suzuki toshiya 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.
suzuki toshiya 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}.
suzuki toshiya 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'.

Werner Lemberg e9e93d1b 2011-09-17T09:21:25 [smooth] Slightly optimize conic and cubic flatterners. * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move out some code from the main loop to speed it up.
Werner Lemberg 71cc1a83 2011-05-30T07:20:37 Fix gcc 4.6 compiler warnings. * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Use casts and remove unused variables. * src/autofit/aflatin.c (af_latin_hints_compute_edges): Comment out `up_dir'. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use `height_org' and `width_org' conditionalized.

Werner Lemberg 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.
Werner Lemberg f3ce2370 2011-01-03T07:11:54 */rules.mk: Handle `*pic.c' files.

Alexei Podtelezhnikov 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.
Werner Lemberg 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.
Werner Lemberg 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.
Graham Asher 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. See the discussions on the freetype-devel mailing list in late August and September 2010 for details. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.

Werner Lemberg 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.
Graham Asher 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.
Werner Lemberg f765e440 2010-06-24T10:34:29 */*: Use module specific error names where appropriate.

Oran Agra 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.

Werner Lemberg 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.

David Turner 8a317cf7 2006-09-27T07:52:48 * 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>

David Turner 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 ======================================================================
Werner Lemberg 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.

David Turner 772e55d3 2006-09-05T09:45:15 * src/smooth/ftgrays.c (gray_sweep): Avoid buffer overwrites when to the end of a bitmap scanline. The fun never ends ;-)
David Turner aa557a90 2006-09-04T16:42:44 fix for the latest rasterizer optimization

David Turner de271ab8 2006-02-25T14:53:02 * builds/unix/ftsystem.c, include/freetype/config/ftheader.h, include/freetype/internal/services/svotval.h, include/freetype/internal/services/svpfr.h, src/base/ftsystem.c, src/bdf/bdfdrivr.c, src/cache/ftcbasic.c, src/cff/cffcmap.c, src/gzip/ftgzip.c, src/lzw/ftlzw.c, src/lzw/ftlzw2.c, src/psaux/t1cmap.c, src/sfnt/ttbdf.c, src/smooth/ftgrays.c: solved -Wmissing-prototypes warnings with GCC
Werner Lemberg 59939244 2006-01-31T20:17:42 Implement new, simplified module selection. With GNU make it is now sufficient to modify a single file, `modules.cfg', to control the inclusion of modules and base extension files. This change also fixes the creation of ftmodule.h; it now depends on `modules.cfg' and thus is rebuilt only if necessary. Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the default location. * modules.cfg: New file. * builds/freetype.mk: Don't include `modules.mk'. Include all `rules.mk' files as specified in `modules.cfg'. (FTOPTION_FLAG, FTOPTION_H): New variables. (FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H. Add FTOPTION_FLAG. ($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST. (CONFIG_H): Add FTMODULE_H and FTOPTION_H. (INCLUDES): Add DEVEL_DIR. (INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ, OBJ_M, OBJ_S): Use `:=', not `='. (remove_ftmodule_h): New phony target to delete `ftmodule.h'. (distclean): Add remove_ftmodule_h. * builds/modules.mk: (MODULE_LIST): Removed. (make_module_list, clean_module_list): Replace targets with... (FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New variables. Reason for the change is that it is not possible to have a phony prerequisite which is run only if the target file must be rebuilt (phony prerequisites act like subroutines and are *always* executed). We only want to rebuild `ftmodule.h' if `module.cfg' is changed. Update all callers. ($FTMODULE_H)): Rule to create `ftmodule.h', depending on `modules.cfg'. * builds/toplevel.mk: Rewrite and simplify module handling. (MODULES_CFG, FTMODULE_H): New variables. Include MODULES_CFG. (MODULES): New variable to include all `module.mk' and `rules.mk' files. We no longer use make's `wildcard' function for this. * Makefile (USE_MODULES): Remove. Update all users. (OBJ_DIR): Define it here. * src/*/module.mk: Change make_module_list: foo foo: ... to FTMODULE_H_COMMANDS += FOO define FOO ... endef in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'. * src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS. * builds/unix/detect.mk (setup): Always execute `configure' script. (have_mk): Rename to... (have_Makefile): This. Don't use `strip' function. * builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is defined. (have_mk): Don't use `strip' function. Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test accordingly). * builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'. * builds/os2/os2-dev.mk, builds/unix/unix-dev.mk, builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. * builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR), builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in (TOP_DIR, OBJ_DIR): Removed. Defined elsewhere. * builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR), builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere. * builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. Don't define PLATFORM. * configure: Copy `modules.cfg' to builddir if builddir != srcdir. Update snippet taken from autoconf's m4sh.m4 to current CVS version. Be more verbose. * include/freetype/config/ftmodule.h: Add comments -- this file is no longer used if FreeType is built with GNU make. * docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY, docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism. Other minor updates. * modules.txt: Removed. Contents included in `modules.cfg'. * include/freetype/internal/ftmemory.h (FT_QAlloc_Debug, FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos. * src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug, FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug) [FT_STRICT_ALIASING]: Implement.
Werner Lemberg 7596fd3a 2006-01-28T16:29:29 * src/*/module.mk (.PHONY): Add.
Werner Lemberg f6a25503 2006-01-28T10:38:15 * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. * src/autofit/module.mk (add_autofit_module), src/bdf/module.mk (add_bdf_module), src/type42/module.mk (add_type42_driver): Fix whitespace. * src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv renderer classes.

Werner Lemberg 858f310b 2003-06-09T04:46:30 Completely revised FreeType's make management. . In all makefiles `/' is used as the path separator. The conversion to the real path separators is done as late as possible using $(subst ...). . $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator for the operating system, and the new $(COMPILER_SEP) the path separator for the compiler tools. . $(BUILD) has been renamed to $(BUILD_DIR). In general, all directory variables end with `_DIR'. The variants ending in `_' (like `BASE_' have been removed). The following ChangeLog entries only describe changes which are not related to the redesign. * builds/beos/beos-def.mk (BUILD_DIR): Fix typo. * builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid overlong arguments as suggested by J. Ali Harlow <ali@avrc.city.ac.uk>. * builds/dos/dos-wat.mk: New file. * builds/freetype.mk (FREETYPE_H): Include header files from the `devel' subdirectory. * builds/os2/os2-dev.mk, builds/unix/unixddef.mk, builds/unix/unixddef.mk, builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk (BUILD_DIR): Fix path. * builds/unix/configure.ac, builds/unic/configure: Updated. * builds/unix/unix-def.in (DISTCLEAN): Add `freetype2.pc'. * devel/ftoption.h: Updated.
