-
- [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/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'.
- (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
-
- http://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]>

-
- [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 backwards 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
- subpixel hinting mode.
-
-2013-02-05 Werner Lemberg <[email protected]>
-
- [truetype] A better fix for Savannah bug #38211.
-
- * src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to
- MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock).
-
-2013-02-01 Alexei Podtelezhnikov <[email protected]>
-
- [pcf] Streamline parsing of PCF encoding table.
-
- * src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop.
- Reallocate array instead of using temporary storage.
-
-2013-02-01 Werner Lemberg <[email protected]>
-
- Fix Savannah bug #38227.
-
- * builds/unix/freetype-config.in: Set LC_ALL.
-
-2013-02-01 Werner Lemberg <[email protected]>
-
- Fix Savannah bug #38221.
-
- This complements commit 83c0ebab.
-
- * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with
- `TT_USE_BYTECODE_INTERPRETER'.
-
-2013-02-01 Werner Lemberg <[email protected]>
-
- [truetype] Fix Savannah bug #38211.
-
- * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical
- to other interpreters if rp1 == rp2 (which is invalid).
-
-2013-01-28 Alexei Podtelezhnikov <[email protected]>
-
- [base] Small optimization of BBox calculation.
-
- * src/base/ftbbox.c (BBox_Cubic_Check): Use FT_MSB function in
- scaling algorithm.
-

- [sfnt] Fix broken pointer overflow checks.

-
- [truetype] Improve sub-pixel 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.

- [truetype] Improve accuracy of normalization of short vectors.
-
- Unit vector components are stored as 2.14 fixed-point numbers. In

- [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.

- [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

- Fix `checking if gcc static flag -static works' test.
-
- On my linux build tree, I receive yes answer in in every package I
- build except freetype for this test checking if gcc static flag
- `-static' works
-
- On 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
- LDFLAGS and this broke static flag test.
-
- * builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after
- LT_INIT has run.

-
- [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
-
- http://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_DRC_SRC): Updated.

-
- [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.

-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.

- 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

- [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

-
-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
-
- http://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.
-
- * 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
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (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:
-
- 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'.

-
- * 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 (comparision 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.

-
- [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

-
- 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

-
- Replace "%lx" for memory address by "%p", LLP64 platforms.
-
- On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover

- [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:
- http://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.
-

-
- [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.

-
- [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]>

-
- * src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid)
- `lineto' immediately after `hsbw', in accordance with Acrobat, GS,
- and others.
-
-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]>

-
- [raster] Fix Savannah bug #29335.
-
- * src/raster/ftraster.c (Line_Up): Use slow multiplication to
- prevent overflow. This shouldn't have any serious impact on speed,
- however.
-
-2010-04-05 Werner Lemberg <[email protected]>
-
- Add new function `FT_Library_SetLcdFilterWeights'.
-
- This is based on code written by Lifter

+ [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

+
+ [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.

+ 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_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
+
+ http://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,

+ * docs/LICENSE.TXT: Updated.
+
+2013-04-12 Werner Lemberg <[email protected]>

+
+ 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]>

+
+2013-03-14 Werner Lemberg <[email protected]>
+

+ */*: Use `FT_THROW'.
+
+ This is essentially a mechanical conversion, adding inclusion of

+
+ To convert the remaining occurrences of FT_Err_XXX and friends it is

+
+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.

+
+ [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.

+ assignment of F_dot_P to its theoretical maximum in case we decide
+ to scale back its type later.

+
+ [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
+
+ http://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.

+
+ [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.

+ 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.

+ [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

+ 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).

+
+ 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
+
+ http://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.

+
+ [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.
