freetype2/ChangeLog

2001-02-08  Tom Kacvinsky  <tjk@ams.org>

	* src/cff/cffparse.c (cff_parse_font_matrix): Removed an
	unnecessary fprintf( stderr, ... ).

2001-02-07  Tom Kacvinsky  <tjk@ams.org>

	* src/type1/t1objs.c (T1_Init_Face): Added code to get the
	units_per_EM from the value assigned in parse_font_matrix, if
	available.  Default to 1000 if not available.

	* src/cff/cffparse.c (cff_parse_font_matrix): Added logic to get
	the units_per_EM from the FontMatrix.

	(cff_parse_fixed_thousand): New function. Gets a real number from
	the CFF font, but multiplies by 1000 (this is to avoid rounding
	errors when placing this real number into a 16.16 fixed number).

	(cff_parse_real): Added code so that the integer part is moved
	into the high sixteen bits of the 16.16 fixed number.

	* src/cff/cffobjs.c (CFF_Init_Face): Added logic to get the units
	per EM from the CFF dictionary, if available.

	* include/freetype/internal/cfftypes.h: In struct CFF_Font_Dict_,
	added a units_per_em member to facilitate passing of units_per_em
	from function cff_parse_font_matrix.

	* src/type1/t1load.c (is_alpha): Make `-' a legal alphanumeric
	character.  This is so that font names with `-' are fully parsed,
	etc...

2001-02-02  Werner Lemberg  <wl@gnu.org>

	* src/psaux/psobjs.c (shift_elements): Remove if clause (which is
	obsolete now).

	(reallocate_t1_table, PS_Table_Done): Replace REALLOC() with ALLOC()
	+ MEM_Copy() to avoid a memory bug.

2001-02-01  David Turner  <david.turner@freetype.org>

	* docs/docmaker.py: Improved the index sorting routine to place
	capital letters before small ones.  Added the "<order>" marker to
	section blocks in order to give the order of blocks.

2001-01-30  Antoine Leca  <Antoine.Leca@renault.fr>

	* include/freetype/ttnameid.h: Latest updates to Microsoft language
	ID codes.

2001-01-24  Tom Kacvinsky  <tjk@ams.org>

	* src/cff/t1load.c (parse_font_matrix): Added heuristic to get
	units_per_EM from the font matrix.

	(parse_dict): Deleted test to see whether the FontInfo keyword has
	been seen.  Deletion of this test allows fonts without FontInfo
	dictionaries to be parsed by the Type 1 driver.

	(T1_Open_Face): Deleted empty subroutines array test to make sure
	fonts with no subroutines still are parsed.

2001-01-17  Francesco Zappa Nardelli  <francesco.zappa.nardelli@ens.fr>

	* src/pcfread.c (pcf_get_properties, pcf_get_metrics,
	pcf_get_bitmaps): Fix compiler errors.

	constants from trace_t2xxxx to trace_cffxxxx to be able to compile
	the CFF driver in debug mode.

2001-01-11  Matthew Crosby  <mcrosby@marthon.org>

	* builds/unix/freetype-config.in: Fix problems with separate
	--prefix and --exec-prefix.

2001-01-11  David Turner  <david.turner@freetype.org>

	to include section definitions/delimitations for the API Reference
	generator.

	* include/freetype/freetype.h: Moved declaration of

	(cfferrs.h) instead of t2types.h (t2errors.h, respectively).

	* include/freetype/internal/cfftypes.h: Merged in changes from
	t2types.h and made this the canonical `types' header for the CFF
	driver.

	* include/freetype/internal/t2types.h: This file was merged with
	cfftypes.h and is no longer necessary.

	* include/freetype/internal/t2errors.h:	Renamed to cfferrs.h.

	* src/cff/cffobjs.c, src/cff/cffobjs.h, src/cff/cffparse.c,
	src/cff/cffdrivr.c, src/cff/cff.c, src/cff/cffload.c,
	src/cff/cffgload.c, src/cff/cffgload.h: Changed to use
	cffgload.{c,h} instead of t2gload.{c,h}.  All occurences of t2_

	* include/freetype/internal/t2types.h,
	include/freetype/internal/cfftypes.h: Changed the structures for
	CFF_Encoding and CFF_Encoding for the new implementations of the
	charset and encoding parsers in the CFF driver.

	* src/cff/t2gload.c (t2_lookup_glyph_by_stdcharcode,

	    cff_isoadobe_charset
	    cff_expert_charset
	    cff_expertsubset_charset
	    cff_standard_encoding
	    cff_expert_encoding
	
	so that the encoding/charset parser can handle predefined encodings and
	charsets.

2000-12-24  Tom Kacvinsky  <tjk@ams.org>

	* src/cff/t2gload.c (T2_Load_Glyph): Added code	so that the font
	transform is applied.

	* src/cff/cffparse.c (cff_parse_font_matrix): Added code so that
	the font matrix numbers	are scaled by 1/(matrix->yy).  Also, the

2000-12-21  David Turner  <david.turner@freetype.org>

	* src/cid/cidafm.c, src/cid/cidafm.h: removed un-needed files, 
	we'll work on supporting CID AFM files later I guess :-)

2000-12-21  Tom Kacvinsky  <tjk@ams.org>

	* src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):
	Changed so that fonts with a non-standard FontMatrix render
	correctly.  Previously, the first glyph rendered from such a
	font did not have the tranformation matrix applied.

2000-12-17  Werner Lemberg  <wl@gnu.org>

	* *.mk: Added lots of `.PHONY' targets.

2000-12-17  Karsten Fleischer  <kfleisc1@ford.com>

	* *.mk: Implemented `platform' target to disable auto-detection.

2000-12-14  Werner Lemberg  <wl@gnu.org>

	* docs/design/modules.html: Removed.  Covered by design-*.html.

	* INSTALL: Added info about makepp.

2000-12-14  David Turner  <david.turner@freetype.org>

	Added support for clipped direct rendering in the smooth renderer. 
	This should not break binary compatibility of existing applications.

	* include/freetype/fttypes.h, include/freetype/ftimage.h: Move
	definition of the FT_BBox structure from the former to the latter.
	* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to
	FT_Raster_Flag enumeration.
	Add `clip_box' element to FT_Raster_Params structure.
	* src/smooth/ftgrays.c (grays_convert_glyph): Implement it.
	
	* INSTALL: Updated installation instructions on Win32, listing the
	new "make setup list" target used to list supported
	compilers/targets.

	* src/raster/ftraster.c (ft_black_render): Test for unsupported
	direct rendering before testing arguments.

	* include/freetype/config/ft2build.h,
	include/freetype/internal/internal.h: Fixed header inclusion macros
	to use direct definitions.  This is the only way to do these things
	in a portable way :-(  The rest of the code should follow shortly
	though everything compiles now.
	
	* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.

	* builds/win32/detect.mk: Added support for the Intel C/C++
	compiler, as well as _preliminary_ (read: doesn't work!) support for
	Watcom.  Also added a new setup target.  Type "make setup list" for
	a list of supported command-line compilers on Win32.

	* src/base/ftdebug.c: Added dummy symbol to avoid empty file if
	conditionals are off.

2000-12-13  Werner Lemberg  <wl@gnu.org>

	* builds/unix/ftsystem.c: Fixed typos.  Fixed inclusion of wrong
	ftconfig.h file.

2000-12-12  Werner Lemberg  <wl@gnu.org>

	* include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):
	Removed.  ANSI C doesn't (explicitly) allow macro expansion in
	arguments using `##'.
	(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
	names directly.  Make them configurable.  Use `##' to strip leading
	and trailing spaces from arguments.

	* builds/unix/ft2unix.h: Adapted.

	* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,
	ft_close_stream): Use FT_CALLBACK_DEF.

	* builds/unix/ftsystem.c: Use new header scheme.
	(FT_Done_Memory): Use free() from FT_Memory structure.

	* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.

2000-12-11  Werner Lemberg  <wl@gnu.org>

	* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,
	FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,
	FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.

2000-12-09  Werner Lemberg  <wl@gnu.org>

	* builds/unix/detect.mk: Remove unused USE_CFLAGS variable.

2000-12-08  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttinterp.c: Remove unused CALC_Length() macro.

2000-12-07  David Turner  <david.turner@freetype.org>

2000-12-05  David Turner  <david.turner@freetype.org>

	* src/psaux/psauxmod.c: Fixed a broken inclusion of component
	header files (an FT_FLAT_COMPILE test was missing).

	* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused
	an occasional crash when the function was called (due to a dangling
	pointer).

	* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:
	The ANSI "free()" function was called instead of "memory->free()".

	* docs/docmaker.py: Added section filtering, multi-page generation
	(index page generation is still missing though).

2000-12-04  David Turner  <david.turner@freetype.org>

	* builds/unix/install.mk, builds/unix/ft2unix.h: The file "ft2unix.h"
	is now installed as <ft2build.h> for Unix systems.  Note that we
	still use the "freetype2/freetype" installation path for now.

	* */*.[ch]: Now using <ft2build.h> as the default build and setup
	configuration file in all public headers.  Internal source files
	still need some changes though.

	* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new
	directory to hold all development options for both the Unix and
	Win32 developer builds.

	* builds/win32/detect.mk, builds/win32/w32-bccd.mk,
	builds/win32/w32-dev.mk: Changed the developer build targets to

	`setup'.

2000-11-30  David Turner  <david.turner@freetype.ogr>

	* INSTALL: Slightly updated the quick starter documentation to
	include IDE compilation, prevent against BSD Make, and specify "make
	setup" instead of a single "make" for build configuration.

	* include/config/ftbuild.h, include/internal/internal.h: Added new
	configuration files used to determine the location of all public,
	configuration, and internal header files for FreeType 2.  Modified
	all headers under "include/freetype" to reflect this change.  Note
	that we still need to change the library source files themselves
	though.

	* builds/compiler/bcc.mk, builds/compiler/bcc-dev.mk,
	builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk,
	builds/win32/detect.mk: Added new files to support compilation with
	the free Borland C++ command-line compiler.  Modified the detection
	rules to recognize the new "bcc32" target in "make setup bcc32".

	* src/sfnt/ttcmap.c, src/sfnt/ttpost.c, src/sfnt/ttsbit.c,
	src/truetype/ttobjs.c, src/truetype/ttgload.c,
	src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++
	didn't really like.  Basically, this compiler complains when FT_UInt
	is compared to FT_UShort (apparently, it promotes `UShort' to `Int'
	in these cases).

2000-11-30  Tom Kacvinsky  <tjk@ams.org>

	* t2objs.c (T2_Init_Face): Added calculation of `face->height' for
	pure CFF fonts.

	FTC_Manager_Register_Cache), src/cache/ftcsbits.c
	(FTC_SBit_Cache_Lookup): Ditto.

	* src/include/freetype/cache/ftcglyph.h (FTC_GlyphNode_Init),

2000-11-29  ??? ???  <darin@eazel.com>

	* include/freetype/internal/ftdebug.h: Replaced FT_CAT and FT_XCAT

	width setting code to take into account even/odd argument counts
	and glyph width operand before endchar/hmoveto/vmoveto.

2000-11-26  Werner Lemberg  <wl@gnu.org>

	* builds/ansi/ansi.mk: Fix inclusion order of files.

	* src/type1/t1parse.c (T1_Done_Parse): Renamed to...
	(T1_Finalize_Parser): New function (to avoid name clash with a
	function in the PSAux module).
	(T1_Decrypt): Removed since it is duplicated in the PSAux module.
	(T1_Get_Private_Dict): Added `psaux' as new parameter; use decrypt
	function from PSAux module.

2000-11-22  Tom Kacvinsky  <tjk@ams.org>

	* src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set

	to 1000.

	* src/cff/t2parse.c (parse_t2_real): Fixed real number parsing
	loop.
	
	* src/cff/t2load.c (T2_Get_String): Called T2_Get_Name with a
	sid that was off by one.

2000-11-11  Werner Lemberg  <wl@gnu.org>

	* builds/win32/visualc/freetype.dsp: Fix raster1->raster and
	type1z->type1.

2000-11-11  Tom Kacvinsky  <tjk@ams.org>

	* builds/unix/freetype-config.in, builds/cygwin/freetype-config.in:
	Added a --libtool option.  When freetype-config --libtool is
	invoked, the absolute path to the libtool convenience library
	is returned.
