qt专门用于嵌入式的图形开发GUI

2004-06-23  Werner Lemberg  <[e-mail]>

	* include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare
	FT_QAlloc_Debug and FT_QRealloc_Debug.

	* src/base/ftutil.c (FT_QAlloc): Fix error and debug messages.
	(FT_QRealloc): Call FT_QAlloc if original pointer is NULL.
	Fix error message.

2004-06-23  David Turner  <[e-mail]>

	* include/freetype/internal/ftmemory.h, src/base/ftutil.c
	(FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,
	FT_QRealloc_Debug): New functions that perform allocation without
	zero-ing out the corresponding blocks.

	* include/freetype/internal/ftmemory.h (FT_MEM_QALLOC,
	FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY,
	FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY,
	FT_QRENEW_ARRAY): New macros.

	* src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC.
	* src/gzip/ftgzip.c (FT_Stream_OpenGzip):  Use FT_QNEW_ARRAY.
	* src/sfnt/sfobjs.c (tt_face_get_name): Use FT_QNEW_ARRAY.

	* src/sfnt/ttload.c (tt_face_load_directory, tt_face_load_metrics,
	tt_face_load_gasp): Use FT_QNEW_ARRAY.
	(tt_face_load_kern): Use FT_QNEW_ARRAY.
	Small optimization in the kerning table verifier; this speeds up
	TrueType face opening by about 7%.
	(tt_face_load_hdmx): Use FT_QNEW_ARRAY and FT_QALLOC.

	* include/freetype/config/ftmodule.h: Changed the order of modules,
	putting TrueType and Type 1 first.  This dramatically improves the
	performance of face open/close operations.  For example, putting the
	TrueType driver first in the list results in a 5x speedup when
	opening `Vera.ttf'.

	The very problem is that both the PCF and BDF drivers do a lot more
	than necessary to detect that they cannot handle a font file.

2004-06-22  Werner Lemberg  <[e-mail]>

	* src/pcf/pcfread.c (pcf_read_TOC, pcf_get_properties,
	pcf_get_metrics, pcf_get_bitmaps, pcf_get_encodings): Improve
	debugging messages.

	* src/pcf/pcfdrivr.c (FT_COMPOMENT): Move up.
	(PCF_Face_Init): Simplify code.

	* src/bdf/bdfdrivr.h (BDF_FaceRec): New element `default_glyph'.

	* src/bdf/bdflib.c (_bdf_add_property, _bdf_parse_start),
	src/bdf/bdf.h (bdf_font_t): s/default_glyph/default_char/.

	* src/bdf/bdfdrivr.c (BDF_Face_Init): Fix number of glyphs.
	Set `default_glyph'.
	(BDF_Glyph_Load): Use `default_glyph' for undefined glyph.

	* docs/CHANGES: Updated.

	* docs/CHANGES: Updated.

2004-06-21  David Turner  <[e-mail]>

	* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
	load_truetype_glyph): Don't access (unrounded)
	`TT_Size.root.metrics' but (rounded) `TT_Size.metrics'.  This fixes

	interpreter was enabled.

2004-06-14  Huw D M Davies  <[e-mail]>

	FreeType versions.

	ftc_size_node_compare_faceid, ftc_face_node_compare): Change return
	type to FT_Bool.

	* src/cache/ftcsbits.c (FTC_SNode_Free, ftc_snode_free): Make the
	former call the latter, not vice versa.

2004-06-04  Werner Lemberg  <[e-mail]>

2004-06-04  David Chester  <[e-mail]>

	`lsb_delta' and `rsb_delta'.

	`rsb_delta' in slot->metrics and tune side bearings slightly.

2004-06-04  David Turner  <[e-mail]>

	* src/autofit/*: Important fixes to the auto-fitter.  The output
	now seems to be 100% equivalent to the auto-hinter, while being
	about 2% faster (which proves that script-specific algorithm
	selection isn't a performance problem).

	To test it, change `autohint' to `autofit' in
	<freetype/config/ftmodule.h> and recompile.

	A few more testing is needed before making this the official
	auto-hinting module.

	Use mm_axis_unmap and mm_weights_unmap to provide default values
	for design and normalized axis coordinates.
