Werner Lemberg 974b193b 2013-12-20T17:26:26 [autofit] Introduce `styles'. This is the new top-level structure for handling glyph input data; scripts are now defined separately. * src/autofit/aftypes.h (SCRIPT): Updated. (AF_ScriptClassRec): Move `blue_stringset' and `writing_system' members to ... (AF_Style_ClassRec): ... this new structure. (AF_Style): New enumeration. (AF_StyleMetricsRec): Replace `script' enumeration with `style_class' pointer. (AF_DEFINE_SCRIPT_CLASS, AF_DECLARE_SCRIPT_CLASS): Updated.

(STYLE): Redefine macro to load `afstyles.h'. (af_script_names) [FT_DEBUG_LEVEL_TRACE]: Replace with... (af_style_names): ... this array. (af_face_globals_compute_script_coverage): Renamed to...

Werner Lemberg cc25e3ae 2013-08-05T08:46:15 [autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary.

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

This one also fixes bug #12107 * src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without a 'kern' table.
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
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 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 !!
