winNT技术操作系统,国外开放的原代码和LIUX一样

	* src/autohint/ahglyph.c (ah_outline_load,
	ah_outline_link_segments): Implement it.
	Fix typos.
	(ah_outline_save, ah_outline_compute_segments): Fix typos.
	* src/autohint/ahhint.c (ah_align_serif_edge): New argument
	`vertical'.  Implement improvement.
	(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.
	Fix typos.
	(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix
	typos.
	(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.
	* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.
	* src/autohint/ahtypes.h: Ditto.
	(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
	(making them global as `ah_debug_disable_horz' and
	`ah_debug_disable_vert').
	Fix typos.

	* tests/gview.c: Updated the debugging glyph viewer to show the
	hints generated by the `autohint' module.

2001-10-27  David Turner  <[e-mail]>

	* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that
	considerably lowered the performance of the abstract chunk cache.

2001-10-26  David Turner  <[e-mail]>

	* include/freetype/ftcache.h, include/freetype/cache/*.h,
	src/cache/*.c: Major re-design of the cache sub-system to provide
	better performance as well as an `Acquire'/`Release' API.  Seems to
	work well here, but probably needs a bit more testing.

2001-10-26  Leonard Rosenthol  <[e-mail]>

	* builds/mac/README: Updated to reflect my taking over the project
	and that is now being actively maintained.

	* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller
	<[e-mail]> to support loading a face other than the
	first from a FOND resource.
	(FT_New_Face_From_FOND): Updated.

2001-10-25  Leonard Rosenthol  <[e-mail]>

	* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac
	OS for latest version (7) of CWPro and for recent changes to the FT
	source tree.

2001-10-25  David Turner  <[e-mail]>

	* include/freetype/config/ftoption.h: Updated comments to explain
	precisely how to use project-specific macro definitions without
	modifying this file manually.

	(FT_CONFIG_FORCE_INT64): Define.

	(FT_DEBUG_MEMORY): New macro.

2001-10-24  Tom Kacvinsky  <[e-mail]>

	* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.

2001-10-23  David Turner  <[e-mail]>

	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
	Improvements to the memory debugger to report more information in
	case of errors.  Also, some allocations that occurred through REALLOC
	couldn't be previously catched correctly.

	* src/autohint/ahglyph.c (ah_outline_compute_segments,
	ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),
	src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced
	liberal uses of memset() by the MEM_Set() macro.

2001-10-23  David Turner  <[e-mail]>

	* src/raster/ftraster.c (Update): Removed to be inlined in ...
	(Sort): Updated.

2001-10-22  David Turner  <[e-mail]>

	* builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory),
	builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),
	builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),
	src/base/ftdbgmem.c: Updated the memory debugger and
	platform-specific implementations of `ftsystem' in order to be able
	to debug memory allocations on Unix, VMS and Amiga too!

	* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed
	some bogus warnings.

	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
	Modified the debugging memory manager to report the location (source
	file name + line number) where leaked memory blocks are allocated in
	the source file.

	* src/base/ftdbgmem.c: New debugging memory manager.  You must
	define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it.  It
	will record every memory block allocated and report simple errors
	like memory leaks and double deletes.

	* src/base/Jamfile: Include ftdbgmem.
	* src/base/rules.mk: Ditto.
	* src/base/ftbase.c: Include ftdbgmem.c.

	* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY
	macro definition.

	* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the
	base component to use the debugging memory manager when the macro
	FT_DEBUG_MEMORY is defined.

2001-10-21  Tom Kacvinsky  <[e-mail]>

	* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
	we are working with a CID keyed CFF font.  Otherwise, a variable
	that was never allocated memory might freed.  This is a correction
	to the previous patch for freeing subfonts.

2001-10-21  Tom Kacvinsky  <[e-mail]>

	* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to
	avoid a memory leak.

2001-10-21  David Turner  <[e-mail]>

	* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,
	src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes
	(in multi-object compilation mode, mainly).

2001-10-20  Tom Kacvinsky  <[e-mail]>

	* src/type1/t1load.c (parse_encoding): Add a test to make sure
	that custom encodings (i.e., neither StandardEncoding nor
	ExpertEncoding) are not loaded twice when the Type 1 font is
	synthetic.

	* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test
	for when loading synthetic fonts to make sure that the font name
	and subrotuines are not loaded twice.  This is to remove a memory
	leak that occurred because the original memory blocks for these
	objects were not deallocated when the objects were parsed the
	second time.

2001-10-19  David Turner  <[e-mail]>

	* src/smooth/ftgrays.c, src/pshinter/pshglob.h,
	src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of
	compiler warnings.

	* src/pshinter/module.mk, src/pshinter/rules.mk: Adding control
	files to build the PostScript hinter with the `old' build system.

2001-10-19  Jacob Jansen  <[e-mail]>

	* descrip.mms, src/pshinter/descrip.mms: Updates to the VMS build
	files.

2001-10-18  David Turner  <[e-mail]>

	* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the
	`glnames.py' script used to generate the `pstables.h' header file.
	The old one contained a serious bug that made FreeType return
	incorrect glyph names for certain glyphs.

	* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of
	pixel size from character size to use rounding.  This is an
	experiment to see whether this gives values similar to Windows for
	scaled ascent/descent/etc.

	* src/base/ftcalc.c (FT_Div64by32): Changed the implementation
	slightly since the original code was mis-compiled on Mac machines
	using the MPW C compiler.

	* src/base/ftobjs.c (FT_Realloc): When a memory block was grown
	through FT_Realloc(), the new bytes were not set to 0, which created
	some strange bugs in the PostScript hinter.
	(destroy_face): Don't deallocate unconditionally.

	* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):
	Adding support to new PostScript hinter.

	* include/freetype/internal/psglobal.h,
	include/freetype/internal/pshints.h,
	include/freetype/config/ftmodule.h, src/pshinter/Jamfile,
	src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h,
	src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.h,
	src/pshinter/pshalgo2.c, src/pshinter/pshglob.h,
	src/pshinter/pshglob.c, src/pshinter/pshinter.c,
	src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c,
	src/pshinter/pshrec.h: Adding new PostScript hinter module.

	* include/freetype/internal/ftobjs.h,
	include/freetype/internal/internal.h,
	include/freetype/internal/psaux.h,
	include/freetype/internal/t1types.h, src/psaux/psobjs.c,
	src/psaux/psobjs.h, src/psaux/t1decode.h, src/psaux/t1decode.c,
	src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,
	src/type1/t1objs.h: Updates to use the new PostScript hinter.

	* tests/Jamfile, tests/gview.c: Adding a new glyph hinting
	viewer/debugger to the source tree.  Note that you will _not_ be
	able to compile it since it depends on an unavailable graphics
	library named `Nirvana' to render vector images.

2001-10-17  David Turner  <[e-mail]>


	* Version 2.0.5 released.

2001-10-08  David Turner  <[e-mail]>

	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.

	* 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.

2001-10-07  Richard Barber  <[e-mail]>

	* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
	correct LRU behaviour.

2001-10-07  David Turner  <[e-mail]>

	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.

2001-10-07  David Turner  <[e-mail]>

	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.

2001-09-15  Detlef Würkner  <[e-mail]>

	* src/type1/t1afm.c (T1_Done_AFM): Free `afm'.

2001-09-10  Yao Zhang  <[e-mail]>

	* src/sfnt/ttcmap.c (code_to_index2): Handle code values with
	hi-byte == 0 correctly.

2001-09-10  Werner Lemberg  <[e-mail]>

2001-08-30  Martin Muskens  <[e-mail]>

	* src/type1/t1load.c (parse_font_matrix): A new way to compute the
	units per EM with greater accuracy (important for embedded T1 fonts
	in PDF documents that were automatically generated from TrueType
	ones).

	* src/type1/t1load.c (is_alpha): Now supports `+' in font names;
	this is used in embedded fonts.

	* src/psaux/psobjs.c (PS_Table_Add): Fixed a reallocation bug that
	generated a dangling pointer reference.

2001-08-30  Anthony Feik  <[e-mail]>

	* src/type1/t1afm.c (T1_Read_Afm): Now correctly sets the flag
	FT_FACE_FLAG_KERNING when appropriate for Type1 + AFM files.

2001-08-25  Werner Lemberg  <[e-mail]>

	* src/sfnt/ttload.c (TT_Load_CMap): Fix frame length of
	`cmap_rec_fields'.

	* include/freetype/fterrors.h [!FT_CONFIG_OPTION_USE_MODULE_ERRORS]:
	Undefine FT_ERR_BASE before defining again.

2001-08-22  Werner Lemberg  <[e-mail]>

2001-08-21  Werner Lemberg  <[e-mail]>

	* builds/dos/dos-def.mk (NO_OUTPUT): Don't use `&>' but `>'.

2001-08-21  David Turner  <[e-mail]>

	* include/freetype/config/ftoption.h: Changed the default setting
	for FT_CONFIG_OPTION_USE_MODULE_ERRORS to undefined, since it breaks
	source compatibility in a few cases.  Updated the comment to explain
	that too.
