Werner Lemberg 663486a7 2023-02-08T20:56:19 Fix `FT_LOCAL` and `FT_LOCAL_DEF` tags.
Werner Lemberg be724c81 2023-02-07T22:24:53 For debugging, avoid implicit conversion from integer to double. Otherwise we get zillions of clang 15 warnings. * src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/base/ftobjs.c, src/base/ftoutln.c, src/cff/cffparse.c, src/raster/ftraster.c, src/sfnt/pngshim.c, src/truetype/ttgload.c, src/truetype/ttgxvar.c, src/truetype/ttobjs.c, src/type1/t1gload.c: Use `double` cast in debugging and tracing macros.

Werner Lemberg 5aa2a5c3 2022-01-07T06:41:36 [autofit, pshinter] Use `FT_OFFSET`. This avoids ``` runtime error: applying zero offset to null pointer ``` warnings of clang's undefined behaviour sanitizer. * src/autofit/afcjk.c (af_cjk_hints_link_segments, af_cjk_hints_compute_edges, af_cjk_hints_compute_blue_edges, af_cjk_hint_edges, af_cjk_align_edge_points): Do it. * src/autofit/afhints.c (af_glyph_hints_align_edge_points, af_glyph_hints_align_strong_points): Ditto. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hints_link_segments, af_latin_hints_compute_edges, af_latin_hints_compute_blue_edges, af_latin_hint_edges): Ditto. * src/pshinter/pshalgo.c (psh_hint_table_init): Ditto.
Alexei Podtelezhnikov 68fae526 2021-09-30T22:59:04 * src/autofit/afhints.c (af_glyph_hints_reload): Decrease casting.
Werner Lemberg 825b7ea2 2021-07-12T22:11:24 [autofit] More clean-ups. * src/autofit/afhints.h (AF_GlyphHintsRec): Remove the no longer needed fields `xmin_delta` and `xmax_delta`. * src/autofit/afhints.c (af_glyph_hints_reload), src/autofit/afloader.c (af_loader_load_glyph): Updated.
David Turner a212668c 2021-06-02T19:07:56 Remove obsolete AF_Angle type and related sources. Move the af_sort_xxx() functions from afangles.c to afhints.c in order to get rid of the obsolete angle-related types, macros and function definitions.
David Turner 2f11522a 2021-06-02T19:05:09 Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose.

David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Werner Lemberg a9af6914 2018-09-25T09:10:09 Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
Werner Lemberg 0d4ca138 2018-08-31T06:53:52 * src/autofit/afhints.c (af_glyph_hints_reload): Add initialization.
Werner Lemberg c0ccf750 2018-08-30T09:56:09 [autofit] Trace `before' and `after' edges of strong points. * src/autofit/afhints.h (AF_PointRec) [FT_DEBUG_AUTOFIT]: New arrays `before' and `after'. * src/autofit/afhints.c (af_get_strong_edge_index): New auxiliary function. (af_glyph_hints_dump_points): Trace `before' and `after' edges. (af_glyph_hints_align_strong_points) [FT_DEBUG_AUTOFIT]: Set `before' and `after' information.
Werner Lemberg a0dd16fb 2018-08-15T18:13:17 Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. */* (FT_COMPONENT): Updated.
Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
Werner Lemberg 0a0c2256 2018-01-02T09:33:57 Update copyright year.
Werner Lemberg 8768536c 2017-10-12T00:13:51 [autofit] Better visualize table tracing in source code.
Werner Lemberg 0ab2b62d 2017-09-09T08:08:47 [autofit] Improve communication with ftgrid. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Provide values in font units.
Werner Lemberg 563ae780 2017-01-04T20:16:34 Update copyright year.
Werner Lemberg 4441f7b2 2016-12-26T17:08:17 Replace `foo == NULL' and `foo != NULL' with `!foo' and `foo', resp. Other minor formatting.
Werner Lemberg 1831e6f0 2016-07-15T10:35:32 [autofit] Update and improve segment and edge tracing. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace `delta' also. Don't show first point of segment as a replacement for `pos'; this is (a) misleading, since the difference to `pos' can be almost arbitrarily large in corner cases, and (b) it is better to have all segment data in font units instead of a single value given in output space coordinates. Improve layout. (af_glyph_hints_dump_edges): Show px->units and units->px conversion values for convenience. Improve layout.
Werner Lemberg 614a8f17 2016-03-21T19:39:14 * src/autofit/afhints.c (af_glyph_hints_reload): Thinko. This fixes the previous commit to this file.
Werner Lemberg 709486db 2016-03-20T22:20:32 [autofit] Show `near' points in tracing. * src/autofit/afhints.h (AF_FLAG_NEAR): New macro. * src/autofit/afhints.c (af_glyph_hints_dump_points): Implement it. (af_glyph_hints_reload): Handle AF_FLAG_NEAR.
Werner Lemberg baa41ff2 2016-01-30T07:44:30 [autofit] Minor tracing improvement. * src/autofit/afhints.c (af_glyph_hints_dump_points): Insert newline at the start of a new contour.

Werner Lemberg 2e09812c 2015-12-25T08:05:30 [autofit] Make top-to-bottom hinting work in latin auto-hinter. This improves rendering of scripts like Bengali or Devanagari. * src/autofit/afhints.c (af_axis_hints_new_edge): Add parameter to pass top-to-bottom hinting flag. This makes the function sort edges in descending vertical position. * src/autofit/afhints.c: Updated. * src/autofit/aflatin.c (af_latin_hints_compute_edges, af_latin_hint_edges): Use `top_to_bottom_hinting' flag. * src/autofit/afcjk.c (af_cjk_hints_compute_edges), src/autofit/aflatin2.c (af_latin2_hints_compute_edges): Updated.
Werner Lemberg 68fb4789 2015-11-15T13:06:48 * src/autofit/afhints.c (af_get_segment_index): Fix it. The old code was too simple, returning invalid values in most cases where a segment crosses the contour start.
Werner Lemberg 02cfd714 2015-10-29T20:50:57 * src/autofit/afhints.c (af_glyph_hints_dump_points): Minor.
Werner Lemberg 7f00fa64 2015-10-25T10:59:59 [autofit] Improve tracing. * src/autofit/afhints.c (af_print_idx, af_get_segment_index, af_get_edge_index): New functions. (af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'. Add segment and edge index for each point. Slightly change printing order of some elements. Don't print `-1' but `--' for missing elements. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove unnecessary `|', `[', and `]'. Don't print `-1' but `--' for missing elements.
Werner Lemberg a678560d 2015-05-28T17:31:15 Minor.
Alexei Podtelezhnikov 40914952 2015-04-29T21:57:30 [autofit] Speed up IUP. * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to the same position from true interpolation, use `scale' to reduce divisions.
Alexei Podtelezhnikov 67b912d2 2015-04-03T22:38:11 * src/autofit/afhints.c (af_glyph_hints_reload): Use do-while loop.
Alexei Podtelezhnikov 886f4d04 2015-04-01T22:57:43 [autofit] Finish the thought. * src/autofit/afhints.c (af_direction_compute): make sure the long arm is never negative so that its `FT_ABS' is not necessary.
Werner Lemberg a2fa657a 2015-04-01T15:55:41 [autofit] Call dumper functions for tracing. * src/autofit/afcjk.c (af_cjk_hints_apply): Remove dead code. * src/autofit/afhints.c (af_glyph_hints_dump_points): Minor improvement. * src/autofit/afmodule.c (af_autofitter_load_glyph): Implement it.
Werner Lemberg 16217e5f 2015-04-01T13:13:56 * src/autofit/afhints.c (af_glyph_hints_done): Fix minor thinko.
Werner Lemberg b57bb11a 2015-02-19T10:44:18 [autofit] Fix signedness issues. * src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afglobal.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aflatin2.c, src/autofit/afwarp.c, src/autofit/hbshim.c: Apply.
Werner Lemberg 81e5ff53 2015-02-19T09:46:48 [autofit] Use macros for (unsigned) flags, not enumerations. This harmonizes with other code in FreeType (and reduces the number of necessary casts to avoid compiler warnings). * src/autofit/afblue.hin: Make flag macros unsigned. * src/autofit/afblue.h: Regenerated. * src/autofit/afcjk.h: Replace flag enumeration with macros. * src/autofit/afcjk.c: Updated. * src/autofit/afhints.h (AF_Flags, AF_Edge_Flags): Replace with macros. * src/autofit/afhints.c: Updated. * src/autofit/aflatin.h: Replace flag enumerations with macros. * src/autofit/aflatin.c, src/autofit/aflatin2.c: Updated. * src/autofit/aftypes.h (AF_ScalerFlags): Replace with macros.
Werner Lemberg b6cb4997 2015-02-06T08:46:06 [autofit] Fix potential memory leak. While this doesn't show up with FreeType, exactly the same code leaks with ttfautohint's modified auto-hinter code (which gets used in a slightly different way). It certainly doesn't harm since it is similar to already existing checks in the code for embedded arrays. * src/autofit/afhints.c (af_glyph_hints_reload): Set `max_contours' and `max_points' for all cases.
Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
Behdad Esfahbod 56ddafa0 2015-01-14T19:36:02 [autofit] Add embedded array of segments and edges. Avoids multiple mallocs per typical glyphs. With this and recent changes to avoid mallocs, the thread-safe stack-based loader is now as fast as the previous model that had one cached singleton. * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED): New macros. (AF_AxisHintsRec): Add two arrays for segments and edges. * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate data if number of segments exceeds given threshold value. (af_axis_hints_new_edge): Only allocate data if number of edges exceeds given threshold value. (af_glyph_hints_done): Updated.
Behdad Esfahbod 6f16b100 2015-01-14T19:26:49 [autofit] Add embedded arrays for points and contours. This avoids at least two malloc calls for typical glyphs. * src/autofit/afhints.h (AF_POINTS_EMBEDDED, AF_CONTOURS_EMBEDDED): New macros. (AF_GlyphHintsRec): Add two arrays for contours and points. * src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done): Updated. (af_glyph_hints_reload): Only allocate data if number of contours or points exceeds given threshold values.
Werner Lemberg a632b5f4 2014-12-03T19:30:44 [autofit] Better fix for conversion specifiers in debug messages. Using `%ld' for pointer differences causes warnings on 32bit platforms. The correct type would be (the relatively new) `%td', however, this is missing on some important platforms. This patch improves the change from 2014-11-28. * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our pointer differences are always sufficiently small. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
suzuki toshiya 9ee6a0a0 2014-11-28T11:14:18 Fix compiler warning to conversion specifiers in debug messages. * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length modifier to dump long integers. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto.
Werner Lemberg 5b68e4fb 2014-09-24T19:06:13 [autofit] Minor clean-ups. * src/autofit/afhints.c (AF_FLAGS): Remove obsolete values. * src/autofit/afhints.c (af_glyph_hints_dump_points, af_glyph_hints_align_strong_points): Updated. * src/autofit/aflatin.c (af_latin_hints_link_segments, af_latin_hints_compute_segments), src/autofit/afcjk.c (af_cjk_hints_link_segments), src/autofit/aflatin2.c (af_latin2_hints_link_segments, af_latin2_hints_compute_segments): There are no longer fake segments since more than 10 years...
Werner Lemberg 387a9fe7 2014-09-22T06:42:24 [autofit] Minor code streamlining. * src/autofit/afhints.c (af_axis_hints_new_edge): Remove redundant initialization.
Werner Lemberg faa21472 2014-05-11T12:44:00 [autofit] Fix variable initializations. * src/autofit/afhints.c (af_glyph_hints_reload): Assign default values to `in_dir' and `out_dir' for all points.
Werner Lemberg 07e7b8af 2014-05-11T08:00:25 [autofit] Fix crash with font `CabinSketch-Bold.ttf'. Problem reported by Ralf S. Engelschall <rse@engelschall.com>. * src/autofit/afhints.c (af_glyph_hints_reload): Fix threshold for finding first non-near point. Properly initialize non-near point deltas.
Werner Lemberg 8a94b1ef 2014-04-12T20:44:33 [autofit] Redesign the recognition algorithm of strong points. In particular, local extrema without horizontal or vertical segments are better recognized: + A + D \ / \ / \ / \ / \ + C \ / B +/ If the distances AB and CD are large, point B wasn't previously detected as an extremum since the `ft_corner_is_flat' function `swallowed' BC regardless of its direction, tagging point B as weak. The next iteration started at B and made `ft_corner_is_flat' swallow point C, tagging it as weak also, et voilà. To improve that, another pass gets now performed before calling `ft_corner_is_flat' to improve the `topology' of an outline: A sequence of non-horizontal or non-vertical vectors that point into the same quadrant are handled as a single, large vector. Additionally, distances of near points are now accumulated, which makes the auto-hinter handle them as if they were prepended to the next non-near vector. This generally improves the auto-hinter's rendering results. * src/autofit/afhints.c (af_glyph_hints_reload): Implement it. * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag `AF_FLAG_NEAR'.
Werner Lemberg 7ac76b50 2014-03-04T04:29:17 Fix several clang static analyzer dead store warnings. * src/autofit/afhints.c (af_glyph_hints_reload, af_glyph_hints_align_weak_points): Remove unnecessary assignments. * src/bdf/bdflib.c (bdf_font_load): Ditto. * src/pshinter/pshalgo.c (psh_glyph_compute_extrema, psh_glyph_interpolate_other_points): Ditto. * src/type1/t1load.c (T1_Set_MM_Blend): Ditto.
Sean McBride 7be2a94a 2014-02-08T13:55:38 Fix clang static analyzer and compiler warnings. * src/autofit/afhints.c (af_glyph_hints_align_weak_points), src/autofit/afloader (af_loader_load_g) <FT_GLYPH_FORMAT_COMPOSITE>, src/base/ftcalc.c (FT_MSB), src/base/ftoutln.c (FT_Outline_Decompose), src/bdf/bdfdrivr.c (bdf_interpret_style), src/cff/cffparse.c (cff_parse_integer), src/cid/cidparse.c (cid_parser_new), src/pfr/pfrload.c (pfr_phy_font_load), src/raster/ftraster.c (Decompose_Curve), src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/ttcmap.c (tt_cmap12_next, tt_cmap13_next), src/smooth/ftgrays.c (gray_hline): Remove dead code. * src/autofit/afmodule.c (af_property_get_face_globals, af_property_set, af_property_get), src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Make functions static. * src/base/ftobjs.c (ft_remove_renderer): Protect against library == NULL. (ft_property_do): Make function static. * src/base/ftrfork.c: Include `ftbase.h'. * src/sfnt/ttsbit.c (tt_face_load_sbix_image) [!FT_CONFIG_OPTION_USE_PNG], src/type1/t1gload.c (T1_Compute_Max_Advance): Avoid compiler warning. * src/truetype/ttinterp.c (TT_New_Context): Reduce scope of variable.
Werner Lemberg 5c7f5500 2014-01-03T10:48:26 [autofit] Better ftgrid support. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add parameters `is_blue' and `blue_offset'.

Werner Lemberg 52166ab0 2013-11-27T10:10:16 [autofit] Fix use of dumping functions in `ftgrid' demo program. * src/autofit/afhints.c (AF_DUMP) [FT_DEBUG_AUTOFIT]: New macro. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges) [FT_DEBUG_AUTOFIT]: Add parameter to handle output to stdout. Use AF_DUMP. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges) [!FT_DEBUG_AUTOFIT]: Removed.
Werner Lemberg df41fe57 2013-08-05T16:34:32 Whitespace.
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 eed83061 2013-03-23T14:25:43 Whitespace.
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 b6978dd0 2012-07-06T19:38:44 [autofit] Do some code cleanup. * src/autofit/afglobal.c (af_face_globals_new): Simplify. * src/autofit/afhints.c: Use `FT_TRACE7' instead of `printf' everywhere. (FT_COMPONENT): New macro. (af_glyph_hints_done): Simplify. * include/freetype/internal/fttrace.h: Updated.
Werner Lemberg fd5ae959 2012-07-05T10:30:41 [autofit] Improve output of debugging information. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Print more data; report no data. (af_glyph_hints_dump_edges): Report no data.

Werner Lemberg 6b19fd5c 2011-05-30T07:27:59 Fix g++ 4.6 compilation. * src/autofit/afhints.c (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Use cast.
Daniel Zimmermann 3ad8f355 2011-05-24T06:22:32 Reduce warnings for MS Visual Studio 2010. * src/autofit/afhints.c (af_glyph_hints_get_num_segments, af_glyph_hints_get_segment_offset) [!FT_DEBUG_AUTOFIT]: Provide return value. * src/cff/cffgload.c (cff_slot_load): Add cast. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Use proper loop variable type.
Werner Lemberg 3a0844c8 2011-05-01T13:44:44 [autofit] Add more debugging functions. * src/autofit/afhints.c (af_glyph_hints_get_num_segments, af_glyph_hints_get_segment_offset): New functions.
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.

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
