David Turner 750ddcd5 2001-05-08T12:58:07 * src/pcfdriver.c: fixed incorrect bitmap width computation * docs/docmaker.py: updated the DocMaker script in order to add command line options (--output,--prefix,--title), fix the erroneous line numbers reported during errors and warnings, and other formatting issues.. * src/base/ftcalc.c: various tiny fixes related to rounding in 64-bits routines and pseudo"optimisations" :-)
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 c2cd0044 2001-04-26T00:21:48 minor optimisations in ftcalc.c

Werner Lemberg 29bac136 2001-03-11T11:28:39 * TODO: Updated. * src/cid/cidload.c (parse_font_matrix): Added units_per_EM * src/type1/t1load.c (parse_font_bbox): Changed to use FT_Fixed
Tom Kacvinsky c2f44c16 2001-03-10T19:02:51 Added implementation of three new functions: FT_RoundFix, FT_CeilFix, and FT_FloorFix.
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.
Werner Lemberg 90a03301 2000-11-07T17:21:11 All function comments are now removed from source files (and moved to the header files if necessary). Some minor fixes to have `make multi' run successfully (with gcc and g++). Fixing compiler warnings.
Werner Lemberg 4b68007b 2000-11-07T06:30:29 Complementing David's changes with formatting, adding documentation, etc. More `*'-convention formatting, adding the `a' resp. `an' prefix to variables.
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 e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
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 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 deb4e983 2000-06-29T03:14:25 Formatting... Preprocessor lines now always start the line. Improved error handling in `base' module. Fixed a out-of-bounds error in ttgload.
Werner Lemberg 78575dc0 2000-06-12T19:36:41 A lot of formatting. Added more tracing levels. More Makefile fixes. Minor other changes.
Werner Lemberg 61bd4b9d 2000-06-07T00:00:08 Added FT_FRAME_SKIP_xxx to skip fields. More use of READ_Fields() in ttsbit.c Other minor fixes.
Werner Lemberg 4e6dd858 2000-06-05T05:26:15 freetype.h: Adding ft_encoding_xxx values for some CJK encodings. Fixing copyright notice on many files. Changed some tracing levels. A lot of formatting, fixing documentation etc. as usual.
Werner Lemberg eb81e378 2000-06-03T06:03:11 More preparation for tracing. Formatting.
Werner Lemberg f13e6333 2000-05-30T16:49:14 Formatting; minor improvements.
Werner Lemberg 026bd17b 2000-05-30T05:13:30 ftmulti.c: Will now accept any filename. It will no longer append `.ttf' or `.ttc'. Reformatted. ftcalc.c, ftdebug.c: Minor formatting stuff.
Werner Lemberg c3c344c7 2000-05-29T22:40:57 Fixing the fixes :-) More formatting.
David Turner 4f99c3c4 2000-05-29T20:55:13 fixed divide by zero bug added CFF/OpenType driver source (not working for now)
Werner Lemberg a519b3b7 2000-05-29T20:46:12 Formatting, fixing descriptions.
David Turner 1fb6eea7 2000-05-24T00:31:14 EXPORT_DEF renamed to FT_EXPORT_DEF + reformating/spacing
David Turner 51179f0a 2000-05-18T16:18:05 some fixes for 64-bit systems. Mainly changed some FT_TRACE calls to use %p instead of %lx when dumping a pointer address
David Turner e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
David Turner bfe2f98f 2000-05-12T12:17:15 a new massive grunt work. Redefined the EXPORT_DEF, EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to let them take an argument.. This is needed to compile the library as a DLL on some platforms that have different compiler conventions..
David Turner efce08d6 2000-05-11T18:23:52 major re-organisation of the FreeType 2 directory hierarchy
David Turner 27110613 2000-05-02T10:52:28 added FT_Sqrt64 to ensure that all bytecode operations are strictly equivalent to the ones in FT 1.4 when compiling with the configuration macro FT_CONFIG_OPTION_OLD_CALCS defined..
David Turner e01a41d5 2000-03-28T11:17:58 fixed a stupid bug in FT_MulFix
Werner Lemberg 7880dd66 2000-01-10T17:19:45 ftcalc.c, ftextend.c, ftoutln.c, ftraster.c, ftstream.c: Removing trailing spaces. ftlist.h: Removing duplicated documentation (which is in ftlist.c also). ftinit.c, ftlist.c, ftobjs.c: Formatting, adding documentation.
Werner Lemberg f993b6a0 2000-01-08T17:10:33 demos/config/x11/rules.mk: support for multiple X11R6 entries in $(PATH) added. ftxbbox.c, ftcalc.c, ftdebug.c, ftdriver.h: doc fixes. ftdebug.c: formatting. ftdebug.h: making makros `;'-safe (i.e., they can now be used within if-else clauses without side effects resp. don't produce a single `;').
Werner Lemberg 2b94ffad 2000-01-07T15:02:05 More docs added.
Werner Lemberg 17ae985d 2000-01-02T09:41:30 ftbbox.h: FT_Get_Outline_BBox() must be called FT_Raster_GetBBox(). ftcalc.c: Added a missing closing paranthesis in 64bit version of FT_MulFix(). Some formatting; updating copyright.
