奇趣公司比较新的qt/emd版本

2007-01-25  David Turner  <[e-mail]>

	For light auto-hinting, improve glyph advance widths and resurrect
	normal/full hinting to its normal quality.

	* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
	and `xmax_delta'.
	* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
	and `xmax_delta'.

	* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
	preprocessor conditional with if-clause, handling both light and
	normal mode.

	* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
	(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.

2007-01-25  Werner Lemberg  <[e-mail]>

	* docs/release: Updated -- Savannah uses a new uploading scheme.

2007-01-25  David Turner  <[e-mail]>

	* src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.

	* src/cff/cffgload.c (cff_decoder_parse_charstrings)
	<cff_op_callsubr, cff_op_callgsubr>: Fix sanity check for empty
	functions.

	* docs/CHANGES: Document light auto-hinting improvement.

2007-01-25  Werner Lemberg  <[e-mail]>

	* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
	correctly in a sanity check.  Since this function is only used to
	load local and global functions, any charstring that called the last
	local/global function would fail otherwise.  This fixes Savannah bug
	#18867.

	* docs/CHANGES: Document it.

2007-01-23  David Turner  <[e-mail]>

	* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
	prevented compilation when disabling both the unpatented and the
	bytecode interpreter in the TrueType font driver.


	Fix and enable the warper to improve `light' hinting mode.  This is
	not necessarily a final version, but it seems to work well.

	* src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
	Disable code.
	(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
	* src/autofit/aftypes.h: Activate AF_USE_WARPER.

	* src/autofit/afwarp.c (AF_WarpScore): Tune table.
	(af_warper_compute_line_best): Fix array size of `scores'.
	(af_warper_compute): Better handling of border cases.
	* src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
	and `X2'.

2007-01-21  Werner Lemberg  <[e-mail]>

	* ChangeLog: Split off older entries into...
	* ChangeLog.22: This new file.

2007-01-21  Werner Lemberg  <[e-mail]>

	* docs/CHANGES: Document SHZ fix.

2007-01-21  George Williams  <[e-mail]>

	* src/truetype/ttinterp.c (Ins_SHZ): SHZ doesn't move phantom
	points.

2007-01-21  Werner Lemberg  <[e-mail]>

	* src/sfnt/ttmtx.c (tt_face_get_metrics)
	[!FT_CONFIG_OPTION_OLD_INTERNALS]: Fix limit check.

	* src/cff/cffdrvr.c (cff_ps_get_font_info): New function.
	(cff_service_ps_info): Register cff_ps_get_font_info.

2007-01-13  Werner Lemberg  <[e-mail]>

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix compilation
	with C++ compiler.

	* src/autofit/afhints.c (af_glyph_hints_dump_segments,
	af_glyph_hints_dump_edges): Ditto.

2007-01-11  David Turner  <[e-mail]>

	* docs/CHANGES: Small update.

	* src/base/ftobjs.c (IsMacResource): Fix a small bug that caused a
	crash with some Mac OS X .dfont files.  Submitted by Masatake
	Yamato.

	* autogen.sh: Small fix to get it working on Mac OS X properly:
	The issue is that GNU libtool is called `glibtool' on this platform,
	and we must call `glibtoolize', since `libtoolize' doesn't exist.

	* all-sources: Tag all sources with VER-2-3-0-RC1 and
	VER-2-3-0.

	which created an endless loop with some malformed font files.

2007-01-10  Derek Clegg  <[e-mail]>

	* src/type1/t1load.c (T1_Get_MM_Var): Always return fixed point
	values.

2007-01-08  David Turner  <[e-mail]>

	* docs/CHANGES: Updated.

	* include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add
	a new API `FT_Get_Gasp' to return entries of the `gasp' table
	corresponding to a given character pixel size.

	* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
	`gasp' table, in order to avoid potential problems with later
	versions.

	* include/freetype/config/ftheader.h (FT_GASP_H): New macro for
	<freetype/ftgasp.h>.

	* src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),

2007-01-06  Werner Lemberg  <[e-mail]>

	* src/cff/cffload.c (cff_index_init): Remove unused variable.
	(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.

2007-01-04  David Turner  <[e-mail]>

	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
	correctly.  This fixes Savannah bug #17876.


	Do not allocate interpreter-specific tables in memory if we are not
	going to load glyphs with the bytecode interpreter anyway.

	* src/truetype/ttgload.c (tt_loader_init): Load execution context
	only if glyph is hinted.
	Updated.
	* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
	and `cvs_ready'.
	Add `tt_size_ready_bytecode' declaration.
	* src/truetype/ttobjs.c (tt_size_done_bytecode,
	tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
	(tt_size_init): Move most code into `tt_size_init_bytecode'.
	(tt_size_done): Move most code into `tt_size_done_bytecode'.
	(tt_size_reset): Move some code to `tt_size_ready_bytecode'.


	Don't extract the metrics table from the SFNT font file.  Instead,
	reparse it on each glyph load.  The runtime difference is not
	noticeable, and it can save a lot of heap memory when memory-mapped
	files are not used.

	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
	`horz_metrics_offset' and `vert_metrics_ofset'.
	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
	Updated.


	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.


	Do not load the CFF index offsets into memory, since this wastes a
	*lot* of heap memory with large Asian CFF fonts.  There is no
	significant performance loss.

	* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
	* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
	`data_size'.
	(CFF_CharsetRec): Add field `num_glyphs'.

	* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
	cff_charset_cid_to_gindex): New functions.
	(cff_new_index): Renamed to...
	(cff_index_init): This.  Update all callers.
	Updated -- some code has been moved to `cff_index_load_offsets'.
	(cff_done_index): Renamed to...
	(cff_index_done): This.  Update all callers.
	(cff_index_get_pointers, cff_index_access_element): Updated to use
	stream offsets.
	(cff_charset_compute_cids): Set `num_glyphs' field.
	(cff_encoding_load): Updated.

	* src/cff/cffgload.c (cff_slot_load): Updated.

2007-01-04  David Turner  <[e-mail]>

	* docs/INSTALL.UNIX: Simplify some parts, add reference to
	autogen.sh and pointer to README.CVS.

	* README.CVS: Add common problem description and solution
	when running autogen.sh.

	* docs/INSTALL: Add reference to MacOS X.

	* docs/MAKEPP, docs/INSTALL.MAC: New documentation files.

	* docs/TODO: Remove obsolete items.

	* src/raster/ftraster.c: (TRaster_Instance): Replace it with...
	(TWorker): This.
	Remove `count_table' and `memory'.
	Make `grays' a pointer.
	(TRaster): New structure.
	(count_table): New static array.
	(RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
	Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
	ft_black_set_mode, ft_black_render): Updated.
	(ft_black_init): Don't initialize `count_table'.
	(ft_black_reset): Use the render pool.  This saves about 6KB of
	heap space for each FT_Library instance.

	* src/smooth/ftgrays.c (TRaster): Replaced with...
	(TWorker): This.
	Remove `memory'.
	(TRaster): New structure.

	(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
	gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
	gray_render_span, gray_raster_render): Updated.
	(gray_raster_reset): Use the render pool.  This saves about 6KB of
	heap space for each FT_Library instance.

	* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
	FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
	the optimization is no longer experimental.

	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
	Remove a typo that results in no hinting and a memory leak with some
	large Asian CFF fonts.

	* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
	which happens when FT_Done_Library is called with still opened
	CFF_Faces in it.  We need to close all faces before destroying the
	modules, or else some bad things (memory leaks) may happen.

2007-01-02  Werner Lemberg  <[e-mail]>

	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
	Remove compiler warning.
