3cc7d630 | 2006-09-27 08:48:38 | adding missing file | |
|
26bb2e27 | 2006-09-27 07:58:43 | * src/base/Jamfile, src/base/rules.mk, vms_make.com: adding 'ftlcdfil.c' to the list of compiled source files | |
|
8a317cf7 | 2006-09-27 07:52:48 | * include/freetype/freetype.h: bumping FT_FREETYPE_PATCH to 2 for an upcoming 2.2.2 release * include/freetype/ftlcdfil.h, src/freetype/ftlcdfil.c: 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 * src/smooth/ftsmooth.c: adding support for sub-pixel color filtering; simplifying a few function calls * include/freetype/config/ftheader.h: adding FT_LCD_FILTER_H macro that points to <freetype/ftlcdfil.h> | |
 |
e20df4a1 | 2006-09-27 06:29:21 | * src/pfr/pfrobjs.c (pfr_face_get_kerning): Skip adjustment bytes correctly. Reported as Savannah bug #17843. | |

e3d6e948 | 2006-09-26 16:58:21 | 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 ====================================================================== | |

(PCF_METRIC_SIZE, PCF_COMPRESSED_METRIC_SIZE, PCF_PROPERTY_SIZE): New macros which give the size of data structures in the data stream. (pcf_get_properties): Use rough estimates to get array size limits. Assign `face->nprops' and `face->properties' earlier so that a call to PCF_Face_Done can do the clean-up in case of error. Protect against invalid string offsets. (pcf_get_metrics): Clean up code. Adjust tracing message levels. Use rough estimate to get array size limit. (pcf_get_bitmaps): Clean up code.

|
c011f4cb | 2006-06-26 09:40:00 | The Type 1 parser now skips over top-level procedures as required for a `Simplified Parser'. This makes the parser more robust as it doesn't poke around in PostScript code. Additionally, it makes the FontDirectory hackery in src/type1/t1load.c unnecessary. * src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro. (skip_literal_string): Add FT_Error as return value. Handle escapes better. (skip_string): Add FT_Error as return value. Don't set `parser->error' but return error code directly. (skip_procedure): New function. (ps_parser_skip_PS_token): Handle procedures. Update code. (ps_parser_to_token): Update code. (ps_parser_load_field_table): Handle bbox entries also. * src/type1/t1load.c (parse_dict): Remove FontDirectory hackery. Add commented-out code for synthetic fonts. | |

9ca78256 | 2006-05-02 09:00:29 | * include/freetype/internal/ftmemory.h, src/base/ftbitmap.c, src/base/ftmac.c, src/base/ftrfork.c, src/lzw/ftzopen.c, 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. | |
|
264f307e | 2006-05-02 06:34:27 | * 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. | |
