       which filter to apply, new values FT_LCD_FILTER_LIGHT and
       FT_LCD_FILTER_LEGACY (the latter implements the LibXft original

        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%.

        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.

`AF_Dimension' but `int' for loop counter.

`AF_Dimension' but `int' for loop counter.
Use proper enumeration value for `render_mode'.
(af_latin_metrics_scale_dim): Don't shadow variables.
(af_latin_hints_compute_segments): Use proper cast for `major_dir'
and `segment_dir'.
(af_latin_align_linked_edge, af_latin_hint_edges): Fix arguments of call to
`af_latin_compute_stem_width'.
(af_latin_hints_apply): Don't use `AF_Dimension' but `int' for loop
counter.

proper cast for memory allocation.

* src/cff/cffdrivr.c (cff_get_kerning): Use proper cast for
initialization of `sfnt'.

David Turner b9c22aff61 * src/autofit/{afhints.h,afhints.c,aflatin.h,aflatin.c,afloader.c}:
various bug-fixes and drastic heap usage reduction improvements.

    * include/freetype/config/ftmodule.h: the auto-fitter is now the
    only supported auto-hinting module

    * include/freetype/config/ftstdlib.h: adding FT_INT_MAX definition
2005-03-01 15:48:29 +00:00
David Turner e664efaddd * 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
2004-06-04 17:41:59 +00:00
Werner Lemberg 8bb07e6386 Add vertical phantom 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.

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.



Add support for PCF fonts compressed with LZW (extension .pcf.Z,
created with `compress').

David Turner 1029ed26af * 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 !!
2004-02-23 20:40:30 +00:00
David Turner f546bacdcf * 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..
