2006-09-30  David Turner  <[e-mail]>

	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec):
	s/unpatented_hinting/ignore_unpatented_hinter/.
	Update all callers.

	* src/base/ftobjs.c (FT_Load_Glyph): Refine the algorithm whether
	auto-hinting shall be used or not.

	* src/truetype/ttobjs.c (tt_face_init): Ditto.

2006-09-30  Werner Lemberg  <[e-mail]>

	* src/base/rules.mk (BASE_SRC): Remove `ftapi.c' (which is no longer
	in use).

	* src/base/ftbase.c: Include `ftlcdfil.c'.

2006-09-29  Werner Lemberg  <[e-mail]>

	* src/sfnt/ttcmap.c (tt_cmap4_char_map_binary): Fix algorithm for
	overlapping segments.  Bug reported by Stefan Koch.

2006-09-28  David Turner  <[e-mail]>

	Fix a bug in the automatic unpatented hinting support which prevents
	normal bytecode hinting to work properly.

	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec):
	s/force_autohint/unpatented_hinting/.  Update all callers.

	* src/base/ftobjs.c (FT_Load_Glyph): Updated code.

	* src/autofit/aftypes.h (AF_DEBUG): Undefine to get rid of traces.

2006-09-27  David Turner  <[e-mail]>

	* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.


	Add a new API to support color filtering of subpixel glyph bitmaps.
	In a default build, the function `FT_Library_SetLcdFilter' returns
	`FT_Err_Unimplemented_Feature'; you need to #define
	FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
	real implementation.

	* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

	* include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
	typedef.
	(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
	`lcd_filter_weights' and `lcd_filter'.

	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
	`hmul' and `vmul'.

	Handle subpixel rendering.
	Simplify function.
	(ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
	(ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.

	* include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
	pointing to <freetype/ftlcdfil.h>.

	* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
	vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.

	* modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.

2006-09-26  David Bustin

	* src/pfr/pfrobjs.c (pfr_face_get_kerning): Skip adjustment bytes
	correctly.  Reported as Savannah bug #17843.

2006-09-26  David Turner  <[e-mail]>

	* src/autofit/afhints.h (AF_HINTS_DO_HORIZONTAL,
	AF_HINTS_DO_VERTICAL, AF_HINTS_DO_ADVANCE): New macros to disable
	horizontal and vertical hinting for the purpose of debugging the
	auto-fitter.

	* src/autofit/afmodule.c (_af_debug_disable_horz_hints,
	_af_debug_disable_vert_hints) [AF_DEBUG]: New global variables.

	* src/autofit/aftypes.h [AF_DEBUG]: Declare above variables.

	* include/freetype/config/ftoption.h, devel/ftoption.h
	(FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
	we want to compile LCD-optimized rendering code (à la ClearType) or
	not.  The macro *must* be disabled in default builds of the library
	for patent reasons.

	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
	LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
	isn't defined at compile time.  This only changes the content of the
	rendered glyph to match the one of normal gray-level rendering,
	hence clients should not need to be modified.

	* docs/CHANGES: Updated.

2006-09-18  Garrick Meeker  <[e-mail]>

	* src/base/ftmac.c (FT_New_Face_From_FOND): Fall back to SFNT if
	LWFN fails and both are available.

2006-09-11  David Turner  <[e-mail]>

	* src/sfnt/sfobjs.c (tt_face_get_name): Support some fonts which
	report their English names through an Apple Roman
	(platform,encoding) pair, with language_id != English.

	If the font uses another name entry with language_id == English, it
	will be selected correctly, though.

	* src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
	selection for `mingli.ttf'.

2006-09-05  Werner Lemberg  <[e-mail]>

	* src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size'
	values which have the upper two bytes set to 0xFF instead of 0x00
	(as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
	`HAN NOM B.ttf').

	* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.

	(gray_record_cell): Simplify.
	(gray_set_cell): Rewrite.
	(gray_start_cell): Apply offsets to `ras.ex' and `ras.ey'.
	(gray_render_span): Don't use FT_MEM_SET for small values.
	(gray_dump_cells) [DEBUG_GRAYS]: New function.
	(gray_sweep): Avoid buffer overwrites when to drawing the end of a
	bitmap scanline.
	(gray_convert_glyph): Fix speed-up.

2006-09-04  David Turner  <[e-mail]>

	* src/smooth/ftgrays.c (gray_convert_glyphs): Make it work with
	64bit processors.

2006-09-01  David Turner  <[e-mail]>

	* src/truetype/ttobjs.c (tt_face_init): Update the TrueType loader
	to recognize a few fonts that require the automatic unpatented
	loader.

	* src/smooth/ftgrays.c: Optmize the performance of the anti-aliased
	rasterizer.  The speed improvement is between 15% and 25%, depending
	on the font data.

	(GRAYS_USE_GAMMA, GRAYS_COMPACT): Removed, and all associated code.
	(TCell): Redefine.
	(TRaster): New members `buffer', `buffer_size', `ycells', `ycount'.
	(gray_init_cells): Updated.
	(gray_find_cell, gray_alloc_cell): New functions.
	(gray_record_cell): Rewritten to use `gray_find_cell' and
	`gray_alloc_cell'.
	(PACK, LESS_THAN, SWAP_CELLS, DEBUG_SORT, QUICK_SORT, SHELL_SORT,
	QSORT_THRESHOLD):
	Removed.
	(gray_shell_sort, gray_quick_sort, gray_check_sort,
	gray_dump_cells): Removed.
	(gray_sweep): Rewritten.
	(gray_convert_glyph): Rewrite code which used one of the sorting
	functions.

	`*/' to avoid `/* in comment' compiler warning.

	* freetype2/src/base/ftdbgmem.c (ft_mem_table_get_source): Turn cast
	`(FT_UInt32)(void*)' into `(FT_UInt32)(FT_PtrDist)(void*)' since on
	64-bit platforms void* is larger than FT_UInt32.

	* freetype2/src/base/ftobjs.c (t_validator_error): Cast away
	volatileness of argument to ft_longjmp.  Spotted by Werner

2006-08-18  Jens Claudius  <[e-mail]>

	* freetype2/src/gxvalid/gxvmod.c (GXV_TABLE_DECL): Mark local

	`ckern', and `valid'.

	2006-08-13.

2006-08-15  suzuki toshiya  <[e-mail]>

	`ft_validator_run' wrapping `setjmp' can cause a crash, as found by
	Jens:
	http://lists.nongnu.org/archive/html/freetype-devel/2006-08/msg00004.htm.

	* freetype2/src/otvalid/otvmod.c: Replace `ft_validator_run' by

	Avoid memory leak if a keyword has been already encountered and its
	value is overwritten.
	* freetype2/src/type1/t1load.c: (t1_keywords): Adjust invocations of
	T1_FIELD_XXX.
	(parse_dict): Ignore keywords that occur in the wrong dictionary

	T1_FIELD_XXX.

	* freetype2/src/type42/t42parse.c: (t42_keywords): Adjust

	Move creation of field `buildchar' of T1_DecoderRec out of
	`t1_decoder_init' and let the caller of `t1_decoder_init' take care
	of it.

	Call the finisher for T1_Decoder in `cid_face_compute_max_advance'
	and `T1_Compute_Max_Advance'.
