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.

Werner Lemberg e3b083c6 2008-12-05T22:50:40 * src/autofit/aflatin.c (af_latin_uniranges): Add more ranges. This fixes Savannah bug #21190 which also provides a basic patch.
Werner Lemberg 1a5d561d 2008-11-29T22:50:24 * src/autofit/afcjk.c, src/base/ftoutln.c, src/base/ftrfork.c, src/bdf/bdfdrivr.c, src/gxvalid/gxvmorx.c, src/otvalid/otvmath.c, src/pcf/pcfdrivr.c, src/psnames/pstables.h, src/smooth/ftgrays.c, src/tools/glnames.py, src/truetype/ttinterp.c, src/type1/t1load.c, src/type42/t42objs.c, src/winfonts/winfnt.c: Fix compiler warnings (Atari PureC).

Werner Lemberg e6e6eade 2008-05-14T23:05:38 Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function. (cff_parse_font_matrix): Use it. * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em' FT_ULong. * docs/CHANGES: Document it.

Werner Lemberg 3b0e5006 2007-07-03T04:48:19 * src/autofit/aflatin.c (af_latin_metrics_init_blues): Initialize `round' to pacify compiler. Really commit changes which have been used to build release 2.3.5.
David Turner 74cc0e9e 2007-06-30T22:54:12 * src/truetype/ttinterp.c: add missing variable initialization, gets rid of Valgrind fixes. * src/autofit/aflatin.c: get rid of an infinite loop in the case of degenerate fonts.
Werner Lemberg 7723dc34 2007-06-26T04:44:35 Add autofit module for Indic scripts. This currently just reuses the CJK-specific functions. * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_INDIC): New macro. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. * src/autofit/afindic.c, src/autofit/afindic.h: New files. * src/autofit/afglobal.c, src/autofit/aftypes.h, src/autofit/autofit.c: Updated. * src/autofit/Jamfile (_sources), * src/autofit/rules.mk (AUTOF_DRV_SRC): Updated.
Werner Lemberg 46dde495 2007-06-14T03:59:02 * src/autofit/aflatin.c (af_latin_uniranges): Expand structure to cover all ranges which could possibly be handled by the aflatin module (since the default fallback for unknown ranges is now the afcjk module). It might be necessary to fine-tune this further by splitting off modules for Greek, Cyrillic, or other blocks.

This both speeds up loading the glypn vector themselves and the auto-fitter. note that we've started using inline assembler with GCC to implement FT_MulFix, given that this function is so damn important for the engine's performance. the resulting speed-up is about 25%.

David Turner 2ce92037 2006-03-23T20:58:20 - added FT_Get_SubGlyph_Info API to freetype.h - small fix to lsb/rsb delta computations - cleaning up Jamfile
David Turner 24b9e87b 2006-03-21T16:30:04 * src/autofit/aflatin.c (af_latin_metrics_scale): fixed small bug that crash the auto-hinter (introduce by previous patch). aaah
Werner Lemberg 5a73d8d2 2006-03-20T16:55:32 * builds/freetype.mk (CACHE_DIR, CACHE_H): Remove. (FREETYPE_H): Updated. * src/cache/rules.mk (CACHE_H_DIR): Remove. (CACHE_DRV_H): Updated. Formatting, copyright years.
David Turner e091ce35 2006-03-20T16:01:28 * src/autofit/aflatin.c (af_latin_hints_init): disable horizontal hinting for italic/oblique fonts
David Turner da95af6c 2006-03-20T13:32:33 * builds/win32/visualc/freetype.dsp: updating the project file, adding missing base source files (e.g. ftstroke.c, ftxf86.c, etc...) * src/autofit/afcjk.c, src/autofit/aflatin.c, src/base/ftobjs.c, src/cff/cffobjs.c, src/cid/cidobjs.c, src/pfr/pfrobjs.c, src/sfnt/sfobjs.c, src/sfnt/ttmtx.c, src/truetype/ttpload.c, src/truetype/ttpload.h, src/type1/t1afm.c, src/type1/t1objs.c: removing compiler warnings when building with Visual C++ 6 and /W4
David Turner dad2a2de 2006-03-20T11:48:13 * src/cache/ftccache.h, src/cache/ftcglyph.h, src/cache/ftcimage.h, src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h, src/cache/ftcmru.h: copying the cache's internal header files which were located in 'include/freetype/cache' to the 'src/cache' directory instead. Note that these files are not used by FreeType clients, all cache public APIs have been already moved to include/freetype/ftcache.h, and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it. the move is to allow us to modify the internals without intereference from rogue clients. Note that there are no known client that accesses the cache internals at the moment.
Wu, Chia-I (吳佳一) 2e48a1a1 2006-02-27T09:18:07 * src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics, FT_Load_Glyph): Re-enable glyph metrics grid-fitting. It is now done in the base layer. (FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and height are not too small or too large, just like we were doing in 2.1.10. * src/autofit/afloader.c (af_loader_load_g): The vertical metrics are not scaled.
David Turner 6c71c6b9 2006-02-25T12:49:40 * include/freetype/config/ftoption.h, src/autofit/afcjk.c, src/base/ftobjs.c, src/base/ftutil.c, src/cff/cffobjs.c, src/psaux/afmparse.c, src/sfnt/ttbdf.c, src/tools/apinames.c, src/truetype/ttdriver.c: solved compiler warnings as well as C++ compilation problems

Wu, Chia-I (吳佳一) 4cdb45c0 2006-02-09T14:17:04 Introduce experimental autofit CJK module based on akito's autohint patch. You need to #define AF_MOD_CJK in afcjk.c to enable it. * src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c, src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h: Add CJK module based on akito's autohint patch. * src/autofit/afhints.h (AF_SegmentRec): New field `len' for the overlap length of the segments. (AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros. * src/autofit/aflatin.h (af_latin_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'. Use the character given by the caller. (af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale the thresholds. * src/autofit/afloader.c (af_loader_load_g): Respect AF_SCALER_FLAG_NO_ADVANCE.
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.
David Turner 6a681fa8 2006-01-27T12:11:22 * src/autofit/afwarp.c: simple #ifdef to prevent compilation when the warp hinter isn't active (it shouldn't, still experimental) * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid" and "otvalid" from the list of modules that are linked statically to a given FreeType library. Functionality has been moved to the "ftvalid" CVS module. note also that current Make-based build system still compiles the modules though... * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING, which controls the definitions of the memory management functions to avoid warnings with recent versions of GCC. this macro is only here to be disabled, in case we detect problems with the new scheme. NOTE: disable macro to use the memory debugger. this will be fixed later !!
Werner Lemberg b36bf527 2006-01-22T07:09:54 * src/autofit/afloader.c (af_loader_load_g): Move AF_USE_WARPER up to avoid compiler warnings. * src/autofit/afwarp.c (af_warper_compute_line_best): Remove shadowing variable declarations. Fix warning parameters and replace printf with AF_LOG. (af_warper_compute): Remove unused variable.
Werner Lemberg 1be9ebf5 2006-01-22T06:58:16 * src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c. Formatting, copyright notices, copyright years.
David Turner bb4edc92 2006-01-21T14:31:45 * src/autofit/aflatin.c, src/autofit/afwarp.h, src/autofit/afwarp.c, src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c: adding experimental implementation of "warp hinting" (new hinting algorithm for gray-level and LCD rendering). It is disabled by default, you need to #define AF_USE_WARPER in aftypes.h to enable it.
Werner Lemberg b79b5133 2005-12-20T12:01:58 Formatting, improving comments.
David Turner 5b5f382b 2005-12-14T16:37:15 * src/autofit/aflatin.c, src/autofit/afhints.c: changed the implementation of the LIGHT hinting mode to completely disable horizontal hinting. This is an experimental effort to integrate David Chester's latest patch without fucking the other hinting modes as well. Note that this doesn't force auto-hinting for all fonts however.
