Werner Lemberg 94ffae52 2002-04-14T00:54:32 * src/cff/cffgload.c (CFF_Parse_CharStrings): s/rand/Rand/ to avoid compiler warning. formatting/fixing ChangeLog
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..
David Turner 2c7558ce 2002-04-11T14:21:16 * README, docs/CHANGES, Jamfile.in: updating for the 2.1.0 release
Werner Lemberg 91db04cb 2002-04-01T14:25:28 * src/truetype/ttgload.c: 16bit fixes. (TT_Load_Simple_Glyph): Improve debug messages. (load_truetype_glyph): Remove dead code. * src/truetype/ttinterp.c: 16bit fixes. * src/truetype/ttobjs.c: Ditto. * include/freetype/ftsnames.h, include/freetype/internal/sfnt.h, src/cff/cffload.h, src/psaux/psobjs.h, src/truetype/ttinterp.[ch], src/sfnt/ttpost.h: s/index/idx/. formatting, copyright updates.
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 222cec8c 2002-02-21T11:48:48 * include/freetype/internal/ftdebug.h, src/base/ftdebug.c: modified the debug sub-system initialization. trace levels can now be specified within the "FT2_DEBUG" environment variable. See the comments within "ftdebug.c" for more details * include/freetype/internal/fttrace.h: new file to define the trace levels used for debugging. it is used both to define enums and toggle names for FT2_DEBUG * src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to FT_ASSERT * include/freetype/internal/ftextend.h, src/base/ftextend.c, src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the library, since it is now completely obsolete..
Werner Lemberg e274290d 2002-01-28T05:04:22 * src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused bad rendering of thin lines (less than one pixel thick).
Werner Lemberg 3975e2e1 2002-01-09T21:01:18 Formatting.
David Turner db3ac3b3 2002-01-09T10:48:25 small speed-up to the anti-aliased renderer
Werner Lemberg c3b21608 2001-12-05T01:22:05 Formatting. Cleaning up of ChangeLog. * docs/license.txt: s/X Windows/X Window System/. * src/raster/ftraster.c: Fix definition condition of MEM_Set(). * src/smooth/ftgrays.c (M_Y): Change value to 192. * src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter. Remove unused variable. * src/cache/ftcimage.c (ftc_image_node_init, ftc_image_node_compare): Remove unused variables. * src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused variable. * src/raster/ftraster.c (MEM_Set): Move definition down to avoid compiler warning. * src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to avoid compiler warnings. * src/pcf/pcfread.c (tableNames): Use `const'. (pcf_read_TOC): Change counter name to avoid compiler warning. Use `const'. * src/pshinter/pshrec.c (ps_hints_close): Remove redundant declaration. * src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables to avoid shadowing. * src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto. * src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()' and `T1_Size_Done()'.
David Turner f2c56515 2001-11-20T01:29:34 * src/pshinter/{pshalgo2.c, pshalgo1.c}: fixed stupid bug in sorting routine that created nasty alignment artefacts. * src/pshinter/pshrec.c, tests/gview.c: debugging updates.. * src/smooth/ftgrays.c: de-activated experimental gamme support, apparently, "optimal" gamma tables depend on the monitor type, resolution and general karma, so it's better to compute them outside of the rasterizer itself..
David Turner adf07a93 2001-10-30T23:51:24 * src/smooth/ftgrays.c: adding experimental "gamma" support. This produces smoother glyphs at small sizes for very little cost * src/autohint/ahglyph.c, src/autohint/ahhint.c: various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters) * tests/gview.c: updated the debugging glyph viewer to show the hints generated by the "autohint" module
David Turner 5a1de37e 2001-10-24T07:32:55 replaced liberal uses of "memset" by the "MEM_Set" macro call (some platforms don't provide this ANSI function !!) some changes to "ftsystem.c" implementations in order to use the new memory debugger on Unix, VMS and Amiga too !!
David Turner 7e4b52d1 2001-10-19T09:17:49 getting rid of compiler warnings
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)..

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
