2005-12-13  David Turner  <david@freetype.org>

	Change the implementation of the LIGHT hinting mode to completely
	disable horizontal hinting.  This is an experimental effort to
	integrate David Chester's latest patch without affecting the other
	hinting modes as well.

	Note that this doesn't force auto-hinting for all fonts, however.

	* src/autofit/afhints.c (af_glyph_hints_reload): Don't set
	scaler_fiags here but...
	(af_glyph_hints_rescale): Here.

	* src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal
	hinting for `light' hinting mode.


	* Jamfile: Small fix to ensure that ftexport.sym is placed into the
	same location as other generated objects (i.e., within the `objs'
	directory of the current directory).


	Add support for an embedded `BDF ' table within SFNT-based bitmap
	font files.  This is used to store atoms & properties from the
	original BDF fonts that were used to generate the font file.

	The feature is controlled by TT_CONFIG_OPTION_BDF within
	`ftoption.h' and is used to implement FT_Get_BDF_Property for these
	font files.

	At the moment, this is still experimental, the BDF table format
	isn't cast into stone yet.

	* include/freetype/config/ftoption.h (TT_CONFIG_OPTION_BDF): New
	macro.

	* include/freetype/config/ftstdlib.h (ft_memchr): New macro.

	* include/freetype/internal/tttypes.h (TT_BDFRec, TT_BDF)
	[TT_CONFIG_OPTION_BDF]: New structure.
	(TT_FaceRec) [TT_CONFIG_OPTION_BDF]: New member `bdf'.

	* include/freetype/ttags.h (TTAG_BDF): New macro.

	* src/sfnt/Jamfile (_sources): Add ttbdf.

	* src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttbdf.c.

	* src/sfnt/sfdriver.c [TT_CONFIG_OPTION_BDF]: Include ttbdf.h and
	FT_SERVICE_BDF_H.
	(sfnt_get_charset_it) [TT_CONFIG_OPTION_BDF]: New function.
	(sfnt_service_bdf) [TT_CONFIG_OPTION_BDF]: New service.
	(sfnt_servives) [TT_CONFIG_OPTION_BDF]: Add sfnt_service_bdf.

	* src/sfnt/sfnt.c [TT_CONFIG_OPTION_BDF]: Include ttbdf.c.

	* src/sfnt/sfobjs.c [TT_CONFIG_OPTION_BDF]: Include ttbdf.h.
	(sfnt_done_face) [TT_CONFIG_OPTION_BDF]: Call
	tt_face_free_bdf_props.

	* src/sfnt/ttbdf.h, src/sfnt/ttbdf.c: New files.

2005-12-06  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/truetype/ttobjs.c (tt_size_init): size->ttmetrics.valid is
	initialized twice.
	size->strike_index is not initialized.

2005-12-02  Taek Kwan(TK) Lee  <taeklee@gmail.com>

	* src/type42/t42objs.c (T42_Face_Init): Replace call to

2005-11-29  Chia-I Wu  <b90201047@ntu.edu.tw>

	Major update to distinguish between unsorted and overlapping
	segments for cmap format 4.  For overlapping but sorted segments,
	which is previously considered unsorted, we still use binary search.

	* src/sfnt/ttcmap.h (TT_CMapRec_): Replace `unsorted' by `flags'.
	(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.

	(tt_cmap4_reset): Removed.
	(tt_cmap4_init): Updated accordingly.
	(tt_cmap4_next): Updated accordingly.
	Take care of overlapping segments.
	(tt_cmap4_validate): Make sure the subtable is large enough.
	Do not check glyph_ids because some fonts set the length wrongly.
	Also, when all segments have offset 0, glyph_ids is always invalid.
	It does not cause any problem so far only because the check misses
	equality.
	Distinguish between unsorted and overlapping segments.
	(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions
	to do `charcode => glyph index' by linear/binary search.
	(tt_cmap4_char_index, tt_cmap4_char_next): Use
	tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
	(tt_face_build_cmaps): Treat the return value of validator as flags
	for cmap.

2005-11-29  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/sfnt/ttcmap.c (TT_CMap12Rec_, tt_cmap12_init, tt_cmap12_next):
	New structures and functions for fast `next char'.
	(tt_cmap12_char_map_binary): New function to do `charcode => glyph
	index' by binary search.
	(tt_cmap12_char_index, tt_cmap12_char_next): Use
	tt_cmap12_char_map_binary.
	(tt_face_build_cmaps): Check table and offset correctly (equality is
	missing).

	* builds/amiga/smakefile: Adjusted the compiler options
	to the current sources, now really builds the gxvalid, gzip
	and psnames modules.

	* builds/amiga/src/base/ftsystem.c: The assumed Seek() position
	in the file cache was off by one byte which could cause false
	errors in font files.

	* src/sfnt/ttload.c (sfnt_dir_check): Clean up and return correct

	* docs/CHANGES: Mention SING Glyphlet support.

2005-09-22  David Turner  <david@freetype.org>

	* src/base/Jamfile: Disable compilation of ftgxval module
	temporarily.

2005-09-19  David Somers  <dsomers@omz13.com>

	* freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
	font to have no `head' table if tables `SING' and `META' are
	present; this is to support `SING Glyphlet'.

	`SING Glyphlet' is an extension to OpenType developed by Adobe
	primarily to facilitate adding supplemental glyphs to an OpenType
	font (with emphasis on, but not necessariy limited to, gaiji to a
	CJK font).  A SING Glyphlet Font is an OpenType font that contains
	the outline(s), either in a `glyf' or `CFF' table, for a glyph;
	`cmap', `BASE', and `GSUB' tables are present with the same format
	and functionaliy as a regular OpenType font; there are no `name',
	`head', `OS/2', and `post' tables; there are two new tables, `SING'
	which contains details about the glyphlet, and `META' which contains
	metadata.

	Further information on the SING Glyphlet format can be found at:

	  http://www.adobe.com/products/indesign/sing_gaiji.html

	* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
	macros for the OpenType tables `SING' and `META'.  These two tables
	are used in SING Glyphlet Format fonts.

	glyph slot initialization.
	(Load_Glyph): Load flag dependencies are handled here.  Return error

	TT_Vary_Get_Glyph_Deltas now.
	(TT_LOADER_SET_PP): New macro to calculate and set the four phantom
	points.
	(load_truetype_glyph): Never set exec->glyphSize to 0.  This closes
	Savannah bug #13107.
	Forget glyph frame before calling TT_Process_Simple_Glyph.
	Use TT_LOADER_SET_PP.
	Scale all four phantom points.
	Split off some functionality to ...
	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
	new functions.
	(TT_Load_Glyph): Set various fields of `glyph' here, not in
	load_truetype_glyph and compute_glyph_metrics.
	Split off some functionality to ...
	(load_sbit_image, tt_loader_init): These new functions.

	which won't be fixed in the very near future).

	* Jamfile (FT2_COMPONENTS): Include otvalid (again).

	* src/otvalid/otvcommn.h (OTV_NAME, OTV_FUNC): New macros.
	(OTV_NEST1, OTV_NEST2, OTV_NEST3): Use OTV_NAME and OTV_FUNC to

2005-06-16  Werner Lemberg  <wl@gnu.org>

	* include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.
	(FREETYPE_PATCH): Set to 0.
