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.

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 23df31ad 2007-01-13T08:45:00 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix compilation with C++ compiler. * src/autofit/afhints.c (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto. * src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in `modules.cfg'). * src/sfnt/ttsbit0.h: Remove. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.
Werner Lemberg 960ba59a 2006-12-01T08:20:47 * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are encoded in UTF-16BE. Patch from Rajeev Pahuja <rpahuja@esri.com>.

Formatting.
David Turner 80658e50 2006-11-28T08:09:20 * src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch * src/smooth/ftgrays.c: remove hard-coded error values, use FreeType ones instead * src/autofit/afhints.c (af_glyph_hints_dump_segments): remove unused variable
David Turner 1bd6c472 2006-11-25T01:30:40 * src/autofit/afhints.c: add stubs to link the "ftgrid" test program when debugging is disabled in the auto-hinter
David Turner 81e725f5 2006-11-23T14:49:48 * src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c, src/autofit/aftypes.h: Misc. auto-hinter improvements
Werner Lemberg 111b5aef 2006-11-03T09:40:12 * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'. Formatting
David Turner effd15de 2006-11-02T17:21:02 - merging af_corner_XXX and psh_corner_XXX functions into ft_corner_XXX versions in ftcalc.c - more auto-fitter debugging support
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
Werner Lemberg 545c4e56 2006-05-17T22:55:04 * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. Formatting, documentation fixes.
David Turner 281679de 2006-05-17T13:34:21 * include/freetype/internal/tttypes.h, src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c, src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c, src/type1/t1gload.c: this is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glypn vector themselves and the auto-fitter. note that we've started using inline assembler with GCC to implement FT_MulFix, given that this function is so damn important for the engine's performance. the resulting speed-up is about 25%.
Werner Lemberg 1be9ebf5 2006-01-22T06:58:16 * src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c. Formatting, copyright notices, copyright years.
David Turner bb4edc92 2006-01-21T14:31:45 * src/autofit/aflatin.c, src/autofit/afwarp.h, src/autofit/afwarp.c, src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c: adding experimental implementation of "warp hinting" (new hinting algorithm for gray-level and LCD rendering). It is disabled by default, you need to #define AF_USE_WARPER in aftypes.h to enable it.
David Turner 5b5f382b 2005-12-14T16:37:15 * src/autofit/aflatin.c, src/autofit/afhints.c: changed the implementation of the LIGHT hinting mode to completely disable horizontal hinting. This is an experimental effort to integrate David Chester's latest patch without fucking the other hinting modes as well. Note that this doesn't force auto-hinting for all fonts however.
Werner Lemberg cee37a3b 2005-11-12T07:34:40 Clean-up.
David Turner 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

Werner Lemberg a37745ba 2005-03-23T16:45:24 * docs/CHANGES, docs/INSTALL.ANY: Updated. * include/freetype/ftmoderr.h: Replace `Autohint' with `Autofit'. Add `OTvalid'. * src/autofit/aferrors.h: New file. * src/autofit/afglobal.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/afloader.c: s/FT_Err_/AF_Err_/. Include aferrors.h. * src/autofit/rules.mk (AUTOF_DRV_H): Include aferrors.h. * src/otvalid/otverror.h: s/FT_Mod_Err_OTV/FT_Mod_Err_OTvalid/.

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.
Werner Lemberg dfa46199 2004-03-05T09:26:24 * Jamfile, vms_make.com, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype/vcproj, include/freetype/ftmoderr.h: Add LZW module. * Jamfile.in: Removed. * docs/CHANGES: Updated. * include/freetype/internal/ftobjs.h: s/MIN/FT_MIN/, s/MAX/FT_MAX/, s/ABS/FT_ABS/. Updated all callers. * src/type1/t1load.c (parse_dict), src/pcf/pcfdrivr.c (PCF_Face_Init): Use FT_ERROR_BASE.

(PCF_Face_Init): Try LZW also. * src/gzip/ftgzip.c: s/0/Gzip_Err_Ok/ where appropriate. Beautify.
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..
David Turner 8ccb4552 2004-01-16T09:51:00 updates
David Turner cf2c49c8 2003-12-24T18:42:04 * fixed compilation problems in the cache sub-system * partial updates to src/autofit
