c7fd9356	2014-10-30T22:43:01	[smooth] Fix Savannah bug #35604 (cont'd). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove checks and casts that became unnecessary after the variable type upgrades.
465ab995	2014-10-29T23:45:23	[smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code.

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.
9a7951d9	2013-07-16T15:25:24	[smooth] Fix segfault caused by previous commit. * src/smooth/ftgrays.c (gray_set_cell): Always compute `ras.invalid'.
89929ec6	2013-07-16T13:36:07	[smooth] Improve performance. Provide a work-around for an ARM-specific performance bug in GCC. This speeds up the rasterizer by more than 5%. Also slightly optimize `set_gray_cell' and `gray_record_cell' (which also improves performance on other platforms by a tiny bit (<1%). * src/smooth/ftgrays.c (FT_DIV_MOD): New macro. Use it where appropriate. (gray_record_cell, gray_set_cell, gray_move_to, gray_convert_glyph_inner): Streamline condition handling.
d7e3444b	2013-06-14T18:33:39	* src/smooth/ftgrays.c One final pragma to silence 64-bit MSVC.
45392b77	2013-06-05T13:43:20	Fix compiler warnings. * include/freetype/internal/ftmemory.h: Decorate memory allocation macros with `FT_Long' where appropriate. Remove duplicate of FT_MEM_QRENEW_ARRAY definition. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Use cast. * src/base/ftobjs.c: Add warning disabling pragma for MSVC while including `md5.c'. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdESC>: Add cast. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_compound): Fix casts. (tt_sbit_decoder_load_bitmap): Beautification. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Initialize variables (earlier). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Pacify compiler. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Use unsigned constants where appropriate. * src/type1/t1load.c (T1_Get_MM_Var): Ditto.
dc624ca4	2013-06-04T10:30:48	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.

e3c93015	2013-03-14T11:21:17	/: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335	2013-03-14T10:27:35	/: 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.
4cd5fd46	2013-01-24T13:33:06	Remove trailing whitespace.
fdcbaf19	2012-10-21T10:40:12	[smooth] Improve tracing. * src/smooth/ftgrays.c (gray_sweep): Trace last sweep line of current band also.
328aa3b2	2012-08-27T11:23:41	[FT_CONFIG_OPTION_PIC] Fix g++ 4.6.2 compiler warnings. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER), include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE), include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC1, FT_DEFINE_SERVICEDESCREC2, FT_DEFINE_SERVICEDESCREC3, FT_DEFINE_SERVICEDESCREC4, FT_DEFINE_SERVICEDESCREC5, FT_DEFINE_SERVICEDESCREC6), src/autofit/afpic.c (autofit_module_class_pic_init), src/base/basepic.c (ft_base_pic_init), src/base/ftinit.c (ft_create_default_module_classes), src/cff/cffparse.c (FT_Create_Class_cff_field_handlers), src/cff/cffpic.c (cff_driver_class_pic_init), src/pshinter/pshpic.c (pshinter_module_class_pic_init), src/psnames/pspic.c (psnames_module_class_pic_init), src/raster/rastpic.c (ft_raster1_renderer_class_pic_init), src/sfnt/sfntpic.c (sfnt_module_class_pic_init), src/sfnt/ttcmap.c (FT_Create_Class_tt_cmap_classes), src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init), src/truetype/ttpic.c (tt_driver_class_pic_init): Initialize allocation variable.

1749d8bc	2012-01-17T02:00:24	Remove trailing spaces.
c24f77ac	2012-01-16T21:13:05	Formatting PIC related sources. * src/autofit/afpic.c: Harmonize to FT2 coding conventions. * src/base/basepic.c: Ditto. * src/base/ftpic.c: Ditto. * src/cff/cffpic.c: Ditto. * src/pshinter/pshpic.c: Ditto. * src/psnames/pspic.c: Ditto. * src/raster/rastpic.c: Ditto. * src/sfnt/sfntpic.c: Ditto. * src/smooth/ftspic.c: Ditto. * src/truetype/ttpic.c: Ditto.
3c966818	2012-01-15T23:35:31	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}.
4b733517	2012-01-14T06:32:50	Make PIC files to include module error headers, to use the error codes with per-module prefix. * src/autofit/afpic.c: Include `aferrors.h'. * src/cff/cffpic.c: Include `cfferrs.h'. * src/pshinter/pshpic.c: Include `pshnterr.h'. * src/raster/rastpic.c: Include `rasterrs.h'. * src/sfnt/sfntpic.c: Include `sferrors.h'. * src/smooth/ftspic.c: Include `ftsmerrs.h'. * src/truetype/ttpic.c: Include `tterrors.h'.

8fb88414	2011-03-17T20:24:57	A better fix for Savannah bug #32671. * src/smooth/ftgrays.c (gray_render_conic): Clean up code and replace WHILE loop with a more natural DO-WHILE construct.
6c045535	2011-03-07T05:40:42	Quick fix for Savannah bug #32671. This isn't the optimal solution yet, but it restores the previous rendering quality (more or less). * src/smooth/ftgrays.c (gray_render_conic): Do more splitting.
f3ce2370	2011-01-03T07:11:54	/rules.mk: Handle `pic.c' files.

6aee6909	2010-11-02T16:01:03	[ftsmooth] Improve rendering. * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3, cubic deviations have been estimated _after_ UPSCALE, whereas conic ones have been evaluated _before_ UPSCALE, which produces inferior rendering results. Fix this. Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has been tested with demo images sent to the mailing list. See http://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html and later mails in this thread.
34d61e86	2010-10-15T20:44:15	Fix thinko in spline flattening. FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and replace it everywhere with ONE_PIXEL/8.
0e6fc091	2010-10-02T09:05:46	[smooth] Fix splitting of cubics for negative values. Reported by Róbert Márki <gsmiko@gmail.com>; see http://lists.gnu.org/archive/html/freetype/2010-09/msg00019.html. * src/smooth/ftgrays.c (gray_render_cubic): Fix thinko.
e0a9a933	2010-09-20T09:29:23	[smooth] Fix and improve spline flattening. This fixes the flattening of cubic, S-shaped curves and speeds up the handling of both the conic and cubic arcs.

6305b869	2010-06-30T18:24:33	Fix Savannah bug #30263. * src/smooth/ftgrays.c (gray_render_span): Use cast to `unsigned int' to avoid integer overflow. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller threshold values for `width' and `height'. This is not directly related to the bug fix but makes sense anyway.
e419f48b	2010-06-24T12:50:46	* src/smooth/ftgrays.c (gray_render_cubic): Fix algorithm. The previous version was too aggressive, as demonstrated in http://lists.gnu.org/archive/html/freetype-devel/2010-06/msg00020.html.

c1e22f39	2009-04-05T18:14:04	Position Independent Code (PIC) support in smooth renderer. * src/smooth/ftsmooth.h declare ft_smooth_renderer_class, ft_smooth_lcd_renderer_class and ft_smooth_lcd_v_renderer_class using macros from ftrender.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/smooth/ftsmooth.c when FT_CONFIG_OPTION_PIC is defined the following structs: ft_smooth_renderer_class, ft_smooth_lcd_renderer_class and ft_smooth_lcd_v_renderer_class will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from ftspic.h in order to access ft_grays_raster from the pic_container (allocated in ftgrays.c). * src/smooth/ftgrays.h include FT_CONFIG_CONFIG_H * src/smooth/ftgrays.c when FT_CONFIG_OPTION_PIC is NOT defined func_interface was moved from gray_convert_glyph_inner function to the global scope. When FT_CONFIG_OPTION_PIC is defined func_interface and ft_grays_raster structs will have functions to init them instead of being allocated in the global scope. And func_interface will be allocated on the stack of gray_convert_glyph_inner. New Files: * src/smooth/ftspic.h declare struct to hold PIC globals for smooth renderer and macros to access them. * src/smooth/ftspic.c implement functions to allocate, destroy and initialize PIC globals for smooth renderer. * src/smooth/smooth.c add new file to build: ftspic.c. * src/smooth/jamfile add new files to FT2_MULTI build: ftspic.c.

ce33a312	2008-12-21T10:29:30	FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE.

e3d6e948	2006-09-26T16:58:21	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 ======================================================================
36d2eab0	2006-09-05T19:24:34	* src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size' values which have the upper two bytes set to 0xFF instead of 0xFF (as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and `HAN NOM B.ttf'). * src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code. Formatting.

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.

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}.

FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE.

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 ======================================================================
