89a529f3	2013-08-02T14:50:23	[autofit] Fix `make multi'. * include/freetype/config/ftconfig.h (FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF): New macros. * src/autofit/afglobal.c (af_writing_system_classes, af_script_classes): Use FT_LOCAL_ARRAY_DEF. * src/autofit/afglobal.h: Declare `af_writing_system_classes' and `af_script_classes'. * src/autofit/afloader.c: Include `afpic.h'.
72f5ff5b	2013-07-31T22:49:29	[autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts. For example, the `latin' writing system (in file `aflatin.c') is able to support scripts like Latin, Cyrillic, Armenian, etc., which can be handled similarly. Scripts are now named using four-letter OpenType tags. * src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure. It holds pointers to functions which can be shared among related scripts. (AF_WritingSystem): New enumeration. (AF_Script): Revised values using four-letter tags.

5d6a3605	2013-07-30T23:17:04	[autofit] Variable renaming. * src/autofit/aftypes.h (AF_ScriptMetricsRec): s/clazz/script_class/. Update all users.
e3c93015	2013-03-14T11:21:17	/: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335	2013-03-14T10:27:35	/: 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.
dda1e93d	2012-10-20T08:34:57	[autofit] Fix `make multi CC=c++'. * src/autofit/aflatin.c, src/autofit/aflatin2.c: Include `afglobal.h'. * src/autofit/afloader.c: Fix order of header files. * src/autofit/afmodule.c: Include `afglobal.h' and `aferrors.h'.

10364096	2012-03-11T15:20:32	[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.
5621fdd4	2012-02-29T13:33:33	[autofit] Don't synchronize digit widths for light rendering mode. We don't hint horizontally in this mode. * src/autofit/afloader.c (af_loader_load_g) <Hint_Metrics>: Implement it.
63486789	2012-02-17T14:55:27	[autofit] Fix outline flags. * src/autofit/afloader.c (af_loader_load_g): Don't reassign `outline.flags' so that this information is preserved. See discussion starting at http://lists.gnu.org/archive/html/freetype-devel/2012-02/msg00046.html
e343e87d	2012-02-07T09:40:11	[autofit] Harmonize function arguments. * src/autofit/afloader.c, src/autofit/afloader.h: Use `FT_Int32' for `load_flags'.
d503b1bc	2011-04-18T19:05:28	Integrate autofitter debugging stuff. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_DEBUG_AUTOFIT): New macro. * include/freetype/internal/fttrace.h: Add trace components for autofitter. * src/autofit/aftypes.h (AF_LOG): Removed. (_af_debug): Removed. * src/autofit/*: s/AF_DEBUG/FT_DEBUG_AUTOFIT/. s/AF_LOG/FT_TRACE5/. Define FT_COMPONENT where necessary.

6cfbb23c	2011-02-26T17:32:38	[autofit] Some comments. Whitespace.
8b84c9d1	2009-04-27T19:40:35	autohinter: Don't change digit widths if all widths are the same. This fixes FreeDesktop bug #21197. * src/autofit/afglobal.c (AF_DIGIT): New macro.

dbf3b43a	2006-12-07T21:18:09	* src/autofit/afloader.c (af_loader_load_g): small adjustment to the spacing of auto-fitter glyphs. This only impacts rare cases (e.g. Arial Bold at rather small character sizes)
40604748	2006-11-02T16:37:35	- fixed a bug in af_compute_direction which generated ugly glyphs - added more debug/log messages to help improve the auto-fitter
65c7c773	2006-04-13T07:51:58	* src/autofit/afloader.c: removing superfluous code in the auto-fitter's loader
2ce92037	2006-03-23T20:58:20	- added FT_Get_SubGlyph_Info API to freetype.h - small fix to lsb/rsb delta computations - cleaning up Jamfile
dad2a2de	2006-03-20T11:48:13	* src/cache/ftccache.h, src/cache/ftcglyph.h, src/cache/ftcimage.h, src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h, src/cache/ftcmru.h: copying the cache's internal header files which were located in 'include/freetype/cache' to the 'src/cache' directory instead. Note that these files are not used by FreeType clients, all cache public APIs have been already moved to include/freetype/ftcache.h, and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it. the move is to allow us to modify the internals without intereference from rogue clients. Note that there are no known client that accesses the cache internals at the moment.
2e48a1a1	2006-02-27T09:18:07	* src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics, FT_Load_Glyph): Re-enable glyph metrics grid-fitting. It is now done in the base layer. (FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and height are not too small or too large, just like we were doing in 2.1.10. * src/autofit/afloader.c (af_loader_load_g): The vertical metrics are not scaled.
4cdb45c0	2006-02-09T14:17:04	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.

It is disabled by default, you need to #define AF_USE_WARPER in aftypes.h to enable it.
9fbd2ab8	2005-10-28T16:14:14	- various performance enhancements - fixing apinames.c, adding support for Watcom and Borland compilers - adding generation of exported symbols list to the build system, including the Unix one !! sorry Werner, I have no time to document this in ChangeLog at the moment
a37745ba	2005-03-23T16:45:24	* docs/CHANGES, docs/INSTALL.ANY: Updated. * include/freetype/ftmoderr.h: Replace `Autohint' with `Autofit'.

e664efad	2004-06-04T17:41:59	* 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
10bf05a3	2004-04-21T14:30:37	* src/cff/cffobjs.c (cff_face_init): fixed a small memory leak * src/autofit/afloader.c, src/autofit/afmodule.c, src/base/ftdebug.c: removed compiler warnings * src/autofit/aftypes.h, src/lzw/zopen.c, src/pcf/pcfdrivr.c, src/pcf/pcfread.c, src/psaux/psobjs.c, src/type42/t42drivr.c: changed data arrays to "const" to avoid populating the ".data" segment
8bb07e63	2004-03-27T08:43:17	Add vertical phantom points. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add `top_bearing', `vadvance', `pp3, and `pp4'. * src/autofit/afloader.c (af_loader_load_g): Handle two more points. * src/autohint/ahhint.c (ah_hinter_load): Handle two more points. * src/truetype/ttgload.c (Get_VMetrics): New function. (TT_Load_Simple_Glyph, TT_Process_Simple_Glyph): Handle two more points. (load_truetype_glyph): Use Get_VMetrics. Handle two more points. (compute_glyph_metrics): Thanks to vertical phantom points we now can always compute `advance_height' and `top_bearing'. * src/truetype/ttobjs.h (TT_SubglyphRec): Add vertical phantom points. * src/autohint/ahglyph.c (ah_outline_load): Fix allocation of `news'. Converting some files to Unix end-of-line convention.
9bfbf79c	2004-02-23T21:08:37	adding support for dummy script, i.e. no-hinting for non latin glyphs
1029ed26	2004-02-23T20:40:30	* src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c, src/autofit/afloader.c, src/types.h: grave bugs were fixed. The auto-fitter works, doesn't crashes, but still produces unexpected results !!
6b3d00e1	2004-02-03T21:34:29	* src/type1/t1load.c (parse_dict): Handle `RD' and `-\|' commands outside of /Subrs or /CharStrings. This can happen if there is additional code manipulating those two arrays so that FreeType doesn't recognize them properly. (T1_Open_Face): Improve an error message. Remove CR/LF on many files.
f546bacd	2004-02-01T16:59:06	* src/sfnt/Jamfile: removing "ttcmap" from the list of sources * src/cache/, include/freetype/cache/: fixing a bug after heavy testing. The current sources are now "release candidates" for the final version of the cache sub-system * Jamfile: updating "refdoc" target, and adding "autohint" to the list of modules to build. Both the autohinter and autofitter will be built by default. But which one will be used is determined by the content of "ftmodule.h" * src/autofit/*: much updates, but the code is still buggy as hell. Aargh..

[autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts.

Scripts are now named using four-letter OpenType tags. * src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure.

*/*: 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.

[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.
