6689a009	2014-11-25T08:53:09	[Savannah bug #43682] Properly handle missing return errors. The functions in this patch do return non-trivial errors that must be taken care of. * src/autofit/afloader.c (af_loader_load_g), src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render), src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_endchar>, src/psaux/psobjs.c (ps_parser_load_field_table), src/psaux/t1decode (t1_decoder_parse_charstrings) <op_endchar>, src/truetype/ttgload.c (load_truetype_glyph <subglyph loop>, tt_loader_init, TT_Load_Glyph), src/truetype/ttgxvar.c (TT_Set_MM_Blend), src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Do it.
b24e8ba2	2014-11-25T08:30:49	[Savannah bug #43682] Add/remove `void' casts to some functions. We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it.

(FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated.
df485774	2014-11-19T21:21:23	Make `FT_Bitmap_Convert' correctly handle negative `pitch' values. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always use positive value for the pitch while copying data. Correctly set pitch sign in target bitmap.
d6061212	2014-11-19T21:13:23	Minor code improvement in `FT_Bitmap_Embolden'. * src/base/ftbitmap.c (FT_Bitmap_Embolden) <FT_PIXEL_MODE_GRAY[24]>: Fix thinko.

2e73a1b4	2014-11-09T23:22:43	[base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justifed by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept.

7abdb8cc	2014-10-02T23:13:33	[base] Significant optimization of `ft_div64by32' We shift as many bits as we can into the high register, perform 32-bit division with modulo there, then work through the remaining bits with long division. This optimization is especially noticeable for smaller dividends that barely use the high register. * src/base/ftcalc.c (ft_div64by32): Updated.
c0ce72a6	2014-10-02T06:44:43	Formatting.

7f49111f	2014-09-25T22:54:38	[base] Avoid unnecessary long division. This applies to `FT_MulDiv' but not to `FT_DivFix', where overflows or lack thereof are predicted accurately. * src/base/ftcalc.c (ft_div64by32): Improve readability. (FT_MulDiv, FT_MulDiv_No_Round) [!FT_LONG64]: Use straight division when multiplication stayed within 32 bits.
5c894842	2014-09-19T22:03:15	* src/base/ftcalc.c: Harmonize code.

f8efbcfb	2014-08-12T23:22:17	[base] Avoid undefined FT_MSB in `BBox_Cubic_Check'. * src/base/ftbbox.c (BBox_Cubic_Check): Update. (update_cubic_max): Repalce with... (cubic_peak): ... this, which now handles upscaling.
d2935e29	2014-08-12T00:41:04	* src/base/fttrigon.c (ft_trig_prenorm): Comment on undefined behavior.
28018d42	2014-08-12T00:26:16	[base] Handle collapsed outlines to avoid undefined FT_MSB. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Update.

e2d2b154	2013-12-27T16:44:24	[ftrfork] Fix the face order difference between POSIX and Carbon. The fragmented resources in Suitcase and .dfont should be reordered when post resource for Type1 is being restored, but reordering of sfnt resources induces the different face order. Now the ordering is restricted to post resource only, to prevent the different order issue (e.g. the face index in the fontconfig cache generated with Carbon framework is incompatible with that by FreeType2 without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung. http://lists.gnu.org/archive/html/freetype-devel/2013-02/msg00035.html http://lists.gnu.org/archive/html/freetype-devel/2013-12/msg00027.html * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Add a switch `sort_by_res_id' to control the fragmented resource ordering. * include/internal/ftrfork.h: Daclare new switch. * src/base/ftobjs.c (IsMacResource): Enable the soring for post resource, and disable the sorting for sfnt resource.
bd413862	2013-12-21T08:14:25	Fix PIC linking. * include/internal/ftrfork.h (CONST_FT_RFORK_RULE_ARRAY_BEGIN): Fix generated function name. * src/base/basepic.c (FT_Init_Table_raccess_guess_table): Rename to ... (FT_Init_Table_ft_raccess_guess_table): ... this so that the function name correctly corresponds to what the macro framework expects. * src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so that PIC functions are compiled also.
c4e968ed	2013-12-21T07:23:08	[base] Add missing dependencies to Makefile. * src/base/rules.mk (BASE_SRC): Add `basepic.c' and `ftpic.c'. (BASE_H): Add `basepic.h'.

28626869	2013-11-20T21:06:18	[truetype] Don't trust `maxp's `maxSizeOfInstructions'. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html for details. * src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep' tables also for setting `autohint'. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from `TT_Process_Composite_Glyph' for handling unreliable values of `maxSizeOfInstructions'.
fae38207	2013-11-13T08:55:46	Simplify header file hierarchy. This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/: Move up to... include/: ... this directory. builds/amiga/include/freetype/: Move up to... builds/amiga/include/: ... this directory. /: Essentially do `s@/freetype/@/@' where appropriate. CMakeList.txt: Simplify. * builds/unix/freetype-config.in, builds/unix/freetype2.in: For `--cflags', return a single directory. * builds/unix/install.mk (install): No longer try to remove `cache' and `internal' subdirectories; instead, remove the `freetype' subdirectory.
604838d5	2013-10-22T01:10:10	* src/base/md5.c, src/base/md5.h: Updated to recent version. * src/base/ftobjs.c: Updated; `md5.c' no longer uses `free'.
31e726d9	2013-09-20T07:20:53	Fix vertical size of emboldened glyphs. Cf. https://bugzilla.gnome.org/show_bug.cgi?id=686709 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Adjust `horiBearingY' also.
d689d1cf	2013-08-29T17:53:40	Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.

[ftrfork] Fix the face order difference between POSIX and Carbon. The fragmented resources in Suitcase and .dfont should be reordered when post resource for Type1 is being restored, but reordering of sfnt resources induces the different face order. Now the ordering is restricted to post resource only, to prevent the different order issue (e.g. the face index in the fontconfig cache generated with Carbon framework is incompatible with that by FreeType2 without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung. http://lists.gnu.org/archive/html/freetype-devel/2013-02/msg00035.html http://lists.gnu.org/archive/html/freetype-devel/2013-12/msg00027.html * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Add a switch `sort_by_res_id' to control the fragmented resource ordering. * include/internal/ftrfork.h: Daclare new switch. * src/base/ftobjs.c (IsMacResource): Enable the soring for post resource, and disable the sorting for sfnt resource.

[truetype] Don't trust `maxp's `maxSizeOfInstructions'. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html for details. * src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep' tables also for setting `autohint'. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from `TT_Process_Composite_Glyph' for handling unreliable values of `maxSizeOfInstructions'.

Simplify header file hierarchy. This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/*: Move up to... * include/*: ... this directory. * builds/amiga/include/freetype/*: Move up to... * builds/amiga/include/*: ... this directory. */*: Essentially do `s@/freetype/@/@' where appropriate. * CMakeList.txt: Simplify. * builds/unix/freetype-config.in, builds/unix/freetype2.in: For `--cflags', return a single directory. * builds/unix/install.mk (install): No longer try to remove `cache' and `internal' subdirectories; instead, remove the `freetype' subdirectory.

Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.

FT_Open_Face: Improve external stream handling. If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to... (open_face): This function.

Fix Savannah bug #39266. If memory allocations fail at certain points while opening a font, FreeType can either crash due to a NULL dereference or leak memory. * include/freetype/internal/ftobjs.c (FT_Face_InternalRec, FT_LibraryRec): Make `refcount' a signed integer. If, for example, FT_Open_Face() fails in a memory allocation before the face's reference count is set to 1, a subsequent `FT_Done_Library' call would otherwise loop over `FT_Done_Face' 2^32 times before freeing the face. * src/base/ftobjs.c (open_face): Initialize `stream' and friends earlier. (FT_Open_Face) <Fail>: Behave correctly if `node' is NULL. (FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.
