2019-02-23  Werner Lemberg  <[email protected]>

	* src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets.

	The function only provided a framework without an actual
	implementation, which this commit removes.

2019-02-23  Werner Lemberg  <[email protected]>

	* src/tools/update-copyright-year: Insert `(C)'.

2019-02-21  Armin Hasitzka  <[email protected]>

	[truetype] Mask numeric overflows.

	* src/truetype/ttinterp.c (Move_CVT, Move_CVT_Stretched, Ins_MIRP):
	Mask numeric overflows.

	Reported as

	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11681
	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11734

2019-02-21  Armin Hasitzka  <[email protected]>

	[psaux] Mask numeric overflow.

	* src/psaux/cffdecode.c (cff_decoder_parse_charstrings): Mask numeric
	overflow.

	Reported as

	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=13041

2019-02-16  Wink Saville  <[email protected]>

	* src/autofit/afwarp.h (af_warper_compute): Fix declaration.

2019-02-02  Nikolaus Waxweiler  <[email protected]>

	[truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics.

	Instead of setting typo or win metrics as the new `FT_Face' metrics
	indiscriminately, apply only typo deltas to the currently active
	`FT_Face' metrics.  This prevents line height differences when the
	default outlines were used as the regular face and instances for
	everything else, for example.

	* src/truetype/ttgxvar.c (tt_apply_mvar): Implement.

2019-02-02  Nikolaus Waxweiler  <[email protected]>

	[sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set.

	If the `OS/2' table exists and `fsSelection' bit 7
	(USE_TYPO_METRICS) is set, use the `sTypo*' set of values to compute
	the `FT_Face's ascender, descender, and height.  Otherwise, fall
	back to old behavior.

	* src/sfnt/sfobjs.c (sfnt_load_face): Implement.

2019-01-18  John Tytgat  <[email protected]>

	[sfnt] Handle TT fonts having two PostScript font names (#55471).

	* src/sfnt/sfdriver.c (sfnt_get_name_id): Prefer English over any
	other language found for PostScript font names.

2019-01-08  Chris Liddell <[email protected]>

	[psaux] Fix closepath (#55414).

	All of the Type 1 path building is done with code common to the
	revised CFF engine, with the exception of closepath, which was still
	calling ps_builder_close_contour(), thus previously cached segments
	were not always written to the path, and glyph corruption, or even
	invalid outlines were possible.

	* src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>:
	Switch to calling `cf2_glyphpath_closeOpenPath'.

2018-12-29  Werner Lemberg  <[email protected]>

	* src/autofit/aflatin2.c: Some fixes from `aflatin.c' (#55310).

2018-12-25  Werner Lemberg  <[email protected]>

	[gxvalid] Fix compiler warnings.

	* src/gxvalid/gxvjust.c (gxv_just_check_max_gid),
	src/gxvalid/gxvmort.c (gxv_mort_coverage_validate): Use `FT_UNUSED'.

2018-12-11  Werner Lemberg  <[email protected]>

	* src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test.

	`control_len' only gets its value from `n_ins' (and vice versa),
	which is always read as `unsigned short' and thus can't be larger
	than 0xFFFF.

2018-12-04  Werner Lemberg  <[email protected]>

	[bdf] Ignore data after `ENDFONT'.

	Reported as

	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10798

	cff_get_mm_weightvector): New functions.
	(cff_service_multi_masters): Register them.

	* src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated.
	This driver doesn't use the new interface.

	* src/type1/t1load.c (T1_Set_MM_WeightVector,
	T1_Get_MM_WeightVector): New functions.
	* src/type1/t1driver.c (t1_service_multi_masters): Register them.

	[builds] Belated DLL support with vc2002-vc2008.

	The solution and project files should be automatically upgraded for
	the approriate Visual C++ version.

	* builds/windows/visualc/freetype.{sln,vcproj}: Major upgrades.
	* builds/windows/visualc/index.html: Document the change.
	* builds/windows/vc2005, builds/windows/vc2008: Removed as redundant.

2018-11-22  Armin Hasitzka  <[email protected]>

2018-09-27  Alexei Podtelezhnikov  <[email protected]>

	Align FreeType with standard C memory management.

	* include/freetype/ftsystem.h: Include FT_TYPES_H.
	(*FT_Alloc_Func, *FT_Realloc_Func): Use size_t for the size arguments.
	* src/raster/ftmisc.h: Ditto.

	FT_Offset, aka size_t, for the size arguments.

2018-09-25  Werner Lemberg  <[email protected]>

	Fix handling of `FT_Bool'.

	Before this commit we had code like

	  (FT_Bool)( globals->glyph_styles[gindex] & 0x8000)

	Since `FT_Bool' is defined to be an `unsigned char', the code
	evaluated to something like

	  (unsigned char)( 0x8532 & 0x8000)

	which in turn expanded to

	  (unsigned char)( 0x8000)

	and finally yielded 0x00 – i.e., false – not as expected.

	Problem reported and analyzed by Tony Smith <[email protected]>.

	* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
	zero so that we always have a Boolean expression.

	*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
	possible.

2018-09-23  Alexei Podtelezhnikov  <[email protected]>

	[bdf] Speed up charmap access.

	This makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster.

	* src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Help binary search
	with continuous prediction.

2018-09-22  Alexei Podtelezhnikov  <[email protected]>

	* src/base/ftobjs.c (ft_glyphslot_preset_bimap): Another tweak.

	This one should be clearer. When the rounded monochrome bbox collapses
	we add a pixel that covers most if not all original cbox.

2018-09-21  Alexei Podtelezhnikov  <[email protected]>

	* src/base/ftobjs.c (ft_glyphslot_preset_bimap): Further tweak.

2018-09-21  Ben Wagner  <[email protected]>

	Improve auto-hinter handling of bitmap fonts (#54681).

	For bitmap fonts, `FT_Load_Glyph' should either return an error or
	not set the format to `FT_GLYPH_FORMAT_OUTLINE'.  However, in this
	case `FT_Load_Glyph' calls into the auto-hinter which calls back
	into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
	marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
	(even though it doesn't have any path).  It appears that the
	auto-hinter should not be called when the face doesn't have
	outlines.  The current test for using the auto-hinter in
	`FT_Load_Glyph' checks whether the driver supports scalable
	outlines, but not if the face supports scalable outlines.

	* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
	scalable outlines.

2018-09-21  Werner Lemberg  <[email protected]>

	[raster] Fix disappearing vertical lines (#54589).

	* src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case
	where both left and right outline exactly pass pixel centers.

2018-09-20  Alexei Podtelezhnikov  <[email protected]>

	* src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak.

	This adds pixels in case a contour goes through the center
	and they need to be turned on in the b/w rasterizer.

2018-09-20  Alexei Podtelezhnikov  <[email protected]>

	[pcf] Replace charmap implementation.

	PCF comes with charmap lookup table, aka PCF encodings.  Using it
	directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times
	faster than the original BDF-like binary searches.

	* src/pcf/pcf.h (PCF_EncodingRec): Removed.
	(PCF_FaceRec): Remove `nencodings' and `encodings'.
	* src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Replaced.
	* src/pcf/pcfread.c (pcf_get_encodings): Store data differently.

2018-09-20  Werner Lemberg  <[email protected]>

	(FT_GlyphLoader_CopyPoints): Do it.

2018-09-19  Alexei Podtelezhnikov  <[email protected]>

	[pcf] Prepare to replace charmap implementation.

	* src/pcf/pcf.h (PCF_FaceRec): Updated to include...
	(PCF_EncRec): ... this new structure to store charmap geometry.

	* src/pcf/pcfread.c (pcf_get_encodings): Store charmap geometry.

2018-09-18  Alexei Podtelezhnikov  <[email protected]>

	Remove unused fields.

	* src/pcf.h (PCF_FaceRec): Remove `charmap' and `charmap_handle'.
	* src/bdfdrvr.h (BDF_FaceRec): Ditto.
	* src/winfonts/winfnt.h (FNT_FaceRec): Ditto.

	* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.
	(get_win_string, get_apple_string): Return NULL when the PostScript
	font name characters is not according to specification.
	(get_win_string): Make trace output work if the high byte if
	non-zero.
	(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
	Win PS name (when there is also an Apple PS name); change this into
	a fallback to Apple PS name in case the Win PS name is invalid.

	[truetype] Avoid nested frames.

	Triggered by

	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054

	* src/truetype/ttgload.c (load_truetype_glyph): Don't use variable
	`opened_frame' to trace whether a frame must be closed at the end of
	function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which
	gets called for space glyphs) uses a frame by itself.  Instead,
	close the frame after loading the header, then use another frame for
	the remaining part of the glyph later on.

	Also avoid calling `tt_get_metrics' twice under some circumstances.

	[sfnt] Preliminary support of coloured layer outlines (#44689).

	This commit enables OpenType's COLR/CPAL table handling; a typical
	application are color emojis that can be scaled to any size.

	If the color palette does not exist or is invalid, the rendering
	step rasterizes the outline instead.  The current implementation
	assumes that the foreground is black.

	Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

	There are still some issues with metrics; additionally, an API to
	fetch color layers is missing.

	* devel/ftoption.h, include/freetype/config/ftoption.h

	Fix DLL compilation on Solaris.

	AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'.  The
	Solaris Studio 12.1 through 12.5 compilers see the
	`-fvisibility=hidden' flag, but ignore it with a warning of:

	  cc: Warning: Option -fvisibility=hidden passed to ld,
	               if ld is invoked, ignored otherwise

	AC_LINK_IFELSE does the compile and then tries to link the result,
	at which point the Solaris linker will issue an error:

	  ld: fatal: option '-fvisibility=hidden' is incompatible with
	      building a dynamic executable

	If we don't use AC_LINK_IFELSE to catch the error, then configure
	will fail further tests which attempt to link, such as those testing
	dependencies like `libbz2'.

	Also, don't try adding `-fvisibility' if we have already added
	`-xldscope', just use one of them, since Sun Studio 12 and earlier
	compilers only issue a warning, and don't try passing through to the
	linker to generate an error, so AC_LINK_IFELSE doesn't catch them.

	Tested on Solaris 11.4 beta with compiler versions:

	  Sun Studio 8 (Sun C 5.5)
	  Sun Studio 10 (Sun C 5.7)
	  Sun Studio 11 (Sun C 5.8)
	  Sun Studio 12 (Sun C 5.9)
	  Sun Studio 12.1 (Sun C 5.10)
	  Oracle Solaris Studio 12.2 (Sun C 5.11)
	  Oracle Solaris Studio 12.3 (Sun C 5.12)
	  Oracle Solaris Studio 12.4 (Sun C 5.13)
	  Oracle Developer Studio 12.5 (Sun C 5.14)
	  Oracle Developer Studio 12.6 (Sun C 5.15)
	  gcc 5.5.0
	  gcc 7.3.0

	and verified the libfreetype.so.6 generated by each of those
	compilers exported the same set of symbols.

	* 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.

	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
	   CFF       Adobe  Adobe

	The interpreter in Type 1 mode rewinds the charstring after collecting

	some charstrings use `endchar' in a final subroutine call, rewinding to

	We used to split large glyphs into horizontal bands and continue

	Bitmap metrics presetting [1/2].

	This mainly just extracts the code for presetting the bitmap metrics
	from the monochrome, grayscale, and LCD renderers into a separate
	function.

	* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that
	calculates prospective bitmap metrics for the given rendering mode.
	* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
	Declare it.

	* src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds

	notice for `SubFont' in Type 1 mode.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Move `psdecode' into `psobjs'.

	As the former only contains a single procedure, move it into
	`psobjs' for simplicity.  Also change the parameter order to the
	conventional one.

	* src/psaux/psdecode.c (ps_decoder_init): Moved to...
	* src/psaux/psobjs.c: ...Here.

2017-09-25  Ewald Hew  <[email protected]>

	[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
	first, before proceeding to build the glyph outline.

	* src/psaux/psintrp.c (cf2_interpT2CharString): New
	`initial_map_ready' boolean flag.
	Ignore outline commands and hint changes on first pass.

	left-sidebearing.

2017-09-25  Ewald Hew  <[email protected]>

	[cid] Use the new engine.

	* src/cid/cidgload.c: Update includes.

	[psaux] Change subfont synthesis for CID fonts.

	Change `t1_make_subfont' to take in the Private dict record as an
	argument.  This is because Type 1 and CID font records in FreeType
	have this in different places.

	* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to
	`FT_Face' so that CID is also accepted.
	Take `PS_Private' as an argument and let caller figure out where the
	Private dict actually is.
	Update references.

	* include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update

	<cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1,
	2).
	<cf2_cmdRMOVETO>: Do not actually move the `glyphPath' while doing
	flex.  This is to avoid closing the current contour.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Extend Adobe interpreter (callothersubr).

	* src/psaux/psintrp.c (cf2_interpT2CharString)
	<cf2_escCALLOTHERSUBR>: Copy code from
	`t1_decoder_parse_charstrings' (in `t1decode.c').
	OtherSubr 3 (change hints) should reset the hintmask, so that the
	new hints are applied.
	Fix function calls and stack access.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Extend Adobe interpreter (pop).

	* src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Extend Adobe interpreter (div, four-byte numbers).

	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add
	Type 1 mode.  Type 1 requires large integers to be followed by
	`div'; cf. `Adobe Type 1 Font Format', section 6.2.
	<op == 255>: Push Type 1 four-byte numbers as `Int' always.  This is
	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,
	cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode.

	<cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands
	for three normal stem hints.  This requires some recalculation of
	stem positions.
	Correction for left sidebearing.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Extend Adobe interpreter (hsbw, sbw).

	[psaux] Extend Adobe interpreter (closepath).

	* src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>:
	Use the right builder function.  We can use the `haveWidth' boolean
	already present, instead of implementing `parse_state'.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Add Type 1 operations to Adobe CFF interpreter.

	The following Type 1 specific ops have been added (copied from
	`t1decode'):

	  closepath
	  vstem3
	  hstem3
	  seac
	  sbw
	  callothersubr
	  pop
	  setcurrentpoint
	  hsbw

	The following require a Type 1 mode, because of differences in
	specification:

	  hstem
	  vstem
	  vmoveto
	  callsubr
	  div
	  rmoveto
	  hmoveto
	  Numbers

	The subsequent commits will implement these changes and adapt
	accesses of data and objects to the new interpreter.

	NOTE: Will not compile in the meantime!

	* src/psaux/psintrp.c: Add opcodes to enum.
	(cf2_interpT2CharString): Copy relevant code over from
	`t1_decoder_parse_charstrings' (in `t1decode.c').

2017-09-25  Ewald Hew  <[email protected]>

	[type1] Fixes for rendering.

	The Type 1 advance width calculation passes null for glyph slot,
	etc, which can cause null pointer access in the new interpreter.
	Fall back to the old one for now.

	Fix the large glyph retry code and ensure hinting and scaling flags
	are set properly.

	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a
	check for metrics_only.
	Set the `force_scaling' flag.
	(T1_Parse_Glyph): Updated.
	(T1_Load_Glyph): Add `hinting' and `scaled' flags.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Add missing objects (2/2).

	Synthesize a `SubFont' object for Type 1 fonts.  This is used in the
	interpreter to access Private dict data, which are stored in
	different places for Type 1 and CFF.  This allows the same data to
	be used in either mode.

	* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy
	required values to a dummy `CFF_SubFont' object.  This is similar to
	`cff_make_private_dict'.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux] Add missing objects for Type 1 (1/2).

	Move `CF2_Font' instance to `PS_Decoder'.  This is the context for
	the interpreter and since it is currently stored in `CFF_Font', is
	unavailable in Type 1 mode.

	* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New
	`cf2_instance' field.

	* src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to

	move to...
	* include/freetype/internal/psaux.h (PS_Driver): ...here.

2017-09-25  Ewald Hew  <[email protected]>

	[psaux, type1] Reorganize object fields.

	Make some fields more generic, so that we can access them the same
	way regardless of Type 1 or CFF.

	* include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face'
	to `FT_Face'.
	Remove unused fields.

	* src/psaux/psft.c: Update all accesses of `PS_Builder.face'.
	Add some asserts to guard against casting `T1_Face' as `TT_Face'.

	* src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow
	`CFF_GlyphSlot', so that we can pretend they are the same in the
	interpreter.

	* src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point):
	Updated with above changes.

2017-09-25  Ewald Hew  <[email protected]>

	offset has to be taken from the parent structure; in this case the
	`PairSet' table.

	* src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'.
	(otv_PairPos_validate): Adjust.

	[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]>
