Werner Lemberg 80b8d770 2001-10-10T19:56:42 Fixed a bug in `glnames.py' that prevented it from generating correct glyph names tables. This resulted in the unavailability of certain glyphs like `Cacute', `cacute' and `lslash' in Unicode charmaps, even if these were present in the font (causing problems for Polish users). * src/tools/glnames.py (mac_standard_names): Fixed. (t1_standard_strings): Some fixes and renamed to ... (sid_standard_names): This. (t1_expert_encoding): Fixed. (the_adobe_glyph_list): Renamed to ... (adobe_glyph_names): This. (the_adobe_glyphs): Renamed to ... (adobe_glyph_values): This. (dump_mac_indices, dump_glyph_list, dump_unicode_values, main): Updated. * src/psnames/pstables.h: Regenerated. * src/psnames/psmodule.c (PS_Unicode_Value): Fix offset. Fix return value. Use `sid_standard_table' and `ps_names_to_unicode' instead of `t1_standard_glyphs' and `names_to_unicode'. (PS_Macintosh_Name): Use `ps_glyph_names' instead of `standard_glyph_names'. (PS_Standard_Strings): Use `sid_standard_names' instead of `t1_standard_glyphs'. * doc/BUGS, doc/TODO: New documents. * src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented correct LRU behaviour. setjmp() and longjmp() are now used for rollback (i.e. when memory pool overflow occurs). Function names are now all uniformly prefixed with `gray_'. * src/smooth/ftgrays.c: Include <setjmp.h>. (ErrRaster_MemoryOverflow): New macro. (TArea): New type to store area values in each cell (using `int' was too small on 16-bit systems). <limits.h> is included to properly get the needed data type. (TCell, TRaster): Use it. (TRaster): New element `jump_buffer'. (gray_compute_cbox): Use `RAS_ARG' as the only parameter and get `outline' from it. (gray_record_cell): Use longjmp(). (gray_set_cell): Use gray_record_cell() for error handling. (gray_render_line, gray_render_conic, gray_render_cubic): Simplify. (gray_convert_glyph_inner): New function, using setjmp(). (gray_convert_glyph): Use it. Provide a public API to manage multiple size objects for a given FT_Face in the new header file `ftsizes.h'. * include/freetype/ftsizes.h: New header file, * include/freetype/internal/ftobjs.h: Use it. Remove declarations of FT_New_Size and FT_Done_Size (moved to ftsizes.h). * include/freetype/config/ftheader.h (FT_SIZES_H): New macro. * src/base/ftobjs.c (FT_Activate_Size): New function. * src/cache/ftcmanag.c: Include ftsizes.h. (ftc_manager_init_size, ftc_manager_flush_size): Use FT_Activate_Size.
David Turner c4f622c3 2001-10-07T10:39:03 * src/smooth/ftgrays: "setjmp/longjmp" is now used for rollback (i.e. when memory pool overflow occurs), function names are now all prefixed with "gray_", and a new type (TArea) is defined to store area value in each cell (using "int" was too small on 16-bit systems)..

Werner Lemberg 8eb0353f 2001-06-19T23:03:41 Formatting.
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 cf24d515 2001-06-18T14:23:45 Minor cleanups to remove compiler warnings. * include/freetype/cache/ftcmanag.h (FTC_MAX_BYTES_DEFAULT): Use `L' for constant. * include/freetype/config/ftoption.h (FT_RENDER_POOL_SIZE): Ditto. * src/base/ftcalc.c (FT_MulDiv): Use `L' for constant. * src/base/ftglyph.c (FT_Glyph_Get_CBox): Remove `error' variable. * src/base/fttrigon.c (ft_trig_arctan_table): Use `L' for constants. * src/base/ftobjs.c (FT_Done_Size): Fix return value.

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 3780273e 2001-04-26T13:34:36 * builds/unix/config.guess, builds/unix/config.sub: Updated to latest versions from gnu.org. * builds/compiler/gcc-dev.mk: Add `-Wno-long-long' flag. * include/freetype/internal/ftcalc.h: Define FT_SqrtFixed() uncoditionally. * src/base/ftbbox.c: Include FT_INTERNAL_CALC_H. Fix compiler warnings. * src/base/ftcalc.c: Fix (potential) compiler warnings. * src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit fixed-point square root computation. It is now used even with 64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-) * src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line. * src/base/ftbbox.c (BBox_Cubic_Check): Rewrote function to use direct computations with 16.16 values instead of sub-divisions. It is now slower, but proves a point :-) * src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c: Fixed the bezier stack depths. * src/base/ftcalc.c (FT_MulFix): Minor rounding fix. * builds/beos: Added BeOS-specific files to the old build system (no changes were necessary to support BeOS in the Jamfile though). * ftconfig.h, ftoption.h: Updated "ftconfig.h" to detect 64-bit int types on platforms where Autoconf is not available). Also removed FTCALC_USE_LONG_LONG and replaced it with FT_CONFIG_OPTION_FORCE_INT64. * builds/win32/freetype.dsp: Updated the Visual C++ project file. Doesn't create a DLL yet. * cffgload.c: Removed a compilation warning.
David Turner caf72cd6 2001-04-25T18:11:16 * src/base/ftbbox.c (BBox_Cubic_Check): rewrote function to use direct computations with 16.16 values instead of sub-divisions. It is now slower, but proves a point :-) * src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c : fixed the bezier stack depths.. * src/base/ftcalc.c (FT_MulFix): minor rounding fix * builds/beos : added BeOS-specific files to the old build system (no changes were necessary to support BeOS in the Jamfile though)
David Turner 8d3a401f 2001-03-20T11:14:24 * builds/*/*-def.mk: changed the objects directory from "obj" to "objs" * include/freetype/config/ftheader.h: removed obsolete macros like FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that were previously defined in <freetype/ftcache.h>. Added comments to be included in a new API Reference section. * src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component needs to added its own directory to the include path at compile time. Modified all "rules.mk" and "descrip.mms" accordingly..
Werner Lemberg 914b289f 2001-03-10T17:07:42 * src/*/*.c: Added many casts to make code more 64bit-safe.
David Turner 5aeaad6c 2001-02-23T17:47:41 fixed a bug reported by Graham Asher
Werner Lemberg 594f0c96 2000-12-20T22:09:41 * *.mk: Added lots of `.PHONY' targets. * *.mk: Implemented `platform' target to disable auto-detection. Added support for clipped direct rendering in the smooth renderer. This should not break binary compatibility of existing applications. * include/freetype/fttypes.h, include/freetype/ftimage.h: Move definition of the FT_BBox structure from the former to the latter. * include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to FT_Raster_Flag enumeration. Add `clip_box' element to FT_Raster_Params structure. * src/smooth/ftgrays.c (grays_convert_glyph): Implement it. * src/raster/ftraster.c (ft_black_render): Test for unsupported direct rendering before testing arguments.
David Turner 859a18a3 2000-12-14T18:50:40 support for clipped direct rendering updated INSTALL file for Win32 case
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.
David Turner 170c0d4c 2000-12-13T19:55:11 * include/freetype/config/ft2build.h, 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, 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..
Werner Lemberg d5c1b27d 2000-12-12T22:28:12 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT): Removed. ANSI C doesn't (explicitly) allow macro expansion in arguments using `##'. (FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory names directly. Make them configurable. Use `##' to strip leading and trailing spaces from arguments. * builds/unix/ft2unix.h: Adapted. * src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream, ft_close_stream): Use FT_CALLBACK_DEF. * builds/unix/ftsystem.c: Use new header scheme. (FT_Done_Memory): Use free() from FT_Memory structure. * src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes. * include/freetype/config/ft2build.h (FT2_CONFIG_ROOT, FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE, FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.
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
David Turner dc26e7b7 2000-10-23T22:46:56 - minor reformatting of "ftmodule.h" - added missing "const" statements in the source code in order to really get rid of writable static variables
Werner Lemberg 6fbe4db6 2000-10-05T04:53:31 minor formatting issues
David Turner ec0b2cd9 2000-10-03T19:22:52 small fix: when in direct rendering mode, the target bitmap buffer is not checked..
David Turner 78dd7104 2000-10-03T19:13:11 small fix: when in direct rendering mode, the target bitmap buffer is not checked..
David Turner b71c6af0 2000-09-17T17:17:16 fixed minor bug in the smooth renderer which forced the span callback to be called with y == -1 and count == 0
Werner Lemberg f9b03750 2000-09-11T22:50:13 small formatting issues.
David Turner a8194a97 2000-09-02T00:20:42 - added a new function called FT_SqrtFixed to compute the 16.16 square root of a 16.16 number (this could come handy in a later version of the auto-hinter) - small fixes to the smooth renderer. It used to use way too much line segments when drawing beziers !!
Werner Lemberg b48a6094 2000-07-09T19:15:30 Formatting. Moving some internal structures and constants from freetype.h to ftobjs.h. Finally removing FT_LOAD_ANTI_ALIAS. Cleaning up all error codes. Only the used ones have survived :-) Removed unused FT_MAX_GLYPH_FORMATS constant. T2 error codes are now in the range 0x500-0x5FF (instead of `TrueDoc'). Some minor improvements of error return values. Finally fixing error code values in ftraster and ftgrays to be compliant with all other FT error codes.
Werner Lemberg 7fa51b55 2000-07-08T19:51:42 Formatting. Adding some trivial error checking. Adding/Fixing tracing levels.
David Turner a90663f5 2000-07-08T00:41:13 vast clean-up of the sources in order to allow flat directory compilation (by defining the FT_FLAT_COMPILE macro at compile time..) moved "freetype2/BUILD" to "freetype2/docs/BUILD"
Werner Lemberg bd5ae400 2000-07-05T04:32:02 Run g++ on the FreeType library. This should make the use of code in C++ programs easier: Renamed FT_WordXX to FT_UIntXX. Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType always accesses streams byte-wise, so this makes sense IMHO. Added a lot of #ifdef __cplusplus to header files (and removed a few). Other minor syntax fixes (mostly casts). Replaced the variable `private' with `private_dict' -- `private' is reserved in C++.
David Turner c6a92202 2000-07-04T18:12:13 various clean-ups: - using FT_UNUSED instead of UNUSED - using FT_LONG64 and FT_INT64 instead of LONG64 & INT64 - using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of... - removed the #ifdefs that used SIZEOF_INT, instead we now use FT_Int32 and FT_UInt32 when needed to support 32-bits quantity correctly on 64-bits systems..
Werner Lemberg fbeb41d9 2000-07-02T00:27:53 Formatting. Adding copyright notices. Removing an unnecessary file (smooth.h).
David Turner f9ca2bb5 2000-06-30T23:12:55 managed to re-design entirely the API in <freetype/ftglyph.h> It is now really the "glyph factory" that Stefan was probably dreaming about.. fixed some recent formatting errors from Werner ;-) cleaned up the demonstration programs from most of the rust that they had, though I'm sure someone is going to re-format them really soon !! "ftstring" now uses the new ftglyph.h API, and is now faster and smaller.. yep..
David Turner 5ae1bad3 2000-06-27T23:18:39 added new renderer module
