Werner Lemberg beb06395ff * doc/INSTALL.UNX: Cleaned up.
Other minor fixes/beautifying/formatting.
2003-04-21 13:30:27 +00:00
David Turner 2ff2bd8e2c * 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 7b80b45160 * 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 2471dd134d * 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 520f7b3d06 * 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 389a365b09 * 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 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.
2003-03-15 13:29:49 +00:00
David Turner 1ef648350e trying to fix TrueType rendering glitches 2003-03-14 07:31:35 +00:00
David Turner 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.
2003-03-13 21:07:51 +00:00
David Turner 7a50e76417 * 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 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 !!
2003-02-25 19:20:12 +00:00
David Turner 21493df9bd * 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 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
2003-02-18 22:25:22 +00:00
Graham Asher 343761601d Updated changelog: change to incremental interface. 2003-02-13 17:56:45 +00:00
David Turner 9f26ba72e7 * docs/CHANGES, docs/VERSION.DLL, docs/TODO: updating documentation for
the 2.1.4 release

    * builds/win32/visualc/freetype.dsp, builds/win32/visualc/index.html:
    updating the project file for 2.1.4
2003-01-31 10:12:40 +00:00
David Turner 7ca3b5e304 various improvements for 2.1.4. see ChangeLog, I've got problems with
copy & paste on my desktop !!

David Turner fa12012a5d updated documentation for 2.1.4 2003-01-24 08:30:36 +00:00
David Turner 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)
2003-01-22 22:53:55 +00:00
David Turner 4a1cdf133b * src/autohint/ahhint.c: small fix to the stem width optimisation 2003-01-22 22:47:04 +00:00
David Turner f041e82c89 * 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
Werner Lemberg c54198f04d * builds/unix/ltmain.sh: Regenerated with `libtoolize --force
--copy' from libtool 1.4.3.
* builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from
automake 1.7.1.
* builds/unix/configure: Regenerated with autoconf 2.54.
* builds/unix/config.guess, builds/unix/config.sub: Updated from
`config' CVS module at subversions.gnu.org.
* builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
`automake' CVS module at subversions.gnu.org.
2003-01-18 16:39:18 +00:00
David Turner 3277549456 * include/freetype/freetype.h: fixed documentation for FT_Size_Metrics 2003-01-15 23:43:17 +00:00
David Turner ebb0b2d9c5 * src/gzip/ftgzip.c: bugfix: couldn't read certain gzip-ed font files 2003-01-15 23:01:02 +00:00
David Turner f5d472025b * 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 e75d4cc6be Noted addition of 'const' to the first argument to FT_Matrix_Multiply. 2003-01-14 16:00:32 +00:00
Graham Asher a2b8e0b479 noted latest change to ttload.c 2003-01-13 10:27:35 +00:00
David Turner 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.

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 0fb0820fee * src/winfonts/winfnt.c: read 16 bytes into "reserved2", not "reserved" 2003-01-08 10:06:19 +00:00
David Turner 3f21842edc * 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 467e5d3e1e * 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 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 09:28:34 +00:00
David Turner a081e61ed5 * 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 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
2003-01-07 22:54:02 +00:00
David Turner c0cec09b11 updated builds/unix/configure by running autoconf 2002-12-26 21:49:40 +00:00
David Turner 3456045399 * 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 61fe2101d9 * 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 20:50:39 +00:00
David Turner 3303db53d4 * builds/unix/configure.ac, builds/unix/unix-cc.in,
builds/unix/unix-def.in: small fix to configure sub-system on Unix
        to allow other programs to correctly link with zlib when needed
2002-12-23 22:40:21 +00:00
David Turner 8116907221 * src/winfonts/winfnt.c: included George Williams' fix to support
version 2 fonts correctly
2002-12-18 22:53:12 +00:00
David Turner 9169587378 * 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 40587b66f7 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 7c53c0a766 * 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 45e31802ca Correct the name of the controlling macro (was __FTXF86_H__ ...) 2002-11-29 12:56:49 +00:00
David Turner 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.
2002-11-23 16:41:23 +00:00
David Turner 799af8843a * 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 ec8736da9e updating documentation & changes 2002-11-13 23:28:08 +00:00
David Turner 282e665f71 fixed a small bug in the sbit cache that caused problems with embedded bitmaps 2002-11-07 09:46:43 +00:00
David Turner 100317c335 * 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 6c99355440 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
