset table.

-

-	* src/cff/cffload.c (cff_font_load): Removed special cases for

-	FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF

-	fonts provided via the incremental interface now have to conform

-	more closely to the CFF font format.

-

-	* src/cff/cffload.h (cff_font_load): Removed argument now unneeded.

-

-	* src/cff/cffobjs.c (cff_face_init): Changed call to cff_font_load

-	to conform with new signature.

-	compiler warnings and resolve shadowing of local variables.

-

-2002-08-21  David Turner  <[email protected]>

-

-	The automatic and Postscript hinter now automatically detect

-	inflection points in glyph outlines and treats them specially.  This

-	is very useful to prevent nasty effect like the disappearing

-	diagonals of `S' and `s' in many, many fonts.

-

-	* src/autohint/ahtypes.h (ah_flag_inflection): New macro.

-

-	* include/freetype/freetype.h: Changing the type of the `load_flags'

-	parameter from `FT_Int' to `FT_Int32', this in order to support more

-	options.  This should only break binary and/or source compatibility

-	on 16-bit platforms (Atari?).

-	(FT_LOAD_NO_AUTOHINT): New macro.

-

-	* src/base/ftobjs.c (FT_Load_Glyph): Updated.

-	* src/raster/ftraster.c: s/wait/waiting/.

-

-2002-08-01  Graham Asher  <[email protected]>

-

-	* src/type1/t1load.c (T1_Open_Face): Tolerate a face with no

-	charstrings if there is an incremental loading interface.  Type 1

-	faces supplied by PostScript interpreters like GhostScript will

-	typically not provide any charstrings at load time, so this is

-	essential if they are to work.

-

-2002-08-01  Graham Asher  <[email protected]>

-

-	Modified incremental loading interface to be closer to David's

-	preferences.  The header freetype.h is not now affected, the

-	interface is specified via an FT_Parameter, the pointer to the

-	interface is hidden in an internal part of the face record, and all

-	the definitions are in ftincrem.h.

-

-	* include/freetype/freetype.h [FT_CONFIG_OPTION_INCREMENTAL]:

-	Removed.

-	* include/freetype/internal/ftobjs.h [FT_CONFIG_OPTION_INCREMENTAL]:

-

-	* src/truetype/ttobjs.c: Fix for bug reported by Sven Neumann

-	[[email protected]] on the FreeType development forum: `If

-	it tries to access face->glyph_locations.'

-

-2002-07-18  Graham Asher  <[email protected]>

-

-	Added types and structures to support incremental typeface loading.

-	The FT_Incremental_Interface structure, defined in freetype.h, is

-	designed to be passed to FT_Open_Face to provide callback functions

-	to obtain glyph recipes and metrics, for fonts like those passed

-	from PostScript that do not necessarily provide all, or any, glyph

-	information, when first opened.

-

-	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):

-	New configuration macro to enable incremental face loading.  By

-	default it is not defined.

-	system for the TrueType driver.

-

-	* src/cid/cidgload.c (cid_load_glyph)

-	[FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system

-	for the CID driver.

-

-	* src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]:

-	Changes to support incremental Type 42 fonts: Assume a font has

-	glyphs if it has an incremental interface object.

-

-	* src/type1/t1gload.c (T1_Parse_Glyph): Renamed to...

-	(T1_Parse_Glyph_And_Get_Char_String): This.

-	[FT_CONFIG_OPTION_INCREMENTAL]: Added support for incrementally

-	loaded Type 1 faces.

-2005-05-28  David Turner  <[email protected]>

-

-	* docs/CHANGES: Updating file for next release (2.1.1).

-

-	* src/bdf/bdflib.c: Removing compiler warnings.

-

-	* include/freetype/ftxf86.h, src/base/ftxf86.c: New files.

-	They provide a new API (FT_Get_X11_Font_Format) to retrieve an

-	X11-compatible string describing the font format of a given face.

-	This was put in a new optional base source file, corresponding to a

-	new public header (named FT_XFREE86_H since this function should

-	only be used within the XFree86 font server IMO).

-

-	* include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not

-	documented yet).

-

-	* src/base/fttype1.c: New file, providing two new API functions

-	(FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names).

-	* include/freetype/t1tables.h: Updated.

-

-	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:

-

-	* src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that

-	prevented family blue zones substitution from happening correctly.

-

-	* src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math

-	with calls to `FT_MulDiv'.

-

-2002-05-28  David Turner  <[email protected]>

-

-	Fixing the SFNT name table loader to support various buggy fonts.

-	It now ignores empty name entries, entries with invalid pointer

-	Offsets and certain fonts containing tables with broken

-	`storageOffset' fields.

-

-	Name strings are now loaded on demand, which reduces the memory

-	requirements for a given FT_Face tremendously (for example, the name

-	table of Arial.ttf is about 10Kb and contains 70 names).

-

-	This is a temporary fix.  The whole name table loader and interface

-	will be rewritten in a much more cleanly way shortly, once CSEH have

-	been introduced in the sources.

-

-	* include/freetype/internal/tttypes.h (TT_NameEntryRec): Change

-	type of `stringOffset' to FT_ULong.

-	(TT_NameTableRec): Change type of `numNameRecords' and

-	`storageOffset' to FT_UInt.

-	Replace `storage' with `stream'.

-	* src/base/ftnames.c (FT_Get_Sfnt_Name): Load name on demand.

-	* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.

-	Make code more robust.

-	* src/sfnt/sfobjs.c (TT_NameEntry_ConvertFunc): New typedef.

-	(tt_face_get_name): Use it.

-	Make code more robust.

-	* src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays.

-	Handle invalid `storageOffset' data better.

-	Set length fields to zero for invalid or ignored data.

-	Remove code within FT_DEBUG_LEVEL_TRACE.

-	(TT_Free_Names): Updated.

-

-2002-05-24  Tim Mooney  <[email protected]>

-

-	* builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and

-	FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be

-	rebuilt from sources.  Set macro serial to 1, and use third argument

-	to AC_DEFINE for our two custom symbols, so ftconfig.in could one day

-	be rebuilt with autoheader (not recommended now, ftconfig.in is a

-	custom source file)

-

-2002-05-22  Werner Lemberg  <[email protected]>

-

-	* include/freetype/config/ftheader.h (FT_BEZIER_H): Removed.

-2002-05-21  David Turner  <[email protected]>

-

-	* src/bdf/bdflib.c: Removed compiler warning, and changed all tables

-	to the `static const' storage specifier (instead of simply

-	`static').

-

-	* src/type42/t42drivr.c (hexval): Use more efficient code.

-	Removing compiler warnings.

-	* src/bdf/bdfdrivr.c: Removing compiler warnings.

-

-	* include/freetype/internal/ftbdf.h, src/base/ftbdf.c,

-	src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk

-	(FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings

-	from a face.  This is much cleaner than accessing the internal types

-	`BDF_Public_Face' defined in FT_INTERNAL_BDF_TYPES_H.

-	bug that prevented FreeType 2.x and FreeType 1.x to produce

-	bit-by-bit identical monochrome glyph bitmaps with native TrueType

-	hinting.  The culprit was a single-bit flag that wasn't set

-	correctly by the TrueType glyph loader.

-	is very likely that this file will disappear or be renamed in the

-	future.

-

-2002-03-06  David Turner  <[email protected]>

-

-	* src/type1/t1objs.c (T1_Face_Init), src/cid/cidobjs.c

-	(CID_Face_Init): Fixed another bug related to the

-	ascender/descender/text height of Postscript fonts.

-

-	* src/pshinter/pshalgo2.c (print_zone): Renamed to ...

-	(psh2_print_zone): This.

-	* src/pshinter/pshalgo1.c (print_zone): Renamed to ...

-	(psh1_print_zone): This.

-

-	* include/freetype/freetype.h, include/freetype/internal/ftobjs.h,

-	src/base/ftobjs.c: Adding the new FT_Library_Version API to return

-	the library's current version in dynamic links.

-	* src/base/ftinit.c (FT_Init_FreeType): Updated.

-

-2002-03-06  Werner Lemberg  <[email protected]>

-

-	* src/pshinter/pshglob.h (PSH_DimensionRec): s/std/stdw/.

-	* src/pshinter/pshglob.c (psh_global_scale_widths,

-	psh_dimension_snap_width, psh_globals_destroy, psh_globals_new):

-	Ditto.

-

-2002-03-05  David Turner  <[email protected]>

-

-	* src/type1/t1objs.c (T1_Face_Init), src/cff/cffobjs.c

-	(CFF_Face_Init), src/cid/cidobjs.c (CID_Face_Init): Removing the bug

-	that returned global BBox values in 16.16 fixed format (instead of

-	integer font units).

-

-	* src/cid/cidriver.c (cid_get_postscript_name): Fixed a bug that

-	caused the CID driver to return Postscript font names with a leading

-	slash (`/') as in `/MOEKai-Regular'.

-

-	* src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),

-	src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so

-	that it accepts broken fonts like `foxjump.ttf', which made FreeType

-	crash when trying to load them.

-

-	Also improved the name table parser to be able to load

-	Windows-encoded entries before Macintosh or Unicode ones, since it

-	seems some fonts don't have reliable values here anyway.

-

-	* include/freetype/internal/psnames.h: Add typedef for

-	`PSNames_Service'.

-

-2002-03-05  Werner Lemberg  <[email protected]>

-

-	* builds/unix/aclocal.m4, builds/unix/ltmain.sh: Update to libtool

-	1.4.2.

-	Apply a small patch for AIX to make shared libraries work (this

-	patch is already in the CVS version of libtool).

-

-	* builds/unix/config.sub, builds/unix/config.guess: Updated to

-	recent versions.

-

-	* builds/unix/configure.ac: Fix typo

-	(AC_CONFIG_FILE->AC_CONFIG_FILES).

-

-	* builds/unix/configure: Regenerated.

-

-2002-02-28  David Turner  <[email protected]>

-

-	* include/freetype/ftconfig.h: Changed `FT_LOCAL xxxx' to

-	`FT_LOCAL( xxxx )' everywhere in the source.  The same goes for

-	`FT_LOCAL_DEF xxxx' which is translated to `FT_LOCAL_DEF( xxxxx )'.

-

-	* include/freetype/freetype.h (FREETYPE_MINOR, FREETYPE_PATCH):

-	Changing version to 2.1.0 to indicate an unstable branch.

-	Added the declarations of FT_Get_First_Char and FT_Get_Next_Char.

-

-	* src/base/ftobjs.c: Implement FT_Get_First_Char and

-	FT_Get_Next_Char.

-

-	* include/freetype/t1tables.h: Renaming structure types.  This

-

-	  typedef  T1_Struct_

-	  {

-	  } T1_Struct;

-

-	becomes

-

-	  typedef  PS_StructRec_

-	  {

-	  } PS_StructRec, *PS_Struct;

-

-	  typedef PS_StructRec  T1_Struct;  /* backward compatibility */

-

-	Hence, we increase the coherency of the source code by effectively

-	using the `Rec' prefix for structure types.

-

-2002-02-27  David Turner  <[email protected]>

-

-	* src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the

-	names table loader.  Invalid individual name entries are now handled

-	correctly.  This allows the loading of very buggy fonts like

-	`foxjump.ttf' without allocating tons of memory and causing crashes.

-

-	* src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: Adding (still

-	experimental) code for OpenType Layout tables validation and

-	parsing.

-

-	* src/type1/t1cmap.h, src/type1/t1cmap.c: Adding (still

-	experimental) code for Type 1 charmap processing.

-

-	* src/sfnt/ttcmap0.c: New file.  It contains a new, still

-	experimental SFNT charmap processing support.

-

-	* include/freetype/internal/ftobjs.h: Adding validation support as

-	well as internal charmap object definitions (FT_CMap != FT_CharMap).

-

-2002-02-24  David Turner  <[email protected]>

-

-	* Renaming stream functions to the FT_<Subject>_<Action> scheme:

-

-	  FT_Seek_Stream    => FT_Stream_Seek

-	  FT_Skip_Stream    => FT_Stream_Skip

-	  FT_Read_Stream    => FT_Stream_Read

-	  FT_Read_Stream_At => FT_Stream_Read_At

-	  FT_Release_Frame  => FT_Stream_Release_Frame

-	  FT_Get_XXXX       => FT_Stream_Get_XXXX

-	  FT_Read_XXXX      => FT_Stream_Read_XXXX

-

-	  FT_New_Stream( filename, stream ) =>

-	    FT_Stream_Open( stream, filename )

-

-	    (The function doesn't create the FT_Stream structure, it simply

-	    initializes it for reading.)

-

-	  FT_New_Memory_Stream( library, FT_Byte*  base, size, stream ) =>

-	    FT_Stream_Open_Memory( stream, const FT_Byte* base, size )

-

-	  FT_Done_Stream  => FT_Stream_Close

-	  FT_Stream_IO    => FT_Stream_IOFunc

-	  FT_Stream_Close => FT_Stream_CloseFunc

-

-	  ft_close_stream => ft_ansi_stream_close (in base/ftsystem.c only)

-	  ft_io_stream    => ft_ansi_stream_io    (in base/ftsystem.c only)

-

-	* src/base/ftutil.c: New file.  Contains all memory and list

-	management code (previously in `ftobjs.c' and `ftlist.c',

-	respectively).

-

-	* include/freetype/internal/ftobjs.h: Moving all code related to

-	glyph loaders to ...

-	* include/freetype/internal/ftgloadr.h: This new file.

-	`FT_GlyphLoader' is now a pointer to the structure

-	`FT_GlyphLoaderRec'.

-	(ft_glyph_own_bitmap): Renamed to ...

-	(FT_GLYPH_OWN_BITMAP): This.

-	* src/base/ftobjs.c: Moving all code related to glyph loaders

-	to ...

-	* src/base/ftgloadr.c: This new file.

-	(FT_ASSERT): This.

-	Some stuff from ftdebug.h has been moved to ...

-

-	* include/freetype/internal/fttrace.h: New file, to define the trace

-	levels used for debugging.  It is used both to define enums and

-	toggle names for FT2_DEBUG.

-

-	* include/freetype/internal/internal.h: Updated.

-

-	* src/base/ftobjs.c, src/base/ftstream.c: Updated.

-

-2006-05-02  Werner Lemberg  <[email protected]>

-

-2006-05-02  David Turner  <[email protected]>

-

-	Update the memory management functions and macros to safely deal

-	with array size buffer overflows.  This corresponds to attempts to

-	allocate arrays that are too large.  For an example, consider the

-	following code:

-

-	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *

-	  count ); for ( nn = 0; nn < count; nn++ )

-	    array[nn] = read_item_from_file();

-

-	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the

-	multiplication overflows, and the array allocated os smaller than

-	the data read from the file.  In this case, the heap will be

-	trashed, and this can be used as a denial-of-service attack, or make

-	the engine crash later.

-

-	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new

-	count is no larger than `FT_INT_MAX/item_size', otherwise a new

-	error code `FT_Err_Array_Too_Large' will be returned.

-

-	Note that the memory debugger now works again when FT_DEBUG_MEMORY

-	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding

-	code is now the default.

-

-

-	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:

-	Don't use `extern'.

-

-	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error

-	code.

-

-	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)

-	[FT_DEBUG_MEMORY]: New macro.

-	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.

-	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

-	(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,

-	FT_MEM_FREE): Redefine.

-	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,

-	FT_MEM_QRENEW_ARRAY): Redefine.

-	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,

-	FT_MEM_QREALLOC_MULT): New macros.  Update callers where

-	appropriate.

-	(FT_MEM_SET_ERROR): Slightly redefine.

-

-

-	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)

-	[FT_DEBUG_MEMORY]: New global variables, replacing...

-	(FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and

-	`line_no'.  Update all callers.

-	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer

-	overflow.

-	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,

-	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

-

-	* src/base/ftmac.c (read_lwfn): Catch integer overflow.

-	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.

-	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.

-	(ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite.

-

-

-	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,

-	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the

-	place where the frames were entered, extracted, exited or released

-	in the memory debugger.

-

-	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:

-	Call ft_mem_free.

-	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.

-	(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.

-

-2006-04-30  suzuki toshiya  <[email protected]>

-

-	* src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos

-	initialization, remove extra cast to copy to pfb_lenpos.  This fixes

-	parsing of PFB fonts with MacOS resource fork (bug introduced

-	2003-09-11).  Patch provided by Huib-Jan Imbens <[email protected]>.

-

-2006-04-29  Werner Lemberg  <[email protected]>

-

-	Further C library abstraction.  Based on a patch from

-	[email protected].

-	C library functions.  Update all users accordingly (and catch some

-	other places where the C library function was used instead of the

-	wrapper functions).

-

-	* src/base/ftsystem.c: Don't include stdio.h and stdlib.h.

-	* src/gzip/zutil.h [MSDOS && !(__TURBOC__ || __BORLANDC__)]: Don't

-	include malloc.h.

-

-

-	* builds/unix/unix-def.in (datarootdir): Define, for autoconf 2.59c

-	and forthcoming versions.

-	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.

-

-	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and

-

-

-	Add a new API named FT_Get_TrueType_Engine_Type to determine whether

-

-

-	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization

-	if FT_CONFIG_OPTION_OLD_INTERNALS is used.  The is necessary because

-	Fix some compiler warnings.

-	(tt_face_get_metrics): Ditto.

-

-

-	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of

-	character advances.

-

-2006-02-20  David Turner  <[email protected]>

-

-

-2006-02-17  Werner Lemberg  <[email protected]>

-

-	* devel/ftoption.h: Synchronize with

-	include/freetype/config/ftoption.h.

-

-2006-02-16  David Turner  <[email protected]>

-

-	Massive changes to the internals to respect the internal object

-	layouts and exported functions of FreeType 2.1.7.  Note that the

-	cache sub-system cannot be fully retrofitted, unfortunately.

-

-	* include/freetype/config/ftoption.h

-	(FT_CONFIG_OPTION_OLD_INTERNALS): New macro.

-

-	* include/freetype/ftcache.h, include/freetype/cache/ftccache.h,

-	Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data

-	structures.

-

-	Move newly added structure elements to the end of the affected

-	structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is

-	defined) to assure binary compatibility with older FreeType

-	versions.

-	Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old

-	functions:

-

-	  ft_stub_set_char_sizes

-	  ft_stub_set_pixel_sizes

-

-	Rename the following internal functions to provide the old function

-	names as stubs:

-

-	  FT_Alloc          -> ft_mem_alloc

-	  FT_QAlloc         -> ft_mem_qalloc

-

-2006-02-15  Chia-I Wu  <[email protected]>

-

-	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove

-	unused `max_points' and `max_contours'.

-

-	* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c

-	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.

-

-	* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused

-	`max_components'.

-

-	* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused

-	`loadSize' and `loadStack'.

-

-	* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),

-	src/sfnt/ttload.c (tt_face_load_maxp): Update.

-

-	* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c

-	(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix

-	compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not

-	defined.

-

-	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix

-	possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.

-	(finally!)

-

-

-	For most OpenType tables, `tt_face_load_xxxx' simply loads the table

-	and `face->root' is set later in `sfnt_load_face'.  Here, we try to

-	make this work for _all_ tables.  Also improve tracing messages.

-

-	* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,

-	src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and

-	then exit.  Error handling or setting face->root is done later in

-	`sfnt_load_face'.

-

-	* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.

-	Mac bitmap-only fonts are not scalable.

-	Check that `face->header.Units_Per_EM' is not zero.

-	(LOAD_, LOADM_): Emit pretty trace messages.

-

-	* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics

-	from `eblc'.

-

-	* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c

-	(load_format_20, load_format_25, tt_face_get_ps_name): Use

-	face->max_profile.numGlyphs, instead of face->root.num_glyphs.

-

-2006-02-14  Werner Lemberg  <[email protected]>

-

-	* include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in

-	documentation that negative strength values are possible.

-	Give an example call.

-

-	* include/freetype/freetype.h (FT_GlyphSlotRec): Improve

-	documentation of `outline' field.

-

-	* src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H.

-	* src/sfnt/sfdriver.c: Include ttmtx.h.

-

-	* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.

-

-2006-02-14  Chia-I Wu  <[email protected]>

-

-	* src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.

-

-2006-02-14  Chia-I Wu  <[email protected]>

-

-	* src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply

-	return error if table is missing.

-	Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.

-

-	* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics

-	tables.  The last change makes Mac bitmap-only font not load and

-	this fixes it.

-

-	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation

-	error when FT_CONFIG_OPTION_INCREMENTAL is defined.

-

-2006-02-13  Chia-I Wu  <[email protected]>

-

-	Clean up the SFNT_Interface.  In this final pass, `load_hmtx' is

-	split from `load_hhea'.

-

-	* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,

-	src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.

-

-	* src/sfnt/sfobjs.c (sfnt_load_face): Update.

-

-2006-02-13  Chia-I Wu  <[email protected]>

-

-	* src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of

-	code...

-

-2006-02-13  Chia-I Wu  <[email protected]>

-

-	Clean up the SFNT_Interface.  In this pass, we want to treat the

-	font directory (offset table and table directory) as a normal table

-	like the others.  This also means that TTCs are no longer recognized

-	there but in `init_face'.

-

-	* include/freetype/internal/sfnt.h (SFNT_Interface),

-	src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are

-	combined and renamed to `load_font_dir'.

-

-	* src/sfnt/ttload.h, src/sfnt/ttload.c:

-	s/sfnt_dir_check/check_table_dir/.

-	`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.

-	`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined

-	and renamed to `tt_face_load_font_dir'.

-

-	* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.

-

-2006-02-13  Chia-I Wu  <[email protected]>

-

-	Clean up the SFNT_Interface.  Table loading functions are now named

-	after the tables' tags; `hdmx' is TrueType-specific and thus the

-	code is moved to the truetype module; `get_metrics' is moved here

-	from the truetype module so that the code can be shared with the cff

-	module.

-

-	This pass involves no real changes.  That is, the code is moved

-	verbatim mostly.  The only exception is the return value of

-	`tt_face_get_metrics'.

-

-	* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,

-	src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,

-	src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,

-	src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.

-

-	* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files.  Metrics-related

-	tables' loading and parsing code is moved to here.

-	Move `tt_face_get_metrics' here from the truetype module.  The

-	return value is changed from `void' to `FT_Error'.

-

-	* include/freetype/internal/fttrace.h: New trace: ttmtx.

-

-	* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and

-	parsing code is moved here.

-	New function `tt_face_load_prep' split from `tt_face_load_fpgm'.

-	`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

-

-	* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

-

-	* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

-

-2006-02-11  Chia-I Wu  <[email protected]>

-

-	* src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug...

-

-	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Use

-	AF_LatinMetricsRec as the dummy metrics because we cast the metrics

-	to it later in `af_latin_hints_link_segments'.

-

-2006-02-11  Chia-I Wu  <[email protected]>

-

-	* include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define

-	to enable autofit CJK script support.  (#define'd by default.)

-

-	* src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro.

-

-	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure

-	that `edge_distance_threshold' is always set.

-	(af_latin_hints_link_segments): Potential divide-by-zero bug.

-	Use latin constant in the scoring formula.

-

-	* src/autofit/afcjk.c: Minor updates due to the above three changes.

-

-	* docs/TODO, docs/CHANGES: Updated.

-

-2006-02-09  Chia-I Wu  <[email protected]>

-

-	Introduce experimental autofit CJK module based on akito's autohint

-	patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.

-

-	* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,

-	src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:

-	Add CJK module based on akito's autohint patch.

-

-	* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the

-	overlap length of the segments.

-	(AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros.

-

-	* src/autofit/aflatin.h (af_latin_metrics_init_widths),

-	src/autofit/aflatin.c (af_latin_metrics_init_widths): Made

-	`FT_LOCAL'.

-	Use the character given by the caller.

-	(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale

-	the thresholds.

-

-	* src/autofit/afloader.c (af_loader_load_g): Respect

-	AF_SCALER_FLAG_NO_ADVANCE.

-

-2006-02-09  Werner Lemberg  <[email protected]>

-

-	* src/cid/cidparse.c (cid_parse_new): Remove shadowing variable.

-

-2006-02-09  suzuki toshiya  <[email protected]>

-

-	* src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or

-	broken CIDFont.  Reported by Taek Kwan(TK) Lee (see ft-devel

-	2005-11-02).

-

-2006-02-08  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts'

-	option on UNIX platform.  It has been broken since 2006-01-11.

-

-2006-02-01  Werner Lemberg  <[email protected]>

-

-	* src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/.

-

-	* builds/unix/unixddef.mk: Actually do define PLATFORM (fixing

-	change from 2006-01-31).

-	(TOP_DIR, OBJ_DIR): Update.

-

-	* builds/unix/install.mk (install): Fix path for ftmodule.h.

-

-	* Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use

-

-	* builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR),

-	builds/win32/w32-dev.mk (TOP_DIR): Removed.  Defined elsewhere.

-

-2006-01-31  Werner Lemberg  <[email protected]>

-

-	Implement new, simplified module selection.  With GNU make it is now

-	sufficient to modify a single file, `modules.cfg', to control the

-	inclusion of modules and base extension files.

-

-	This change also fixes the creation of ftmodule.h; it now depends on

-	`modules.cfg' and thus is rebuilt only if necessary.

-

-	Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the

-	default location.

-

-	* modules.cfg: New file.

-

-	* builds/freetype.mk: Don't include `modules.mk'.

-	Include all `rules.mk' files as specified in `modules.cfg'.

-	(FTOPTION_FLAG, FTOPTION_H): New variables.

-	(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.

-	Add FTOPTION_FLAG.

-	($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.

-	(CONFIG_H): Add FTMODULE_H and FTOPTION_H.

-	(INCLUDES): Add DEVEL_DIR.

-	(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,

-	OBJ_M, OBJ_S): Use `:=', not `='.

-	(remove_ftmodule_h): New phony target to delete `ftmodule.h'.

-	(distclean): Add remove_ftmodule_h.

-

-	* builds/modules.mk: (MODULE_LIST): Removed.

-	(make_module_list, clean_module_list): Replace targets

-	with...

-	(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New

-	variables.  Reason for the change is that it is not possible to have

-	a phony prerequisite which is run only if the target file must be

-	rebuilt (phony prerequisites act like subroutines and are *always*

-	executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is

-	changed.

-	Update all callers.

-	($FTMODULE_H)): Rule to create `ftmodule.h', depending on

-	`modules.cfg'.

-

-	* builds/toplevel.mk: Rewrite and simplify module handling.

-	(MODULES_CFG, FTMODULE_H): New variables.

-	Include MODULES_CFG.

-	(MODULES): New variable to include all `module.mk' and `rules.mk'

-	files.  We no longer use make's `wildcard' function for this.

-

-	* Makefile (USE_MODULES): Remove.  Update all users.

-	(OBJ_DIR): Define it here.

-

-	* src/*/module.mk: Change

-

-	    make_module_list: foo

-	    foo: ...

-

-	to

-

-	    FTMODULE_H_COMMANDS += FOO

-	    define FOO

-	    ...

-	    endef

-

-	in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

-

-	* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

-

-	* builds/unix/detect.mk (setup): Always execute `configure' script.

-	(have_mk): Rename to...

-	(have_Makefile): This.

-	Don't use `strip' function.

-

-	* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is

-	defined.

-	(have_mk): Don't use `strip' function.

-	Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test

-	accordingly).

-

-	* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

-

-	* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,

-	builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define

-	BUILD_DIR but DEVEL_DIR for development header files.

-

-	* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),

-	builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in

-	(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

-

-	* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),

-	builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

-

-	* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for

-	development header files.

-	Don't define PLATFORM.

-

-	* configure: Copy `modules.cfg' to builddir if builddir != srcdir.

-	Update snippet taken from autoconf's m4sh.m4 to current CVS version.

-	Be more verbose.

-

-	* include/freetype/config/ftmodule.h: Add comments -- this file is

-	no longer used if FreeType is built with GNU make.

-

-	* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,

-	docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.

-	Other minor updates.

-

-	* modules.txt: Removed.  Contents included in `modules.cfg'.

-

-

-	* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,

-	FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

-

-	* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,

-	FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)

-	[FT_STRICT_ALIASING]: Implement.

-

-2006-01-31  Chia-I Wu  <[email protected]>

-

-	* include/freetype/internal/t1types.h (AFM_FontInfo),

-	src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',

-

-	* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.

-

-	* include/freetype/freetype.h (FT_FaceRec): Mention that fields may

-	be changed after file attachment.

-

-2006-01-28  Werner Lemberg  <[email protected]>

-	* src/*/module.mk (.PHONY): Add.

-

-2006-01-27  Werner Lemberg  <[email protected]>

-

-2006-01-27  David Turner  <[email protected]>

-

-	* builds/unix/configure.ac: Fix build problem on Cygwin.

-

-	* builds/unix/install.mk (install): Don't install the internal

-	headers, and remove existing ones if found in the target install

-	directory.

-

-	* src/autofit/afwarp.c: Add simple #ifdef to prevent compilation

-	if the warp hinter isn't active (it shouldn't, still experimental).

-

-	* Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid'

-	and `otvalid' from the list of modules that are linked statically

-	to a given FreeType library.  Functionality has been moved to the

-	`ftvalid' CVS module.

-

-	Note also that current Make-based build system still compiles the

-	modules though.

-

-	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro

-	which controls the definitions of the memory management functions to

-	avoid warnings with recent versions of GCC.  This macro is only here

-	to be disabled, in case we detect problems with the new scheme.

-

-	NOTE: Disable macro to use the memory debugger -- this will be fixed

-	      later!

-

-	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,

-	FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]:

-	New versions.

-

-

-	* builds/win32/visualc/freetype.dsp: Updating project file to

-	define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from

-

-	* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,

-	FT_REQUEST_HEIGHT): New macros to get the width and height of a

-	request, in fractional pixels.

-

-	* include/freetype/internal/ftobjs.h (FT_Select_Metrics,

-	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,

-	FT_Request_Metrics): New base functions to set the font metrics.  They

-	were part of FT_Select_Size/FT_Request_Size and are made independent

-	functions so that metrics are not set again and again.

-

-	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set

-	only when driver's size_select/size_request is NULL.  That is, drivers

-	should set the metrics themselves.

-	metrics are not reliable, e.g., the sign of the descender is wrong for

-	some fonts.

-

-	tt_cmap12_char_map_binary): Fix compiler warnings.

-

-2005-11-29  Chia-I Wu  <[email protected]>

-

-	Major update to distinguish between unsorted and overlapping

-	segments for cmap format 4.  For overlapping but sorted segments,

-	which is previously considered unsorted, we still use binary search.

-

-	* src/sfnt/ttcmap.h (TT_CMapRec_): Replace `unsorted' by `flags'.

-	(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.

-

-	* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.

-	(TT_CMap4Rec_): Remove `old_charcode' and `table_length'.

-	(tt_cmap4_reset): Removed.

-	(tt_cmap4_init): Updated accordingly.

-	(tt_cmap4_next): Updated accordingly.

-	Take care of overlapping segments.

-	(tt_cmap4_validate): Make sure the subtable is large enough.

-	Do not check glyph_ids because some fonts set the length wrongly.

-	Also, if all segments have offset 0, glyph_ids is always invalid.

-	It does not cause any problem so far only because the check misses

-	equality.

-	Distinguish between unsorted and overlapping segments.

-	(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions

-	to do `charcode => glyph index' by linear/binary search.

-	(tt_cmap4_char_index, tt_cmap4_char_next): Use

-	tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.

-	(tt_face_build_cmaps): Treat the return value of validator as flags

-	for cmap.

-

-	New structures and functions for fast `next char'.

-	(tt_cmap12_char_map_binary): New function to do `charcode => glyph

-	index' by binary search.

-	(tt_cmap12_char_index, tt_cmap12_char_next): Use

-	tt_cmap12_char_map_binary.

-	(tt_face_build_cmaps): Check table and offset correctly (equality is

-	missing).

-

-	* builds/amiga/smakefile: Adjusted the compiler options

-	to the current sources, now really builds the gxvalid, gzip

-	and psnames modules.

-

-	* builds/amiga/src/base/ftsystem.c: The assumed Seek() position

-	in the file cache was off by one byte which could cause false

-	errors in font files.

-	* src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a

-	font to have no `head' table if tables `SING' and `META' are

-	present; this is to support `SING Glyphlet'.

-

-	`SING Glyphlet' is an extension to OpenType developed by Adobe

-	primarily to facilitate adding supplemental glyphs to an OpenType

-	font (with emphasis on, but not necessarily limited to, gaiji to a

-	CJK font).  A SING Glyphlet Font is an OpenType font that contains

-	the outline(s), either in a `glyf' or `CFF' table, for a glyph;

-	`cmap', `BASE', and `GSUB' tables are present with the same format

-	and functionality as a regular OpenType font; there are no `name',

-	`head', `OS/2', and `post' tables; there are two new tables, `SING'

-	which contains details about the glyphlet, and `META' which contains

-	metadata.

-

-	Further information on the SING Glyphlet format can be found at:

-

-	  https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf

-

-	* include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for

-	After long discussion, we now consider the character width vector

-	(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*

-	direction only.  For example, if you are using the horizontal

-	writing direction, you get the horizontal and vertical components of

-	the advance width for this direction.  Note that OpenType and CFF fonts

-	don't have such a vertical component; instead, the GPOS table can be

-	used to generate two-dimensional advance widths (but this isn't

-	handled by FreeType).

-

-	* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add

-	`advance_v' field to hold the vertical component of the advance

-	value.

-

-	* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c

-	(cff_slot_load), src/type1/t1gload.c

-2010-01-29  suzuki toshiya  <[email protected]>

-

-	New parameters for FT_Open_Face() to ignore preferred family names.

-

-	Preferred family names should be used for legacy systems that

-	This is Savannah patch #7059.

-

-2010-01-08  Ken Sharp  <[email protected]>

-

-	Fix Savannah bug #28521.

-

-	Issue #28226 involved a work-around for a font which used the

-	`setcurrentpoint' operator in an invalid way; this operator is only

-	supposed to be used with the result of OtherSubrs, and the font used

-	it directly.  The supplied patch removed the block of code which

-	checked this usage entirely.

-

-	This turns out to be a Bad Thing.  If `setcurrentpoint' is being

-	used correctly it should reset the flex flag in the decoder.  If we

-	don't do this then the flag never gets reset and we omit any further

-	contours from the glyph (at least until we close the path or

-	similar).

-

-	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)

-	<op_setcurrentpoint>: Handle `flex_state' correctly.

-

-	`offset_i' and `length_i'.

-

-2010-01-05  Ralph Giles  <[email protected]>

-

-	Enable the incremental font interface by default.

-

-	Ghostscript requires the incremental font interface for handling

-	some Postscript documents.  It is moving to using FreeType as its

-	primary renderer; supporting this in the default build makes it

-	Ghostscript to be linked against the system FreeType when one is

-	available.

-

-	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):

-	Uncomment.

-

-	Make Type 1 `seac' operator work with incremental interface.

-	This fixes Savannah bug #28480.

-

-	* src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'

-	if incremental interface is used.

-

-	Make incremental interface work with TrueType fonts.

-	This fixes Savannah bug #28478.

-

-	* src/truetype/ttgload.c (load_truetype_glyph): Don't check

-

-2009-12-31  Lars Abrahamsson  <[email protected]>

-

-	Make compilation with FT_CONFIG_OPTION_PIC work again.

-

-	* src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:

-	Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.

-

-	* src/base/ftinit.c (ft_destroy_default_module_classes,

-	Fix compiler warning.

-	Reported by Sean.

-

-	Fix Savannah bug #28320.

-

-	There exist corrupt, subsetted fonts (embedded in PDF files) which

-	contain a private dict that ends with an unterminated floating point

-	number (no operator following).  We now ignore this error (as

-	acrobat does).

-

-	* src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for

-	unterminated floating point numbers.

-

-2009-12-16  Werner Lemberg  <[email protected]>

-

-	Really fix compiler warnings.

-	Reported by Sean.

-

-	Improve configure.raw to copy some options from CFLAGS to LDFLAGS.

-	The linker of Mac OS X 10.6 is sensitive to the architecture.  If

-	the architectures are specified explicitly for the C compiler, the

-	linker requires the architecture specifications too.

-

-	* builds/unix/configure.raw: Replace `-isysroot' option parser by

-

-2009-12-14  Ken Sharp  <[email protected]>

-

-	Ignore invalid `setcurrentpoint' operations in Type 1 fonts.

-	This fixes Savannah bug #28226.

-

-	At least two wild PostScript files of unknown provenance contain

-	Type 1 fonts, apparently converted from TrueType fonts in earlier

-	PDF versions of the files, which use the `setcurrentpoint' operator

-	inappropriately.

-

-	FreeType currently throws an error in this case, but Ghostscript and

-	Adobe Distiller both accept the fonts and ignore the problem.  This

-	commit #ifdefs out the check so PostScript interpreters using

-	FreeType can render these files.

-

-	The specification says `setcurrentpoint' should only be used to set

-	the point after a `Subr' call, but these fonts use it to set the

-	initial point to (0,0).  Unnecessarily so, as they correctly use an

-	`hsbw' operation which implicitly sets the initial point.

-

-	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)

-	<op_setcurrentpoint>: Comment out code.

-

-2009-12-14  Bram Tassyns  <[email protected]>

-	[BDF] Modify hash API to take size_t value instead of void *.

-

-	The hash API in BDF driver is designed to be generic, it takes

-	void * typed data.  But BDF driver always gives an unsigned long

-	integer (the index to a property).  To reduce non-essential

-	casts from unsigned long to void* and from void* to unsigned

-	long, the hash API is changed to take size_t integer.

-	The issue of incompatible cast between unsigned long and void*

-	on LLP64 platform is reported by NightStrike from MinGW-Win64

-	project.  See

-	https://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

-

-	* src/bdf/bdf.h: The type of hashnode->data is changed from

-

-	Improve vertical metrics calculation (Savannah bug #27364).

-

-	The calculation of `vertBearingX' is not defined in the OTF font

-	spec so FreeType does a `best effort' attempt.  However, this value

-	is defined in the PDF and PostScript specs, and that algorithm is

-	better than the one FreeType currently uses:

-

-	  FreeType: Use the middle of the bounding box as the X coordinate

-	            of the vertical origin.

-

-	  Adobe PDF spec: Use the middle of the horizontal advance vector as

-	                  the X coordinate of the vertical origin.

-

-	FreeType's algorithm goes wrong if you have a really small glyph

-	(like the full-width, circle-like dot at the end of the sentence, as

-	used in CJK scripts) with large bearings.  With the FreeType

-	algorithm this dot gets centered on the baseline; with the PDF

-	algorithm it gets the correct location (in the top right).  Note

-	that this is a serious issue, it's like printing the dot at the end

-	of a Roman sentence at the center of the textline instead of on the

-	baseline like it should. So i believe the PDF spec's algorithm

-	should be used in FreeType as well.

-

-	The `vertBearingY' value for such small glyphs is also very strange

-	if no `vmtx' information is present, since the height of the bbox is

-	not representable for the height of the glyph visually (the

-	whitespace up to the baseline is part of the glyph).  The fix also

-	includes some code for a better estimate of `vertBearingY'.

-

-	* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'

-	is now calculated as described by the Adobe PDF Spec.  Estimate for

-	`vertBearingY' now works better for small glyphs completely above or

-	below the baseline into account.

-

-	* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now

-	calculated as described by the Adobe PDF Spec.  Vertical metrics

-	information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS

-	was not defined.

-

-	* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is

-	now calculated as described by the Adobe PDF Spec.

-	Suggested by der Mouse <[email protected]>.

-

-	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Improve

-	the check for too large glyph.  Replace the pair of `pitch' and

-	`height' by the pair of `width' and `height'.  `pitch' cannot

-

-	Use 16.16 format while parsing Type 1 charstrings.

-	This fixes Savannah bug #26867.

-

-	Previously, only integers have been used which can lead to serious

-	rounding errors.

-

-	However, fractional values are only used internally; after the

-	charstrings (of either Type 1 or 2) have been processed, the

-	resulting coordinates get rounded to integers currently -- before

-	applying scaling.  This should be fixed; at the same time a new load

-	flag should be introduced, to be used in combination with

-	FT_LOAD_NO_SCALE, which indicates that font units are returned in

-	16.16 format.  Similarly, the incremental interface should be

-	extended to allow fractional values for metrics.

-

-	* include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift'

-	field.

-	* include/freetype/internal/pshints.h (T1_Hints_SetStemFunc,

-	(t1_build_add_point): Always convert fixed to integer.

-	* src/psaux/t1decode.c (t1_decoder_parse_charstrings):

-	Use 16.16 format everywhere (except for large integers followed by a

-	`div').

-	[CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate

-	code unconditionally.

-	Add support for random numbers and update remaining code

-	accordingly; this should work now.

-	(t1operator_seac): Updated.

-	* src/psaux/pshrec.c: Include FT_INTERNAL_CALC_H.

-	(ps_hints_t1stem3, t1_hints_stem): Updated.

-

-2009-06-18  Werner Lemberg  <[email protected]>

-

-	Fix B/W rasterization of subglyphs with different drop-out modes.

-

-	Normally, the SCANMODE instruction (if present) to set the drop-out

-	mode in a TrueType font is located in the `prep' table only and thus

-	valid for all glyphs.  However, there are fonts like `pala.ttf'

-	which additionally contain this instruction in the hinting code of

-	some glyphs (but not all).  As a result it can happen that a

-	composite glyph needs multiple drop-out modes for its subglyphs

-	since the rendering state gets reset for each subglyph.

-

-	FreeType collects the hinted outlines from all subglyphs, then it

-	sends the data to the rasterizer.  It also sends the drop-out mode

-	-- after hinting has been applied -- and here is the error: It sends

-	the drop-out mode of the last subglyph only; drop-out modes of all

-	other subglyphs are lost.

-

-	This patch fixes the problem; it adds a second, alternative

-	mechanism to pass the drop-out mode: For each contour, the

-	rasterizer now checks the first `tags' array element.  If bit 2 is

-	set, bits 5-7 contain the contour's drop-out mode, overriding the

-	global drop-out mode.

-

-	* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.

-

-	* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in

-	`tags[0]'.

-

-	* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):

-	Use bits 3-5 instead of 0-2.

-	(New_Profile): Set the drop-out mode in the profile's `flags' field.

-	(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if

-	necessary.

-	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,

-	Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out

-	mode.

-

-2009-06-16  Werner Lemberg  <[email protected]>

-

-	Improve scan conversion rules 4 and 6.

-

-	Two new constraints are introduced to better identify a `stub' -- a

-	concept which is only vaguely described in the OpenType

-	specification.  The old code was too rigorous and suppressed more

-	pixel than it should.

-

-	  . The intersection of the two profiles with the scanline is less

-	    than a half pixel.  Code related to this was already present in

-	    the sources but has been commented out.

-

-	  . The endpoint of the original contour forming a profile has a

-	    distance (`overshoot') less than half a pixel to the scanline.

-

-	Note that the two additional conditions fix almost all differences

-	to the Windows rasterizer, but some problematic cases remain.

-

-	* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New

-	macros for the `flags' field in the `TProfile' structure.

-	(IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.

-	(New_Profile, End_Profile): Pass overshoot flag as an argument and

-	set it accordingly.

-	Update callers.

-	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new

-	constraints.

-

-2009-06-11  Werner Lemberg  <[email protected]>

-

-	Increase precision for B/W rasterizer.

-

-	* src/raster/ftraster.c (Set_High_Precision): Add two more bits to

-	the precision.  This corrects rendering of some small glyphs, for

-	example, glyph `xi' in verdana.ttf at 13 ppem.  Testing with ftbench

-	on my GNU/Linux box I don't see a performance degradation.

-

-	* src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.

-

-2009-03-09  Alexey Kryukov  <[email protected]>

-

-	Fix handling of EBDT formats 8 and 9 (part 2).

-

-	This patch fixes the following problems in ttsbit0.c:

-

-	. Bitmaps for compound glyphs were never allocated.

-

-	. `SBitDecoder' refused to load metrics if some other metrics have

-	  already been loaded.  This condition certainly makes no sense for

-	  recursive calls, so I've just disabled it.  Another possibility

-	  would be resetting `decoder->metrics_loaded' to false before

-	  loading each composite component.  However, we must restore the

-	  original metrics after finishing the recursion; otherwise we can

-	  get a misaligned glyph.

-

-	. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',

-	  causing some glyph components to be shifted too far to the right

-	  (especially noticeable for small sizes).

-

-	Note that support for grayscale bitmaps (not necessarily compound) is

-	completely broken in ttsbit0.c.

-

-	* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.

-	(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case

-	of `h == height'.

-	(tt_sbit_decoder_load_compound): Reset metrics after loading

-	components.

-	Allocate bitmap.

-

-	FT_USE_MODULE declares things as:

-

-	  extern const FT_Module_Class

-

-	(or similar for C++).  However, the actual types of the variables

-	being declared are often different, e.g., FT_Driver_ClassRec or

-	FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

-

-	This works with most C compilers (since those structs begin with an

-	FT_Module_Class struct), but technically it's undefined behavior.

-

-	To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7

-	paragraph 2:

-

-	  All declarations that refer to the same object or function shall

-	  have compatible type; otherwise, the behavior is undefined.

-

-	(And they are not compatible types.)

-

-	Most C compilers don't reject (or even detect!) code which has this

-	issue, but the GCC LTO development branch compiler does.  (It

-	outputs the types of the objects while generating .o files, along

-	with a bunch of other information, then compares them when doing the

-	final link-time code generation pass.)

-

-	Patch from Savannah bug #25133.

-

-	* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

-

-	* builds/amiga/include/freetype/config/ftmodule.h,

-2008-12-10  Werner Lemberg  <[email protected]>

-

-	Generalize the concept of `tricky' fonts by introducing

-	FT_FACE_FLAG_TRICKY to indicate that the font format's hinting

-	engine is necessary for correct rendering.

-

-	At the same time, slightly modify the behaviour of tricky fonts:

-	FT_LOAD_NO_HINTING is now ignored.  To really force raw loading

-	of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and

-	FT_LOAD_NO_AUTOHINT must be used.

-

-	Finally, tricky TrueType fonts always use the bytecode interpreter

-	even if the patented code is used.

-

-	* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):

-	New macros.

-

-	* src/truetype/ttdriver.c (Load_Glyph): Handle new load flags

-	semantics as described above.

-	* src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky

-	fonts.

-

-	* docs/CHANGES: Document it.

-2008-12-09  Werner Lemberg  <[email protected]>

-

-	Really fix Savannah bug #25010: An SFNT font with neither outlines

-	nor bitmaps can be considered as containing space `glyphs' only.

-

-	* src/truetype/ttpload.c (tt_face_load_loca): Handle the case where

-	a `glyf' table is missing.

-

-	* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no

-	`glyf' table but a non-zero `loca' entry.

-	(tt_loader_init): Handle missing `glyf' table.

-

-	* src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.

-

-2008-11-29  James Cloos  <[email protected]>

-

-	* src/type1/t1load.c (mm_axis_unmap): `blend_points' is FT_Fixed*,

-	whereas `design_points' is FT_Long*.  Therefore, return blend rather

-	than design points.

-2008-10-02  suzuki toshiya  <[email protected]>

-

-	* src/base/ftbase.h: New file to declare the private utility

-	share between ftobjs.c and ftmac.c.

-

-	* src/base/rule.mk: Add ftbase.h.

-	* src/base/rules.mk: Add conditional source to BASE_SRC, for `make

-	multi' on Mac OS X.  If the macro $(ftmac_c) is defined,

-

-	* src/smooth/ftgrays.c (gray_raster_render): Don't dereference

-	`target_map' if FT_RASTER_FLAG_DIRECT is set.  Problem reported by

-	Stephan T. Lavavej <[email protected]>.

-

-2008-09-21  suzuki toshiya  <[email protected]>

-

-	jam.

-

-2008-09-20  Werner Lemberg  <[email protected]>

-

-	* src/smooth/ftgrays.c (gray_find_cell): Fix threshold.  The values

-	passed to this function are already `normalized'.  Problem reported

-	by Stephan T. Lavavej <[email protected]>.

-

-	* docs/CHANGES: Document it.

-

-2008-09-20  Werner Lemberg  <[email protected]>

-

-	CID-keyed font support.

-	* builds/mac/ftmac.c: Ditto.

-

-2008-09-19  suzuki toshiya  <[email protected]>

-

-	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in

-	sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.

-	`open_face_from_buffer' frees the passed buffer if it cannot open a

-	face from the buffer, so the caller must not free it.

-

-2008-09-19  suzuki toshiya  <[email protected]>

-

-	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support

-	for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.

-	Type1 and sfnt-wrapped CID-keyed font support.

-

-2008-09-18  Werner Lemberg  <[email protected]>

-

-	* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for

-	orthogonality (ft_free and ft_sfree could belong to different memory

-	pools).  This fixes Savannah bug #24297.

-

-2008-09-18  suzuki toshiya  <[email protected]>

-

-	* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined

-

-2008-09-16  Werner Lemberg  <[email protected]>

-

-	* src/cff/cffgload.h, src/cff/cffgload.c

-	of default values.

-

-2008-09-15  Werner Lemberg  <[email protected]>

-

-	* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'

-	and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to

-	prevent unconditional definition.  This fixes Savannah bug #24241.

-

-	* src/psnames/pstables.h: Regenerated.

-

-2008-09-13  Werner Lemberg  <[email protected]>

-

-	* autogen.sh, builds/unix/configure.raw,

-	include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor

-	beautifying.

-

-	* include/freetype/ftadvanc.h, include/freetype/ftgasp.h,

-	include/freetype/ftlcdfil.h: Protect against FreeType 1.

-	Some other minor fixes.

-

-

-2008-09-11  Werner Lemberg  <[email protected]>

-

-	* src/base/ftbase.c: Include ftadvanc.c.

-

-2008-09-11  suzuki toshiya  <[email protected]>

-

-	* builds/unix/ftconfig.in: Duplicate the cpp computation of

-	FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.

-	(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp

-	computation is disabled and the statically configured sizes are

-	used.  This fixes Savannah bug #21250.

-

-	* builds/unix/configure.raw: Add the checks to compare the cpp

-	computation results of the bit length of int and long versus the

-	sizes detected by running `configure'.  If the results are

-	different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the

-	results.

-	New option --{enable|disable}-biarch-config is added to define or

-	undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.

-

-2008-09-05  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or

-	ApplicationServices framework is missing.  Although this value is not

-	used in building of FreeType2, it is written in `freetype2.pc' and

-	`freetype-config'.

-

-2008-09-01  David Turner  <[email protected]>

-

-	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap

-	index to mean `use default cached FT_Face's charmap'.  This fixes

-	Savannah bug #22625.

-	* include/freetype/ftcache.h: Document it.

-

-

-	Make FT_MulFix an inlined function.  This is done to speed up

-	FreeType a little (on x86 3% when loading+hinting, 10% when

-	rendering, ARM savings are more important though).  Disable this by

-	undefining FT_CONFIG_OPTION_INLINE_MULFIX.

-

-	Use of assembler code can now be controlled with

-	FT_CONFIG_OPTION_NO_ASSEMBLER.

-

-	* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in

-	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler

-	implementation.

-	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler

-	implementation taken from `ftcalc.c'.

-	which is defined to the platform-specific assembler implementation

-	of FT_MulFix.

-	[FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]

-	(FT_MULFIX_INLINED): New macro.

-

-	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,

-	FT_CONFIG_OPTION_INLINE_MULFIX): New macros.

-

-	* include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.

-

-	* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and

-	FT_MULFIX_INLINED.

-

-

-	Add a new header named FT_ADVANCES_H declaring some new APIs to

-	extract the advances of one or more glyphs without necessarily

-	loading their outlines.  Also provide `fast loaders' for the

-	TrueType, Type1, and CFF font drivers (more to come later).

-

-	* src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.

-

-	* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.

-	* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.

-

-	* include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):

-	`flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',

-	respectively.

-

-	* src/truetype/ttdriver.c (tt_get_advances): New function.

-	(tt_driver_class): Register it.

-

-	* src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...

-	(TT_Get_HMetrics, TT_Get_VMetrics): This.

-	Update callers.

-	* src/truetype/ttgload.h: Declare them.

-

-	* src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New

-	function.

-

-

-	Add checks for minimum version of the `autotools' stuff.

-

-	* autogen.sh: Implement it.

-	(get_major_version, get_minor_version, get_patch_version,

-	compare_to_minimum_version, check_tool_version): New auxiliary

-	functions.

-

-	* README.CVS: Document it.

-

-2008-08-29  suzuki toshiya  <[email protected]>

-

-	* src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in

-	tttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).

-

-2008-08-28  Werner Lemberg  <[email protected]>

-

-	* src/type1/t1load.c (parse_encoding): Protect against infinite

-	loop.  This fixes Savannah bug #24150 (where a patch has been posted

-	too).

-

-2008-08-23  Werner Lemberg  <[email protected]>

-

-	* src/type/t1afm.c (compare_kern_pairs), src/psaux/afmparse.c

-	#24119.

-

-2008-08-19  suzuki toshiya  <[email protected]>

-

-	* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,

-	even if passed library or arguments are invalid.  This fixes a bug

-	that an uninitialized stream is freed when an invalid library handle

-	is passed.  Originally proposed by Mike Fabian, 2008/08/18 on

-	freetype-devel.

-	(FT_Open_Face): Ditto (stream).

-	(load_face_in_embedded_rfork): Ditto (stream2).

-

-2008-08-18  suzuki toshiya  <[email protected]>

-

-	* src/base/ftmac.c: Add a fallback to guess the availability of the

-	`ResourceIndex' type.  It is used when built without configure

-	(e.g., a build with Jam).

-	* builds/mac/ftmac.c: Ditto.

-	* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0

-	explicitly, even if `ResourceIndex' is unavailable.

-

-2008-08-18  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.raw: In checking of Mac OS X features,

-	all-in-one header file `Carbon.h' is replaced by the minimum

-	header file `CoreServices.h', similar to current src/base/ftmac.c.

-

-2008-08-18  suzuki toshiya  <[email protected]>

-

-	* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of

-	sub-header when its code_count is 0.  Many Japanese Dynalab fonts

-	include such an empty sub-header (code_count == 0, first_code == 0

-	delta == 0, but offset != 0) as the second sub-header in SJIS cmap.

-

-2008-08-04  Werner Lemberg  <[email protected]>

-

-	* src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes

-	Savannah bug #23995.

-

-	* src/cid/cidload.c (parse_expansion_factor): New callback function.

-	(cid_field_records): Use it for `ExpansionFactor'.

-	* src/cod/cidtoken.h: Handle `ForceBold' keyword.

-	Don't handle `ExpansionFactor'.

-

-2008-08-04  Bram Tassyns  <[email protected]>

-

-	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which

-	resulted in incorrect scaling.  This fixes Savannah bug #23973.

-

-2008-08-04  Werner Lemberg  <[email protected]>

-

-	Be more tolerant w.r.t. invalid entries in SFNT table directory.

-

-	* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and

-	adjust table count.

-	Add more trace messages.

-	(tt_face_load_font_dir): Updated.

-

-2008-07-30  Werner Lemberg  <[email protected]>

-

-	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer

-	assume that the first argument on the stack is the bottom-most

-	element.  Two reasons:

-

-	  o According to people from Adobe it is missing in the Type 2

-	    specification that pushing of additional, superfluous arguments

-	    on the stack is prohibited.

-

-	  o Acroread in general handles fonts differently, namely by popping

-	    the number of arguments needed for a particular operand (as a PS

-	    interpreter would do).  In case of buggy fonts this causes a

-	    different interpretation which of the elements on the stack are

-	    superfluous and which not.

-

-	Since there are CFF subfonts (embedded in PDFs) which rely on

-	Acroread's behaviour, FreeType now does the same.

-

-2008-07-27  Werner Lemberg  <[email protected]>

-

-	Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This

-	fixes Savannah bug #23940.

-

-	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...

-	(EXTRA_GLYPH_LIST_SIZE): This.

-	Increase by 2.

-	(ft_wgl_extra_unicodes): Rename to...

-	(ft_extra_glyph_unicodes): This.

-	Add two code values.

-	(ft_wgl_extra_glyph_names): Rename to...

-	Add two glyphs.

-	(ft_wgl_extra_glyph_name_offsets): Rename to...

-	(ft_extra_glyph_name_offsets): This.

-	Add two offsets.

-

-	(ps_check_wgl_name, ps_check_wgl_unicode): Rename to...

-	(ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.

-	Updated.

-	(ps_unicodes_init): Updated.

-

-2008-07-26  Werner Lemberg  <[email protected]>

-

-	* src/cff/cffgload.c (cff_decoder_prepare,

-	cff_decoder_parse_charstrings): Improve debug output.

-

-2008-07-22  Martin McBride  <[email protected]>

-

-	* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,

-	tt_cmap4_char_map_binary): Handle fonts which treat the last segment

-	specially.  According to the specification, such fonts would be

-	invalid but acroread accepts them.

-

-2008-07-16  Jon Foster  <[email protected]>

-

-	* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

-2008-07-16  Werner Lemberg  <[email protected]>

-

-	Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.

-	Invert sids table only if `pure_cff' is set.

-	* src/cff/cffload.h: Updated.

-

-	* src/cff/cffobjs.c (cff_face_init): Updated.

-	Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.

-	* docs/CHANGES: Updated.

-

-2008-07-09  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts

-	where num_locations < num_glyphs.  Problem reported by Ding Li.

-

-2008-07-05  Werner Lemberg  <[email protected]>

-

-	Since FreeType uses `$(value ...)', we now need GNU make 3.80 or

-	newer.  This fixes Savannah bug #23648.

-

-	* configure: zsh doesn't like ${1+"$@"}.

-	Update needed GNU make version.

-	* builds/toplevel.mk: Check for `$(eval ...)'.

-	* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document

-	it.

-

-2008-07-04  Werner Lemberg  <[email protected]>

-

-	* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one

-	pixel, only check for dropouts if neither start nor end point lies

-	on a pixel center.  This fixes Savannah bug #23762.

-

-2008-06-29  Werner Lemberg  <[email protected]>

-

-	* Version 2.3.7 released.

-	=========================

-

-

-	Tag sources with `VER-2-3-7'.

-

-	* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump

-	version number to 2.3.7.

-

-	builds/win32/visualce/index.html,

-	builds/win32/visualce/freetype.dsp,

-	builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.

-

-	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.

-

-	* builds/unix/configure.raw (version_info): Set to 9:18:3.

-

-	* docs/release: Updated.

-

-2008-06-28  Werner Lemberg  <[email protected]>

-

-	* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...

-	* src/ftcalc.c: Here.  This fixes Savannah bug #23729.

-

-2008-06-27  Werner Lemberg  <[email protected]>

-

-	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,

-	Horizontal_Gray_Sweep_Drop): Test for intersections which

-	degenerate to a single point can be ignored; this has been confirmed

-	by Greg Hitchcock from Microsoft.  (This was commented out code.)

-

-2008-06-26  Werner Lemberg  <[email protected]>

-

-	Improve navigation in API reference.

-

-	* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...

-	(html_header_6): This.

-	(html_header_3, html_header_3i, html_header_4, html_header_5,

-	html_header_5t): New strings.

-	(toc_footer_start, toc_footer_end): New strings.

-	(HtmlFormatter::html_header): Updated.

-	(HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):

-	New strings.

-	(HtmlFormatter::index_enter): Use `html_index_header'.

-	(HtmlFormatter::toc_enter): Use `html_toc_header'.

-	(HtmlFormatter::toc_exit): Print proper footer.

-

-	Convert ~ to non-breakable space.

-

-	* src/tools/docmaker/tohtml.py (make_html_para): Implement it.

-	Update header files accordingly.

-

-2008-06-24  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.raw: Check type `ResourceIndex' explicitly

-	and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5

-	bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without

-	ResourceIndex type definition.  The macro does not inform the type

-	availability.

-	* src/base/ftmac.c: More parentheses are inserted to clarify the

-	conditionals to disable legacy APIs in `10.5 and later' cases.  If

-	HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.

-

-2008-06-24  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering

-	mode.

-

-	* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,

-	Draw_Sweep): No-dropout mode is value 2, not value 0.

-	(Draw_Sweep): Really skip dropout handling for no-dropout mode.

-

-2008-06-24  Werner Lemberg  <[email protected]>

-

-	* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour

-	if it consists of one point only.  Based on a patch from Savannah

-	bug #23683 (from John Tytgat).

-

-2008-06-22  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff

-	with IS_HINTED.

-

-	* docs/CHANGES: Updated.

-

-2008-06-22  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option

-	but LDFLAGS does not, import it to LDFLAGS.  The option is used to

-	specify non-default SDK on Mac OS X (e.g., universal binary SDK for

-	Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137

-	recommends to add the option only to CFLAGS, LDFLAGS should include

-	it because libfreetype.la is built with -no-undefined.  This fixes a

-	bug reported by Ryan Schmidt in MacPorts,

-	https://trac.macports.org/ticket/15331.

-

-2008-06-21  Werner Lemberg  <[email protected]>

-

-	Enable access to the various dropout rules of the B&W rasterizer.

-	Pass dropout rules from the TT bytecode interpreter to the

-	rasterizer.

-

-	FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.

-

-	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,

-	Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the

-	OpenType specification.

-	Fix mode 4 computation.

-	(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

-

-	* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion

-	mode to FT_OUTLINE_XXX flags.

-

-	* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

-

-2008-06-19  Werner Lemberg  <[email protected]>

-

-	* src/cff/cffobjs.c (cff_face_init): Compute final

-	`dict->units_per_em' value before assigning it to

-	`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are

-	scaled incorrectly if the font matrix is non-standard.  This fixes

-	Savannah bug #23630.

-

-2008-06-06  Werner Lemberg  <[email protected]>

-

-	correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.

-

-2008-06-03  Werner Lemberg  <[email protected]>

-

-	* include/freetype/ftcache.h (FTC_FaceID): Change type back to

-2008-05-20  suzuki toshiya  <[email protected]>

-

-	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

-

-2008-05-18  Werner Lemberg  <[email protected]>

-

-	* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after

-	correction for pixel boundary.  Without this patch, the effect can

-	be cumulative under certain circumstances, making glyphs taller and

-	taller after each call.  This fixes Savannah bug #19976.

-

-2008-05-18  Werner Lemberg  <[email protected]>

-

-	* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

-2008-05-15  Werner Lemberg  <[email protected]>

-

-	* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.

-2008-05-15  Werner Lemberg  <[email protected]>

-

-	* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array

-	which contains a single but empty entry.  This is technically

-	invalid (since it must end with `return'), but...

-

-	Reported by Martin McBride.

-	code from `cff_size_init'.

-	(cff_size_init, cff_size_done, cff_size_select, cff_size_request):

-	Use CFF_Internal and handle subfonts.

-	(cff_face_init): Handle top-dict and subfont matrices correctly;

-	apply some heuristic in case of unlikely matrix concatenation

-	results.  This has been discussed with people from Adobe (thanks

-	goes mainly to David Lemon) who confirm that the CFF specs are fuzzy

-	(cff_parse_fixed_scaled): This function.  Update all callers.

-

-2008-05-03  Werner Lemberg  <[email protected]>

-

-	* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without

-

-	* builds/symbian/*: New files.

-

-2008-02-21  suzuki toshiya  <[email protected]>

-

-	* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name

-	synthesis.  For any face of a specified FOND, always the name for

-	the first face was used.  Except of a FOND that refers multiple

-	Type1 font files, wrong synthesized font names are not used at all,

-	so this is an invisible bug.  A few limit checks are added too.

-

-	* builds/mac/ftmac.c: Ditto.

-

-2008-02-21  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.raw: Split compiler option to link Carbon

-	frameworks to one option for CoreServices framework and another

-	option for ApplicationServices framework.  The split options can be

-	managed by GNU libtool to avoid unrequired duplication when FreeType

-	Savannah bug #22366.

-

-2008-02-18  Victor Stinner  <[email protected]>

-

-	Check for valid callback pointers.

-

-2008-02-15  suzuki toshiya  <[email protected]>

-

-	* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource

-	handle by its value instead of ResError(), fix provided by Deron

-	Kazmaier.  According to the Resource Manager Reference,

-	GetResource(), Get1Resource(), GetNamedResource(),

-	Get1NamedResource() and RGetResource() set noErr but return NULL

-	handle when they can not find the requested resource.  These

-	functions never return undefined values, so it is sufficient to

-	check if the handle is not NULL.

-

-	* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.

-

-2008-02-14  suzuki toshiya  <[email protected]>

-

-	* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other

-	inclusion styles.  Now it always includes src/base/ftmac.c;

-	builds/mac/ftmac.c is never included in any configuration.

-

-	* builds/unix/configure.raw: Print warning if configure is executed

-	with options to specify Carbon functionalities explicitly.

-

-	* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not

-	included automatically and manual replacement is required.

-

-2008-02-11  Werner Lemberg  <[email protected]>

-

-	* builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk

-	(dos_setup), builds/freetype.mk (clean_project_dos,

-	distclean_project_dos): Don't use \ but $(SEP).  Reported by Duncan

-	Murdoch.

-

-	* src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to

-	mention intra-pixel algorithm.

-

-	* include/freetype/freetype.h (FT_Render_Mode): Mention that

-	FT_Library_SetLcdFilter can be used to reduce fringes.

-

-2008-01-16  Werner Lemberg  <[email protected]>

-

-2008-01-10  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttgload.c (load_truetype_glyph): Handle the case

-	where the number of contours in a simple glyph is zero (and which

-	does contain an entry in the `glyf' table).  This fixes Savannah bug

-	#21990.

-

-2008-01-04  suzuki toshiya  <[email protected]>

-

-	Formatting suggested by Sean McBride.

-

-	* builds/mac/ftmac.c: Formatting (tab expanded).

-2007-12-30  Werner Lemberg  <[email protected]>

-

-	* src/smooth/ftgrays.c (gray_raster_render): Check `outline'

-	correctly.

-

-2007-12-21  suzuki toshiya  <[email protected]>

-

-	Improvement of POSIX resource-fork accessor to load unsorted

-	references in a resource.  In HelveLTMM (resource-fork PostScript

-	Type1 font bundled with Mac OS X since 10.3.x), the appearance order

-	of PFB chunks is not sorted; sorting the chunks by reference IDs is

-	required.

-

-	* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure

-	type to store a pair of reference ID and offset to the chunk.

-

-	* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to

-

-2007-12-14  Werner Lemberg  <[email protected]>

-

-	* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'

-	division too early; otherwise the most significant digit(s) of the

-	final result are lost as the value is truncated to an integer.  This

-	fixes Savannah bug #21794 (where the patch has been posted too).

-

-2007-12-06  Fix  <[email protected]>

-

-	Pass options from one configure script to another as-is (not

-	expanded).  This is needed for options like

-	--includedir='${prefix}/include'.

-

-	* builds/unix/detect.mk, configure: Prevent argument expansion in

-	call to the (real) `configure' script.

-

-2007-12-06  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if

-	TT_USE_BYTECODE_INTERPRETER isn't defined.

-

-2007-12-06  Werner Lemberg  <[email protected]>

-

-	There exist CFFs which contain opcodes for the Type 1 operators

-	`hsbw' and `closepath' which are both invalid in Type 2 charstrings.

-	However, it doesn't harm to support them.

-

-	* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and

-	`cff_op_closepath.'

-	(cff_argument_counts): Ditto.

-

-	(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)

-

-	* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to

-	case-sensitive HFS+.

-	(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of

-	buffer size to store a pathname.

-	* include/freetype/internal/ftrfork.h: Increment the number of

-	The documents and comments for Mac OS X are improved by Sean

-	McBride.

-

-	* src/base/ftmac.c: Fix a comment.

-

-	Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is

-	not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()

-	cannot mmap() the specified file and cannot seek to head of the

-	specified file, it returns NULL stream and FT_Open_New() returns the

-	error immediately.  On MacOS, most legacy MacOS fonts fall into such

-	a scenario because their data forks are zero-sized and cannot be

-	sought.  To proceed to guessing of resource fork fonts, the

-	functions for legacy MacOS font must properly handle the NULL stream

-	returned by FT_New_Stream().

-

-	* src/base/ftobjs.c (IsMacBinary): Return error

-	FT_Err_Invalid_Stream_Operation immediately when NULL stream is

-	passed.

-	(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed

-	to fallback.  Originally, legacy MacOS font is tested in the cases

-	of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)

-	or FT_Err_Unknown_File_Format (occurs when AppleSingle header or

-	.dfont header is combined).  Now the case of

-	FT_Err_Cannot_Open_Stream is included.

-

-	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,

-	skip FT_Stream_Seek(), which seeks to the head of stream, and

-	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()

-	for a NULL stream causes a Bus error on Mac OS X.

-	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream

-	immediately if passed stream is NULL.

-	(raccess_guess_apple_single): Ditto.

-

-2007-11-16  suzuki toshiya  <[email protected]>

-

-	Fix for Carbon incompatibilities since Mac OS X 10.5,

-	proposed by Sean McBride.

-

-	* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.

-

-	* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and

-	FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling

-	Carbon functions from a forked process is classified as unsafe

-	by Apple.  All Carbon-dependent functions should be deprecated.

-

-	* src/base/ftmac.c: Use essential header files

-	<CoreServices/CoreServices.h> and

-	<ApplicationServices/ApplicationServices.h> instead of

-	all-in-one header file <Carbon/Carbon.h>.

-

-	Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple

-	genuine macro PATH_MAX.

-

-	Add fallback macro for kATSOptionFlagsUnRestrictedScope which

-	is not found in Mac OS X 10.0.

-

-	Multi-character constants ('POST', 'sfnt' etc) are replaced by

-	64bit constants calculated by FT_MAKE_TAG() macro.

-

-	For the index in the segment of resource fork, new portable

-	type ResourceIndex is introduced for better compatibility.

-	This type is since Mac OS X 10.5, so it is defined as short

-	when built on older platforms.

-

-	(FT_ATSFontGetFileReference): If build target is only the systems

-	10.5 and newer, it calls Apple genuine ATSFontGetFileReference().

-

-	(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5

-	and newer or 64bit platform, because legacy type FSSpec type is

-	removed completely.

-

-	(FT_New_Face_From_FSSpec): Ditto.

-

-2007-11-01  Werner Lemberg  <[email protected]>

-

-	* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This

-	fixes Savannah bug #21485.

-

-2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>

-

-	* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver

-	can handle the font at all, then check `face_index'.  Otherwise, the

-	driver might return the wrong error code.  This fixes Savannah bug

-	#21468.

-

-2007-10-21  Werner Lemberg  <[email protected]>

-

-	* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare

-	support for bit 8 of the `fsSelection' field in the `OS/2' table.

-	MS is already using this; hopefully, this becomes part of OpenType

-	1.5.

-	Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22

-	(WWS_SUBFAMILY).

-

-2007-10-20  Werner Lemberg  <[email protected]>

-

-	* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.

-	Add `td.left' element to CSS.

-

-	* include/freetype/freetype.h, src/base/ftobjs.c: Rename API

-	  FT_Get_Char_Variant_Index     -> FT_Face_GetCharVariantIndex

-	  FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault

-

-	* src/sfnt/ttcmap.c: Stronger cmap 14 validation.

-	conventions and modify the cmap14 functions that returned a newly

-	allocated array to use a persistent vector from the TT_CMap14 object

-	instead.

-

-	(TT_CMap14Rec): Provide array and auxiliary data for result.

-	* builds/unix/configure.raw (version_info): Set to 9:12:3.

-

-

-	* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c

-	(af_loader_load_g): Disable the warper (i.e., the light hinting

-	improvements) to make a 2.3.1 bugfix release before introducing a

-	new feature.  This should give us more time to tune and improve the

-	warper for the next release.

-

-	* docs/CHANGES: Update accordingly.

-

-2007-01-25  David Turner  <[email protected]>

-

-	For light auto-hinting, improve glyph advance widths and resurrect

-	normal/full hinting to its normal quality.

-

-	* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'

-	and `xmax_delta'.

-	correctly in a sanity check.  Since this function is only used to

-	load local and global functions, any charstring that called the last

-	local/global function would fail otherwise.  This fixes Savannah bug

-	#18867.

-

-	* docs/CHANGES: Document it.

-

-2007-01-23  David Turner  <[email protected]>

-

-	* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that

-	prevented compilation when disabling both the unpatented and the

-	bytecode interpreter in the TrueType font driver.

-

-	which happens when FT_Done_Library is called with still opened

-	CFF_Faces in it.  We need to close all faces before destroying the

-

-

-	Add a new API to support color filtering of subpixel glyph bitmaps.

-	LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING

-	isn't defined at compile time.  This only changes the content of the

-	rendered glyph to match the one of normal gray-level rendering,

-	hence clients should not need to be modified.

-

-	* docs/CHANGES: Updated.

-

-2006-09-18  Garrick Meeker  <[email protected]>

-	themselves and the auto-fitter module.

-

-	We now use inline assembler code with GCC to implement `FT_MulFix',

-	which is probably the most important function related to the

-	engine's performance.

-

-	The resulting speed-up is about 25%.

-

-

-	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields

-	`cursor' and `limit'.

-

-	* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):

-	New functions.

-	(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.

-	[TEST]: Remove.

-

-	* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test

-	code.

-

-	* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call

-	`FT_ZERO'

-	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.

-	(af_glyph_hints_reload: Rewrite recognition of weak points.

-

-	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move

-	constant values out of the loops.

-

-	* src/autofit/aftypes.h: Updated.

-

-	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

-

-	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector

-	product to get orientation.

-

-	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.

-	(FT_Stream_OpenGzip): Use it to handle small files directly in

-	memory.

-

-	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode):

-	Improve performance.

-

-	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and

-	`limit'.

-

-	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,

-	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against

-	exceedingly large values of number of contours.  Speed up by

-	reducing the number of loops.

-

-	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.

-

-

-	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold

-	used to detect rogue clients from 4 to 16.  This is to prevent some

-	segmentation faults with fonts like `KozMinProVI-Regular.otf' which

-	comes from the Japanese Adobe Reader Asian Font pack.

-

-2007-05-17  Werner Lemberg  <[email protected]>

-

-	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This

-	fixes the first part of Savannah bug #16590.

-

-2006-05-16  Werner Lemberg  <[email protected]>

-

-	* docs/PROBLEMS: Updated icl issues.

-

-	[cff] Make Adobe CFF engine work correctly on 64bit hosts.

-

-	Reported by numerous people on the `freetype-devel' list.  Without

-	this fix, glyphs aren't properly aligned on a common baseline.

-

-	On 64bit systems, `FT_Pos' expands to `long int', having a width of

-	64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on

-	64bit hosts also.  Wrong casts filled up the blues arrays with

-	incorrect values.  Note that all blues values are accessed with the

-	`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.

-

-	* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,

-	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for

-	`data', not `CF2_Fixed'.

-	* src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,

-	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.

-	* src/cff/cf2blues.c (cf2_blues_init): Updated.

-

-	More fixes for clang's `sanitize' feature.

-

-	* src/base/ftcalc.c (FT_DivFix): Use unsigned values for

-	computations which use the left shift operator and convert to signed

-	as the last step.

-	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,

-	unused.

-

-	* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,

-	as the last step.

-	Use proper types in tracing messages.

-2013-04-13  Werner Lemberg  <[email protected]>

-

-	[cff] Add a new Type 2 interpreter and hinter.

-

-	This work, written by Dave Arnold <[email protected]> and fully

-	integrated into FreeType by me, is a donation by Adobe in

-	collaboration with Google.  It is vastly superior to the old CFF

-	engine, and it will replace it soon.  Right now, it is still off by

-	default, and you have to explicitly select it using the new

-	`hinting-engine' property of the cff driver.

-

-	For convenience, (most of) the new files are committed separately.

-

-	* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.

-	* include/freetype/ftcffdrv.h: New file to access CFF driver

-	properties.

-	* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error

-	code.

-	* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',

-	and `cf2interp'.

-

-	* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.

-	* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'

-	and `no_stem_darkening'.

-	* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.

-

-	* src/cff/cff.c: Include new files.

-	* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle

-	`hinting-engine' and `no-stem-darkening' properties (only the Adobe

-	engine listens to them).

-	* src/cff/cffgload.c: Include `cf2ft.h'.

-	(cff_decoder_prepare): Initialize `current_subfont'.

-	(cff_build_add_point): Handle Adobe engine which uses 16.16

-	coordinates.

-	(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING

-	separately.

-	Choose rendering engine based on `hinting_engine' property.

-	* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe

-	engine.

-	* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.

-	(cff_driver_init): Set default property values.

-

-	* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.

-

-	* src/cff/cf2*.*: New files, containing the Adobe engine.

-

-2013-04-12  Werner Lemberg  <[email protected]>

-

-	[cff] Minor code administration issues.

-

-	* src/cff/cffgload.c (check_points): Rename to...

-	(cff_check_points): ...this and make it FT_LOCAL.

-	(cff_builder_add_point, cff_builder_add_point1,

-	cff_builder_start_point, cff_builder_close_contour,

-	cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data,

-	cff_free_glyph_data): Make them FT_LOCAL.

-

-	* src/cff/cffgload.h: Updated.

-

-2013-04-12  Werner Lemberg  <[email protected]>

-

-	Add output bitmap checksums.

-

-	Use `FT2_DEBUG=bitmap:3' for tracing.

-

-	* src/base/md5.c, src/base/md5.h: New files, taken from

-

-	  https://openwall.info/wiki/people/solar/software/public-domain-source-code/md5

-

-	* include/freetype/internal/fttrace.h: Add `bitmap'.

-

-	* src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'

-

-	(FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,

-	convert resulting bitmap to a uniform format and compute a checksum.

-	Use `bitmap' category for the tracing message.

-

-

-	* docs/LICENSE.TXT: Updated.

-

-2013-04-12  Werner Lemberg  <[email protected]>

-

-	[cff] Add framework for CFF properties.

-

-	* include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7):

-	New macro.

-

-	* src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H.

-	(cff_property_set, cff_property_get): New functions, still empty.

-	Define `cff_service_properties' service.

-	Update `cff_services'.

-

-	* src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.

-	(CFF_SERVICE_PROPERTIES_GET): New macro.

-	(CffModulePIC): Add `cff_service_properties'.

-

-2013-04-03  Werner Lemberg  <[email protected]>

-

-	[bdf] Fix Savannah bug #38589.

-

-	* src/bdf/bdflib.c (_bdf_readstream): Thinko.

-

-2013-03-31  Werner Lemberg  <[email protected]>

-

-	* configure: Use egrep, not grep.

-

-	Problem reported Mojca Miklavec <[email protected]>.

-

-2013-03-29  Werner Lemberg  <[email protected]>

-

-	* include/freetype/ftlcdfil.h: Add description of color filtering.

-

-	Based on a contribution from Antti S. Lankila <[email protected]>

-	(Savannah bug #38607).

-

-2013-03-23  Werner Lemberg  <[email protected]>

-

-	[autofit] Minor.

-

-	* src/autofit/afmodule.c (af_property_set): Typo.

-	(af_autofitter_init, af_autofitter_done): Use cast.

-

-2013-03-21  Werner Lemberg  <[email protected]>

-

-	* configure: Automatically test for `gmake' also.

-

-	Suggested by Mojca Miklavec <[email protected]>.

-

-2013-03-21  Peter Breitenlohner  <[email protected]>

-

-	Respect CONFIG_SHELL from the environment.

-

-	Some large packages using FreeType have to use a broken (deficient)

-	/bin/sh.  The configure scripts (as generated by Autoconf) are

-	clever enough to find a better shell and put that one into the

-	environment variable CONFIG_SHELL.  If that environment variable is

-	already set the script skips the test and assumes to be already

-	running under a good shell.

-

-	* builds/unix/detect.mk: Honour CONFIG_SHELL.

-	* builds/unix/unix-def.in (SHELL): Define.

-

-2013-03-21  Werner Lemberg  <[email protected]>

-

-	Fix Savannah patch #7971.

-

-	* configure: Handle MAKE environment variable also.

-

-2013-03-17  Werner Lemberg  <[email protected]>

-

-	Fix Savannah bug #38538.

-

-	* builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,

-	builds/wince/ftdebug.c (FT_Throw): Add function.

-

-2013-03-17  Werner Lemberg  <[email protected]>

-

-	[raster] Remove dead code.

-

-	* src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)

-	src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.

-

-2013-03-17  Werner Lemberg  <[email protected]>

-

-	* src/pshinter/pshpic.h (GET_PIC): Use correct container.

-

-2013-03-15  Werner Lemberg  <[email protected]>

-

-	* include/freetype/ftmoderr.h: Fix commit from 2013-03-11.

-

-	The previous version was not backward compatible.  Reported by

-	Behdad.

-

-2013-03-14  Werner Lemberg  <[email protected]>

-

-	*/*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.

-

-	FT_Err_XXX and friends are no longer directly used in the source

-	code.

-

-2013-03-14  Werner Lemberg  <[email protected]>

-

-	New error management macros.

-

-	* include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...

-	* include/freetype/fttypes.h: ... this file.

-	(FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New

-	macros.

-

-	* include/freetype/freetype.h: Updated.

-

-2013-03-14  Werner Lemberg  <[email protected]>

-

-	*/*: Use FT_Err_Ok only.

-

-	This is a purely mechanical conversion.

-

-2013-03-14  Werner Lemberg  <[email protected]>

-

-	*/*: Use `FT_THROW'.

-

-	This is essentially a mechanical conversion, adding inclusion of

-	`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for

-	stand-alone compiling modes of the rasterizer modules.

-

-	To convert the remaining occurrences of FT_Err_XXX and friends it is

-	necessary to rewrite the code.  Note, however, that it doesn't harm

-	if some cases are not handled since FT_THROW is a no-op.

-

-2013-03-13  Werner Lemberg  <[email protected]>

-

-	Introduce `FT_THROW' macro.

-

-	The idea is to replace code like

-

-	  return FT_Err_Foo_Bar;

-

-	or

-

-	  return CFF_Err_Foo_Bar;

-

-	with

-

-	  return FT_THROW( Foo_Bar );

-

-	The FT_THROW macro has two functions:

-

-	  . It hides the module specific prefix.

-

-	  . In debug mode, it calls the empty function `FT_Throw' which can

-	    be thus used to set a breakpoint.

-

-	* include/freetype/internal/ftdebug.h (FT_THROW): New macro.

-	(FT_Throw): New prototype.

-	* src/base/ftdebug.c (FT_Throw): New function.

-

-2013-03-12  Werner Lemberg  <[email protected]>

-

-	Remove `FT_KEEP_ERR_PREFIX'.

-

-	The idea is to always have FT_ERR_PREFIX available internally.

-

-	* include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard

-	undefinition of FT_ERR_PREFIX

-

-	* src/gxvalid/gxverror.h, src/otvalid/otverror.h,

-	src/sfnt/sferrors.h: Updated.

-

-2013-03-11  Werner Lemberg  <[email protected]>

-

-	[gxvalid] Fix module error.

-

-	* src/gxvalid/gxverror.h (FT_ERR_BASE): Define as

-	FT_Mod_Err_GXvalid.

-	* include/freetype/ftmoderr.h: Add module error for `GXvalid'.

-

-2013-03-11  Werner Lemberg  <[email protected]>

-

-	Always use module related error codes.

-

-	* src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c

-	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use

-	`FT_ERROR_BASE'.

-

-	* src/type1/t1load.c (parse_encoding): Use

-	T1_Err_Unknown_File_Format.

-

-2013-03-08  Werner Lemberg  <[email protected]>

-

-	[cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.

-

-	Problem reported by Khaled Hosny <[email protected]>.

-

-	* src/cff/cffgload.c (cff_slot_load): Implement it.

-

-2013-02-23  Alexei Podtelezhnikov  <[email protected]>

-

-	[base] Fix commit ab02d9e8.

-

-	* src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.

-

-2013-02-19  Alexei Podtelezhnikov  <[email protected]>

-

-	[base] New bisecting BBox_Cubic_Check (disabled).

-

-	* src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm

-	for extremum search built around simple condition that defines

-	which half contains the extremum.

-

-2013-02-18  Alexei Podtelezhnikov  <[email protected]>

-

-	[tools] Update BBox testing tool.

-

-	* src/tools/test_bbox.c: Add another cubic outline with exact BBox.

-	(REPEAT): Increase the number of benchmarking cycles.

-	(profile_outline): Tweak output formatting.

-

-2013-02-02  Werner Lemberg  <[email protected]>

-

-	Fix Savannah bug #38235.

-

-	* builds/unix/configure.raw: Don't generate `freetype-config' and

-	`freetype.pc'.

-

-	* builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,

-	build_libtool_libs, ft_version): New variables to be substituted.

-	(freetype-config, freetype.pc): New rules to generate those files.

-

-	* builds/unix/freetype-config.in: Remove code for handling `rpath'.

-	The use of $rpath has been accidentally removed in a patch from

-	2009-12-22, and apparently noone has missed it since.

-	Use `%' instead of `@' as a variable substitution marker.

-	Use quotes.

-

-	* builds/unix/freetype.in: Use `%' instead of `@' as a variable

-	substitution marker.

-	Use quotes.

-

-2013-02-07  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.

-

-	BTW, Greg agrees that the OpenType specification is missing the list

-	of GS variables which will always be reset to the default values

-	after the `prep' table has been executed.

-

-2013-02-06  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.

-

-	Up to now, we simply took a snapshot of the Graphics State after the

-	`prep' table has been executed, and right before a glyph's bytecode

-	was run it got reloaded.  However, as Greg Hitchcock has told us in

-	private communication, reference points get reset to zero in the MS

-	rasterizer and we follow in due course.  While reasonable, this is

-	undocumented behaviour.

-

-	Most notably, this fixes the rendering of Arial's `x' glyph in

-

-	[truetype] Improve subpixel code.

-

-	This patches fixes many issues with the ttsubpix implementation.

-

-	1. Data tables are defined, instead of declared, in the header, and

-	   thus copied into each source file that includes it.

-

-	2. These tables were defined as global, mutable, visible variables,

-	   and thus costing private RAM to every process that loads the

-	   library (> 50 KB / process, this is huge!).

-

-	   Additionally, this also made the library export the symbols

-	   completely needlessly.

-

-	3. Missing `sph_' and `SPH_' prefixes to some of the definitions.

-

-	Note that this doesn't try to fix the incredibly inefficient storage

-	format for the data tables used by the code.  This one will require

-	another pass in the future.

-

-	* src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS):

-	Renamed to...

-

-	[truetype] Improve accuracy of normalization of short vectors.

-

-	Unit vector components are stored as 2.14 fixed-point numbers. In

-	order to calculate all 14 bits accurately, a short vector to be

-	normalized has to be upscaled to at least 14 bits before its length

-	is calculated. This has been safe since accurate CORDIC algorithms

-	were adopted.

-

-	* src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000.

-

-2013-01-12  Alexei Podtelezhnikov  <[email protected]>

-

-	[truetype] Kill very old vector normalization hacks.

-

-	Back in the days, vector length calculations were not very accurate

-

-	[base] Improve trigonometric core.

-

-	FreeType used to rely on a 24-step iteration CORDIC algorithm to

-	calculate trigonometric functions and rotate vectors. It turns out

-	that once the vector is in the right half-plane, the initial rotation

-	by 63 degrees is not necessary. The algorithm is perfectly capable

-	to converge to any angle starting from the second 45 degree rotation.

-	This patch removes the first rotation and makes it a 23-step CORDIC

-	algorithm.

-	The dot product between freeVector and projVector or cosine of

-	the angle between these FT_F2Dot14 unit vectors used to be scaled up

-	by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.

-	This patch scales the value down by 2^14 instead, which simplifies

-	its use throughout the bytecode interpreter.

-

-	This does not lead to the loss of precision because the lower bits

-	are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)

-	for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.

-	These vectors are stored as (0x4000,0) and (0x2666,0x3333) after

-	rounding and F_dot_P is assigned 0x26660000. The lower bits were

-	already lost while rounding the unit vector components.

-

-	Besides code simplification, this change can lead to better

-	performance when FT_MulDiv with the scaled-down F_dot_P is less

-	likely to use the costly 64-bit path. We are not changing the type

-	of F_dot_P to FT_F2Dot14 at this point.

-

-	* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14

-	bits and modify its use accordingly.

-	(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify

-	the use of F_dot_P field.

-	* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary

-	assignment of F_dot_P to its theoretical maximum in case we decide

-	to scale back its type later.

-	`-static' works

-

-	In FreeType, no is received, unless bzip2 and zlib are disabled using

-

-	  ./configure --without-bzip2 --without-zlib

-

-	The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to

-

-	[truetype] Remove unused rounding functionality.

-

-	The subpixel hinting patch contained the concept of an adjustable

-	number of gridlines per pixel.  This is no longer used due to x

-	being completely ignored instead.  This will return some of the

-	code to its existing state prior to the original Infinality

-	commit.

-

-	[truetype] Support subpixel hinting.

-

-	This is the large, famous `Infinality' patch to support ClearType

-	bytecode which has been available from

-	http://www.infinality.net/blog/ for some time, and which has been

-	refined over the last years.  While still experimental, it is now

-	mature enough to be included directly into FreeType.

-

-	Most of the code is based on the ClearType whitepaper written by

-	Greg Hitchcock

-

-	  https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

-

-	which gives a detailed overview of the necessary changes to the

-	Microsoft rasterizer so that older fonts are supported.  However, a

-	lot of details are still missing, and this patches provides a

-	framework to easily handle rendering issues down to the glyph level

-	of certain fonts.

-

-	Note that ClearType support is not completely implemented!  In

-	particular, full support for the options `compatible_widths',

-	`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode

-	instruction) is missing.

-

-	* src/truetype/ttsubpix.c: New file, providing code to handle

-	`tweaks', this is, rules for certain glyphs in certain fonts

-	(including wildcards) which need a special treatment.

-

-	* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

-

-	* include/freetype/config/ftoption.h, src/devel/ftoption.h

-	(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

-

-	* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,

-	FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

-

-	* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include

-	`ttsubpix.c'.

-

-	* src/truetype/ttgload.c: Include `ttsubpix.h'.

-	[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

-

-	(tt_get_metrics): Set tweak flags.

-	(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.

-	(TT_Process_Simple_Glyph): Compensate emboldening if necessary.

-	(compute_glyph_metrics): Handle `compatible widths' option.

-	(tt_loader_init): Handle ClearType GETINFO information bits.

-

-	* src/truetype/rules.mk (TT_DRV_SRC): Updated.

-

-	* src/truetype/ttinterp.c: Include `ttsubpix.h'.

-	pixel.

-	(SET_SuperRound, ROUND_None, CUR_Func_round): Updated.

-	(DO_SROUND, DOS45ROUND, DO_ODD, DO_EVEN): Updated.

-	(DO_ROUND, DO_NROUND): Updated.

-	(DO_RS): Take care of `Typeman' bytecode patterns.

-	`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;

-	the first component, `E', has an advance width of 1366 font units,

-	while the advance width of the composite itself (which looks like

-	uppercase `E' with dieresis) is 1367 font units.  I think this is

-	actually a bug in the font itself, because there is no reason that

-	this glyph has not the same width as uppercase `E' without the

-	dieresis.  Anyway, it helped identify this problem.

-

-	Using the TrueType hinter, the correct value (1367) of `afii10023'

-	was returned, but the autohinter mysteriously returned 1366.

-

-	Digging in the code showed that the autohinter recursively calls

-	FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load

-	flag.  However, the `linearHoriAdvance' field is still returned as a

-	scaled value.  To avoid scaling twice, the old code in autofit reset

-	`linearHoriAdvance', using the `horiAdvance' field.  This seemed to

-	work since FT_LOAD_NO_SCALE was in use, but it failed actually,

-	because `horiAdvance' is defined as the distance of the first

-	subglyph's phantom points, which in turn are initialized using the

-	advance width of the first subglyph.  And as the given example

-	shows, these widths can differ.

-

-	* src/autofit/afloader.c (af_loader_load_g): Temporarily set

-	FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled

-	values for the linear advance widths.

-	[truetype] Fix SSW instruction.

-

-	Fix redundant declaration warning in PIC mode.

-

-	Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were

-	designed to declare xxx_pic_{free,init} by themselves.

-	Because these macros are used at the end of the module

-	interface (e.g. ttdriver.c) and the wrapper source to build

-	a module as a single object (e.g. truetype.c) includes

-	the PIC file (e.g. ttpic.c) before the module interface,

-	these macros are expanded AFTER xxx_pic_{free,init} body

-	when the modules are built as single object.

-	The declaration after the implementation causes the redundant

-	declaration warnings, so the declarations are moved to module

-	PIC headers (e.g. ttpic.h).  Separating to other header files

-	are needed for multi build.

-

-	* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):

-	Remove class_##_pic_free and class_##_pic_init declarations.

-	* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,

-	FT_DEFINE_MODULE): Ditto.

-

-

-	* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC

-	configuration, FT_DEFAULT_MODULES_GET returns

-	FT_Module_Class** pointer, GCC 4.6 warns that

-	const FT_Module_Class* const* variable is warned as

-	inappropriate to store it.  To calm it, explicit cast is

-	inserted.  Also `library' is checked to prevent the NULL

-	pointer dereference in FT_DEFAULT_MODULES_GET.

-

-	[mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.

-

-	Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON

-	was a configurable macro to disable Carbon-dependent code.  Because

-	now configure script sets DARWIN_NO_CARBON by default and disables

-	Darwin & Carbon-dependent codes, these macros can be unified.

-	FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON

-	(defined by default) is removed, because DARWIN_NO_CARBON violates

-	FT_XXX naming convention of public macros, and a macro configured by

-	default is not portable for the building without configure (e.g.

-	make devel).

-

-	* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based

-	old Mac font support is requested and Carbon is available.

-	* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support

-	for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is

-	requested.

-	[bdf] Fix Savannah bug #34896.

-

-	ENCODING now covers the whole Unicode range.

-

-	Note, however, that this change is quite expensive since it

-	increases the size of three arrays by almost 400kByte in total.  The

-	right fix is to replace the logic with something smarter.

-	Additionally, there exist very old BDFs for three-byte CCCII

-	encoding which exceeds the range of Unicode (another reason to have

-	a smarter logic).

-

-	* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'

-

-2011-09-11  Tomas Hoger  <[email protected]>

-

-	Slightly improve LZW_CLEAR handling.

-

-	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:

-	Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are

-	handled as clear codes.  This also re-sets old_code and old_char to

-	predictable values, which is a little better than using `random'

-	ones if the code following LZW_CLEAR is invalid.

-

-2011-09-11  Tomas Hoger  <[email protected]>

-

-	Add explicit LZW decompression stack size limit.

-

-	Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is

-	constructed correctly.  It's even less than that, see e.g.

-	libarchive code comment for a better size upper bound:

-

-	  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121

-

-	This patch adds explicit stack size limit, enforced when stack is

-	realloced.

-

-	An alternative is to ensure that code < state->prefix[code - 256]

-	when traversing prefix table.  Such check is less efficient and

-	should not be required if prefix table is constructed correctly in

-	the first place.

-

-	* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.

-

-2011-09-11  Tomas Hoger  <[email protected]>

-

-	Protect against loops in the prefix table.

-

-	LZW decompressor did not sufficiently check codes read from the

-	input LZW stream.  A specially-crafted or corrupted input could

-	create a loop in the prefix table, which leads to memory usage

-	spikes, as there's no decompression stack size limit.

-

-	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First

-	code in valid LZW stream must be 0..255.

-	<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,

-	code > free_ent is invalid.

-

-

-	[ftstroke] Major revision.

-

-	The main problems

-	-----------------

-

-	  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter

-	    joins (not bevel joins) were generated.  Indeed, the meanings of

-	    `miter' and `bevel' were incorrectly reversed (consistently) in

-	    both the code and comments.

-

-	  o The way bevel joins were constructed (whether specified

-	    explicitly, or created as a result of exceeding the miter limit)

-	    did not match what is required for stroked text in PostScript or

-	    PDF.

-

-	The main fixes

-	--------------

-

-	  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

-

-	  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been

-	    introduced to support PostScript and PDF miter joins.

-

-	  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an

-	    alias for FT_STROKER_LINEJOIN_MITER.

-

-	Additionally, a variety of stroking errors have been fixed.  These

-	would cause various artifacts (including points `at infinity'),

-	especially when stroking poor quality fonts.

-

-	See

-

-	  https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html

-

-	for example documents.  The FreeType stroker now produces results

-	very similar to that produced by GhostScript and Distiller for these

-	fonts.

-

-	Other problems

-	--------------

-

-	The following problems have been resolved:

-

-	  o Inside corners could be generated incorrectly.  Intersecting the

-	    inside corner could cause a missing triangular area and other

-	    effects.

-

-	    The intersection point can only be used if the join is between

-	    two lines and both lines are long enough.  The `optimization'

-	    condition in `ft_stroker_inside' has been corrected; this

-	    requires the line length to be passed into various functions and

-	    stored in `FT_StrokerRec'.

-

-	  o Incorrect cubic curves could be generated.  The angle

-	    calculations in `FT_Stroker_CubicTo' have been corrected to

-	    handle the case of the curve crossing the +/-PI direction.

-

-	  o If the border radius was greater than the radius of curvature of

-	    a curve, then the negative sector would end up outside (not

-	    inside) the border.  This situation is now recognized and the

-	    negative sector is circumnavigated in the opposite direction.

-	    (If round line joins are being used, this code is disabled

-	    because the line join will always cover the negative sector.)

-

-	  o When a curve is split, the arcs may not join smoothly (especially

-	    if the curve turns sharply back on itself).  Changes in

-	    direction between adjacent arcs were not handled.  A round

-	    corner is now added if the deviation from one arc to the next is

-	    greater than a suitable threshold.

-

-	  o The current direction wasn't retained if a the outline contained

-	    a zero length lineto or a curve that was determined to be

-	    `basically a point'.  This could cause a spurious join to be

-	    added.

-

-	  o Cubics with close control points could be mishandled.  All eight

-	    cases are now distinguished correctly.

-

-	Other improvements

-	------------------

-

-	o Borders for cubic curves could be too `flat'.

-	  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent

-	  this.

-

-	o The handling and use of movable points has been simplified a

-	  little.

-

-	o Various values are now computed only if the results are actually

-	  needed.

-

-	o The directions of the outer and inner borders have been swapped,

-	  as recommended by Graham Asher.

-	[raster] Add undocumented drop-out rule to the other bbox side also.

-

-	* src/raster/ftraster.c (Vertical_Sweep_Drop,

-

-2011-01-13  Werner Lemberg  <[email protected]>

-

-	[raster] Reduce jitter value.

-

-	This catches a rendering problem with glyph `x' from Tahoma at

-	10ppem.  It seems that the increase of the precision in the change

-	from 2009-06-11 makes a larger jitter value unnecessary.

-

-	* src/raster/ftraster.c (Set_High_Precision): Implement it.

-

-2011-01-13  Werner Lemberg  <[email protected]>

-

-	[raster] Handle drop-outs at glyph borders according to Microsoft.

-

-	If a drop-out rule would switch on a pixel outside of the glyph's

-	bounding box, use the right (or top) pixel instead.  This is an

-	undocumented feature, but some fonts like `Helvetica Neue LT Com 65

-	Medium' heavily rely on it.

-

-	Thanks to Greg Hitchcock who explained this behaviour.

-

-	[cache] Fix Savannah bug #31923, patch drafted by Harsha.

-

-	When a node comparator changes the cached nodes during the

-	search of a node matching with queried properties, the

-	pointers obtained before the function should be updated to

-	prevent the dereference to freed or reallocated nodes.

-	To minimize the rescan of the linked list, the update is

-	executed when the comparator notifies the change of cached

-	nodes. This change depends previous change:

-	38b272ffbbdaae276d636aec4ef84af407d16181

-

-	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the

-	top node if the cached nodes are changed.

-	* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.

-

-2011-01-09  suzuki toshiya  <[email protected]>

-

-	[cache] Notice if a cache query induced the node list change.

-

-	Some node comparators (comparing the cache node contents and the

-	properties specified by the query) can flush the cache node to

-	prevent the cache inflation.  The change may invalidate the pointers

-	to the node obtained before the node comparison, so it should be

-	noticed to the caller.  The problem caused by the cache node

-	changing is reported by Harsha, see Savannah bug #31923.

-

-	* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument

-	`FT_Bool* list_changed' to indicate the change of the cached nodes

-	to the caller.

-	(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by

-	`_list_changed'.

-	(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'

-	and update it when `FTC_Manager_FlushN' flushes any nodes.

-

-	* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new

-	FTC_Node_CompareFunc type.

-	(ftc_gnode_compare): Ditto.

-

-	* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use

-	TRUE/FALSE macros.

-	(ftc_basic_gnode_compare_faceid): New argument `FT_Bool*

-	list_changed' to indicate the change of the cache nodes (anyway, it

-	is always FALSE).

-

-	* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use

-	TRUE/FALSE macros.

-	(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to

-	indicate the change of the cache nodes (anyway, it is always FALSE).

-	(ftc_cmap_node_remove_faceid): Ditto.

-

-	* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to

-	`FTC_CACHE_TRYLOOP_END', because the result is not needed.

-	(FTC_Cache_Lookup): Watch the change of the cache nodes by

-	`list_changed'.

-	(FTC_Cache_RemoveFaceID): Ditto.

-

-	* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use

-	TRUE/FALSE macros.

-	(ftc_gnode_compare): New argument `FT_Bool* list_changed' to

-	passed to `ftc_gnode_compare'.

-	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.

-

-	* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*

-	list_changed' to indicate the change of the cache nodes, anyway.  It

-	is updated by `FTC_CACHE_TRYLOOP'.

-	(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be

-	passed to `ftc_snode_compare'.

-	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

-

-2011-01-09  suzuki toshiya  <[email protected]>

-

-	[cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.

-

-	* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd

-	argument `FTC_Cache  cache' to fit FTC_Node_CompareFunc

-	prototype.

-	* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,

-	`cache' is not used by its child `ftc_gnode_compare'.

-

-2011-01-09  suzuki toshiya  <[email protected]>

-

-	[cache] Deduplicate the code to get the top node by a hash.

-

-	There are several duplicated code fragments getting the top node

-	from a cache by a given hash, like:

-

-	    idx = hash & cache->mask;

-	    if ( idx < cache->p )

-	      idx = hash & ( cache->mask * 2 + 1 );

-	    pnode = cache->buckets + idx;

-

-	To remove duplication, a cpp-macro to do same work

-	`FTC_NODE__TOP_FOR_HASH' is introduced.  For non-inlined

-	configuration, non-`ftc_get_top_node_for_hash' is also introduced.

-

-	* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare

-	and implement inlined version.

-	(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.

-	* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined

-	version.

-	(ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.

-	(ftc_node_hash_link): Ditto.

-	(FTC_Cache_Lookup): Ditto.

-

-2011-01-09  suzuki toshiya  <[email protected]>

-

-	[cache] inline-specific functions are conditionalized.

-

-	* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for

-	inlined configuration.  This function is a thin wrapper of

-	`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see

-	`nodecmp' argument).  Under non-inlined configuration,

-	`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via

-	`FTC_Cache->clazz.node_compare'.

-

-	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.

-	* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for

-	`ftc_snode_compare'.

-	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

-

-2011-01-09  suzuki toshiya  <[email protected]>

-

-	[cache] Correct a type mismatch under non-inlined config.

-

-	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'

-	takes the node via a pointer `FTC_Node*', differently from cpp-macro

-	`FTC_CACHE_LOOKUP_CMP'.

-2011-01-05  suzuki toshiya  <[email protected]>

-

-	* builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.

-

-	SYSTEM_ZLIB is used to switch the builtin zlib source

-2010-12-25  Harsha  <[email protected]>

-

-	Apply Savannah patch #7422.

-

-	If we encounter a space in a string then the sbit buffer is NULL,

-	height and width are 0s.  So the check in ftc_snode_compare will

-	always pass for spaces (comparison with 255).  Here the comments

-	above the condition are proper but the implementation is not.  When

-	we create an snode I think it is the proper way to initialize the

-	width to 255 and then put a check for being equal to 255 in snode

-	compare function.

-

-	* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with

-	value 255.

-	(ftc_snode_compare): Fix condition.

-

-2010-10-24  suzuki toshiya  <[email protected]>

-

-	[cache] Change the hash types to FT_PtrDist.

-

-	On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)

-	variables are inappropriate to calculate hash values

-	from the memory address (64-bit).  The hash variables

-	are extended from FT_ULong to FT_PtrDist and new

-	hashing macro functions are introduced.  The hash

-	values on 16-bit memory platforms are changed, but

-	ILP32 and LP64 are not changed.  The hash value in

-	the cache subsystem is not reverted to the memory

-	address, so using signed type FT_PtrDist is safe.

-

-	* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash

-	function to replace `FTC_FACE_ID_HASH' for portability.

-	* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace

-	`FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.

-	* src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.

-

-	* src/cache/ftccache.h (FTC_NodeRec): The type of the

-	member `hash' is changed from FT_UInt32 to FT_PtrDist.

-

-	* src/cache/ftccache.h (FTC_Cache_Lookup): The type of the

-	argument `hash' is changed from FT_UInt32 to FT_PtrDist.

-	* src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.

-

-	* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type

-	of the internal variable `hash' is changed to FT_PtrDist

-	from FT_UInt32.  (FTC_ImageCache_LookupScaler): Ditto.

-	(FTC_SBitCache_Lookup): Ditto.

-	(FTC_SBitCache_LookupScaler): Ditto.

-	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.

-	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.

-	Also the type of the internal variable `_idx' is changed to

-	FT_PtrDist from FT_UFast for better pointer calculation.

-	[cache] Hide internal macros incompatible with LLP64.

-

-	`FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and

-

-	Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.

-

-	On LLP64 platforms (e.g. Win64), unsigned long (32-bit)

-	cannot cover the memory address (64-bit).  `FT_MEM_VAL' is

-	used for hashing only and not dereferred, so using signed

-	type FT_PtrDist is safe.

-

-	* src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the

-	return value from FT_ULong to FT_PtrDist.

-	(ft_mem_table_resize): The type of hash is changed to

-	FT_PtrDist.  (ft_mem_table_get_nodep): Ditto.

-

-	Replace "%lx" for memory address by "%p", LLP64 platforms.

-

-	On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover

-	the memory address (64-bit).  Also the casts from the pointer

-	type to long int should be removed to preserve the address

-	correctly.

-

-	* src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".

-	(End_Profile) Ditto.

-	* src/truetype/ttinterp.c (Init_Context): Ditto.

-	* src/base/ftobjs.c (load_face_in_embedded_rfork):

-	When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it

-	means that the file is possible to be `fopen'-ed but zero-sized.

-	Also there is a case that the resource fork is not zero-sized,

-	but no supported font exists in it.  If a rule by Darwin VFS

-	falls into such cases, there is no need to try other Darwin VFS

-	rules anymore.  Such cases are marked by vfs_rfork_has_no_font.

-	If it is TRUE, the Darwin VFS rules are skipped.

-

-	[raccess] Grouping resource access rules based on Darwin VFS.

-

-	MacOS X/Darwin kernel supports a few tricky methods to access

-	a resource fork via ANSI C or POSIX interface.  Current resource

-	fork accessor tries all possible methods to support all kernels.

-	But if a method could open a resource fork but no font is found,

-	there is no need to try other methods older than tested method.

-	To determine whether the rule index is for Darwin VFS, a local

-	function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.

-	To use this function in ftobjs.c etc but it should be inlined,

-	it is exposed by ftbase.h.

-

-	* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify

-	the rules to access the resource fork.

-	(raccess_guess_rec): New structure to bind the rule function and

-	rule enum type.

-	(FT_Raccess_Guess): The list of the rule functions is replaced by

-	(raccess_guess_table): This.  This is exposed to be used by other

-	intra module functions.

-	(raccess_rule_by_darwin_vfs): A function to return a boolean

-	if the rule specified by the rule index is based on Darwin VFS.

-

-	Prevent to open a FT_Stream for zero-sized file on non-Unix.

-

-	builds/unix/ftsystem.c prevents to open an useless stream from

-	zero-sized file and returns FT_Err_Cannot_Open_Stream, but the

-	stream drivers for ANSI C, Amiga and VMS return useless streams.

-	For cross-platform consistency, all stream drivers should act

-	same.

-

-	* src/base/ftsystem.c (FT_Stream_Open): If the size of the opened

-	file is zero, FT_Err_Cannot_Open_Stream is returned.

-	* builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.

-	* src/vms/ftsystem.c (FT_Stream_Open): Ditto.

-

-	[cff] Truncate the element length at the end of the stream.

-	See Savannah bug #30975.

-

-	* src/cff/cffload.c (cff_index_access_element): `off2', the offset

-	to the next element is truncated at the end of the stream to prevent

-	invalid I/O.  As `off1', the offset to the requested element has

-	been checked by `FT_STREAM_SEEK', `off2' should be checked

-	similarly.

-

-	See Savannah bug #30975.

-

-	* src/truetype/ttpload.c (tt_face_get_location): If `pos1', the

-	offset to the requested entry in `glyf' exceeds the end of the

-

-	[truetype] Don't duplicate size->twilight structure to be freed.

-	See Savannah bug #31040 for detail.

-

-	* src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate

-	FT_GlyphZoneRec size->twilight to be freed.  If duplicated,

-	`FT_FREE' erases the duplicated pointers only and leave original

-	pointers.  They can cause the double-free crash when the burst

-	errors occur in TrueType interpreter and `free_buffer_in_size' is

-	invoked repeatedly.

-

-2010-09-15  Werner Lemberg  <[email protected]>

-

-	Make bytecode debugging with FontForge work again.

-

-	Patch is suggested by Adrian Bunk, to prevent unexpected

-	reflection of environmental LIBTOOL.  See:

-	https://savannah.nongnu.org/patch/?7290

-

-	* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to

-	$(FT_LIBTOOL_DIR)/libtool.  FT_LIBTOOL_DIR is set to $(BUILD_DIR)

-	by default.

-	* configure: When configured for the building out of source tee,

-	FT_LIBTOOL_DIR is set to $(OBJ_DIR).

-

-	[truetype] Decrease the trace level catching the interpreter error.

-

-	* src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level

-

-2010-08-30  suzuki toshiya  <[email protected]>

-

-	[truetype] Prevent bytecode reuse after the interpretation error.

-

-	* src/truetype/ttinterp.c (free_buffer_in_size): New function to

-	free the buffer allocated during the interpretation of this glyph.

-	(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if

-	an error occurs in the bytecode interpretation.  The interpretation

-	of invalid bytecode may break the function definitions and referring

-	them in later interpretation is danger.  By unsetting these flags,

-	`fpgm' and `prep' tables are executed again in next interpretation.

-

-	Force hinting when the font lacks its familyname.

-

-	In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt

-

-	[psaux] Fix Savannah bug #29846.

-

-	Previously we discovered fonts which used `setcurrentpoint' to set

-	the initial point of a contour to 0,0.  This caused FreeType to

-	raise an error, because the `setcurrentpoint' operator is only

-	supposed to be used with the results from an OtherSubr subroutine.

-

-	This was fixed by simply ignoring the error and carrying on.

-

-	Now we have found a font which uses setcurrentpoint to actually

-	establish a non-zero point for a contour during the course of a

-	glyph program.  FWIW, these files may be produced by an application

-	called `Intaglio' on the Mac, when converting TrueType fonts to

-	Type 1.

-

-	The fix allows the new invalid behaviour, the old invalid behaviour

-	and real proper usage of the operator to work the same way as Adobe

-	interpreters apparently do.

-

-	* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make

-	`setcurrentpoint' use the top two elements of the stack to establish

-	unconditionally the current x and y coordinates.

-

-	Make the `flex' subroutine handling (OtherSubr 0) put the current

-	x,y coordinates onto the stack, instead of two dummy uninitialised

-	values.

-	[gxvalid] Fix a naming convention conflicting with ftvalid.

-

-	See previous changeset for otvalid.

-

-	* src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace

-	`valid' by `gxvalid'.

-	gxvprop.c, gxvtrak.c}: Replace `valid' by `gxvalid' if

-	it is typed as GXV_Validator.

-

-2014-12-09  suzuki toshiya  <[email protected]>

-

-	[otvalid] Fix a naming convention conflicting with ftvalid.

-

-	Some prototypes in ftvalid.h use `valid' for the variables

-	typed as FT_Validator.  Their implementations in src/base/

-	ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.

-

-	Some macros in otvcommn.h assume the exist of the variable

-	`valid' typed as OTV_Validator in the caller.

-

-	Mixing these two conventions cause invalid pointer conversion

-	and unexpected SEGV in longjmp.  To prevent it, all variables

-	typed as OTV_Validator are renamed to `otvalid'.

-

-	* src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.

-	* src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,

-	otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'

-	if it is typed as OTV_Validator.

-

-	[pcf] Fix Savannah bug #43774.

-

-	Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'

-	functions.  Since the PCF format doesn't have an official

-	specification, we have to exactly follow these functions' behaviour.

-

-	The problem was unveiled with a patch from 2014-11-06, fixing issue

-	#43547.

-

-	* src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last

-	element.  Instead, assign real size.

-2014-12-04  Dave Arnold  <[email protected]>

-

-	[cff] Modify an FT_ASSERT.

-

-	* src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah

-	bug #43661, the test font `...aspartam.otf' still triggers an

-	FT_ASSERT.  Since hintmap still works with count==0, ...

-	(cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to

-	suppress the assert.

-

-2014-12-04  Dave Arnold  <[email protected]>

-2014-12-03  Werner Lemberg  <[email protected]>

-

-	[autofit] Better fix for conversion specifiers in debug messages.

-

-	Using `%ld' for pointer differences causes warnings on 32bit

-	platforms.  The correct type would be (the relatively new) `%td',

-	however, this is missing on some important platforms.

-

-	This patch improves the change from 2014-11-28.

-

-	* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast.  Our

-	pointer differences are always sufficiently small.

-	(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,

-	af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

-

-	(get_sfnt_table): Updated.

-

-

-	. Add and update many `<Order>' tags.

-	. Apply various documentation fixes.

-	. Remove details to deprecated (or never implemented) data.

-

-2014-12-02  Werner Lemberg  <[email protected]>

-

-	[docmaker] Always handle `<Order>' section elements.

-

-	Previously, those elements were handled only for sections present in

-	a `<Sections>' chapter element.

-

-	* src/tools/docmaker/content.py (ContentProcessor::finish):

-	Implement it.

-

-2014-12-02  Werner Lemberg  <[email protected]>

-	Insert string `/empty/' between items.

-

-	* src/tools/docmaker/formatter.py (Formatter::section_dump): Make it

-	robust against nonexistent keys.

-

-	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit

-	empty <td> elements for `/empty/'.

-

-2014-12-02  Werner Lemberg  <[email protected]>

-

-	[docmaker] Ensure Python 3 compatibility.

-

-	* src/tools/docmaker/content.py (ContentProcessor::set_section,

-	ContentProcessor::finish): Replace `has_key' function with `in'

-	keyword.

-

-	* src/tools/docmaker/formatter.py (Formatter::__init__): Replace

-	sorting function with a key generator.

-	(Formatter::add_identifier): Replace `has_key' function with `in'

-2014-11-29  Werner Lemberg  <[email protected]>

-

-	[docmaker] Allow empty lines in `<Order>' blocks.

-

-	Before this patch, the suggested order of entries stopped at the

-	first empty line.

-

-	Obviously, nobody noticed that this problem caused a much reduced

-	set of links in the `Synopsis' sections; in particular, the

-	`<Order>' blocks contain a lot of entries that wouldn't be listed

-	otherwise...

-

-	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

-	New function to iterate over all items.

-	proper CSS.

-

-	Globally reduce page width to 75%.

-

-	(block_header): Rename <div> class to `section'.

-

-2014-11-29  Werner Lemberg  <[email protected]>

-	[docmaker] Add `top' links after blocks.

-

-	For `Index' and `TOC' links, we now simply use the `text-align' CSS

-	property of `<td>' to enforce flush-left and flush-right,

-2014-11-25  Werner Lemberg  <[email protected]>

-

-	[Savannah bug #43682] Add/remove `void' casts to some functions.

-

-	We use a cast to indicate that we intentionally ignore a function's

-

-	[cff, pfr, psaux, winfonts] Fix Savannah bug #43676.

-

-	Don't cast cmap init function pointers to an incompatible type.

-

-	Without this patch, the number of parameters between declaration and

-	the real signature differs.  Calling such a function results in

-	undefined behavior.

-

-	  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)

-	    6.5.2.2 Function calls

-	      9 If the function is defined with a type that is not

-	        compatible with the type (of the expression) pointed to by

-	        the expression that denotes the called function, the

-	        behavior is undefined.

-

-	On certain platforms (c -> js with emscripten) this causes

-	termination of execution or invalid calls because in the emscripten

-	implementation, function pointers of different types are stored in

-	different pointer arrays.  Incorrect pointer type here results in

-	indexing of an incorrect array.

-

-	* src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init),

-	src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c

-

-	[type42] Fix Savannah bug #43659.

-

-

-	* src/type42/t42parse.c (t42_parse_sfnts): Always set

-2014-11-19  Behdad Esfahbod  <[email protected]>

-

-	Avoid compiler warnings on x86-64 for `FT_MulFix'.

-

-	`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',

-	but several inline implementations of it in `ftcalc.h' take

-	`FT_Int32' arguments.  This is causing compiler warnings on x86-64:

-	If parameters of type `FT_Fixed' (= `FT_Long') are passed to the

-	inline implementation of this function, integer values are truncated

-	from 64bit to 32bit.

-

-

-	[base] CORDIC improvements.

-

-	The scaling between the hypotenuse and its CORDIC approximation is

-

-2014-11-03  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.

-

-	Before this patch, it was impossible to ever call DELTAP[123] in

-	subpixel hinting mode as described in the ClearType whitepaper; it

-	only worked if in `compatibility mode'.  However, compatibility mode

-	essentially disables SHPIX, completely ruining hinting of

-	ttfautohint output, for example.

-

-	We now follow the whitepaper more closely so that DELTAP[123]

-	instructions for touched points in the non-subpixel direction are

-	executed.

-

-	[autofit] Fix Savannah bug #42148.

-

-	The adaptation of the cjk auto-hinter module to blue stringsets in

-	2013-08-25 had three severe bugs.  Mea culpa.

-

-	1. Contrary to the latin auto-hinter, characters for reference and

-	   overshoot values of a blue zone are specified separately.  Due to

-	   the screwed-up change it didn't work at all.

-

-	2. A boolean comparison was erroneously replaced with a cast,

-	   causing invalid results with the `^' operator later on.  The

-	   visual artifact caused by this problem is the topic of the bug

-	   report.

-

-	3. Two flag values were inverted, causing incorrect assignment of

-	   reference and overshoot values.

-

-	* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new

-	syntax to have both reference and overshoot characters in a single

-	string.  This is error #1.

-	Add extensive comments.

-

-	* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no

-	longer used.

-	(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.

-	This is error #3.

-

-	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

-

-	* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.

-	Use character `|' to separate characters for reference and overshoot

-	values.

-	Improve tracing messages, synchronizing them with the latin

-	auto-hinter.

-	(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.

-	This is error #2.

-	(af_cjk_align_linked_edge): Add tracing message.

-

-	* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer

-	used.

-

-2014-04-17  Werner Lemberg  <[email protected]>

-

-	[autofit] More coverage fixes for complex scripts.

-

-	* src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage

-	of GSUB lookups into output coverage.  Otherwise, ligatures are not

-	handled properly.

-	Don't check blue zone characters for default coverage.

-

-2014-04-17  Werner Lemberg  <[email protected]>

-

-	Make `FT_Get_SubGlyph_Info' actually work.

-

-	* src/base/ftobjs.c (FT_Get_SubGlyph_Info): Return FT_Err_Ok

-

-	[autofit] Improve coverage handling.

-

-	* src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs

-	appearing in the GPOS table if we are processing the default

-	coverage.

-

-

-	[smooth] Fix stand-alone compilation.

-

-	* src/smooth/ftgrays.c (FT_BEGIN_STMNT, FT_END_STMNT): Define.

-

-2014-04-12  Werner Lemberg  <[email protected]>

-

-	[autofit] Redesign the recognition algorithm of strong points.

-

-	In particular, local extrema without horizontal or vertical segments

-	are better recognized:

-

-	  + A                + D

-	   \                /

-	    \              /

-	     \            /

-	      \          /

-	       \        + C

-	        \    /

-	       B +/

-

-	If the distances AB and CD are large, point B wasn't previously

-	detected as an extremum since the `ft_corner_is_flat' function

-	`swallowed' BC regardless of its direction, tagging point B as weak.

-	The next iteration started at B and made `ft_corner_is_flat' swallow

-	point C, tagging it as weak also, et voilà.

-

-	To improve that, another pass gets now performed before calling

-	`ft_corner_is_flat' to improve the `topology' of an outline: A

-	sequence of non-horizontal or non-vertical vectors that point into

-	the same quadrant are handled as a single, large vector.

-

-	Additionally, distances of near points are now accumulated, which

-	makes the auto-hinter handle them as if they were prepended to the

-	next non-near vector.

-

-	This generally improves the auto-hinter's rendering results.

-

-	* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.

-

-	* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag

-	`AF_FLAG_NEAR'.

-

-2014-04-05  Werner Lemberg  <[email protected]>

-

-	[autofit] Improve scoring algorithm for identifying stems.

-

-	Problem reported by Karsten Lücke <[email protected]>.

-

-	The new algorithm takes care of the width of stems: If the distance

-	between two segments is larger than the largest stem width, the

-	demerits quickly increase for larger distances.  This improves

-	hinting of slanted fonts (especially if the inner parts of serifs

-	have non-horizontal `shoulders'), avoiding false stem links.

-

-	* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest

-	stem width (if available) to compute better demerits for distances

-	between stems.

-	(af_latin_hints_detect_features): Pass stem width array and array

-	size.

-	(af_latin_metrics_init_widths): Updated to use original algorithm.

-	(af_latin_hints_apply): Updated to use new algorithm.

-

-	Work around a bug in pkg-config version 0.28 and earlier: If a

-

-	[bdf] Fix Savannah bug #41692.

-

-	bdflib puts data from the input stream into a buffer in chunks of

-	1024 bytes.  The data itself gets then parsed line by line, simply

-	increasing the current pointer into the buffer; if the search for

-	the final newline character exceeds the buffer size, more data gets

-	read.

-

-	However, in case the current line's end is very near to the buffer

-	end, and the keyword to compare with is longer than the current

-	line's length, an out-of-bounds read might happen since `memcmp'

-	doesn't stop properly at the string end.

-

-	* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons

-	stop at string ends.

-	[autofit] Fix Indic scripts.

-

-	Split the single, incorrect Indic entry into separate scripts so

-	that the covered ranges are the same: Bengali, Devanagari, Gujarati,

-	Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,

-	Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove

-	entries for Meetei Mayek and Sharada – the Unicode ranges were

-	incorrect (and nobody has complained about that), fonts are scarce

-	for those scripts, and the Indic auto-hinter support is rudimentary

-	anyways.

-

-	* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and

-

-	[autofit] Don't combine multiple features into one set.

-	Combining them, as originally envisioned, would lead to much more

-	[ftrfork] Fix the face order difference between POSIX and Carbon.

-

-	The fragmented resources in Suitcase and .dfont should be reordered

-	when `POST' resource for Type1 is being restored, but reordering of

-	sfnt resources induces the different face order.  Now the ordering

-	is restricted to `POST' resource only, to prevent the different

-

-	[autofit] Introduce `coverages'.

-

-	Coverages are the interface to the HarfBuzz library to access

-

-	Right now, compilation of HarfBuzz is only added to the development

-	build.  A solution for standard build mode will be delayed until

-	HarfBuzz gets split into two libraries to avoid mutual dependencies

-	between FreeType and HarfBuzz.

-

-	providing the framework only.  Code for handling selected OpenType

-	features (this is, actually using the data in `afcover.h') will

-	phantom point.  This is wrong, since the horizontal phantom points

-	get rounded horizontally later on.

-

-2013-11-13  Werner Lemberg  <[email protected]>

-

-	Simplify header file hierarchy.

-

-	This large patch changes the header file directory layout from

-	`include/freetype/...' to `include/...', effectively removing one

-	level.  Since the file `ft2build.h' is also located in `include'

-	(and it stays there even after installation), all FreeType header

-	files are now in a single directory.

-

-	Applications that use (a) `freetype-config' or FreeType's

-	`pkg-config' file to get the include directory for the compiler, and

-	(b) the documented way for header inclusion like

-

-	  #include <ft2build.h>

-	  #include FT_FREETYPE_H

-	  ...

-

-	don't need any change to the source code.

-

-	* include/freetype/*: Move up to...

-	* include/*: ... this directory.

-

-	* builds/amiga/include/freetype/*: Move up to...

-	* builds/amiga/include/*: ... this directory.

-

-	*/*: Essentially do `s@/freetype/@/@' where appropriate.

-

-	* CMakeLists.txt: Simplify.

-	* builds/unix/freetype-config.in, builds/unix/freetype2.in: For

-	`--cflags', return a single directory.

-	* builds/unix/install.mk (install): No longer try to remove `cache'

-	and `internal' subdirectories; instead, remove the `freetype'

-	subdirectory.

-2013-11-01  Werner Lemberg  <[email protected]>

-

-	[truetype] Minor code refactoring.

-

-	Two benefits: The allocated FDEF (and IDEF) array gets slightly

-	smaller, and the `ttdebug' demo program has access to function

-	numbers without additional costs.

-

-	Fortunately, no changes to FontForge are necessary – this is the

-	only external TrueType debugger I know of, but others may exist and

-	should check the code accordingly.

-

-	* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and

-	`Cur_End' with a pointer to the corresponding `TT_DefRecord'

-	structure.

-

-	[arm] Fix thumb2 inline assembly under LLVM.

-

-	When using `ADD' with an immediate operand, the instruction is

-	actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the

-	immediate operand cannot exceed 4095.  It will fail to compile with

-	LLVM.

-

-	However, in GCC, due to some legacy compatibility considerations,

-	`ADD.W' will be automatically emitted when the immediate operand is

-

-	* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.

-

-	Note that the old code avoided using a region of the piecewise

-	different section of the function, which produced a different,

-	incorrect amount of darkening.

-

-	* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.

-

-	This line was lost in commit 89ca1fd6 (from 2013-06-25).  The effect

-	is to use a previous darkening amount when producing an unhinted,

-	unscaled outline.  This can cause autohint samples in ftgrid and

-	ftview to be based on darkened CFF outlines instead of unhinted,

-	undarkened ones.

-

-2013-09-29  Dave Arnold  <[email protected]>

-

-	Fix Savannah bug #39295.

-

-	The bug was caused by switching to the initial hintmap (the one in

-	effect when `moveto' executes) just before drawing the final element

-	in the charstring.  This ensured that the path was closed (in both

-	Character Space and Device Space).  But if the final element was a

-	curve and if the final hintmap was different enough from the initial

-	one, then the curve was visibly distorted.

-

-	The first part of the fix is to draw the final curve using the final

-	hintmap as specified by the charstring.  This corrects the

-	distortion but does not ensure closing in Device Space.  It may

-	require the rasterizer to automatically generate an extra closing

-	line.  Depending on the hintmap differences, this line could be from

-	zero to a couple pixels in length.

-

-	The second part of the fix covers the case where the charstring

-	subpath is closed with an explicit line.  We now modify that line's

-	end point to avoid the distortion.

-

-	Some glyphs in the bug report font (TexGyreHeros-Regular) that show

-	the change are:

-

-	  25ppem    S (98)

-	  24ppem    eight (52)

-	  25.5ppem  p (85)

-

-	Curves at the *end* of a subpath are no longer distorted.  However,

-	some of these glyphs have bad hint substitutions in the middle of a

-	subpath, and these are not affected.

-

-	The patch has been tested with a set of 106 fonts that shipped with

-	Adobe Creative Suite 4, together with 756 Open Source CFF fonts from

-	Google Fonts.  There are 1.5 million glyphs, of which some 20k are

-	changed with the fix.  A sampling of a few hundred of these changes

-	have been examined more closely, and the changes look good (or at

-	least acceptable).

-

-	* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'

-	to indicate that we synthesize a closepath line.

-

-	* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.

-	(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for

-	`lineto' operator) and adjust hint zone.

-	For synthesized closing lines, use end point in first hint zone.

-	(cf2_glyphpath_lineTo): Take care of synthesized closing lines.  In

-	particular, shift the detection of zero-length lines from character

-	space to device space.

-	(cf2_glyphpath_closeOpenPath): Remove assertion.

-	Updated.

-2013-08-25  Werner Lemberg  <[email protected]>

-

-	[autofit] Introduce data file for blue strings.

-

-	The idea is to have a central file which gets processed by a Perl

-	script to create proper `.c' and `.h' files using templates.  There

-	are two other reasons to do that:

-

-	  . The data file should be easily readable.  We use UTF-8 encoding

-	    which then gets converted to single bytes.

-

-	  . Since the number of supported scripts will increase soon, the

-	    current usage of blue string arrays is a waste of space.  Using

-	    the Perl script it is possible to imitate jagged arrays,

-	    defining enumeration constants as offsets into the arrays.

-

-	This commit only adds files without changing any functionality.

-

-	* src/autofit/afblue.dat: New data file.

-	* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

-

-	* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files

-	Points which are very near to each other are now marked as such.

-	The `weak' flag is then computed by using the `in' vector of the

-

-	Speed up ARMv7 support.

-

-	When building for ARMv7 with thumb2 instructions, the optimized

-	`FT_MulFix_arm' assembly routine was not being used.

-

-	The reason for this is in the `ftconfig.h' header, namely:

-

-	- The assembly routine uses the `smull' instruction which is not

-	  available when generating Thumb-1 machine code.  It is available

-	  in Thumb-2 mode, though.

-

-	- The header was written a long time ago before Thumb-2 became

-	  widely popular (e.g. with Android).  So it simply doesn't use the

-	  assembly routine if the `__thumb__' built-in macro is defined.

-

-	- When compiling in Thumb-2 mode, the compiler will define both

-	  `__thumb__' and `__thumb2__'.

-

-	By checking for `(__thumb2__ || !__thumb__)', we ensure that the

-	assembly routine is only avoided when generating Thumb-1 code.

-

-	Given that this is performance-sensitive function, this improves

-	`ftbench' as follows on a Galaxy Nexus:

-	FT_LibraryRec): Make `refcount' a signed integer.  If, for example,

-	FT_Open_Face() fails in a memory allocation before the face's

-	reference count is set to 1, a subsequent `FT_Done_Library' call

-	would otherwise loop over `FT_Done_Face' 2^32 times before freeing

-	the face.

-

-	* src/base/ftobjs.c (open_face): Initialize `stream' and friends

-	earlier.

-	(FT_Open_Face) <Fail>: Behave correctly if `node' is NULL.

-

-	This code, present since eight(!) years in the unused `CACHE'

-

-	Apply fixes for cppcheck nitpicks.

-

-	  https://cppcheck.sourceforge.net/

-

-	The call was (from the top-level of the FreeType tree):

-

-	           -I include \

-	           -I include/freetype/ \

-	           -I include/freetype/internal/ \

-	           . &> cppcheck.log

-

-	Note that the current version heavily chokes on FreeType, delivering

-	many wrong results.  I will report those issues to the cppcheck team

-	so that a newer version gives improved results hopefully.

-

-	which defines two new SFNT tables, `CBDT' and `CBLC' (named and

-	modeled after `EBDT' and `EBLC', respectively).  The color bitmaps

-	are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA

-	pre-multiplied sRGB images.  If PNG support is available, PNG color

-

-	[mac] Fix ftexport.sym target in Jamfile.

-

-	* Jamfile: Update the directories of the header files scanned for

-	ftexport.sym.  They were incorrect since the migration of the

-	header files, on 2015-06-22.  Either inexisting include/cache

-	(removed on 2006-03-20) is not needed to be listed explicitly.

-	Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.

-

-	[smooth] Sub-banding protocol revision.

-

-	Rasterization sub-banding is utilized at large sizes while using a

-	rather small fixed memory pool.  Indeed it is possible to make an

-	educated guess how much memory is necessary at a given size for a

-	given glyph.  It turns out that, for a large majority of European

-	glyphs, you should store about 8 times more boundary pixels than

-	their height.  Or, vice versa, if your memory pool can hold 800

-	pixels the band height should be 100 and you should sub-band

-	anything larger than that.  Should you still run out of memory,

-	FreeType bisects the band but you have wasted some time.  This is

-	what has been implemented in FreeType since the beginning.

-

-	It was overlooked, however, that the top band could grow to twice

-	the default band size leading to unnecessary memory overflows there.

-	This commit fixes that.  Now the bands are distributed more evenly

-	and cannot exceed the default size.

-

-	Now the magic number 8 is really suitable for rather simple European

-	scripts.  For complex Chinese logograms the magic number should be

-	13 but that is subject for another day.

-

-	* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding

-	protocol.

-

-2016-07-07  suzuki toshiya  <[email protected]>

-

-	[mac] Fix Savannah bug #48417.

-

-	Mac OS X linker throws errors when `-exported_symbol_list' input

-	file includes non-existing symbols.  Reported by Ryan Schmidt.

-

-	* builds/exports.mk: Exclude ftmac.h from the headers for apinames

-	by default.  Include it when ftmac.c would be compiled.

-

-2016-07-06  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttinterp.c (TInstruction_Function): Removed, unused.

-

-2016-07-04  Werner Lemberg  <[email protected]>

-

-	[autofit] Handle single-point contours as segments.

-

-	Doing so allows us to link them to edges – some fonts like

-	`NotoSansGurmukhi-Regular' have such isolated points sitting exactly

-	on other outlines.

-

-	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't

-	ignore one-point contours but handle them specially as one-point

-	segments.

-

-	* src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some

-	fields to `TCoord'.

-	(gray_find_cell, gray_render_scanline, gray_render_line, gray_hline,

-	gray_sweep, gray_convert_glyph): Updated.

-

-2016-06-28  Alexei Podtelezhnikov  <[email protected]>

-	(gray_convert_glyph): ... to here and update accordingly.

-

-2016-06-22  Alexei Podtelezhnikov  <[email protected]>

-

-	[smooth] Consolidate boundary checks.

-

-	Removing the checks from `gray_hline' shaves 1% off rendering speed.

-

-	* src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_MIN' and `FT_MAX'.

-	(gray_TWorker): No need to store `clip_box'.

-	(gray_hline): Remove unnecessary boundary checks.

-

-2016-06-09  David Capello  <[email protected]>

-

-	[cmake] Avoid modifying `ftconfig.h' and `ftoption.h' files.

-

-	* CMakeLists.txt: Each time cmake is run those files are

-	modified and the whole FreeType library is recompiled.  With this

-	we can avoid recompilations.

-

-2016-06-09  Werner Lemberg  <[email protected]>

-

-

-2016-06-07  Werner Lemberg  <[email protected]>

-

-	[autofit] Fix compilation with VS2016 (#48126).

-

-	This compiler doesn't recognize the end-of-comment sequence `*/' if

-	it immediately follows non-ASCII characters.

-

-	* src/autofit/afscript.h: Ensure whitespace before `*/'.

-

-2016-06-04  Werner Lemberg  <[email protected]>

-

-	Fix a test for named instances (#48122).

-

-	This was missed while giving negative face indices an extended

-	meaning.

-

-	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement.

-

-2016-05-31  Nikolaus Waxweiler  <[email protected]>

-

-	[truetype] Let SHPIX move points in the twilight zone in v40.

-

-	* src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in

-	the twilight zone.  Otherwise, treat SHPIX the same as DELTAP.

-	Unbreaks various fonts such as older versions of Rokkitt and DTL

-	Argo T Light that would glitch severely after calling ALIGNRP after a

-	blocked SHPIX.

-

-2016-05-30  Werner Lemberg  <[email protected]>

-

-	[type42] Support `CharStrings' entry format as created by LilyPond.

-

-	* src/type42/t42parse.c (t42_parse_charstrings): Handle entries

-	having the format

-

-	  (foo) cvn 12345 def

-

-2016-05-28  Werner Lemberg  <[email protected]>

-

-	* src/autofit/afranges.c: Remove `UL' postfix from hex numbers.

-

-	Suggested by Alexei.  `UL' is only needed for 16bit compilers, but

-	it seems noone is using this anymore (and we no longer test whether

-	FreeType compiles in such an environment).  Otherwise, it is easy to

-	add the postfix to the `AF_UNICODE_RANGE' macro.

-

-2016-05-26  Alexei Podtelezhnikov  <[email protected]>

-

-	[smooth] Shrink bisection stack.

-

-	The convergence of Bézier flatteners is fast with the deviation

-	from straight line being asymptotically cut 4-fold on each bisection.

-	This justifies smaller bisection stack size.

-

-	* src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.

-	(gray_render_conic): Create and use conic `bez_stack'. Move back the

-	band analysis from...

-	(gray_conic_to): ... here.

-	(gray_render_cubic): Create and use cubic `bez_stack'. Move back the

-	band analysis from...

-	(gray_cubic_to): ... here.

-	(gray_move_to): Updated.

-

-2016-05-25  Werner Lemberg  <[email protected]>

-

-	[autofit] Fixes for Armenian and Gujarati ranges.

-

-	* src/autofit/afranges.c (af_armn_uniranges): Corrected.

-	(af_guru_nonbase_uniranges): Make U+0A3E a base character.

-

-2016-05-24  Werner Lemberg  <[email protected]>

-

-	[autofit] Add support for Armenian script.

-

-	* src/autofit/afblue.dat: Add blue zone data for Armenian.

-

-	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

-

-	* src/autofit/afscript.h: Add Armenian standard characters.

-

-	* src/autofit/afranges.c: Add Armenian data.

-

-	* src/autofit/afstyles.h: Add Armenian data.

-

-2016-05-23  Werner Lemberg  <[email protected]>

-

-	* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.

-

-	This was commented about 10 years ago – I think the reason then to

-	disable libtool's `-export-symbols' option was to give some badly

-	programmed applications access to internal FreeType functions.

-

-	I believe that we should no longer take care of such programs; the

-	number of symbols exported should be rather restricted as much as

-	possible.

-

-2016-05-22  Werner Lemberg  <[email protected]>

-

-	[autofit] Add blue-zone support for Gurmukhi script.

-

-	This essentially moves the Gurmukhi script from the `Indic' hinter to

-	the `Latin' hinter.

-

-	* src/autofit/afblue.dat: Add blue zone data for Gurmukhi.

-

-	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

-

-	* src/autofit/afscript.h: Add Gurmukhi standard characters and move

-	data out of AF_CONFIG_OPTION_INDIC block.

-

-	* src/autofit/afranges.c: Move Gurmukhi data out of

-	AF_CONFIG_OPTION_INDIC block.

-

-	* src/autofit/afstyles.h: Update Gurmukhi data; in particular, use

-	AF_WRITING_SYSTEM_LATIN.

-

-2016-05-21  Werner Lemberg  <[email protected]>

-

-	Minor clang++ fixes.

-

-	* src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c

-	(ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add

-	initializer.

-

-	* src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit

-	conversion from NULL to boolean.

-

-2016-05-21  Werner Lemberg  <[email protected]>

-

-	Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955).

-

-	* include/freetype/internal/ftmemory.h (cplusplus_typeof): Use

-

-	A single decrement counter of segments to draw, instead of an array,

-

-	[cmake] Honor SKIP_INSTALL_* settings (as used in zlib).

-

-	As FreeType depends on zlib, if we don't install zlib (e.g., because

-	we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too

-	(cmake triggers an error saying that FreeType cannot be installed

-	because zlib target isn't in the export set).

-

-	* CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS',

-

-	[autofit] Add support for Georgian scripts.

-

-	Georgian is problematic, since `uppercase' forms of Mkhedruli

-	(called Mtavruli) are not yet defined in Unicode, which means that

-	proper blue zones can't be defined.  However, there is already a

-	proposal submitted to Unicode; see

-

-	  https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf

-

-	Additionally, due to historical reasons, Unicode treats Khutsuri as

-	the same script as Mkhedruli, and so does OpenType.  However, since

-	the two scripts have completely different shapes it can happen that

-	blue zones differ considerably.  The tag `geok' used here (derived

-	from ISO 15924) to differentiate the two scripts is not an OpenType

-	tag in use.  If we now have a font that contains both glyphs for

-	Mkhedruli and Khutsuri, and it uses OpenType features for both also,

-	HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,

-	blue zones for `geok' are not used for glyphs involved in the

-	OpenType features.

-

-	An issue not yet resolved is which OpenType feature should be used

-	to access Mtavruli glyph shapes; right now, FreeType doesn't set up

-	support for them, but it is easy to add them later on as soon as

-	more information is available.

-

-	* src/autofit/afblue.dat: Add blue zone data for Georgian.

-2016-04-05  Werner Lemberg  <[email protected]>

-

-	[autofit] Provide dummy blue zone for pseudo script `none'.

-

-	Even if the dummy hinter is used as the handler for `none' (which

-	doesn't use blue zones), it is more consistent than the old value

-	(which was 0), pointing to Arabic...

-

-	* src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'.

-	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

-

-	* src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE.

-

-	[pfr] Robustify bitmap strike handling (#47514).

-

-	We did a binary search for a charcode without ensuring that the

-

-	[autofit] Fix handling of default script.

-

-	Patch taken from ttfautohint, commit

-	071ae2c00e0d67f9d19418f4fade1c23d27dc185.

-

-	There were two bugs.

-

-	  - We now use non-standard script tags like `khms' for special

-	    purposes.  However, HarfBuzz maps such tags to `DFLT', and

-	    without this commit the associated lookups were incorrectly

-	    assigned to the non-standard tags.

-

-	  - Let's assume we have a Bengali font, and the font's `DFLT'

-	    script tag handles the necessary lookups for Bengali, too.

-	    Without this commit, the `DFLT' lookups were assigned to

-	    ttfautohint's default script (usually `latn') before the

-	    standard lookups for Bengali were handled.

-

-	    We now have the following order while searching for covered

-	    glyph indices.

-

-	      special features of scripts (e.g. `sups' for Cyrillic)

-	      Unicode mappings of scripts

-	      remaining features of scripts (especially important for Indic

-	        scripts)

-	      default features of default script

-

-	* src/autofit/afshaper.c, src/autofit/afshaper.h

-	(af_shaper_get_coverage): Add boolean parameter to indicate default

-	script.

-	Update all callers.

-

-	* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):

-	Fix search order for coverages.

-

-2015-12-09  Werner Lemberg  <[email protected]>

-

-	[autofit] Introduce subscript top blue zones.

-

-	This feature is mainly for Khmer: The idea is to avoid a clash

-	between the top of subscript glyphs and the bottom of normal

-	baseline glyphs.

-

-	This only works for character clusters mapped to multiple glyphs.

-

-	* src/autofit/afblue.dat: Add subscript top blue zone for Khmer.

-

-2015-12-06  Werner Lemberg  <[email protected]>

-

-	* src/autofit/afblue.dat: Add blue zone data for Khmer.

-

-2015-12-06  Werner Lemberg  <[email protected]>

-

-	[autofit] Rewrite HarfBuzz interface to support character clusters.

-

-	Scripts like Khmer have blue zones that can't be directly

-	represented by Unicode characters.  Instead, it is necessary to let

-	HarfBuzz convert character clusters into proper glyph representation

-	forms, then deriving the blue zone information from the resulting

-	glyphs.

-

-	* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...

-	* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new

-	files, providing a new API to access HarfBuzz.

-

-	The new API manages a HarfBuzz buffer with `af_shaper_buf_create'

-	and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded

-	string with function `af_shaper_get_cluster', and the resulting

-	glyph data (indices, advance widths, vertical offsets) can be

-	iteratively accessed with function `af_shaper_get_elem'.

-

-	* src/autofit/afcjk.c (af_cjk_metrics_init_widths,

-	af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

-	(AF_ScriptClassRec): Replace `standard_char[123]' with

-	`standard_charstring'.

-	of the `SCRIPT' calls with a string parameter, holding the standard

-	characters (in UTF-8 encoding) separated with spaces.

-	src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c

-	a constructed tarball should contain a font file as the first

-	element, and files to be attached as further elements.

-	[sfnt] Better checks for invalid cmaps (2/2) (#46019).

-

-	While the current code in `FT_Get_Next_Char' correctly rejects

-	out-of-bounds glyph indices, it can be extremely slow for malformed

-	cmaps that use 32bit values.  This commit tries to improve that.

-

-	* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,

-	tt_cmap12_char_map_binary, tt_cmap13_next,

-	tt_cmap13_char_map_binary): Reject glyph indices larger than or

-

-	[sfnt] Improve handling of invalid SFNT table entries (#45987).

-

-	This patch fixes weaknesses in function `tt_face_load_font_dir'.

-

-	- It incorrectly assumed that valid tables are always at the

-	  beginning.  As a consequence, some valid tables after invalid

-	  entries (which are ignored) were never seen.

-

-	- Duplicate table entries (this is, having the same tag) were not

-	  rejected.

-

-	- The number of valid tables was sometimes too large, leading to

-	  access of invalid tables.

-

-	* src/sfnt/ttload.c (check_table_dir): Add argument to return number

-	of valid tables.

-	Add another tracing message.

-	(tt_face_load_font_dir): Only allocate table array for valid

-	entries as returned by `check_table_dir'.

-	Reject duplicate tables and adjust number of valid tables

-	accordingly.

-

-	* src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak.

-

-	(ft_gzip_get_uncompressed_file): Correct byte order while reading

-	unsigned long value.  Without this change, the whole optimization of

-	accessing small files in `FT_Stream_OpenGzip' is never executed!  As

-2015-09-04  Werner Lemberg  <[email protected]>

-

-	[autofit] Redesign code ranges (1/2).

-

-	This patch introduces auxiliary code ranges that identify no-base

-	characters; they refer to glyphs of a script that should be hinted

-	without alignments to blue zones (mostly diacritics).

-

-	It also splits off ranges for fallback scripts that handle subscript

-	and superscript characters not covered by OpenType features.  For

-	example, this greatly helps improve the hinting of various phonetic

-	alphabets, which contain a large amount characters that look like

-	superscript glyphs.

-

-	Finally, code ranges are updated to Unicode 8.0, and enclosed

-	characters are removed in general since they normally look better if

-	they stay unhinted.

-

-	* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode

-	8.0.

-	Split off superscript-like and subscript-like glyphs into...

-

-	(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.

-

-	(af_xxxx_nobase_uniranges): New arrays that hold no-base characters

-	of the corresponding character ranges.

-2015-08-13  Werner Lemberg  <[email protected]>

-

-	[truetype] Introduce named instance access to GX fonts.

-

-	For functions querying a face, bits 16-30 of the face index can hold

-	the named instance index if we have a GX font.  The indices start

-	with value 1; value 0 indicates font access without GX variation

-	data.

-

-	* include/freetype/freetype.h (FT_FaceRec): Update documentation.

-

-2015-08-08  Werner Lemberg  <[email protected]>

-

-	[type42] Fix glyph access.

-

-	This is a severe bug: We've missed one level of indirection, as

-	described in the Type 42 specification.  As a result, ftview

-	sometimes showed incorrect glyphs for given glyph names, and even

-	displayed `error 0x0006' (invalid argument!) in case the number of

-	glyph indices differed between the Type 42 font and the embedded

-	TTF.

-

-	Apparently, noone ever noticed it; this shows how much Type 42 fonts

-	are in use...

-

-	* src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index

-	to embedded TTF's glyph index.

-

-

-	[type42] Parse FontMatrix according to specifications.

-

-	* src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix

-	does not need scaling by 1000. Units_per_EM are taken from the

-	embedded TrueType.

-

-2015-08-06  Werner Lemberg  <[email protected]>

-

-	[autofit] Improve Arabic hinting.

-

-	Problem reported by Titus Nemeth <[email protected]> (by using

-

-2015-08-04  Werner Lemberg  <[email protected]>

-

-	Another left-shift bug (#45681).

-

-2015-08-03  Alexei Podtelezhnikov  <[email protected]>

-

-	[base] Fix `ft_corner_orientation'.

-

-	Remove casting from `FT_Long' to `FT_Int' that might change the sign

-	of the return value and make it faster too.

-

-	* src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay

-	with 32-bit arithmetic when safe. Use plain math on 64-bit systems.

-	* src/pshinter/pshalgo.c: Remove old unused code.

-

-	* src/pfr/pfrgload.c (pfr_glyph_load_compound): Use multiplication,

-	not left-shift.

-

-	Fix Savannah bug #45097.

-

-2015-05-31  Werner Lemberg  <[email protected]>

-

-	[truetype] In GX, make private point numbers work correctly.

-

-	This is completely missing in Apple's documentation: If a `gvar'

-	tuple uses private point numbers (this is, deltas are specified for

-	some points only), the uncovered points must be interpolated for

-	this tuple similar to the IUP bytecode instruction.  Examples that

-	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.

-

-	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,

-	tt_handle_deltas): New functions.

-	(TT_Vary_Get_Glyph_Deltas): Renamed to...

-	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the

-	points and does no longer return an array of deltas.

-	Add tracing information.

-	Call `tt_handle_deltas' to interpolate missing deltas.

-	Also fix a minor memory leak in case of error.

-

-	* src/truetype/ttgxvar.h: Updated.

-

-	* src/truetype/ttgload.c (TT_Process_Simple_Glyph,

-	load_truetype_glyph): Updated.

-	ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,

-	TT_Set_Var_Design, tt_face_vary_cvt): Do it.

-	[truetype] Fix commit from 2015-05-22.

-

-	* src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code

-2015-05-23  Werner Lemberg  <[email protected]>

-

-	[truetype] Fix return values of GETINFO bytecode instruction.

-

-	* src/truetype/ttinterp.h (TT_ExecContextRec): New fields

-	`vertical_lcd' and `gray_cleartype'.

-

-	* src/truetype/ttgload.c (tt_loader_init): Initialize new fields.

-	Change `symmetrical smoothing' to TRUE, since FreeType produces

-	exactly this.

-

-	* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit

-	values for symmetrical smoothing, namely 11/18.

-	Handle bits for vertical LCD subpixels (8/15) and Gray ClearType

-	(12/19).

-

-2015-05-23  Werner Lemberg  <[email protected]>

-

-	[truetype] Minor.

-

-	* src/truetype/ttinterp.h (TT_ExecContext):

-	 s/subpixel/subpixel_hinting.

-

-	* src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.

-

-2015-05-22  Werner Lemberg  <[email protected]>

-

-	[truetype] Support selector index 3 of the INSTCTRL instruction.

-

-	This flag activates `native ClearType hinting', disabling backward

-	compatibility mode as described in Greg Hitchcocks whitepaper.  In

-	other words, it enables unrestricted functionality of all TrueType

-	instructions in ClearType.

-

-	* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'

-	unconditionally.

-	(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of

-	`GS.instruct_control' is active.

-

-	* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.

-	argument.

-

-2015-05-17  Werner Lemberg  <[email protected]>

-

-	[truetype] Fix loading of composite glyphs.

-

-	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the

-	ARGS_ARE_XY_VALUES flag is not set, handle argument values as

-	unsigned.  I trust `ttx' (which has exactly such code) that it does

-	the right thing here...

-

-	The reason that noone has ever noticed this bug is probably the fact

-	that point-aligned subglyphs are rare, as are subglyphs with a

-	number of points in the range [128;255], which is quite large (or

-	even in the range [32768;65535], which is extremely unlikely).

-

-2015-05-12  Chris Liddell  <[email protected]>

-

-	[cff] Make the `*curveto' operators more tolerant.

-

-	* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes

-	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,

-	pulling values off the stack until the stack is exhausted.

-	Implicitly the stack must be a multiple (or for subtly different

-	behaviour) a multiple plus a specific number of extra values deep.

-	If that's not the case, enforce it (as the old code did).

-

-2015-05-12  Chris Liddell  <[email protected]>

-

-	[cff] fix incremental interface with new cff code.

-

-	* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental

-	interface to retrieve glyph data for a SEAC, it be left to the

-	incremental interface callback to apply the encoding to raw

-	character index (as it was in the previous code).

-

-	[cff] Use `name' table for PS name if we have a SFNT-CFF.

-

-	This follows the OpenType 1.7 specification.  See

-

-	  https://tug.org/pipermail/tex-live/2015-April/036634.html

-

-	for a discussion.

-

-	[raster] Fix Savannah bug #44022.

-

-	Add fallback for glyphs with degenerate bounding boxes.

-

-	If a glyph has only one very narrow feature, the bbox can end up

-	with either the width or height of the bbox being 0, in which case

-	no raster memory is allocated and no attempt is made to render the

-	glyph.  This is less than ideal when the drop-out compensation in

-	the rendering code would actually result in the glyph being

-	rendered.

-

-	This problem can be observed with the `I' glyph (gid 47) in the

-	Autodesk RomanS TrueType font.

-

-	* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either

-	dimension is zero to explicitly round up/down (instead of simply

-	round).

-

-2015-01-17  Werner Lemberg  <[email protected]>

-

-	* src/tools/update-copyright-year: New Perl script.

-	* src/tools/update-copyright: New shell script that calls

-

-	* src/autofit/afmodule.c (af_autofitter_load_glyph): Use local

-	`hints' object.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[autofit] Reuse slot glyph loader.

-

-	No need to create a new glyph loader; we can reuse the one from

-	`slot->internal->loader'.  It's hard to tell why it was written that

-	way originally, but new code looks sound and correct to me, and

-	avoids lots of allocations.

-

-	* src/autofit/afloader.c (af_loader_init): Change return type to

-	`void'.

-	Don't call `FT_GlyphLoader_New'.

-	(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.

-	(af_loader_load_g): Update code to use `internal->loader', which

-	doesn't need copying of data.

-

-	* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.

-	Update prototype.

-

-	* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[autofit] Remove (unused) support for composite glyphs.

-

-	We never have to deal with composite glyphs in the autohinter, as

-	those will be loaded into FORMAT_OUTLINE by the recursed

-	`FT_Load_Glyph' function.

-

-	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply

-	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies

-	FT_LOAD_NO_HINTING:

-

-	  /* resolve load flags dependencies */

-

-	  if ( load_flags & FT_LOAD_NO_RECURSE )

-	    load_flags |= FT_LOAD_NO_SCALE         |

-	                  FT_LOAD_IGNORE_TRANSFORM;

-

-	  if ( load_flags & FT_LOAD_NO_SCALE )

-	  {

-	    load_flags |= FT_LOAD_NO_HINTING |

-	                  FT_LOAD_NO_BITMAP;

-

-	    load_flags &= ~FT_LOAD_RENDER;

-	  }

-

-	and as such the auto-hinter is never called.  Thus, the recursion in

-	`af_loader_load_g' never actually happens.  So remove the depth

-	counter as well.

-

-	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'

-	parameter.

-	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.

-	(af_loader_load_glyph): Updated.

-

-	[raster] Fix uninitialized memory access.

-

-	Apparently `ras.cProfile' might be uninitialized.  This will be the

-	case if `ras.top == ras.cProfile->offset', as can be seen in

-	`End_Profile'.  The overshoot code introduced in a change `Fix B/W

-	rasterization of subglyphs with different drop-out modes.' (from

-	2009-06-18) violated this, accessing `ras.cProfile->flags'

-	unconditionally just before calling `End_Profile' (which then

-	detected that `cProfile' is uninitialized and didn't touch it).

-

-	This was harmless, and was not detected by valgrind before because

-	the objects were allocated on the `raster_pool', which was always

-	initialized.  With recent change to allocate raster buffers on the

-	stack, valgrind now reported this invalid access.

-

-	* src/raster/ftraster.c (Convert_Glyph): Don't access an

-	uninitialized `cProfile'.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[smooth] Fix uninitialized memory access.

-

-	Looks like `ras.span_y' could always be used without initialization.

-	This was never detected by valgrind before because the library-wide

-	`raster_pool' was used for the worker object and `raster_pool' was

-	originally zero'ed.  But subsequent reuses of it were using `span_y'

-	uninitialized.  With the recent change to not use `render_pool' and

-	allocate worker and buffer on the stack, valgrind now detects this

-	uninitialized access.

-

-	* src/smooth/ftgrays.c (gray_raster_render): Initialize

-	`ras.span_y'.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[base] Don't initialize unused `driver->glyph_loader'.

-

-	* src/base/ftobjs.c (Destroy_Driver): Don't call

-	`FT_GlyphLoader_Done'.

-	(FT_Add_Module): Don't call `FT_GlyphLoader_New'.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[base] Don't allocate `library->raster_pool' anymore.

-

-	It's unused after the following commits:

-

-	  [raster] Allocate render pool for mono rasterizer on the stack.

-	  [raster] Remove 5-level gray AA mode from monochrome rasterizer.

-

-	The value of FT_RENDER_POOL_SIZE still serves the purpose it used to

-	serve, which is, to adjust the pool size.  But the pool is now

-	allocated on the stack on demand.

-

-	* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[base] Do not reorder library->renderers upon use.

-

-	Instead of keeping `library->renderers' in a MRU order, just leave

-	it as-is.  The MRU machinery wasn't thread-safe.

-

-	With this patch, rasterizing glyphs from different faces from

-	different threads doesn't fail choosing rasterizer

-	(FT_Err_Cannot_Render_Glyph).

-

-	Easiest to see that crash was to add a `printf' (or otherwise let

-	thread yield in FT_Throw with debugging enabled).

-

-	* src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c

-	(FT_Outline_Render): Don't call `FT_Set_Renderer'.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[raster] Allocate render pool for mono rasterizer on the stack.

-

-	Instead of using the `render_pool' member of `FT_Library' that is

-	provided down to the rasterizer, completely ignore that and allocate

-	needed objects on the stack instead.

-

-	With this patch, rasterizing glyphs from different faces from

-	different threads doesn't crash in the monochrome rasterizer.

-

-	* src/raster/ftraster.c (black_TRaster): Remove `buffer',

-	`buffer_size', and `worker' members.

-

-	(ft_black_render): Create `buffer' locally.

-	(ft_black_reset): Updated.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[raster] Remove 5-level gray AA mode from monochrome rasterizer.

-

-	It was off by default and couldn't be turned on at runtime.  And the

-	smooth rasterizer superseded it over ten years ago.  No point in

-	keeping.  Comments suggested that it was there for compatibility

-	with FreeType 1.

-

-	550 lines down.

-

-	* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,

-	RASTER_GRAY_LINES): Remove macros and all associated code.

-

-	(black_TWorker): Remove `gray_min_x' and `gray_max_x'.

-	(black_TRaster): Remove `grays' and `gray_width'.

-	ft_black_render): Updated.

-

-	* src/raster/ftrend1.c (ft_raster1_render): Simplify code.

-	(ft_raster5_renderer_class): Removed.

-

-2015-01-14  Behdad Esfahbod  <[email protected]>

-

-	[smooth] Allocate render pool for smooth rasterizer on the stack.

-

-	Instead of using the `render_pool' member of `FT_Library' that is

-	provided down to the rasterizer, completely ignore that and allocate

-	needed objects on the stack instead.

-

-	With this patch, rasterizing glyphs from different faces from

-	different threads doesn't crash in the smooth rasterizer.

-

-	[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.

-

-	Previously the code had stipulation for using a per-TT_Size exec

-	context if `size->debug' was true.  But there was no way that

-	`size->debug' could *ever* be true.  As such, the code was always

-	using the singleton `TT_ExecContext' that was stored in `TT_Driver'.

-	This was, clearly, not threadsafe.

-

-	With this patch, loading glyphs from different faces from different

-	threads doesn't crash in the bytecode loader code.

-

-	* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.

-	(TT_DriverRec): Remove `context' member.

-

-	* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove

-

-	[autofit] Allocate AF_Loader on the stack instead of AF_Module.

-

-	Stop sharing a global `AF_Loader'.  Allocate one on the stack during

-	glyph load.

-

-	Right now this results in about 25% slowdown, to be fixed in a

-

-	With this patch loading glyphs from different faces from different

-	[gzip] Improve building with external zlib (#49673).

-

-	Building FreeType with external zlib 1.2.8 makes msvc 14 stop with

-	the following error.

-

-	  ftgzip.c

-	  zlib-1.2.8\zlib.h(86): error C2061:

-	                         syntax error: identifier 'z_const'

-	  zlib-1.2.8\zlib.h(94): error C2054:

-	                          error count exceeds 100; stopping compilation

-

-	The error happens because FreeType keeps an own copy of zlib-1.1.4

-	under `src/gzip'.  When building `src/gzip/ftgzip.c' with

-	FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses

-

-	  #include <zlib.h>

-

-	which correctly finds an external `zlib.h', but `zlib.h' itself has

-	a line

-

-	  #include "zconf.h"

-

-	which makes Visual Studio 2015 find `src/gzip/zconf.h' while

-	compiling the files in `src/gzip'.

-

-	* src/gzip/zconf.h: Rename to...

-	* src/gzip/ftzconf.h: ... this.

-	    Werner Lemberg  <[email protected]>

-

-	Introduce a way of quickly retrieving (embedded) bitmap metrics.

-

-	`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph

-

-	* src/base/ftobjs.c (FT_Open_Face): Check whether negation was

-2016-09-01  Alexei Podtelezhnikov  <[email protected]>

-

-	[smooth] Simplify span rendering more.

-

-	It turns out that there is significant cost associated with `FT_Span'

-	creation and calls to `gray_render_span' because it happens so

-	frequently. This removes these steps from our internal use but leaves

-	it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain

-	is about 5%.

-

-	* src/smooth/ftgrays.c (gray_render_span): Removed. The code is

-	migrated to...

-	(gray_hline): ... here.

-

-2016-08-30  Alexei Podtelezhnikov  <[email protected]>

-

-	[smooth] Streamline pixmap drawing a bit more.

-

-	Zero coverage is unlikely (1 out of 256) to warrant checking. This

-	gives 0.5% speed improvement in rendering simple glyphs.

-

-	* src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.

-

-2016-08-29  Alexei Podtelezhnikov  <[email protected]>

-	(gray_TWorker): ... here.

-	(gray_raster_render): .. to here.

-

-

-	This removes unnecessary complexity of span merging and buffering.

-

-	* src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed.

-	(gray_TWorker): Remove span buffer and related fields.

-	(gray_sweep, gray_hline): Updated.

-

-	[truetype] Fix `MPS' instruction.

-

-2016-08-06  Jon Spencer  <[email protected]>

-

-	[sfnt] Fix `FT_Get_Advance' for bitmap strikes.

-

-	`FT_Get_Advance' returns 0 for bitmap fonts.  It first gets the

-	advance value from the font table and then scales it by the

-	`font->size->metrics->x_scale' field.  But `FT_Select_Size' doesn't

-	set that value for bitmap fonts and the advance gets scaled to zero.

-

-	* src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust

-	`maxComponentDepth'.

-	* src/truetype/ttgload.c (load_truetype_glyph): Don't abort if

-

-2016-07-22  Hin-Tak Leung  <[email protected]>

-

-	[truetype] Record the end of IDEFs.

-

-	To match the logic in FDEF.  The value of the end is only used for

-

-	This commit implements undocumented (but confirmed) stuff from

-	Apple's old bytecode engine.

-

-	  GETVARIATION[], opcode 0x91

-	    This opcode pushes normalized variation coordinates for all axes

-	    onto the stack (in 2.14 format).  Coordinate of first axis gets

-	    pushed first.

-

-	  GETINFO[], selector bit 3

-	    If GX variation support is enabled, bit 10 of the result is set

-	    to 1.

-

-	* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.

-	(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.

-	[truetype] Make all glyphs in `Zycon' GX font work.

-

-	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary

-	tests.

-

-2016-07-16  Werner Lemberg  <[email protected]>

-

-	[truetype] Fix GX delta tracing.

-

-	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace

-	relative point movements.

-

-2016-07-16  Behdad Esfahbod  <[email protected]>

-

-	[truetype] More fixes for GX.

-

-	This finally fixes the rendering of the cyclist and the lizard in

-	the `Zycon' font.

-

-	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point

-	index is always cumulative.

-

-	(tt_handle_deltas): Rename to...

-	(tt_interpolate_deltas): ... This.

-	Add new parameter for output point array.

-	Update caller.

-

-	(TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds

-	the intermediate results of `tt_interpolate_deltas' that are to be

-	added to `outline->points'.

-

-2016-07-15  Werner Lemberg  <[email protected]>

-

-	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.

-

-	`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.

-

-	Reported by Alexei.

-

-2016-07-16  Nikolaus Waxweiler  <[email protected]>

-

-	* src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.

-

-	Problem reported by Hin-Tak Leung.

-

-2016-07-15  Werner Lemberg  <[email protected]>

-

-	[autofit] Update and improve segment and edge tracing.

-

-	* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace

-	`delta' also.

-	Don't show first point of segment as a replacement for `pos'; this

-	is (a) misleading, since the difference to `pos' can be almost

-	arbitrarily large in corner cases, and (b) it is better to have all

-	segment data in font units instead of a single value given in output

-	space coordinates.

-	Improve layout.

-	(af_glyph_hints_dump_edges): Show px->units and units->px conversion

-	values for convenience.

-	Improve layout.

-

-2016-07-15  Werner Lemberg  <[email protected]>

-

-	[autofit] For edges, reject segments wider than 1px (#41334).

-

-	* src/autofit/afhints.h (AF_SegmentRec): New member `delta'.

-

-	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute

-	`delta'.

-	(af_latin_hints_compute_edges): Reject segments with a delta larger

-	than 0.5px.

-

-2016-07-14  Werner Lemberg  <[email protected]>

-

-	* include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.

-	* src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits.

-

-2016-07-14  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.

-

-2016-07-14  Behdad Esfahbod  <[email protected]>

-

-	[truetype] Fix gxvar delta interpolation.

-

-	The coordinates of the base font should be used for interpolation

-	purposes, NOT the current points (i.e., the result of accumulation

-	of previous deltas).

-

-	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize

-	`points_org' before looping over all tuples.

-	Provide values in font units.

-

-2017-09-08  suzuki toshiya  <[email protected]>

-

-	[base] Remove a check for resource ID in the resource fork driver.

-

-	LastResort.dfont has a marginal resource ID 0xFFFF for sfnt

-	resource.  Inside Macintosh: More Macintosh Toolbox, `Resource IDs'

-	(1-46), tells that some IDs are reserved and should not be used.

-	FreeType2 just uses resource ID to sort the fragmented resource.

-	To accept the marginal fonts, the checking is removed.

-

-	* src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id

-	validity check, fix a trace message format.

-

-2017-09-08  suzuki toshiya  <[email protected]>

-

-	[sfnt, truetype] Register the tags for marginal fonts.

-

-	The first 32bit of standard TrueType variants is 0x00010000,

-	`OTTO', `ttcf', `true' or `typ1'.  2 marginal dfonts on legacy Mac

-	OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources

-	starting 0xA5 followed by `kbd' or `lst'.  Considering the following

-	data could be parsed as conventional TrueType fonts, the header

-	checking is updated to allow these tags.  It seems that recent Mac

-	OS X has already switched to normal TTF for these fonts.

-

-	See the discussion at

-	http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0

-

-	* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header

-	tags for Keyboard.dfont and LastResort.dfont.

-	* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource

-	starts with TTAG_0xA5kbd or TTAG_0xA5lst.

-	* src/truetype/ttobjs.c (tt_face_init): Accept the face with the

-	format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

-

-2017-09-05  Werner Lemberg  <[email protected]>

-

-	Fix multiple calls of `FT_Bitmap_Convert'.

-

-	The documentation of `FT_Bitmap_Convert' says that multiple calls do

-	proper reallocation of the target FT_Bitmap object.  However, this

-	failed for the sequence

-

-	  non-empty bitmap

-	  empty bitmap

-	  non-empty bitmap

-

-	Reason was that `FT_Bitmap_Convert' only reallocated the bitmap

-	buffer if it became too small; it didn't make the buffer smaller.

-	For an empty bitmap following a non-empty one, only the buffer

-	dimension got set to zero, without deallocation.  If the next call

-	was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was

-	triggered.

-

-	* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target

-	buffer to the correct size.

-

-	* docs/CHANGES: Document it.

-

-2017-09-05  Werner Lemberg  <[email protected]>

-

-	[bdf] Fix size and resolution handling.

-

-	* src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if

-	`POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are

-	missing.

-

-	* docs/CHANGES: Document it.

-

-2017-08-25  Alexei Podtelezhnikov  <[email protected]>

-

-	Swap `ALLOC_MULT' arguments (#51833).

-

-	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated.

-	* src/winfonts/winfnt.c (FNT_Load_Glyph): Updated.

-	* src/raster/ftrend1.c (ft_raster1_render): Updated.

-

-2017-08-23  Werner Lemberg  <[email protected]>

-

-	[sfnt] Fix clang compilation (#51788).

-

-	* src/sfnt/pngshim.c (premultiply_data): Use vectors instead of

-	scalars.

-	(vector_shuffle): New macro to take care of a different built-in

-	function name on clang.

-

-2017-08-22  Werner Lemberg  <[email protected]>

-

-	[base] Don't zero out allocated memory twice (#51816).

-

-	Patch applied from bug report.

-

-	* src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to

-	avoid unnecessary overhead.

-

-2017-08-22  Werner Lemberg  <[email protected]>

-

-	[truetype] Integer overflow.

-

-	Changes triggered by

-

-	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107

-

-	* src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use

-	NEG_LONG.

-

-2017-08-17  Alexei Podtelezhnikov  <[email protected]>

-

-	[sfnt] Avoid synthetic unicode for symbol fonts with PUA.

-

-	Reported as

-

-	  https://bugs.chromium.org/p/chromium/issues/detail?id=754574

-

-	* src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL.

-

-2017-08-16  Werner Lemberg  <[email protected]>

-

-	* src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings.

-

-2017-08-15  Behdad Esfahbod  <[email protected]>

-

-	[sfnt] Speed up PNG image loading.

-

-	This reduces the overhead of `premultiply_data' by 60%.

-

-	* src/sfnt/pngshim.c (premultiply_data): Provide code which uses

-	gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a

-	time.

-

-2017-08-11  Werner Lemberg  <[email protected]>

-

-	[sfnt, truetype] Improve handling of missing sbits.

-

-	Requested by Behdad.

-

-	Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain

-	entries in the bitmap strike(s) for empty glyphs.  Instead, they

-	rely that a space glyph gets created from the font's metrics data.

-	This commit makes FreeType behave accordingly.

-

-	* include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error

-	code.

-

-	* src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes

-	to make a distinction between a missing bitmap in a composite and a

-	simple missing bitmap.

-

-	* src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a

-	bitmap-only font), synthesize an empty bitmap glyph if metrics are

-	available.

-

-2017-08-10  Werner Lemberg  <[email protected]>

-

-	[base] Minor API improvement for default variation axis setting.

-

-	* src/base/ftmm.c (FT_Set_MM_Design_Coordinates,

-	FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates,

-	FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0.

-

-	* docs/CHANGES: Updated.

-

-2017-08-08  Werner Lemberg  <[email protected]>

-

-	[psnames] Really fix issue #49949.

-

-	We now use a separate preprocessor macro to handle both definition

-	and declaration of the glyph name arrays.

-

-	* src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro.

-

-	* src/tools/glnames.py (StringTable::dump,

-	StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'.

-	(dump_encoding): Ditto.

-	(main): Use `wb' mode for writing the output file, which works on

-	Windows also.

-

-	* src/psnames/pstables.h: Regenerated.

-

-2017-08-08  Alexei Podtelezhnikov  <[email protected]>

-

-	[smooth] Harmony LCD rendering.

-

-	This is a new technology for LCD-optimized rendering. It capitalizes

-	on the fact that each color channel grid is shifted by a third of a

-	pixel.  Therefore it is logical to render 3 separate monochrome

-	bitmaps shifting the outline by 1/3 pixel, and then combine them.

-	Importantly, the resulting output does not require additional LCD

-	filtering.

-

-	* src/smooth/ftsmooth.c (ft_smooth_render_generic)

-	[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized

-	rendering.

-

-	* include/freetype/ftlcdfil.h, include/freetype/freetype.h,

-	include/freetype/config/ftoption.h, devel/ftoption.h: Updated

-	documentation.

-

-2017-08-08  Alexei Podtelezhnikov  <[email protected]>

-

-	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up.

-

-2017-08-08  Alexei Podtelezhnikov  <[email protected]>

-

-	* src/sfnt/ttpost.c (format): Use otspec-compliant versions.

-

-2017-08-05  Werner Lemberg  <[email protected]>

-

-	[truetype] Integer overflow.

-

-	Reported as

-

-	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2868

-

-	* src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG.

-

-2017-08-05  Werner Lemberg  <[email protected]>

-

-	[base, truetype] New function `FT_Get_Var_Axis_Flags'.

-

-	The reserved `flags' field got a value in OpenType version 1.8.2;

-	unfortunately, the public `FT_Var_Axis' structure misses the

-	corresponding element.  Since we can't add a new field, we add an

-	access function.

-

-	* src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function.

-

-	* include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro.

-	Updated.

-

-	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory

-	of `mmvar' to hold axis flags.

-	Fill the axis flags array.

-

-	* docs/CHANGES: Updated.

-

-2017-08-03  Nikolaus Waxweiler  <[email protected]>

-

-	[truetype] Fix metrics of B/W hinting in v40 mode.

-

-	Phantom points are now saved outside v40 backwards compatibility

-	mode.  This fixes the jumping glyphs when switching between v35 and

-	v40 monochrome mode.

-

-	* src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic.

-

-2017-08-03  Nikolaus Waxweiler  <[email protected]>

-

-	[truetype] Do not set any ClearType flags in v40 monochrome mode.

-

-	This fixes weird behavior of instructions that resulted in rendering

-	differences between v35 and v40 in monochrome mode, e.g., in

-	`timesbi.ttf'.

-

-	* src/truetype/ttinterp.c (Ins_GETINFO)

-	[TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check

-	`subpixel_hinting_lean'.

-

-2017-08-01  Werner Lemberg  <[email protected]>

-

-	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.

-

-2017-08-01  Behdad Esfahbod  <[email protected]>

-

-	[truetype] Fix loading of named instances.

-

-	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position

-	while loading the `avar' table.

-

-2017-08-01  Werner Lemberg  <[email protected]>

-

-	[sfnt, truetype] Minor adjustments for OpenType 1.8.2.

-

-	* src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now

-	(tighter) limits.

-

-	* src/truetype/ttgload.c (load_truetype_glyph): The new OpenType

-	version explicitly allows all negative values for the number of

-	contours if we have a composite glyph (this is for better backwards

-	compatibility I guess), but it still recommends value -1.

-

-2017-07-26  Werner Lemberg  <[email protected]>

-

-	Handle some integer overflow run-time errors (#46149, #48979).

-

-	This commit (mainly for 32bit CPUs) is the first of a series of

-	similar commits to handle known integer overflows.  Basically, all

-	of them are harmless, since they affect rendering of glyphs only,

-	not posing security threats.  It is expected that fuzzying will show

-	up more overflows, to be fixed in due course.

-

-	The idea is to mark places where overflows can occur, using macros

-	that simply cast to unsigned integers, because overflow arithmetic

-	is well defined in this case.  Doing so suppresses run-time errors

-	of sanitizers without adding computational overhead.

-

-	* include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT,

-	[cff] s/cf2_floatToFixed/cf2_doubleToFixed/.

-	This moves warping option from LIGHT to NORMAL mode.  This makes LIGHT

-	truly void of hinting in x-direction, with left side bearing never

-	changed and right side bearing only altered by advance rounding.

-	Therefore, LIGHT is now ready to return fractional advance.  As a

-	NORMAL option, warping substitutes normal hinting.

-	[truetype] Make `IUP' gvar deltas do the same as Apple (#50832).

-

-	When points are not touched by gvar interpolation deltas, FreeType

-	gave a slightly different result than Apple's CoreText.

-

-	The OpenType working group will update the specification to document

-	the following behaviour: If the two points with deltas to the `left'

-	and `right' of the untouched point have the same coordinate, then

-	the inferred delta for the untouched point should be zero.

-	* src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new

-	behaviour.

-

-	* src/truetype/ttobjs.h (TT_SizeRec): Add field `hinted_metrics' to

-2017-04-22  Werner Lemberg  <[email protected]>

-

-	Add new `slight' auto-hinting mode.

-

-	This mode uses fractional advance widths and doesn't scale glyphs

-	horizontally, only applying vertical scaling and hinting.

-

-	At the same time, the behaviour of the `light' auto-hinter gets

-	restored for backward compatibility: Both vertical and horizontal

-	scaling is again based on rounded metrics values (this was changed

-	in a commit from 2017-03-30 as a side effect).  To be more precise,

-	the behaviour is restored for TrueType fonts only; for other font

-	formats like Type 1, this is a new feature of the `light' hinting

-	mode.

-

-	* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.

-	(FT_RENDER_MODE_SLIGHT): New render mode.

-

-	* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add

-	`autohint_mode' and `autohint_metrics' fields.

-

-	* src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c

-	(af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init):

-	Updated.

-

-	* src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use

-	`autohint_metrics'.

-	(af_loader_load_glyph): s/internal/slot_internal/.

-	Initialize `autohint_metrics' and `autohint_mode' depending on

-	current auto-hint mode.

-	Use `autohint_metrics'.

-	Updated.

-

-	* src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated.

-

-	* src/base/ftobjs.c (FT_Load_Glyph): Updated.

-	(FT_New_Size): Allocate `internal' object.

-	structure with a single field `module_data'.

-

-	* src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of

-	[autofit] Prevent overlapping blue zones.

-

-	Problem reported as

-

-	  https://github.com/google/fonts/issues/632

-

-	The font in question (Nunito) has values 705 and 713 for the

-	reference and overshoot values, respectively, of the first blue

-	zone.  Blue zone 2, however, has value 710 for both the reference

-	and overshoot.  At 12ppem, reference and overshoot of blue zone 0

-	becomes 8px, while blue zone 2 becomes 9px.

-

-	A peculiarity of this font is that the tops of isolated vertical

-	stems like `N' have a slight overshoot also.  The auto-hinter tries

-	to find the nearest blue zone using the *original* coordinates.  For

-	vertical stems, this is value 713.  For normal horizontal tops like

-	in character `E', this is value 710.  Since value 713 is mapped to

-	8px but value 710 to 9px, `N' and similar characters are one pixel

-	higher than `E', which looks very bad.

-

-	This commit sanitizes blue zones to avoid such a behaviour.

-

-	* src/autofit/aflatin.c (af_latin_sort_blue): New function.

-	(af_latin_metrics_init_blues): Sort blue values and remove overlaps.

-	[autofit] Use better blue zone characters for lowercase latin.

-

-	The number of lowercase characters for computing the top flat blue

-	zone value was too small (in most cases only `x' and `z').  If one

-	of the two characters has a large serif, say, it can happen that

-	FreeType must select between two different values, having a 50%

-

-	Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).

-

-	CMake will no longer look for a C++ compiler.

-

-	Library and .so version now match the Autotools build.

-

-	Comments in the build file and informational messages now use platform

-	agnostic example commands.

-	removed. Source packages generated with CPack don't contain Autotools

-	files and aren't used by the maintainers anyway.

-

-	On Windows, src/base/ftver.rc is compiled to decorate the library with

-	version and copyright information.

-

-	A pkg-config file is now generated and installed.

-	[psaux] Fix Type 1 glyphs with too many stem hints.

-

-	According to the CFF specification, charstrings can have up to 96 stem

-	[psaux] Fix CFF advance widths. (#52466)

-

-	Glyph advance widths were being written to the new `PS_Decoder' but not

-	Use Adobe hinting engine for `light' hinting of both CFF and Type 1.

-

-	Since Ewald Hew factored the Adobe hinting engine out of the CFF

-	driver code, we can now use it on Type 1 (and CID) font formats, as

-	both have the same hinting philosophy.

-

-	This change activates the Adobe hinter when in LIGHT mode, and

-	therefore always unless explicitly asking for the auto-hinter.  This

-	makes LIGHT behavior consistent with CFF fonts.  As of this commit,

-	the hinting engine table looks as follows.

-

-	             LIGHT  NORMAL

-	  -------------------------

-	   TrueType  Auto   v40

-

-	The interpreter in Type 1 mode rewinds the charstring after collecting

-	all hints for building the initial hintmap (commit d52dd7f). However,

-	some charstrings use `endchar' in a final subroutine call, rewinding to

-	the start of that subroutine, and only a small section of the actual

-	rendering memory pool.  Now we bisect the bands vertically so that

-

-	[psaux] Fix Type 1 hinting.

-

-	Type 1 hinting breaks sometimes when mid-charstring hints should

-	have been in the initial hintmap.  This fix adds a preprocessing

-	pass that reads all hints and builds the correct initial hintmap

-

-	[psaux] Change subfont synthesis for CID fonts.

-	have this in different places.

-

-	* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to

-	`FT_Face' so that CID is also accepted.

-

-	* src/psaux/psintrp.c (cf2_interpT2CharString)

-	<cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1,

-	to ensure `div' and `callsubr' get values they can use.

-

-2017-09-25  Ewald Hew  <[email protected]>

-

-	[psaux] Extend Adobe interpreter (hints).

-

-	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,

-

-	[psaux] Add missing objects (2/2).

-

-

-	[cff] Fix family name logic of pure CFF fontdata (#52056).

-

-	1. If `FamilyName' is present in the CFF font, use this for

-	   FT_Face's `family_name'.

-	2. Otherwise, use the face name and chop off any subset prefix.

-	3. If at this point FT_Face's `family_name' is set, use this

-	   together with the full name to determine the style.

-	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.

-	5. If we don't have a valid style, use "Regular".

-

-	Previously, FT_Face's `family_name' entry for pure CFF fontdata

-	nearly always was the fontname itself, instead of the `FamilyName'

-	entry in the CFF font (assuming there is one).

-

-	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

-

-2017-09-18  Alexei Podtelezhnikov  <[email protected]>

-

+

+2002-01-29  David Turner  <[email protected]>

+

+	* configure: Fixed the script.  It previously didn't accept more

+	than one argument correctly.  For example, when typing:

+

+	  ./configure --disable-shared --disable-nls

+

+	the `--disable-nls' was incorrectly sent to the `make' program.

+	* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the

+	library when dealing with certain weird fonts like `Stalingrad', in

+	`sadn.pfb' (this font has no full font name entry).

+

+	* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):

+	New function to check the consistency of outline data.

+

+	* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to

+	ensure that loaded glyphs are valid.  This allows certain fonts like

+	`tt1095m_.ttf' to be loaded even though it appears they contain

+	really funky glyphs.

+

+	There still is a bug there, though.

+

+	* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.

+

+2001-12-30  David Turner  <[email protected]>

+

+	* src/autohint/ahhint.c (ah_hinter_load): Fix advance width

+	computation of auto-hinted glyphs.  This noticeably improves the

+	spacing of letters in KDE and Gnome.

+

+2001-12-25  Antoine Leca  <[email protected]>

+

+	* builds/dos/detect.mk: Correcting the order for Borland compilers:

+	16-bit bcc was never selected, always overridden by 32-bit bcc32.

+

+2001-12-22  Francesco Zappa Nardelli  <[email protected]>

+

+	* src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'

+	and fix incorrect computation of `available_sizes'.

+

+2001-12-22  David Turner  <[email protected]>

+

+	* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an

+	incorrect glyph advance in the case of mono-width fonts (like

+	Courier, Andale Mono, and others).

+

+2001-12-22  Detlef Würkner  <[email protected]>

+

+	* builds/amiga/*: Adaptations to latest changes.

+	Support added for MorphOS.

+

+2001-12-22  Werner Lemberg  <[email protected]>

+

+	* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.

+	(ps_mask_table_merge, ps_hints_open, ps_hints_stem,

+	ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix

+	FT_ERROR messages.

+	* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as

+	`trace_pshalgo1'.

+	* src/pshinter/pshalgo2.c (FT_COMPONENT): Define as

+	`trace_pshalgo2'.

+	* include/freetype/internal/ftdebug.h (FT_Trace): Updated.

+

+	* docs/modules.txt: New file.

+

+2001-12-21  David Turner  <[email protected]>

+

+	* src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):

+	Ignore invalid `hintmask' and `cntrmask' operators (instead of

+	returning an error).  Glyph 2028 of the CFF font `MSung-Light-Acro'

+	couldn't be rendered otherwise (it seems its charstring is buggy,

+	though this requires more analysis).

+	(FT_COMPONENT): Define.

+

+	* src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c

+	(T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a

+	bug where the X and Y axis where inverted in the postscript hinter.

+	This caused problem when displaying on non-square surfaces.

+

+	* src/pshinter/pshalgo2.c: s/vertical/dimension/.

+

+	* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating

+	point constant with a fixed-float equivalent.  For some reasons not

+	all compilers are capable of directly computing a floating pointer

+	constant casted to FT_Fixed, and will link a math library instead.

+

+2001-12-20  Werner Lemberg  <[email protected]>

+

+	* src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix

+	tracing strings.

+

+	* src/pshinter/pshrec.c (t2_hint_stems): Fixed.

+

+	* src/base/ftobjs.c (FT_Done_Library): Fixed a stupid bug that

+

+	* src/type1/t1gload.c (T1_Load_Glyph): Enable font matrix

+	transformation of hinted glyphs.

+

+	* src/cid/cidload.c (cid_read_subrs): Fix error condition.

+

+	* src/cid/cidobjs.c (CID_Face_Done): Fixed a memory leak; the subrs

+	routines were never released when CID faces were destroyed.

+

+	* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated

+	to move the definition of encoding tables back within `cffload.c'

+	instead of making them part of a shared header (causing problems in

+	`multi' builds).  This reverts change 2001-08-08.

+

+	* docs/CHANGES: Updated for 2.0.6 release.

+	* docs/TODO: Added `stem3 and counter hints support' to the TODO

+	list for the Postscript hinter.

+	* docs/BUGS: Closed the AUTOHINT-NO-SBITS bug.

+

+2001-12-19  David Turner  <[email protected]>

+

+	* include/freetype/cache/ftcache.h: Added comments to indicate that

+	some of the exported functions should only be used by applications

+	that need to implement custom cache types.

+

+	* src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug

+	that prevented composites from loading correctly, due to missing

+	parentheses around macro parameters.

+

+	* src/sfnt/sfobjs.c (SFNT_Load_Face): Make the `post' and `name'

+	tables optional to load PCL fonts properly.

+

+	* src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c

+	(FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY):

+	`Fixed' the bug that prevented embedded bitmaps to be loaded when

+	the auto-hinter is used.  This actually is a hack but will be enough

+	until the internal re-design scheduled for FreeType 2.1.

+

+	* src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline

+	shifting bug in the monochrome renderer.

+

+	* README: Updated version numbers to 2.0.6.

+2001-12-14  Werner Lemberg  <[email protected]>

+

+	* builds/mac/README: Updated.

+

+2001-12-14  Scott Long  <[email protected]>

+

+	* src/truetype/ttgload.c (load_truetype_glyph): Fixing crash when

+	(T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph),

+	src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to

+	all font drivers (the advance width was never hinted when it

+	should).

+

+	* include/freetype/freetype.h (FREETYPE_PATCH): New macro.

+	* src/base/ftdbgmem.c (debug_mem_dummy) [!FT_DEBUG_MEMORY]: Don't

+	use `extern' keyword.

+

+2001-12-12  David Turner  <[email protected]>

+

+	* src/pshinter/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem

+	psh_globals_new): Adding correct BlueScale/BlueShift support, plus

+	family blues processing.

+	* src/pshinter/pshglob.h (PSH_BluesRec): Updated.

+

+	Started adding support for the Postscript hinter in the CFF module.

+

+	* src/cff/cffgload.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.

+	* src/cff/cffgload.h: Updated.

+

+2001-12-12  Werner Lemberg  <[email protected]>

+2001-12-11  Werner Lemberg  <[email protected]>

+

+	* src/sfnt/ttload.c (TT_Load_Generic_Header): Typos.

+

+2001-12-11  David Turner  <[email protected]>

+

+	* builds/unix/freetype-config.in: Modified the script to prevent

+	passing `-L/usr/lib' to gcc.

+

+	* docs/FTL.TXT: Simple fix (change `LICENSE.TXT' to `FTL.TXT').

+

+	* builds/unix/freetype2.m4: New file for checking configure paths.

+	We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I

+	didn't modify builds/unix/install.mk yet.

+

+	* INSTALL: Updated the instructions to build shared libraries with

+	Jam.  They were simply wrong.

+

+	* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused

+	slightly improper results for `FT_Cos' and `FT_Sin' (example:

+	FT_Sin(0) == -1!).

+

+2001-12-11  Detlef Würkner  <[email protected]>

+

+	* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):

+

+2001-12-06  Leonard Rosenthol  <[email protected]>

+

+	Added support for reading .dfont files on Mac OS X.  Also added a

+	new routine which looks up a given font by name in the Mac OS and

+	returns the disk file where it resides.

+

+	* src/base/ftmac.c: Include <Files.h> and <TextUtils.h>.

+	(is_dfont): New auxiliary function.

+	(FT_New_Face_From_dfont): New function.

+	* include/freetype/ftmac.h: Updated.

+

+2001-12-06  David Turner  <[email protected]>

+

+	* src/cache/Jamfile, src/cache/rules.mk: Updated.

+

+2001-12-06  Werner Lemberg  <[email protected]>

+

+	* INSTALL: Small update.

+

+2001-12-05  David Turner  <[email protected]>

+

+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Re-ordered code for

+	debugging purposes.

+	Comment out use of `origin'.

+

+	* src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug

+	where outline shifting wasn't correctly undone after bitmap

+	rasterization.  This created problems with certain glyphs (like '"'

+	of certain fonts) and the cache system.

+

+	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.

+	* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.

+	(ps2_hints_apply): Small fix.

+

+2001-12-05  David Turner  <[email protected]>

+

+	* src/pshinter/pshalgo2.c (psh2_hint_table_init),

+	src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler

+	warnings.

+

+	* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:

+	Yet another massive rewrite of the caching sub-system in order to

+	both increase performance and allow simpler cache sub-classing.  As

+	an example, the code for the image and sbit caches is now much

+	simpler.

+

+	I still need to update the documentation in

+	www/freetype2/docs/cache.html to reflect the new design though.

+

+	* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New

+	macro.

+	(FT_CACHE_INTERNAL_CACHE_H): Updated.

+

+2001-12-05  David Krause  <[email protected]>

+

+	* docs/license.txt: s/X Windows/X Window System/.

+

+2001-12-04  Werner Lemberg  <[email protected]>

+

+	* src/raster/ftraster.c: Fix definition condition of MEM_Set().

+	* src/smooth/ftgrays.c (M_Y): Change value to 192.

+	* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.

+	Remove unused variable.

+	* src/cache/ftcimage.c (ftc_image_node_init,

+	variable.

+	* src/raster/ftraster.c (MEM_Set): Move definition down to avoid

+	compiler warning.

+	* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to

+	avoid compiler warnings.

+	* src/pcf/pcfread.c (tableNames): Use `const'.

+	(pcf_read_TOC): Change counter name to avoid compiler warning.

+	Use `const'.

+	* src/pshinter/pshrec.c (ps_hints_close): Remove redundant

+	declaration.

+	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables

+	to avoid shadowing.

+	* src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.

+	* src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'

+	and `T1_Size_Done()'.

+

+2001-11-20  Antoine Leca  <[email protected]>

+

+	* include/freetype/ttnameid.h: Added some new Microsoft language

+	codes and LCIDs as found in MSDN (Passport SDK).  Also added

+	comments about the meaning of bit 57 of the `OS/2' table

+	(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is

+	a character beyond 0xFFFF in this font'.  Thanks to Detlef Würkner

+	<[email protected]> for noticing this.

+

+2001-11-20  David Turner  <[email protected]>

+

+	* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting

+	routine that created nasty alignment artefacts.

+

+	* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.

+

+	* src/smooth/ftgrays.c: De-activated experimental gamma support.

+	Apparently, `optimal' gamma tables depend on the monitor type,

+	resolution and general karma, so it's better to compute them outside

+	of the rasterizer itself.

+	(gray_convert_glyph): Use `volatile' keyword.

+

+2001-10-29  David Turner  <[email protected]>

+

+	Adding experimental `gamma' support.  This produces smoother glyphs

+	at small sizes for very little cost.

+

+	* src/smooth/ftgrays.c (grays_init_gamma): New function.

+	(gray_raster_new): Use it.

+

+	Various fixes to the auto-hinter.  They merely improve the output of

+	sans-serif fonts.  Note that there are still problems with serifed

+	fonts and composites (accented characters).

+

+	* src/autohint/ahglyph.c (ah_outline_load,

+	ah_outline_link_segments): Implement it.

+	Fix typos.

+	(ah_outline_save, ah_outline_compute_segments): Fix typos.

+	* src/autohint/ahhint.c (ah_align_serif_edge): New argument

+	`vertical'.  Implement improvement.

+	(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.

+	Fix typos.

+	(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix

+	typos.

+	(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.

+	* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.

+	* src/autohint/ahtypes.h: Ditto.

+	(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'

+	(making them global as `ah_debug_disable_horz' and

+	`ah_debug_disable_vert').

+	Fix typos.

+

+	* tests/gview.c: Updated the debugging glyph viewer to show the

+	hints generated by the `autohint' module.

+

+2001-10-27  David Turner  <[email protected]>

+

+	* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that

+	considerably lowered the performance of the abstract chunk cache.

+

+2001-10-26  David Turner  <[email protected]>

+

+	* include/freetype/ftcache.h, include/freetype/cache/*.h,

+	src/cache/*.c: Major re-design of the cache sub-system to provide

+	better performance as well as an `Acquire'/`Release' API.  Seems to

+	work well here, but probably needs a bit more testing.

+

+2001-10-26  Leonard Rosenthol  <[email protected]>

+

+	* builds/mac/README: Updated to reflect my taking over the project

+	and that is now being actively maintained.

+

+	* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller

+	<[email protected]> to support loading a face other than the

+	first from a FOND resource.

+	(FT_New_Face_From_FOND): Updated.

+

+2001-10-25  Leonard Rosenthol  <[email protected]>

+

+	* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac

+	OS for latest version (7) of CWPro and for recent changes to the FT

+	source tree.

+

+2001-10-25  David Turner  <[email protected]>

+

+	* include/freetype/config/ftoption.h: Updated comments to explain

+	precisely how to use project-specific macro definitions without

+	modifying this file manually.

+

+	(FT_CONFIG_FORCE_INT64): Define.

+

+	(FT_DEBUG_MEMORY): New macro.

+

+2001-10-24  Tom Kacvinsky  <[email protected]>

+

+	* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.

+

+2001-10-23  David Turner  <[email protected]>

+

+	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:

+	Improvements to the memory debugger to report more information in

+	case of errors.  Also, some allocations that occurred through REALLOC

+	couldn't be previously caught correctly.

+

+	* src/autohint/ahglyph.c (ah_outline_compute_segments,

+	ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),

+	src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced

+	liberal uses of memset() by the MEM_Set() macro.

+

+2001-10-23  David Turner  <[email protected]>

+

+	* src/raster/ftraster.c (Update): Removed to be inlined in ...

+	(Sort): Updated.

+

+2001-10-22  David Turner  <[email protected]>

+

+	* builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory),

+	builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),

+	builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),

+	src/base/ftdbgmem.c: Updated the memory debugger and

+	platform-specific implementations of `ftsystem' in order to be able

+	to debug memory allocations on Unix, VMS and Amiga too!

+

+	* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed

+	some bogus warnings.

+

+	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:

+	Modified the debugging memory manager to report the location (source

+	file name + line number) where leaked memory blocks are allocated in

+	the source file.

+

+	* src/base/ftdbgmem.c: New debugging memory manager.  You must

+	define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it.  It

+	will record every memory block allocated and report simple errors

+	like memory leaks and double deletes.

+

+	* src/base/Jamfile: Include ftdbgmem.

+	* src/base/rules.mk: Ditto.

+	* src/base/ftbase.c: Include ftdbgmem.c.

+

+	* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY

+	macro definition.

+

+	* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the

+	base component to use the debugging memory manager when the macro

+	FT_DEBUG_MEMORY is defined.

+

+2001-10-21  Tom Kacvinsky  <[email protected]>

+

+	* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if

+	we are working with a CID keyed CFF font.  Otherwise, a variable

+	that was never allocated memory might freed.  This is a correction

+	to the previous patch for freeing subfonts.

+

+2001-10-21  Tom Kacvinsky  <[email protected]>

+

+	* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to

+	avoid a memory leak.

+2001-10-21  David Turner  <[email protected]>

+

+	* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,

+	src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes

+	(in multi-object compilation mode, mainly).

+

+2001-10-20  Tom Kacvinsky  <[email protected]>

+

+	* src/type1/t1load.c (parse_encoding): Add a test to make sure

+	that custom encodings (i.e., neither StandardEncoding nor

+	ExpertEncoding) are not loaded twice when the Type 1 font is

+	synthetic.

+

+	* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test

+	for when loading synthetic fonts to make sure that the font name

+	and subroutines are not loaded twice.  This is to remove a memory

+	leak that occurred because the original memory blocks for these

+	objects were not deallocated when the objects were parsed the

+	second time.

+

+2001-10-19  David Turner  <[email protected]>

+

+	* src/smooth/ftgrays.c, src/pshinter/pshglob.h,

+

+2001-10-18  David Turner  <[email protected]>

+

+	* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the

+	`glnames.py' script used to generate the `pstables.h' header file.

+	The old one contained a serious bug that made FreeType return

+	incorrect glyph names for certain glyphs.

+

+	* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of

+	pixel size from character size to use rounding.  This is an

+	experiment to see whether this gives values similar to Windows for

+	scaled ascent/descent/etc.

+

+	* src/base/ftcalc.c (FT_Div64by32): Changed the implementation

+	slightly since the original code was mis-compiled on Mac machines

+	using the MPW C compiler.

+

+	* src/base/ftobjs.c (FT_Realloc): When a memory block was grown

+	through FT_Realloc(), the new bytes were not set to 0, which created

+	some strange bugs in the PostScript hinter.

+	(destroy_face): Don't deallocate unconditionally.

+

+	* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):

+	Adding support to new PostScript hinter.

+	src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,

+	src/type1/t1objs.h: Updates to use the new PostScript hinter.

+

+	* tests/Jamfile, tests/gview.c: Adding a new glyph hinting

+	viewer/debugger to the source tree.  Note that you will _not_ be

+	able to compile it since it depends on an unavailable graphics

+	library named `Nirvana' to render vector images.

+

+2001-10-17  David Turner  <[email protected]>

+	generated a dangling pointer reference.

+

+2001-08-30  Anthony Feik  <[email protected]>

+	some old 64-bit computation routines, as well as many warnings when

+	compiling the library with the `long long' 64-bit integer type.

+

+	* include/freetype/config/ftoption.h: Undefine

+

+	Fixed a bug that returned an invalid linear width for composite

+	TrueType glyphs.

+

+	* include/internal/tttypes.h (TT_Loader_): Two new elements `linear'

+	and `linear_def'.

+	* src/truetype/ttgload.c (load_truetype_glyph,

+	details.

+

+	* include/freetype/internal/cfferrs.h,

+	include/freetype/internal/tterrors.h,

+	include/freetype/internal/t1errors.h: Removed.  Replaced with files

+	* Jamfile: Fixed incorrect HDRMACRO argument.

+

+	* TODO: Removed the cubic arc bbox computation note, since it has been

+	fixed recently.

+	* src/base/ftbbox.c (test_cubic_zero): Renamed to...

+

+2001-04-03  Werner Lemberg  <[email protected]>

+

+2001-02-22  David Turner  <[email protected]>

+

+	* src/base/ftgrays.c (grays_sweep): The function didn't exit

+

+	* src/type1/t1objs.c (T1_Init_Face): Added code to get the

+

+	* src/cff/cffparse.c (cff_parse_font_matrix): Added logic to get

+	the units_per_EM from the FontMatrix.

+

+	(cff_parse_fixed_thousand): New function.  Gets a real number from

+	the CFF font, but multiplies by 1000 (this is to avoid rounding

+	into the high sixteen bits of the 16.16 fixed number.

+

+	* src/cff/cffobjs.c (CFF_Init_Face): Added logic to get the units

+

+	* src/type1/t1load.c (is_alpha): Make `-' a legal alphanumeric

+	character.  This is so that font names with `-' are fully parsed,

+	etc...

+

+2001-02-02  Werner Lemberg  <[email protected]>

+

+	* src/psaux/psobjs.c (shift_elements): Remove if clause (which is

+

+2001-02-01  David Turner  <[email protected]>

+

+	* docs/docmaker.py: Improved the index sorting routine to place

+

+2001-01-30  Antoine Leca  <[email protected]>

+

+	* include/freetype/ttnameid.h: Latest updates to Microsoft language

+	units_per_EM from the font matrix.

+

+	(parse_dict): Deleted test to see whether the FontInfo keyword has

+	been seen.  Deletion of this test allows fonts without FontInfo

+	dictionaries to be parsed by the Type 1 driver.

+

+	(T1_Open_Face): Deleted empty subroutines array test to make sure

+	fonts with no subroutines still are parsed.

+

+2001-01-17  Francesco Zappa Nardelli  <[email protected]>

+

+	t2types.h and made this the canonical `types' header for the CFF

+	driver.

+

+	* include/freetype/internal/t2types.h: This file was merged with

+	cfftypes.h and is no longer necessary.

+

+	* include/freetype/internal/t2errors.h: Renamed to cfferrs.h.

+

+	* src/cff/cffobjs.c, src/cff/cffobjs.h, src/cff/cffparse.c,

+

+	* include/freetype/internal/t2types.h,

+	include/freetype/internal/cfftypes.h: Changed the structures for

+	CFF_Charset and CFF_Encoding for the new implementations of the

+	charset and encoding parsers in the CFF driver.

+

+	* src/cff/t2gload.c (t2_lookup_glyph_by_stdcharcode,

+	t2_operator_seac): Added these functions for use in implementing the

+	    cff_expert_charset

+	    cff_expertsubset_charset

+	    cff_standard_encoding

+

+2000-12-24  Tom Kacvinsky  <[email protected]>

+

+	* src/cff/t2gload.c (T2_Load_Glyph): Added code so that the font

+	transform is applied.

+

+	* src/cff/cffparse.c (cff_parse_font_matrix): Added code so that

+

+2000-12-22  Tom Kacvinsky  <[email protected]>

+

+	* src/autohint/ahhint.c (ah_hinter_load_glyph):

+

+2000-12-21  David Turner  <[email protected]>

+

+	* src/cid/cidafm.c, src/cid/cidafm.h: removed un-needed files,

+	we'll work on supporting CID AFM files later I guess :-)

+

+2000-12-21  Tom Kacvinsky  <[email protected]>

+

+	* src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):

+	Changed so that fonts with a non-standard FontMatrix render

+	correctly.  Previously, the first glyph rendered from such a

+	font did not have the transformation matrix applied.

+

+2000-12-17  Werner Lemberg  <[email protected]>

+

+	* *.mk: Added lots of `.PHONY' targets.

+

+2000-12-17  Karsten Fleischer  <[email protected]>

+

+	* *.mk: Implemented `platform' target to disable auto-detection.

+

+2000-12-14  Werner Lemberg  <[email protected]>

+

+	* docs/design/modules.html: Removed.  Covered by design-*.html.

+

+	* INSTALL: Added info about makepp.

+

+2000-12-14  David Turner  <[email protected]>

+

+	Added support for clipped direct rendering in the smooth renderer.

+	This should not break binary compatibility of existing applications.

+

+	* include/freetype/fttypes.h, include/freetype/ftimage.h: Move

+	definition of the FT_BBox structure from the former to the latter.

+	* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to

+	FT_Raster_Flag enumeration.

+	Add `clip_box' element to FT_Raster_Params structure.

+	* src/smooth/ftgrays.c (grays_convert_glyph): Implement it.

+

+	* INSTALL: Updated installation instructions on Win32, listing the

+	new `make setup list' target used to list supported

+

+	* src/raster/ftraster.c (ft_black_render): Test for unsupported

+	direct rendering before testing arguments.

+

+2000-12-13  David Turner  <[email protected]>

+

+	* include/freetype/config/ft2build.h,

+	include/freetype/internal/internal.h: Fixed header inclusion macros

+	to use direct definitions.  This is the only way to do these things

+	in a portable way :-(  The rest of the code should follow shortly

+	though everything compiles now.

+

+	* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.

+

+	* builds/win32/detect.mk: Added support for the Intel C/C++

+	compiler, as well as _preliminary_ (read: doesn't work!) support for

+	Watcom.  Also added a new setup target.  Type `make setup list' for

+	a list of supported command-line compilers on Win32.

+

+	* src/base/ftdebug.c: Added dummy symbol to avoid empty file if

+	conditionals are off.

+

+2000-12-13  Werner Lemberg  <[email protected]>

+

+	* builds/unix/ftsystem.c: Fixed typos.  Fixed inclusion of wrong

+	ftconfig.h file.

+

+2000-12-12  Werner Lemberg  <[email protected]>

+

+	* include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):

+	Removed.  ANSI C doesn't (explicitly) allow macro expansion in

+	arguments using `##'.

+	(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory

+	names directly.  Make them configurable.  Use `##' to strip leading

+	and trailing spaces from arguments.

+

+	* builds/unix/ft2unix.h: Adapted.

+

+	* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,

+	ft_close_stream): Use FT_CALLBACK_DEF.

+

+	* builds/unix/ftsystem.c: Use new header scheme.

+	(FT_Done_Memory): Use free() from FT_Memory structure.

+

+	* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.

+

+2000-12-11  Werner Lemberg  <[email protected]>

+

+	* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,

+	FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,

+	FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.

+

+2000-12-09  Werner Lemberg  <[email protected]>

+

+	* builds/unix/detect.mk: Remove unused USE_CFLAGS variable.

+

+2000-12-08  Werner Lemberg  <[email protected]>

+

+	* */*.h: Changed body inclusion macro names to start and end with

+	`__' (those which haven't converted yet).  Fixed minor conversion

+	issues.

+

+	* src/winfonts/winfnt.c: Updated to new header inclusion scheme.

+

+	* src/truetype/ttinterp.c: Remove unused CALC_Length() macro.

+

+2000-12-07  David Turner  <[email protected]>

+

+	* */*.[ch]: Changed source files to adhere to the new

+	header inclusion scheme.  Not completely tested but works for now

+	here.

+

+	* src/cff/t2driver.c: Renamed and updated to...

+

+2000-12-06  David Turner  <[email protected]>

+

+	* src/cache/ftlru.c (FT_Lru_Done): Fixed memory leak.

+

+2000-12-06  Werner Lemberg  <[email protected]>

+

+	* builds/module.mk: Replaced `xxx #' with `xxx$(space).

+	* builds/os2/detect.mk, builds/win32/detect.mk: Moved comment to

+	avoid trailing spaces in variable.

+	* builds/freetype.mk: Use $(D) instead of $D to make statement more

+	readable.

+

+	* docs/docmaker.py: Formatting.

+

+2000-12-05  David Turner  <[email protected]>

+

+	* src/psaux/psauxmod.c: Fixed a broken inclusion of component

+	header files (an FT_FLAT_COMPILE test was missing).

+

+	* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused

+	an occasional crash when the function was called (due to a dangling

+	pointer).

+

+	* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:

+	The ANSI `free()' function was called instead of `memory->free()'.

+

+	* docs/docmaker.py: Added section filtering, multi-page generation

+	(index page generation is still missing though).

+

+2000-12-04  David Turner  <[email protected]>

+

+	* builds/unix/install.mk, builds/unix/ft2unix.h: The file `ft2unix.h'

+	is now installed as <ft2build.h> for Unix systems.  Note that we

+	still use the `freetype2/freetype' installation path for now.

+

+	* */*.[ch]: Now using <ft2build.h> as the default build and setup

+	configuration file in all public headers.  Internal source files

+	still need some changes though.

+

+	* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new

+	directory to hold all development options for both the Unix and

+	Win32 developer builds.

+

+	* builds/win32/detect.mk, builds/win32/w32-bccd.mk,

+	builds/win32/w32-dev.mk: Changed the developer build targets to

+	`devel-gcc' and `devel-bcc' in order to be able to develop with the

+	Borland C++ compiler.

+

+2000-12-01  David Turner  <[email protected]>

+

+

+	* Version 2.0.1 released.

+	=========================

+

+

+	* builds/unix/configure.in, builds/unix/configure,

+

+	* CHANGES: Added a summary of changes between 2.0.1 and 2.0.

+

+	* builds/unix/ftconfig.in, builds/cygwin/ftconfig.in: Changes

+	to allow compilation under Unix with the Unix-specific config

+	files.

+

+2000-12-01  Werner Lemberg  <[email protected]>

+

+	* INSTALL: Revised.

+	* builds/compiler/bcc-dev.mk, builds/compiler/visualage.mk,

+	builds/compiler/bcc.mk, builds/win32/w32-bcc.mk,

+	builds/win32/w32-bccd.mk: Revised.

+	* include/freetype/config/ftbuild.h,

+	include/freetype/internal/internal.h: Revised.

+	* include/freetype/ftimage.h: Updated to new header inclusion scheme.

+

+2000-11-30  Werner Lemberg  <[email protected]>

+

+	* builds/toplevel.mk (.PHONY): Adding `distclean'.

+	* builds/unix/detect.mk (.PHONY): Adding `devel', `unix', `lcc',

+	`setup'.

+

+2000-11-30  David Turner  <[email protected]>

+

+	* INSTALL: Slightly updated the quick starter documentation to

+	include IDE compilation, prevent against BSD Make, and specify `make

+	setup' instead of a single `make' for build configuration.

+

+	* include/config/ftbuild.h, include/internal/internal.h: Added new

+	configuration files used to determine the location of all public,

+	configuration, and internal header files for FreeType 2.  Modified

+	all headers under `include/freetype' to reflect this change.  Note

+	that we still need to change the library source files themselves

+	though.

+

+	* builds/compiler/bcc.mk, builds/compiler/bcc-dev.mk,

+	builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk,

+	builds/win32/detect.mk: Added new files to support compilation with

+	the free Borland C++ command-line compiler.  Modified the detection

+	rules to recognize the new `bcc32' target in `make setup bcc32'.

+

+	* src/sfnt/ttcmap.c, src/sfnt/ttpost.c, src/sfnt/ttsbit.c,

+	src/truetype/ttobjs.c, src/truetype/ttgload.c,

+	src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++

+	didn't really like.  Basically, this compiler complains when FT_UInt

+	is compared to FT_UShort (apparently, it promotes `UShort' to `Int'

+	in these cases).

+

+2000-11-30  Tom Kacvinsky  <[email protected]>

+

+	* t2objs.c (T2_Init_Face): Added calculation of `face->height' for

+	pure CFF fonts.

+

+	* t1objs.c (T1_Init_Face): Fixed computation of `face->height'.

+

+2000-11-29  David Turner  <[email protected]>

+

+	* src/base/ftbbox.c (BBox_Conic_Check): Fixed a really stupid

+	bug in the formula used to compute the conic Bézier extrema

+	src/cache/ftcmanag.c (FTC_Manager_Done, FTC_Manager_Reset,

+	FTC_Manager_Lookup_Face, FTC_Manager_Lookup_Size,

+	FTC_Manager_Register_Cache), src/cache/ftcsbits.c

+	(FTC_SBit_Cache_Lookup): Ditto.

+

+	* src/include/freetype/cache/ftcglyph.h (FTC_GlyphNode_Init),

+	src/include/freetype/ftmac.h (FT_New_Face_From_FOND): Use FT_EXPORT.

+

+2000-11-29  Werner Lemberg  <[email protected]>

+	`size->strike_index' only conditionally.

+

+	* src/type1/t1driver.c, src/type1/t1objs.c: Include t1afm.h only

+	conditionally.

+

+	* src/winfonts/winfnt.h: Move all type definitions to...

+	* src/include/freetype/internal/fnttypes.h: New file.

+	* src/winfonts/winfnt.c: Use it.

+

+2000-11-29  ??? ???  <[email protected]>

+

+	* include/freetype/internal/ftdebug.h: Replaced FT_CAT and FT_XCAT

+	with a direct solution (which also satisfies picky compilers).

+

+	Say you have `(Foo*)x' and want to assign, pass, or return it as

+	`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler

+	would warn you that type casting incompatible pointer types breaks

+	strict-aliasing.  The solution is to cast to `(void*)' instead which

+	is the generic pointer type, so the compiler knows that it should

+	make no strict-aliasing assumption on `x'.  But the problem with

+	`(void*)x' is that seems like in C++, unlike C, `void*' is not a

+	generic pointer type and assigning `void*' to `Bar*' without a cast

+	causes an error.  The solution is to cast to `Bar*' too, with

+	`(Bar*)(void*)x' as the result -- this is what the patch does.

+

+	* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),

+	FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),

+

+	* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.

+

+2005-02-25  David Turner  <[email protected]>

+

+	Implement several memory optimizations to drastically reduce the

+	heap usage of FreeType, especially in the case of memory-mapped

+	files.  The idea is to avoid loading and decoding tables in the

+	heap, and instead access the raw data whenever possible (i.e., when

+	it doesn't compromise performance).

+

+	This has several benefits: For example, opening vera.ttf now uses

+	just a small amount of memory (even when the FT_Library footprint is

+	accounted for), until you start loading glyphs.  Even then, you save

+	at least 20KB compared to the non-optimized case.  Performance of

+	various operations, including open and close, has also been

+	dramatically improved.

+

+	More optimizations to come, especially for the auto-hinter.

+	* include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New

+	function type.

+	`hdmx_record_sizes', `kern_table', `kern_table_size,

+	`num_kern_tables', `kern_avail_bits', `kern_order_bits' if

+	FT_OPTIMIZE_MEMORY is set.

+	Don't define `hdmx', `num_kern_pairs', `kern_table_index',

+	Fixed a dangling pointer bug in the cache code that happened in very

+	=========================

+

+

+	* src/truetype/ttgload.c, src/truetype/ttxgvar.c: Removing

+	compiler warnings.

+

+2004-06-23  Werner Lemberg  <[email protected]>

+

+	* include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare

+	FT_QAlloc_Debug and FT_QRealloc_Debug.

+

+	* src/base/ftutil.c (FT_QAlloc): Fix error and debug messages.

+	(FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,

+	FT_QRealloc_Debug): New functions that perform allocation without

+	zero-ing out the corresponding blocks.

+

+	* include/freetype/internal/ftmemory.h (FT_MEM_QALLOC,

+	FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY,

+

+	* include/freetype/config/ftmodule.h: Changed the order of modules,

+	performance of face open/close operations.  For example, putting the

+	TrueType driver first in the list results in a 5x speedup when

+	opening `Vera.ttf'.

+

+	The very problem is that both the PCF and BDF drivers do a lot more

+	than necessary to detect that they cannot handle a font file.

+

+	To test it, change `autohint' to `autofit' in

+	of the order of various MM-specific keywords, the parse_shared_dict

+	routine has been removed -- the PS parser is now capable to skip

+	this data.  It no longer fails on parsing e.g.

+

+	  dup /WeightVector exch def

+

+	Since the token following /WeightVector isn't `[' (starting an

+	array) it is simply ignored.

+

+	* include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a

+	new internal error value.

+

+	* src/type1/t1load.c (parse_blend_axis_types,

+	parse_blend_design_positions, parse_blend_design_map): Return

+	T1_Err_Ignore if no proper array is following the keyword.

+	(parse_weight_vector): Use T1_ToTokenArray, initializing `blend'

+	structure, if necessary.

+	Return T1_Err_Ignore if no proper array is following the keyword.

+	(parse_shared_dict): Removed.

+	(parse_encoding): Set parser->root.error to return T1_Err_Ignore

+	if no result can be obtained.

+	Check for errors before accessing `elements' array.

+	(t1_keywords): Remove /shareddict.

+	(parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore.

+	Set keyword_flag only in case of success.

+	Check error code if skipping an unrecognized token.

+	(T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend

+	if blend commands haven't set up a proper MM font.

+

+	* src/psaux/psobjs.c (ps_parser_load_field_table): Remove special

+	code for synthetic fonts.

+	Return PSaux_Err_Ignore if no proper value has been found.

+	doesn't recognize them properly.

+	(T1_Open_Face): Improve an error message.

+

+2004-02-01  Werner Lemberg  <[email protected]>

+

+	* src/type1/t1load.c (parse_charstrings): Exit immediately if

+

+	* Jamfile: Updating `refdoc' target, and adding `autohint' to the

+	(parse_dict): Skip all /CharStrings arrays but the first.  We need

+	this for non-standard fonts like `Optima' which have different

+	outlines depending on the resolution.  Note that there is no

+	guarantee that we get fitting /Subrs and /CharStrings arrays; this

+	can only be done by a real PS interpreter.

+

+	  *Complete* rewrite of the cache sub-system to `solve' the

+	  following points:

+

+	    - all public APIs have been moved to FT_CACHE_H, everything

+	      under `include/freetype/cache' is only needed by client

+	      applications that want to implement their own caches

+

+	    - a new function named FTC_Manager_RemoveFaceID to deal

+	      with the uninstallation of FaceIDs

+

+	    - the image and sbit cache are now abstract classes, that

+	      can be extended much more easily by client applications

+

+	    - better performance in certain areas.  Further optimizations

+	      to come shortly anyway...

+

+	    - the FTC_CMapCache_Lookup function has changed its signature,

+	      charmaps can now only be retrieved by index

+

+	    - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace

+	      FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in

+	      private header for the moment)

+

+	A new try to synchronize bitmap font access.

+

+	* include/freetype/freetype.h (FT_Bitmap_Size): `height' is now

+	defined to return the baseline-to-baseline distance.  This was

+	already the value returned by the BDF and PCF drivers.

+

+	The `width' field now gives the average width.  I wasn't able to

+	find something better.  It should be taken as informative only.

+

+	New fields `size', `x_ppem', and `y_ppem'.

+2003-06-29  Werner Lemberg  <[email protected]>

+

+	Redesigning the FNT driver to return multiple faces, not multiple

+	strikes.  At least one font (app850.fon from WinME) contains

+	different FNT charmaps for its subfonts.  Consequently, the previous

+	design of having multiple bitmap strikes in a single font face fails

+	since we have only one charmap per face.

+	bitmap width is now ignored.

+	(FNT_Load_Glyph): Updated.

+	Fix glyph index computation.

+	(winfnt_driver_class): Updated.

+

+2003-06-25  Owen Taylor  <[email protected]>

+

+	* src/sfnt/ttload.c (tt_face_load_hdmx): Don't assign

+	Without this fix it isn't possible to access all strikes.

+	Also compute metrics.max_advance to be in sync with other bitmap

+	drivers.

+

+	* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.

+

+2003-06-20  Werner Lemberg  <[email protected]>

+

+	Synchronize computation of height and width for bitmap strikes.  The

+	`width' field in the FT_Bitmap_Size structure is now only useful to

+	enumerate different strikes.  The `max_advance' field of the

+	FT_Size_Metrics structure should be used to get the (maximum) width

+	of a strike.

+

+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for

+	computing `available_sizes->width' but make it always equal to

+	`available_sizes->height'.

+

+	* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for

+

+2003-06-09  Alexis S. L. Carvalho  <[email protected]>

+

+	* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Handle Z_STREAM_END

+	* src/pfr/rules.mk (PFR_DRV_SRC): Add pfrsbit.c.

+	(PFR_DRV_H): Add pfrtypes.h.

+

+2003-06-08  Karl Schultz  <[email protected]>

+

+	* src/pfr/pfrsbit.c (pfr_bitwriter_init): Change type of third

+	argument to FT_Bool.

+

+2003-06-08  Werner Lemberg  <[email protected]>

+

+	Completely revised FreeType's make management.

+

+	. In all makefiles `/' is used as the path separator.  The

+	  conversion to the real path separators is done as late as

+	  possible using $(subst ...).

+

+	. $(HOSTSEP) no longer exists.  Now, $(SEP) gives the path separator

+	  for the operating system, and the new $(COMPILER_SEP) the path

+	  separator for the compiler tools.

+

+	. $(BUILD) has been renamed to $(BUILD_DIR).  In general, all

+	  directory variables end with `_DIR'.  The variants ending in `_'

+	  (like `BASE_' have been removed).

+

+	The following ChangeLog entries only describe changes which are

+	not related to the redesign.

+

+	* builds/beos/beos-def.mk (BUILD_DIR): Fix typo.

+	* builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid

+2003-06-04  Werner Lemberg  <[email protected]>

+

+	* include/freetype/config/ftoption.h: Defining

+	TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING by default is a bad idea

+	since some fonts (e.g. Arial) produce worse results than without

+

+2003-06-04  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttgload.c (load_truetype_glyph)

+	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call

+

+	* include/freetype/config/ftoption.h: Define

+	TT_CONFIG_OPTION_BYTECODE_INTERPRETER,

+

+2003-06-03  Werner Lemberg  <[email protected]>

+2003-06-02  Werner Lemberg  <[email protected]>

+

+2003-04-25:  Graham Asher  <[email protected]>

+

+	Added the optional unpatented hinting system for TrueType.  It

+

+2003-04-25  Werner Lemberg  <[email protected]>

+

+	* src/bdf/bdflib.c (hash_bucket, hash_lookup): Use `const' for first

+	argument.

+	(bdf_get_font_property): Use `const' for third argument.

+	Updated all callers.

+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height

+	similar to the PCF driver.

+	* src/bdf/bdf.h (_hashnode): Use `const' for `key'.

+	Updated.

+

+	* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'

+	is declared twice.  It is perhaps better to modify the zlib source

+	files directly instead of this hack.

+	(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts

+	to make build with g++ successful.

+

+2003-04-24  Manish Singh  <[email protected]>

+

+	* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c

+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Split on `-'

+	also for searching the style name.

+

+2003-04-24  David Turner  <[email protected]>

+

+	* src/pcf/pcfread.c (pcf_load_font): Fixed the computation of

+	face->num_glyphs.  We must increase the value by 1 to respect the

+	convention that glyph index 0 always corresponds to the `missing

+	glyph'.

+

+2003-04-24  Werner Lemberg  <[email protected]>

+

+	* builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@.

+

+2003-04-24  Dieter Baron  <[email protected]>

+

+	* builds/unix/freetype-config.in (cflags): Emit FreeType 2's include

+	installed simultaneously.

+

+2003-04-23  Werner Lemberg  <[email protected]>

+

+	Fixing bugs reported by Nelson Beebe.

+

+	* src/type1/t1gload.c (T1_Load_Glyph): Use `glyph_data_loaded'

+	only for FT_CONFIG_OPTION_INCREMENTAL.

+

+2003-04-23  Akito Hirai  <[email protected]>

+

+	* src/sfnt/ttcmap0.c (tt_cmap4_validate): Provide a weak variant

+	of the glyph ID bounding check if FT_VALIDATE_TIGHT is not active.

+	Without this change, many CJK fonts from Dynalab are rejected.

+

+2003-04-23  Joe Marcus Clarke  <[email protected]>

+

+	* src/base/ftbdf.c (FT_Get_BDF_Property): Check for valid

+	`get_interface'.

+

+2003-04-23  Paul Miller  <[email protected]>

+

+	* src/base/ftmac.c (parse_fond): Fix handling of style names.

+

+2003-04-23  Werner Lemberg  <[email protected]>

+

+	* src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist

+	instead of FT_UInt for `len'.

+

+2003-04-22  Werner Lemberg  <[email protected]>

+

+	* src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]:

+	bug that had nasty consequences when trying to open an `invalid'

+	font on a Mac.

+

+2003-04-09  Mike Fabian  <[email protected]>

+

+	* src/bdf/bdfdrivr.h (BDF_encoding_el), src/pcf/pcf.h

+	(PCF_EncodingRec): Changed FT_Short to FT_UShort in order to be able

+	to access more than 32768 glyphs in fonts.

+

+2003-04-08  David Turner  <[email protected]>

+

+

+	* Version 2.1.4 released.

+	=========================

+

+

+2003-04-03  Martin Muskens  <[email protected]>

+

+	* src/type1/t1load.c (T1_Open_Face): Fixed the code to make it

+	handle special cases where a font only contains a `.notdef' glyph

+	(happens in PDF-embedded fonts).  Otherwise, FT_Panic was called.

+

+2003-03-27  David Turner  <[email protected]>

+

+	* README: Updated.

+

+	* README.UNX: Removed (now replaced by docs/INSTALL.UNX).

+

+	* src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and

+	will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is

+	used.

+	(psh3_dimension_quantize_len): Enabled.

+	(psh3_hint_align): Enable commented code.

+	(psh3_hint_align_light): Commented out.

+

+	* src/base/ftobjs.c (FT_Set_Char_Size): Changed the default

+	computations to include rounding in all cases; this is required to

+	provide accurate kerning data when native TrueType hinting is

+	enabled.

+

+	* src/type1/t1load.c (is_name_char): The Type 1 loader now accepts

+	more general names according to the PostScript specification (the

+	previous one was too restrictive).

+	(parse_font_name, parse_encoding, parse_charstrings, parse_dict):

+	Use `is_name_char'.

+	(parse_subrs): Handle empty arrays.

+

+2003-03-20  David Turner  <[email protected]>

+

+	Serious rewriting of the documentation.

+

+	* docs/BUGS, docs/BUILD: Removed.

+	* docs/DEBUG.TXT: Renamed to...

+	* docs/DEBUG: This.

+	* docs/CUSTOMIZE, docs/TRUETYPE, docs/UPGRADE.UNX: New files.

+	* docs/INSTALL.ANY, docs/INSTALL.UNX, docs/INSTALL.GNU New files,

+	containing platform specific information previously in INSTALL.

+	* docs/readme.vms: Renamed to...

+	* docs/INSTALL.VMS: This.

+

+	* docs/*: Updated.

+

+	Introduced three new functions to deal with glyph bitmaps within

+	FT_GlyphSlot objects:

+

+	  ft_glyphslot_free_bitmap

+	  ft_glyphslot_alloc_bitmap

+	  ft_glyphslot_set_bitmap

+

+	These functions are much more convenient to use than managing the

+	FT_GLYPH_OWN_BITMAP flag manually.

+

+	* include/freetype/internal/ftobjs.h (ft_glyphslot_free_bitmap,

+	ft_glyphslot_alloc_bitmap, ft_glyphslot_set_bitmap): New functions.

+	* src/base/ftobjs.c: Implement them.

+	(ft_glyphslot_done): Use ft_glyphslot_free_bitmap.

+

+	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdriver.c

+	(PCF_Glyph_Load): Remove unused variable `memory'.

+	Use `ft_glyphslot_*' functions.

+	Don't set `FT_GLYPH_OWN_BITMAP'.

+

+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Use

+	`ft_glyphslot_alloc_bitmap'.

+

+	* src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type

+	`FT_GlyphSlot'.

+	Adding argument `depth' to handle recursive calls.

+	Use `ft_glyphslot_alloc_bitmap'.

+	(tt_face_load_sbit_image): Remove unused variable `memory'.

+	Don't handle `FT_GLYPH_OWN_BITMAP'.

+	Update call to Load_SBit_Image.

+

+	* src/type42/t42objs.c (ft_glyphslot_clear): Renamed to...

+	(t42_glyphslot_clear): This.  Updated caller.

+	Call `ft_glyphslot_free_bitmap'.

+

+	* src/winfonts/winfnt.c (FNT_Load_Glyph): Use

+	`ft_glyphslot_set_bitmap'.

+	Don't handle `FT_GLYPH_OWN_BITMAP'.

+

+	* src/cache/ftlru.c (FT_LruList_Lookup): Fixed an invalid assertion

+	check.

+

+	* src/autohint/ahglyph.c (ah_outline_load): Add two scaling

+	arguments.

+	* src/autohint/ahglyph.h: Updated.

+	* src/autohint/ahhint.c (ah_hinter_load): Updated.

+	* src/autohint/ahglobal.c (ah_hinter_compute_widths): Updated.

+

+	* src/cache/ftccache.c (ftc_family_done): Fixed small bug that could

+	crash the cache in rare circumstances (mostly with broken fonts).

+

+2003-03-15  David Turner  <[email protected]>

+

+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding

+	bug.  Actually, it seems that previous versions of FreeType didn't

+	perform TrueType rounding exactly as appropriate.

+

+2003-03-14  David Turner  <[email protected]>

+

+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small

+	TrueType native rendering glitches; they came from a small rounding

+	error.

+

+2003-03-13  David Turner  <[email protected]>

+

+	Added new environment variables to control memory debugging with

+	FreeType.  See the description of `FT2_DEBUG_MEMORY',

+	`FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT.

+

+	* src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count',

+	`bound_total', `alloc_total_max', `bound_count', `alloc_count_max'.

+	(ft_mem_debug_alloc): Handle new variables.

+	(ft_mem_debug_init): s/FT_DEBUG_MEMORY/FT2_DEBUG_MEMORY/.

+	Handle new environment variables.

+	* docs/DEBUG.TXT: Updated.

+

+	Fixed the cache sub-system to correctly deal with out-of-memory

+	conditions.

+

+	* src/cache/ftccache.c (ftc_node_destroy): Comment out generic

+	check.

+	(ftc_cache_lookup): Implement loop.

+	* src/cache/ftccmap.c: Define FT_COMPONENT.

+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Handle

+	FT_Err_Out_Of_Memory.

+	* src/cache/ftlru.c: Include FT_INTERNAL_DEBUG_H.

+	(FT_LruList_Lookup): Implement loop.

+

+	* src/pfr/pfrobjs.c (pfr_face_done): Fix memory leak.

+	(pfr_face_init): Fixing compiler warnings.

+

+	* src/psaux/psobjs.c (reallocate_t1_table): Fixed a bug (memory

+	leak) that only happened when a try to resize an array would end in

+	an out-of-memory condition.

+

+	* src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler

+	warnings / volatile bug.

+

+	* src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation

+	fault that happened in tight memory environments.

+

+2003-02-28  Pixel  <[email protected]>

+

+	* src/gzip/ftgzip.c (ft_gzip_file_done): Fixed memory leak: The ZLib

+	stream was not properly finalized.

+

+2003-02-25  Anthony Fok  <[email protected]>

+

+	* src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H.

+	(ftc_cmap_family_init): The cmap cache now

+	supports UCS-4 charmaps when available in Asian fonts.

+

+	* src/sfnt/ttload.c, src/base/ftobjs.c: Changed `asian' to `Asian'

+	in comments.

+

+2003-02-25  David Turner  <[email protected]>

+

+	* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that

+	caused FreeType to loop endlessly when trying to read certain

+	compressed gzip files.  The following test reveals the bug:

+

+	  touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz

+

+	Several fixes to the PFR font driver:

+

+	- The list of available embedded bitmaps was not correctly set in

+	  the root FT_FaceRec structure describing the face.

+

+	- The glyph loader always tried to load the outlines when

+	  FT_LOAD_SBITS_ONLY was specified.

+

+	- The table loaded now scans for *undocumented* elements of a

+	  physical font's auxiliary data record.  This is necessary to

+	  retrieve the `real' family and style names.

+

+	NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS!

+

+	* src/pfr/pfrload.c (pfr_aux_name_load): New function.

+	(pfr_phy_font_done): Free `family_name' and `style_name' also.

+	Remove unused variables.

+	(pfr_phy_font_load): Extract useful information from the auxiliary

+	bytes.

+

+	* src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL.

+	(pfr_face_init): Provide fallback values for `family_name' and

+	`style_name'.

+	Handle strikes.

+	(pfr_slot_load): Handle FT_LOAD_SBITS_ONLY.

+	* src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent',

+	`descent', `leading', `family_name', and `style_name'.

+

+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug

+	when computing the scale factors for a given character size in

+	points with resolution.

+

+	* devel/ft2build.h, devel/ftoption.h: New files (in a new directory)

+	which are special development versions of include/ft2build.h and

+	include/freetype/config/ftoption.h, respectively.

+

+2003-02-18  David Turner  <[email protected]>

+

+	Fixing the slight distortion problem that occurred due to the latest

+	auto-hinter changes.

+

+	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding.

+

+	* src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'.

+	[!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed.

+

+	* src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'.

+	* src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of

+	`metrics'.

+	[FT_CONFIG_CHESTER_ASCENDER]: Code removed.

+	(Reset_SBit_Size): Fix initialization of `metrics'.

+

+	* src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of

+	`exec->metrics'.

+

+	* src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width

+	`correction' which seemed to provide more trouble than benefits.

+

+2003-02-13  Graham Asher  <[email protected]>

+

+	Changed the incremental loading interface in a way that makes it

+	simpler and allows glyph metrics to be changed (e.g., by adding a

+	constant, as required by CFF fonts) rather than just overridden.

+	This was required to make the GhostScript-to-FreeType bridge work.

+

+	* src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]:

+	Allow metrics to be overridden.

+	* src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]:

+	Ditto.

+

+	* src/truetype/ttgload.c (load_truetype_glyph)

+	[FT_CONFIG_OPTION_INCREMENTAL]: Simplify.

+	(compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block

+	moved down.

+

+	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String)

+	[FT_CONFIG_OPTION_INCREMENTAL]: Updated.

+

+	* include/freetype/ftincrem.h: Updated.

+

+2003-01-31  David Turner  <[email protected]>

+

+	* docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation

+	for the 2.1.4 release.

+

+	* builds/win32/visualc/freetype.dsp,

+	builds/win32/visualc/index.html: Updating the project file for

+	2.1.4.

+

+	* src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c,

+	src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c,

+	src/gzip/infutil.c: Removed old-style (K&R)function definitions.

+	This avoids warnings with Visual C++ at its most pedantic mode.

+

+	* src/pfr/pfrsbit.c: Removed compiler warnings.

+

+	* src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR

+	into an FT_TRACE1 since it caused `ftview' and others to dump too

+	much junk when trying to display a waterfall with a font without a

+	Unicode charmap (e.g.  SYMBOL.TTF).

+

+	Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last

+	patch from David Chester, but with a much simpler (and saner)

+	implementation.

+

+	* src/autohint/ahhint.c (ah_hinter_load_glyph)

+	[FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that

+	the top of non-capital letters is aligned on a pixel boundary

+	whenever possible.

+

+	* src/base/ftobjs.c (FT_Set_Char_Size)

+	[FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently.

+	* src/truetype/ttdriver.c (Set_Char_Sizes)

+	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only

+	if this macro is defined.

+

+	* src/truetype/ttobjs.c (Reset_Outline_Size)

+	[FT_CONFIG_CHESTER_ASCENDER]: Round differently.

+

+	* src/pshinter/pshalgo3.c: Improved the Postscript hinter.  Getting

+	rid of stem snapping seems to work well here (though the stems are

+	still slightly moved to increase contrast).

+	(psh3_dimension_quantize_len): Commented out.

+	(psh3_hint_align_light): New function.

+	(psh3_hint_align): Comment out some code.

+

+	THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES

+	STILL SUCK.

+

+2003-01-22  David Chester  <[email protected]>

+

+	* src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the

+	stem width optimization.

+

+2003-01-22  David Turner  <[email protected]>

+

+	Adding a new API `FT_Get_BDF_Property' to retrieve the BDF

+	properties of a given PCF or BDF font.

+

+	* include/freetype/ftbdf.h (BDF_PropertyType): New enumeration.

+	(BDF_Property, BDF_PropertyRec): New structure.

+	FT_Get_BDF_Property): New function.

+	* include/freetype/internal/bdftypes.h: Include FT_BDF_H.

+	(BDF_GetPropertyFunc): New function pointer.

+

+	* src/base/ftbdf.c (test_font_type): New helper function.

+	(FT_Get_BDF_Charset_ID): Use `test_font_type'.

+	(FT_Get_BDF_Property): New function.

+

+	* src/bdf/bdfdrivr.c: Include FT_BDF_H.

+	(bdf_get_bdf_property, bdf_driver_requester): New functions.

+	(bdf_driver_class): Use `bdf_driver_requester'.

+

+	* src/pcf/pcfdrivr.c: Include FT_BDF_H.

+	(pcf_get_bdf_property, pcf_driver_requester): New functions

+	(pcf_driver_class): Use `pcf_driver_requester'.

+

+	* src/pcf/pcfread.c: Include `pcfread.h'.

+	(pcf_find_property): Decorate it with FT_LOCAL_DEF.

+	* src/pcf/pcfread.h: New file, providing `pcf_find_property'.

+

+	* src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size

+	verification to accept a few broken fonts who pad the size

+	incorrectly (the table should be padded, but its `size' field

+	shouldn't according to the specification).

+

+2003-01-18  Werner Lemberg  <[email protected]>

+

+	* builds/unix/ltmain.sh: Regenerated with `libtoolize --force

+	--copy' from libtool 1.4.3.

+	* include/freetype/freetype.h: Fixed documentation for

+	FT_Size_Metrics.

+

+2003-01-15  James Su  <[email protected]>

+

+	* src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read

+	certain gzip-ed font files (typo: `&&' -> `&').

+

+2003-01-15  Huw D M Davies  <[email protected]>

+

+	Added a Windows .FNT specific API (mostly for Wine).  Also fixed a

+	nasty bug in the header loader which would cause invalid memory

+	overwrites.

+

+	* include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro

+	for ftwinfnt.h.

+	* include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H.

+	(FNT_FontRec): Updated.

+	Move Windows FNT definition to...

+	* include/freetype/ftwinfnt.h: This new file.

+	(FT_WinFNT_HeaderRec): Rename `reserved2' to `reserved1'.

+	* src/base/ftwinfnt.c: New file, providing `FT_Get_WinFNT_Header'.

+	* src/winfonts/winfnt.c (winfnt_header_fields): Updated.

+	Rename `reserved2' to `reserved1'.

+	(fnt_font_load): Updated.

+

+	* src/base/Jamfile, src/base/descrip.mms, src/base/rules.mk:

+	Updated.

+

+2003-01-14  Graham Asher  <[email protected]>

+

+	* include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to

+	the type of the first argument to FT_Matrix_Multiply, which isn't

+	changed -- this adds documentation and convenience.

+

+2003-01-13  Graham Asher  <[email protected]>

+

+	* src/sfnt/ttload.c (tt_face_load_metrics)

+	[FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without

+	horizontal metrics (without the `hmtx' table) are now tolerated if

+	an incremental interface has been specified that has a

+	get_glyph_metrics function, implying that metrics will be supplied

+	from outside.  This happens for certain Type 42 fonts passed from

+	GhostScript.

+

+2003-01-11  David Chester  <[email protected]>

+

+	Patches to the auto-hinter in order to slightly improve the output.

+	Note that everything is controlled through the new

+	FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'.  There are

+	also individual FT_CONFIG_CHESTER_XXX macros to control individual

+	`features'.

+

+	Note that all improvements are enabled by default, but can be

+	tweaked for optimization and testing purposes.  The configuration

+	macros will most likely disappear in the short future.

+

+	* include/freetype/config/ftoption.h

+	(FT_CONFIG_OPTION_CHESTER_HINTS): New macro.

+	(FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE})

+	[FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual

+	features.

+

+	* src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]:

+	[FT_CONFIG_CHESTER_SMALL_F]: Use `AH_BLUE_SMALL_F_TOP'.

+	* src/autohint/ahglyph.c (ah_outline_compute_edges)

+	[FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'.

+	(ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]:

+	Increase threshold for `best_dist'.

+	* src/autohint/ahhint.c (ah_compute_stem_width)

+	[FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif

+	handling.

+	(ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special

+	version of `ah_compute_stem_width'.

+	(ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem

+	alignment when stem widths are less than 1.5 pixels wide centers the

+	stem slightly off-center of the center of a pixel (this increases

+	sharpness and consistency).

+	[FT_CONFIG_CHESTER_SERIF]: Use special version of

+	`ah_compute_stem_width'.

+	* src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add

+	`AH_BLUE_SMALL_F_TOP'.

+

+2003-01-11  David Turner  <[email protected]>

+

+	* include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase

+	size of `reserved2' to avoid memory overwrites.

+

+2003-01-08  Huw Davies  <[email protected]>

+

+	* src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into

+	`reserved2', not `reserved'.

+

+	* src/base/ftobjs.c (find_unicode_charmap): Fixed the error code

+	returned when the font doesn't contain a Unicode charmap.  This

+	allows FT2 to load `symbol.ttf' and a few others correctly since the

+	last release.

+	(open_face): Fix return value.

+

+2003-01-08  Owen Taylor  <[email protected]>

+

+	Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and

+	postscript hinters.

+

+	* src/autohint/ahtypes.h (AH_HinterRec): Add `do_stem_adjust'.

+	* src/autohint/ahhint.c (ah_compute_stem_width): Handle

+	hinter->do_stem_adjust.

+	(ah_hinter_load_glyph): Set hinter->do_stem_adjust.

+

+	* src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add `do_stem_adjust'.

+	* src/pshinter/pshalgo3.c (psh3_hint_align): Use `do_stem_adjust'.

+	(ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT.

+

+	* include/freetype/freetype.h (FT_Render_Mode): Add

+	FT_RENDER_MODE_LIGHT.

+

+	* src/truetype/ttgload.c: Fixing the TrueType loader to handle

+	invalid composites correctly by limiting the recursion depth.

+	(TT_MAX_COMPOSITE_RECURSE): New macro.

+	(load_truetype_glyph): Add argument `recurse_count'.

+	Load a composite only if the numbers of contours is -1, emit error

+	otherwise.

+	(TT_Load_Glyph): Updated.

+

+2003-01-08  David Turner  <[email protected]>

+

+	* Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: Small changes to

+	support the compilation of FreeType 2 as part of larger projects

+	with their own configuration options (only with Jam).

+

+2003-01-07  David Turner  <[email protected]>

+

+	* src/base/ftstroker.c: Probably the last bug-fixes to the stroker;

+	the API is likely to change, however.

+	(ft_stroke_border_close): Don't record empty paths.

+	(ft_stroke_border_get_counts): Increase `num_points' also in for loop.

+	(ft_stroke_border_export): Don't increase `write' twice in for loops.

+	(ft_stroker_outside): Handle `phi' together with `theta'.

+	(FT_Stroker_ParseOutline): New function.

+

+	* src/base/fttrigon.c (FT_Angle_Diff): Fixing function: It returned

+	invalid values for large negative angle differences (resulting in

+	incorrect stroker computations, among other things).

+

+	* src/cache/ftccache.c (ftc_node_hash_unlink): Removing incorrect

+	assertion, and changing code to avoid hash table size contraction.

+

+	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Adding

+	`ftstroker' to default build, as optional component.

+

+2002-12-26  David Turner  <[email protected]>

+

+	* src/gzip/adler32.c, src/gzip/infblock.c, src/gzip/inflate.c,

+	src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,

+	src/gzip/zutil.h: Updates to allow compilation without compiler

+	warnings with LCC-Win32.

+

+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 4.

+	* builds/unix/configure.ac (version_info): Increased to 9:3:3.

+	* builds/unix/configure: Regenerated.

+	* docs/VERSION.DLL: Updated.

+

+2002-12-23  Anthony Fok  <[email protected]>

+

+	* builds/unix/configure.ac, builds/unix/unix-cc.in (LINK_LIBRARY),

+	builds/unix/unix-def.in (SYSTEM_ZLIB): Small fix to configure

+	sub-system on Unix to allow other programs to correctly link with

+	zlib when needed.

+

+2002-12-19  David Turner  <[email protected]>

+

+	* include/freetype/internal/sfnt.h (SFNT_Load_Table_Func): New

+

+2002-12-17  David Turner  <[email protected]>

+

+2002-12-16  David Turner  <[email protected]>

+	well as providing an autoconf fragment provided by Lars Clausen.

+

+	* src/smooth/ftgrays.c (gray_render_conic): Fixed small bug that

+	prevented Bézier arcs with negative vertical coordinates to be

+	rendered appropriately.

+

+2002-12-02  Antoine Leca  <[email protected]>

+

+	* src/base/ftobjs.c: Modified the logic to get Unicode charmaps.

+	Now it loads UCS-4 charmaps when there is one.

+	(find_unicode_charmap): New function.

+	(open_face): Refer to the above one.

+	(FT_Select_Charmap): Idem.

+

+2002-11-29  Antoine Leca  <[email protected]>

+

+	* include/freetype/ftgzip.h: Correct the name of the controlling

+	macro (was __FTXF86_H__ ...).

+

+2002-11-27  Vincent Caron  <[email protected]>

+

+	* builds/unix/unix-def.in, builds/unix/freetype-config.in,

+	builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c

+	[FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib

+	installations if available on the target platform (Unix only).

+

+2002-11-23  David Turner  <[email protected]>

+

+	* src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified

+	charset loader to accept pre-defined charsets, even when the font

+	contains fewer glyphs.  Also enforced more checks to ensure that we

+	never overflow the character codes array in the encoding.

+

+2002-11-22  Antoine Leca  <[email protected]>

+

+	* include/freetype/ttnameid.h: Updated to latest OpenType

+	specification.

+

+2002-11-18  David Turner  <[email protected]>

+

+

+	* Version 2.1.3 released.

+	=========================

+

+

+2002-11-07  David Turner  <[email protected]>

+

+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that

+	caused problems with embedded bitmaps.

+

+	* src/otlayout/otlayout.h, src/otlayout/otlconf.h,

+	src/otlayout/otlgsub.c, src/otlayout/otlgsub.h,

+	src/otlayout/otlparse.c, src/otlayout/otlparse.h,

+	src/otlayout/otlutils.h: Updating the OpenType Layout code, adding

+	support for the first GSUB lookups.  Nothing that really compiles

+	for now though.

+

+	* src/autohint/ahhint.c (ah_align_serif_edge): Disabled serif stem

+	width quantization.  It produces slightly better shapes though this

+	is not distinguishable with many fonts.

+	Remove other dead code.

+

+	* src/Jamfile, src/*/Jamfile: Simplified.

+	Use $(FT2_SRC_DIR).

+

+2002-11-06  David Turner  <[email protected]>

+

+	* include/freetype/freetype.h (FT_LOAD_TARGET_LIGHT): New macro.

+	(FT_LOAD_TARGET, FT_LOAD_TARGET_MODE): Use `& 15' instead of `& 7'.

+

+2002-11-05  David Turner  <[email protected]>

+

+	* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: Added

+	support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify

+	the use of system-wide zlib.

+

+	Note that this macro, as well as

+	TT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore.

+	This allows the build system to define them depending on the

+	configuration (typically by adding -D flags at compile time).

+

+	* src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler

+	warnings in optimized mode relative to the `volatile' local

+	variables.  This was not a compiler bug after all, but the fact that

+	a pointer to a volatile variable is not the same as a volatile

+	pointer to a variable :-)

+

+	The fix was to change

+	  `volatile FT_Byte* p'

+	into

+	  `FT_Byte* volatile p'.

+

+	* src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c

+	(pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in

+	optimized modes.

+

+	* src/gzip/*.[hc]: Modified our zlib copy in order to prevent

+	exporting any zlib function names outside of the component.  This

+	prevents linking problems on some platforms, when applications want

+	to link FreeType _and_ zlib together.

+

+2002-11-05  Juliusz  <[email protected]>

+

+	* src/psaux/psobjs.c (ps_table_add): Modified increment loop in

+	order to implement exponential behaviour.

+

+2002-11-01  David Turner  <[email protected]>

+

+	Added PFR-specific public API.  Fixed the kerning retrieval routine

+	(it returned invalid values when the outline and metrics resolution

+	differ).

+

+	* include/freetype/ftpfr.h, include/freetype/internal/pfr.h: New

+	files.

+

+	* include/freetype/internal/internal.h (FT_INTERNAL_PFR_H): New

+	macro for pfr.h.

+	(pfr_get_kerning, pfr_get_advance, pfr_get_metrics): New functions.

+	(pfr_service_rec): New format interface.

+	(pfr_driver_class): Use `pfr_service_rec'.

+	Replace `pfr_face_get_kerning' with `pfr_get_kerning'.

+	* src/pfr/pfrobjs.c: Remove dead code.

+

+	* src/base/ftobjs.c (ft_glyphslot_clear): Small internal fix to

+	better support bitmap-based font formats.

+

+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Fix handling of

+	`scale'.

+	Fix arguments to `FT_Vector_From_Polar'.

+

+2002-10-31  David Turner  <[email protected]>

+

+	Add support for automatic handling of gzip-compressed PCF files.

+

+	* src/gzip/*: New files, taken from the zlib package (except

+	ftgzip.c).

+

+	* include/freetype/ftgzip.h, src/gzip/ftgzip.c: New files.

+	* include/freetype/config/ftheader.h (FT_GZIP_H): New macro for

+	`ftgzip.h'.

+

+	* src/pcf/pcfdriver.c: Include FT_GZIP_H and FT_ERRORS_H.

+	(PCF_Face_Init): If normal open fails, try to open gzip stream.

+	(PCF_Face_Done): Close gzip stream.

+

+	* include/freetype/internal/pcftypes.h (PCF_Public_FaceRec),

+	src/pcf/pcf.h (PCF_FaceRec): Add `gzip_stream' and `gzip_source'.

+

+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_ZLIB):

+	New macro.

+	(T1_CONFIG_OPTION_DISABLE_HINTER, FT_CONFIG_OPTION_USE_CMAPS

+	FT_CONFIG_OPTION_NO_CONVENIENCE_FUNCS,

+	FT_CONFIG_OPTION_ALTERNATE_GLYPH_FORMATS): Removed.

+

+	(FT_EXPORT, FT_EXPORT_DEF, FT_DEBUG_LEVEL_ERROR,

+	FT_DEBUG_LEVEL_TRACE, FT_DEBUG_MEMORY): Comment out definitions so

+	that platform specific configuration file can override.

+

+	* include/freetype/internal/ftstream.h: Include FT_SYSTEM_H.

+

+2002-10-30  David Turner  <[email protected]>

+

+	* FreeType 2.1.3rc3 released.

+

+2002-10-25  David Turner  <[email protected]>

+

+	* include/freetype/ftcache.h (FT_POINTER_TO_ULONG): New macro.

+	(FTC_FACE_ID_HASH): Rewritten, using FT_POINTER_TO_ULONG.

+

+2002-10-22  Giuseppe Ghibò  <[email protected]>

+

+	* include/freetype/freetype.h (FT_Encoding): Fix entry for latin-2.

+

+2002-10-07  Werner Lemberg  <[email protected]>

+

+	* include/freetype/freetype.h (FT_Open_Face): Use `const' for `args'

+	(suggested by Graham).

+	* src/base/ftobjs.c (FT_Open_Face): Updated.

+	(ft_input_stream_new): Ditto.

+

+2002-10-05  David Turner  <[email protected]>

+

+	Adding support for embedded bitmaps to the PFR driver, and rewriting

+	its kerning loader/handler to use all kerning pairs in a physical

+	font (and not just the first item).

+

+	* src/pfr/pfr.c: Include `pfrsbit.c'.

+	* src/pfr/pfrgload.c: Include `pfrsbit.h'.

+	* src/pfr/pfrload.c (pfr_extra_item_load_kerning_pairs): Rewritten.

+	FT_LOAD_NO_RECURSE is set.

+	Load embedded bitmaps only if FT_LOAD_NO_BITMAP isn't set.

+

+	* src/tools/docmaker/content.py, src/tools/docmaker/sources.py,

+	src/tools/docmaker/tohtml.py: Fixing a few nasty bugs.

+

+	* src/sfnt/ttcmap0.c (tt_cmap4_validate): The validator for format 4

+	sub-tables is now capable of dealing with invalid `length' fields at

+	the start of the sub-table.  This allows fonts like `mg______.ttf'

+	(i.e.  Marriage) to return accurate charmaps.

+

+	* docs/CHANGES: Updated.

+

+2002-10-05  Werner Lemberg  <[email protected]>

+

+	* src/smooth/ftgrays.c (SUBPIXELS): Add cast to `TPos'.

+	Update all callers.

+	the erroneous FT_ENCODING_SYMBOL).

+

+	* builds/unix/unix-def.in (datadir): Initialize it (thanks to

+	Anthony Fok).

+

+2002-08-29  David Turner  <[email protected]>

+

+	Slight modification to the Postscript hinter to slightly increase

+	the contrast of smooth hinting.  This is very similar to what the

+	auto-hinter does when it comes to stem width computations.  However,

+	it produces better results with well-hinted fonts.

+

+	* include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Add hint

+	mode to `init' member function.

+	(T1_DecoderRec): Add hint mode.

+	vertical and horizontal hints and snapping.

+

+	* README, docs/CHANGES: Updating for the 2.1.3 release.

+

+2002-08-27  David Turner  <[email protected]>

+

+	* Massive re-formatting changes to many, many source files.  I don't

+	want to list them all here.  The operations performed were all

+	logical transformations of the sources:

+

+	- trying to convert all enums and constants to CAPITALIZED_STYLE,

+	  #with define definitions like

+

+	    #define my_old_constants   MY_NEW_CONSTANT

+

+	- big, big update of the documentation comments

+

+	* include/freetype/freetype.h, src/base/ftobjs.c,

+	src/smooth/ftsmooth.c, include/freetype/ftimage.h: Adding support

+	for LCD-optimized rendering though the new constants/enums:

+

+	  FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V

+	  FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

+

+	This is still work in progress, don't expect everything to work

+	correctly though most of the features have been implemented.

+

+	* Adding new FT_LOAD_XXX flags, used to specify both hinting and

+	rendering targets:

+

+	  FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering

+	  FT_LOAD_TARGET_MONO   :: monochrome bitmaps

+	  FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated

+	                           hinting & rendering

+	  FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated

+	                           hinting & rendering

+

+	Note that FT_LOAD_TARGET_NORMAL is 0, which means that the default

+	behaviour of the font engine is _unchanged_.

+

+	* include/freetype/ftimage.h

+	(FT_Outline_{Move,Line,Conic,Cubic}To_Func): Renamed to...

+	(FT_Outline_{Move,Line,Conic,Cubic}ToFunc): This.

+	have been updated accordingly.

+

+2002-08-23  Graham Asher  <[email protected]>

+

+	* src/cff/cffgload.c (cff_operator_seac)

+	[FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not

+	incremental in the case of CFF but just using callbacks to get glyph

+	recipes) pass the character code, not the glyph index, to the

+	get_glyph_data function; they have no valid charset table.

+

+	* src/cff/cffload.c (cff_font_load): Removed special cases for

+	FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF

+	fonts provided via the incremental interface now have to conform

+	more closely to the CFF font format.

+

+	* src/cff/cffload.h (cff_font_load): Removed argument now unneeded.

+

+	* src/cff/cffobjs.c (cff_face_init): Changed call to cff_font_load

+	compiler warnings and resolve shadowing of local variables.

+

+2002-08-21  David Turner  <[email protected]>

+

+	The automatic and Postscript hinter now automatically detect

+	inflection points in glyph outlines and treats them specially.  This

+	is very useful to prevent nasty effect like the disappearing

+	diagonals of `S' and `s' in many, many fonts.

+

+	* src/autohint/ahtypes.h (ah_flag_inflection): New macro.

+	* src/autohint/ahangles.c (ah_angle_diff): New function.

+

+	* include/freetype/freetype.h: Changing the type of the `load_flags'

+	parameter from `FT_Int' to `FT_Int32', this in order to support more

+	options.  This should only break binary and/or source compatibility

+	on 16-bit platforms (Atari?).

+	(FT_LOAD_NO_AUTOHINT): New macro.

+

+	* src/base/ftobjs.c (FT_Load_Glyph): Updated.

+	Handle FT_LOAD_NO_AUTOHINT.

+	(FT_Load_Char): Updated.

+

+	* src/pshinter/pshalgo3.c, src/base/ftobjs.c, src/base/ftobject.c,

+2002-08-20  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttgload.c (TT_Get_Metrics): Add guard for k = 0.

+	src/pshinter/pshglob.c, src/pshinter/pshrec.c,

+	src/autohint/ahmodule.c [DEBUG_HINTER]: Removing compiler warnings

+	enum values.

+	(psh3_point_{is,set}_{extremum,positive,negative,edge_min,edge_max}):

+	New macros.

+	(PSH3_PointRec): New members `flags2' and `org_v'.

+	(PSH3_POINT_EQUAL_ARG, PSH3_POINT_ANGLE): New macros.

+

+	* src/pshinter/pshalgo3.c [DEBUG_HINTER]: Removing compiler

+	warnings.

+	(COMPUTE_INFLEXS): New macro.

+

+	* src/type1/t1load.c (T1_Open_Face): Tolerate a face with no

+	charstrings if there is an incremental loading interface.  Type 1

+	faces supplied by PostScript interpreters like GhostScript will

+

+2002-08-01  Graham Asher  <[email protected]>

+

+	Modified incremental loading interface to be closer to David's

+	preferences.  The header freetype.h is not now affected, the

+

+2002-07-18  Graham Asher  <[email protected]>

+

+	Added types and structures to support incremental typeface loading.

+	The FT_Incremental_Interface structure, defined in freetype.h, is

+	designed to be passed to FT_Open_Face to provide callback functions

+	from PostScript that do not necessarily provide all, or any, glyph

+	information, when first opened.

+

+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):

+	New configuration macro to enable incremental face loading.  By

+	* src/cid/cidgload.c (cid_load_glyph)

+	[FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system

+	for the CID driver.

+

+	Changes to support incremental Type 42 fonts: Assume a font has

+	glyphs if it has an incremental interface object.

+	(T1_Parse_Glyph_And_Get_Char_String): This.

+

+2002-07-11  David Turner  <[email protected]>

+

+2005-05-28  David Turner  <[email protected]>

+

+	* docs/CHANGES: Updating file for next release (2.1.1).

+

+	* src/bdf/bdflib.c: Removing compiler warnings.

+

+	* include/freetype/ftxf86.h, src/base/ftxf86.c: New files.

+	They provide a new API (FT_Get_X11_Font_Format) to retrieve an

+	X11-compatible string describing the font format of a given face.

+	This was put in a new optional base source file, corresponding to a

+	new public header (named FT_XFREE86_H since this function should

+	only be used within the XFree86 font server IMO).

+

+	* include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not

+	documented yet).

+

+	* src/base/fttype1.c: New file, providing two new API functions

+	(FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names).

+	* include/freetype/t1tables.h: Updated.

+

+	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:

+	Updating build control files for the new files `ftxf86.c' and

+	`fttype1.c' in src/base.

+

+	* src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that

+	prevented family blue zones substitution from happening correctly.

+

+2002-05-28  Werner Lemberg  <[email protected]>

+	but FT_STREAM_READ.

+	Declare `stream' variable.

+

+	* src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math

+	with calls to `FT_MulDiv'.

+

+2002-05-28  David Turner  <[email protected]>

+

+	Fixing the SFNT name table loader to support various buggy fonts.

+	It now ignores empty name entries, entries with invalid pointer

+	Offsets and certain fonts containing tables with broken

+	`storageOffset' fields.

+

+	Name strings are now loaded on demand, which reduces the memory

+	requirements for a given FT_Face tremendously (for example, the name

+	table of Arial.ttf is about 10Kb and contains 70 names).

+

+	This is a temporary fix.  The whole name table loader and interface

+	will be rewritten in a much more cleanly way shortly, once CSEH have

+	been introduced in the sources.

+

+	* include/freetype/internal/tttypes.h (TT_NameEntryRec): Change

+	type of `stringOffset' to FT_ULong.

+	(TT_NameTableRec): Change type of `numNameRecords' and

+	`storageOffset' to FT_UInt.

+	Replace `storage' with `stream'.

+	* src/base/ftnames.c (FT_Get_Sfnt_Name): Load name on demand.

+	* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.

+	Make code more robust.

+	* src/sfnt/sfobjs.c (TT_NameEntry_ConvertFunc): New typedef.

+	(tt_face_get_name): Use it.

+	Make code more robust.

+	* src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays.

+	Handle invalid `storageOffset' data better.

+	Set length fields to zero for invalid or ignored data.

+	Remove code within FT_DEBUG_LEVEL_TRACE.

+	(TT_Free_Names): Updated.

+

+2002-05-24  Tim Mooney  <[email protected]>

+

+	* builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and

+	FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be

+	rebuilt from sources.  Set macro serial to 1, and use third argument

+	to AC_DEFINE for our two custom symbols, so ftconfig.in could one day

+	be rebuilt with autoheader (not recommended now, ftconfig.in is a

+	custom source file)

+

+2002-05-22  Werner Lemberg  <[email protected]>

+

+	* include/freetype/config/ftheader.h (FT_BEZIER_H): Removed.

+	(FT_BDF_H): New macro for accessing `ftbdf.h'.

+

+	* src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy

+	for undocumented, obsolete opcode 15.

+

+2002-05-21  David Turner  <[email protected]>

+

+	* src/bdf/bdflib.c: Removed compiler warning, and changed all tables

+	to the `static const' storage specifier (instead of simply

+	`static').

+

+	* src/type42/t42drivr.c (hexval): Use more efficient code.

+	Removing compiler warnings.

+	* src/bdf/bdfdrivr.c: Removing compiler warnings.

+

+	* include/freetype/internal/ftbdf.h, src/base/ftbdf.c,

+	src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk

+	(FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings

+	from a face.  This is much cleaner than accessing the internal types

+	`BDF_Public_Face' defined in FT_INTERNAL_BDF_TYPES_H.

+

+2002-05-21  Werner Lemberg  <[email protected]>

+

+	* src/bdf/README: Mention Microsoft's SBIT tool.

+	New macro.

+

+2002-05-20  Werner Lemberg  <[email protected]>

+

+	* include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field

+	`num_grays' for specifying the number of used gray levels.

+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.

+

+2002-05-19  Werner Lemberg  <[email protected]>

+

+	Adding a driver for BDF fonts written by Francesco Zappa Nardelli

+	<[email protected]>.  Heavily modified by me to

+

+	* src/type1/t1load.h (T1_Loader): Renamed to...

+	(T1_LoaderRec): This.

+2002-05-06  Werner Lemberg  <[email protected]>

+

+	* README: Add a note regarding libttf vs. libfreetype.

+

+2002-05-05  Werner Lemberg  <[email protected]>

+

+	FreeType 2 can now be built in an external directory with the

+	configure script also.

+

+	* builds/freetype.mk (INCLUDES): Add `OBJ_DIR'.

+

+	* builds/unix/detect.mk (have_mk): New variable to test for

+	external build.

+	(unix-def.mk): Defined according to value of `have_mk'.

+	* builds/unix/unix.mk (have_mk): New variable to test for

+	external build.

+	Select include paths for unix-def.mk and unix-cc.mk according

+	to value of `have_mk'.

+	* builds/unix/unix-def.in (OBJ_BUILD): New variable.

+	(DISTCLEAN): Use it.

+	* builds/unix/unix-cc.in (LIBTOOL): Define default value only

+	if not yet defined.

+	* builds/unix/install.mk (install): Use `OBJ_BUILD' for installing

+	freetype-config.

+

+	* configure: Don't depend on bash features.

+	(ft2_dir, abs_curr_dir, abs_ft2_dir): New variables (code

+	partially taken from Autoconf).

+	Build a dummy Makefile if not building in source tree.

+

+	* docs/INSTALL: Document it.

+

+2002-05-04  David Turner  <[email protected]>

+

+	* src/truetype/ttgload.c (TT_Load_Glyph): Finally fixing the last

+	bug that prevented FreeType 2.x and FreeType 1.x to produce

+	bit-by-bit identical monochrome glyph bitmaps with native TrueType

+	hinting.  The culprit was a single-bit flag that wasn't set

+	correctly by the TrueType glyph loader.

+

+	* src/otlayout/otlayout.h, src/otlayout/otlbase.c,

+	src/otlayout/otlbase.h, src/otlayout/otlconf.h,

+	src/otlayout/otlgdef.c, src/otlayout/otlgdef.h,

+	src/otlayout/otlgpos.c, src/otlayout/otlgpos.h,

+	src/otlayout/otltable.c, src/otlayout/otltable.h,

+	src/otlayout/otltags.h: New OpenType Layout source files.  The

+2002-05-02  Werner Lemberg  <[email protected]>

+

+	* src/sfnt/ttcmap0.c (tt_cmap4_char_index): Fix serious typo

+	(0xFFFU -> 0xFFFFU).

+

+2002-05-01  Werner Lemberg  <[email protected]>

+

+	* docs/INSTALL: Fix URL of makepp.

+

+2002-05-01  David Turner  <[email protected]>

+

+	* src/sfnt/sfobjs.c (tt_face_get_name): Fixing a bug that caused

+	were opened.

+

+	* src/sfnt/ttload.c (TT_Load_Names): Applied a small work-around to

+	manage fonts containing a broken name table (e.g. `hya6gb.ttf').

+

+	* src/sfnt/ttcmap0.c (tt_cmap4_validate): Fixed over-restrictive

+	validation test.  The charmap validator now accepts overlapping

+	ranges in format 4 charmaps.

+

+	* src/sfnt/ttcmap0.c (tt_cmap4_char_index): Switched to a binary

+	search algorithm.  Certain fonts contain more than 170 distinct

+	segments!

+	unexpected exception (which shouldn't happen in theory).

+

+	* include/freetype/internal/fthash.h, src/base/fthash.c: New files.

+	This is generic implementation of dynamic hash tables using a linear

+	algorithm (to get rid of `stalls' during resizes).  In the future

+	this will be used in at least three parts of the library: the cache

+	sub-system, the object sub-system, and the memory debugger.

+

+	* src/base/Jamfile: Updated.

+

+	* include/freetype/internal/internal.h (FT_INTERNAL_HASH_H,

+	FT_INTERNAL_OBJECT_H): New macros.

+

+	* include/freetype/internal/ftcore.h: New file to group all new

+	definitions related to exception handling and memory management.  It

+	is very likely that this file will disappear or be renamed in the

+	future.

+

+	* include/freetype/internal/ftobject.h, include/freetype/ftsysmem.h:

+	Adding comments to better explain the object sub-system as well as

+	the new memory manager interface.

+

+2002-04-30  Wenlin Institute (Tom Bishop)  <[email protected]>

+

+	* src/base/ftmac.c (p2c_str): Removed.

+	(file_spec_from_path) [TARGET_API_MAC_CARBON]: Added support for

+	OS X.

+	(is_dfont) [TARGET_API_MAC_CARBON]: Define only for OS X.

+	Use functionality of old p2c_str directly.

+	Add safety checks.

+	(read_lwfn): Initialize `size_p'.

+	Check for size_p == NULL.

+	(new_memory_stream, open_face_from_buffer): Updated to FreeType 2.1.

+	(FT_New_Face_From_LWFN): Remove unused variable `memory'.

+	Remove some dead code.

+	(FT_New_Face_From_SFNT): Remove unused variable `stream'.

+	(FT_New_Face_From_dfont) [TARGET_API_MAC_CARBON]: Define only for

+	OS X.

+	src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h: Updated

+	the SFNT charmap support to use FT_CMaps.

+

+	* include/freetype/fterrdef.h: New file.

+	* include/freetype/fterrors.h: Include it.  It contains all error

+	codes.

+	* include/freetype/config/ftheader.h (FT_ERROR_DEFINITIONS_H): New

+	macro.

+

+	* include/freetype/internal/ftmemory.h, and a lot of other files:

+	Changed the names of memory macros.  Examples:

+	  REALLOC   = >FT_REALLOC

+

+	FT_NEW was introduced to allocate a new object from a _typed_

+	pointer.

+

+	Note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by

+	FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer

+	arguments.

+

+	  FILE_Skip    => FT_STREAM_SKIP

+	  FILE_Read    => FT_STREAM_READ

+	  ACCESS_Frame => FT_FRAME_ENTER

+

+	* include/freetype/internal/cfftypes.h, src/cff/*.c: Updating the

+	type definitions of the CFF font driver.

+

+	  CFF_Font  => CFF_FontRec

+

+2002-03-06  Werner Lemberg  <[email protected]>

+

+	* src/type1/t1objs.c (T1_Face_Init), src/cff/cffobjs.c

+	(CFF_Face_Init), src/cid/cidobjs.c (CID_Face_Init): Removing the bug

+	that returned global BBox values in 16.16 fixed format (instead of

+	integer font units).

+

+	* src/cid/cidriver.c (cid_get_postscript_name): Fixed a bug that

+	caused the CID driver to return Postscript font names with a leading

+	slash (`/') as in `/MOEKai-Regular'.

+

+	* src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),

+	src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so

+	that it accepts broken fonts like `foxjump.ttf', which made FreeType

+	crash when trying to load them.

+

+	Also improved the name table parser to be able to load

+	Windows-encoded entries before Macintosh or Unicode ones, since it

+	seems some fonts don't have reliable values here anyway.

+

+	* include/freetype/internal/psnames.h: Add typedef for

+	`PSNames_Service'.

+

+2002-03-05  Werner Lemberg  <[email protected]>

+

+	* builds/unix/aclocal.m4, builds/unix/ltmain.sh: Update to libtool

+	1.4.2.

+	Apply a small patch for AIX to make shared libraries work (this

+2002-02-28  David Turner  <[email protected]>

+

+	* include/freetype/ftconfig.h: Changed `FT_LOCAL xxxx' to

+	`FT_LOCAL( xxxx )' everywhere in the source.  The same goes for

+	`FT_LOCAL_DEF xxxx' which is translated to `FT_LOCAL_DEF( xxxxx )'.

+

+	* include/freetype/freetype.h (FREETYPE_MINOR, FREETYPE_PATCH):

+	Changing version to 2.1.0 to indicate an unstable branch.

+	Added the declarations of FT_Get_First_Char and FT_Get_Next_Char.

+

+	* src/base/ftobjs.c: Implement FT_Get_First_Char and

+	FT_Get_Next_Char.

+

+	* include/freetype/t1tables.h: Renaming structure types.  This

+

+	  typedef  T1_Struct_

+	  {

+	  } T1_Struct;

+

+	becomes

+

+	  typedef  PS_StructRec_

+	  {

+	  } PS_StructRec, *PS_Struct;

+

+	  typedef PS_StructRec  T1_Struct;  /* backward compatibility */

+

+	Hence, we increase the coherency of the source code by effectively

+	using the `Rec' prefix for structure types.

+

+2002-02-27  David Turner  <[email protected]>

+

+	* src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the

+	names table loader.  Invalid individual name entries are now handled

+	correctly.  This allows the loading of very buggy fonts like

+	`foxjump.ttf' without allocating tons of memory and causing crashes.

+

+	* src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: Adding (still

+	experimental) code for OpenType Layout tables validation and

+	parsing.

+

+	* src/type1/t1cmap.h, src/type1/t1cmap.c: Adding (still

+	experimental) code for Type 1 charmap processing.

+

+	* src/sfnt/ttcmap0.c: New file.  It contains a new, still

+	experimental SFNT charmap processing support.

+

+	* include/freetype/internal/ftobjs.h: Adding validation support as

+	well as internal charmap object definitions (FT_CMap != FT_CharMap).

+

+2002-02-24  David Turner  <[email protected]>

+

+	* Renaming stream functions to the FT_<Subject>_<Action> scheme:

+	  FT_Get_XXXX       => FT_Stream_Get_XXXX

+	  FT_Read_XXXX      => FT_Stream_Read_XXXX

+

+	  FT_New_Stream( filename, stream ) =>

+	    FT_Stream_Open( stream, filename )

+

+	    (The function doesn't create the FT_Stream structure, it simply

+	    initializes it for reading.)

+

+	  FT_New_Memory_Stream( library, FT_Byte*  base, size, stream ) =>

+	    FT_Stream_Open_Memory( stream, const FT_Byte* base, size )

+

+	  FT_Done_Stream  => FT_Stream_Close

+	  FT_Stream_IO    => FT_Stream_IOFunc

+	  FT_Stream_Close => FT_Stream_CloseFunc

+

+	  ft_close_stream => ft_ansi_stream_close (in base/ftsystem.c only)

+	  ft_io_stream    => ft_ansi_stream_io    (in base/ftsystem.c only)

+

+	* src/base/ftutil.c: New file.  Contains all memory and list

+	management code (previously in `ftobjs.c' and `ftlist.c',

+	respectively).

+

+	* include/freetype/internal/ftobjs.h: Moving all code related to

+	glyph loaders to ...

+	* include/freetype/internal/ftgloadr.h: This new file.

+	`FT_GlyphLoader' is now a pointer to the structure

+	`FT_GlyphLoaderRec'.

+	(ft_glyph_own_bitmap): Renamed to ...

+	(FT_GLYPH_OWN_BITMAP): This.

+	* src/base/ftobjs.c: Moving all code related to glyph loaders

+	to ...

+	Some stuff from ftdebug.h has been moved to ...

+

+	* include/freetype/internal/fttrace.h: New file, to define the trace

+	levels used for debugging.  It is used both to define enums and

+	toggle names for FT2_DEBUG.

+

+	* include/freetype/internal/internal.h: Updated.

+

+	* src/base/ftobjs.c, src/base/ftstream.c: Updated.

+

+	* include/freetype/fterrors.h: Adding `#undef FT_ERR_CAT' and

+2006-05-03  David Turner  <[email protected]>

+

+	Allow compilation again with C++ compilers.

+

+	* include/freetype/internal/ftmemory.h (FT_ASSIGNP,

+	FT_ASSIGNP_INNER): New macros which do the actual assignment, and

+	Update callers accordingly.

+

+2006-05-03  Werner Lemberg  <[email protected]>

+

+	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.

+

+2006-05-02  Werner Lemberg  <[email protected]>

+

+	* include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++).

+	(FT_ALLOC): Remove redundant redefinition.

+

+	* builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use

+

+	* src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.

+

+	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:

+	Remove `extern'.

+

+2006-05-02  David Turner  <[email protected]>

+

+	Update the memory management functions and macros to safely deal

+	with array size buffer overflows.  This corresponds to attempts to

+	allocate arrays that are too large.  For an example, consider the

+	following code:

+

+	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *

+	  count ); for ( nn = 0; nn < count; nn++ )

+	    array[nn] = read_item_from_file();

+

+	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the

+	multiplication overflows, and the array allocated os smaller than

+	the data read from the file.  In this case, the heap will be

+	trashed, and this can be used as a denial-of-service attack, or make

+	the engine crash later.

+

+	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new

+	count is no larger than `FT_INT_MAX/item_size', otherwise a new

+	error code `FT_Err_Array_Too_Large' will be returned.

+

+	Note that the memory debugger now works again when FT_DEBUG_MEMORY

+	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding

+	code is now the default.

+

+

+	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:

+	Don't use `extern'.

+

+	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error

+	code.

+

+	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)

+	[FT_DEBUG_MEMORY]: New macro.

+	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.

+	(ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug,

+	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

+	(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,

+	FT_MEM_FREE): Redefine.

+	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,

+	FT_MEM_QRENEW_ARRAY): Redefine.

+	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,

+	FT_MEM_QREALLOC_MULT): New macros.  Update callers where

+	appropriate.

+	(FT_MEM_SET_ERROR): Slightly redefine.

+

+

+	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)

+	[FT_DEBUG_MEMORY]: New global variables, replacing...

+	(FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and

+	`line_no'.  Update all callers.

+	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer

+	overflow.

+	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,

+	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

+

+	* src/base/ftmac.c (read_lwfn): Catch integer overflow.

+	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.

+	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.

+	(ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite.

+

+

+	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,

+	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the

+	place where the frames were entered, extracted, exited or released

+	in the memory debugger.

+

+	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:

+	Call ft_mem_free.

+	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.

+	(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.

+

+2006-04-30  suzuki toshiya  <[email protected]>

+

+	* src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos

+	initialization, remove extra cast to copy to pfb_lenpos.  This fixes

+	parsing of PFB fonts with MacOS resource fork (bug introduced

+	2003-09-11).  Patch provided by Huib-Jan Imbens <[email protected]>.

+

+2006-04-29  Werner Lemberg  <[email protected]>

+

+	Further C library abstraction.  Based on a patch from

+	ft_fopen, ft_fclose, ft_fseek, ft_ftell, ft_fread, ft_smalloc,

+	C library functions.  Update all users accordingly (and catch some

+	other places where the C library function was used instead of the

+	wrapper functions).

+

+	* src/base/ftsystem.c: Don't include stdio.h and stdlib.h.

+	* src/gzip/zutil.h [MSDOS && !(__TURBOC__ || __BORLANDC__)]: Don't

+	include malloc.h.

+

+

+	* builds/unix/unix-def.in (datarootdir): Define, for autoconf 2.59c

+	and forthcoming versions.

+	ft_mem_qrealloc): Return an error if a negative size is passed in

+	parameters.

+

+	* src/cache/ftccache.c (ftc_node_destroy): Mark as FT_BASE_DEF since

+	it needs to be exported for rogue clients.

+

+	* src/pshinter/pshglob.c (psh_blues_set_zones_0): Prevent problems

+	with malformed fonts which have an odd number of blue values (these

+2006-02-27  Chia-I Wu  <[email protected]>

+

+	* src/base/ftobjs.c (GRID_FIT_METRICS): New macro.

+	(ft_glyphslot_grid_fit_metrics, FT_Load_Glyph) [GRID_FIT_METRICS]:

+	Re-enable glyph metrics grid-fitting.  It is now done in the base

+

+	* docs/CHANGES: Updated to reflect many fixes for backward

+

+2006-02-26  David Turner  <[email protected]>

+

+	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Re-enable

+	conservative rounding of metrics to avoid breaking clients like

+

+2006-02-25  Werner Lemberg  <[email protected]>

+

+	* devel/ftoption.h: Synchronize with

+	etc., to fix compiler warnings (and C++ compiling errors).

+

+	* src/cache/ftcbasic.c: Fix `-Wmissing-prototypes' warnings with

+	gcc.

+

+	* builds/unix/ftsystem.c: Don't include FT_INTERNAL_OBJECTS_H but

+

+	* include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap),

+

+2006-02-24  David Turner  <[email protected]>

+

+	* Release candidate VER-2-2-0-RC3.

+	----------------------------------

+

+	* src/cache/ftcbasic.c: Correct compatibility hack bug.

+

+2006-02-24  Chia-I Wu  <[email protected]>

+

+	* include/freetype/freetype.h (FT_Size_RequestRec): Change the type

+	of `width' and `height' to `FT_Long'.

+	(enum FT_Size_Request_Type), src/base/ftobjs.c (FT_Request_Metrics):

+	New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales

+	directly.

+

+2006-02-23  David Turner  <[email protected]>

+

+	Two BDF patches from Debian libfreetype6 for 2.1.10.

+

+	* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width

+	glyphs.

+	Fix a problem with large encodings.

+

+

+	Fix binary compatibility issues for gnustep-back (GNUstep backend

+	module) which still crashes under Sarge.

+

+	* src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,

+	FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data

+	structures and enumerations.

+	(FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New

+	compatibility code.

+

+	* src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to

+	support rogue clients compiled against 2.1.7 to work correctly.

+	This probably explains the GNUstep crashes with the second release

+	candidate.

+

+2006-02-23  Chia-I Wu  <[email protected]>

+

+	* include/freetype/ftoutln.h (enum FT_Orientation): New value

+	`FT_ORIENTATION_NONE'.

+

+	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,

+	ft_contour_enclosed, ft_outline_get_orientation): Another version of

+	`FT_Outline_Get_Orientation'.  This version differs from the public

+	one in that each part (contour not enclosed in another contour) of the

+	outline is checked for orientation.

+	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.

+

+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and

+	use bitmap's embolden routine when the outline one failed.

+

+2006-02-22  Chia-I Wu  <[email protected]>

+

+	* modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI

+	compatibility.

+

+	* src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak.

+

+	* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,

+	tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit

+	loading.  (Only tested with bit aligned sbit with x_pos == 0.)

+

+	* src/truetype/ttpload.c (tt_face_load_hdmx,

+	tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not

+	actually used.

+

+2006-02-21  David Turner  <[email protected]>

+

+	Add a new API named FT_Get_TrueType_Engine_Type to determine whether

+	we have a patented, unpatented, or unimplemented TrueType bytecode

+	interpreter.

+

+	The FT_Get_Module_Flags API was removed consequently.

+

+	* include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed.

+	Replaced with...

+	(FT_Get_TrueType_Engine_Type): This.

+	(FT_TrueTypeEngineType): New enumeration.

+

+	* include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H):

+	New macro.

+

+	* src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.

+	(FT_Module_Get_Flags): Removed.  Replaced with...

+	(FT_Get_TrueType_Engine_Type): This.

+

+	* src/truetype/ttdriver.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.

+	(tt_service_truetype_engine): New service structure.

+	(tt_services): Register it.

+

+	* include/freetype/internal/services/svtteng.h: New file.

+

+

+	* src/sfnt/sfobjs.c (sfnt_load_face): Fix silly bug that prevented

+	embedded bitmaps from being correctly listed and used.

+

+

+	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization

+	if FT_CONFIG_OPTION_OLD_INTERNALS is used.  The is necessary because

+	libXfont is directly accessing the HMTX data, unfortunately.

+	Fix some compiler warnings.

+	(tt_face_get_metrics): Ditto.

+

+

+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of

+	character advances.

+

+2006-02-20  David Turner  <[email protected]>

+

+	Support binary compatibility with the X.Org server's Xfont library.

+	Note that this change unfortunately prevents memory optimizations

+	for the embedded bitmap loader.

+

+	* include/freetype/internal/sfnt.h (SFNT_Interface): Move

+	`set_sbit_strike' and `load_sbit_metrics' fields to the location of

+	version 2.1.8.

+

+	* src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call

+	FT_Size_Request.

+	(sfnt_interface): Updated.

+

+	* src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load

+	ttsbit0.c.

+	(tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static.

+

+	* src/sfnt/ttsbit.h: Updated.

+

+2006-02-17  David Turner  <[email protected]>

+

+	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported

+	functions anymore.  This ensures that all FT_BASE internal functions

+	are available for dynamic linking.

+

+	* include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE,

+	FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec,

+	FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New,

+	FTC_OldImageDesc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx,

+	ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup,

+	FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup)

+	[FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the

+	cache sub-system.  We try to recognize old legacy signatures with a

+	gross hack (hope it works).

+

+2006-02-17  Werner Lemberg  <[email protected]>

+

+	* devel/ftoption.h: Synchronize with

+	include/freetype/config/ftoption.h.

+

+2006-02-16  David Turner  <[email protected]>

+

+	Massive changes to the internals to respect the internal object

+	layouts and exported functions of FreeType 2.1.7.  Note that the

+	cache sub-system cannot be fully retrofitted, unfortunately.

+

+	* include/freetype/config/ftoption.h

+	(FT_CONFIG_OPTION_OLD_INTERNALS): New macro.

+

+	* include/freetype/ftcache.h, include/freetype/cache/ftccache.h,

+	src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c:

+	Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data

+	structures.

+

+	Move newly added structure elements to the end of the affected

+	structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is

+	defined) to assure binary compatibility with older FreeType

+	versions.

+	Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old

+	functions:

+

+	  ft_stub_set_char_sizes

+	  ft_stub_set_pixel_sizes

+

+	Rename the following internal functions to provide the old function

+	names as stubs:

+

+	  FT_Alloc          -> ft_mem_alloc

+	  FT_QAlloc         -> ft_mem_qalloc

+	  FT_Realloc        -> ft_mem_realloc

+	  FT_QRealloc       -> ft_mem_qrealloc

+	  FT_Free           -> ft_mem_free

+	  FT_Alloc_Debug    -> ft_mem_alloc_debug

+	  FT_QAlloc_Debug   -> ft_mem_qalloc_debug

+	  FT_Realloc_Debug  -> ft_mem_realloc_debug

+	  FT_QRealloc_Debug -> ft_mem_qrealloc_debug

+	  FT_Free_Debug     -> ft_mem_free_debug

+

+2006-02-15  Chia-I Wu  <[email protected]>

+

+	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove

+	unused `max_points' and `max_contours'.

+

+	* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c

+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.

+

+	* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused

+	`max_components'.

+

+	* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused

+	`loadSize' and `loadStack'.

+

+	* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),

+	src/sfnt/ttload.c (tt_face_load_maxp): Update.

+

+	* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c

+	(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix

+	compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not

+	defined.

+

+	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix

+	possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.

+	(finally!)

+

+

+	For most OpenType tables, `tt_face_load_xxxx' simply loads the table

+	and `face->root' is set later in `sfnt_load_face'.  Here, we try to

+	make this work for _all_ tables.  Also improve tracing messages.

+

+	* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,

+	src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and

+	then exit.  Error handling or setting face->root is done later in

+	`sfnt_load_face'.

+

+	* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.

+	Mac bitmap-only fonts are not scalable.

+	Check that `face->header.Units_Per_EM' is not zero.

+	(LOAD_, LOADM_): Emit pretty trace messages.

+

+	* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics

+	from `eblc'.

+

+	* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c

+	(load_format_20, load_format_25, tt_face_get_ps_name): Use

+	face->max_profile.numGlyphs, instead of face->root.num_glyphs.

+

+2006-02-14  Werner Lemberg  <[email protected]>

+

+	* include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in

+	documentation that negative strength values are possible.

+	Give an example call.

+

+	* include/freetype/freetype.h (FT_GlyphSlotRec): Improve

+	documentation of `outline' field.

+

+	* src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H.

+	* src/sfnt/sfdriver.c: Include ttmtx.h.

+

+	* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.

+

+2006-02-14  Chia-I Wu  <[email protected]>

+

+	* src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.

+

+2006-02-14  Chia-I Wu  <[email protected]>

+

+	* src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply

+	return error if table is missing.

+	Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.

+

+	* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics

+	tables.  The last change makes Mac bitmap-only font not load and

+	this fixes it.

+

+	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation

+	error when FT_CONFIG_OPTION_INCREMENTAL is defined.

+

+2006-02-13  Chia-I Wu  <[email protected]>

+

+	Clean up the SFNT_Interface.  In this final pass, `load_hmtx' is

+	split from `load_hhea'.

+

+	* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,

+	src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.

+

+	* src/sfnt/sfobjs.c (sfnt_load_face): Update.

+

+2006-02-13  Chia-I Wu  <[email protected]>

+

+	* src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of

+	code...

+

+2006-02-13  Chia-I Wu  <[email protected]>

+

+	Clean up the SFNT_Interface.  In this pass, we want to treat the

+	font directory (offset table and table directory) as a normal table

+	like the others.  This also means that TTCs are no longer recognized

+	there but in `init_face'.

+

+	* include/freetype/internal/sfnt.h (SFNT_Interface),

+	src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are

+	combined and renamed to `load_font_dir'.

+

+	* src/sfnt/ttload.h, src/sfnt/ttload.c:

+	s/sfnt_dir_check/check_table_dir/.

+	`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.

+	`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined

+	and renamed to `tt_face_load_font_dir'.

+

+	* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.

+

+2006-02-13  Chia-I Wu  <[email protected]>

+

+	Clean up the SFNT_Interface.  Table loading functions are now named

+	after the tables' tags; `hdmx' is TrueType-specific and thus the

+	code is moved to the truetype module; `get_metrics' is moved here

+	from the truetype module so that the code can be shared with the cff

+	module.

+

+	This pass involves no real changes.  That is, the code is moved

+	verbatim mostly.  The only exception is the return value of

+	`tt_face_get_metrics'.

+

+	* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,

+	src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,

+	src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,

+	src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.

+

+	* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files.  Metrics-related

+	tables' loading and parsing code is moved to here.

+	Move `tt_face_get_metrics' here from the truetype module.  The

+	return value is changed from `void' to `FT_Error'.

+

+	* include/freetype/internal/fttrace.h: New trace: ttmtx.

+

+	* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and

+	parsing code is moved here.

+	New function `tt_face_load_prep' split from `tt_face_load_fpgm'.

+	`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

+

+	* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

+

+	* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

+

+2006-02-11  Chia-I Wu  <[email protected]>

+

+	* src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug...

+

+	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Use

+	AF_LatinMetricsRec as the dummy metrics because we cast the metrics

+	to it later in `af_latin_hints_link_segments'.

+

+2006-02-11  Chia-I Wu  <[email protected]>

+

+	* include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define

+	to enable autofit CJK script support.  (#define'd by default.)

+

+	* src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro.

+

+	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure

+	that `edge_distance_threshold' is always set.

+	(af_latin_hints_link_segments): Potential divide-by-zero bug.

+	Use latin constant in the scoring formula.

+

+	* src/autofit/afcjk.c: Minor updates due to the above three changes.

+

+	* docs/TODO, docs/CHANGES: Updated.

+

+2006-02-09  Chia-I Wu  <[email protected]>

+

+	Introduce experimental autofit CJK module based on akito's autohint

+	patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.

+

+	* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,

+	src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:

+	Add CJK module based on akito's autohint patch.

+

+	* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the

+	overlap length of the segments.

+	(AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros.

+

+	* src/autofit/aflatin.h (af_latin_metrics_init_widths),

+	src/autofit/aflatin.c (af_latin_metrics_init_widths): Made

+	`FT_LOCAL'.

+	Use the character given by the caller.

+	(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale

+2006-01-31  Werner Lemberg  <[email protected]>

+

+	Implement new, simplified module selection.  With GNU make it is now

+	sufficient to modify a single file, `modules.cfg', to control the

+	inclusion of modules and base extension files.

+

+	This change also fixes the creation of ftmodule.h; it now depends on

+	`modules.cfg' and thus is rebuilt only if necessary.

+

+	Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the

+	default location.

+

+	* modules.cfg: New file.

+

+	* builds/freetype.mk: Don't include `modules.mk'.

+	Include all `rules.mk' files as specified in `modules.cfg'.

+	(FTOPTION_FLAG, FTOPTION_H): New variables.

+	(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.

+	Add FTOPTION_FLAG.

+	(make_module_list, clean_module_list): Replace targets

+	with...

+	(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New

+	variables.  Reason for the change is that it is not possible to have

+	a phony prerequisite which is run only if the target file must be

+	rebuilt (phony prerequisites act like subroutines and are *always*

+	executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is

+	changed.

+	Update all callers.

+	($FTMODULE_H)): Rule to create `ftmodule.h', depending on

+	`modules.cfg'.

+

+	* builds/toplevel.mk: Rewrite and simplify module handling.

+	(MODULES_CFG, FTMODULE_H): New variables.

+	Include MODULES_CFG.

+	(MODULES): New variable to include all `module.mk' and `rules.mk'

+

+	* Makefile (USE_MODULES): Remove.  Update all users.

+	(OBJ_DIR): Define it here.

+

+	* src/*/module.mk: Change

+

+	    make_module_list: foo

+	    foo: ...

+

+	to

+

+	    FTMODULE_H_COMMANDS += FOO

+	    define FOO

+	    ...

+	    endef

+

+	in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

+

+	* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

+

+	* builds/unix/detect.mk (setup): Always execute `configure' script.

+	(have_mk): Rename to...

+	(have_Makefile): This.

+	Don't use `strip' function.

+

+	* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is

+	defined.

+	(have_mk): Don't use `strip' function.

+	Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test

+	accordingly).

+

+	* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

+

+	* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,

+	builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define

+	BUILD_DIR but DEVEL_DIR for development header files.

+	development header files.

+	Don't define PLATFORM.

+

+	* configure: Copy `modules.cfg' to builddir if builddir != srcdir.

+	Update snippet taken from autoconf's m4sh.m4 to current CVS version.

+	Be more verbose.

+

+	* include/freetype/config/ftmodule.h: Add comments -- this file is

+	no longer used if FreeType is built with GNU make.

+

+	* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,

+	docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.

+	Other minor updates.

+

+	* modules.txt: Removed.  Contents included in `modules.cfg'.

+

+

+	* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,

+

+	* Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid'

+	and `otvalid' from the list of modules that are linked statically

+	to a given FreeType library.  Functionality has been moved to the

+

+	Note also that current Make-based build system still compiles the

+	modules though.

+

+	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro

+	which controls the definitions of the memory management functions to

+	avoid warnings with recent versions of GCC.  This macro is only here

+	to be disabled, in case we detect problems with the new scheme.

+

+	NOTE: Disable macro to use the memory debugger -- this will be fixed

+	      later!

+

+	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,

+	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,

+	FT_Request_Metrics): New base functions to set the font metrics.  They

+	were part of FT_Select_Size/FT_Request_Size and are made independent

+	functions so that metrics are not set again and again.

+

+	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set

+	only when driver's size_select/size_request is NULL.  That is, drivers

+	some fonts.

+

+	* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c

+	(tt_size_request): Set the font metrics.

+

+2006-01-20  David Turner  <[email protected]>

+

+	Change the implementation of the LIGHT hinting mode to completely

+	disable horizontal hinting.  This is an experimental effort to

+	integrate David Chester's latest patch without affecting the other

+	hinting modes as well.

+

+	Note that this doesn't force auto-hinting for all fonts, however.

+

+	* src/autofit/afhints.c (af_glyph_hints_reload): Don't set

+	(af_glyph_hints_rescale): Here.

+

+	* src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal

+

+

+	* Jamfile: Small fix to ensure that ftexport.sym is placed into the

+	same location as other generated objects (i.e., within the `objs'

+	directory of the current directory).

+

+

+	Add support for an embedded `BDF ' table within SFNT-based bitmap

+	font files.  This is used to store atoms & properties from the

+	original BDF fonts that were used to generate the font file.

+

+	The feature is controlled by TT_CONFIG_OPTION_BDF within

+	`ftoption.h' and is used to implement FT_Get_BDF_Property for these

+	font files.

+

+	At the moment, this is still experimental, the BDF table format

+	isn't cast into stone yet.

+

+

+2005-12-06  Chia-I Wu  <[email protected]>

+

+2005-11-29  Chia-I Wu  <[email protected]>

+	(tt_cmap4_init): Updated accordingly.

+	(tt_cmap4_next): Updated accordingly.

+	Take care of overlapping segments.

+	(tt_cmap4_validate): Make sure the subtable is large enough.

+	Do not check glyph_ids because some fonts set the length wrongly.

+	Also, if all segments have offset 0, glyph_ids is always invalid.

+	It does not cause any problem so far only because the check misses

+	equality.

+	Distinguish between unsorted and overlapping segments.

+	(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions

+	to do `charcode => glyph index' by linear/binary search.

+	(tt_cmap4_char_index, tt_cmap4_char_next): Use

+	tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.

+	* builds/amiga/smakefile: Adjusted the compiler options

+	to the current sources, now really builds the gxvalid, gzip

+	and psnames modules.

+

+	* builds/amiga/src/base/ftsystem.c: The assumed Seek() position

+	in the file cache was off by one byte which could cause false

+	errors in font files.

+	* src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a

+	font to have no `head' table if tables `SING' and `META' are

+	present; this is to support `SING Glyphlet'.

+

+	`SING Glyphlet' is an extension to OpenType developed by Adobe

+	primarily to facilitate adding supplemental glyphs to an OpenType

+	font (with emphasis on, but not necessarily limited to, gaiji to a

+	CJK font).  A SING Glyphlet Font is an OpenType font that contains

+	the outline(s), either in a `glyf' or `CFF' table, for a glyph;

+	`cmap', `BASE', and `GSUB' tables are present with the same format

+	and functionality as a regular OpenType font; there are no `name',

+	`head', `OS/2', and `post' tables; there are two new tables, `SING'

+	which contains details about the glyphlet, and `META' which contains

+	metadata.

+

+	Further information on the SING Glyphlet format can be found at:

+

+	  https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf

+

+	* include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for

+	the OpenType tables `SING' and `META'.  These two tables are used in

+	SING Glyphlet Format fonts.

+	    units.

+	  . As we use the glyph's cbox to calculate the top bearing now

+

+	Really fix Savannah bug #28678 (part 2).

+

+	Since we consider `sbw' for the horizontal direction only, we still have

+	to synthesize vertical metrics if the user wants to use the vertical

+	writing direction.

+

+	* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c

+	(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):

+	Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is

+	set.

+

+2010-02-10  Ken Sharp  <[email protected]>

+

+	Really fix Savannah bug #28678 (part 1).

+

+	After long discussion, we now consider the character width vector

+	(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*

+	direction only.  For example, if you are using the horizontal

+	writing direction, you get the horizontal and vertical components of

+	the advance width for this direction.  Note that OpenType and CFF fonts

+	don't have such a vertical component; instead, the GPOS table can be

+	used to generate two-dimensional advance widths (but this isn't

+	handled by FreeType).

+

+	* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add

+	`advance_v' field to hold the vertical component of the advance

+	value.

+

+	* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c

+	(cff_slot_load), src/type1/t1gload.c

+	(T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c

+	(cid_load_glyph): Use it.

+

+	New parameters for FT_Open_Face() to ignore preferred family names.

+

+2010-01-11  Kwang Yul Seo  <[email protected]>

+

+	Provide inline assembly code for RVCT compiler.

+	This is Savannah patch #7059.

+

+	* include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,

+	FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.

+

+2010-01-08  Ken Sharp  <[email protected]>

+

+	Fix Savannah bug #28521.

+

+	Issue #28226 involved a work-around for a font which used the

+	`setcurrentpoint' operator in an invalid way; this operator is only

+	supposed to be used with the result of OtherSubrs, and the font used

+	it directly.  The supplied patch removed the block of code which

+	checked this usage entirely.

+

+	This turns out to be a Bad Thing.  If `setcurrentpoint' is being

+	used correctly it should reset the flex flag in the decoder.  If we

+	don't do this then the flag never gets reset and we omit any further

+	contours from the glyph (at least until we close the path or

+	similar).

+

+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)

+	<op_setcurrentpoint>: Handle `flex_state' correctly.

+

+2010-01-05  Werner Lemberg  <[email protected]>

+

+	Apply reports from clang static analyzer.

+

+	* src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c

+	(FT_Stroker_ParseOutline), src/base/ftsynth.c

+	(FT_GlyphSlot_Embolden): Remove dead code.

+

+	* src/base/ftpatent.c (_tt_check_patents_in_table): Initialize

+	`offset_i' and `length_i'.

+

+2010-01-05  Ralph Giles  <[email protected]>

+

+	Enable the incremental font interface by default.

+

+	Ghostscript requires the incremental font interface for handling

+	some Postscript documents.  It is moving to using FreeType as its

+	primary renderer; supporting this in the default build makes it

+	Ghostscript to be linked against the system FreeType when one is

+	available.

+

+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):

+	Uncomment.

+

+2010-01-05  Werner Lemberg  <[email protected]>

+

+	Fix Savannah bug #28395.

+

+	* src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c

+	(T1_Load_Glyph): Don't check `num_glyphs' if incremental interface

+	is used.

+

+2010-01-05  Ken Sharp  <[email protected]>

+

+	Make Type 1 `seac' operator work with incremental interface.

+	This fixes Savannah bug #28480.

+

+	* src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'

+	if incremental interface is used.

+

+2010-01-04  Ken Sharp  <[email protected]>

+

+	Make incremental interface work with TrueType fonts.

+	This fixes Savannah bug #28478.

+

+	* src/truetype/ttgload.c (load_truetype_glyph): Don't check

+	`glyf_offset' if incremental interface is used.

+

+2009-12-31  Lars Abrahamsson  <[email protected]>

+

+	Make compilation with FT_CONFIG_OPTION_PIC work again.

+

+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:

+	Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.

+

+	* src/base/ftinit.c (ft_destroy_default_module_classes,

+	ft_create_default_module_classes): Use proper casts (needed for C++

+	compilation).

+

+	* src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.

+

+2009-12-22  Marc Kleine-Budde  <[email protected]>

+

+	Make freetype-config aware of $SYSROOT.

+	This is Savannah patch #7040.

+

+	* builds/unix/freetype-config.in: Decorate with ${SYSROOT} where

+	appropriate.

+

+2009-12-20  Werner Lemberg  <[email protected]>

+

+	Fix compiler warning.

+	Reported by Sean.

+

+	* src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty

+	source files; however, some compilers warn about an unused variable

+	declaration.  This is now replaced with a typedef.

+

+2009-12-18  Werner Lemberg  <[email protected]>

+

+	Fix Savannah bug #28320.

+

+	There exist corrupt, subsetted fonts (embedded in PDF files) which

+	contain a private dict that ends with an unterminated floating point

+	number (no operator following).  We now ignore this error (as

+	acrobat does).

+

+	* src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for

+	unterminated floating point numbers.

+

+2009-12-16  Werner Lemberg  <[email protected]>

+

+	Really fix compiler warnings.

+	Reported by Sean.

+

+	* src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS,

+	GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.

+

+2009-12-16  suzuki toshiya  <[email protected]>

+

+	Improve configure.raw to copy some options from CFLAGS to LDFLAGS.

+	The linker of Mac OS X 10.6 is sensitive to the architecture.  If

+	the architectures are specified explicitly for the C compiler, the

+	linker requires the architecture specifications too.

+

+	* builds/unix/configure.raw: Replace `-isysroot' option parser by

+	more generic argument parser.

+

+2009-12-15  Werner Lemberg  <[email protected]>

+

+	Fix compiler warnings.

+	Reported by Sean.

+

+	* src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data

+	type.

+

+2009-12-14  Ken Sharp  <[email protected]>

+

+	Ignore invalid `setcurrentpoint' operations in Type 1 fonts.

+	This fixes Savannah bug #28226.

+

+	At least two wild PostScript files of unknown provenance contain

+	Type 1 fonts, apparently converted from TrueType fonts in earlier

+	PDF versions of the files, which use the `setcurrentpoint' operator

+	inappropriately.

+

+	FreeType currently throws an error in this case, but Ghostscript and

+	Adobe Distiller both accept the fonts and ignore the problem.  This

+	commit #ifdefs out the check so PostScript interpreters using

+	FreeType can render these files.

+

+	The specification says `setcurrentpoint' should only be used to set

+	the point after a `Subr' call, but these fonts use it to set the

+	initial point to (0,0).  Unnecessarily so, as they correctly use an

+	`hsbw' operation which implicitly sets the initial point.

+

+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)

+	<op_setcurrentpoint>: Comment out code.

+

+2009-12-14  Bram Tassyns  <[email protected]>

+

+	Fix parsing of /CIDFontVersion.

+	This fixes Savannah bug #28287.

+

+	* src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in

+	t1tables.h) is of type FT_Fixed.

+

+2009-12-14  Werner Lemberg  <[email protected]>

+

+	Trace glyph index in CID module.

+	Suggested in Savannah patch #7023.

+

+	* src/cid/cidgload.c (cid_load_glyph): Add tracing message.

+

+2009-12-03  Werner Lemberg  <[email protected]>

+

+	Fix compiler warnings.

+

+	* src/truetype/ttgload.c (tt_get_metrics): Put `Exit' label into the

+	proper preprocessor conditional.

+	* src/pfr/pfrobjs.c (pfr_slot_load): Pacify gcc.

+

+2009-11-25  John Tytgat  <[email protected]>

+

+	Better handling of start of `eexec' section.

+	This fixes Savannah bug #28090.

+

+	* src/type1/t1parse.c (T1_Get_Private_Dict): Skip all whitespace

+	characters before start of `eexec' section.

+

+

+	Fix Savannah bug #27742.

+

+	[BDF] Modify hash API to take size_t value instead of void *.

+

+	The hash API in BDF driver is designed to be generic, it takes

+	void * typed data.  But BDF driver always gives an unsigned long

+	integer (the index to a property).  To reduce non-essential

+	casts from unsigned long to void* and from void* to unsigned

+	long, the hash API is changed to take size_t integer.

+	on LLP64 platform is reported by NightStrike from MinGW-Win64

+

+	Improve vertical metrics calculation (Savannah bug #27364).

+

+	The calculation of `vertBearingX' is not defined in the OTF font

+	spec so FreeType does a `best effort' attempt.  However, this value

+	is defined in the PDF and PostScript specs, and that algorithm is

+	better than the one FreeType currently uses:

+

+	  FreeType: Use the middle of the bounding box as the X coordinate

+	            of the vertical origin.

+

+	  Adobe PDF spec: Use the middle of the horizontal advance vector as

+	                  the X coordinate of the vertical origin.

+

+	FreeType's algorithm goes wrong if you have a really small glyph

+	(like the full-width, circle-like dot at the end of the sentence, as

+	used in CJK scripts) with large bearings.  With the FreeType

+	algorithm this dot gets centered on the baseline; with the PDF

+	algorithm it gets the correct location (in the top right).  Note

+	that this is a serious issue, it's like printing the dot at the end

+	of a Roman sentence at the center of the textline instead of on the

+	baseline like it should. So i believe the PDF spec's algorithm

+	should be used in FreeType as well.

+

+	The `vertBearingY' value for such small glyphs is also very strange

+	if no `vmtx' information is present, since the height of the bbox is

+	not representable for the height of the glyph visually (the

+	whitespace up to the baseline is part of the glyph).  The fix also

+	includes some code for a better estimate of `vertBearingY'.

+

+	* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'

+	is now calculated as described by the Adobe PDF Spec.  Estimate for

+	`vertBearingY' now works better for small glyphs completely above or

+	below the baseline into account.

+

+	* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now

+	calculated as described by the Adobe PDF Spec.  Vertical metrics

+	information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS

+	was not defined.

+

+	* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is

+	now calculated as described by the Adobe PDF Spec.

+

+	Use 16.16 format while parsing Type 1 charstrings.

+	This fixes Savannah bug #26867.

+

+	Previously, only integers have been used which can lead to serious

+	rounding errors.

+

+	However, fractional values are only used internally; after the

+	charstrings (of either Type 1 or 2) have been processed, the

+	resulting coordinates get rounded to integers currently -- before

+	applying scaling.  This should be fixed; at the same time a new load

+	flag should be introduced, to be used in combination with

+	FT_LOAD_NO_SCALE, which indicates that font units are returned in

+	16.16 format.  Similarly, the incremental interface should be

+	extended to allow fractional values for metrics.

+2009-06-18  Werner Lemberg  <[email protected]>

+

+	Fix B/W rasterization of subglyphs with different drop-out modes.

+

+	Normally, the SCANMODE instruction (if present) to set the drop-out

+	mode in a TrueType font is located in the `prep' table only and thus

+	valid for all glyphs.  However, there are fonts like `pala.ttf'

+	which additionally contain this instruction in the hinting code of

+	some glyphs (but not all).  As a result it can happen that a

+	composite glyph needs multiple drop-out modes for its subglyphs

+	since the rendering state gets reset for each subglyph.

+

+	FreeType collects the hinted outlines from all subglyphs, then it

+	sends the data to the rasterizer.  It also sends the drop-out mode

+	-- after hinting has been applied -- and here is the error: It sends

+	the drop-out mode of the last subglyph only; drop-out modes of all

+	other subglyphs are lost.

+

+	This patch fixes the problem; it adds a second, alternative

+	mechanism to pass the drop-out mode: For each contour, the

+	rasterizer now checks the first `tags' array element.  If bit 2 is

+	set, bits 5-7 contain the contour's drop-out mode, overriding the

+	global drop-out mode.

+

+	* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.

+

+	* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in

+	`tags[0]'.

+

+	* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):

+	Use bits 3-5 instead of 0-2.

+	(New_Profile): Set the drop-out mode in the profile's `flags' field.

+	(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if

+	necessary.

+	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,

+	Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out

+	mode.

+

+2009-06-16  Werner Lemberg  <[email protected]>

+

+	Improve scan conversion rules 4 and 6.

+

+	Two new constraints are introduced to better identify a `stub' -- a

+	concept which is only vaguely described in the OpenType

+	specification.  The old code was too rigorous and suppressed more

+	pixel than it should.

+

+	  . The intersection of the two profiles with the scanline is less

+	    than a half pixel.  Code related to this was already present in

+	    the sources but has been commented out.

+

+	  . The endpoint of the original contour forming a profile has a

+	    distance (`overshoot') less than half a pixel to the scanline.

+

+	Note that the two additional conditions fix almost all differences

+	to the Windows rasterizer, but some problematic cases remain.

+

+	* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New

+	macros for the `flags' field in the `TProfile' structure.

+	(IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.

+	(New_Profile, End_Profile): Pass overshoot flag as an argument and

+	set it accordingly.

+	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new

+	constraints.

+	Increase precision for B/W rasterizer.

+

+	* src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.

+

+2009-03-09  Alexey Kryukov  <[email protected]>

+

+	Fix handling of EBDT formats 8 and 9 (part 2).

+

+	This patch fixes the following problems in ttsbit0.c:

+

+	. Bitmaps for compound glyphs were never allocated.

+

+	. `SBitDecoder' refused to load metrics if some other metrics have

+	  already been loaded.  This condition certainly makes no sense for

+	  recursive calls, so I've just disabled it.  Another possibility

+	  would be resetting `decoder->metrics_loaded' to false before

+	  loading each composite component.  However, we must restore the

+	  original metrics after finishing the recursion; otherwise we can

+	  get a misaligned glyph.

+

+	. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',

+	  causing some glyph components to be shifted too far to the right

+	  (especially noticeable for small sizes).

+

+	Note that support for grayscale bitmaps (not necessarily compound) is

+	completely broken in ttsbit0.c.

+

+	* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.

+	(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case

+	of `h == height'.

+	(tt_sbit_decoder_load_compound): Reset metrics after loading

+	components.

+	Allocate bitmap.

+

+	FT_USE_MODULE declares things as:

+

+	  extern const FT_Module_Class

+

+	(or similar for C++).  However, the actual types of the variables

+	being declared are often different, e.g., FT_Driver_ClassRec or

+	FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

+

+	This works with most C compilers (since those structs begin with an

+	FT_Module_Class struct), but technically it's undefined behavior.

+

+	To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7

+	paragraph 2:

+

+	  All declarations that refer to the same object or function shall

+	  have compatible type; otherwise, the behavior is undefined.

+

+	(And they are not compatible types.)

+

+	Most C compilers don't reject (or even detect!) code which has this

+	issue, but the GCC LTO development branch compiler does.  (It

+	outputs the types of the objects while generating .o files, along

+	with a bunch of other information, then compares them when doing the

+	final link-time code generation pass.)

+

+	Patch from Savannah bug #25133.

+

+	Generalize the concept of `tricky' fonts by introducing

+	engine is necessary for correct rendering.

+

+	At the same time, slightly modify the behaviour of tricky fonts:

+	FT_LOAD_NO_HINTING is now ignored.  To really force raw loading

+	of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and

+	FT_LOAD_NO_AUTOHINT must be used.

+

+	Finally, tricky TrueType fonts always use the bytecode interpreter

+	even if the patented code is used.

+2008-10-09  suzuki toshiya  <[email protected]>

+

+	Fix Savannah bug #24468.

+

+	According to include/freetype/internal/ftobjs.h, the appropriate

+	type to interchange single character codepoint is FT_UInt32. It

+	should be distinguished from FT_UInt which can be 16bit integer.

+

+	(open_face_PS_from_sfnt_stream): New function.  It checks whether

+	the stream is sfnt-wrapped Type1 PS font or sfnt-wrapped CID-keyed

+	font, then try to open a face for given face_index.

+	(Mac_Read_sfnt_Resource): Replace the combination of

+	`ft_lookup_PS_in_sfnt' and `open_face_from_buffer' by

+	`open_face_PS_from_sfnt_stream'.

+	macro __APPLE__ by themselves.

+	* builds/unix/ftconfig.in: Ditto.

+	* builds/vms/ftconfig.h: Ditto.

+	* src/base/ftbase.c: Use FT_MACINTOSH instead of __APPLE__, to

+

+2008-10-02  suzuki toshiya  <[email protected]>

+

+	* src/base/ftbase.h: New file to declare the private utility

+	`ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to

+	share between ftobjs.c and ftmac.c.

+

+	* src/base/rule.mk: Add ftbase.h.

+

+	* src/base/ftobjs.c: Include ftbase.h.

+	support is enabled.

+	(new_memory_stream): Ditto.

+	(open_face_from_buffer): Build on any platform when old MacOS font

+	support is enabled.  The counting of the face in a font file is

+

+	* src/base/ftmac.c: Include ftbase.h.

+	Reported by Graham Asher.

+

+2008-09-30  suzuki toshiya  <[email protected]>

+

+	* src/base/rules.mk: Add conditional source to BASE_SRC, for `make

+	multi' on Mac OS X.  If the macro $(ftmac_c) is defined,

+	$(BASE_DIR)/$(ftmac_c) is added to BASE_SRC.  In a normal build, the

+	lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes

+	ftmac.c.

+	* builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).

+	* builds/unix/configure.raw: Add procedure to set up appropriate

+	value of $(ftmac_c) with the consideration of the availability of

+	Carbon framework.

+2008-09-30  suzuki toshiya  <[email protected]>

+

+	* src/base/Jamfile: Add target for multi build by jam on Mac OS X.

+

+	* src/cff/cffgload.c (CFF_Operator, cff_argument_counts,

+	jam.

+

+2008-09-20  Werner Lemberg  <[email protected]>

+

+	* src/smooth/ftgrays.c (gray_find_cell): Fix threshold.  The values

+	passed to this function are already `normalized'.  Problem reported

+

+	* docs/CHANGES: Document it.

+

+2008-09-20  Werner Lemberg  <[email protected]>

+

+	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in

+	sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.

+	`open_face_from_buffer' frees the passed buffer if it cannot open a

+	face from the buffer, so the caller must not free it.

+

+2008-09-19  suzuki toshiya  <[email protected]>

+

+	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support

+	for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.

+	(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '

+	table in sfnt table directory.  It is used before loading TrueType

+	font driver.

+

+	* docs/CHANGES: Add note about the current status of sfnt-wrapped

+	Type1 and sfnt-wrapped CID-keyed font support.

+

+2008-09-18  Werner Lemberg  <[email protected]>

+

+	* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for

+	orthogonality (ft_free and ft_sfree could belong to different memory

+	pools).  This fixes Savannah bug #24297.

+

+2008-09-18  suzuki toshiya  <[email protected]>

+

+	* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined

+	of default values.

+

+2008-09-15  Werner Lemberg  <[email protected]>

+

+	* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'

+	and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to

+	prevent unconditional definition.  This fixes Savannah bug #24241.

+

+	* src/psnames/pstables.h: Regenerated.

+

+2008-09-13  Werner Lemberg  <[email protected]>

+

+	* autogen.sh, builds/unix/configure.raw,

+

+2008-09-11  suzuki toshiya  <[email protected]>

+

+	* builds/unix/ftconfig.in: Duplicate the cpp computation of

+	FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.

+	(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp

+	computation is disabled and the statically configured sizes are

+	used.  This fixes Savannah bug #21250.

+

+	* builds/unix/configure.raw: Add the checks to compare the cpp

+	computation results of the bit length of int and long versus the

+	sizes detected by running `configure'.  If the results are

+	different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the

+	results.

+	New option --{enable|disable}-biarch-config is added to define or

+	undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.

+

+2008-09-05  suzuki toshiya  <[email protected]>

+

+	* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or

+	ApplicationServices framework is missing.  Although this value is not

+	used in building of FreeType2, it is written in `freetype2.pc' and

+	`freetype-config'.

+

+2008-09-01  David Turner  <[email protected]>

+

+	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap

+	index to mean `use default cached FT_Face's charmap'.  This fixes

+	Savannah bug #22625.

+	* include/freetype/ftcache.h: Document it.

+

+

+	Make FT_MulFix an inlined function.  This is done to speed up

+	FreeType a little (on x86 3% when loading+hinting, 10% when

+	rendering, ARM savings are more important though).  Disable this by

+	undefining FT_CONFIG_OPTION_INLINE_MULFIX.

+

+	Use of assembler code can now be controlled with

+	FT_CONFIG_OPTION_NO_ASSEMBLER.

+

+	* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in

+	which is defined to the platform-specific assembler implementation

+	of FT_MulFix.

+	[FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]

+

+	* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and

+	FT_MULFIX_INLINED.

+

+

+	Add a new header named FT_ADVANCES_H declaring some new APIs to

+	extract the advances of one or more glyphs without necessarily

+	loading their outlines.  Also provide `fast loaders' for the

+	TrueType, Type1, and CFF font drivers (more to come later).

+

+	* src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.

+

+	* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.

+	Update callers.

+	* src/truetype/ttgload.h: Declare them.

+

+	* src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New

+	function.

+

+

+	Add checks for minimum version of the `autotools' stuff.

+

+	* autogen.sh: Implement it.

+	(get_major_version, get_minor_version, get_patch_version,

+	compare_to_minimum_version, check_tool_version): New auxiliary

+	functions.

+

+

+2008-08-28  Werner Lemberg  <[email protected]>

+

+	* src/type1/t1load.c (parse_encoding): Protect against infinite

+	#24119.

+

+2008-08-19  suzuki toshiya  <[email protected]>

+

+	* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,

+	even if passed library or arguments are invalid.  This fixes a bug

+	that an uninitialized stream is freed when an invalid library handle

+	is passed.  Originally proposed by Mike Fabian, 2008/08/18 on

+	freetype-devel.

+	(FT_Open_Face): Ditto (stream).

+	(load_face_in_embedded_rfork): Ditto (stream2).

+

+2008-08-18  suzuki toshiya  <[email protected]>

+

+	* src/base/ftmac.c: Add a fallback to guess the availability of the

+	(e.g., a build with Jam).

+	* builds/mac/ftmac.c: Ditto.

+	* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0

+	explicitly, even if `ResourceIndex' is unavailable.

+

+2008-08-18  suzuki toshiya  <[email protected]>

+

+	* builds/unix/configure.raw: In checking of Mac OS X features,

+	all-in-one header file `Carbon.h' is replaced by the minimum

+	header file `CoreServices.h', similar to current src/base/ftmac.c.

+

+2008-08-18  suzuki toshiya  <[email protected]>

+

+	* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of

+	sub-header when its code_count is 0.  Many Japanese Dynalab fonts

+	include such an empty sub-header (code_count == 0, first_code == 0

+	delta == 0, but offset != 0) as the second sub-header in SJIS cmap.

+

+2008-08-04  Werner Lemberg  <[email protected]>

+

+	* src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes

+	Savannah bug #23995.

+

+	* src/cid/cidload.c (parse_expansion_factor): New callback function.

+	(cid_field_records): Use it for `ExpansionFactor'.

+	* src/cod/cidtoken.h: Handle `ForceBold' keyword.

+	Don't handle `ExpansionFactor'.

+

+2008-08-04  Bram Tassyns  <[email protected]>

+

+	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which

+	resulted in incorrect scaling.  This fixes Savannah bug #23973.

+

+2008-08-04  Werner Lemberg  <[email protected]>

+

+	Be more tolerant w.r.t. invalid entries in SFNT table directory.

+

+	* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and

+	adjust table count.

+	Add more trace messages.

+	(tt_face_load_font_dir): Updated.

+

+2008-07-30  Werner Lemberg  <[email protected]>

+

+	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer

+	assume that the first argument on the stack is the bottom-most

+	element.  Two reasons:

+

+	  o According to people from Adobe it is missing in the Type 2

+	    specification that pushing of additional, superfluous arguments

+	    on the stack is prohibited.

+

+	  o Acroread in general handles fonts differently, namely by popping

+	    the number of arguments needed for a particular operand (as a PS

+	    interpreter would do).  In case of buggy fonts this causes a

+	    different interpretation which of the elements on the stack are

+	    superfluous and which not.

+

+	Since there are CFF subfonts (embedded in PDFs) which rely on

+	Acroread's behaviour, FreeType now does the same.

+

+2008-07-27  Werner Lemberg  <[email protected]>

+

+	Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This

+	fixes Savannah bug #23940.

+

+	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...

+	(EXTRA_GLYPH_LIST_SIZE): This.

+	Increase by 2.

+	(ft_wgl_extra_unicodes): Rename to...

+	(ft_extra_glyph_unicodes): This.

+	Add two code values.

+	(ft_wgl_extra_glyph_names): Rename to...

+	(ft_extra_glyph_names): This.

+	Add two glyphs.

+	(ft_wgl_extra_glyph_name_offsets): Rename to...

+	(ft_extra_glyph_name_offsets): This.

+	Add two offsets.

+

+	(ps_check_wgl_name, ps_check_wgl_unicode): Rename to...

+	(ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.

+	Updated.

+	(ps_unicodes_init): Updated.

+

+2008-07-26  Werner Lemberg  <[email protected]>

+

+	* src/cff/cffgload.c (cff_decoder_prepare,

+	cff_decoder_parse_charstrings): Improve debug output.

+

+2008-07-22  Martin McBride  <[email protected]>

+

+	* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,

+	tt_cmap4_char_map_binary): Handle fonts which treat the last segment

+	specially.  According to the specification, such fonts would be

+	invalid but acroread accepts them.

+

+2008-07-16  Jon Foster  <[email protected]>

+

+	* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

+

+	* src/base/ftcalc.c (FT_MulFix): Fix portability issue.

+

+	* src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:

+	Fix compiler warning.

+

+2008-07-16  Werner Lemberg  <[email protected]>

+

+	Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.

+

+	* src/cff/cffload.c (cff_font_load): Pass `pure_cff'.

+	Invert sids table only if `pure_cff' is set.

+	* src/cff/cffload.h: Updated.

+

+	* src/cff/cffobjs.c (cff_face_init): Updated.

+	Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.

+

+	* docs/CHANGES: Updated.

+

+2008-07-09  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts

+	where num_locations < num_glyphs.  Problem reported by Ding Li.

+

+2008-07-05  Werner Lemberg  <[email protected]>

+

+	Since FreeType uses `$(value ...)', we now need GNU make 3.80 or

+	newer.  This fixes Savannah bug #23648.

+

+	* configure: zsh doesn't like ${1+"$@"}.

+	Update needed GNU make version.

+	* builds/toplevel.mk: Check for `$(eval ...)'.

+	* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document

+	it.

+

+2008-07-04  Werner Lemberg  <[email protected]>

+

+	* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one

+	pixel, only check for dropouts if neither start nor end point lies

+	on a pixel center.  This fixes Savannah bug #23762.

+

+2008-06-29  Werner Lemberg  <[email protected]>

+

+	* Version 2.3.7 released.

+	=========================

+

+

+	Tag sources with `VER-2-3-7'.

+

+	* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump

+	version number to 2.3.7.

+

+	* README, Jamfile (RefDoc), builds/win32/visualc/index.html,

+	builds/win32/visualc/freetype.dsp,

+	builds/win32/visualc/freetype.vcproj,

+	builds/win32/visualce/index.html,

+	builds/win32/visualce/freetype.dsp,

+	builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.

+

+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.

+

+	* builds/unix/configure.raw (version_info): Set to 9:18:3.

+

+	* docs/release: Updated.

+

+2008-06-28  Werner Lemberg  <[email protected]>

+

+	* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...

+	* src/ftcalc.c: Here.  This fixes Savannah bug #23729.

+

+2008-06-27  Werner Lemberg  <[email protected]>

+

+	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,

+	Horizontal_Gray_Sweep_Drop): Test for intersections which

+	degenerate to a single point can be ignored; this has been confirmed

+	by Greg Hitchcock from Microsoft.  (This was commented out code.)

+

+2008-06-26  Werner Lemberg  <[email protected]>

+

+	Improve navigation in API reference.

+

+	* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...

+	(html_header_6): This.

+	(html_header_3, html_header_3i, html_header_4, html_header_5,

+	html_header_5t): New strings.

+	(toc_footer_start, toc_footer_end): New strings.

+	(HtmlFormatter::html_header): Updated.

+	(HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):

+	New strings.

+	(HtmlFormatter::index_enter): Use `html_index_header'.

+	(HtmlFormatter::index_exit): Print `html_footer'.

+	(HtmlFormatter::toc_enter): Use `html_toc_header'.

+	(HtmlFormatter::toc_exit): Print proper footer.

+

+	Convert ~ to non-breakable space.

+

+	* src/tools/docmaker/tohtml.py (make_html_para): Implement it.

+	Update header files accordingly.

+

+2008-06-24  suzuki toshiya  <[email protected]>

+

+	* builds/unix/configure.raw: Check type `ResourceIndex' explicitly

+	and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5

+	bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without

+	ResourceIndex type definition.  The macro does not inform the type

+	availability.

+	* src/base/ftmac.c: More parentheses are inserted to clarify the

+	conditionals to disable legacy APIs in `10.5 and later' cases.  If

+	HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.

+

+2008-06-24  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering

+	mode.

+

+	* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,

+	Draw_Sweep): No-dropout mode is value 2, not value 0.

+	(Draw_Sweep): Really skip dropout handling for no-dropout mode.

+

+2008-06-24  Werner Lemberg  <[email protected]>

+

+	* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour

+	if it consists of one point only.  Based on a patch from Savannah

+	bug #23683 (from John Tytgat).

+

+2008-06-22  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff

+	with IS_HINTED.

+

+	* docs/CHANGES: Updated.

+

+2008-06-22  suzuki toshiya  <[email protected]>

+

+	* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option

+	but LDFLAGS does not, import it to LDFLAGS.  The option is used to

+	specify non-default SDK on Mac OS X (e.g., universal binary SDK for

+	Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137

+	recommends to add the option only to CFLAGS, LDFLAGS should include

+	it because libfreetype.la is built with -no-undefined.  This fixes a

+	bug reported by Ryan Schmidt in MacPorts,

+	https://trac.macports.org/ticket/15331.

+

+2008-06-21  Werner Lemberg  <[email protected]>

+

+	Enable access to the various dropout rules of the B&W rasterizer.

+	Pass dropout rules from the TT bytecode interpreter to the

+	rasterizer.

+

+	* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,

+	FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.

+

+	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,

+	Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the

+	OpenType specification.

+	Fix mode 4 computation.

+	(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

+

+	* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion

+	mode to FT_OUTLINE_XXX flags.

+

+	* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

+

+2008-06-19  Werner Lemberg  <[email protected]>

+

+	* src/cff/cffobjs.c (cff_face_init): Compute final

+	`dict->units_per_em' value before assigning it to

+	`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are

+	scaled incorrectly if the font matrix is non-standard.  This fixes

+	Savannah bug #23630.

+

+	* docs/CHANGES: Updated.

+

+2008-06-19  Werner Lemberg  <[email protected]>

+

+	* src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix

+	from 2008-06-19.

+

+2008-06-18  Werner Lemberg  <[email protected]>

+

+	* src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.

+	Reported by Peter Weilbacher <[email protected]>.

+

+	* docs/CHANGES: Updated.

+

+2008-06-15  George Williams  <[email protected]>

+

+	* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set

+	`valid->extra2' to 1.  This is undocumented in the OpenType 1.5

+	specification.

+

+2008-06-15  Werner Lemberg  <[email protected]>

+

+	* src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly

+	from clobbering.  Patch from Savannah bug report #23556.

+

+	* docs/CHANGES: Document it.

+

+2008-06-10  Werner Lemberg  <[email protected]>

+

+	* autogen.sh: Add option `--install' to libtoolize.

+

+2008-06-10  Werner Lemberg  <[email protected]>

+

+	* Version 2.3.6 released.

+	=========================

+

+	* src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.

+

+2008-06-10  Werner Lemberg  <[email protected]>

+

+	* src/base/ftobjs.c (open_face): Check `clazz->init_face' and

+	`clazz->done_face'.

+

+2008-06-09  VaDiM  <[email protected]>

+

+	Support debugging on WinCE.  From Savannah patch #6536; this fixes

+	bug #23497.

+

+	* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro

+	as a replacement for OutputDebugStringA (which WinCE doesn't have).

+	Update all callers.

+	(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have

+	environment variables.

+

+2008-06-09  Werner Lemberg  <[email protected]>

+

+	* README.CVS: Updated.

+

+	* builds/unix/configure.raw, builds/unix/freetype-config.in: Updated

+	for newer versions of autoconf and friends.

+

+2008-06-08  Werner Lemberg  <[email protected]>

+

+	* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and

+	`private_len' unsigned.

+

+	* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read

+	it as such.

+	(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.

+

+

+	* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.

+

+

+	* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'

+	for sane value.

+	Fix typo.

+

+

+	* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.

+

+

+	* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check

+	`last_point'.

+

+

+	* src/sfnt/ttload.c (tt_face_load_max_profile): Limit

+	`maxTwilightPoints'.

+

+2008-06-06  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'

+	correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.

+

+2008-06-03  Werner Lemberg  <[email protected]>

+

+	* include/freetype/ftcache.h (FTC_FaceID): Change type back to

+	FT_Pointer.  Reported by Ian Britten <[email protected]>.

+

+2008-06-02  Werner Lemberg  <[email protected]>

+

+	Emit header info for defined FreeType objects in reference.

+

+	* src/tools/docmaker/content.py (re_header_macro): New regexp.

+	(ContentProcessor::__init__): Initialize new dictionary `headers'.

+	(DocBlock::__init__): Collect macro header definitions.

+

+	* src/tools/docmaker/tohtml.py (header_location_header,

+	header_location_footer): New strings.

+	(HtmlFormatter::__init__): Pass `headers' dictionary.

+	(HtmlFormatter::print_html_field): Don't emit paragraph tags.

+	(HtmlFormatter::print_html_field_list): Emit empty paragraph.

+	(HtmlFormatter::block_enter): Emit header info.

+

+2008-06-01  Werner Lemberg  <[email protected]>

+

+	* include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,

+	FT_INCREMENTAL_H): Added.

+

+2008-05-28  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/sources.py (SourceBlock::__init__): While

+	looking for markup tags, return immediately as soon a single one is

+	found.

+

+2008-05-28  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses

+	original, unscaled input values.  Confirmed by Greg Hitchcock from

+	Microsoft.

+

+2008-05-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py (block_footer_start,

+	block_footer_middle): Beautify output.

+

+2008-05-25  Werner Lemberg  <[email protected]>

+

+	* src/raster/ftraster.c (fc_black_render): Return 0 when we are

+	trying to render into a zero-width/height bitmap, not an error code.

+

+	* src/truetype/ttgload.c (load_truetype_glyph): Move initialization

+	of the graphics state for subglyphs to...

+	(TT_Hint_Glyph): This function.

+	Hinting instructions for a composite glyph apparently refer to the

+	just hinted subglyphs, not the unhinted, unscaled outline.  This

+	seems to fix Savannah bugs #20973 and (at least partially) #23310.

+

+2008-05-20  suzuki toshiya  <[email protected]>

+

+	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

+	`aface' is returned by FT_New_Face_From_FOND().  The patch was

+	proposed by an anonymous reporter of Savannah bug #23204.

+

+2008-05-18  Werner Lemberg  <[email protected]>

+

+	* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after

+	correction for pixel boundary.  Without this patch, the effect can

+	be cumulative under certain circumstances, making glyphs taller and

+	taller after each call.  This fixes Savannah bug #19976.

+

+2008-05-18  Werner Lemberg  <[email protected]>

+

+	* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

+	This fixes Savannah bug #23280.

+

+	* docs/CHANGES: Updated.

+

+2008-05-18  David Turner  <[email protected]>

+

+	* src/psnames/psmodule.c (ft_wgl_extra_unicodes,

+	ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,

+	ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make

+	declarations non-global.

+

+	* src/type1/t1load.c: Add missing comment.

+

+2008-05-17  Sam Hocevar  <samh>

+

+	* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour

+	glyphs correctly.  Patch from Savannah bug #23277.

+

+2008-05-16  Werner Lemberg  <[email protected]>

+

+	* docs/CHANGES: Updated.

+

+2008-05-16  Sergey Tolstov  <[email protected]>

+

+	Improve support for WGL4 encoded fonts.

+

+	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.

+	ft_wgl_extra_glyph_name_offsets): New arrays.

+	(ps_check_wgl_name, ps_check_wgl_unicode): New functions.

+	(ps_unicodes_init): Use them to add additional Unicode mappings.

+

+2008-05-15  Werner Lemberg  <[email protected]>

+

+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)

+	<op_closepath>: `closepath' without a path is a no-op, not an error

+	(cf. the PS reference manual).

+

+	Reported by Martin McBride.

+

+2008-05-15  Werner Lemberg  <[email protected]>

+

+	* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.

+

+2008-05-15  Werner Lemberg  <[email protected]>

+

+	* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array

+	which contains a single but empty entry.  This is technically

+	invalid (since it must end with `return'), but...

+

+	Reported by Martin McBride.

+

+2008-05-14  Werner Lemberg  <[email protected]>

+

+	Finish fix of scaling bug of CID-keyed CFF subfonts.

+

+	* include/freetype/internal/ftcalc.h, src/base/ftcalc.c

+	(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New

+	functions.

+

+	* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to

+	provide global hinting data for both the top-font and all subfonts

+	(with proper scaling).

+

+	* src/cff/cffobjs.c (cff_make_private_dict): New function, using

+	code from `cff_size_init'.

+	(cff_size_init, cff_size_done, cff_size_select, cff_size_request):

+	Use CFF_Internal and handle subfonts.

+	(cff_face_init): Handle top-dict and subfont matrices correctly;

+	apply some heuristic in case of unlikely matrix concatenation

+	results.  This has been discussed with people from Adobe (thanks

+	goes mainly to David Lemon) who confirm that the CFF specs are fuzzy

+	and not correct.

+

+	* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

+

+	* src/cff/cffgload.c (cff_builder_init): Updated.

+	(cff_decoder_prepare): Handle hints globals for subfonts.

+	Update all callers.

+	(cff_slot_load): Handling scaling of subfonts properly.

+

+	* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.

+	(cff_parse_font_matrix): Use it.

+

+	* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'

+	FT_ULong.

+

+	* docs/CHANGES: Document it.

+

+2008-05-13  Werner Lemberg  <[email protected]>

+

+	* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):

+	Handle case `face_index < 0'.

+	* docs/CHANGES: Document it.

+

+2008-05-04  Werner Lemberg  <[email protected]>

+

+	First steps to fix the scaling bug of CID-keyed CFF subfonts,

+	reported by Ding Li on 2008/03/28 on freetype-devel.

+

+	* src/base/cff/cffparse.c (power_tens): New array.

+	(cff_parse_real): Rewritten to introduce a fourth parameter which

+	returns the `scaling' of the real number so that we have no

+	precision loss.  This is not used yet.

+	Update all callers.

+	(cff_parse_fixed_thousand): Replace with...

+

+2008-05-03  Werner Lemberg  <[email protected]>

+

+	* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without

+	Savannah bug #23143.

+

+2008-04-26  Werner Lemberg  <[email protected]>

+

+

+2008-02-21  suzuki toshiya  <[email protected]>

+

+	* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name

+	synthesis.  For any face of a specified FOND, always the name for

+	the first face was used.  Except of a FOND that refers multiple

+	Type1 font files, wrong synthesized font names are not used at all,

+	so this is an invisible bug.  A few limit checks are added too.

+

+	* builds/mac/ftmac.c: Ditto.

+

+2008-02-21  suzuki toshiya  <[email protected]>

+

+	* builds/unix/configure.raw: Split compiler option to link Carbon

+	frameworks to one option for CoreServices framework and another

+

+	* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource

+	handle by its value instead of ResError(), fix provided by Deron

+	Kazmaier.  According to the Resource Manager Reference,

+	GetResource(), Get1Resource(), GetNamedResource(),

+	Get1NamedResource() and RGetResource() set noErr but return NULL

+	handle when they can not find the requested resource.  These

+	functions never return undefined values, so it is sufficient to

+	check if the handle is not NULL.

+

+	* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.

+

+2008-02-14  suzuki toshiya  <[email protected]>

+

+	* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other

+	builds/mac/ftmac.c is never included in any configuration.

+

+	* builds/unix/configure.raw: Print warning if configure is executed

+	with options to specify Carbon functionalities explicitly.

+

+	* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not

+

+	* src/truetype/ttgload.c (load_truetype_glyph): Handle the case

+

+2008-01-04  suzuki toshiya  <[email protected]>

+

+2007-12-21  suzuki toshiya  <[email protected]>

+

+	Improvement of POSIX resource-fork accessor to load unsorted

+	references in a resource.  In HelveLTMM (resource-fork PostScript

+	Type1 font bundled with Mac OS X since 10.3.x), the appearance order

+	of PFB chunks is not sorted; sorting the chunks by reference IDs is

+	required.

+

+	* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure

+	type to store a pair of reference ID and offset to the chunk.

+

+	* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to

+	sort FT_RFork_Ref by their reference IDs.

+

+	(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is

+	sorted by reference ID.

+

+2007-12-14  Werner Lemberg  <[email protected]>

+

+	* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'

+	division too early; otherwise the most significant digit(s) of the

+	final result are lost as the value is truncated to an integer.  This

+	fixes Savannah bug #21794 (where the patch has been posted too).

+

+2007-12-06  Fix  <[email protected]>

+

+	Pass options from one configure script to another as-is (not

+	expanded).  This is needed for options like

+	call to the (real) `configure' script.

+

+2007-12-06  Werner Lemberg  <[email protected]>

+

+

+2007-12-06  Werner Lemberg  <[email protected]>

+

+	There exist CFFs which contain opcodes for the Type 1 operators

+	`hsbw' and `closepath' which are both invalid in Type 2 charstrings.

+	However, it doesn't harm to support them.

+

+	* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and

+	`cff_op_closepath.'

+	(cff_argument_counts): Ditto.

+

+	(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)

+

+2007-12-06  suzuki toshiya  <[email protected]>

+

+	* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to

+	case-sensitive HFS+.

+	(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of

+

+2007-12-06  suzuki toshiya  <[email protected]>

+

+2007-11-20  suzuki toshiya  <[email protected]>

+

+	Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is

+	not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()

+	cannot mmap() the specified file and cannot seek to head of the

+	specified file, it returns NULL stream and FT_Open_New() returns the

+	error immediately.  On MacOS, most legacy MacOS fonts fall into such

+	a scenario because their data forks are zero-sized and cannot be

+	sought.  To proceed to guessing of resource fork fonts, the

+	functions for legacy MacOS font must properly handle the NULL stream

+	returned by FT_New_Stream().

+

+	* src/base/ftobjs.c (IsMacBinary): Return error

+	FT_Err_Invalid_Stream_Operation immediately when NULL stream is

+	passed.

+	(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed

+	to fallback.  Originally, legacy MacOS font is tested in the cases

+	of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)

+	or FT_Err_Unknown_File_Format (occurs when AppleSingle header or

+	.dfont header is combined).  Now the case of

+	FT_Err_Cannot_Open_Stream is included.

+

+	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,

+	skip FT_Stream_Seek(), which seeks to the head of stream, and

+	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()

+	for a NULL stream causes a Bus error on Mac OS X.

+	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream

+	immediately if passed stream is NULL.

+	(raccess_guess_apple_single): Ditto.

+

+2007-11-16  suzuki toshiya  <[email protected]>

+

+	Fix for Carbon incompatibilities since Mac OS X 10.5,

+	proposed by Sean McBride.

+

+	* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.

+

+	* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and

+	FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling

+	Carbon functions from a forked process is classified as unsafe

+	by Apple.  All Carbon-dependent functions should be deprecated.

+

+	* src/base/ftmac.c: Use essential header files

+	<CoreServices/CoreServices.h> and

+	<ApplicationServices/ApplicationServices.h> instead of

+	all-in-one header file <Carbon/Carbon.h>.

+

+	Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple

+	genuine macro PATH_MAX.

+

+	Add fallback macro for kATSOptionFlagsUnRestrictedScope which

+	is not found in Mac OS X 10.0.

+

+	Multi-character constants ('POST', 'sfnt' etc) are replaced by

+	64bit constants calculated by FT_MAKE_TAG() macro.

+

+	For the index in the segment of resource fork, new portable

+	type ResourceIndex is introduced for better compatibility.

+	This type is since Mac OS X 10.5, so it is defined as short

+	when built on older platforms.

+

+	(FT_ATSFontGetFileReference): If build target is only the systems

+	10.5 and newer, it calls Apple genuine ATSFontGetFileReference().

+

+	(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5

+	and newer or 64bit platform, because legacy type FSSpec type is

+	removed completely.

+

+	(FT_New_Face_From_FSSpec): Ditto.

+

+2007-11-01  Werner Lemberg  <[email protected]>

+

+	* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This

+	fixes Savannah bug #21485.

+

+2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>

+

+	* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver

+	can handle the font at all, then check `face_index'.  Otherwise, the

+	driver might return the wrong error code.  This fixes Savannah bug

+	#21468.

+

+2007-10-21  Werner Lemberg  <[email protected]>

+

+	* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare

+	support for bit 8 of the `fsSelection' field in the `OS/2' table.

+	MS is already using this; hopefully, this becomes part of OpenType

+	1.5.

+	Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22

+	(WWS_SUBFAMILY).

+

+2007-10-20  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.

+	Add `td.left' element to CSS.

+	(toc_section_enter): Use it.

+

+2007-10-18  David Turner  <[email protected]>

+

+	* include/freetype/freetype.h, src/base/ftobjs.c: Rename API

+	functions related to cmap type 14 support to the

+	`FT_Object_ActionName' scheme:

+

+	  FT_Get_Char_Variant_Index     -> FT_Face_GetCharVariantIndex

+	  FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault

+	  FT_Get_Variant_Selectors      -> FT_Face_GetVariantSelectors

+	  FT_Get_Variants_Of_Char       -> FT_Face_GetVariantsOfChar

+	  FT_Get_Chars_Of_Variant       -> FT_Face_GetCharsOfVariant

+

+	Update documentation accordingly.

+

+	* src/sfnt/ttcmap.c: Stronger cmap 14 validation.

+	Make the code a little more consistent with FreeType coding

+	conventions and modify the cmap14 functions that returned a newly

+	allocated array to use a persistent vector from the TT_CMap14 object

+	instead.

+

+	(TT_CMap14Rec): Provide array and auxiliary data for result.

+	(tt_cmap14_done, tt_cmap14_ensure): New functions.

+

+2007-04-02  David Turner  <[email protected]>

+

+

+

+	* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c

+	(af_loader_load_g): Disable the warper (i.e., the light hinting

+	improvements) to make a 2.3.1 bugfix release before introducing a

+

+	* docs/CHANGES: Update accordingly.

+

+2007-01-25  David Turner  <[email protected]>

+

+

+	* docs/CHANGES: Document it.

+	`modules.cfg').

+

+	* src/sfnt/ttsbit0.h: Remove.

+

+	* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.

+

+2007-01-12  David Turner  <[email protected]>

+

+	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping

+

+2007-01-10  David Turner  <[email protected]>

+

+	* all-sources: Tag all sources with VER-2-3-0-RC1 and

+	values.

+

+2007-01-08  David Turner  <[email protected]>

+	* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the

+	`gasp' table, in order to avoid potential problems with later

+	versions.

+

+	* include/freetype/config/ftheader.h (FT_GASP_H): New macro for

+	<freetype/ftgasp.h>.

+

+	* src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),

+	modules.cfg (BASE_EXTENSIONS), builds/win32/visualc/freetype.dsp,

+	builds/win32/visualc/freetype.vcproj: Add src/base/ftgasp.c to the

+

+2007-01-07  Werner Lemberg  <[email protected]>

+

+	* src/cid/cidparse.c (cid_parser_new): Improve error message for

+	Scan for `/sfnts' token.

+

+2007-01-07  Werner Lemberg  <[email protected]>

+

+2007-01-06  Werner Lemberg  <[email protected]>

+

+	* src/cff/cffload.c (cff_index_init): Remove unused variable.

+	(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.

+

+2007-01-04  David Turner  <[email protected]>

+

+	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts

+	correctly.  This fixes Savannah bug #17876.

+

+

+	Do not allocate interpreter-specific tables in memory if we are not

+	going to load glyphs with the bytecode interpreter anyway.

+

+	* src/truetype/ttgload.c (tt_loader_init): Load execution context

+	only if glyph is hinted.

+	Updated.

+	* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'

+	and `cvs_ready'.

+	Add `tt_size_ready_bytecode' declaration.

+	* src/truetype/ttobjs.c (tt_size_done_bytecode,

+	tt_size_init_bytecode, tt_size_ready_bytecode): New functions.

+	(tt_size_init): Move most code into `tt_size_init_bytecode'.

+	(tt_size_done): Move most code into `tt_size_done_bytecode'.

+	(tt_size_reset): Move some code to `tt_size_ready_bytecode'.

+

+

+	Don't extract the metrics table from the SFNT font file.  Instead,

+	reparse it on each glyph load.  The runtime difference is not

+	noticeable, and it can save a lot of heap memory when memory-mapped

+	files are not used.

+

+	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members

+	`horz_metrics_offset' and `vert_metrics_offset'.

+	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):

+	Updated.

+

+

+	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.

+

+

+	Do not load the CFF index offsets into memory, since this wastes a

+	*lot* of heap memory with large Asian CFF fonts.  There is no

+	significant performance loss.

+

+	* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.

+	* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and

+	`data_size'.

+	(CFF_CharsetRec): Add field `num_glyphs'.

+

+	* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,

+	cff_charset_cid_to_gindex): New functions.

+	(cff_new_index): Renamed to...

+	(cff_index_init): This.  Update all callers.

+	Updated -- some code has been moved to `cff_index_load_offsets'.

+	(cff_done_index): Renamed to...

+	(cff_index_done): This.  Update all callers.

+	(cff_index_get_pointers, cff_index_access_element): Updated to use

+	stream offsets.

+	(cff_charset_compute_cids): Set `num_glyphs' field.

+	(cff_encoding_load): Updated.

+

+	* src/cff/cffgload.c (cff_slot_load): Updated.

+

+2007-01-04  David Turner  <[email protected]>

+

+	* docs/INSTALL.UNIX: Simplify some parts, add reference to

+	autogen.sh and pointer to README.CVS.

+

+	* README.CVS: Add common problem description and solution

+	when running autogen.sh.

+

+	* docs/INSTALL: Add reference to MacOS X.

+

+	* docs/MAKEPP, docs/INSTALL.MAC: New documentation files.

+

+	* docs/TODO: Remove obsolete items.

+

+	* src/raster/ftraster.c: (TRaster_Instance): Replace it with...

+	(TWorker): This.

+	Remove `count_table' and `memory'.

+	Make `grays' a pointer.

+	(TRaster): New structure.

+	(count_table): New static array.

+	(RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,

+	Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,

+	ft_black_set_mode, ft_black_render): Updated.

+	(ft_black_init): Don't initialize `count_table'.

+	(ft_black_reset): Use the render pool.  This saves about 6KB of

+	heap space for each FT_Library instance.

+

+	* src/smooth/ftgrays.c (TRaster): Replaced with...

+	(TWorker): This.

+	Remove `memory'.

+	(TRaster): New structure.

+

+	(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,

+	gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,

+	gray_render_span, gray_raster_render): Updated.

+	(gray_raster_reset): Use the render pool.  This saves about 6KB of

+	heap space for each FT_Library instance.

+

+	* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,

+	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,

+	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove

+	FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since

+	the optimization is no longer experimental.

+

+	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):

+	Remove a typo that results in no hinting and a memory leak with some

+	large Asian CFF fonts.

+

+	* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak

+	which happens when FT_Done_Library is called with still opened

+	CFF_Faces in it.  We need to close all faces before destroying the

+	modules, or else some bad things (memory leaks) may happen.

+

+2007-01-02  Werner Lemberg  <[email protected]>

+

+	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):

+	Remove compiler warning.

+

+2007-01-02  David Turner  <[email protected]>

+

+	* src/sfnt/sfobjs.c: Add documentation comment.

+

+2006-12-31  Masatake YAMATO  <[email protected]>

+

+	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New

+	function.

+	Check uniqueness of the gid pairs.

+	(gxv_kern_subtable_fmt0_validate): Move some code to

+	`gxv_kern_subtable_fmt0_pairs_validate'.

+

+2006-12-22  David Turner  <[email protected]>

+

+	* src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler

+	warnings.

+

+	* builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE

+	to avoid deprecation warnings with Visual C++ 8.

+

+2006-12-16  Anders Kaseorg  <[email protected]>

+

+	* src/base/ftlcdfil.c (FT_Library_SetLcdFilter)

+	[FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.

+

+2006-12-15  suzuki toshiya  <[email protected]>

+

+	* include/freetype/internal/services/svotval.h: Add `volatile' to

+	sync with the modification by Jens Claudius on 2006-08-22; cf.

+	  https://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5

+

+2006-12-15  suzuki toshiya  <[email protected]>

+

+	* src/base/ftmac.c: Specialized for Mac OS X only.

+	* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.

+	* builds/unix/configure.raw: Ditto.  When explicit switches for

+	FSSpec/FSRef/QuickDraw/ATS availability are given to configure,

+	builds/mac/ftmac.c is used instead of default src/base/ftmac.c.

+

+2006-12-15  suzuki toshiya  <[email protected]>

+

+	* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.

+	* builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c

+	instead of src/base/ftmac.c

+	* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.

+	* builds/mac/FreeType.ppc_classic.make.txt: Ditto.

+	* builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c

+	that cannot be built at present.

+

+2006-12-15  suzuki toshiya  <[email protected]>

+

+	* src/base/ftobjs.c: Improvement of resource fork handler for

+	POSIX, cf.

+	  https://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html

+	(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font

+	format or .dfont, to simulate the face index number counted by ftmac.c.

+	(IsMacResource): Return the number of scalable faces correctly.

+

+2006-12-10  Werner Lemberg  <[email protected]>

+

+	* builds/toplevel.mk (version): Protect against `distclean' target.

+

+2006-12-09  Werner Lemberg  <[email protected]>

+

+	* builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'

+	or `type'.

+

+	* builds/freetype.mk (version): Extracted from freetype.h, using

+	GNU make's built-in string functions.

+	(refdoc): Use $(version) instead of static version number.

+

+2006-12-08  Werner Lemberg  <[email protected]>

+

+	* builds/toplevel.mk (dist): Extract version number from freetype.h.

+

+2006-12-08  Vladimir Volovich  <[email protected]>

+

+	* src/tools/apinames.c (State): Remove final comma in structure --

+	xlc v5 under AIX 4.3 doesn't like this.

+

+2006-12-07  David Turner  <[email protected]>

+

+	* src/autofit/afloader.c (af_loader_load_g): Small adjustment

+	to the spacing of auto-fitted glyphs.  This only impacts rare

+	cases (e.g., Arial Bold at rather small character sizes).

+

+2006-12-03  Werner Lemberg  <[email protected]>

+

+	* src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.

+

+2006-12-01  Werner Lemberg  <[email protected]>

+

+	* src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are

+	encoded in UTF-16BE.  Patch from Rajeev Pahuja <[email protected]>.

+	(tt_name_entry_ascii_from_ucs4): Removed.

+

+

+	* include/freetype/ftxf86.h: Fix and extend comment so that it

+	appears in the documentation.

+

+	* include/freetype/ftchapters.h: Add `font_format' section.

+

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::index_exit): Add link

+	to TOC in index page.

+

+2006-11-28  David Turner  <[email protected]>

+

+	* src/smooth/ftgrays.c (gray_raster_render): Return 0 when we are

+	trying to render into a zero-width/height bitmap, not an error code.

+

+	* src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.

+

+	* src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType

+	ones instead.

+

+	* src/autofit/afhints.c (af_glyph_hints_dump_segments): Remove unused

+	variable.

+

+2006-11-26  Pierre Hanser  <[email protected]>

+

+	* src/truetype/ttobjs.c (tt_face_init): Protect against NULL pointer.

+

+2006-11-25  David Turner  <[email protected]>

+

+	* src/autofit/afhints.c (af_glyph_hints_dump_points,

+	af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:

+	Add stubs to link the `ftgrid' test program when debugging is

+	disabled in the auto-hinter.

+

+2006-11-23  David Turner  <[email protected]>

+

+	* src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,

+	src/autofit/aftypes.h: Miscellaneous auto-hinter improvements.

+

+	* src/autofit/afhints.c (af_glyph_hints_dump_segments) [AF_DEBUG]:

+	Emit more sensible information.

+

+	* src/autofit/afhints.h (AF_SegmentRec): Add `height' member.

+

+	* src/autofit/aflatin.c (af_latin_metrics_scale_dim): Improve

+	rounding of blue values.

+	value and use `height' member for comparisons.

+	(af_latin_hint_edges): Extend logging message.

+	Improve handling of remaining edges.

+

+2006-11-22  Werner Lemberg  <[email protected]>

+

+	Fix Savannah bug #15553.

+

+	* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT

+	program after a change from mono to grayscaling (and vice versa).

+	Use correct constant for comparison to get `exec->grayscale'.

+

+2006-11-18  Werner Lemberg  <[email protected]>

+

+	Because FT_Load_Glyph expects CID values for CID-keyed fonts, the

+	test for a valid glyph index must be deferred to the font drivers.

+	This patch fixes Savannah bug #18301.

+

+	* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.

+	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c

+	(cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),

+	src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c

+	(pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),

+	src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c

+	(FNT_Load_Glyph): Check validity of `glyph_index'.

+

+2006-11-13  David Turner  <[email protected]>

+

+	* src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter

+	`enhancements' are still too buggy for general use.

+

+	* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and

+	FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros

+	when building the library to change the default LCD filter to be

+	used.  This is only useful for experimentation.

+

+	* include/freetype/ftlcdfil.h: Update documentation.

+

+2006-11-10  David Turner  <[email protected]>

+

+	* src/smooth/ftsmooth.c: API change for the LCD

+	filter.  The FT_LcdFilter value is an enumeration describing which

+	filter to apply, with new values FT_LCD_FILTER_LIGHT and

+	FT_LCD_FILTER_LEGACY (the latter implements the LibXft original

+	algorithm which produces strong color fringes for everything

+	except very-well hinted text).

+

+	* include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change

+	second parameter to an enum type.

+

+	* src/base/ftlcdfil.c (USE_LEGACY): Define.

+	(_ft_lcd_filter): Rename to...

+	(_ft_lcd_filter_fir): This.

+	Update parameters.

+	(_ft_lcd_filter_legacy) [USE_LEGACY]: New filter function.

+	(FT_Library_SetLcdFilter): Update parameters.

+	Handle new filter modes.

+

+	* include/internal/ftobjs.h: Include FT_LCD_FILTER_H.

+	(FT_Bitmap_LcdFilterFunc): Change third argument to `FT_Library'.

+	(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering

+	callback and update other fields.

+

+	* src/smooth/ftsmooth.c (ft_smooth_render_generic)

+	[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.

+	Other minor improvements.

+

+	* src/autofit/aflatin.c: Various tiny improvements that drastically

+	improve the handling of serif fonts and of LCD/LCD_V hinting modes.

+	(af_latin_hints_compute_edges): Fix typo.

+	(af_latin_compute_stem_width): Take better care of diagonal stems.

+

+2006-11-09  David Turner  <[email protected]>

+

+	* src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix

+	typo which created a variable-used-before-initialized bug.

+

+2006-11-07  Zhe Su  <[email protected]>

+

+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout

+	LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING

+	rendered glyph to match the one of normal gray-level rendering,

+	hence clients should not need to be modified.

+

+	* docs/CHANGES: Updated.

+

+2006-09-18  Garrick Meeker  <[email protected]>

+

+	* src/sfnt/sfobjs.c (tt_face_get_name): Support some fonts which

+

+2006-07-07  Werner Lemberg  <[email protected]>

+

+	(PCF_Face_Init): Add calls to PCF_Face_Done in case of errors.

+

+	* src/pcf/pcfread.c (pcf_read_TOC): Protect against malformed table

+	New macros which give the size of data structures in the data

+	stream.

+	(pcf_get_properties): Use rough estimates to get array size limits.

+2006-06-26  Werner Lemberg  <[email protected]>

+

+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Handle fonts correctly which

+

+2006-06-26  Jens Claudius  <[email protected]>

+

+	* src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15.

+	(t1_decoder_parse_charstrings): Operator with

+	opcode 15 pops its two arguments.

+	Handle the case where the pops of an othersubr may be part of a

+	subroutine.

+	Handle unknown othersubrs gracefully: count their operands and let

+	the following pop operators push the operands as the results onto

+	the Type1 stack.

+	Improve handling of setcurrentpoint opcode.

+

+2006-06-25  Jens Claudius  <[email protected]>

+

+	The Type 1 parser now skips over top-level procedures as required

+	for a `Simplified Parser'.  This makes the parser more robust as it

+	doesn't poke around in PostScript code.  Additionally, it makes the

+	FontDirectory hackery in src/type1/t1load.c unnecessary.

+

+	* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.

+	(skip_literal_string): Add FT_Error as return value.

+

+	* include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add

+	`first_point' member.

+

+	* src/truetype/ttgload.c (tt_prepare_zone): Initialize

+	`first_point'.

+	(TT_Process_Composite_Glyph): Always untouch points.

+

+	* src/truetype/ttinterp.c (Ins_SHC): Fix computation of

+	`first_point' and `last_point' in case of composite glyphs.

+	(Ins_IUP): Fix computation of `end_point'.

+

+2006-06-22  suzuki toshiya  <[email protected]>

+

+	Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel

+	Mac.  The original patch was written by David Sachitano and Lawrence

+	Coopet, and modified by Sean McBride for MPW compatibility.  Only

+	required data are converted; unused data are left in big endian.

+

+	* src/base/ftmac.c: Include <Endian.h> for byteorder macros for non

+	StyleMapping table.

+	(count_faces): Call `HUnlock' after all FOND utilization.

+

+2006-06-08  suzuki toshiya  <[email protected]>

+

+	Public API of TrueTypeGX, OpenType, and classic kern table validator

+	should return `FT_Err_Unimplemented_Feature' if validation service

+	is unavailable (disabled in `modules.cfg').  It is originally

+	suggested by David Turner, cf.

+	https://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

+

+	* src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return

+	classic kern table validation service is unavailable.

+

+	* src/base/ftotval.c (FT_OpenType_Validate): Return

+

+	* src/type1/t1afm.c (KERN_INDEX): Make it more robust.

+	(T1_Read_Metrics): Fix memory leak which happened when the metrics

+	file doesn't have kerning pairs.  This fixes Savannah bug #16768.

+

+2006-06-06  David Turner  <[email protected]>

+

+	Fix memory leak described in Savannah bug #16759.

+

+	We change `ps_unicodes_init' so that it also takes a

+	`free_glyph_name' callback to release the glyph names returned by

+	`get_glyph_name'

+

+	* include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):

+	Renamed to ...

+	(PS_GetGlyphNameFunc): This.

+	(PS_FreeGlyphNameFunc): New typedef.

+	(PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.

+

+	(cff_cmap_unicode_init): Updated.

+

+	* src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated.

+

+	* src/psnames/psmodule.c (ps_unicodes_init): Add variable for

+	PS_FreeGlyphNameFunc and use it.

+

+

+2006-06-04  David Turner  <[email protected]>

+

+	* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept

+	`item_size == 0' as well -- though this sounds weird, it can

+	theoretically happen.  This fixes Savannah bug #16669.

+

+	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation

+	of `face->num_glyphs' which missed the last glyph, due to

+	the offset-by-1 computation, since the PFR format doesn't

+	guarantee that glyph index 0 corresponds to the `missing

+	glyph.  This fixes Savannah bug #16668.

+

+2006-05-25  Werner Lemberg  <[email protected]>

+

+	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out

+	`-no-undefined'.  Reported by Christian Biesinger.

+

+2006-05-19  Brian Weed  <[email protected]>

+

+	* builds/win32/visualc/freetype.dsp: Release libraries no longer

+	have debug information, and debug libraries use `C7 compatible'

+	debug info.

+

+2006-05-19  suzuki toshiya  <[email protected]>

+

+	Apply patch by Derek Clegg to fix two memory leaks in the MacOS

+	resource fork handler.  This fixes Savannah bug #16631.

+

+	dependency, if configured with no options on Mac OS X.

+

+2006-05-19  suzuki toshiya  <[email protected]>

+

+	* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when

+	its content cannot be parsed as supported font.  This fixes

+	the second part of Savannah bug #16590.

+

+2006-05-18  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttgload.c (TT_Load_Composite_Glyph)

+	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

+

+2006-05-17  David Turner  <[email protected]>

+

+	This is a major patch used to drastically improve the performance of

+	loading glyphs.  This both speeds up loading the glyph vectors

+	themselves and the auto-fitter module.

+

+	We now use inline assembler code with GCC to implement `FT_MulFix',

+	which is probably the most important function related to the

+	engine's performance.

+

+	The resulting speed-up is about 25%.

+

+

+	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields

+	`cursor' and `limit'.

+

+	* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):

+	New functions.

+	(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.

+	[TEST]: Remove.

+

+	* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test

+	code.

+

+	* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call

+	`FT_ZERO'

+	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.

+	(af_glyph_hints_reload: Rewrite recognition of weak points.

+

+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move

+	constant values out of the loops.

+

+	* src/autofit/aftypes.h: Updated.

+

+	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

+

+	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector

+	product to get orientation.

+

+	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.

+	(FT_Stream_OpenGzip): Use it to handle small files directly in

+	memory.

+

+	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode):

+	Improve performance.

+

+	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and

+	`limit'.

+

+	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,

+	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against

+	exceedingly large values of number of contours.  Speed up by

+	reducing the number of loops.

+

+	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.

+

+

+	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold

+	used to detect rogue clients from 4 to 16.  This is to prevent some

+	segmentation faults with fonts like `KozMinProVI-Regular.otf' which

+	comes from the Japanese Adobe Reader Asian Font pack.

+

+2007-05-17  Werner Lemberg  <[email protected]>

+

+	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This

+	fixes the first part of Savannah bug #16590.

+

+2006-05-16  Werner Lemberg  <[email protected]>

+

+	* docs/PROBLEMS: Updated icl issues.

+

+	[cff] Make Adobe CFF engine work correctly on 64bit hosts.

+

+	Reported by numerous people on the `freetype-devel' list.  Without

+	this fix, glyphs aren't properly aligned on a common baseline.

+

+	On 64bit systems, `FT_Pos' expands to `long int', having a width of

+	64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on

+	64bit hosts also.  Wrong casts filled up the blues arrays with

+	incorrect values.  Note that all blues values are accessed with the

+	`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.

+

+	* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,

+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for

+	`data', not `CF2_Fixed'.

+	* src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,

+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.

+	* src/cff/cf2blues.c (cf2_blues_init): Updated.

+

+2013-05-04  Werner Lemberg  <[email protected]>

+

+	More fixes for clang's `sanitize' feature.

+

+	* src/base/ftcalc.c (FT_DivFix): Use unsigned values for

+	computations which use the left shift operator and convert to signed

+	as the last step.

+	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,

+	FT_Vector_Length, FT_Vector_Polarize): Ditto.

+

+	* src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,

+	cf2_fracToFixed): Avoid shifts of negative values.

+	(cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,

+	unused.

+

+	* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,

+	default>: Use unsigned values for computations and convert to signed

+	as the last step.

+	Use proper types in tracing messages.

+

+	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned

+	values for computation of operands and convert to signed as the last

+

+2013-04-13  Werner Lemberg  <[email protected]>

+

+	[cff] Add a new Type 2 interpreter and hinter.

+

+	This work, written by Dave Arnold <[email protected]> and fully

+	integrated into FreeType by me, is a donation by Adobe in

+	collaboration with Google.  It is vastly superior to the old CFF

+	engine, and it will replace it soon.  Right now, it is still off by

+	default, and you have to explicitly select it using the new

+	`hinting-engine' property of the cff driver.

+

+	For convenience, (most of) the new files are committed separately.

+

+	* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.

+	* include/freetype/ftcffdrv.h: New file to access CFF driver

+	properties.

+	* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error

+	code.

+	* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',

+	and `cf2interp'.

+

+	* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.

+	* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'

+	and `no_stem_darkening'.

+	* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.

+

+	* src/cff/cff.c: Include new files.

+	* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle

+	`hinting-engine' and `no-stem-darkening' properties (only the Adobe

+	engine listens to them).

+	* src/cff/cffgload.c: Include `cf2ft.h'.

+	(cff_decoder_prepare): Initialize `current_subfont'.

+

+	This is a purely mechanical conversion.

+

+2013-03-14  Werner Lemberg  <[email protected]>

+

+	*/*: Use `FT_THROW'.

+

+	This is essentially a mechanical conversion, adding inclusion of

+	`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for

+	stand-alone compiling modes of the rasterizer modules.

+

+	To convert the remaining occurrences of FT_Err_XXX and friends it is

+	necessary to rewrite the code.  Note, however, that it doesn't harm

+	if some cases are not handled since FT_THROW is a no-op.

+

+2013-03-13  Werner Lemberg  <[email protected]>

+

+	Introduce `FT_THROW' macro.

+

+	The idea is to replace code like

+

+	  return FT_Err_Foo_Bar;

+

+	or

+

+	  return CFF_Err_Foo_Bar;

+

+	with

+

+	  return FT_THROW( Foo_Bar );

+

+	The FT_THROW macro has two functions:

+

+	  . It hides the module specific prefix.

+

+	  . In debug mode, it calls the empty function `FT_Throw' which can

+	    be thus used to set a breakpoint.

+

+	* include/freetype/internal/ftdebug.h (FT_THROW): New macro.

+	(FT_Throw): New prototype.

+	* src/base/ftdebug.c (FT_Throw): New function.

+

+2013-03-12  Werner Lemberg  <[email protected]>

+

+	Remove `FT_KEEP_ERR_PREFIX'.

+

+	The idea is to always have FT_ERR_PREFIX available internally.

+

+	* include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard

+	undefinition of FT_ERR_PREFIX

+

+	* src/gxvalid/gxverror.h, src/otvalid/otverror.h,

+	src/sfnt/sferrors.h: Updated.

+

+	* builds/unix/freetype-config.in: Remove code for handling `rpath'.

+	The use of $rpath has been accidentally removed in a patch from

+

+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.

+	BTW, Greg agrees that the OpenType specification is missing the list

+	of GS variables which will always be reset to the default values

+	after the `prep' table has been executed.

+

+2013-02-06  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.

+

+	Up to now, we simply took a snapshot of the Graphics State after the

+	`prep' table has been executed, and right before a glyph's bytecode

+	was run it got reloaded.  However, as Greg Hitchcock has told us in

+	private communication, reference points get reset to zero in the MS

+	rasterizer and we follow in due course.  While reasonable, this is

+	undocumented behaviour.

+

+	Most notably, this fixes the rendering of Arial's `x' glyph in

+	subpixel hinting mode.

+

+	[truetype] Improve subpixel code.

+

+	This patches fixes many issues with the ttsubpix implementation.

+

+	1. Data tables are defined, instead of declared, in the header, and

+	   thus copied into each source file that includes it.

+

+	2. These tables were defined as global, mutable, visible variables,

+	   and thus costing private RAM to every process that loads the

+	   library (> 50 KB / process, this is huge!).

+

+	   Additionally, this also made the library export the symbols

+	   completely needlessly.

+

+	3. Missing `sph_' and `SPH_' prefixes to some of the definitions.

+

+	Note that this doesn't try to fix the incredibly inefficient storage

+	format for the data tables used by the code.  This one will require

+	another pass in the future.

+2012-12-20  Alexei Podtelezhnikov  <[email protected]>

+

+	[base] Improve trigonometric core.

+

+	FreeType used to rely on a 24-step iteration CORDIC algorithm to

+	calculate trigonometric functions and rotate vectors. It turns out

+	that once the vector is in the right half-plane, the initial rotation

+	by 63 degrees is not necessary. The algorithm is perfectly capable

+	to converge to any angle starting from the second 45 degree rotation.

+	This patch removes the first rotation and makes it a 23-step CORDIC

+	algorithm.

+

+	* src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro

+	values.

+	(ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial

+

+	Various compiler warning fixes.

+

+	* include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use

+

+2012-12-15  Alexei Podtelezhnikov  <[email protected]>

+

+	[base] Fix 11-year old bug.

+

+	Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has

+	always been slightly less than the correct value, which has been

+	given in the comment as a hexadecimal. As a result, vector lengths

+	were underestimated and rotated vectors were shortened.

+

+	* src/base/fttrigon.c (FT_TRIG_SCALE): Fix macro value.

+

+2012-12-15  Werner Lemberg  <[email protected]>

+

+

+2012-12-10  Alexei Podtelezhnikov  <[email protected]>

+

+	[truetype] Scale F_dot_P down.

+

+	The dot product between freeVector and projVector or cosine of

+	the angle between these FT_F2Dot14 unit vectors used to be scaled up

+	by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.

+	This patch scales the value down by 2^14 instead, which simplifies

+	its use throughout the bytecode interpreter.

+

+	This does not lead to the loss of precision because the lower bits

+	are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)

+	for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.

+	These vectors are stored as (0x4000,0) and (0x2666,0x3333) after

+	rounding and F_dot_P is assigned 0x26660000. The lower bits were

+	already lost while rounding the unit vector components.

+

+	Besides code simplification, this change can lead to better

+	performance when FT_MulDiv with the scaled-down F_dot_P is less

+	likely to use the costly 64-bit path. We are not changing the type

+	of F_dot_P to FT_F2Dot14 at this point.

+

+	* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14

+	bits and modify its use accordingly.

+	(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify

+	the use of F_dot_P field.

+	* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary

+	assignment of F_dot_P to its theoretical maximum in case we decide

+	to scale back its type later.

+	The subpixel hinting patch contained the concept of an adjustable

+

+	[truetype] Support subpixel hinting.

+

+	This is the large, famous `Infinality' patch to support ClearType

+	bytecode which has been available from

+	http://www.infinality.net/blog/ for some time, and which has been

+	refined over the last years.  While still experimental, it is now

+	mature enough to be included directly into FreeType.

+

+	Most of the code is based on the ClearType whitepaper written by

+	Greg Hitchcock

+

+	  https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

+

+	which gives a detailed overview of the necessary changes to the

+	Microsoft rasterizer so that older fonts are supported.  However, a

+	lot of details are still missing, and this patches provides a

+	framework to easily handle rendering issues down to the glyph level

+	of certain fonts.

+

+	Note that ClearType support is not completely implemented!  In

+	particular, full support for the options `compatible_widths',

+	`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode

+	instruction) is missing.

+

+	* src/truetype/ttsubpix.c: New file, providing code to handle

+	`tweaks', this is, rules for certain glyphs in certain fonts

+	(including wildcards) which need a special treatment.

+

+	* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

+

+	* include/freetype/config/ftoption.h, src/devel/ftoption.h

+	(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

+

+	[autofit] Return correct linear advance width values.

+

+	This was quite a subtle bug which accidentally showed up with glyph

+	`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;

+	the first component, `E', has an advance width of 1366 font units,

+	while the advance width of the composite itself (which looks like

+	uppercase `E' with dieresis) is 1367 font units.  I think this is

+	actually a bug in the font itself, because there is no reason that

+	this glyph has not the same width as uppercase `E' without the

+	dieresis.  Anyway, it helped identify this problem.

+

+	Using the TrueType hinter, the correct value (1367) of `afii10023'

+	was returned, but the autohinter mysteriously returned 1366.

+

+	Digging in the code showed that the autohinter recursively calls

+	FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load

+	flag.  However, the `linearHoriAdvance' field is still returned as a

+	scaled value.  To avoid scaling twice, the old code in autofit reset

+	`linearHoriAdvance', using the `horiAdvance' field.  This seemed to

+	work since FT_LOAD_NO_SCALE was in use, but it failed actually,

+	because `horiAdvance' is defined as the distance of the first

+	subglyph's phantom points, which in turn are initialized using the

+	advance width of the first subglyph.  And as the given example

+	shows, these widths can differ.

+

+	* src/autofit/afloader.c (af_loader_load_g): Temporarily set

+	FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled

+	values for the linear advance widths.

+	this instruction.

+	* include/freetype/internal/ftrfork.h: Here.

+

+	FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined

+	to replace raccess_guess_table[] in both of PIC and non-PIC

+	* src/base/ftrfork.c: raccess_guess_table[] array is rewritten

+

+	[cff] Remove redundant declarations of cff_cmap_XXX_class_rec.

+

+	* src/cff/cffpic.c: The declarations of

+	FT_Init_Class_cff_cmap_encoding_class_rec() and

+	FT_Init_Class_cff_cmap_unicode_class_rec() are removed.

+	They can be obtained by the inclusion of cffcmap.h.

+	cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares

+	FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.

+

+2012-01-15  suzuki toshiya  <[email protected]>

+

+	Fix redundant declaration warning in PIC mode.

+

+	Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were

+	designed to declare xxx_pic_{free,init} by themselves.

+	Because these macros are used at the end of the module

+	interface (e.g. ttdriver.c) and the wrapper source to build

+	a module as a single object (e.g. truetype.c) includes

+	the PIC file (e.g. ttpic.c) before the module interface,

+	these macros are expanded AFTER xxx_pic_{free,init} body

+	when the modules are built as single object.

+	The declaration after the implementation causes the redundant

+	declaration warnings, so the declarations are moved to module

+	PIC headers (e.g. ttpic.h).  Separating to other header files

+	are needed for multi build.

+

+	* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):

+	Remove class_##_pic_free and class_##_pic_init declarations.

+	* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,

+	FT_DEFINE_MODULE): Ditto.

+

+	* src/base/basepic.h: Insert a comment and fix coding style.

+	* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,

+	init}.

+	* src/psnames/pspic.h: Declare psnames_module_class_pic_{free,

+	init}.

+	* src/raster/rastpic.h: Declare

+	ft_raster{1,5}_renderer_class_pic_{free,init}

+	* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.

+	* src/smooth/ftspic.h: Declare

+	reordered to minimize PIC conditionals.

+2012-01-14  suzuki toshiya  <[email protected]>

+

+	[base] Insert explicit cast for GCC 4.6 in PIC mode.

+

+	* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC

+	FT_Module_Class** pointer, GCC 4.6 warns that

+	const FT_Module_Class* const* variable is warned as

+	inappropriate to store it.  To calm it, explicit cast is

+	inserted.  Also `library' is checked to prevent the NULL

+	pointer dereference in FT_DEFAULT_MODULES_GET.

+

+	[mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.

+

+	Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON

+	was a configurable macro to disable Carbon-dependent code.  Because

+	now configure script sets DARWIN_NO_CARBON by default and disables

+	Darwin & Carbon-dependent codes, these macros can be unified.

+	FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON

+	(defined by default) is removed, because DARWIN_NO_CARBON violates

+	FT_XXX naming convention of public macros, and a macro configured by

+	default is not portable for the building without configure (e.g.

+	make devel).

+

+	* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based

+	old Mac font support is requested and Carbon is available.

+	* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support

+	for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is

+	[smooth] Slightly optimize conic and cubic flatteners.

+	out some code from the main loop to speed it up.

+

+2011-09-11  Tomas Hoger  <[email protected]>

+

+	Slightly improve LZW_CLEAR handling.

+

+	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:

+	Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are

+	handled as clear codes.  This also re-sets old_code and old_char to

+	predictable values, which is a little better than using `random'

+	ones if the code following LZW_CLEAR is invalid.

+

+2011-09-11  Tomas Hoger  <[email protected]>

+

+	Add explicit LZW decompression stack size limit.

+

+	Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is

+	constructed correctly.  It's even less than that, see e.g.

+	libarchive code comment for a better size upper bound:

+

+	  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121

+

+	This patch adds explicit stack size limit, enforced when stack is

+	realloced.

+

+	An alternative is to ensure that code < state->prefix[code - 256]

+	when traversing prefix table.  Such check is less efficient and

+	should not be required if prefix table is constructed correctly in

+	the first place.

+

+	* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.

+

+2011-09-11  Tomas Hoger  <[email protected]>

+

+	Protect against loops in the prefix table.

+

+	LZW decompressor did not sufficiently check codes read from the

+	input LZW stream.  A specially-crafted or corrupted input could

+	create a loop in the prefix table, which leads to memory usage

+	spikes, as there's no decompression stack size limit.

+

+	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First

+	code in valid LZW stream must be 0..255.

+	<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,

+	code > free_ent is invalid.

+

+	[ftstroke] Major revision.

+

+	The main problems

+	-----------------

+

+	  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter

+	    joins (not bevel joins) were generated.  Indeed, the meanings of

+	    `miter' and `bevel' were incorrectly reversed (consistently) in

+	    both the code and comments.

+

+	  o The way bevel joins were constructed (whether specified

+	    explicitly, or created as a result of exceeding the miter limit)

+	    did not match what is required for stroked text in PostScript or

+	    PDF.

+

+	The main fixes

+	--------------

+

+	  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

+

+	  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been

+	    introduced to support PostScript and PDF miter joins.

+

+	  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an

+	    alias for FT_STROKER_LINEJOIN_MITER.

+

+	Additionally, a variety of stroking errors have been fixed.  These

+	would cause various artifacts (including points `at infinity'),

+	especially when stroking poor quality fonts.

+

+	See

+

+	  https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html

+

+	for example documents.  The FreeType stroker now produces results

+	very similar to that produced by GhostScript and Distiller for these

+	fonts.

+

+	Other problems

+	--------------

+

+	The following problems have been resolved:

+

+	  o Inside corners could be generated incorrectly.  Intersecting the

+	    inside corner could cause a missing triangular area and other

+	    effects.

+

+	    The intersection point can only be used if the join is between

+	    two lines and both lines are long enough.  The `optimization'

+	    condition in `ft_stroker_inside' has been corrected; this

+	    requires the line length to be passed into various functions and

+	    stored in `FT_StrokerRec'.

+

+	  o Incorrect cubic curves could be generated.  The angle

+	    calculations in `FT_Stroker_CubicTo' have been corrected to

+	    handle the case of the curve crossing the +/-PI direction.

+

+	  o If the border radius was greater than the radius of curvature of

+	    a curve, then the negative sector would end up outside (not

+	    inside) the border.  This situation is now recognized and the

+	    negative sector is circumnavigated in the opposite direction.

+	    (If round line joins are being used, this code is disabled

+	    because the line join will always cover the negative sector.)

+

+	  o When a curve is split, the arcs may not join smoothly (especially

+	    if the curve turns sharply back on itself).  Changes in

+	    direction between adjacent arcs were not handled.  A round

+	    corner is now added if the deviation from one arc to the next is

+	    greater than a suitable threshold.

+

+	  o The current direction wasn't retained if a the outline contained

+	    a zero length lineto or a curve that was determined to be

+	    `basically a point'.  This could cause a spurious join to be

+	    added.

+

+	  o Cubics with close control points could be mishandled.  All eight

+	    cases are now distinguished correctly.

+

+	Other improvements

+	------------------

+

+	o Borders for cubic curves could be too `flat'.

+	  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent

+	  this.

+

+	o The handling and use of movable points has been simplified a

+	  little.

+

+	o Various values are now computed only if the results are actually

+	  needed.

+

+	o The directions of the outer and inner borders have been swapped,

+	  as recommended by Graham Asher.

+

+	[cache] Fix Savannah bug #31923, patch drafted by Harsha.

+

+	When a node comparator changes the cached nodes during the

+	search of a node matching with queried properties, the

+	pointers obtained before the function should be updated to

+	prevent the dereference to freed or reallocated nodes.

+	To minimize the rescan of the linked list, the update is

+	executed when the comparator notifies the change of cached

+	nodes. This change depends previous change:

+	38b272ffbbdaae276d636aec4ef84af407d16181

+

+	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the

+	top node if the cached nodes are changed.

+	* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.

+

+2011-01-09  suzuki toshiya  <[email protected]>

+

+	[cache] Notice if a cache query induced the node list change.

+

+	Some node comparators (comparing the cache node contents and the

+	properties specified by the query) can flush the cache node to

+	prevent the cache inflation.  The change may invalidate the pointers

+	to the node obtained before the node comparison, so it should be

+	noticed to the caller.  The problem caused by the cache node

+	changing is reported by Harsha, see Savannah bug #31923.

+

+	* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument

+	`FT_Bool* list_changed' to indicate the change of the cached nodes

+	to the caller.

+	(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by

+	`_list_changed'.

+	(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'

+	and update it when `FTC_Manager_FlushN' flushes any nodes.

+

+	* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new

+	FTC_Node_CompareFunc type.

+	(ftc_gnode_compare): Ditto.

+	is always FALSE).

+

+	* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use

+	TRUE/FALSE macros.

+	(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to

+	(ftc_cmap_node_remove_faceid): Ditto.

+

+	* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to

+	`FTC_CACHE_TRYLOOP_END', because the result is not needed.

+	(FTC_Cache_Lookup): Watch the change of the cache nodes by

+	`list_changed'.

+	(FTC_Cache_RemoveFaceID): Ditto.

+	(FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be

+	passed to `ftc_gnode_compare'.

+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.

+

+	* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*

+	list_changed' to indicate the change of the cache nodes, anyway.  It

+	is updated by `FTC_CACHE_TRYLOOP'.

+	(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be

+	passed to `ftc_snode_compare'.

+	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

+2011-01-09  suzuki toshiya  <[email protected]>

+

+	[cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.

+

+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd

+	argument `FTC_Cache  cache' to fit FTC_Node_CompareFunc

+	prototype.

+	* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,

+	`cache' is not used by its child `ftc_gnode_compare'.

+

+2011-01-09  suzuki toshiya  <[email protected]>

+

+	[cache] Deduplicate the code to get the top node by a hash.

+

+	There are several duplicated code fragments getting the top node

+	from a cache by a given hash, like:

+

+	    if ( idx < cache->p )

+	      idx = hash & ( cache->mask * 2 + 1 );

+	    pnode = cache->buckets + idx;

+

+	To remove duplication, a cpp-macro to do same work

+	`FTC_NODE__TOP_FOR_HASH' is introduced.  For non-inlined

+	configuration, non-`ftc_get_top_node_for_hash' is also introduced.

+

+	* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare

+	and implement inlined version.

+	(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.

+	* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined

+	(FTC_Cache_Lookup): Ditto.

+

+2011-01-09  suzuki toshiya  <[email protected]>

+

+	[cache] inline-specific functions are conditionalized.

+

+	* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for

+	inlined configuration.  This function is a thin wrapper of

+	`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see

+	`nodecmp' argument).  Under non-inlined configuration,

+	`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via

+	`FTC_Cache->clazz.node_compare'.

+

+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.

+	* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for

+	`ftc_snode_compare'.

+	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

+

+2011-01-09  suzuki toshiya  <[email protected]>

+

+	[cache] Correct a type mismatch under non-inlined config.

+

+	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'

+

+	If we encounter a space in a string then the sbit buffer is NULL,

+

+2010-10-24  suzuki toshiya  <[email protected]>

+

+	[cache] Change the hash types to FT_PtrDist.

+

+	On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)

+	variables are inappropriate to calculate hash values

+	from the memory address (64-bit).  The hash variables

+	are extended from FT_ULong to FT_PtrDist and new

+	hashing macro functions are introduced.  The hash

+	values on 16-bit memory platforms are changed, but

+	ILP32 and LP64 are not changed.  The hash value in

+	the cache subsystem is not reverted to the memory

+	address, so using signed type FT_PtrDist is safe.

+

+	* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash

+	function to replace `FTC_FACE_ID_HASH' for portability.

+	* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace

+	* src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.

+

+	* src/cache/ftccache.h (FTC_NodeRec): The type of the

+	member `hash' is changed from FT_UInt32 to FT_PtrDist.

+

+	* src/cache/ftccache.h (FTC_Cache_Lookup): The type of the

+	argument `hash' is changed from FT_UInt32 to FT_PtrDist.

+	(FTC_Cache_NewNode): Ditto.

+	* src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.

+

+	* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type

+	(FTC_SBitCache_LookupScaler): Ditto.

+	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.

+	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.

+	Also the type of the internal variable `_idx' is changed to

+	FT_PtrDist from FT_UFast for better pointer calculation.

+

+2010-10-24  suzuki toshiya  <[email protected]>

+

+	[cache] Hide internal macros incompatible with LLP64.

+

+	`FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and

+	`FTC_IMAGE_TYPE_HASH' are enclosed by

+	FT_CONFIG_OPTION_OLD_INTERNALS and hidden from

+	normal clients.

+

+2010-10-24  suzuki toshiya  <[email protected]>

+

+	Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.

+

+	On LLP64 platforms (e.g. Win64), unsigned long (32-bit)

+	cannot cover the memory address (64-bit).  `FT_MEM_VAL' is

+	used for hashing only and not dereferred, so using signed

+	type FT_PtrDist is safe.

+

+	* src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the

+	return value from FT_ULong to FT_PtrDist.

+	(ft_mem_table_resize): The type of hash is changed to

+	FT_PtrDist.  (ft_mem_table_get_nodep): Ditto.

+

+2010-10-24  suzuki toshiya  <[email protected]>

+

+	Replace "%lx" for memory address by "%p", LLP64 platforms.

+

+	On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover

+	the memory address (64-bit).  Also the casts from the pointer

+	type to long int should be removed to preserve the address

+	correctly.

+

+	* src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".

+	(End_Profile) Ditto.

+	* src/truetype/ttinterp.c (Init_Context): Ditto.

+

+2010-10-15  Alexei Podtelezhnikov  <[email protected]>

+

+	[raccess] Skip unrequired resource access rules by Darwin VFS.

+

+	When a resource fork access rule by Darwin VFS could open the

+	resource fork but no font is found in it, the rest of rules

+	by Darwin VFS are skipped.  It reduces the warnings of the

+	deprecated resource fork access method by recent Darwin kernel.

+	Fix MacPorts ticket #18859:

+		https://trac.macports.org/ticket/18859

+

+	* src/base/ftobjs.c (load_face_in_embedded_rfork):

+	When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it

+	means that the file is possible to be `fopen'-ed but zero-sized.

+	Also there is a case that the resource fork is not zero-sized,

+	but no supported font exists in it.  If a rule by Darwin VFS

+	falls into such cases, there is no need to try other Darwin VFS

+	rules anymore.  Such cases are marked by vfs_rfork_has_no_font.

+	If it is TRUE, the Darwin VFS rules are skipped.

+

+2010-10-13  suzuki toshiya  <[email protected]>

+

+	[raccess] Grouping resource access rules based on Darwin VFS.

+

+	MacOS X/Darwin kernel supports a few tricky methods to access

+	a resource fork via ANSI C or POSIX interface.  Current resource

+	fork accessor tries all possible methods to support all kernels.

+	But if a method could open a resource fork but no font is found,

+	there is no need to try other methods older than tested method.

+	To determine whether the rule index is for Darwin VFS, a local

+	function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.

+	To use this function in ftobjs.c etc but it should be inlined,

+	it is exposed by ftbase.h.

+

+	* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify

+	the rules to access the resource fork.

+	(raccess_guess_rec): New structure to bind the rule function and

+	rule enum type.

+	(FT_Raccess_Guess): The list of the rule functions is replaced by

+	(raccess_guess_table): This.  This is exposed to be used by other

+	intra module functions.

+	(raccess_rule_by_darwin_vfs): A function to return a boolean

+	if the rule specified by the rule index is based on Darwin VFS.

+

+2010-10-13  suzuki toshiya  <[email protected]>

+

+	Prevent to open a FT_Stream for zero-sized file on non-Unix.

+

+	builds/unix/ftsystem.c prevents to open an useless stream from

+	zero-sized file and returns FT_Err_Cannot_Open_Stream, but the

+	stream drivers for ANSI C, Amiga and VMS return useless streams.

+	For cross-platform consistency, all stream drivers should act

+	same.

+

+	* src/base/ftsystem.c (FT_Stream_Open): If the size of the opened

+	file is zero, FT_Err_Cannot_Open_Stream is returned.

+	* builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.

+	* src/vms/ftsystem.c (FT_Stream_Open): Ditto.

+	Ignore the environmental setting of LIBTOOL.

+	Patch is suggested by Adrian Bunk, to prevent unexpected

+	reflection of environmental LIBTOOL.  See:

+	https://savannah.nongnu.org/patch/?7290

+

+	* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to

+	$(FT_LIBTOOL_DIR)/libtool.  FT_LIBTOOL_DIR is set to $(BUILD_DIR)

+	by default.

+	* configure: When configured for the building out of source tee,

+	FT_LIBTOOL_DIR is set to $(OBJ_DIR).

+

+	[truetype] Prevent bytecode reuse after the interpretation error.

+

+	* src/truetype/ttinterp.c (free_buffer_in_size): New function to

+	free the buffer allocated during the interpretation of this glyph.

+	(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if

+	an error occurs in the bytecode interpretation.  The interpretation

+	of invalid bytecode may break the function definitions and referring

+	them in later interpretation is danger.  By unsetting these flags,

+	`fpgm' and `prep' tables are executed again in next interpretation.

+

+	This fixes Savannah bug #30798, reported by Robert Święcki.

+

+	Force hinting when the font lacks its familyname.

+

+	In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt

+

+2010-05-10  Ken Sharp  <[email protected]>

+

+	[psaux] Fix Savannah bug #29846.

+

+	Previously we discovered fonts which used `setcurrentpoint' to set

+	the initial point of a contour to 0,0.  This caused FreeType to

+	raise an error, because the `setcurrentpoint' operator is only

+	supposed to be used with the results from an OtherSubr subroutine.

+

+	This was fixed by simply ignoring the error and carrying on.

+

+	Now we have found a font which uses setcurrentpoint to actually

+	establish a non-zero point for a contour during the course of a

+	glyph program.  FWIW, these files may be produced by an application

+	called `Intaglio' on the Mac, when converting TrueType fonts to

+	Type 1.

+

+	The fix allows the new invalid behaviour, the old invalid behaviour

+	and real proper usage of the operator to work the same way as Adobe

+	interpreters apparently do.

+

+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make

+	`setcurrentpoint' use the top two elements of the stack to establish

+	unconditionally the current x and y coordinates.

+

+	Make the `flex' subroutine handling (OtherSubr 0) put the current

+	x,y coordinates onto the stack, instead of two dummy uninitialised

+	values.

+2010-04-14  Ken Sharp  <[email protected]>

+

+	[psaux] Fix Savannah bug #29444.

+

+	* src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid)

+2010-04-14  Michał Cichoń  <[email protected]>

+

+	[psaux] Fix Savannah bug #27999.

+

+	* src/cache/ftcmanag.c (FTC_Manager_RemoveFaceID): Only remove

+	selected entry, not all.

+

+2010-04-06  Jonathan Kew  <[email protected]>

+

+	[truetype] Add overflow check to `fvar' table.

+

+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance

+

+2010-04-05  Ken Sharp  <[email protected]>

+

+	[raster] Fix Savannah bug #29335.

+	however.

+

+2010-04-05  Werner Lemberg  <[email protected]>

+

+	Add new function `FT_Library_SetLcdFilterWeights'.

+	FreeDesktop bug #27386.

+

+	* src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights): New

+	function.

+

+	[otvalid] Fix a naming convention conflicting with ftvalid.

+

+	Some prototypes in ftvalid.h use `valid' for the variables

+	typed as FT_Validator.  Their implementations in src/base/

+	ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.

+

+	Some macros in otvcommn.h assume the exist of the variable

+	`valid' typed as OTV_Validator in the caller.

+

+	Mixing these two conventions cause invalid pointer conversion

+	and unexpected SEGV in longjmp.  To prevent it, all variables

+	typed as OTV_Validator are renamed to `otvalid'.

+

+	* src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.

+	* src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,

+

+	[cff] Modify an FT_ASSERT.

+

+	* src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah

+	bug #43661, the test font `...aspartam.otf' still triggers an

+	FT_ASSERT.  Since hintmap still works with count==0, ...

+	(cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to

+

+	[autofit] Better fix for conversion specifiers in debug messages.

+

+	Using `%ld' for pointer differences causes warnings on 32bit

+	platforms.  The correct type would be (the relatively new) `%td',

+	however, this is missing on some important platforms.

+

+	This patch improves the change from 2014-11-28.

+

+	* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast.  Our

+	pointer differences are always sufficiently small.

+	(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,

+	af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

+

+2014-12-03  Werner Lemberg  <[email protected]>

+

+	FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality.

+

+	All public FreeType enumeration and flag values are uppercase...

+

+	* include/tttables.h (FT_Sfnt_Tag): Implement it.  For backward

+	compatibility, retain the old values as macros.

+

+	* src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c

+	(get_sfnt_table): Updated.

+

+2014-12-02  Werner Lemberg  <[email protected]>

+

+	* include/*: Improve structure of documentation.

+

+	. Add and update many `<Order>' tags.

+	. Apply various documentation fixes.

+	. Remove details to deprecated (or never implemented) data.

+

+2014-12-02  Werner Lemberg  <[email protected]>

+

+	[docmaker] Always handle `<Order>' section elements.

+

+	Previously, those elements were handled only for sections present in

+	a `<Sections>' chapter element.

+

+	* src/tools/docmaker/content.py (ContentProcessor::finish):

+	Implement it.

+

+2014-12-02  Werner Lemberg  <[email protected]>

+

+	[docmaker] Properly handle empty rows in Synopsis.

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit

+	` ' for empty fields.

+

+2014-12-02  Werner Lemberg  <[email protected]>

+

+	[docmaker] Thinko.

+

+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

+	Emit `/empty/' string for first element also.

+

+2014-12-02  Werner Lemberg  <[email protected]>

+

+	[docmaker] Honour empty lines in `<Order>' section element.

+

+	This greatly improves the readability of the `Synopsis' links.

+

+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

+	Insert string `/empty/' between items.

+

+	* src/tools/docmaker/formatter.py (Formatter::section_dump): Make it

+	robust against nonexistent keys.

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit

+	empty <td> elements for `/empty/'.

+

+2014-12-02  Werner Lemberg  <[email protected]>

+

+	[docmaker] Ensure Python 3 compatibility.

+

+	* src/tools/docmaker/content.py (ContentProcessor::set_section,

+	ContentProcessor::finish): Replace `has_key' function with `in'

+	keyword.

+

+	* src/tools/docmaker/formatter.py (Formatter::__init__): Replace

+	sorting function with a key generator.

+	(Formatter::add_identifier): Replace `has_key' function with `in'

+	keyword.

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote):

+	Replace `has_key' function with `in' keyword.

+	integer division.

+	s/<>/>/.

+

+	* src/tools/docmaker/utils.py: Import `itertools'.

+	(index_sort): Replaced by...

+	(index_key): ... this new key generator (doing exactly the same).

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	[docmaker] Don't output a block multiple times.

+

+	This bug was hidden by not processing all lines of `<Order>' blocks.

+

+	* src/tools/docmaker/formatter.py (Formatter::section_dump): Filter

+	out field names.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	[docmaker] Use field values as HTML link targets where possible.

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url):

+	Accept second, optional argument to specify a name.

+	(HtmlFormatter::html_source_quote): Link to field ID if possible.

+	(HtmlFormatter::print_html_field_list): Emit `id' attribute.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	[docmaker] Allow empty lines in `<Order>' blocks.

+

+	Before this patch, the suggested order of entries stopped at the

+	first empty line.

+

+	Obviously, nobody noticed that this problem caused a much reduced

+	set of links in the `Synopsis' sections; in particular, the

+	`<Order>' blocks contain a lot of entries that wouldn't be listed

+	otherwise...

+

+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

+	New function to iterate over all items.

+	(DocSection::process): Use it.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp.

+

+	After the single asterisk there must be no other immediately following

+	asterisk.

+

+	* src/tools/docmaker/tohtml.py: Introduce a new table class `toc',

+	together with proper CSS.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	[docmaker] Provide higher-level markup and simplify HTML.

+

+	* src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'

+	elements, use CSS descendants (of class `section') to format the

+	data.

+

+	Also remove redundant <p> and <br> elements, replacing them with

+	proper CSS.

+

+	Globally reduce page width to 75%.

+

+	(block_header): Rename <div> class to `section'.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	[docmaker] Add `top' links after blocks.

+

+	* src/tools/docmaker/tohtml.py (block_footer_middle): Implement it.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Improve CSS for fields.

+

+	Make fields align horizontally relative to full line width.

+

+2014-11-29  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Fix index and TOC templates.

+

+	This thinko was introduced 2014-11-27.

+

+2014-11-28  Werner Lemberg  <[email protected]>

+

+	[docmaker] Format field lists with CSS.

+

+	This also simplifies the inserted HTML code.

+

+	* src/tools/docmaker/tohtml.py

+	(HtmlFormatter::print_html_field_list): Do it.

+

+2014-11-28  suzuki toshiya  <[email protected]>

+

+	Fix compiler warning to the comparison between signed and

+	unsigned variable.

+

+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison

+	between `ypos + ysize' and FT_INT_{MAX,MIN}.

+

+2014-11-28  Werner Lemberg  <[email protected]>

+

+	[docmaker] Replace empty `<td>' with CSS.

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do

+	it.

+

+2014-11-28  Werner Lemberg  <[email protected]>

+

+	[docmaker] Replace some `<table>' tags with `<h4>' and `<div>'.

+

+	* src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'.

+	(source_*): Use `<div>'.

+	(HtmlFormatter::block_enter): s/<h4>/<h3>/.

+

+2014-11-28  suzuki toshiya  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Use more CSS for index.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	[docmaker] Replace `name' attribute of `<a>' with `id'.

+

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.

+

+	For `Index' and `TOC' links, we now simply use the `text-align' CSS

+	property of `<td>' to enforce flush-left and flush-right,

+	eliminating the hack with an empty, full-width `<td>' element

+	inbetween.

+

+	The change also enforces the same (smaller) size for all index and

+	TOC links.

+

+2014-11-27  suzuki toshiya  <[email protected]>

+

+	* src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(),

+	cf2font.c could not find it under `make multi' build.

+

+2014-11-27  suzuki toshiya  <[email protected]>

+

+	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	Replace some `<table>' tags with `<div>' to simplify structure.

+

+	Move `bgcolor' attribute to CSS.

+

+	Replace most `width' attributes with CSS.  The remaining instances

+	(providing a similar effect as LaTeX's `\hfill' command) are removed

+	in a later patch.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Replace <font> with CSS.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Center <table> with CSS.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Replace `<center>' with `<div>'.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/tohtml.py: Remove redundant `<center>' tags.

+

+	This starts a series of commits into the direction of generating

+	valid HTML 5 code, especially using much more CSS.

+

+2014-11-27  suzuki toshiya  <[email protected]>

+	values in `width' and `height' are checked.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	[docmaker] Produce better HTML code.

+

+	* src/tools/docmaker/tohtml.py: Always use double quotes for

+	attribute values.

+	(source_footer): Close `td' and `tr' groups.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	Use better way to disable creation of .pyc files for `make refdoc'.

+

+	Python 2.6 was released in 2008...

+

+	* builds/freetype.mk (refdoc): Use python's `-B' option.

+

+	* builds/detect.mk (std_setup, dos_setup): Mention required python

+	version for `refdoc' target.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	* src/tools/docmaker/sources.py (re_bold, re_italic): Use

+	non-grouping parentheses.

+	Updated.

+

+2014-11-27  Werner Lemberg  <[email protected]>

+

+	Introduced in previous change.  Reported by Alexei.

+

+2014-11-26  Werner Lemberg  <[email protected]>

+

+	* src/*: Add checks for parameters of API functions where missing.

+

+	`API functions' are functions tagged with `FT_EXPORT_DEF'.

+

+	Besides trivial fixes, the following changes are included, too.

+

+	* src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set

+	error code if no service is available.

+

+	* src/base/ftinit.c (FT_Done_FreeType): Change return value for

+

+	* src/base/ftobjs.c (FT_New_Size): Change return value for invalid

+	`asize' parameter to `Invalid_Argument'.

+

+	* src/base/ftoutln.c (FT_Outline_Copy): Change return value for

+	invalid `source' and `target' parameters to `Invalid_Outline'.

+

+2014-11-26  Werner Lemberg  <[email protected]>

+

+2014-11-25  Werner Lemberg  <[email protected]>

+

+	[Savannah bug #43682] Add/remove `void' casts to some functions.

+

+	We use a cast to indicate that we intentionally ignore a function's

+	return value.  However, this doesn't apply to API functions where

+	errors can only happen for trivially invalid input.

+

+	* src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder),

+

+

+	Don't cast cmap init function pointers to an incompatible type.

+

+	Without this patch, the number of parameters between declaration and

+	undefined behavior.

+

+	  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)

+	    6.5.2.2 Function calls

+	      9 If the function is defined with a type that is not

+	        the expression that denotes the called function, the

+

+	On certain platforms (c -> js with emscripten) this causes

+	implementation, function pointers of different types are stored in

+	[autofit] Fix Savannah bug #42148.

+

+	The adaptation of the cjk auto-hinter module to blue stringsets in

+	2013-08-25 had three severe bugs.  Mea culpa.

+

+	1. Contrary to the latin auto-hinter, characters for reference and

+	   overshoot values of a blue zone are specified separately.  Due to

+	   the screwed-up change it didn't work at all.

+

+	2. A boolean comparison was erroneously replaced with a cast,

+	   causing invalid results with the `^' operator later on.  The

+	   visual artifact caused by this problem is the topic of the bug

+	   report.

+

+	3. Two flag values were inverted, causing incorrect assignment of

+	   reference and overshoot values.

+

+	* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new

+	syntax to have both reference and overshoot characters in a single

+	string.  This is error #1.

+	Add extensive comments.

+

+	* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no

+	longer used.

+	(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.

+	This is error #3.

+

+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

+

+	* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.

+	Use character `|' to separate characters for reference and overshoot

+	values.

+	Improve tracing messages, synchronizing them with the latin

+	auto-hinter.

+	(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.

+	This is error #2.

+	(af_cjk_align_linked_edge): Add tracing message.

+

+	* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer

+

+	[autofit] Redesign the recognition algorithm of strong points.

+

+	In particular, local extrema without horizontal or vertical segments

+	are better recognized:

+

+	  + A                + D

+	   \                /

+	    \              /

+	     \            /

+	      \          /

+	       \        + C

+	        \    /

+	       B +/

+

+	If the distances AB and CD are large, point B wasn't previously

+	detected as an extremum since the `ft_corner_is_flat' function

+	`swallowed' BC regardless of its direction, tagging point B as weak.

+	The next iteration started at B and made `ft_corner_is_flat' swallow

+	point C, tagging it as weak also, et voilà.

+

+	To improve that, another pass gets now performed before calling

+	`ft_corner_is_flat' to improve the `topology' of an outline: A

+	sequence of non-horizontal or non-vertical vectors that point into

+	the same quadrant are handled as a single, large vector.

+

+	Additionally, distances of near points are now accumulated, which

+	makes the auto-hinter handle them as if they were prepended to the

+	next non-near vector.

+

+	This generally improves the auto-hinter's rendering results.

+

+	* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.

+

+	* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag

+	`AF_FLAG_NEAR'.

+

+	[autofit] Improve scoring algorithm for identifying stems.

+

+	Problem reported by Karsten Lücke <[email protected]>.

+

+	The new algorithm takes care of the width of stems: If the distance

+	between two segments is larger than the largest stem width, the

+	demerits quickly increase for larger distances.  This improves

+	hinting of slanted fonts (especially if the inner parts of serifs

+	have non-horizontal `shoulders'), avoiding false stem links.

+

+	* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest

+

+	* builds/unix/configure.raw: Use `x"${xxx}" != xno' style.

+

+2014-03-04  Werner Lemberg  <[email protected]>

+

+	Minor fix for `make devel'.

+

+	* builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use

+	pkg-config for bzip2 since not all GNU/Linux distributions have

+	`bzip2.pc' (and the header file `bzlib.h' is located in /usr/include

+	normally).

+

+2014-03-04  Sean McBride  <[email protected]>

+

+2014-03-03  Werner Lemberg  <[email protected]>

+

+	Rewrite library option handling in `configure'.

+

+	o Introduce `auto' value for `--with-XXX' library options; this is

+	  now the default.

+

+	o First use `pkg-config' for library detection, then fall back to

+	  other tests.

+

+	* builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,

+	--with-harfbuzz): Rewrite.

+	Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'

+	variables to collect data for `freetype2.pc' and `freetype-config'.

+	option.

+	(libs): Updated.

+	(staticlibs): New variable, to be used if `--static' is given.

+	* docs/freetype-config.1: Document `--static'.

+

+	* builds/unix/freetype2.in, builds/unix/unix-def.in: Updated.

+

+2014-03-01  Werner Lemberg  <[email protected]>

+

+	Avoid `long long' warnings with older gcc compilers.

+	Problem reported by Hin-Tak Leung <[email protected]>.

+

+	* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for

+	versions < 4.6.  This is especially needed for Max OS X since this

+	OS runs a gcc variant (or emulation) based on version 4.2.1.

+

+2014-03-01  Werner Lemberg  <[email protected]>

+

+	* docs/INSTALL.CROSS: Revised and updated.

+

+2014-03-01  Werner Lemberg  <[email protected]>

+

+	Make `make clean' remove `freetype2.pc'.

+

+	This is a generated file at build time, not configure time.

+

+	* builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...

+	(CLEAN): This variable.

+

+2014-03-01  Werner Lemberg  <[email protected]>

+

+	* builds/unix/configure.raw (HAVE_PKG): New variable.

+	* builds/unix/freetype-config.in, builds/unix/freetype2.in,

+	builds/unix/unix-def.in (freetype-config, freetype2.pc): Handle

+	HarfBuzz.

+

+	* docs/INSTALL.UNIX: Document interdependency of FreeType with

+	HarfBuzz.

+

+2014-02-28  Alexei Podtelezhnikov  <[email protected]>

+

+	[cff] Math simplifications.

+

+	* src/cf2blues.c (cf2_blues_init): Use `FT_MulDiv'.

+	* src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division.

+

+2014-02-28  Dave Arnold  <[email protected]>

+

+	[cff] Fix Savannah bug #41697, part 2.

+

+	* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,

+	cf2_initGlobalRegionBuffer): It is possible for a charstring to call

+	a subroutine if no subroutines exist.  This is an error but should

+	not trigger an assert.  Split the assert to account for this.

+

+2014-02-28  Dave Arnold  <[email protected]>

+

+	[cff] Fix Savannah bug #41697, part 1.

+

+	* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is

+	invalid.  In this case, it is not safe to use the length of

+	`hStemHintArray'; the exception has already been recorded in

+	`hintMask'.

+

+2014-02-26  Werner Lemberg  <[email protected]>

+

+	[sfnt] Fix Savannah bug #41696.

+

+	* src/sfnt/ttcmap.c (tt_cmap0_validate, tt_cmap2_validate,

+	tt_cmap4_validate, tt_cmap14_validate): Fix limit tests.

+

+	* src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.

+

+2014-02-26  Werner Lemberg  <[email protected]>

+

+	[bdf] Fix Savannah bug #41692.

+

+	bdflib puts data from the input stream into a buffer in chunks of

+	1024 bytes.  The data itself gets then parsed line by line, simply

+	increasing the current pointer into the buffer; if the search for

+	the final newline character exceeds the buffer size, more data gets

+	read.

+

+	However, in case the current line's end is very near to the buffer

+	end, and the keyword to compare with is longer than the current

+	line's length, an out-of-bounds read might happen since `memcmp'

+	doesn't stop properly at the string end.

+

+	* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons

+	stop at string ends.

+

+2014-02-17  suzuki toshiya  <[email protected]>

+

+	[autofit] Fix `make multi' compilation.

+

+	* src/autofit/hbshim.c: Include `afglobal.h' and `aftypes.h'.

+	`windows'.

+

+	* builds/windows/detect.mk, builds/windows/win32-def.mk:

+	introduced in Perl version 5.10.

+

+2014-02-04  Werner Lemberg  <[email protected]>

+

+	Fix compilation with MinGW.

+

+	Right now, compilation out of the box with latest MinGW is broken

+	cf.

+

+

+2014-01-26  Werner Lemberg  <[email protected]>

+

+	[autofit] Introduce two more slots for standard characters.

+

+	features that mainly operate on numerals.

+

+	* src/autofit/afscript.h: Add more standard characters.

+

+	[autofit] Fix Indic scripts.

+

+	Split the single, incorrect Indic entry into separate scripts so

+	that the covered ranges are the same: Bengali, Devanagari, Gujarati,

+	Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,

+	Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove

+	entries for Meetei Mayek and Sharada – the Unicode ranges were

+	incorrect (and nobody has complained about that), fonts are scarce

+	for those scripts, and the Indic auto-hinter support is rudimentary

+	anyways.

+

+	* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and

+	AF_CONFIG_OPTION_CJK.

+

+	* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.

+	Use it, together with AF_CONFIG_OPTION_INDIC and

+	AF_CONFIG_OPTION_CJK, to update.

+

+	* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.

+	[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.

+	Sort entries by tags.

+	`af_get_coverage', reject glyphs which are not substituted.

+

+2014-01-03  Werner Lemberg  <[email protected]>

+

+	[autofit] Fix handling of default coverages.

+

+	With this commit, the implementation of coverage handling is

+	completed.

+

+	* src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to

+	do.

+	Reject coverages which don't contain appropriate glyphs for blue

+	zones.

+

+2014-01-03  Werner Lemberg  <[email protected]>

+

+	[autofit] Fix handling of default coverages.

+

+

+2014-01-03  Werner Lemberg  <[email protected]>

+

+	[autofit] Fix scaling of HarfBuzz shaping.

+

+	[autofit] Add more styles.

+

+	* src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New

+	auxiliary macros; use them to define styles for Cyrillic, Greek, and

+	Latin.

+

+	* src/autofit/afcover.h: Remove coverage for oldstyle figures.

+	Since those digits are used in combination with ordinary letters, it

+	makes no sense to handle them separately.

+

+	* src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit

+	`options' parameter to 4 bits.

+

+2014-01-01  Werner Lemberg  <[email protected]>

+

+	[autofit] Don't combine multiple features into one set.

+

+	Combining them, as originally envisioned, would lead to much more

+	complicated code, as investigations have shown meanwhile.  The major

+	drawback is that we run out of available style slots much earlier.

+	However, this is only a theoretical issue since we don't support a

+	large number of scripts currently.

+

+	[ftrfork] Fix the face order difference between POSIX and Carbon.

+

+	The fragmented resources in Suitcase and .dfont should be reordered

+	when `POST' resource for Type1 is being restored, but reordering of

+	sfnt resources induces the different face order.  Now the ordering

+	is restricted to `POST' resource only, to prevent the different

+	order issue (e.g. the face index in the fontconfig cache generated

+	with Carbon framework is incompatible with that by FreeType 2

+	without Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

+

+	[autofit] Introduce `coverages'.

+

+	Coverages are the interface to the HarfBuzz library to access

+	OpenType features for handling glyphs not addressable by the cmap.

+

+	Right now, compilation of HarfBuzz is only added to the development

+	build.  A solution for standard build mode will be delayed until

+	HarfBuzz gets split into two libraries to avoid mutual dependencies

+	between FreeType and HarfBuzz.

+

+	Note that this is only a first step in handling coverages, basically

+	providing the framework only.  Code for handling selected OpenType

+	features (this is, actually using the data in `afcover.h') will

+	follow.

+

+2013-11-13  Werner Lemberg  <[email protected]>

+

+	Simplify header file hierarchy.

+

+	This large patch changes the header file directory layout from

+	`include/freetype/...' to `include/...', effectively removing one

+	level.  Since the file `ft2build.h' is also located in `include'

+	(and it stays there even after installation), all FreeType header

+	files are now in a single directory.

+

+	Applications that use (a) `freetype-config' or FreeType's

+	`pkg-config' file to get the include directory for the compiler, and

+	(b) the documented way for header inclusion like

+

+	  #include <ft2build.h>

+	  #include FT_FREETYPE_H

+	  ...

+

+	don't need any change to the source code.

+	* builds/unix/install.mk (install): No longer try to remove `cache'

+	and `internal' subdirectories; instead, remove the `freetype'

+	subdirectory.

+2013-11-01  Werner Lemberg  <[email protected]>

+

+	[truetype] Minor code refactoring.

+

+	Two benefits: The allocated FDEF (and IDEF) array gets slightly

+	smaller, and the `ttdebug' demo program has access to function

+	numbers without additional costs.

+

+	Fortunately, no changes to FontForge are necessary – this is the

+	only external TrueType debugger I know of, but others may exist and

+	should check the code accordingly.

+

+	* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and

+

+	* src/sfnt/ttload.c (tt_face_load_os2): Implement it.

+

+

+	[arm] Fix thumb2 inline assembly under LLVM.

+

+	When using `ADD' with an immediate operand, the instruction is

+	actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the

+	immediate operand cannot exceed 4095.  It will fail to compile with

+	LLVM.

+

+

+2013-10-03  Dave Arnold  <[email protected]>

+

+	* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.

+

+	Note that the old code avoided using a region of the piecewise

+	linear function where the slope was zero.  The recovery was to use a

+	different section of the function, which produced a different,

+	incorrect amount of darkening.

+

+

+	* src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.

+

+2013-10-02  Dave Arnold  <[email protected]>

+

+	* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.

+

+	This line was lost in commit 89ca1fd6 (from 2013-06-25).  The effect

+	is to use a previous darkening amount when producing an unhinted,

+	unscaled outline.  This can cause autohint samples in ftgrid and

+	ftview to be based on darkened CFF outlines instead of unhinted,

+	undarkened ones.

+

+2013-09-29  Dave Arnold  <[email protected]>

+

+	Fix Savannah bug #39295.

+

+	The bug was caused by switching to the initial hintmap (the one in

+	effect when `moveto' executes) just before drawing the final element

+	in the charstring.  This ensured that the path was closed (in both

+	Character Space and Device Space).  But if the final element was a

+	curve and if the final hintmap was different enough from the initial

+	one, then the curve was visibly distorted.

+

+	The first part of the fix is to draw the final curve using the final

+	hintmap as specified by the charstring.  This corrects the

+	distortion but does not ensure closing in Device Space.  It may

+	require the rasterizer to automatically generate an extra closing

+	line.  Depending on the hintmap differences, this line could be from

+	zero to a couple pixels in length.

+

+	The second part of the fix covers the case where the charstring

+	subpath is closed with an explicit line.  We now modify that line's

+	end point to avoid the distortion.

+

+	Some glyphs in the bug report font (TexGyreHeros-Regular) that show

+	the change are:

+

+	  25ppem    S (98)

+	  24ppem    eight (52)

+	  25.5ppem  p (85)

+

+	Curves at the *end* of a subpath are no longer distorted.  However,

+	some of these glyphs have bad hint substitutions in the middle of a

+	subpath, and these are not affected.

+

+	The patch has been tested with a set of 106 fonts that shipped with

+	Adobe Creative Suite 4, together with 756 Open Source CFF fonts from

+	Google Fonts.  There are 1.5 million glyphs, of which some 20k are

+	changed with the fix.  A sampling of a few hundred of these changes

+	have been examined more closely, and the changes look good (or at

+	least acceptable).

+

+	* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'

+	to indicate that we synthesize a closepath line.

+

+	* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.

+	(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for

+	`lineto' operator) and adjust hint zone.

+	For synthesized closing lines, use end point in first hint zone.

+	(cf2_glyphpath_lineTo): Take care of synthesized closing lines.  In

+	particular, shift the detection of zero-length lines from character

+	space to device space.

+	(cf2_glyphpath_closeOpenPath): Remove assertion.

+	Updated.

+

+	[autofit] Introduce data file for blue strings.

+

+	The idea is to have a central file which gets processed by a Perl

+	script to create proper `.c' and `.h' files using templates.  There

+	are two other reasons to do that:

+

+	  . The data file should be easily readable.  We use UTF-8 encoding

+	    which then gets converted to single bytes.

+

+	  . Since the number of supported scripts will increase soon, the

+	    current usage of blue string arrays is a waste of space.  Using

+	    the Perl script it is possible to imitate jagged arrays,

+	    defining enumeration constants as offsets into the arrays.

+

+	This commit only adds files without changing any functionality.

+

+	* src/autofit/afblue.dat: New data file.

+	* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

+

+	Speed up ARMv7 support.

+

+	When building for ARMv7 with thumb2 instructions, the optimized

+	`FT_MulFix_arm' assembly routine was not being used.

+

+	The reason for this is in the `ftconfig.h' header, namely:

+

+	- The assembly routine uses the `smull' instruction which is not

+	  available when generating Thumb-1 machine code.  It is available

+	  in Thumb-2 mode, though.

+

+	- The header was written a long time ago before Thumb-2 became

+	  widely popular (e.g. with Android).  So it simply doesn't use the

+	  assembly routine if the `__thumb__' built-in macro is defined.

+

+	- When compiling in Thumb-2 mode, the compiler will define both

+	  `__thumb__' and `__thumb2__'.

+

+	By checking for `(__thumb2__ || !__thumb__)', we ensure that the

+	assembly routine is only avoided when generating Thumb-1 code.

+

+	Given that this is performance-sensitive function, this improves

+	`ftbench' as follows on a Galaxy Nexus:

+2013-06-04  Werner Lemberg  <[email protected]>

+

+	Apply fixes for cppcheck nitpicks.

+

+	  https://cppcheck.sourceforge.net/

+

+	The call was (from the top-level of the FreeType tree):

+

+	  cppcheck --force \

+	           --enable=all \

+	           -I include \

+	           -I include/freetype/ \

+	           -I include/freetype/config/ \

+	           -I include/freetype/internal/ \

+	           . &> cppcheck.log

+

+	Note that the current version heavily chokes on FreeType, delivering

+	many wrong results.  I will report those issues to the cppcheck team

+	so that a newer version gives improved results hopefully.

+

+	*/* Improve variable scopes.

+	*/* Remove redundant initializations which get overwritten.

+

+	* src/base/ftmac.c, builds/mac/ftmac.c (count_faces_scalable):

+	Remove unused variable.

+

+	* src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero.

+

+	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate):

+	Remove functionless code.

+

+	* src/tools/ftrandom.c (main): Fix memory leak.

+

+2013-06-03  Werner Lemberg  <[email protected]>

+

+	Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option.

+

+	This controls whether the old FreeType CFF engine gets compiled into

+	FreeType.  It is now disabled by default.

+

+	* devel/ftoption.h, include/freetype/config/ftoption.h

+	(CFF_CONFIG_OPTION_OLD_ENGINE): New macro.

+

+	* src/cff/cffdrivr.c (cff_property_set), src/cff/cffgload.c

+	(CFF_Operator, cff_argument_counts, cff_builder_add_point,

+	cff_operator_seac, cff_decoder_parse_charstrings, cff_slot_load),

+	src/cff/cffgload.h, src/cff/cffobjs.c (cff_driver_init): Use

+	CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code.

+

+	* docs/CHANGES: Updated.

+

+2013-06-02  Werner Lemberg  <[email protected]>

+

+	Fix PNG library handling.

+

+	* builds/unix/configure.raw: Don't use LIBPNG_LIBS but

+	LIBPNG_LDFLAGS.

+

+2013-05-23  Behdad Esfahbod  <[email protected]>

+

+	Add support for color embedded bitmaps (eg. color emoji).

+

+	A new load flag, FT_LOAD_COLOR, makes FreeType load color

+	embedded-bitmaps, following this draft specification

+

+	  https://color-emoji.googlecode.com/git/specification/v1.html

+

+	which defines two new SFNT tables, `CBDT' and `CBLC' (named and

+	modeled after `EBDT' and `EBLC', respectively).  The color bitmaps

+	are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA

+	pre-multiplied sRGB images.  If PNG support is available, PNG color

+	images as defined in the same proposed specification are supported

+	also.

+

+	Note that color bitmaps are converted to grayscale if client didn't

+	ask for color.

+

+	* builds/unix/configure.raw: Search for libpng.

+	Add `--without-png' option.

+

+	* devel/ftoption.h, include/freetype/config/ftoption.h

+	(FT_CONFIG_OPTION_USE_PNG): New macro.

+

+	* src/sfnt/pngshim.c, src/sfnt/pngshim.h: New files.

+

+	* src/sfnt/sfnt.c: Include `pngshim.c'.

+

+	* src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h'

+	(tt_face_load_eblc): Load `CBLC'.

+	(tt_sbit_decoder_init): Load `CBDT'.

+	(tt_sbit_decoder_alloc_bitmap): Pass load flags to select between

+	color and grayscale bitmaps.

+	Set `num_grays'.  This is used by `ftview' to choose the blending

+	algorithm.

+	(tt_sbit_decoder_load_byte_aligned,

+	tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound,

+	tt_sbit_decoder_load_image): Pass load flag.

+	s/write/pwrite/.

+	Don't call `tt_sbit_decoder_alloc_bitmap'.

+	Updated.

+	(tt_sbit_decoder_load_bitmap): Pass load flag.

+	Handle new glyph formats 17, 18, and 19.

+	Call `tt_sbit_decoder_alloc_bitmap'.

+	Flatten color bitmaps if necessary.

+	(tt_face_load_sbit_image): Updated.

+

+	* src/sfnt/rules.mk (SFNT_DRV_SRC): Add `pngshim.c'.

+

+	* docs/CHANGES: Updated.

+

+	Make `apinames' create an import file for NetWare.

+

+	* src/tools/apinames.c (PROGRAM_VERSION): Set to 0.2.

+	(OutputFormat): Add `OUTPUT_NETWARE_IMP'.

+	(names_dump): Handle it.

+	(usage): Updated.

+	(main): Handle new command line flag `-wN'.

+

+2013-05-23  Behdad Esfahbod  <[email protected]>

+2016-07-08  Alexei Podtelezhnikov  <[email protected]>

+

+	[smooth] Sub-banding protocol revision.

+

+	Rasterization sub-banding is utilized at large sizes while using a

+	rather small fixed memory pool.  Indeed it is possible to make an

+	educated guess how much memory is necessary at a given size for a

+	given glyph.  It turns out that, for a large majority of European

+	glyphs, you should store about 8 times more boundary pixels than

+	their height.  Or, vice versa, if your memory pool can hold 800

+	pixels the band height should be 100 and you should sub-band

+	anything larger than that.  Should you still run out of memory,

+	FreeType bisects the band but you have wasted some time.  This is

+	what has been implemented in FreeType since the beginning.

+

+	It was overlooked, however, that the top band could grow to twice

+	the default band size leading to unnecessary memory overflows there.

+	This commit fixes that.  Now the bands are distributed more evenly

+	and cannot exceed the default size.

+

+	Now the magic number 8 is really suitable for rather simple European

+	scripts.  For complex Chinese logograms the magic number should be

+	13 but that is subject for another day.

+

+	* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding

+	protocol.

+

+2016-07-07  suzuki toshiya  <[email protected]>

+

+	[mac] Fix Savannah bug #48417.

+

+	Mac OS X linker throws errors when `-exported_symbol_list' input

+	file includes non-existing symbols.  Reported by Ryan Schmidt.

+

+	* builds/exports.mk: Exclude ftmac.h from the headers for apinames

+	by default.  Include it when ftmac.c would be compiled.

+

+2016-07-06  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttinterp.c (TInstruction_Function): Removed, unused.

+

+2016-07-04  Werner Lemberg  <[email protected]>

+

+	[autofit] Handle single-point contours as segments.

+

+	Doing so allows us to link them to edges – some fonts like

+	`NotoSansGurmukhi-Regular' have such isolated points sitting exactly

+	on other outlines.

+

+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't

+	ignore one-point contours but handle them specially as one-point

+	segments.

+

+2016-07-01  Alexei Podtelezhnikov  <[email protected]>

+

+	[smooth] Variable type revision (part 1).

+

+

+	[autofit] Add support for Georgian scripts.

+

+	Georgian is problematic, since `uppercase' forms of Mkhedruli

+	(called Mtavruli) are not yet defined in Unicode, which means that

+	proper blue zones can't be defined.  However, there is already a

+	proposal submitted to Unicode; see

+

+	  https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf

+

+	Additionally, due to historical reasons, Unicode treats Khutsuri as

+	the same script as Mkhedruli, and so does OpenType.  However, since

+	the two scripts have completely different shapes it can happen that

+	blue zones differ considerably.  The tag `geok' used here (derived

+	from ISO 15924) to differentiate the two scripts is not an OpenType

+	tag in use.  If we now have a font that contains both glyphs for

+	Mkhedruli and Khutsuri, and it uses OpenType features for both also,

+	HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,

+	blue zones for `geok' are not used for glyphs involved in the

+	OpenType features.

+

+	An issue not yet resolved is which OpenType feature should be used

+	to access Mtavruli glyph shapes; right now, FreeType doesn't set up

+	support for them, but it is easy to add them later on as soon as

+	more information is available.

+

+	[pfr] Robustify bitmap strike handling (#47514).

+

+	We did a binary search for a charcode without ensuring that the

+

+	[autofit] Fix handling of default script.

+

+	Patch taken from ttfautohint, commit

+	071ae2c00e0d67f9d19418f4fade1c23d27dc185.

+

+	There were two bugs.

+

+	  - We now use non-standard script tags like `khms' for special

+	    purposes.  However, HarfBuzz maps such tags to `DFLT', and

+	    without this commit the associated lookups were incorrectly

+	    assigned to the non-standard tags.

+

+	  - Let's assume we have a Bengali font, and the font's `DFLT'

+	    script tag handles the necessary lookups for Bengali, too.

+	    Without this commit, the `DFLT' lookups were assigned to

+	    ttfautohint's default script (usually `latn') before the

+	    standard lookups for Bengali were handled.

+

+	    We now have the following order while searching for covered

+	    glyph indices.

+

+	      special features of scripts (e.g. `sups' for Cyrillic)

+	      Unicode mappings of scripts

+	      remaining features of scripts (especially important for Indic

+	        scripts)

+	      default features of default script

+

+	* src/autofit/afshaper.c, src/autofit/afshaper.h

+	(af_shaper_get_coverage): Add boolean parameter to indicate default

+	script.

+	Update all callers.

+

+	* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):

+	Fix search order for coverages.

+

+	- Duplicate table entries (this is, having the same tag) were not

+

+	- The number of valid tables was sometimes too large, leading to

+	  access of invalid tables.

+

+	[autofit] Redesign code ranges (1/2).

+

+	This patch introduces auxiliary code ranges that identify no-base

+	characters; they refer to glyphs of a script that should be hinted

+	without alignments to blue zones (mostly diacritics).

+

+	It also splits off ranges for fallback scripts that handle subscript

+	and superscript characters not covered by OpenType features.  For

+	example, this greatly helps improve the hinting of various phonetic

+	alphabets, which contain a large amount characters that look like

+	superscript glyphs.

+

+	Finally, code ranges are updated to Unicode 8.0, and enclosed

+	characters are removed in general since they normally look better if

+	they stay unhinted.

+

+	* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode

+	8.0.

+	Split off superscript-like and subscript-like glyphs into...

+

+	(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.

+

+	(af_xxxx_nobase_uniranges): New arrays that hold no-base characters

+	of the corresponding character ranges.

+

+	We no longer `pollute' the namespace of possible header file names;

+

+	there is an example code to trigger the bug.

+

+2015-06-02  Werner Lemberg  <[email protected]>

+

+

+2015-05-31  Werner Lemberg  <[email protected]>

+

+	[truetype] In GX, make private point numbers work correctly.

+

+	This is completely missing in Apple's documentation: If a `gvar'

+	tuple uses private point numbers (this is, deltas are specified for

+	some points only), the uncovered points must be interpolated for

+	this tuple similar to the IUP bytecode instruction.  Examples that

+	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.

+

+	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,

+	tt_handle_deltas): New functions.

+	(TT_Vary_Get_Glyph_Deltas): Renamed to...

+	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the

+	points and does no longer return an array of deltas.

+	Add tracing information.

+	Call `tt_handle_deltas' to interpolate missing deltas.

+	Also fix a minor memory leak in case of error.

+

+	* src/truetype/ttgxvar.h: Updated.

+

+	* src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code

+

+	[truetype] Fix return values of GETINFO bytecode instruction.

+	`vertical_lcd' and `gray_cleartype'.

+

+	* src/truetype/ttgload.c (tt_loader_init): Initialize new fields.

+	Change `symmetrical smoothing' to TRUE, since FreeType produces

+	exactly this.

+

+	* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit

+	values for symmetrical smoothing, namely 11/18.

+	Handle bits for vertical LCD subpixels (8/15) and Gray ClearType

+	(12/19).

+

+2015-05-23  Werner Lemberg  <[email protected]>

+

+	[truetype] Minor.

+

+	* src/truetype/ttinterp.h (TT_ExecContext):

+	 s/subpixel/subpixel_hinting.

+

+	* src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.

+

+2015-05-22  Werner Lemberg  <[email protected]>

+

+	[truetype] Support selector index 3 of the INSTCTRL instruction.

+

+	This flag activates `native ClearType hinting', disabling backward

+	compatibility mode as described in Greg Hitchcocks whitepaper.  In

+	other words, it enables unrestricted functionality of all TrueType

+	instructions in ClearType.

+

+	* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'

+	unconditionally.

+	(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of

+	`GS.instruct_control' is active.

+

+	* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.

+	(Ins_GETINFO): Updated.

+2015-05-20  Werner Lemberg  <[email protected]>

+

+

+	* src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'

+	argument.

+

+2015-05-17  Werner Lemberg  <[email protected]>

+

+	[truetype] Fix loading of composite glyphs.

+

+	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the

+	ARGS_ARE_XY_VALUES flag is not set, handle argument values as

+	unsigned.  I trust `ttx' (which has exactly such code) that it does

+	the right thing here...

+

+	The reason that noone has ever noticed this bug is probably the fact

+	that point-aligned subglyphs are rare, as are subglyphs with a

+	number of points in the range [128;255], which is quite large (or

+	even in the range [32768;65535], which is extremely unlikely).

+

+2015-05-12  Chris Liddell  <[email protected]>

+

+	[cff] Make the `*curveto' operators more tolerant.

+

+	* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes

+	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,

+	pulling values off the stack until the stack is exhausted.

+	Implicitly the stack must be a multiple (or for subtly different

+	behaviour) a multiple plus a specific number of extra values deep.

+	If that's not the case, enforce it (as the old code did).

+

+2015-05-12  Chris Liddell  <[email protected]>

+

+	[cff] fix incremental interface with new cff code.

+

+	* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental

+	interface to retrieve glyph data for a SEAC, it be left to the

+	incremental interface callback to apply the encoding to raw

+	character index (as it was in the previous code).

+	divisions.

+

+2015-04-28  Werner Lemberg  <[email protected]>

+

+	[cff] Use `name' table for PS name if we have a SFNT-CFF.

+

+	This follows the OpenType 1.7 specification.  See

+

+	  https://tug.org/pipermail/tex-live/2015-April/036634.html

+

+	for a discussion.

+

+	[autofit] Reuse slot glyph loader.

+

+	No need to create a new glyph loader; we can reuse the one from

+	`slot->internal->loader'.  It's hard to tell why it was written that

+	way originally, but new code looks sound and correct to me, and

+	avoids lots of allocations.

+

+

+2015-01-14  Behdad Esfahbod  <[email protected]>

+

+	[autofit] Remove (unused) support for composite glyphs.

+

+	We never have to deal with composite glyphs in the autohinter, as

+	those will be loaded into FORMAT_OUTLINE by the recursed

+	`FT_Load_Glyph' function.

+

+	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply

+	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies

+	FT_LOAD_NO_HINTING:

+

+	  /* resolve load flags dependencies */

+

+	  if ( load_flags & FT_LOAD_NO_RECURSE )

+	    load_flags |= FT_LOAD_NO_SCALE         |

+	                  FT_LOAD_IGNORE_TRANSFORM;

+

+	  if ( load_flags & FT_LOAD_NO_SCALE )

+	  {

+	    load_flags |= FT_LOAD_NO_HINTING |

+	                  FT_LOAD_NO_BITMAP;

+

+	    load_flags &= ~FT_LOAD_RENDER;

+	  }

+

+	and as such the auto-hinter is never called.  Thus, the recursion in

+	`af_loader_load_g' never actually happens.  So remove the depth

+	counter as well.

+

+	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'

+	parameter.

+	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.

+	(af_loader_load_glyph): Updated.

+

+	[raster] Fix uninitialized memory access.

+

+	Apparently `ras.cProfile' might be uninitialized.  This will be the

+	case if `ras.top == ras.cProfile->offset', as can be seen in

+	`End_Profile'.  The overshoot code introduced in a change `Fix B/W

+	rasterization of subglyphs with different drop-out modes.' (from

+	2009-06-18) violated this, accessing `ras.cProfile->flags'

+	unconditionally just before calling `End_Profile' (which then

+	detected that `cProfile' is uninitialized and didn't touch it).

+

+	This was harmless, and was not detected by valgrind before because

+	the objects were allocated on the `raster_pool', which was always

+	initialized.  With recent change to allocate raster buffers on the

+	stack, valgrind now reported this invalid access.

+

+	* src/raster/ftraster.c (Convert_Glyph): Don't access an

+	uninitialized `cProfile'.

+

+2015-01-14  Behdad Esfahbod  <[email protected]>

+

+	[smooth] Fix uninitialized memory access.

+

+	Looks like `ras.span_y' could always be used without initialization.

+	This was never detected by valgrind before because the library-wide

+	`raster_pool' was used for the worker object and `raster_pool' was

+	originally zero'ed.  But subsequent reuses of it were using `span_y'

+	uninitialized.  With the recent change to not use `render_pool' and

+	allocate worker and buffer on the stack, valgrind now detects this

+	uninitialized access.

+

+	* src/smooth/ftgrays.c (gray_raster_render): Initialize

+	`ras.span_y'.

+	With this patch, rasterizing glyphs from different faces from

+	different threads doesn't fail choosing rasterizer

+	strikes in advance.

+

+	Reported as

+

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353

+

+

+	[truetype] Fix linear metrics of GX variation fonts (#49829).

+

+	When asking for an unhinted non-default variations,

+	`linearVertAdvance' is currently the value from the `hmtx' table

+	instead of the actual value after applying the variation.  `HVAR'

+	support fixes this, but fonts will exist without that table and will

+	Reported as

+

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=304

+

+	* src/base/ftobjs.c (FT_Open_Face): Code moved to...

+	(ft_open_face_internal): ... this function.

+	Add a parameter to control whether we try special Mac font handling

+	in case of failure.

+	(FT_Open_Face, FT_New_Face, FT_New_Memory_Face,

+	This is better behaviour than exiting with an error.

+

+	* include/freetype/internal/tttypes.h (TT_Face): Add `use_fvar'

+	field.

+

+	* src/sfnt/sfobjs.c (sfnt_init_face): Compute `use_fvar', also

+

+

+	* src/cff/cffload.c (cff_font_load): Pure CFFs don't have a

+	[cff] Implement CFF2 support (2/2).

+

+	The font variation code.  All parts dependent on the GX code in the

+	`truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.

+	In other words, you can still compile the `cff' module without

+	support without font variation).

+

+

+	Building FreeType with external zlib 1.2.8 makes msvc 14 stop with

+	the following error.

+

+	  ftgzip.c

+	  zlib-1.2.8\zlib.h(86): error C2061:

+	                          error count exceeds 100; stopping compilation

+

+	The error happens because FreeType keeps an own copy of zlib-1.1.4

+	under `src/gzip'.  When building `src/gzip/ftgzip.c' with

+	FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses

+

+	  #include <zlib.h>

+

+	which correctly finds an external `zlib.h', but `zlib.h' itself has

+	a line

+	  #include "zconf.h"

+

+	compiling the files in `src/gzip'.

+	* src/gzip/ftzconf.h: ... this.

+

+	  https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch

+

+	Prepend the foundry name plus a space to the family name.  There are

+	many fonts just called `Fixed' which look completely different, and

+	which have nothing to do with each other.  When selecting `Fixed' in

+	KDE or Gnome one gets results that appear rather random, the style

+	changes often if one changes the size and one cannot select some

+	fonts at all.

+

+	We also check whether we have `wide' characters; all put together,

+	we get family names like `Sony Fixed' or `Misc Fixed Wide'.

+

+	[truetype] Sanitize only last entry of `loca' table.

+

+	Without this patch, a loca sequence like `0 100000 0 100000 ...',

+	where value 100000 is larger than the `glyf' table size, makes

+	FreeType handle the whole `glyf' table as a single glyph again and

+

+	[smooth] Simplify span rendering more.

+

+	It turns out that there is significant cost associated with `FT_Span'

+

+	[sfnt] Cache offset and size to bitmap data table.

+

+	This commit avoids `EBDT' and friends being looked up again and

+	again while loading a single embedded bitmap.

+

+	* include/freetype/internal/tttypes.h (TT_FaceRec)

+	[TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and

+

+	* include/freetype/internal/ftdriver.h: Remove unused typedefs.

+

+2016-08-22  Alexei Podtelezhnikov  <[email protected]>

+

+	[smooth] Simplify span rendering.

+

+	This removes unnecessary complexity of span merging and buffering.

+	Instead, the spans are rendered as they come, speeding up the

+	rendering by about 5% as a result.

+

+	* src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed.

+

+	* src/sfnt/ttload.c (tt_face_load_post): Fix types.

+

+2016-08-06  Jon Spencer  <[email protected]>

+

+	[sfnt] Fix `FT_Get_Advance' for bitmap strikes.

+

+	`FT_Get_Advance' returns 0 for bitmap fonts.  It first gets the

+	advance value from the font table and then scales it by the

+	`font->size->metrics->x_scale' field.  But `FT_Select_Size' doesn't

+	set that value for bitmap fonts and the advance gets scaled to zero.

+

+	Taken from

+

+	  https://github.com/behdad/harfbuzz/issues/252

+

+	* src/sfnt/ttsbit.c (tt_face_load_strike_metrics)

+	<TT_SBIT_TABLE_TYPE_EBLC>: Set scale values.

+

+2016-08-06  Behdad Esfahbod  <[email protected]>

+

+	[truetype] Fix GX variation handling of composites.

+

+	* src/truetype/ttgload.c (load_truetype_glyph)

+	[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check `ARGS_ARE_XY_VALUES' flag.

+

+2016-08-05  Alexei Podtelezhnikov  <[email protected]>

+

+	[smooth] Minor refactoring.

+

+	* src/smooth/ftgrays.c (gray_render_scanline, gray_render_line):

+	Updated.

+

+2016-07-29  Werner Lemberg  <[email protected]>

+

+	[sfnt, truetype] Don't abort on invalid `maxComponentDepth'.

+

+	Since 2016-05-16 we detect infinite recursion directly.

+

+	* src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust

+	`maxComponentDepth'.

+	* src/truetype/ttgload.c (load_truetype_glyph): Don't abort if

+	`maxComponentDepth' is not valid.  Instead, simply adjust its value

+	and emit a tracing message.

+

+2016-07-26  Werner Lemberg  <[email protected]>

+

+	* src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor.

+

+	No functional change.

+

+2016-07-22  Hin-Tak Leung  <[email protected]>

+

+	[truetype] Record the end of IDEFs.

+

+	To match the logic in FDEF.  The value of the end is only used for

+	bound-checking in `Ins_JMPR', so it may not have been obvious that

+	it was not recorded.  Tested (as part of Font Validator 2.0) all the

+	fonts on Fedora and did not see any change.

+

+	* src/truetype/ttinterp.c (Ins_IDEF): Updated.

+

+2016-07-19  Werner Lemberg  <[email protected]>

+

+	[truetype] Sanitizer fix, second try.

+

+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary

+	tests and use only one slot more.

+

+2016-07-19  Werner Lemberg  <[email protected]>

+

+	[truetype] Sanitizer fix.

+

+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array

+	to fix nested loops.

+

+2016-07-18  Werner Lemberg  <[email protected]>

+

+	[truetype] Make GETDATA work only for GX fonts.

+

+	* src/truetype/ttinterp.c (opcode_name): Updated.

+	(Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'.

+	(TT_RunIns): Updated.

+

+2016-07-17  Werner Lemberg  <[email protected]>

+

+	[truetype] Add support for Apple's

+

+	  GETDATA[], opcode 0x92

+

+	bytecode instruction.  It always returns 17, and we have absolutely

+	no idea what it is good for...

+

+	* src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.

+	(Ins_GETDATA): New function.

+	(TT_RunIns): Add it.

+

+2016-07-16  Werner Lemberg  <[email protected]>

+

+	[truetype] Add bytecode support for GX variation fonts.

+

+	This commit implements undocumented (but confirmed) stuff from

+	Apple's old bytecode engine.

+

+	  GETVARIATION[], opcode 0x91

+	    This opcode pushes normalized variation coordinates for all axes

+	    onto the stack (in 2.14 format).  Coordinate of first axis gets

+	    pushed first.

+

+	  GETINFO[], selector bit 3

+	    If GX variation support is enabled, bit 10 of the result is set

+	    to 1.

+

+	* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.

+	(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.

+	(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector

+	bit 3, checking support for variation glyph hinting.

+	(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function

+	to implement opcode 0x91.

+	(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.

+

+2016-07-16  Werner Lemberg  <[email protected]>

+

+	[truetype] Fix GETINFO bytecode instruction.

+

+	* src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for

+	stretching information.

+

+2016-07-16  Behdad Esfahbod  <[email protected]>

+

+	[truetype] Make all glyphs in `Zycon' GX font work.

+

+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary

+	tests.

+

+2016-07-16  Werner Lemberg  <[email protected]>

+

+	[truetype] Fix GX delta tracing.

+

+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace

+	relative point movements.

+

+2016-07-16  Behdad Esfahbod  <[email protected]>

+

+	[truetype] More fixes for GX.

+

+	This finally fixes the rendering of the cyclist and the lizard in

+	the `Zycon' font.

+

+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point

+	index is always cumulative.

+

+	(tt_handle_deltas): Rename to...

+	(tt_interpolate_deltas): ... This.

+	Add new parameter for output point array.

+	Update caller.

+

+	(TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds

+	the intermediate results of `tt_interpolate_deltas' that are to be

+	added to `outline->points'.

+

+2016-07-15  Werner Lemberg  <[email protected]>

+

+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.

+

+	`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.

+

+	Reported by Alexei.

+

+2016-07-16  Nikolaus Waxweiler  <[email protected]>

+

+	* src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.

+

+	Problem reported by Hin-Tak Leung.

+

+2016-07-15  Werner Lemberg  <[email protected]>

+

+	[autofit] Update and improve segment and edge tracing.

+

+	* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace

+	`delta' also.

+	Don't show first point of segment as a replacement for `pos'; this

+	is (a) misleading, since the difference to `pos' can be almost

+	arbitrarily large in corner cases, and (b) it is better to have all

+	segment data in font units instead of a single value given in output

+	space coordinates.

+	Improve layout.

+	(af_glyph_hints_dump_edges): Show px->units and units->px conversion

+	values for convenience.

+	Improve layout.

+

+2016-07-15  Werner Lemberg  <[email protected]>

+

+	[autofit] For edges, reject segments wider than 1px (#41334).

+

+	* src/autofit/afhints.h (AF_SegmentRec): New member `delta'.

+

+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute

+	`delta'.

+	(af_latin_hints_compute_edges): Reject segments with a delta larger

+	than 0.5px.

+

+

+	* include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.

+

+2016-07-14  Werner Lemberg  <[email protected]>

+

+	[sfnt] Fix `face_index' value in `FT_Face' for named instances.

+

+	* src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits.

+

+2016-07-14  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.

+

+2016-07-14  Behdad Esfahbod  <[email protected]>

+

+	[truetype] Fix gxvar delta interpolation.

+

+	The coordinates of the base font should be used for interpolation

+	purposes, NOT the current points (i.e., the result of accumulation

+	of previous deltas).

+

+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize

+	`points_org' before looping over all tuples.

+

+	[base] Remove a check for resource ID in the resource fork driver.

+

+	LastResort.dfont has a marginal resource ID 0xFFFF for sfnt

+	resource.  Inside Macintosh: More Macintosh Toolbox, `Resource IDs'

+	(1-46), tells that some IDs are reserved and should not be used.

+	FreeType2 just uses resource ID to sort the fragmented resource.

+	To accept the marginal fonts, the checking is removed.

+

+	* src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id

+	validity check, fix a trace message format.

+

+2017-09-08  suzuki toshiya  <[email protected]>

+

+	[sfnt, truetype] Register the tags for marginal fonts.

+

+	The first 32bit of standard TrueType variants is 0x00010000,

+	`OTTO', `ttcf', `true' or `typ1'.  2 marginal dfonts on legacy Mac

+	OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources

+	starting 0xA5 followed by `kbd' or `lst'.  Considering the following

+	data could be parsed as conventional TrueType fonts, the header

+	checking is updated to allow these tags.  It seems that recent Mac

+	OS X has already switched to normal TTF for these fonts.

+

+	See the discussion at

+	http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0

+

+	* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header

+	tags for Keyboard.dfont and LastResort.dfont.

+	* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource

+	starts with TTAG_0xA5kbd or TTAG_0xA5lst.

+	* src/truetype/ttobjs.c (tt_face_init): Accept the face with the

+	format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

+

+2017-09-05  Werner Lemberg  <[email protected]>

+

+	Fix multiple calls of `FT_Bitmap_Convert'.

+

+	The documentation of `FT_Bitmap_Convert' says that multiple calls do

+	proper reallocation of the target FT_Bitmap object.  However, this

+	failed for the sequence

+

+	  non-empty bitmap

+	  empty bitmap

+	  non-empty bitmap

+

+	Reason was that `FT_Bitmap_Convert' only reallocated the bitmap

+	buffer if it became too small; it didn't make the buffer smaller.

+	For an empty bitmap following a non-empty one, only the buffer

+	dimension got set to zero, without deallocation.  If the next call

+	was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was

+	triggered.

+

+	* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target

+	buffer to the correct size.

+

+	* docs/CHANGES: Document it.

+

+2017-09-05  Werner Lemberg  <[email protected]>

+

+	[bdf] Fix size and resolution handling.

+

+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if

+	`POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are

+	missing.

+

+	* docs/CHANGES: Document it.

+

+2017-08-25  Alexei Podtelezhnikov  <[email protected]>

+	(vector_shuffle): New macro to take care of a different built-in

+2017-08-22  Werner Lemberg  <[email protected]>

+

+	[base] Don't zero out allocated memory twice (#51816).

+

+	Patch applied from bug report.

+

+

+	[smooth] Harmony LCD rendering.

+

+	This is a new technology for LCD-optimized rendering. It capitalizes

+

+	Handle some integer overflow run-time errors (#46149, #48979).

+

+	This commit (mainly for 32bit CPUs) is the first of a series of

+	similar commits to handle known integer overflows.  Basically, all

+	of them are harmless, since they affect rendering of glyphs only,

+	not posing security threats.  It is expected that fuzzying will show

+	up more overflows, to be fixed in due course.

+

+	The idea is to mark places where overflows can occur, using macros

+	that simply cast to unsigned integers, because overflow arithmetic

+	is well defined in this case.  Doing so suppresses run-time errors

+	of sanitizers without adding computational overhead.

+

+	* include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT,

+

+	[cff] s/cf2_floatToFixed/cf2_doubleToFixed/.

+	warning because the macro itself uses `double' literals).

+

+	[smooth] Implement minimal dynamic padding for LCD filtering.

+

+	Extra bitmap padding for LCD filtering depends on the filter.  The

+	default 5-tap filter needs 2 extra subpixels.  The light 3-tap filter

+	needs only 1 extra subpixel.  This space could be already available

+	due to rounding.  In order to optimize the padding, we now expand

+	CBox for the given filter weights before rounding.

+

+	[autofit] Fix metrics computation.

+

+	Problem reported by Markus Trippelsdorf <[email protected]> and

+	Nikolaus Waxweiler <[email protected]>.

+

+	* src/base/ftobjs.c (FT_Request_Size): Trigger recomputation of

+	calls for a single face fail.

+

+2017-04-29  Werner Lemberg  <[email protected]>

+

+	* src/truetype/ttdriver.c (tt_size_request): Properly check `error'.

+

+	Reported by Earnestly <[email protected]> in

+

+	  https://lists.nongnu.org/archive/html/freetype/2017-04/msg00031.html

+

+2017-04-27  Werner Lemberg  <[email protected]>

+

+	Introduce AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option.

+

+	* include/freetype/config/ftoption.h

+	(AF_CONFIG_OPTION_TT_SIZE_METRICS): New option, commented out by

+	default.

+

+	* src/autofit/afloader.c (af_loader_load_glyph): Use

+	AF_CONFIG_OPTION_TT_SIZE_METRICS to guard the corresponding code.

+

+2017-04-26  Werner Lemberg  <[email protected]>

+

+	* include/freetype/freetype.h (FT_Render_Mode): Fix order.

+

+

+2017-04-22  Werner Lemberg  <[email protected]>

+

+	[truetype] Do linear scaling for FT_LOAD_NO_HINTING (#50470).

+

+	* src/truetype/ttobjs.h (TT_SizeRec): Add field `hinted_metrics' to

+	hold hinted metrics.

+	Make `metrics' a pointer so that `tt_glyph_load' can easily switch

+	between metrics.

+

+	* src/truetype/ttdriver.c (tt_size_request): Updated.

+	(tt_glyph_load): Use top-level metrics if FT_LOAD_NO_HINTING is

+	used.

+

+	* src/truetype/ttgload.c (TT_Hint_Glyph, TT_Process_Simple_Glyph,

+	TT_Process_Composite_Component, load_truetype_glyph,

+

+	* src/truetype/ttsubpix.c (sph_set_tweaks): Updated.

+

+2017-04-22  Werner Lemberg  <[email protected]>

+

+	Add new `slight' auto-hinting mode.

+

+	This mode uses fractional advance widths and doesn't scale glyphs

+	horizontally, only applying vertical scaling and hinting.

+

+	At the same time, the behaviour of the `light' auto-hinter gets

+	restored for backward compatibility: Both vertical and horizontal

+	scaling is again based on rounded metrics values (this was changed

+	in a commit from 2017-03-30 as a side effect).  To be more precise,

+	the behaviour is restored for TrueType fonts only; for other font

+	formats like Type 1, this is a new feature of the `light' hinting

+	mode.

+

+	* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.

+	(FT_RENDER_MODE_SLIGHT): New render mode.

+

+	* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add

+	`autohint_mode' and `autohint_metrics' fields.

+	* src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c

+	(af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init):

+	Updated.

+

+	* src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use

+	`autohint_metrics'.

+	(af_loader_load_glyph): s/internal/slot_internal/.

+	Initialize `autohint_metrics' and `autohint_mode' depending on

+	current auto-hint mode.

+	Use `autohint_metrics'.

+	Updated.

+

+	* src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated.

+

+	* src/base/ftobjs.c (FT_Load_Glyph): Updated.

+	(FT_New_Size): Allocate `internal' object.

+

+2017-04-22  Werner Lemberg  <[email protected]>

+

+	Introduce `FT_Size_InternalRec' structure.

+

+	We are going to extend this later on.

+

+	* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): New

+	structure with a single field `module_data'.

+

+	* src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of

+	`FT_Size' structure.

+

+	* src/cff/cffgload.c (cff_builder_init, cff_decoder_prepare): Use

+	* src/cff/cffobjs.c (cff_size_done): Deallocate `module_data'.

+	(cff_size_init, cff_size_select, cff_size_request): Use

+

+	* src/cif/cidobjs.c (cid_size_done, cid_size_init,

+	cid_size_request): Use `size->internal->module_data' instead of

+	* src/psaux/psobjs.c (t1_builder_ini): Use

+	`size->internal->module_data' instead of `size->internal'.

+

+	* src/type1/t1objs.c (T1_Size_Done, T1_Size_Init, T1_Size_Request):

+	Use `size->internal->module_data' instead of `size->internal'.

+

+

+	[autofit] Prevent overlapping blue zones.

+

+	Problem reported as

+

+	  https://github.com/google/fonts/issues/632

+

+	The font in question (Nunito) has values 705 and 713 for the

+	reference and overshoot values, respectively, of the first blue

+	zone.  Blue zone 2, however, has value 710 for both the reference

+	and overshoot.  At 12ppem, reference and overshoot of blue zone 0

+	becomes 8px, while blue zone 2 becomes 9px.

+

+	A peculiarity of this font is that the tops of isolated vertical

+	stems like `N' have a slight overshoot also.  The auto-hinter tries

+	to find the nearest blue zone using the *original* coordinates.  For

+	vertical stems, this is value 713.  For normal horizontal tops like

+	in character `E', this is value 710.  Since value 713 is mapped to

+	8px but value 710 to 9px, `N' and similar characters are one pixel

+	higher than `E', which looks very bad.

+

+	This commit sanitizes blue zones to avoid such a behaviour.

+

+	* src/autofit/aflatin.c (af_latin_sort_blue): New function.

+

+	[truetype] Integer overflow issues.

+

+	Reported as

+

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7718

+

+	* src/truetype/ttinterp.c (Ins_MIRP): Use ADD_LONG.

+

+2018-04-15  Alexei Podtelezhnikov  <[email protected]>

+

+	[build] Use `info' function of make 3.81.

+

+	* configure, docs/INSTALL, docs/INSTALL.CROSS, docs/INSTALL.GNU,

+	docs/INSTALL.UNIX, docs/MAKEPP: Bump make version requirements.

+

+	* builds/detect.mk (std_setup): Replace `echo' with `info'.

+	(dos_setup): Removed.

+	* builds/unix/install.mk, builds/modules.mk, builds/dos/detect.mk,

+

+2018-04-10  Nikolaus Waxweiler  <[email protected]>

+

+	* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive

+	modernization measures.

+

+	This brings up the minimum required CMake version to 2.8.12.

+

+	The installation paths follow the GNU defaults now, e.g. installing on a

+	64 bit host will place binaries into the lib64/ folder on e.g. Fedora.

+

+	Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).

+

+	CMake will no longer look for a C++ compiler.

+

+	Library and .so version now match the Autotools build.

+

+	Comments in the build file and informational messages now use platform

+	agnostic example commands.

+

+	ftoption.h and ftconfig.h are written directly without a redundant `-new'

+	copy.

+

+	External dependencies are expressed as option()s and will turn up as such

+	in cmake-gui.

+

+	Internal: Properties such as dependencies and include directories are now

+	privately set on the freetype library instead of globally.

+

+	The CPack definitions have been cleaned up, the `make dist' has been

+	removed. Source packages generated with CPack don't contain Autotools

+	files and aren't used by the maintainers anyway.

+

+	On Windows, src/base/ftver.rc is compiled to decorate the library with

+	version and copyright information.

+

+	A pkg-config file is now generated and installed.

+

+	[truetype] Integer overflow issues.

+

+	Reported as

+

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7453

+

+	* src/truetype/ttinterp.c (Round_Super, Round_Super_45): Use

+	ADD_LONG and SUB_LONG.

+

+2018-04-06  Alexei Podtelezhnikov  <[email protected]>

+

+	[windows, wince] Clean up legacy project files.

+

+	* builds/wince/vc2005-ce/freetype.vcproj,

+	[cff, type1] Sanitize `BlueFuzz' and `BlueShift'.

+

+	Reported as

+

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7371

+

+	* src/cff/cffload.c (cff_load_private_dict): Sanitize

+	`priv->blue_shift' and `priv->blue_fuzz' to avoid overflows later

+	on.

+

+	* src/type1/t1load.c (T1_Open_Face): Ditto.

+

+2018-04-04  Ben Wagner  <[email protected]>

+

+	* src/truetype/ttobjs.c (trick_names): Add 3 tricky fonts (#53554),

+	`DFHei-Md-HK-BF', `DFKaiShu-Md-HK-BF' and `DFMing-Bd-HK-BF'.

+	(tt_check_trickyness_sfnt_ids): Add checksums for 3 tricky fonts

+	in above.

+

+2018-04-01  Werner Lemberg  <[email protected]>

+

+	* builds/toplevel.mk (work): Use $(SEP).

+

+	This fixes the `make refdoc' using Cygwin: $(CAT) is `type' on this

+	platform, and this program only understands backslashes in paths.

+

+	Reported by Nikhil Ramakrishnan <[email protected]>.

+

+2018-03-30  Werner Lemberg  <[email protected]>

+

+	[truetype] Fix memory leak (only if tracing is on).

+

+2018-03-10  Nikolaus Waxweiler  <[email protected]>

+

+	* CMakeLists.txt (BASE_SRCS): Update to changes from 2018-03-05.

+

+2018-03-09  Chun-wei Fan  <[email protected]>

+

+	* CMakeLists.txt [win32]: Allow MSVC DLL builds (#53287).

+

+	Do not limit DLL builds to MinGW, since we already have

+	`__declspec(dllexport)' directives in `ftconfig.h'.

+	Also suppress more warnings for POSIX functions.

+

+2018-03-08  Hugh McMaster  <[email protected]>

+

+	Make installation of `freetype-config' optional (#53093).

+

+	* builds/unix/configure.raw: Add option `--enable-freetype-config'

+	and set `INSTALL_FT2_CONFIG'.

+	* builds/unix/unix-def.in (INSTALL_FT2_CONFIG): Define.

+	* builds/unix/install.mk (install): Handle it.

+

+2018-03-05  Werner Lemberg  <[email protected]>

+

+	Make `ftlcdfil.c' part of the `base' module.

+

+	`ftobjs.c' needs `ft_lcd_padding'.

+

+	Problem reported by duhuanpeng <[email protected]>.

+

+	* modules.cfg (BASE_EXTENSIONS): Don't include `ftlcdfil.c'.

+

+	* src/base/ftbase.c: Include `ftlcdfil.c'.

+	* src/base/rules.mk (BASE_SRC): Add `ftlcdfil.c'.

+	* src/base/Jamfile (_sources): Adjusted.

+

+	* docs/INSTALL.ANY: Updated.

+

+2018-03-05  Werner Lemberg  <[email protected]>

+

+	Make `ftfntfmt.c' part of the `base' module.

+

+	`ftobjs.c' needs `FT_Get_Font_Format'.

+

+	Problem reported by duhuanpeng <[email protected]>.

+

+	* modules.cfg (BASE_EXTENSIONS): Don't include `ftfntfmt.c'.

+

+	* src/base/ftbase.c: Include `ftfntfmt.c'.

+	* src/base/rules.mk (BASE_SRC): Add `ftfntfmt.c'.

+

+	* docs/INSTALL.ANY: Updated.

+

+2018-03-01  Werner Lemberg  <[email protected]>

+

+2018-02-23  Werner Lemberg  <[email protected]>

+2018-02-06  Werner Lemberg  <[email protected]>

+

+	[truetype] Integer overflow issues.

+

+

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=6027

+	SUB_LONG; avoid FT_ABS.

+

+2018-02-04  Alexei Podtelezhnikov  <[email protected]>

+

+	[unix] Use -fvisibility=hidden.

+

+	It is now widely recommended that ELF shared libraries hide symbols

+	except those with explicit __attribute__((visibility("default"))).

+	This is supported by all major compilers and should rather be an

+	option in libtool.

+

+	* builds/unix/configure.raw: Add -fvisibility=hidden to CFLAGS.

+	* builds/unix/ftconfig.in, builds/vms/ftconfig.h,

+	include/freetype/config/ftconfig.h (FT_EXPORT): Use visibility

+

+	* builds/unix/install.mk (clean_project_unix, distclean_project_unix):

+	Use libtool.

+	* builds/freetype.mk: Minor.

+

+2018-01-07  Ewald Hew  <[email protected]>

+

+	[psaux] Fix Type 1 glyphs with too many stem hints.

+

+	According to the CFF specification, charstrings can have up to 96 stem

+	hints. Due to hint replacement routines in Type 1 charstrings, some

+	glyphs are rejected by the Adobe engine, which implements the above

+	limit. This fix turns off hinting for such glyphs.

+

+	* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling

+	`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off

+	hinting.

+

+2018-01-06  Werner Lemberg  <[email protected]>

+

+	Add `FT_Done_MM_Var'.

+

+	This is necessary in case the application's memory routines differ

+	from FreeType.  A typical example is a Python application on Windows

+

+	[cff] Fix family name logic of pure CFF fontdata (#52056).

+

+	1. If `FamilyName' is present in the CFF font, use this for

+	   FT_Face's `family_name'.

+	2. Otherwise, use the face name and chop off any subset prefix.

+	3. If at this point FT_Face's `family_name' is set, use this

+	   together with the full name to determine the style.

+	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.

+	5. If we don't have a valid style, use "Regular".

+

+	Previously, FT_Face's `family_name' entry for pure CFF fontdata

+	nearly always was the fontname itself, instead of the `FamilyName'

+	entry in the CFF font (assuming there is one).

+

+	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

+

+2017-09-18  Alexei Podtelezhnikov  <[email protected]>
