Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 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.

Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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
Werner Lemberg e343e87d 2012-02-07T09:40:11 [autofit] Harmonize function arguments. * src/autofit/afloader.c, src/autofit/afloader.h: Use `FT_Int32' for `load_flags'.
Werner Lemberg 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.

David Turner d91eebda 2007-01-26T15:05:41 improvement to glyph spacing, especially when light auto-hinting
David Turner 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)
David Turner 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
David Turner 65c7c773 2006-04-13T07:51:58 * src/autofit/afloader.c: removing superfluous code in the auto-fitter's loader
David Turner 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
David Turner 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.

(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.
Wu, Chia-I (吳佳一) 4cdb45c0 2006-02-09T14:17:04 Introduce experimental autofit CJK module based on akito's autohint patch.

It is disabled by default, you need to #define AF_USE_WARPER in aftypes.h to enable it.

David Turner 8530a228 2004-06-09T20:18:35 * include/freetype/freetype.h (FT_Glyph_Metrics, FT_GlyphSlotRec), src/autofit/afloader.c, src/autohint/ahhint.c: moved the definition of 'lsb_delta' and 'rsb_delta' from FT_GlyphMetrics to FT_GlyphSlotRec. The old location did BREAK BINARY COMPATIBILITY of the library !! * src/sfnt/sfobjs.c: removing compiler warning

David Turner 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
David Turner 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
Werner Lemberg 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.
David Turner 9bfbf79c 2004-02-23T21:08:37 adding support for dummy script, i.e. no-hinting for non latin glyphs
David Turner 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 !!
Werner Lemberg 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.
David Turner 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..
