David Turner 692bbe59da * src/base/ftmac.c (open_face_from_buffer): removed a double-free bug that
had nasty consequences when trying to open an "invalid" font on a Mac.
2003-04-09 07:03:38 +00:00
David Turner b6b6337539 * src/bdf/bdfdrivr.h, src/pcf/pcf.h: changed FT_Short to FT_UShort in
order to be able to access more than 32768 glyphs in fonts
2003-04-09 06:55:57 +00:00
David Turner e0ec6b3d53 * src/type1/t1load.c (T1_Open_Face): fixed the code to make it handle
special cases where a font only contains a ".notdef" glyph (happens in
   PDF-embedded fonts !!). Otherwise, FT_Panic was called !
2003-04-03 15:52:59 +00:00
David Turner 5158fbc03d * README: udpated
* README.UNX: removed (now replaced by docs/INSTALL.UNX)

   * src/pshinter/pshalgo3.c: the hinter now performs as in 2.1.3 and
   will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used

   * src/base/ftobjs.c: changed the default computations to include rounding
   in all cases, this is required to provide accurate kerning data when
   native TrueType hinting is enabled.

   * src/type1/t1load.c: the Type 1 loader now accepts more general names
   according to the Postscript spec (the previous one was too restrictive)
2003-03-27 21:35:44 +00:00
David Turner d6ec6eee78 * src/autohint/ahglyph.h, src/autohint/ahglyph.c, src/autohint/ahglobal.c,
src/autohint/ahhint.c: fixed blue-scale problem

    * src/cache/ftccache.c: fixed small bug that could crash the cache
    in rare circumstances (mostly with broken fonts)
2003-03-20 20:58:57 +00:00
David Turner 66cbc20978 * 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 1c044d7d29 * 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.

David Turner 562731d487 trying to fix TrueType rendering glitches 2003-03-14 07:31:35 +00:00
David Turner b280537b6d * 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.
2003-03-13 21:07:51 +00:00
David Turner a3c378024b * src/gzip/ftgzip.c (ft_gzip_file_done): fixed memory leak, the ZLib
stream was not properly finalized
2003-02-28 08:32:46 +00:00
David Turner b848b68274 reduce compiler warnings 2003-02-25 21:44:11 +00:00
David Turner fdc4600e5a reduce compiler warnings 2003-02-25 21:31:25 +00:00
David Turner ae26c684db * 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 229d122e92 * 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 !!

David Turner a41d3f056a * src/autohint/ahhint.c: disabled the advance width "correction" which
seemed to provide more trouble than benefits..
2003-02-18 22:36:04 +00:00
David Turner ba4511b807 * 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
2003-02-18 22:25:22 +00:00
Graham Asher 46960df7b3 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.
2003-02-13 17:49:27 +00:00
David Turner 4bdf4350f2 various improvements for 2.1.4. see ChangeLog, I've got problems with
copy & paste on my desktop !!
2003-01-30 23:24:18 +00:00
David Turner 032e23aab9 improvements to the Postscript hinter 2003-01-30 14:57:38 +00:00
David Turner 79c23ae28a * 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)
2003-01-22 22:53:55 +00:00
David Turner 146ff279b4 * src/autohint/ahhint.c: small fix to the stem width optimisation 2003-01-22 22:47:04 +00:00
David Turner 2f70965f9f * include/freetype/ftbdf.h, include/freetype/internal/bdftypes.h,
src/base/ftbdf.c, src/bdf/bdfdrivr.c, src/pcf/pcfdrivr.c,
    src/pcf/pcfread.h:

      adding a new API, named FT_Get_BDF_Property to retrieve the BDF
      properties of a given PCF or BDF font
2003-01-22 22:45:28 +00:00
David Turner 52e0a7e930 adding missing source file 2003-01-17 08:40:32 +00:00
David Turner 619d62d933 * src/gzip/ftgzip.c: bugfix: couldn't read certain gzip-ed font files 2003-01-15 23:01:02 +00:00
David Turner 12d09050f5 * include/freetype/config/ftheader.h, include/freetype/internal/fnttypes.h,
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
2003-01-15 22:48:27 +00:00
Graham Asher be1a8da313 Added 'const' to the first argument to FT_Matrix_Multiply. 2003-01-14 15:53:33 +00:00
Graham Asher 550fd43946 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.

David Turner 14018b4af9 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.

2003-01-11  David Turner  <david@freetype.org>

        * include/freetype/internal/fnttypes.h: fixed a structure field
        definition to avoid memory overwrites
2003-01-12 18:26:10 +00:00
David Turner 57ce0bee44 * src/winfonts/winfnt.c: read 16 bytes into "reserved2", not "reserved" 2003-01-08 10:06:19 +00:00
David Turner 77b68b8e73 * src/truetype/ttgload.c: fixing the TrueType loader to handle invalid
composites correctly by limiting the recursion depth
2003-01-08 09:59:17 +00:00
David Turner 265799a933 * src/autohint/ahtypes.h, src/autohint/ahhint.c, src/pshinter/pshalgo3.h,
src/pshinter/pshalgo3.c: implemented the FT_RENDER_MODE_LIGHT hinting
        mode in the auto and postscript hinters
2003-01-08 09:52:32 +00:00
David Turner 6453a819e8 * 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 09:28:34 +00:00
David Turner cce3c80c1f * Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: small changes to
support the compilation of FreeType 2 as part of larger projects with
        their own configuration options (only with Jam)
2003-01-08 09:10:53 +00:00
David Turner 20e33158da * 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
2003-01-07 22:54:02 +00:00
David Turner 8291d253b6 * src/gzip/adler32.c, src/gzip/infblock.c, src/gzip/inflate.c,
src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
        src/gzip/zutil.h: updates to allow compilation without compiler
        warnings with LCC-Win32

        * include/freetype/freetype.h, docs/VERSION.DLL,
        builds/unix/configure.ac: updates for the upcoming 2.1.4 release
2002-12-26 20:51:04 +00:00
David Turner caf4be3cd1 * src/winfonts/winfnt.c: included George Williams' fix to support
version 2 fonts correctly
2002-12-18 22:53:12 +00:00
David Turner c528f6fa41 * src/base/ftobjs.c (find_unicode_charmap): added some comments to
better explain what's happening there

        * src/base/ftobjs.c (open_face): included Graham Asher's fix to
        prevent faces without Unicode charmaps from loading
2002-12-18 22:43:07 +00:00
David Turner 621e488622 2002-12-16 David Turner <david@freetype.org>
* docs/VERSION.DLL: updating document to better explain the differences between
        the three version numbers being used on Unix, as well as provide the AutoConf
        fragment provided by Lars Clausen

        * src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
        prevented bezier arcs with negative vertical coordinates to be rendered
        appropriately


2002-11-27  Vincent Caron <v.caron@zerodeux.net>

        * builds/unix/unix-def.in, builds/unix/freetype-config.in,
        builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
        adding support for system zlib installations when available on the
        target platform (Unix only)
2002-12-16 21:51:24 +00:00
Antoine Leca c96f69dfaa * src/base/ftobjs.c: modified the logic to get Unicode charmaps.
Now it loads UCS-4 charmaps when there is one.
* src/base/ftobjs.c (find_unicode_charmap): new function.
* src/base/ftobjs.c (open_face): refer to the above one.
* src/base/ftobjs.c (FT_Select_Charmap): idem.
2002-12-03 00:39:16 +00:00
Antoine Leca c80e08c29c update of the script codes, according to the TAGS.txt file as distributed on Microsoft site.
This is preliminary, should be modified anyway.
2002-12-03 00:37:10 +00:00
David Turner 9967dce2b2 * 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.
2002-11-23 16:41:23 +00:00
David Turner c2278680e7 * src/cff/cffload.c (cff_charser_load): modified charset loader to
accept pre-defined charsets, even when the font contains fewer glyphs
2002-11-23 15:53:57 +00:00
David Turner 5237993a92 fixed a small bug in the sbit cache that caused problems with embedded bitmaps 2002-11-07 09:46:43 +00:00
David Turner e57ca7dec6 * src/otlayout/otlayout.h, src/otlyaout/otlconf.h,
src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c,
        src/otlayout/otlparse.h, src/otlayout/otlutils.h:

          updating the OpenType Layout code, adding support fot the first
          GSUB lookups. Nothing that really compiles for now though

        * src/autohint/ahhint.c: disabled serif stem width quantization. It
        produces slightly better shapes though this is not distinguishable
        with many fonts.
2002-11-07 01:36:29 +00:00
David Turner 60b32e16e7 2002-11-05 David Turner <david@freetype.org>
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
        support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
        the use of system-wide zlib.

        Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
        is not #undef-ed anymore. This allows the build system to define them
        depending on the configuration (typically by adding -D flags at
        compile time).

        * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
        in optimized mode relative to the "volatile" local variables. This was
        not a compiler bug after all, but the fact that a pointer to a volatile
        variable is not the same than a volatile pointer to a variable :-)

        the fix was to change  "volatile FT_Byte*  p"
        into                   "FT_Byte* volatile  p"

        * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
        compiler warnings in optimized modes

        * src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
        any zlib function names outside of the component. This prevents linking
        problems on some platforms, when applications want to link FreeType
        _and_ ZLib together.


2002-11-05  Juliusz  <jch@pps.jussieu.fr>

        * src/psaux/psobjs.c (ps_table_add): modified increment loop in
        order to implement exponential behaviour
2002-11-06 22:32:54 +00:00
David Turner 54b0bca50c * include/freetype/ftgzip.h, src/gzip/ftgzip.c:
adding support for gzip compressed streams !!

        * src/pcf/pcfdriver.c: adding automatic support for gzip-compressed
        PCF files
2002-10-31 22:19:27 +00:00
David Turner 3249c62523 * include/freetype/internal/internal.h, include/freetype/ftpfr.h,
src/base/ftpfr.c, src/base/Jamfile, src/descrip.mms, src/rules.mk,
        src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h:

        added PFR-specific public API. Fixed the kerning retrievel routine
        (it returned invalid values when the outline and metrics resolution
        differ)

        * src/base/ftsynth.c: fixed the synthetic emboldener. at last.

        * src/base/ftobjs.c: small internal fix to better support
        bitmap-based font formats
2002-10-31 08:30:19 +00:00
Werner Lemberg b4e18f1d6a Fix header comment. 2002-10-24 21:37:02 +00:00
Werner Lemberg eacb9306c0 Formatting; adding file headers. 2002-10-07 10:12:43 +00:00
Werner Lemberg c4c373cee5 * include/freetype/freetype.h (FT_Open_Face): Use `const' for `args'
(suggested by Graham).
* src/base/ftobjs.c (FT_Open_Face): Updated.
(ft_input_stream_new): Ditto.
2002-10-07 09:15:20 +00:00
