David Turner dbf3b43aea * 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)
2006-12-07 21:18:09 +00:00
David Turner 4060474815 - fixed a bug in af_compute_direction which generated ugly glyphs
- added more debug/log messages to help improve the auto-fitter
2006-11-02 16:37:35 +00:00
David Turner 65c7c773aa * src/autofit/afloader.c: removing superfluous code in the auto-fitter's
loader
2006-04-13 07:51:58 +00:00
David Turner 2ce9203735 - added FT_Get_SubGlyph_Info API to freetype.h
- small fix to lsb/rsb delta computations
- cleaning up Jamfile

David Turner dad2a2de01 * 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.

Wu, Chia-I (吳佳一) 2e48a1a138 * src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics, FT_Load_Glyph):
Re-enable glyph metrics grid-fitting.  It is now done in the base
layer.
(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) 4cdb45c01e Introduce experimental autofit CJK module based on akito's autohint
patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.

* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
Add CJK module based on akito's autohint patch.

* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
overlap length of the segments.  (AF_SEGMENT_LEN, AF_SEGMENT_DIST):
New macros.

* src/autofit/aflatin.h (af_latin_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'.
Use the character given by the caller.
(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
the thresholds.

* src/autofit/afloader.c (af_loader_load_g): Respect
AF_SCALER_FLAG_NO_ADVANCE.

shadowing variable declarations.
Fix warning parameters and replace printf with AF_LOG.
(af_warper_compute): Remove unused variable.
2006-01-22 07:09:54 +00:00
Werner Lemberg 1be9ebf5f9 * src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c.

David Turner bb4edc9235 * 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.

    with certain fonts.
2005-03-01 22:49:32 +00:00
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

2005-03-01 15:48:29 +00:00

  heap-optimized embedded bitmap loader. This one also fixes bug #12107

  * src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without
  a 'kern' table.
2005-02-28 22:09:07 +00:00
David Turner 8530a22888 * 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

`rsb_delta' in slot->metrics and tune side bearings slightly.
2004-06-05 06:27:08 +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
David Turner 10bf05a31d * 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
2004-04-21 14:30:37 +00:00
Werner Lemberg 8bb07e6386 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.
2004-03-27 08:43:17 +00:00
David Turner 9bfbf79c9f adding support for dummy script, i.e. no-hinting for non latin glyphs 2004-02-23 21:08:37 +00:00
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
Werner Lemberg 6b3d00e1a0 * 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.
2004-02-03 21:34:29 +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..
