956884724d * docs/*: serious rewriting of the documentation
* include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c,
    src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c,
    src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions
    to deal with glyph bitmaps within FT_GlyphSlot objects. these are:

      ft_glyphslot_free_bitmap
      ft_glyphslot_alloc_bitmap
      ft_glyphslot_set_bitmap

    these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
    flag manually. the font drivers have been modified to use them as well.

    * src/cache/ftlru.c: fixed an invalid assertion check
2003-03-20 07:04:40 +00:00
David Turner
8a4f0e3d73 * src/truetyoe/ttdriver.c (Set_Char_Sizes): fixed a small rounding bug.
Actually, it seems that previous versions of FreeType didn't perform
    TrueType rounding exactly as appropriate.

ad1ceca2a5 * src/base/ftdbgmem.c, docs/DEBUG.TXT: added new environment variables
to control memory debugging with FreeType. See the description of
    "FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX"
    in DEBUG.TXT

    * src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c,
    ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory
    conditions.

    * src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a
    small memory leak

    * src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that
    only happened when trying to resize an array would end in an OOM.

    * src/smooth/ftgrays.c: removed compiler warnings / volatile bug

    * src/truetype/ttobjs.c: removed segmentation fault that happened in
    tight memory environments.

stream was not properly finalized

0ba973dadf * src/cache/ftccmap.c: the cmap cache now supports UCS-4 charmaps
when available in Asian fonts

    * src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in
    comments

    * src/truetype/ttdriver.c (Set_Char_Sizes): fixed a rounding bug when
    computing the scale factors for a given character size in points with
    resolution.
2003-02-25 20:37:50 +00:00
David Turner
fd37c4b8ac * src/gzip/ftgzip.c: fixed a bug that caused FreeType to loop endlessly
when trying to read certain compressed gzip files. The following test
    could be used to reveal the bug:

       touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz


    * src/pfr/pfrobjs.c, src/pfr/pfrload.c, src/pfr/pfrtypes.h: several
    fixes to the PFR font driver:

      - the list of available embedded bitmaps was not correctly set
        in the root FT_FaceRec structure describing the face

      - the glyph loader always tried to load the outlines when
        FT_LOAD_SBITS_ONLY was specified

      - the table loaded now scans for *undocumented* elements of a
        physical font's auxiliary data record, this is necessary to
        retrieve the "real" family and style names.

        NOTE THAT THIS CHANGES THE FAMILY NAME OF MANY PFR FONTS !!

21493df9bd * src/autohint/ahhint.c: disabled the advance width "correction" which
seemed to provide more trouble than benefits..

7946aa6f7b * src/truetype/ttdriver.c, src/truetype/ttobjs.h, src/truetype/ttobjs.c,
src/truetype/ttinterp.c, src/base/ftobjs.c: fixing the slight distortion
    problem that occured due to the latest auto-hinter changes

343761601d Updated changelog: change to incremental interface. 2003-02-13 17:56:45 +00:00
Graham Asher
09495b4acf The incremental interface now passes the old metrics when asking for
replacement metrics so that they can be modified, not just replaced.
For example, CFF fonts need this.

fb2bcfc594 * src/sfnt/ttload.c (sfnt_dir_check): relaxed the "head" table size
verification to accept a few broken fonts who pad the size incorrectly
    (the table should be padded, but its "size" field shouldn't per se
     the spec)

include/freetype/ftwinfnt.h, src/base/winfnt.c, src/winfonts/winfnt.c,
    src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:

      added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty
      bug in the header loader which would cause invalid memory overwrites

4c157cd023 TrueType typefaces lacking hmtx (horizontal metrics) tables are tolerated if the
incremental interface system is enabaled and an incremental interface
has been specified. This is necessary to support some typefaces passed
from GhostScript.

7f0c4e9cc2 2003-01-11 David Chester <davidchester@qmx.net>
* include/freetype/config/ftoption.h, src/autohint/ahglobal.h,
        src/autohint/ahglobal.c, src/autohint/ahglyph.c,
        src/autohint/ahtypes.h:

          included David Chester's patches to the auto-hinter in order to
          slightly improve the output. Note that everything is controlled
          through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the
          end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX
          macros to control individual "features".

          Note that all improvements are enabled by default, but can be
          tweaked for optimization and testing purpose. The configuration
          macros will most likely disappear in the short future.

        * include/freetype/internal/fnttypes.h: fixed a structure field

bd23b2d9c7 * src/base/ftobjs.c (find_unicode_charmap): fixed the error code
returned when the font doesn't contain a Unicode charmap. This
        allows FT2 to load "symbol.ttf" and a few others correctly since
        the last release

2003-01-08 09:10:53 +00:00
David Turner
ad13f8270e * src/base/ftstroker.c: probably the last bug-fixes to the stroker,
the API is likely to change however.

        * src/base/fttrigon.c (FT_Angle_Diff): fixing function, it returned
        invalid values for large negative angle differences (resulting in
        incorrect stroker computations, among other things)

        * src/cache/ftccache.c (ftc_node_unlink): removing incorrect
        assertion, and changing code to avoid hash table size contraction

        * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
        adding "ftstroker.obj" to default build, as optional component

        fragment provided by Lars Clausen

        * src/smooth/ftgrays.c (gray_render_conic): fixed small bug that

        * builds/unix/unix-def.in, builds/unix/freetype-config.in,

Now it loads UCS-4 charmaps when there is one.
* src/base/ftobjs.c (find_unicode_charmap): new function.

53bb57b55d * src/cff/cffload.c (cff_charser_load): modified charset loader to
accept pre-defined charsets, even when the font contains fewer glyphs.
        also enforced more checks to ensure that we never overflow the
        character codes array in the encoding.
