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.

David Turner bb076bd0fb cosmetic + typo fixes 2002-09-11 06:13:09 +00:00
David Turner 25f845aa64 * src/cache/ftccache.i: fixed a bug that prevented compilation in
debug mode of template instantiation

        * src/cff/cffparse.c: fixed the CFF table loader. It didn't accept
        empty arrays, and this prevented the loading of certain fonts.

        * src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to
        prevent seg fault when hints are provided in an empty glyph !!

        * include/freetype/ftimage.h: removed incorrect "zft_" definitions
        and updated constants documentation comments

        * include/freetype/freetype.h (FT_FaceRec): updating documentation
        comment. The "descender" value is always *negative*, not positive !

        * include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
        src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
        rendering correctly. Definition of FTC_ImageTypeRec that replaces the
        obsolete FTC_ImageDesc, and has slightly different fields. The
        image type is now determined directly by "load_flags" values.

        * src/autohint/ahtypes.h, src/autohint/ahhint.c,
        src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
        to the automatic and Postscript hinters !! and sub-pixel hinting now
        works correctly (see demo programs)

    the erroneous FT_ENCODING_SYMBOL)

    * builds/unix/unix-def.in: added "datadir" definition
    (thanks to Anthony Fok)
2002-09-04 19:58:47 +00:00
David Turner d1245c0dd2 updating sources to support the new FT_LOAD_TARGET_ constants
to support target-specific hinting
2002-08-27 22:34:20 +00:00
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_.

        and removing compiler warnings
2002-08-21 22:06:41 +00:00
David Turner f467e6a93f * include/freetype/freetype.h, src/base/ftobjs.c: changing the type
of the "load_flags" parameter of FT_Load_Glyph and FT_Load_Char from
        "FT_Int" to "FT_Int32", this in order to support more options.

        this should only break binary and/or source compatibility on
        16-bit platforms (Atari?)

Graham Asher ce12182cfc Modified incremental loading interface to be closer to David Turner's
preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.
2002-08-01 15:29:17 +00:00
David Turner 76effc302f * include/freetype/ftincrem.h: adding new experimental header file

David Turner 7acd73fd6a * src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttdriver.c: changing
the SFNT loader to check for SFNT-based font files differently. We now
    ignore the range "helper" fields and check the "head" table's magic
    number instead.
