        added a new API to support color filtering of subpixel glyph
        bitmaps. In default build, the function FT_Library_SetLcdFilter
        returns FT_Err_Unimplemented_Feature; you need to #define
        FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile
        the real implementation

        filtering; simplifying a few function calls

David Turner e3d6e94853 CHANGES BETWEEN 2.2.1 and 2.2.2
I. IMPORTANT BUG FIXES

    - Various integer overflows have been fixed.

    - PFB fonts with MacOS resource fork weren't  handled correctly on
      non-MacOS platforms.

    - The PCF font loarder has been seriously hardened against malformed
      font files.

  II. IMPORTANT CHANGES

    - the unpatented hinter is now part of the default build of the
      library, and we added code to automatically support "tricky"
      fonts that need it.

      what this means is that FreeType should "just work" with certain
      Asian fonts, like MingLiu, which cannot properly load without a
      bytecode interpreter, but fortunately do not use any of the
      patented bytecode opcodes.

      Note that the API didn't change, so you can still force
      unpatented hinting with a special parameter to FT_Open_Face
      as well.

      if you're an embedded systems developer, you might want to
      *disable* the feature to save code space by undefining
      TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h.

    - LCD-optimized rendering is now disabled in all default builds
      of the library, mainly due to patent reasons. For more information
      see:

      http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html

      a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has
      been introduced in ftoption.h; manually define it in this file
      if you want to re-enable the feature.

      the change only affects the implementation, not the FreeType API.
      This means that clients don't need to be modified, because the
      library still generates LCD decimated bitmaps, but with the added
      constraint that R=G=B on each triplet.

   - Some computation bugs in the TrueType bytecode interpreter were found,
     which allow us to get rid of very subtle and rare differences we had
     with the Windows renderer.

  III. MISCELLANEOUS

    - TrueType glyph loading is now about 25% faster.

    - the anti-aliased rasterizer has been optimized and is now 15% to 25%
      percent faster than the previous one, depending on content

    - the Type 1 loader has been improved; as an example, it now skips
      over top-level dictionaries properly

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

    src/raster/ftrend1.c, src/sfnt/ttpost.c, src/truetype/ttgxvar.c,
    src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
    against out-of-bounds conditions when allocating arrays. This is
    for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
    already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
    macros.
2006-05-02 09:00:29 +00:00
David Turner 264f307e66 * include/freetype/fterrdef.h, include/freetype/config/ftconfig.h,
include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
    src/base/ftutil.c: udpating the memory management functions and
    macros to safely deal with array size buffer overflows, this
    corresponds to attemps to allocate arrays that are too large. For
    an example, consider the following code:

         count = read_uint32_from_file();
         array = malloc( sizeof(Item) * count );
         for ( nn = 0; nn < count; nn++ )
           array[nn] = read_item_from_file();

    if 'count' is larger than FT_UINT_MAX/sizeof(Item), the multiplication
    will overflow and the array allocated will be smaller than the data
    read from the file. In this case, the heap will be trashed, and this
    can be used as a denial-of-service, or make the engine crash later.

    the FT_ARRAY_NEW and FT_ARRAY_RENEW macro now check that the new
    count is no more than FT_INT_MAX/item_size, otherwise, a new error,
    named 'FT_Err_Array_Too_Large' will be returned.

    note that the memory debugger now works again when FT_DEBUG_MEMORY
    is defined, and FT_STRICT_ALIASING has disappeared, the corresponding
    code being now the default.
