David Turner 581ec91c 2003-12-22T21:53:37 * include/freetype/ftcache.h, include/freetype/cache/ftcmanag.h, include/freetype/cache/ftccache.h, include/freetype/cache/ftcmanag.h, include/freetype/cache/ftcmru.h (added), include/freetype/cache/ftlru.h (removed), include/freetype/cache/ftcsbits.h, include/freetype/cache/ftcimage.h, include/freetype/cache/ftcglyph.h, src/cache/ftcmru.c, src/cache/ftcmanag.c, src/cache/ftccache.c, src/cache/ftcglyph.c, src/cache/ftcimage.c, src/cache/ftcsbits.c, src/cache/ftccmap.c, src/cache/ftcbasic.c (added), src/cache/ftclru.c (removed): *Complete* rewrite of the cache sub-system to "solve" the following points: - all public APIs have been moved to FT_CACHE_H, everything under "include/freetype/cache" is only needed by client applications that want to implement their own caches - a new function named FTC_Manager_RemoveFaceID to deal with the uninstallation of FaceIDs - the image and sbit cache are now abstract classes, that can be extended much more easily by client applications - better performance in certain areas. Further optimizations to come shortly anyway... - the FTC_CMapCache_Lookup function has changed its signature, charmaps can now only be retrieved by index - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in private header for the moment)
David Turner 89f331b7 2003-12-21T01:41:32 important bug fixes for new cache code
David Turner 57ecae22 2003-12-19T21:23:58 new version of the cache sub-system - still under debugging
Werner Lemberg 4ee9b7ba 2003-07-02T15:03:36 * src/cache/ftcsbits.c (ftc_sbit_node_compare): Only add `size' if there is no error. Reported by Knut St. Osmundsen <bird-freetype@anduin.net>.
Werner Lemberg 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_/.
Werner Lemberg 7a024104 2003-06-18T06:59:57 * include/freetype/freetype.h (FT_Open_Flags): Replaced with #defines for the constants. (FT_Open_Args): Change type of `flags' to FT_UInt. (FT_GlyphSlot): Move `flags' to FT_Slot_Internal. * include/freetype/ftimage.h (FT_Outline_Flags, FT_Raster_Flag): Replaced with #defines for the constants. * include/freetype/internal/ftobjs.h (FT_Slot_Internal): New field `flags' (from FT_GlyphSlot). Updated all affected source files. (FT_GLYPH_OWN_BITMAP): New macro (from ftgloadr.h). * include/freetype/internal/ftgloadr.h (FT_GLYPH_OWN_BITMAP): Moved to ftobjs.h. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Use dummy FT_GlyphSlot_Internal object.
Werner Lemberg 2acb963b 2003-04-23T06:47:12 Cleanups.
David Turner 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.

Definition of FTC_ImageTypeRec that replaces the obsolete FTC_ImageDesc, and has slightly different fields. The image type is now determined directly by "load_flags" values. * src/autohint/ahtypes.h, src/autohint/ahhint.c, src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements to the automatic and Postscript hinters !! and sub-pixel hinting now works correctly (see demo programs)
Werner Lemberg 8c90c22d 2002-06-08T06:47:18 * src/cache/ftccache.c (ftc_node_hash_unlink, ftc_node_hash_link) [FTC_CACHE_USE_LINEAR_HASHING]: Fix returned error code. Fix debugging messages. * src/type42/t42error.h: New file. * src/type42/t42drivr.c, src/type42/t42objs.c, src/type42/t42parse.c: Use t42 error codes. * src/type42/rules.mk: Updated. * src/base/ftnames.c: Include FT_INTERNAL_STREAM_H.

(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use ft_module_driver_has_hinter conditionally. Moved some type 42 specific structure definitions to... * include/freetype/internal/t42types.h: New file. * include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H): New macro. * include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field `num_grays' for specifying the number of used gray levels. * src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it. Adding a driver for BDF fonts written by Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to better adapt it to FreeType, removing unneeded stuff. Additionally, it now supports Mark Leisher's BDF extension for anti-aliased bitmap glyphs with 2 and 4 bpp. * src/bdf/*: New driver. * include/freetype/internal/bdftypes.h: New file. * include/freetype/internal/fttrace.h: Added BDF driver components. * include/freetype/fterrdef.h: Added error codes for BDF driver. * include/freetype/config/ftmodule.h, src/Jamfile: Updated. * include/freetype/internal/internal.h (FT_INTERNAL_BDF_TYPES_H): New macro. * include/freetype/config/ftstdlib.h (ft_sprintf): New alias for sprintf. * include/freetype/internal/fttrace.h: Added Type 42 driver component. * src/type42/t42drivr.c: Use it. * include/freetype/internal/internal.h (FT_INTERNAL_PCF_TYPES_H): New macro.

(FTC_ImageCache_Lookup): Fix handling of invalid arguments.
David Turner d15bc0d1 2002-04-12T09:31:48 * README.UNX: updated the Unix-specific quick-compilation guide to warn about the GNU Make requirement at compile time.. * include/freetype/config/ftstdlib.h, include/freetype/config/ftconfig.h, include/freetype/config/ftheader.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, src/autohint/ahoptim.c, src/base/ftdbgmem.c, src/base/ftdebug.c, src/base/ftmac.c, src/base/ftobjs.c, src/base/ftsystem.c, src/cache/ftcimage.c, src/cache/ftcsbits.c, src/cff/cffdriver.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cid/cidload.c, src/cid/cidparse.c, src/cid/cidriver.c, src/pcf/pcfdriver.c, src/pcf/pcfread.c, src/psaux/t1cmap.c, src/psaux/t1decode.c, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c, src/pshinter/pshrec.c, src/psnames/psmodule.c, src/raster/ftraster.c, src/sfnt/sfdriver.c, src/sfnt/ttload.c, src/sfnt/ttpost.c, src/smooth/ftgrays.c, src/type1/t1afm.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1load.c, src/type1/t1objs.c, src/type1/t1parse.c: added the new configuration file "ftstdlib.h" used to define aliases for all ISO C library functions used by the engine (e.g. strlen, qsort, setjmp, etc...) this eases the porting of FreeType 2 to exotic environments like XFree86 modules/extensions.. also removed many #include <string.h>, #include <stdlib.h>, etc... from the engine's sources where they're not needed..
Werner Lemberg 48c984b5 2002-03-30T16:41:09 * src/cff/cffdrivr.c (cff_get_glyph_name): Fix debug message. * src/cff/cffobjs.c (CFF_Driver_Init, CFF_Driver_Done) [TT_CONFIG_OPTION_EXTEND_ENGINE]: Removed. * src/cff/sfobjs.c (SFNT_Load_Face) [TT_CONFIG_OPTION_EXTEND_ENGINE]: Ditto. * src/truetype/ttobjs.c (TT_Init_Driver, TT_Done_Driver) [TT_CONFIG_OPTION_EXTEND_ENGINE]: Ditto. * src/truetype/ttdriver.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: Renaming driver functions to the FT_<Subject>_<Action> scheme: TT_Init_Driver => TT_Driver_Init TT_Done_Driver => TT_Driver_Done TT_Init_Face => TT_Face_Init TT_Done_Face => TT_Face_Done TT_Init_Size => TT_Size_Init TT_Done_Size => TT_Size_Done TT_Reset_Size => TT_Size_Reset
David Turner e459d742 2002-03-22T13:52:37 * include/freetype/internal/ftmemory.h, and a lot of other files !!: changed the names of memory macros. Examples: MEM_Set => FT_MEM_SET MEM_Copy => FT_MEM_COPY MEM_Move => FT_MEM_MOVE ALLOC => FT_ALLOC FREE => FT_FREE REALLOC = >FT_REALLOC FT_NEW was introduced to allocate a new object from a _typed_ pointer.. note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer arguments. This results in _lots_ of sources being changed, but makes the code more generic and less error-prone..
David Turner 4a233510 2002-02-24T02:39:08 renaming "ft_glyph_own_bitmap" into "FT_GLYPH_OWN_BITMAP"

David Turner 8edbcabc 2001-06-19T08:28:24 - updated doc for FT_New_Memory_Face - removed lots of compiler warnings in lint-style warning modes (/W4 with Visual C++)
Werner Lemberg 1f7f0e87 2001-06-06T17:30:41 Complete redesign of error codes. Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed. Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets. Its structure is similar to `fterrors.h'. * include/freetype/fterrors.h (FT_NOERRORDEF): New macro. (FT_ERRORDEF): Redefined to use module error offsets. All internal error codes are now public; unused error codes have been removed, some are new. * include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro. All other source files have been updated to use the new error codes; some already existing (internal) error codes local to a module have been renamed to give them the same name as in the base module. All make files have been updated to include the local error files. * src/cid/cidtokens.h: Replaced with... * src/cid/cidtoken.h: This file for 8+3 consistency. * src/raster/ftraster.c: Use macros for header file names.
Werner Lemberg 63408a12 2000-12-13T23:44:37 include/freetype/internal/internal.h: Fixed header inclusion macros to use direct definitions. This is the only way to do these things in a portable way :-( The rest of the code should follow shortly though everything compiles now. * builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files. * builds/win32/detect.mk: Added support for the Intel C/C++ compiler, as well as _preliminary_ (read: doesn't work!) support for Watcom. Also added a new setup target. Type "make setup list" for a list of supported command-line compilers on Win32. * src/base/ftdebug.c: Added dummy symbol to avoid empty file if conditionals are off.
Werner Lemberg cc069beb 2000-12-08T16:17:16 cleanups
David Turner 19ed8afe 2000-12-08T02:42:29 - updated all source files to adhere to the new inclusion scheme - the CFF loader now loads the encodings and charset tables though doesn't use them for now
Werner Lemberg ada9503d 2000-11-29T17:48:57 * src/base/ftcalc.c (FT_SqrtFixed), src/base/ftobjs.c (FT_Set_Renderer): Use FT_EXPORT_DEF. * src/cache/ftcimage.c (FTC_Image_Cache_Lookup), src/cache/ftcmanag.c (FTC_Manager_Done, FTC_Manager_Reset, FTC_Manager_Lookup_Face, FTC_Manager_Lookup_Size, FTC_Manager_Register_Cache), src/cache/ftcsbits.c (FTC_SBit_Cache_Lookup): Ditto. * src/include/freetype/cache/ftcglyph.h (FTC_GlyphNode_Init), src/include/freetype/ftmac.h (FT_New_Face_From_FOND): Use FT_EXPORT.

David Turner 25dee217 2000-11-06T19:29:06 some updates to the cache sub-system. some methods were moved from the concrete "FTC_Image_Cache" and "FTC_SBit_Cache" to the abstract "FTC_Glyph_Cache" and "FTC_Chunk_Cache", respectively.. note: this is not the end of changes to the cache sub-system
David Turner 76a5f623 2000-11-04T01:55:49 major reformatting of the sources: FT_EXPORT_DEF => FT_EXPORT FT_EXPORT_FUNC => FT_EXPORT_DEF BASE_DEF => FT_BASE BASE_FUNC => FT_BASE_DEF LOCAL_DEF => FT_LOCAL LOCAL_FUNC => FT_LOCAL_DEF LOCAL_FUNC_X => FT_CALLBACK_DEF LOCAL_DEF_X => FT_CALLBACK_TABLE FT_CPLUSPLUS => FT_CALLBACK_TABLE_DEF
Werner Lemberg ab855232 2000-10-31T22:13:54 Fixing include header for a `make multi' build. Finishing formatting of cache stuff. Fixed getDriverClass stuff -- added it to winfnt.c also. Note that this still has to be documented.
Werner Lemberg e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
David Turner 29094757 2000-10-31T10:58:23 at last, the infamous cache bug is fixed !!
David Turner ece63798 2000-10-28T23:34:45 completed the sbit cache, though it's still buggy :-( major reformatting of the cache subsystem (again) added substantial documentation too in header files
David Turner 4e4a4363 2000-10-28T13:17:11 - completed the abstract chunk cache class - started implementin a "small-bitmaps" cache derived from it - (soon a "metrics" cache will be written too)
