2006-06-26  Werner Lemberg  <[e-mail]>

	* src/bdf/bdfdrivr.c (BDF_Face_Init): Handle fonts correctly which
	don't have a POINT_SIZE property.  This fixes Savannah bug #16914.

2006-06-26  Jens Claudius  <[e-mail]>

	(t1_decoder_parse_charstrings): Operator with
	opcode 15 pops its two arguments.

	Improve handling of setcurrentpoint opcode.

2006-06-25  Jens Claudius  <[e-mail]>

	The Type 1 parser now skips over top-level procedures as required
	for a `Simplified Parser'.  This makes the parser more robust as it
	doesn't poke around in PostScript code.  Additionally, it makes the
	FontDirectory hackery in src/type1/t1load.c unnecessary.

	* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
	(skip_literal_string): Add FT_Error as return value.
	Handle escapes better.
	(skip_string): Add FT_Error as return value.
	Don't set `parser->error' but return error code directly.
	(skip_procedure): New function.
	(ps_parser_skip_PS_token): Handle procedures.
	Update code.
	(ps_parser_to_token): Update code.
	(ps_parser_load_field_table): Handle bbox entries also.

	* src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
	Add commented-out code for synthetic fonts.

2006-06-24  Eugeniy Meshcheryakov  <[e-mail]>

	Fix two hinting bugs as reported in
	http://lists.nongnu.org/archive/html/freetype-devel/2006-06/msg00057.html.

	* include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add
	`first_point' member.

	* src/truetype/ttgload.c (tt_prepare_zone): Initialize
	`first_point'.

	* src/truetype/ttinterp.c (Ins_SHC): Fix computation of
	`first_point' and `last_point' in case of composite glyphs.

2006-06-22  suzuki toshiya  <[e-mail]>

	Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
	Mac.  The original patch was written by David Sachitano and Lawrence
	Coopet, and modified by Sean McBride for MPW compatibility.  Only
	required data are converted; unused data are left in big endian.

	* src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
	Mac OS X platforms.
	(OS_INLINE): Undefine before definition.
	(count_faces_sfnt): Insert EndianS16_BtoN to parse the header of
	FontAssociation table in FOND resource.
	(count_faces_scalable): Insert EndianS16_BtoN to parse the header
	and fontSize at each entry of FontAssociation table in FOND
	resource.
	(parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to parse
	ffStylOff of FamilyRecord header of FOND resource, the header,
	fontSize, fontID at each entry of FontAssociation table, and
	StyleMapping table.
	(count_faces): Call `HUnlock' after all FOND utilization.

2006-06-08  suzuki toshiya  <[e-mail]>

	Public API of TrueTypeGX, OpenType, and classic kern table validator
	should return `FT_Err_Unimplemented_Feature' if validation service
	is unavailable (disabled in `modules.cfg').  It is originally
	suggested by David Turner, cf.
	http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

	* src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return
	FT_Err_Unimplemented_Feature if TrueTypeGX validation service is
	unavailable.
	(FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if
	classic kern table validation service is unavailable.

	* src/base/ftotval.c (FT_OpenType_Validate): Return
	FT_Err_Unimplemented_Feature if OpenType validation service is
	unavailable.

2006-06-08  Werner Lemberg  <[e-mail]>

	* src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of
	errors.

2006-06-07  David Turner  <[e-mail]>

	* src/type1/t1afm.c (KERN_INDEX): Make it more robust.
	(T1_Read_Metrics): Fix memory leak which happened when the metrics
	file doesn't have kerning pairs.  This fixes Savannah bug #16768.

2006-06-06  David Turner  <[e-mail]>

	Fix memory leak described in Savannah bug #16759.

	We change `ps_unicodes_init' so that it also takes a
	`free_glyph_name' callback to release the glyph names returned by
	`get_glyph_name'

	* include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
	Renamed to ...
	(PS_GetGlyphNameFunc): This.
	(PS_FreeGlyphNameFunc): New typedef.
	(PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.

	* src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
	argument.
	(cff_sid_free_glyph_name): New function.
	(cff_cmap_unicode_init): Updated.

	* src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated.

	* src/psnames/psmodule.c (ps_unicodes_init): Add variable for
	PS_FreeGlyphNameFunc and use it.


2006-06-04  David Turner  <[e-mail]>

	* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
	`item_size == 0' as well -- though this sounds weird, it can
	theorically happen.  This fixes Savannah bug #16669.

	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
	of `face->num_glyphs' which missed the last glyph, due to
	the offset-by-1 computation, since the PFR format doesn't
	guarantee that glyph index 0 corresponds to the `missing
	glyph.  This fixes Savannah bug #16668.

2006-05-25  Werner Lemberg  <[e-mail]>

	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
	`-no-undefined'.  Reported by Christian Biesinger.

2006-05-19  Brian Weed  <[e-mail]>

	* builds/win32/visualc/freetype.dsp: Release libraries no longer
	have debug information, and debug libraries use `C7 compatible'
	debug info.

2006-05-19  suzuki toshiya  <[e-mail]>

	Apply patch by Derek Clegg to fix two memory leaks in the MacOS
	resource fork handler.  This fixes Savannah bug #16631.

	* src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
	`FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

	* src/base/ftrfrk.c (raccess_guess_linux_double_from_file_name):
	Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

2006-05-19  suzuki toshiya  <[e-mail]>

	dependency, if configured with no options on Mac OS X.

2006-05-19  suzuki toshiya  <[e-mail]>

	* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
	its content cannot be parsed as supported font.  This fixes
	the second part of Savannah bug #16590.

2006-05-18  Werner Lemberg  <[e-mail]>

	* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
	[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

2006-05-17  David Turner  <[e-mail]>

	This is a major patch used to drastically improve the performance of
	loading glyphs.  This both speeds up loading the glyph vectors
	themselves and the auto-fitter module.

	We now use inline assembler code with GCC to implement `FT_MulFix',
	which is probably the most important function related to the
	engine's performance.

	The resulting speed-up is about 25%.


	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
	`cursor' and `limit'.

	* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
	New functions.
	(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
	[TEST]: Remove.

	* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
	code.

	* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
	`FT_ZERO'
	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
	(af_glyph_hints_reload: Rewrite recognition of weak points.

	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
	constant values out of the loops.

	* src/autofit/aftypes.h: Updated.

	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
	product to get orientation.

	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
	(FT_Stream_OpenGzip): Use it to handle small files directly in
	memory.

	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
	Improve performance.

	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
	`limit'.

	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
	exceedingly large values of number of contours.  Speed up by
	reducing the number of loops.

	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.


	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
	used to detect rogue clients from 4 to 16.  This is to prevent some
	segmentation faults with fonts like `KozMinProVI-Regular.otf' which
	comes from the Japanese Adobe Reader Asian Font pack.

2007-05-17  Werner Lemberg  <[e-mail]>

	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
	fixes the first part of Savannah bug #16590.

2006-05-16  Werner Lemberg  <[e-mail]>

	* docs/PROBLEMS: Updated icl issues.

2006-05-12  Werner Lemberg  <[e-mail]>


	* Version 2.2.1 released.

2006-05-10  Werner Lemberg  <[e-mail]>

	directory to suppress generation of .pyc files.  According to the
	Python docs there isn't a more elegant solution (currently).
