604838d5 | 2013-10-22 01:10:10 | * src/base/md5.c, src/base/md5.h: Updated to recent version. * src/base/ftobjs.c: Updated; `md5.c' no longer uses `free'. | |
 |
31e726d9 | 2013-09-20 07:20:53 | 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 | 2013-08-29 17:53:40 | 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. | |
 |
bd3849e7 | 2013-08-27 21:43:38 | 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. | |
|
bcd8c0b0 | 2013-08-27 21:36:03 | Remove `FT_SqrtFixed' function. It's no longer used. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c: Do it. | |

fc32e1c8 | 2013-08-19 22:57:05 | [base] Enable new algorithm for BBox_Cubic_Check. * src/base/ftbbox.c: Enable new BBox_Cubic_Check algorithm, remove the old one. Improve comments. | |
|
32a7d870 | 2013-08-17 22:19:21 | [base] Clean up BBox_Conic_Check. * src/base/ftbbox.c (BBox_Conic_Check): Remove redundant checks for extremum at the segment ends, which are already within the bbox. Slightly modify calculations. | |
|
1a9c3d14 | 2013-08-15 22:51:42 | [base] Finish experimental (disabled) BBox_Cubic_Check implementation. * src/base/ftbbox.c (BBox_Cubic_Check): Scale arguments to improve accuracy and avoid overflows. | |
|

e8ed2d62 | 2013-08-01 12:20:20 | Another round of cppcheck nitpicks. The call was (from the top-level of the FreeType tree): cppcheck --force \ --enable=all \ -I /usr/include \ -I /usr/local/include \ -I /usr/lib/gcc/i586-suse-linux/4.7/include \ -I include \ -I include/freetype \ -I include/freetype/config \ -I include/freetype/internal \ -DFT2_BUILD_LIBRARY \ . &> cppcheck.log using cppcheck git commit f7e93f99. Note that cppcheck still can't handle `#include FOO' (with `FOO' a macro). */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/gxvalid/*: Comment out redundant code or guard it with FT_DEBUG_LEVEL_TRACE. | |

 |
67cf7a88 | 2013-06-18 09:35:34 | 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. | |

dc624ca4 | 2013-06-04 10:30:48 | Apply fixes for cppcheck nitpicks. http://cppcheck.sourceforge.net/ Note that the current version heavily chokes on FreeType, delivering even wrong results. I will report those issues to the cppcheck team so that a newer version gives improved results hopefully. */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable): Remove unused variable. * src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero. * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate): Remove functionless code. * src/tools/ftrandom.c (main): Fix memory leak. | |

760d342d | 2013-05-29 11:36:18 | Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated. (ft_gray_for_premultiplied_srgb_bgra): New function. (FT_Bitmap_Convert): Handle FT_PIXEL_MODE_BGRA. * src/sfnt/pngshim.c, src/sfnt/pngshim.h: New files. * src/sfnt/sfnt.c: Include `pngshim.c'. * src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h' (tt_face_load_eblc): Load `CBLC'. (tt_sbit_decoder_init): Load `CBDT'. (tt_sbit_decoder_alloc_bitmap): Pass load flags to select between color and grayscale bitmaps. Set `num_grays'. This is used by `ftview' to choose the blending algorithm. (tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_image): Pass load flag. s/write/pwrite/.

89f50647 | 2013-03-14 17:50:49 | */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code. | |
|
059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |
|
c58ce3be | 2013-03-13 11:06:39 | Introduce `FT_THROW' macro. The idea is to replace code like return FT_Err_Foo_Bar; or return CFF_Err_Foo_Bar; with return FT_THROW( Foo_Bar ); The FT_THROW macro has two functions: . It hides the module specific prefix. . In debug mode, it calls the empty function `FT_Throw' which can be thus used to set a breakpoint. * include/freetype/internal/ftdebug.h (FT_THROW): New macro.

|
b4ac30b0 | 2013-01-02 22:21:37 | [base] Reduce trigonometric algorithms. After we get within 45 degrees by means of true 90-degree rotations, we can remove initial 45-degree CORDIC iteration and start from atan(1/2) pseudorotation, reducing expansion factor thereby. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macros. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Update. * src/tools/cordic.py: Bring up to date with trigonometric core. * docs/CHANGES: Old typo. | |
|
3ffb822e | 2012-12-21 16:45:27 | Check parameters of `FT_Outline_New'. Problem reported by Robin Watts <robin.watts@artifex.com>. * src/base/ftoutln.c (FT_Outline_New_Internal): Ensure that `numContours' and `numPoints' fit into FT_Outline's `n_points' and `n_contours', respectively. | |
|
d7383b7b | 2012-12-20 01:03:22 | [base] Improve trigonometric core. FreeType used to rely on a 24-step iteration CORDIC algorithm to calculate trigonometric functions and rotate vectors. It turns out that once the vector is in the right half-plane, the initial rotation by 63 degrees is not necessary. The algorithm is perfectly capable to converge to any angle starting from the second 45 degree rotation. This patch removes the first rotation and makes it a 23-step CORDIC algorithm. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro values. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial rotation. | |

|
8ac5c5c8 | 2012-12-15 23:33:55 | [base] Fix 11-year old bug. Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has always been slightly less than the correct value, which has been given in the comment as a hexadecimal. As a result, vector lengths were underestimated and rotated vectors were shortened. | |

c7c4d68b | 2012-01-17 15:13:50 | [raccess] Modify for PIC build. Based on the patch provided by Erik Dahlstrom <ed@opera.com>, http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()' are renamed with `ft_' suffixes. * src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed to `ft_raccess_rule_by_darwin_vfs()'. * src/base/ftobjs.c: Ditto. * src/base/ftrfork.c: Declarations of FT_RFork_Rule, raccess_guess_rec, are moved to... * include/freetype/internal/ftrfork.h: Here. * include/freetype/internal/ftrfork.h: FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined to replace raccess_guess_table[] in both of PIC and non-PIC modes. * src/base/ftrfork.c: raccess_guess_table[] array is rewritten by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}. * src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table' storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve the function pointer from `ft_raccess_guess_table' storage in `BasePIC' structure. * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with FT_RACCESS_GUESS_TABLE_GET.

3c966818 | 2012-01-15 23:35:31 | Fix redundant declaration warning in PIC mode. Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were designed to declare xxx_pic_{free,init} by themselves. Because these macros are used at the end of the module interface (e.g. ttdriver.c) and the wrapper source to build a module as a single object (e.g. truetype.c) includes the PIC file (e.g. ttpic.c) before the module interface, these macros are expanded AFTER xxx_pic_{free,init} body when the modules are built as single object. The declaration after the implementation causes the redundant declaration warnings, so the declarations are moved to module PIC headers (e.g. ttpic.h). Separating to other header files are needed for multi build. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): Remove class_##_pic_free and class_##_pic_init declarations. * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE): Ditto. * src/base/basepic.h: Insert a comment and fix coding style. * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, init}. * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, init}. * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, init}. * src/raster/rastpic.h: Declare ft_raster{1,5}_renderer_class_pic_{free,init} * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. * src/smooth/ftspic.h: Declare ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}. |
