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_.

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?)

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.

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.

* src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c
    (ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): changed the
    syntax of the FT2_DEBUG environment variable  used to control debugging
    output (i.e. logging and error messages). It must now look like:

       any:6 memory:4 io:3   or
       any:6,memory:4,io:3   or

2a4fa1340e * include/freetype/ftxf86.h, src/base/ftxf86.c: added a new API named
FT_Get_X11_Font_Format to return an X11-compatible string describing the
    font format of a given face. This was put in a new optional base source
    file, corresponding to a new public header (named FT_XFREE86_H since
    this function should only be used within the XFree86 font server IMO).

    * include/freetype/config/ftheader.h: adding FT_XFREE86_H, though it's
    not documented yet.

    * include/freetype/t1tables.h, src/base/fttype1.c: adding two new APIs
    named "FT_Get_PS_Font_Info" and "FT_Has_PS_Glyph_Names". This required
    a new optional source in 'src/base' named "fttype1.c"

    * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: updating
    build control files for the new files "ftxf86.c" and "fttype1.c" in
    src/base

791d83a612 * include/freetype/internal/tttypes.h, src/sfnt/ttload.c,
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
        fixing the SFNT name table loader to support various buggy fonts.
        it now ignores empty name entries, entries with invalid pointer
        offsets and certain fonts containing tables with broken "storageOffset"
        fields.

        name strings are now loaded on demand, which reduces the memory
        requirements for a given FT_Face tremendously (for example, the
        name table of Arial.ttf is about 10Kb and contains 70 names !!)

        finally, this is a _quick_ fix. The whole name table loader and
        interface will be rewritten in a much more cleanly way shortly,
        once CSEH have been introduced in the sources.
