2006-01-27  David Turner  <david@freetype.org>

    * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
    the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.
    
    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.
    
    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

    * builds/win32/visualc/freetype.dsp: updating project file to
    define FT2_BUILD_LIBRARY, and remove gxvalid+otvalid from
    compilation

    * builds/freetype.mk, Jamfile: define the macro FT2_BUILD_LIBRARY
    when compiling the library.
    
    * include/freetype/config/ftheader.h: remove inclusions of
    internal headers, except if the macro FT2_BUILD_LIBRARY is defined.
    

2006-01-23  Chia-I Wu  <b90201047@ntu.edu.tw>

	* include/freetype/freetype.h (FT_Select_Size): Rename the second
	argument from `idx' to `strike_index'.
	(FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
	this enum.

	* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,
	FT_REQUEST_HEIGHT): New macros to get the width and height of a
	request, in fractional pixels.

	* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
	FT_Request_Metrics): New base functions to set the font metrics.  They
	were part of FT_Select_Size/FT_Request_Size and are made independent
	functions so that metrics are not set again and again.

	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
	only when driver's size_select/size_request is NULL.  That is, drivers
	should set the metrics themselves.
	(FT_Match_Size): Round before matching.  This was what we did and it
	does cause some problems without rounding.

	* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
	(tt_size_select): Set the font metrics.
	s/index/strike_index/.
	The scaled metrics are always preferred over strikes' metrics, even
	when some strike is selected.  This is done because the strikes'
	metrics are not reliable, e.g., the sign of the descender is wrong for
	some fonts.

	* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
	(tt_size_request): Set the font metrics.
	Call cff_size_select/tt_size_select when some strike is matched.

	* src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c,
	src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c,
	src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
	Set the font metrics.
	s/index/strike_index/.

	* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
	files were committed.  Just a catch-up.
	(PS_Conv_ToFixed): Remove the `goto'.
	(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.

	* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
	tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
	(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
	advertised metrics in `available_sizes' are different from those
	actually used.

2006-01-23  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/psaux/psaux.c src/psaux/psauxmod.c src/type1/t1driver.c: Make

	`texinfo' CVS module at savannah.gnu.org.

2006-01-21  Werner Lemberg  <wl@gnu.org>

	* src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c.

	* src/autofit/afloader.c (af_loader_load_g): Move AF_USE_WARPER up
	to avoid compiler warnings.

	* src/autofit/afwarp.c (af_warper_compute_line_best): Remove
	shadowing variable declarations.
	Fix warning parameters and replace printf with AF_LOG.
	(af_warper_compute): Remove unused variable.

2006-01-20  David Turner  <david@freetype.org>

	Adding experimental implementation of `warp hinting' (new hinting
	algorithm for gray-level and LCD rendering).  It is disabled by
	default, you need to #define AF_USE_WARPER in aftypes.h.

	* src/autofit/afhints.c (af_glyph_hints_scale_dim) [AF_USE_WARPER]:
	New function.

	some modifications, from the file psobjs.c.

	* src/psaux/psobjs.c: Use functions from psconv.c.

	* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Add
	`AFM_Parser' to the `psaux' service.

	`Kerning' service.  It is currently only used to get the track
	kerning information.

	* include/freetype/internal/ftserv.h (FT_SERVICE_KERNING_H): New
	macro.

	* src/type1/t1driver.c, src/type1/t1objs.c, src/type1/t1afm.c,

	which are monotone.

	* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
	formattings in vertical metrics faking.  There is still room for

	clarifications.
	The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
	change need be made to the code.

	* src/base/ftobjs.c (FT_Load_Glyph): Resolve flag dependencies and
	decide whether to use the auto-hinter according to documentation.
	There should to be no real difference.
	Some checks (e.g., is text height positve?) after the glyph is
	loaded.
	(FT_Select_Size, FT_Request_Size): Scales are set to wrong values.

	matching for requests of type NOMINAL and REAL_DIM.

	* src/winfonts/winfnt.c (FNT_Face_Init): Print trace message when
	`pixel_height' is used for nominal height.

	* src/base/ftobjs.c (FT_Request_Size): Call `FT_Match_Size' if the
	face is bitmap only and driver doesn't provide `request_size'.  This
	is added merely for completion as no driver satisfies the conditions.

2006-01-13  Chia-I Wu  <b90201047@ntu.edu.tw>

	Introduce new size selection interface.

	functions on Tiger.

	* builds/unix/configure.ac: Add options and autochecks for Carbon
	functions availabilities, for MacOS X.

	* builds/mac/ascii2mpw.py: Add converter for character `\305'.
	* builds/mac/FreeType.m68k_{far|cfm}.make.txt: Add conditional

	* builds/mac/FreeType.ppc_{classic|carbon}.make.txt: Add conditional
	macros to avoid unavailable functions.

	* builds/mac/README: Detailed notes on function availabilities.

2005-12-23  suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Count scalable faces
	in supported formats (sfnt, LWFN) only, and ignore bitmap faces in
	unsupported formats (fbit, NFNT).  The number of available faces are
	passed via face->num_faces.  If bitmap faces are embedded in sfnt
	resource, face->num_fixed_size is correctly set.  In public API,
	FT_New_Face() and FT_New_Face_From_FSSpec() count the faces as
	FT_GetFile_From_Mac_Name(), which ignores NFNT resources.

	* doc/CHANGES: Mention the changes.

	* doc/CHANGES: Mention the changes.

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.

	* 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

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.

	* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
	(TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
	(tt_cmap4_reset): Removed.
	(tt_cmap4_init): Updated accordingly.

	(tt_cmap4_validate): Make sure the subtable is large enough.
	Do not check glyph_ids because some fonts set the length wrongly.
	Also, if 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_cmap12_char_map_binary.
	(tt_face_build_cmaps): Check table and offset correctly (equality is
	missing).

2005-11-15  Detlef Würkner  <TetiSoft@apg.lahn.de>

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

	in the file cache was off by one byte which could cause false
	errors in font files.

	* 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

	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.

	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
	avoid argument expansion by argument prescan.
