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 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.

David Turner fdc4600e5a reduce compiler warnings 2003-02-25 21:31:25 +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 !!

copy & paste on my desktop !!

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 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 eacb9306c0 Formatting; adding file headers. 2002-10-07 10:12:43 +00:00
David Turner 80171e06dd * src/pfr/pfrsbit.h, src/pfr/pfrsbit.c, src/pfr/pfrload.c,
src/pfr/pfrgload.c, src/pfr/pfrobjs.c, src/pfr/pfrtypes.h,
        Jamfile, src/base/ftobjs.c: adding support for embedded bitmaps to
        the PFR driver, and rewriting its kerning loader / handler to use all
        kerning pairs in a physical font (and not just the first item).

        * src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
        src/tools/docmaker/tohtml.py: fixing a few nasty bugs

        * src/sfnt/ttcmap0.c: the validator for format 4 sub-tables is
        now capable of dealing with invalid "length" fields at the start
        of the sub-table. This allows fonts like "mg______.ttf" (i.e.
        Marriage) to return accurate charmaps.

David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
    transformations of the sources:

      - trying to convert all enums and constants to CAPITALIZED_STYLE, with
        #define definitions like

          #define  my_old_constants   MY_NEW_CONSTANT

      - big, big update of the documentation comments

    * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
    include/freetype/ftimage.h: adding support for LCD-optimized rendering
    though the new constants/enums:

      FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
      FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

    this is still work in progress, don't expect everything to work correctly
    though most of the features have been implemented.

    * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
    targets:

      FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
      FT_LOAD_TARGET_MONO   :: monochrome bitmaps
      FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated hinting & rendering
      FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated hinting & rendering

    note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
    behaviour of the font engine is _unchanged_.
