2006-11-03  Werner Lemberg  <[e-mail]>

	* src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

2006-11-02  David Turner  <[e-mail]>

	Add a few tweaks to better handle serif fonts.
	Add more debugging messages.

	* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
	segments that are less than 1.5 pixels high.  This gets rid of
	*many* corner cases with serifs.
	(af_latin_align_linked_edge): Add logging message.
	(af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
	Add logging messages.
	Handle AF_EDGE_FLAG flag specially.

	* src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
	_af_debug_disable_blue_hints, and _af_debug_hints variables.

	* src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
	Update external declarations.
	(af_corner_orientation, af_corner_is_flat): Replaced by...

	* include/freetype/internal/ftcalc.h (ft_corner_orientation,
	ft_corner_is_flat): These declarations.

	* src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
	Comment out.  Replaced by...

	* src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
	These functions.  Update all callers.
	(FT_Add64) [!FT_LONG64]: Simplify.

	* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
	(af_direction_compute): Add a missing FT_ABS call.  This bug caused
	production of garbage by missing lots of segments.

2006-10-23  Zhe Su  <[e-mail]>

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
	better deal with broken Asian fonts with strange glyphs, having
	self-intersections and other peculiarities.  The used algorithm is
	based on the nonzero winding rule.

2006-10-23  David Turner  <[e-mail]>

	Speed up the CFF font loader.  With some large CFF fonts,
	FT_Open_Face is now more than three times faster.

	(cff_charset_done): Call `cff_charset_free_cids'.
	(cff_charset_load): Call `cff_charset_compute_cids'.
	(cff_encoding_load) <Populate>: Ditto, to replace inefficient loop.

	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX
	with FT_NEXT_XXX.

	`error' with FT_Err_Ok.

2006-10-14  suzuki toshiya  <[e-mail]>

	* docs/INSTALL.CROSS: New document file for cross-building.

	* builds/unix/configure.raw: Preliminary cross-building support.
	Find native C compiler and pass it by CC_BUILD, and
	find suffix for native executable and pass it by EXEEXT_BUILD.
	Also suffix for target executable is passed by EXEEXT.

	* builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
	build `apinames' which runs on building system.  They are set by
	CC_BUILD and EXEEXT_BUILD.

	normal bytecode hinting to work properly.

	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec):

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.

2006-09-05  David Turner  <[e-mail]>

	(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.

	* 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.
