6a487b59	2005-02-28T22:09:07	* src/base/ftdbgmem.c (FT_DumpMemory): added sorting of memory sources according to decreasing maximum cumulative allocations. * include/freetype/internal/tttypes.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/truetype/ttobjs.c, src/cff/cffobjs.c, src/sfnt/sfobjs.c: implementing new heap-optimized embedded bitmap loader. This one also fixes bug #12107 * src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without a 'kern' table.
e5680279	2005-02-26T00:12:04	* many, many files: several memory optimizations were implemented to drastically reduce the heap usage of FreeType, especially in the case of memory-mapped files. The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e. when it doesn't compromise performance). This had several impacts: first, opening vera.ttf uses a ridiculous amount of memory (when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you'll save at least 20 Kb compared to the non optimized case. performance of various operations, including open/close has also been dramatically improved. More optimisations to come. The auto-hinter eats memory like crazy? This must be stopped...
e70d5531	2005-02-22T16:53:06	* include/freetype/config/ftoption.h, include/freetype/internal/ttypes.h, src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c: added the temporary configuration FT_OPTIMIZE_MEMORY to control various optimizations used to reduce the heap footprint of memory-mapped TrueType files. * src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location, tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table is read directly from memory-mapped streams, instead of being decoded into the heap. * src/truetype/ttpload.c: only load the CVT and fpgm tables when the bytecode interpreter is compiled in.
85cc0a32	2004-11-23T22:10:21	* src/truetype/ttinterp.h: Fix typo.

dea712b4	2004-08-07T15:08:33	`Activate' gray-scale specifing hinting within the TrueType bytecode interpreter.

87c0d30f	2003-12-24T01:10:46	* include/freetype/fttypes.h src/autofit/afangles.c src/autofit/aflatin.c src/autohint/ahglyph.c src/autohint/ahhint.c src/base/ftcalc.c src/base/ftgloadr.c src/base/ftglyph.c src/base/ftobjs.c src/base/ftsynth.c src/base/fttrigon.c src/cff/cffgload.c src/cid/cidgload.c src/cid/cidload.c src/pfr/pfrgload.c src/pfr/pfrload.c src/pfr/pfrsbit.c src/psaux/psobjs.c src/pshinter/pshalgo.c src/pshinter/pshglob.c src/pshinter/pshrec.c src/raster/ftrend1.c src/sfnt/ttcmap0.c src/smooth/ftsmooth.c src/truetype/ttdriver.c src/truetype/ttgload.c src/truetype/ttinterp.c src/truetype/ttobjs.c src/type1/t1gload.c src/winfonts/winfnt.c: use of the FT_PAD_XXX and FT_PIX_XXX macros to avoid compiler warnings with very pedantic compilers. Hints: (x) & -64 will warn if (x) is not signed.. use (x) & ~63 instead !
d90b6738	2003-11-28T22:47:26	Documentation fix.
9f051a7f	2003-11-25T18:15:56	* src/base/ftcalc.c (FT_MulDiv_No_Round): New function (32 and 64 bit version). * include/freetype/internal/ftcalc.h: Updated. * src/truetype/ttinterp.c (TT_MULDIV_NO_ROUND): New macro. (TT_INT64): Removed. (DO_DIV): Use TT_MULDIV_NO_ROUND. * src/pfr/pfrdrivr.c (pfr_get_metrics): Directly use metrics->x_scale and metrics->y_scale.
be67c4ef	2003-11-24T22:54:58	* src/truetype/ttinterp.c (CUR_Func_move_orig): New macro. (Direct_Move_Orig, Direct_Move_Orig_X, Direct_Move_Orig_Y): New functions. Similar to Direct_Move, Direct_Move_X, and Direct_Move_Y but without touching. (Compute_Funcs): Use new functions. (Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45): Fix rounding of value zero. (DO_DIV): Don't use TT_MULDIV.

1c0b8e9d	2003-10-23T04:54:14	Only whitespace changes.
f4c0b921	2003-09-30T05:39:35	* include/freetype/internal/t1types.h: Don't include FT_INTERNAL_OBJECTS_H but FT_INTERNAL_SERVICE_H. * src/truetype/ttobjs.c: Don't include FT_SERVICE_POSTSCRIPT_NAMES_H.
b72d8a85	2003-09-29T20:33:37	* include/freetype/internal/services/svpsname.h (added), include/freetype/internal/psnames.h (removed), include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES): added new service to handle glyph name dictionaries, replacing the old internal header named "psnames.h" by "services/svpsname.h" note that this is different from "services/svpostnm.h" which only handles the retrieval of Postscript font name for a given face. (should we merge these two services into a single header ??) * include/freetype/internal/ftserv.h: adding FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally, instead of only within the current module) * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: adding the new base function ft_module_get_service
17dd0634	2003-09-21T16:04:05	* include/freetype/internal/ftserv.h, include/freetype/internal/service/svpfr.h, include/freetype/internal/pfr.h, src/base/ftpfr.c: migrating the functions of "ftpfr.h" to the new service-base internal API * src/cff/cffobjs.c, src/cid/cidobjs.c, src/pfr/pfrsbit.c, src/psaux/psobjs.c, src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/truetype/ttobjs.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type42/t42objs.c, src/winfonts/winfnt.c: removing various compiler warnings
013efd14	2003-09-17T05:26:33	Formatting.
c313c502	2003-09-11T19:51:54	* include/freetype/ftmm.h, include/freetype/ftmodule.h, include/freetype/tttables.h, include/freetype/config/ftconfig.h, include/freetype/internal/ftobjs.h, include/freetype/internal/ftserv.h, include/freetype/internal/internal.h, include/freetype/internal/sfnt.h, include/freetype/internal/tttypes.h, include/freetype/internal/services/bdf.h, include/freetype/internal/services/glyfdict.h, include/freetype/internal/services/multmast.h, include/freetype/internal/services/postname.h, include/freetype/internal/services/sfnt.h, include/freetype/internal/services/xf86name.h, src/base/ftbdf.c, src/base/ftmm.c, src/base/ftobjs.c, src/base/ftxf86.c, src/bdf/bdfdrivr.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type42/t42drivr.c: heavy internal modifications to introduce the concept of "module services". This is the first step towards a massive simplification of the engine's internals, in order to get rid of various numbers of hacks. Note that this changes will break source & binary compatibility for authors of external font drivers. Maybe 2.1.6 will be called 2.2.0 after all :-)
2bb6ee32	2003-08-18T08:23:40	Some clean-up.
8b6db86b	2003-08-17T22:09:14	* include/freetype/config/ftoption.h, devel/ftoption.h, include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h, src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead, the same effect can be used by setting a debug-hook with FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
43ba0842	2003-06-23T19:26:53	* src/tools/glnames.py: Updated to AGL 2.0. * src/psnames/pstables.h: Regenerated. * include/freetype/cache/ftcglyph.h, include/freetype/ttnameid.h, src/base/ftcalc.c, src/base/fttrigon.c, src/cff/cffgload.c, src/otlayout/otlgsub.c, src/pshinter/pshrec.c, src/psnames/psmodule.c, src/sfnt/sfobjs.c, src/truetype/ttdriver.c: Decorate constants with `U' and `L' if appropriate. * include/freetype/ftmoderr.h: Updated to include recent module additions. * src/pshinter/pshnterr.h (FT_ERR_BASE): Define as `FT_Mod_Err_PShinter'. * src/type42/t42error.h (FT_ERR_BASE): Define as `FT_Mod_Err_Type42'. * src/pshinter/pshrec.h (PS_HINTS_MAGIC): Removed.

779afe4b	2003-06-22T15:33:53	* src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in computation of glyph_index. (FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Size): Assign value to `metrics' after validation of arguments. Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes. The `max_advance' field of the FT_Size_Metrics structure should be used to get the (maximum) width of a strike. * src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single argument to function. * src/psnames/psmodule.c (ps_unicode_value): Handle `.' after `uniXXXX' and `uXXXX[X[X]]'. * src/bdf/bdfdrivr.c: s/FT_Err_/BDF_Err/. * src/cache/ftccache.c, src/cache/ftcsbits.c, src/cache/ftlru.c: s/FT_Err_/FTC_Err_/. * src/cff/cffcmap.c: s/FT_Err_/CFF_Err_/. * src/pcf/pcfdrivr.c: s/FT_Err_/PCF_Err_/. * src/psaux/t1cmap.c: Include psauxerr.h. s/FT_Err_/PSaux_Err_/. * src/pshinter/pshnterr.h: New file. * src/pshinter/rules.mk: Updated. * src/pshinter/pshalgo.c, src/pshinter/pshrec.c: Include pshnterr.h. s/FT_Err_/PSH_Err_/. * src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c: s/FT_Err_/PFR_Err_/. * src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c: s/FT_Err_/SFNT_Err_/. * src/truetype/ttgload.c: s/FT_Err_/TT_Err_/. * src/gzip/ftgzip.c: Load FT_MODULE_ERRORS_H and define FT_ERR_PREFIX and FT_ERR_BASE. s/FT_Err_/Gzip_Err_/.
052904e3	2003-06-17T10:42:27	* include/freetype/ftglyph.h (ft_glyph_bbox_unscaled, ft_glyph_bbox_subpixels, ft_glyph_bbox_gridfit, ft_glyph_bbox_truncate, ft_glyph_bbox_pixels): Replaced with FT_GLYPH_BBOX_UNSCALED, FT_GLYPH_BBOX_SUBPIXELS, FT_GLYPH_BBIX_GRIDFIT, FT_GLYPH_BBOX_TRUNCATE, FT_GLYPH_BBOX_PIXELS. The lowercase variants are now (deprecated aliases) to the uppercase versions.

The lowercase variants are now (deprecated aliases) to the uppercase versions. Updated all other files. * src/base/ftglyph.c (FT_Glyph_Get_CBox): Handle bbox_mode better as enumeration. * src/pcf/pcfdrivr.c (pcf_driver_class), src/winfonts/winfnt.c (winfnt_driver_class), src/bdf/bdfdrivr.c (bdf_driver_class): Add the FT_MODULE_DRIVER_NO_OUTLINES flag.
6ae53a79	2003-06-14T21:39:17	Minor documentation typos.
6e9b3186	2003-06-10T10:54:33	* src/truetype/ttinterp.c (SetSuperRound) <0x30>: Follow Apple's TrueType specification. (Ins_MDRP, Ins_MIRP): Fix single width cut-in test.
0240d29c	2003-06-09T15:54:18	* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Handle Z_STREAM_END correctly. * src/pshinter/pshglob.c (psh_globals_new): Change calculation of dim->stdw.count to avoid compiler problem. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Move the block variables to the beginning of the function to avoid compiler problems. Add casts necessary for 16bit compilers. * src/pfr/rules.mk (PFR_DRV_SRC): Add pfrsbit.c. (PFR_DRV_H): Add pfrtypes.h. * include/freetype/config/ftconfig.h: s/__MWKS__/__MWERKS__/. * src/pfr/pfrsbit.c (pfr_bitwriter_init): Change type of third argument to FT_Bool. (pfr_lookup_bitmap_data): Change type of third and fourth argument to FT_UInt. Updated caller. (pfr_load_bitmap_bits): Change type of fourth argument to FT_Bool.
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.
756655bd	2003-06-07T05:13:22	* src/base/ftmac.c (FT_New_Face_From_SFNT): s/rlen/sfnt_size/ to make it compile. * include/freetype/internal/psaux.h, src/truetype/ttgload.h: s/index/idx/ to fix compiler warnings. * src/sfnt/ttcmap0.c (tt_face_build_cmaps): Use more `volatile' to fix compiler warning. * src/gzip/ftgzip.c (BUILDFIXED): Removed. * src/gzip/inftrees.c (inflate_trees_fixed) [!BUILDFIXED]: Use FT_UNUSED to remove compiler warning.
73861976	2003-06-05T04:31:05	* include/freetype/internal/ftdriver.h, include/freetype/internal/ftobjs.h, include/freetype/internal/psaux.h, src/cid/cidgload.c, src/psaux/psobjs.c, src/psaux/t1decode.c, src/psaux/psobjs.h, src/pshinter/pshrec.c, src/pshinter/pshalgo.c, src/psnames/psmodule.c, src/raster/ftraster.c, src/sfnt/sfobjs.c, src/smooth/ftgrays.c, src/smooth/ftsmooth.c, src/truetype/ttobjs.c, src/truetype/ttdriver.c, src/truetype/ttgload.c, src/type1/t1afm.c, src/type1/t1gload.c, src/type1/t1gload.h, src/type1/t1load.c, src/type1/t1objs.c, src/type42/t42parse.c, src/type42/t42parse.h: Many casts and slight argument type changes to make it work with a 16bit compiler.
6ab56243	2003-06-04T07:59:58	* src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call FT_GlyphLoader_CheckPoints before adding phantom points. This fixes a segfault bug with fonts (e.g. htst3.ttf) which have nested subglyphs more than one level deep. Reported by Anthony Fok. * include/freetype/config/ftoption.h: Define TT_CONFIG_OPTION_BYTECODE_INTERPRETER, TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING, and TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING to make it the new default.
9a8e3211	2003-06-03T15:03:16	* src/truetype/ttinterp.c (Free_Project, CUR_Func_freeProj): Removed. Unused. Updated all callers.
f79a7ae0	2003-05-21T21:47:25	* src/gzip/ftgzip.c (ft_gzip_fil_io): Revert change from yesterday; it has already been fixed differently. * src/truetype/ttinterp.c (DO_SFVTL): Add missing braces around if-clause.
a3f4da8e	2003-04-29T13:23:47	Minor cleanups.
3ea859f6	2003-04-25T11:40:46	Added the unpatented hinting system, which is compiled only if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in ftoption.h
b442ca17	2003-04-23T15:50:27	Cleanups.
1c044d7d	2003-03-15T13:29:49	* src/truetyoe/ttdriver.c (Set_Char_Sizes): fixed a small rounding bug. Actually, it seems that previous versions of FreeType didn't perform TrueType rounding exactly as appropriate.
562731d4	2003-03-14T07:31:35	trying to fix TrueType rendering glitches
b280537b	2003-03-13T21:07:51	* src/base/ftdbgmem.c, docs/DEBUG.TXT: added new environment variables to control memory debugging with FreeType. See the description of "FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX" in DEBUG.TXT * src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c, ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a small memory leak * src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that only happened when trying to resize an array would end in an OOM. * src/smooth/ftgrays.c: removed compiler warnings / volatile bug * src/truetype/ttobjs.c: removed segmentation fault that happened in tight memory environments.
ae26c684	2003-02-25T20:37:50	* src/cache/ftccmap.c: the cmap cache now supports UCS-4 charmaps when available in Asian fonts * src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in comments * src/truetype/ttdriver.c (Set_Char_Sizes): fixed a rounding bug when computing the scale factors for a given character size in points with resolution.
ba4511b8	2003-02-18T22:25:22	* src/truetype/ttdriver.c, src/truetype/ttobjs.h, src/truetype/ttobjs.c, src/truetype/ttinterp.c, src/base/ftobjs.c: fixing the slight distortion problem that occured due to the latest auto-hinter changes
46960df7	2003-02-13T17:49:27	The incremental interface now passes the old metrics when asking for replacement metrics so that they can be modified, not just replaced. For example, CFF fonts need this.
4bdf4350	2003-01-30T23:24:18	various improvements for 2.1.4. see ChangeLog, I've got problems with copy & paste on my desktop !!
14018b4a	2003-01-12T18:26:10	2003-01-11 David Chester <davidchester@qmx.net> * include/freetype/config/ftoption.h, src/autohint/ahglobal.h, src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahtypes.h: included David Chester's patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX macros to control individual "features". Note that all improvements are enabled by default, but can be tweaked for optimization and testing purpose. The configuration macros will most likely disappear in the short future. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h: fixed a structure field definition to avoid memory overwrites
77b68b8e	2003-01-08T09:59:17	* src/truetype/ttgload.c: fixing the TrueType loader to handle invalid composites correctly by limiting the recursion depth
60b32e16	2002-11-06T22:32:54	2002-11-05 David Turner <david@freetype.org> * include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify the use of system-wide zlib. Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore. This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings in optimized mode relative to the "volatile" local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same than a volatile pointer to a variable :-) the fix was to change "volatile FT_Byte* p" into "FT_Byte* volatile p" * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed compiler warnings in optimized modes * src/gzip/.[hc]: modified our ZLib copy in order to prevent exporting any zlib function names outside of the component. This prevents linking problems on some platforms, when applications want to link FreeType _and_ ZLib together. 2002-11-05 Juliusz <jch@pps.jussieu.fr> src/psaux/psobjs.c (ps_table_add): modified increment loop in order to implement exponential behaviour
e59dc91f	2002-09-21T18:43:10	* src/truetype/ttdriver.c (Load_Glyph): Fourth parameter must be FT_Int32. * src/truetype/ttgload.c, src/truetype/ttgload.h (TT_Load_Glyph): Ditto.
25f845aa	2002-09-09T23:45:29	* src/cache/ftccache.i: fixed a bug that prevented compilation in debug mode of template instantiation * src/cff/cffparse.c: fixed the CFF table loader. It didn't accept empty arrays, and this prevented the loading of certain fonts. * src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to prevent seg fault when hints are provided in an empty glyph !! * include/freetype/ftimage.h: removed incorrect "zft_" definitions and updated constants documentation comments * include/freetype/freetype.h (FT_FaceRec): updating documentation comment. The "descender" value is always negative, not positive !
6b5c669b	2002-09-05T15:10:54	* src/cid/cidobjs.c (CID_Size_Init): Renamed to... (cid_size_init): This. * src/psaux/psobjs.c (T1_Builder_Add_Point1): Renamed to... (t1_builder_add_point1): This. Updated all affected code. * src/pshinter/pshalgo3.c (psh3_hint_align): Fix compiler warnings. * src/type1/t1gload.c (T1_Compute_Max_Advance): Ditto. Formatting, minor doc fixes.
b08fe2dc	2002-08-27T20:20:29	* massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
215bf444	2002-08-21T17:36:20	* src/truetype/ttgload.c (TT_Get_Metrics): Add guard for k = 0.

* many, many files: several memory optimizations were implemented to drastically reduce the heap usage of FreeType, especially in the case of memory-mapped files. The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e. when it doesn't compromise performance). This had several impacts: first, opening vera.ttf uses a ridiculous amount of memory (when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you'll save at least 20 Kb compared to the non optimized case. performance of various operations, including open/close has also been dramatically improved. More optimisations to come. The auto-hinter eats memory like crazy? This must be stopped...

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.

2003-01-11 David Chester <davidchester@qmx.net> * include/freetype/config/ftoption.h, src/autohint/ahglobal.h, src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahtypes.h: included David Chester's patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX macros to control individual "features". Note that all improvements are enabled by default, but can be tweaked for optimization and testing purpose. The configuration macros will most likely disappear in the short future. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h: fixed a structure field definition to avoid memory overwrites

2002-11-05 David Turner <david@freetype.org> * include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify the use of system-wide zlib. Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore. This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings in optimized mode relative to the "volatile" local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same than a volatile pointer to a variable :-) the fix was to change "volatile FT_Byte* p" into "FT_Byte* volatile p" * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed compiler warnings in optimized modes * src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting any zlib function names outside of the component. This prevents linking problems on some platforms, when applications want to link FreeType _and_ ZLib together. 2002-11-05 Juliusz <jch@pps.jussieu.fr> * src/psaux/psobjs.c (ps_table_add): modified increment loop in order to implement exponential behaviour

* src/cache/ftccache.i: fixed a bug that prevented compilation in debug mode of template instantiation * src/cff/cffparse.c: fixed the CFF table loader. It didn't accept empty arrays, and this prevented the loading of certain fonts. * src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to prevent seg fault when hints are provided in an empty glyph !! * include/freetype/ftimage.h: removed incorrect "zft_" definitions and updated constants documentation comments * include/freetype/freetype.h (FT_FaceRec): updating documentation comment. The "descender" value is always *negative*, not positive !

* massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.

Modified incremental loading interface to be closer to David Turner's preferences. The header freetype.h is not now affected, the interface is specified via an FT_Parameter, the pointer to the interface is hidden in an internal part of the face record, and all the definitions are in ftincrem.h.

FIX for bug reported by Sven Neumann [sven@gimp.org] on the FreeType development forum: "If FT_CONFIG_OPTION_INCREMENTAL is undefined (this is the default), the TrueType loader crashes in line 852 of src/truetype/ttgload.c when it tries to access face->glyph_locations.".
