  47
  482010-02-10  Ken Sharp  <ken.sharp@artifex.com>
  49
  50	Really fix Savannah bug #28678 (part 2).
  51
  52	Since we consider `sbw' for the horizontal direction only, we still have
  53	to synthesize vertical metrics if the user wants to use the vertical
  54	writing direction.
  55
  56	* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
  57	(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
  58	Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
  59	set.
  60
  612010-02-10  Ken Sharp  <ken.sharp@artifex.com>
  62
  63	Really fix Savannah bug #28678 (part 1).
  64
  65	After long discussion, we now consider the character width vector
  66	(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
  67	direction only.  For example, if you are using the horizontal
  68	writing direction, you get the horizontal and vertical components of
  69	the advance width for this direction.  Note that OpenType and CFF fonts
  70	don't have such a vertical component; instead, the GPOS table can be
  71	used to generate two-dimensional advance widths (but this isn't
  72	handled by FreeType).
  73
  74	* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
  75	`advance_v' field to hold the vertical component of the advance
  76	value.
  77
  78	* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
  79	(cff_slot_load), src/type1/t1gload.c
  80	(T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
  81	(cid_load_glyph): Use it.
  82
  832010-02-08  Werner Lemberg  <wl@gnu.org>
  84
  85	* devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define.
  86
  872010-02-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  88
  89	Prevent NULL pointer dereference passed to FT_Module_Requester.
  90
  91	* src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'.
  92	* src/psnames/psmodule.c (psnames_get_interface): Ditto.
  93
  94	* src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'.

 100
 101	* src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings
 102	allocated for face->root.family_name and style_name.
 103
 1042010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
 105
 106	New parameters for FT_Open_Face() to ignore preferred family names.
 107
 108	Preferred family names should be used for legacy systems that
 109	can hold only a few faces (<= 4) for a family name. Suggested by
 110	Andreas Heinrich.
 111	http://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html
 112
 113	* include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
 114	FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define.
 115
 116	* src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and
 117	ignore preferred family and subfamily names if requested.
 118
 1192010-01-27  Ken Sharp  <ken.sharp@artifex.com>

 129
 1302010-01-14  Werner Lemberg  <wl@gnu.org>

 133
 134	* src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation
 135	if no renderer is compiled into the library.
 136
 1372010-01-14  Werner Lemberg  <wl@gnu.org>
 138
 139	Fix compilation warning.
 140
 141	* src/base/ftbase.h: s/LOCAL_DEF/LOCAL/.
 142	* src/base/ftobjc.s: Include ftbase.h conditionally.
 143
 1442010-01-11  Kwang Yul Seo  <skyul@company100.net>
 145
 146	Provide inline assembly code for RVCT compiler.
 147	This is Savannah patch #7059.
 148
 149	* include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
 150	FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.
 151
 1522010-01-08  Ken Sharp  <ken.sharp@artifex.com>
 153
 154	Fix Savannah bug #28521.
 155
 156	Issue #28226 involved a work-around for a font which used the
 157	`setcurrentpoint' operator in an invalid way; this operator is only
 158	supposed to be used with the result of OtherSubrs, and the font used
 159	it directly.  The supplied patch removed the block of code which
 160	checked this usage entirely.
 161
 162	This turns out to be a Bad Thing.  If `setcurrentpoint' is being
 163	used correctly it should reset the flex flag in the decoder.  If we
 164	don't do this then the flag never gets reset and we omit any further
 165	contours from the glyph (at least until we close the path or
 166	similar).
 167
 168	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
 169	<op_setcurrentpoint>: Handle `flex_state' correctly.
 170
 1712010-01-05  Werner Lemberg  <wl@gnu.org>
 172
 173	Apply reports from clang static analyzer.
 174
 175	* src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c
 176	(FT_Stroker_ParseOutline), src/base/ftsynth.c
 177	(FT_GlyphSlot_Embolden): Remove dead code.
 178
 179	* src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
 180	`offset_i' and `length_i'.
 181
 1822010-01-05  Ralph Giles  <giles@ghostscript.com>
 183
 184	Enable the incremental font interface by default.
 185
 186	Ghostscript requires the incremental font interface for handling
 187	some Postscript documents.  It is moving to using FreeType as its
 188	primary renderer; supporting this in the default build makes it
 189	Ghostscript to be linked against the system FreeType when one is
 190	available.
 191
 192	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
 193	Uncomment.
 194
 1952010-01-05  Werner Lemberg  <wl@gnu.org>
 196
 197	Fix Savannah bug #28395.
 198
 199	* src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c
 200	(T1_Loada_Glyph): Don't check `num_glyphs' if incremental interface
 201	is used.
 202
 2032010-01-05  Ken Sharp  <ken.sharp@artifex.com>
 204
 205	Make Type 1 `seac' operator work with incremental interface.
 206	This fixes Savannah bug #28480.
 207
 208	* src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
 209	if incremental interface is used.
 210
 2112010-01-04  Ken Sharp  <ken.sharp@artifex.com>
 212
 213	Make incremental interface work with TrueType fonts.
 214	This fixes Savannah bug #28478.
 215
 216	* src/truetype/ttgload.c (load_truetype_glyph): Don't check
 217	`glyf_offset' if incremental interface is used.
 218
 2192009-12-31  Lars Abrahamsson  <wonko@opera.com>
 220
 221	Make compilation with FT_CONFIG_OPTION_PIC work again.
 222
 223	* src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
 224	Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.
 225
 226	* src/base/ftinit.c (ft_destroy_default_module_classes,
 227	ft_create_default_module_classes): Use proper casts (needed for C++
 228	compilation).
 229
 230	* src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.
 231
 2322009-12-22  Marc Kleine-Budde  <mkl@pengutronix.de>
 233
 234	Make freetype-config aware of $SYSROOT.
 235	This is Savannah patch #7040.
 236
 237	* builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
 238	appropriate.
 239
 2402009-12-20  Werner Lemberg  <wl@gnu.org>
 241
 242	Fix compiler warning.
 243	Reported by Sean.
 244
 245	* src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
 246	source files; however, some compilers warn about an unused variable
 247	declaration.  This is now replaced with a typedef.
 248
 2492009-12-18  Werner Lemberg  <wl@gnu.org>
 250
 251	Fix Savannah bug #28320.
 252
 253	There exist corrupt, subsetted fonts (embedded in PDF files) which
 254	contain a private dict that ends with an unterminated floating point
 255	number (no operator following).  We now ignore this error (as
 256	acrobat does).
 257
 258	* src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
 259	unterminated floating point numbers.
 260
 2612009-12-16  Werner Lemberg  <wl@gnu.org>

 263	Really fix compiler warnings.
 264	Reported by Sean.
 265
 266	* src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS,
 267	GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.
 268
 2692009-12-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
 270
 271	Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
 272	The linker of Mac OS X 10.6 is sensitive to the architecture.  If
 273	the architectures are specified explicitly for the C compiler, the
 274	linker requires the architecture specifications too.
 275
 276	* builds/unix/configure.raw: Replace `-isysroot' option parser by
 277	more generic argument parser.
 278
 2792009-12-15  Werner Lemberg  <wl@gnu.org>
 280
 281	Fix compiler warnings.
 282	Reported by Sean.
 283
 284	* src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data
 285	type.
 286
 2872009-12-14  Ken Sharp  <ken.sharp@artifex.com>
 288
 289	Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
 290	This fixes Savannah bug #28226.
 291
 292	At least two wild PostScript files of unknown provenance contain
 293	Type 1 fonts, apparently converted from TrueType fonts in earlier
 294	PDF versions of the files, which use the `setcurrentpoint' operator
 295	inappropriately.
 296
 297	FreeType currently throws an error in this case, but Ghostscript and
 298	Adobe Distiller both accept the fonts and ignore the problem.  This
 299	commit #ifdefs out the check so PostScript interpreters using
 300	FreeType can render these files.
 301
 302	The specification says `setcurrentpoint' should only be used to set
 303	the point after a `Subr' call, but these fonts use it to set the
 304	initial point to (0,0).  Unnecessarily so, as they correctly use an
 305	`hsbw' operation which implicitly sets the initial point.
 306
 307	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
 308	<op_setcurrentpoint>: Comment out code.
 309
 3102009-12-14  Bram Tassyns  <bramt@enfocus.be>
 311
 312	Fix parsing of /CIDFontVersion.
 313	This fixes Savannah bug #28287.
 314
 315	* src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in
 316	t1tables.h) is of type FT_Fixed.
 317
 3182009-12-14  Werner Lemberg  <wl@gnu.org>
 319
 320	Trace glyph index in CID module.
 321	Suggested in Savannah patch #7023.

 527	[cache] Fix Savannah bug #27441, clean up Redhat bugzilla #513582.
 528	Tricky casts in FTC_{CACHE,GCACHE,MRULIST}_LOOKUP_CMP() are removed.
 529	Now these functions should be called with FTC_Node or FTC_MruNode
 530	variable, and the caller should cast them to appropriate pointers to
 531	concrete data.  These tricky casts can GCC-4.4 optimizer (-O2)
 532	confused and the crashing binaries are generated.
 533
 534	* src/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Drop tricky cast.
 535	Now the 4th argument `node' of this function should be typed as
 536	FTC_MruNode.
 537
 538	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): For inline
 539	implementation, new temporal variable FTC_MruNode `_mrunode' to take
 540	the pointer from FTC_MRULIST_LOOKUP_CMP().  For non-inline
 541	implementation, tricky cast is dropped.
 542
 543	* src/cache/ftcmanag.c (FTC_SIZE_NODE): New macro casting
 544	to FTC_SizeNode.
 545	(FTC_Manager_LookupSize): Replace FTC_SizeNode `node' by FTC_MruNode
 546	`mrunode', and FTC_SIZE_NODE() is inserted.
 547	(FTC_FACE_NODE): New macro casting to FTC_FaceNode.
 548	(FTC_Manager_LookupFace) Replace FTC_FaceNode `node' by FTC_MruNode
 549	`mrunode', and FTC_FACE_NODE() is inserted.
 550
 551	* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Change the type of
 552	`node' from FTC_INode to FTC_Node.  Extra casting macro FTC_NODE()
 553	is dropped.
 554	(FTC_ImageCache_LookupScaler): Ditto.
 555	(FTC_SBitCache_Lookup): Change the type of `node' from FTC_SNode to
 556	FTC_Node.  Extra casting macro FTC_NODE() is dropped.  FTC_SNODE()

 614
 615	Improve configure.raw for cross build.
 616
 617	* builds/unix/configure.raw: Remove temporal files created by the
 618	suffix checking for CC_BUILD.  Set XX_ANSIFLAGS and XX_CFLAGS when
 619	cross compiler is GCC.  AC_PROG_CC checks whether the cross compiler
 620	is GCC, its result is stored in GCC.

 623
 624	[BDF] Modify hash API to take size_t value instead of void *.
 625
 626	The hash API in BDF driver is designed to be generic, it takes
 627	void * typed data.  But BDF driver always gives an unsigned long
 628	integer (the index to a property).  To reduce non-essential
 629	casts from unsigned long to void* and from void* to unsigned
 630	long, the hash API is changed to take size_t integer.
 631	The issue of incompatible cast between unsigned long and void*
 632	on LLP64 platform is reported by NightStrike from MinGW-Win64
 633	project.  See
 634	http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
 635
 636	* src/bdf/bdf.h: The type of hashnode->data is changed from
 637	void* to size_t.
 638
 639	* src/bdf/bdflib.c (hash_insert): Get size_t data, instead of
 640	void* data.
 641	(bdf_create_property): Get the name length of new property by
 642	size_t variable, with a cut-off at FT_ULONG_MAX.
 643	(_bdf_set_default_spacing): Get the name length of the face by
 644	size_t variable, with a cut-off at 256.
 645	(bdf_get_property): Get the property id by size_t variable to
 646	reduce the casts between 32-bit prop ID & hashnode->data during
 647	simple copying.
 648	(_bdf_add_property): Ditto.
 649	(_bdf_parse_start): Calculate the index to the property array
 650	by size_t variable.
 651	(bdf_get_font_property): Drop a cast to unsigned long.

 655	[Win64] Improve the computation of random seed from stack address.
 656
 657	On LLP64 platform, the conversion from pointer to FT_Fixed need
 658	to drop higher 32-bit.  Explict casts are required. Reported by
 659	NightStrike from MinGW-w64 project.  See
 660	http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
 661

 678
 679	Improve vertical metrics calculation (Savannah bug #27364).
 680
 681	The calculation of `vertBearingX' is not defined in the OTF font
 682	spec so FreeType does a `best effort' attempt.  However, this value
 683	is defined in the PDF and PostScript specs, and that algorithm is
 684	better than the one FreeType currently uses:
 685
 686	  FreeType: Use the middle of the bounding box as the X coordinate
 687	            of the vertical origin.
 688
 689	  Adobe PDF spec: Use the middle of the horizontal advance vector as
 690	                  the X coordinate of the vertical origin.
 691
 692	FreeType's algorithm goes wrong if you have a really small glyph
 693	(like the full-width, circle-like dot at the end of the sentence, as
 694	used in CJK scripts) with large bearings.  With the FreeType
 695	algorithm this dot gets centered on the baseline; with the PDF
 696	algorithm it gets the correct location (in the top right).  Note
 697	that this is a serious issue, it's like printing the dot at the end
 698	of a Roman sentence at the center of the textline instead of on the
 699	baseline like it should. So i believe the PDF spec's algorithm
 700	should be used in FreeType as well.
 701
 702	The `vertBearingY' value for such small glyphs is also very strange
 703	if no `vmtx' information is present, since the height of the bbox is
 704	not representable for the height of the glyph visually (the
 705	whitespace up to the baseline is part of the glyph).  The fix also
 706	includes some code for a better estimate of `vertBearingY'.
 707
 708	* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
 709	is now calculated as described by the Adobe PDF Spec.  Estimate for
 710	`vertBearingY' now works better for small glyphs completely above or
 711	below the baseline into account.
 712
 713	* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
 714	calculated as described by the Adobe PDF Spec.  Vertical metrics
 715	information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
 716	was not defined.
 717
 718	* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
 719	now calculated as described by the Adobe PDF Spec.

1885
1886	* src/truetype/ttobjs.c (tt_size_init_bytecode): Don't reset x_ppem

1913	Define TE = `-e' separately (bcc32 cannot specify the pathname of
1914	binary executable by T = `-o').
1915	Extend the large page size in linking freetype.lib.

1926
1927	Add a script to check the undefined and unused trace macros.
1928
1929	* src/tools/chktrcmp.py: A script to check trace_XXXX macros
1930	that are used in C source but undefined in fttrace.h, or
1931	defined in fttrace.h but unused in C sources.  See
1932	http://lists.gnu.org/archive/html/freetype-devel/2009-07/msg00013.html.

1947
1948	smooth: Check glyph size by width/height, instead of pitch/height.
1949	Suggested by der Mouse <mouse@Rodents-Montreal.ORG>.
1950
1951	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Improve
1952	the check for too large glyph.  Replace the pair of `pitch' and
1953	`height' by the pair of `width' and `height'.  `pitch' cannot
1954	be greater than `height'.  The required is checking the product
1955	`pitch' * `height' <= FT_ULONG_MAX, but we use cheap checks for
1956	the realistic case only.
1957
19582009-07-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
1959

1982	FT_OUTLINE_POINTS_MAX): New macros to declare the maximum
1983	values of FT_Outline.{n_contours,n_points}.
1984	* src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Check the
1985	total numbers of points and contours cause no overflows in
1986	FT_Outline.{n_contours,n_points}.
1987
1988	* include/freetype/internal/ftgloadr.h (FT_GLYPHLOADER_CHECK_P,
1989	FT_GLYPHLOADER_CHECK_C): Compare the numbers of points and
1990	contours as unsigned long number, instead of signed int, to
1991	prevent the overflows on 16-bit systems.
1992
19932009-07-05  Bram Tassyns  <bramt@enfocus.be>
1994
1995	Improve compatibility to Acroread.
1996	This fixes Savannah bug #26944.

2039
2040	Add tools to preprocess the source files for AtariST PureC.

2043	for broken C preprocessor of PureC compiler.
2044
2045	* builds/atari/gen-purec-patch.sh: New file to generate a patch set

2049
2050	Keep existing modules.cfg in the building tree.
2051
2052	* configure: If `configure' is executed outside of the source tree,
2053	an existing `modules.cfg' file in the build directory should be
2054	kept, not overwritten by the version in the source tree.
2055
20562009-06-27  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
2057
2058	Filter --srcdir= option before invoking builds/unix/configure.
2059
2060	* configure: If builds/unix/configure is invoked with --srcdir
2061	option, the option should take `builds/unix' directory instead of
2062	the top source directory.  Thus the configure script in the top
2063	directory should modify the --srcdir= option if
2064	`builds/unix/configure' is invoked.
2065
20662009-06-27  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

20802009-06-26  Werner Lemberg  <wl@gnu.org>
2081
2082	* */*: For warning messages, replace FT_ERROR with FT_TRACE0.
2083
2084	FT_ERROR is now used only if a function produces a non-zero `error'
2085	value.
2086
2087	Formatting, improving and harmonizing debug strings.
2088
20892009-06-25  Werner Lemberg  <wl@gnu.org>

2096
20972009-06-22  Werner Lemberg  <wl@gnu.org>
2098
2099	Use 16.16 format while parsing Type 1 charstrings.
2100	This fixes Savannah bug #26867.
2101
2102	Previously, only integers have been used which can lead to serious
2103	rounding errors.
2104
2105	However, fractional values are only used internally; after the
2106	charstrings (of either Type 1 or 2) have been processed, the
2107	resulting coordinates get rounded to integers currently -- before
2108	applying scaling.  This should be fixed; at the same time a new load
2109	flag should be introduced, to be used in combination with
2110	FT_LOAD_NO_SCALE, which indicates that font units are returned in
2111	16.16 format.  Similarly, the incremental interface should be
2112	extended to allow fractional values for metrics.
2113
2114	* include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift'
2115	field.
2116	* include/freetype/internal/pshints.h (T1_Hints_SetStemFunc,

2120	(t1_build_add_point): Always convert fixed to integer.
2121	* src/psaux/t1decode.c (t1_decoder_parse_charstrings):
2122	Use 16.16 format everywhere (except for large integers followed by a
2123	`div').
2124	[CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate
2125	code uncoditionally.
2126	Add support for random numbers and update remaining code
2127	accordingly; this should work now.
2128	(t1_operator_seac): Updated.
2129	* src/psaux/pshrec.c: Include FT_INTERNAL_CALC_H.
2130	(ps_hints_t1stem3, t1_hints_stem): Updated.

2137	[FT_CONFIG_OPTION_INCREMENTAL], (T1_Get_Advances, T1_Load_Glyph):

2148	Code beautification.
2149

2151	Replace everywhere with INT_TO_FIXED.
2152	(FT_FIXED_TO_INT): Move to ...
2153	* include/freetype/internal/ftcalc.h (FIXED_TO_INT): Here.

2217	Fix B/W rasterization of subglyphs with different drop-out modes.
2218
2219	Normally, the SCANMODE instruction (if present) to set the drop-out
2220	mode in a TrueType font is located in the `prep' table only and thus
2221	valid for all glyphs.  However, there are fonts like `pala.ttf'
2222	which additionally contain this instruction in the hinting code of
2223	some glyphs (but not all).  As a result it can happen that a
2224	composite glyph needs multiple drop-out modes for its subglyphs
2225	since the rendering state gets reset for each subglyph.
2226
2227	FreeType collects the hinted outlines from all subglyphs, then it
2228	sends the data to the rasterizer.  It also sends the drop-out mode
2229	-- after hinting has been applied -- and here is the error: It sends
2230	the drop-out mode of the last subglyph only; drop-out modes of all
2231	other subglyphs are lost.
2232
2233	This patch fixes the problem; it adds a second, alternative
2234	mechanism to pass the drop-out mode: For each contour, the
2235	rasterizer now checks the first `tags' array element.  If bit 2 is
2236	set, bits 5-7 contain the contour's drop-out mode, overriding the
2237	global drop-out mode.
2238
2239	* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
2240
2241	* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
2242	`tags[0]'.
2243
2244	* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
2245	Use bits 3-5 instead of 0-2.
2246	(New_Profile): Set the drop-out mode in the profile's `flags' field.
2247	(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
2248	necessary.
2249	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
2250	Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
2251	mode.
2252
22532009-06-16  Werner Lemberg  <wl@gnu.org>
2254
2255	Improve scan conversion rules 4 and 6.
2256
2257	Two new constraints are introduced to better identify a `stub' -- a
2258	concept which is only vaguely described in the OpenType
2259	specification.  The old code was too rigorous and suppressed more
2260	pixel than it should.
2261
2262	  . The intersection of the two profiles with the scanline is less
2263	    than a half pixel.  Code related to this was already present in
2264	    the sources but has been commented out.
2265
2266	  . The endpoint of the original contour forming a profile has a
2267	    distance (`overshoot') less than half a pixel to the scanline.
2268
2269	Note that the two additional conditions fix almost all differences
2270	to the Windows rasterizer, but some problematic cases remain.
2271
2272	* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
2273	macros for the `flags' field in the `TProfile' structure.
2274	(IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
2275	(New_Profile, End_Profile): Pass overshoot flag as an argument and
2276	set it accordingly.
2277	Update callers.
2278	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
2279	constraints.
2280
22812009-06-11  Werner Lemberg  <wl@gnu.org>

2283	Increase precision for B/W rasterizer.
2284
2285	* src/raster/ftraster.c (Set_High_Precision): Add two more bits to
2286	the precision.  This corrects rendering of some small glyphs, for
2287	example, glyph `xi' in verdana.ttf at 13 ppem.  Testing with ftbench
2288	on my GNU/Linux box I don't see a performance degradation.

3129
31302009-03-09  Alexey Kryukov  <anagnost@yandex.ru>
3131
3132	Fix handling of EBDT formats 8 and 9 (part 2).
3133
3134	This patch fixes the following problems in ttsbit0.c:
3135
3136	. Bitmaps for compound glyphs were never allocated.
3137
3138	. `SBitDecoder' refused to load metrics if some other metrics have
3139	  already been loaded.  This condition certainly makes no sense for
3140	  recursive calls, so I've just disabled it.  Another possibility
3141	  would be resetting `decoder->metrics_loaded' to false before
3142	  loading each composite component.  However, we must restore the
3143	  original metrics after finishing the recursion; otherwise we can
3144	  get a misaligned glyph.
3145
3146	. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
3147	  causing some glyph components to be shifted too far to the right
3148	  (especially noticeable for small sizes).
3149
3150	Note that support for grayscale bitmaps (not necessarily compound) is
3151	completely broken in ttsbit0.c.
3152
3153	* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
3154	(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
3155	of `h == height'.
3156	(tt_sbit_decoder_load_compound): Reset metrics after loading
3157	components.
3158	Allocate bitmap.

3185
3186	Instead, we define a new internal PS_FontExtraRec structure to
3187	hold the additional field, then place it in various internal
3188	positions of the corresponding FT_Face derived objects.
3189
3190	* include/freetype/t1tables.h (PS_FontInfoRec): Remove the

3221
3222	Fix handling of EBDT formats 8 and 9.
3223
3224	The main cycle in `blit_sbit' makes too many iterations: it actually
3225	needs the count of lines in the source bitmap rather than in the
3226	target image.
3227
3228	* src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]:

3537	  extern const FT_Module_Class
3538
3539	(or similar for C++).  However, the actual types of the variables
3540	being declared are often different, e.g., FT_Driver_ClassRec or
3541	FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)
3542
3543	This works with most C compilers (since those structs begin with an
3544	FT_Module_Class struct), but technically it's undefined behavior.
3545
3546	To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
3547	paragraph 2:
3548
3549	  All declarations that refer to the same object or function shall
3550	  have compatible type; otherwise, the behavior is undefined.
3551
3552	(And they are not compatible types.)
3553
3554	Most C compilers don't reject (or even detect!) code which has this
3555	issue, but the GCC LTO development branch compiler does.  (It
3556	outputs the types of the objects while generating .o files, along
3557	with a bunch of other information, then compares them when doing the
3558	final link-time code generation pass.)
3559
3560	Patch from Savannah bug #25133.
3561
3562	* src/base/ftinit.c (FT_USE_MODULE): Include variable type.
3563
3564	* builds/amiga/include/freetype/config/ftmodule.h,
3565	include/freetype/config/ftmodule.h, */module.mk: Updated to declare
3566	pass correct types to FT_USE_MODULE.

3595
3596	* include/freetype/t1tables.h (PS_FontInfoRec): Add `fs_type' field.
3597
35982008-12-17  Werner Lemberg  <wl@gnu.org>
3599
3600	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Don't use internal
3601	macros so that copying the source code into an application works
3602	out of the box.
3603
36042008-12-17  Werner Lemberg  <wl@gnu.org>
3605
3606	* include/freetype/ftsynth.h, src/base/ftsynth.c: Move

3611
36122008-12-10  Werner Lemberg  <wl@gnu.org>
3613
3614	Generalize the concept of `tricky' fonts by introducing
3615	FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
3616	engine is necessary for correct rendering.
3617
3618	At the same time, slightly modify the behaviour of tricky fonts:
3619	FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
3620	of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
3621	FT_LOAD_NO_AUTOHINT must be used.
3622
3623	Finally, tricky TrueType fonts always use the bytecode interpreter
3624	even if the patented code is used.
3625
3626	* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):

3633	code of ...
3634	(tt_face_init): This function, now simplified and updated to new
3635	semantics.
3636
3637	* src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
3638	fonts.
3639
3640	* docs/CHANGES: Document it.
3641
36422008-12-09  Werner Lemberg  <wl@gnu.org>
3643
3644	Really fix Savannah bug #25010: An SFNT font with neither outlines
3645	nor bitmaps can be considered as containing space `glyphs' only.
3646
3647	* src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
3648	a `glyf' table is missing.
3649
3650	* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
3651	`glyf' table but a non-zero `loca' entry.
3652	(tt_loader_init): Handle missing `glyf' table.
3653
3654	* src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.
3655
3656	* src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines
3657	nor bitmaps is scalable.
3658

3660
3661	* src/autofit/aflatin.c (af_latin_uniranges): Add more ranges.  This
3662	fixes Savannah bug #21190 which also provides a basic patch.
3663
36642008-12-05  Werner Lemberg  <wl@nu.org>
3665
3666	* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value
3667	0x100 instead of 0x10000; the latter value is already occupied by
3668	FT_LOAD_TARGET_LIGHT.  Bug reported by James Cloos.
3669
3670
3671	Handle SFNT with neither outlines nor bitmaps.  This fixes Savannah
3672	bug #25010.
3673
3674	* src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
3675	outlines nor bitmaps.

3678	is no table with glyphs.
3679
3680

3701
37022008-11-29  James Cloos  <cloos@jhcloos.com>
3703
3704	* src/type/t1load.c (mm_axis_unmap): Revert previous patch and fix

3706	in the /BlendDesignMap space).
3707
37082008-11-29  James Cloos  <cloos@jhcloos.com>
3709
3710	* src/type1/t1load.c (mm_axis_unmap): `blend_points' is FT_Fixed*,
3711	whereas `design_points' is FT_Long*.  Therefore, return blend rather
3712	than design points.
3713

3822
3823	According to include/freetype/internal/ftobjs.h, the appropriate

3939	(FREETYPE_H): Updated.
3940	* src/base/rules.mk: (BASE_OBJ_S, OBJ_DIR/%.$O): Add BASE_H.
3941	* src/bdf/rules.mk (BDF_DRV_H): Add bdferror.h.
3942	* src/cache/rules.mk (CACHE_DRV_H): Add ftccache.h and ftcsbits.h.
3943	* src/pcf/rules.mk (PCF_DRV_H): Add pcfread.h.
3944	* src/raster/rules.mk (RASTER_DRV_H): Add ftmisc.h.
3945	* src/type42/rules.mk (T42_DRV_H): Add t42types.h.
3946
39472008-10-02  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
3948
3949	* src/base/ftbase.h: New file to declare the private utility
3950	functions shared by the sources of base modules.  Currently,
3951	`ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
3952	share between ftobjs.c and ftmac.c.
3953
3954	* src/base/rule.mk: Add ftbase.h.
3955
3956	* src/base/ftobjs.c: Include ftbase.h.
3957	(memory_stream_close): Build on any platform when old MacOS font
3958	support is enabled.
3959	(new_memory_stream): Ditto.
3960	(open_face_from_buffer): Build on any platform when old MacOS font
3961	support is enabled.  The counting of the face in a font file is
3962	slightly different between Carbon-dependent parser and Carbon-free
3963	parser.  They are merged with the platform-specific conditional.
3964	(ft_lookup_PS_in_sfnt): Ditto.
3965
3966	* src/base/ftmac.c: Include ftbase.h.
3967	(memory_stream_close): Removed.
3968	(new_memory_stream): Ditto.
3969	(open_face_from_buffer): Removed.  Use the implementation in
3970	ftobjs.c.
3971	(ft_lookup_PS_in_sfnt): Ditto.
3972
39732008-10-02  Werner Lemberg  <wl@gnu.org>
3974
3975	* src/sfnt/sfobjs.c (sfnt_load_face): `psnames_error' is only needed
3976	if TT_CONFIG_OPTION_POSTSCRIPT_NAMES is defined.
3977
39782008-10-01  Werner Lemberg  <wl@gnu.org>
3979
3980	* src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c
3981	(cff_face_done), src/pfr/pfrobjs.c (pfr_face_done),
3982	src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c
3983	(cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done),
3984	src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0.
3985	Reported by Graham Asher.
3986
39872008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
3988
3989	* src/base/rules.mk: Add conditional source to BASE_SRC, for `make
3990	multi' on Mac OS X.  If the macro $(ftmac_c) is defined,
3991	$(BASE_DIR)/$(ftmac_c) is added to BASE_SRC.  In a normal build, the
3992	lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
3993	ftmac.c.
3994	* builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
3995	* builds/unix/configure.raw: Add procedure to set up appropriate
3996	value of $(ftmac_c) with the consideration of the availability of
3997	Carbon framework.
3998
39992008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4000
4001	* src/base/Jamfile: Add target for multi build by jam on Mac OS X.
4002	* src/base/ftobjs.c (FT_New_Face): Fix the condition to include this
4003	function for MPW building.  It is synchronized the condition to
4004	include ftmac.c source into ftbase.c.
4005
40062008-09-22  Werner Lemberg  <wl@gnu.org>
4007
4008	* src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
4009	cff_decoder_parse_charstrings): Handle (invalid)
4010	`callothersubr' and `pop' instructions.
4011
40122008-09-22  John Tytgat  <John.Tytgat@esko.com>
4013
4014	Fix Savannah bug #24307.
4015

4017	src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.
4018
40192008-09-21  Werner Lemberg  <wl@gnu.org>
4020
4021	* src/smooth/ftgrays.c (gray_raster_render): Don't dereference
4022	`target_map' if FT_RASTER_FLAG_DIRECT is set.  Problem reported by
4023	Stephan T. Lavavej <stl@nuwen.net>.
4024
40252008-09-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4026
4027	* src/otvalid/Jamfile: Add missing target `otvmath' for multi build
4028	by jam.
4029	* src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
4030	jam.
4031
40322008-09-20  Werner Lemberg  <wl@gnu.org>
4033
4034	* src/smooth/ftgrays.c (gray_find_cell): Fix threshold.  The values
4035	passed to this function are already `normalized'.  Problem reported
4036	by Stephan T. Lavavej <stl@nuwen.net>.
4037
4038	* docs/CHANGES: Document it.
4039
40402008-09-20  Werner Lemberg  <wl@gnu.org>
4041
4042	* src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
4043	(FT_Outline_Decompose): Decorate with tracing messages.
4044
4045	* src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
4046	FT_DEBUG_LEVEL_TRACE.
4047	[_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
4048	stdarg.h.

4056	Use FT_TRACE7.
4057	(gray_dump_cells): Make it `static void'.
4058	(gray_convert_glyph): Use FT_TRACE7.
4059
4060	(FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
4061	ftoutln.c.
4062
4063	* src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
4064	FT_ERROR_BASE.
4065
4066	* docs/formats.txt: Updated.
4067
40682008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4069
4070	* src/base/ftmac.c: Import sfnt-wrapped Type1 and sfnt-wrapped
4071	CID-keyed font support.
4072	* builds/mac/ftmac.c: Ditto.
4073
40742008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4075
4076	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
4077	sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
4078	`open_face_from_buffer' frees the passed buffer if it cannot open a
4079	face from the buffer, so the caller must not free it.
4080
40812008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4082
4083	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
4084	for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
4085	(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '
4086	table in sfnt table directory.  It is used before loading TrueType
4087	font driver.
4088
4089	* docs/CHANGES: Add note about the current status of sfnt-wrapped
4090	Type1 and sfnt-wrapped CID-keyed font support.
4091
40922008-09-18  Werner Lemberg  <wl@gnu.org>
4093
4094	* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
4095	orthogonality (ft_free and ft_sfree could belong to different memory
4096	pools).  This fixes Savannah bug #24297.
4097
40982008-09-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4099
4100	* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
4101	in ttags.h instead of numerical value 0x4F54544FL.
4102
41032008-09-16  Werner Lemberg  <wl@gnu.org>
4104
4105	* src/cff/cffgload.h, src/cff/cffgload.c
4106	(cff_decoder_set_width_only): Eliminate function call.
4107
41082008-09-15  George Williams  <gww@silcom.com>
4109
4110	Fix Savannah bug #24179, reported by Bram Tassyns.
4111
4112	* src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
4113	of default values.
4114
41152008-09-15  Werner Lemberg  <wl@gnu.org>
4116
4117	* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
4118	and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
4119	prevent unconditional definition.  This fixes Savannah bug #24241.
4120
4121	* src/psnames/pstables.h: Regenerated.
4122
41232008-09-13  Werner Lemberg  <wl@gnu.org>
4124
4125	* autogen.sh, builds/unix/configure.raw,
4126	include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
4127	beautifying.
4128
4129	* include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
4130	include/freetype/ftlcdfil.h: Protect against FreeType 1.
4131	Some other minor fixes.
4132
4133	* devel/ftoption.h: Synchronize with
4134	include/freetype/config/ftoption.h.
4135
41362008-09-11  Werner Lemberg  <wl@gnu.org>
4137
4138	* src/base/ftbase.c: Include ftadvanc.c.
4139
41402008-09-11  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4141
4142	* builds/unix/ftconfig.in: Duplicate the cpp computation of
4143	FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
4144	(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp
4145	computation is disabled and the statically configured sizes are
4146	used.  This fixes Savannah bug #21250.
4147
4148	* builds/unix/configure.raw: Add the checks to compare the cpp
4149	computation results of the bit length of int and long versus the
4150	sizes detected by running `configure'.  If the results are
4151	different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
4152	results.
4153	New option --{enable|disable}-biarch-config is added to define or
4154	undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
4155
41562008-09-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4157
4158	* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
4159	ApplicationService framework is missing.  Although this value is not
4160	used in building of FreeType2, it is written in `freetype2.pc' and
4161	`freetype-config'.
4162
41632008-09-01  david turner  <david@freetype.org>
4164
4165	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
4166	index to mean `use default cached FT_Face's charmap'.  This fixes
4167	Savannah bug #22625.
4168	* include/freetype/ftcache.h: Document it.
4169
4170
4171	Make FT_MulFix an inlined function.  This is done to speed up
4172	FreeType a little (on x86 3% when loading+hinting, 10% when
4173	rendering, ARM savings are more important though).  Disable this by
4174	undefining FT_CONFIG_OPTION_INLINE_MULFIX.
4175
4176	Use of assembler code can now be controlled with
4177	FT_CONFIG_OPTION_NO_ASSEMBLER.
4178
4179	* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
4180	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler
4181	implementation.
4182	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler
4183	implementation taken from `ftcalc.c'.
4184	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
4185	which is defined to the platform-specific assembler implementation
4186	of FT_MulFix.
4187	[FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
4188	(FT_MULFIX_INLINED): New macro.
4189
4190	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
4191	FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
4192
4193	* include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
4194
4195	* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
4196	FT_MULFIX_INLINED.
4197
4198
4199	Add a new header named FT_ADVANCES_H declaring some new APIs to
4200	extract the advances of one or more glyphs without necessarily
4201	loading their outlines.  Also provide `fast loaders' for the
4202	TrueType, Type1, and CFF font drivers (more to come later).
4203
4204	* src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
4205
4206	* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
4207	* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.
4208
4209	* include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
4210	`flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
4211	respectively.
4212
4213	* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add
4214	ftadvanc.c.
4215
4216	* src/cff/cffdrivr.c (cff_get_advances): New function.
4217	(cff_driver_class): Register it.
4218
4219	* src/cff/cffgload.c (cff_decoder_set_width_only): New function.
4220	(cff_decoder_parse_charstrings): Handle `width_only'.
4221	(cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.
4222
4223	* src/cff/cffgload.h (cff_decoder): New element `width_only'.
4224	(cff_decoder_set_width_only): New declaration.
4225
4226	* src/truetype/ttdriver.c (tt_get_advances): New function.
4227	(tt_driver_class): Register it.
4228
4229	* src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
4230	(TT_Get_HMetrics, TT_Get_VMetrics): This.
4231	Update callers.
4232	* src/truetype/ttgload.h: Declare them.
4233
4234	* src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
4235	function.
4236	* src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.
4237
4238
4239	Add checks for minimum version of the `autotools' stuff.
4240
4241	* autogen.sh: Implement it.
4242	(get_major_version, get_minor_version, get_patch_version,
4243	compare_to_minimum_version, check_tool_version): New auxiliary
4244	functions.
4245
4246	* README.CVS: Document it.
4247
42482008-08-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4249
4250	* src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
4251	ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).
4252
42532008-08-28  Werner Lemberg  <wl@gnu.org>
4254
4255	* src/type1/t1load.c (parse_encoding): Protect against infinite
4256	loop.  This fixes Savannah bug #24150 (where a patch has been posted
4257	too).
4258
42592008-08-23  Werner Lemberg  <wl@gnu.org>
4260
4261	* src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
4262	(afm_compare_kern_pairs): Fix comparison.  This fixes Savannah bug
4263	#24119.
4264
42652008-08-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4266
4267	* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
4268	even if passed library or arguments are invalid.  This fixes a bug
4269	that an uninitialized stream is freed when an invalid library handle
4270	is passed.  Originally proposed by Mike Fabian, 2008/08/18 on
4271	freetype-devel.
4272	(FT_Open_Face): Ditto (stream).
4273	(load_face_in_embedded_rfork): Ditto (stream2).
4274
42752008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4276
4277	* src/base/ftmac.c: Add a fallback to guess the availability of the
4278	`ResourceIndex' type.  It is used when built without configure
4279	(e.g., a build with Jam).
4280	* builds/mac/ftmac.c: Ditto.
4281	* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
4282	explicitly, even if `ResourceIndex' is unavailable.
4283
42842008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4285
4286	* builds/unix/configure.raw: In checking of Mac OS X features,
4287	all-in-one header file `Carbon.h' is replaced by the minimum
4288	header file `CoreServices.h', similar to current src/base/ftmac.c.
4289
42902008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4291
4292	* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
4293	sub-header when its code_count is 0.  Many Japanese Dynalab fonts
4294	include such an empty sub-header (code_count == 0, first_code == 0
4295	delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
4296
42972008-08-04  Werner Lemberg  <wl@gnu.org>
4298
4299	* src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes
4300	Savannah bug #23995.
4301
4302	* src/cid/cidload.c (parse_expansion_factor): New callback function.
4303	(cid_field_records): Use it for `ExpansionFactor'.
4304	* src/cod/cidtoken.h: Handle `ForceBold' keyword.
4305	Don't handle `ExpansionFactor'.
4306
43072008-08-04  Bram Tassyns  <bramt@enfocus.be>
4308
4309	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
4310	resulted in incorrect scaling.  This fixes Savannah bug #23973.
4311
43122008-08-04  Werner Lemberg  <wl@gnu.org>
4313
4314	Be more tolerant w.r.t. invalid entries in SFNT table directory.
4315
4316	* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
4317	adjust table count.
4318	Add more trace messages.
4319	(tt_face_load_font_dir): Updated.
4320
43212008-07-30  Werner Lemberg  <wl@gnu.org>
4322
4323	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
4324	assume that the first argument on the stack is the bottom-most
4325	element.  Two reasons:
4326
4327	  o According to people from Adobe it is missing in the Type 2
4328	    specification that pushing of additional, superfluous arguments
4329	    on the stack is prohibited.
4330
4331	  o Acroread in general handles fonts differently, namely by popping
4332	    the number of arguments needed for a particular operand (as a PS
4333	    interpreter would do).  In case of buggy fonts this causes a
4334	    different interpretation which of the elements on the stack are
4335	    superfluous and which not.
4336
4337	Since there are CFF subfonts (embedded in PDFs) which rely on
4338	Acroread's behaviour, FreeType now does the same.
4339
43402008-07-27  Werner Lemberg  <wl@gnu.org>
4341
4342	Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This
4343	fixes Savannah bug #23940.
4344
4345	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
4346	(EXTRA_GLYPH_LIST_SIZE): This.
4347	Increase by 2.

4371	tt_cmap4_char_map_binary): Handle fonts which treat the last segment
4372	specially.  According to the specification, such fonts would be
4373	invalid but acroread accepts them.
4374
43752008-07-16  Jon Foster  <Jon.Foster@cabot.co.uk>
4376
4377	* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

4398
4399	* src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
4400	where num_locations < num_glyphs.  Problem reported by Ding Li.
4401
44022008-07-05  Werner Lemberg  <wl@gnu.org>
4403
4404	Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
4405	newer.  This fixes Savannah bug #23648.
4406
4407	* configure: zsh doesn't like ${1+"$@"}.
4408	Update needed GNU make version.
4409	* builds/toplevel.mk: Check for `$(eval ...)'.
4410	* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
4411	it.
4412
44132008-07-04  Werner Lemberg  <wl@gnu.org>
4414
4415	* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
4416	pixel, only check for dropouts if neither start nor end point lies

4444
4445	* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
4446	* src/ftcalc.c: Here.  This fixes Savannah bug #23729.
4447
44482008-06-27  Werner Lemberg  <wl@gnu.org>
4449
4450	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
4451	Horizontal_Gray_Sweep_Drop): Test for intersections which
4452	degenerate to a single point can be ignored; this has been confirmed
4453	by Greg Hitchcock from Microsoft.  (This was commented out code.)
4454
44552008-06-26  Werner Lemberg  <wl@gnu.org>
4456
4457	Improve navigation in API reference.
4458

4474	* src/tools/docmaker/tohtml.py (make_html_para): Implement it.
4475	Update header files accordingly.
4476
44772008-06-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4478
4479	* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
4480	and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
4481	bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
4482	ResourceIndex type definition.  The macro does not inform the type
4483	availability.
4484	* src/base/ftmac.c: More parentheses are inserted to clarify the
4485	conditionals to disable legacy APIs in `10.5 and later' cases.  If
4486	HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
4487
44882008-06-24  Werner Lemberg  <wl@gnu.org>
4489
4490	* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
4491	mode.
4492
4493	* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
4494	Draw_Sweep): No-dropout mode is value 2, not value 0.
4495	(Draw_Sweep): Really skip dropout handling for no-dropout mode.
4496
44972008-06-24  Werner Lemberg  <wl@gnu.org>
4498
4499	* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
4500	if it consists of one point only.  Based on a patch from Savannah
4501	bug #23683 (from John Tytgat).
4502
45032008-06-22  Werner Lemberg  <wl@gnu.org>
4504
4505	* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
4506	with IS_HINTED.
4507
4508	* docs/CHANGES: Updated.
4509
45102008-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4511
4512	* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
4513	but LDFLAGS does not, import it to LDFLAGS.  The option is used to
4514	specify non-default SDK on Mac OS X (e.g., universal binary SDK for
4515	Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
4516	recommends to add the option only to CFLAGS, LDFLAGS should include
4517	it because libfreetype.la is built with -no-undefined.  This fixes a
4518	bug reported by Ryan Schmidt in MacPorts,
4519	http://trac.macports.org/ticket/15331.
4520
45212008-06-21  Werner Lemberg  <wl@gnu.org>
4522
4523	Enable access to the various dropout rules of the B&W rasterizer.
4524	Pass dropout rules from the TT bytecode interpreter to the
4525	rasterizer.
4526
4527	* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
4528	FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
4529
4530	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
4531	Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
4532	OpenType specification.
4533	Fix mode 4 computation.
4534	(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
4535
4536	* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
4537	mode to FT_OUTLINE_XXX flags.
4538
4539	* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
4540
45412008-06-19  Werner Lemberg  <wl@gnu.org>
4542
4543	* src/cff/cffobjs.c (cff_face_init): Compute final
4544	`dict->units_per_em' value before assigning it to
4545	`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
4546	scaled incorrectly if the font matrix is non-standard.  This fixes
4547	Savannah bug #23630.
4548
4549	* docs/CHANGES: Updated.
4550
45512008-06-19  Werner Lemberg  <wl@gnu.org>
4552
4553	* src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix

4560
4561	* docs/CHANGES: Updated.
4562
45632008-06-15  George Williams  <gww@silcom.com>
4564
4565	* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
4566	`valid->extra2' to 1.  This is undocumented in the OpenType 1.5
4567	specification.
4568
45692008-06-15  Werner Lemberg  <wl@gnu.org>
4570
4571	* src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly

4575
45762008-06-10  Werner Lemberg  <wl@gnu.org>

4614	`clazz->done_face'.
4615
46162008-06-09  VaDiM  <s_sliva@rambler.ru>
4617
4618	Support debugging on WinCE.  From Savannah patch #6536; this fixes
4619	bug #23497.
4620
4621	* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
4622	as a replacement for OutputDebugStringA (which WinCE doesn't have).
4623	Update all callers.
4624	(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
4625	environment variables.
4626
46272008-06-09  Werner Lemberg  <wl@gnu.org>
4628
4629	* README.CVS: Updated.

4635
4636	* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
4637	`private_len' unsigned.
4638
4639	* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read

4650
4651
4652	* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
4653
4654
4655	* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
4656	`last_point'.
4657
4658
4659	* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
4660	`maxTwilightPoints'.
4661
46622008-06-06  Werner Lemberg  <wl@gnu.org>
4663
4664	* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
4665	correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
4666
46672008-06-03  Werner Lemberg  <wl@gnu.org>
4668
4669	* include/freetype/ftcache.h (FTC_FaceID): Change type back to
4670	FT_Pointer.  Reported by Ian Britten <britten@caris.com>.
4671
46722008-06-02  Werner Lemberg  <wl@gnu.org>
4673
4674	Emit header info for defined FreeType objects in reference.
4675
4676	* src/tools/docmaker/content.py (re_header_macro): New regexp.
4677	(ContentProcessor::__init__): Initialize new dictionary `headers'.
4678	(DocBlock::__init__): Collect macro header definitions.
4679
4680	* src/tools/docmaker/tohtml.py (header_location_header,
4681	header_location_footer): New strings.
4682	(HtmlFormatter::__init__): Pass `headers' dictionary.
4683	(HtmlFormatter::print_html_field): Don't emit paragraph tags.

4691
46922008-05-28  Werner Lemberg  <wl@gnu.org>
4693
4694	* src/tools/docmaker/sources.py (SourceBlock::__init__): While
4695	looking for markup tags, return immediately as soon a single one is
4696	found.
4697
46982008-05-28  Werner Lemberg  <wl@gnu.org>
4699
4700	* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
4701	original, unscaled input values.  Confirmed by Greg Hitchcock from
4702	Microsoft.
4703

4705
4706	* src/tools/docmaker/tohtml.py (block_footer_start,
4707	block_footer_middle): Beautify output.
4708
47092008-05-25  Werner Lemberg  <wl@gnu.org>
4710
4711	* src/raster/ftraster.c (fc_black_render): Return 0 when we are
4712	trying to render into a zero-width/height bitmap, not an error code.
4713
4714	* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
4715	of the graphics state for subglyphs to...
4716	(TT_Hint_Glyph): This function.
4717	Hinting instructions for a composite glyph apparently refer to the
4718	just hinted subglyphs, not the unhinted, unscaled outline.  This
4719	seems to fix Savannah bugs #20973 and (at least partially) #23310.
4720
47212008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4722
4723	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

4725	proposed by an anonymous reporter of Savannah bug #23204.
4726
47272008-05-18  Werner Lemberg  <wl@gnu.org>
4728
4729	* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
4730	correction for pixel boundary.  Without this patch, the effect can
4731	be cumulative under certain circumstances, making glyphs taller and
4732	taller after each call.  This fixes Savannah bug #19976.
4733
47342008-05-18  Werner Lemberg  <wl@gnu.org>
4735
4736	* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

4746	declarations non-global.
4747
4748	* src/type1/t1load.c: Add missing comment.
4749
47502008-05-17  Sam Hocevar  <samh>
4751

4765	ft_wgl_extra_glyph_name_offsets): New arrays.
4766	(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
4767	(ps_unicodes_init): Use them to add additional Unicode mappings.

4770
4771	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
4772	<op_closepath>: `closepath' without a path is a no-op, not an error
4773	(cf. the PS reference manual).

47812008-05-15  Werner Lemberg  <wl@gnu.org>
4782
4783	* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
4784	which contains a single but empty entry.  This is technically
4785	invalid (since it must end with `return'), but...
4786

47892008-05-14  Werner Lemberg  <wl@gnu.org>
4790
4791	Finish fix of scaling bug of CID-keyed CFF subfonts.
4792
4793	* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
4794	(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
4795	functions.
4796
4797	* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
4798	provide global hinting data for both the top-font and all subfonts
4799	(with proper scaling).
4800
4801	* src/cff/cffobjs.c (cff_make_private_dict): New function, using
4802	code from `cff_size_init'.
4803	(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
4804	Use CFF_Internal and handle subfonts.
4805	(cff_face_init): Handle top-dict and subfont matrices correctly;
4806	apply some heuristic in case of unlikely matrix concatenation
4807	results.  This has been discussed with people from Adobe (thanks
4808	goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
4809	and not correct.
4810
4811	* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
4812
4813	* src/cff/cffgload.c (cff_builder_init): Updated.
4814	(cff_decoder_prepare): Handle hints globals for subfonts.
4815	Update all callers.
4816	(cff_slot_load): Handling scaling of subfonts properly.
4817
4818	* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
4819	(cff_parse_font_matrix): Use it.
4820
4821	* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
4822	FT_ULong.
4823
4824	* docs/CHANGES: Document it.
4825
48262008-05-13  Werner Lemberg  <wl@gnu.org>
4827
4828	* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
4829	Handle case `face_index < 0'.
4830	* docs/CHANGES: Document it.
4831
48322008-05-04  Werner Lemberg  <wl@gnu.org>
4833
4834	First steps to fix the scaling bug of CID-keyed CFF subfonts,
4835	reported by Ding Li on 2008/03/28 on freetype-devel.
4836
4837	* src/base/cff/cffparse.c (power_tens): New array.
4838	(cff_parse_real): Rewritten to introduce a fourth parameter which
4839	returns the `scaling' of the real number so that we have no
4840	precision loss.  This is not used yet.
4841	Update all callers.
4842	(cff_parse_fixed_thousand): Replace with...
4843	(cff_parse_fixed_scaled): This function.  Update all callers.
4844
48452008-05-03  Werner Lemberg  <wl@gnu.org>
4846
4847	* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
4848	transformation since it recursively calls FT_Load_Glyph.  This fixes
4849	Savannah bug #23143.
4850
48512008-04-26  Werner Lemberg  <wl@gnu.org>
4852
4853	* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'
4854	and `scale_y' as obsolete since they aren't used.
4855	* src/psaux/psobjs.c (t1_builder_init): Updated.
4856
4857	* src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as
4858	obsolete since they aren't used.
4859	* src/cff/cffgload.c (cff_builder_init): Updated.
4860
48612008-04-14  Werner Lemberg  <wl@gnu.org>
4862
4863	* src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to
4864	`FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZ'.  From Savannah
4865	bug #22909.
4866
48672008-04-13  Werner Lemberg  <wl@gnu.org>
4868
4869	* src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
4870	integer part is zero.
4871
48722008-04-01  Werner Lemberg  <wl@gnu.org>
4873
4874	Fix compilation with g++ 4.1 (with both `single' and `multi'
4875	targets).
4876
4877	* src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
4878	which is crossed by a `goto'.
4879
4880	* src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
4881
48822008-03-31  Werner Lemberg  <wl@gnu.org>
4883
4884	Fix support for subsetted CID-keyed CFFs.
4885
4886	* include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
4887	FT_IS_CID_KEYED): New macros.
4888
4889	* src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
4890	maximum CID value in CID-keyed CFFs.
4891	Handle FT_FACE_FLAG_CID_KEYED flag.
4892
4893	* docs/CHANGES: Document it.
4894
4895
4896	Fix CFF font matrix calculation and improve precision.
4897
4898	* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
4899	part is zero.
4900	(cff_parse_font_matrix): Simplify computation of `units_per_em';
4901	this prevents overflow also.
4902
4903
4904	Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
4905
4906	* src/cid/cidriver.c: Include FT_SERVICE_CID_H.
4907	(cid_get_ros): New function.
4908	(cid_service_cid_info): New service structure.
4909	(cid_services): Register it.
4910
49112008-03-23  Werner Lemberg  <wl@gnu.org>
4912
4913	Adjustments for Visual C++ 8.0, as reported by Rainer Deyke.
4914
4915	* builds/compiler/visualc.mk (CFLAGS): Remove /W5.
4916	(ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
4917
49182008-03-21  Laurence Darby  <ldarby>
4919
4920	* src/type1/t1objs.c (T1_Face_Init): Use `/Weight'.  Patch from
4921	Savannah bug #22675.
4922
49232008-03-13  Derek Clegg  <dclegg@apple.com>
4924
4925	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.
4926	Patch from Savannah bug #22541.
4927
49282008-03-03  Masatoshi Kimura  <VYV03354@nifty.ne.jp>
4929
4930	* src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
4931	tt_cmap14_find_variant): Return correct value.
4932	(tt_cmap14_variant_chars): Fix check for `di'.
4933
49342008-02-29  Wermer Lemberg  <wl@gnu.org>
4935
4936	* docs/CHANGES: Updated.
4937
49382008-02-29  Wolf
4939
4940	Add build support for symbian platform.  From Savannah bug #22440.
4941
4942	* builds/symbian/*: New files.
4943
49442008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4945
4946	* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
4947	synthesis.  For any face of a specified FOND, always the name for
4948	the first face was used.  Except of a FOND that refers multiple
4949	Type1 font files, wrong synthesized font names are not used at all,
4950	so this is an invisible bug.  A few limit checks are added too.
4951
4952	* builds/mac/ftmac.c: Ditto.
4953
49542008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4955
4956	* builds/unix/configure.raw: Split compiler option to link Carbon
4957	frameworks to one option for CoreServices framework and another
4958	option for ApplicationServices framework.  The split options can be
4959	managed by GNU libtool to avoid unrequired duplication when FreeType
4960	is linked with other applications.  Suggested by Daniel Macks,
4961	Savannah bug #22366.
4962
49632008-02-18  Victor Stinner  <victor.stinner@haypocalc.com>
4964
4965	* src/truetype/ttinterp.c (Ins_IUP): Check number of points.  Fix
4966	from Savannah bug #22356.
4967
49682008-02-17  Jonathan Blow  <jon@number-none.com>
4969
4970	* src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
4971	Check for valid callback pointers.
4972
49732008-02-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4974
4975	* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
4976	handle by its value instead of ResError(), fix provided by Deron
4977	Kazmaier.  According to the Resource Manager Reference,
4978	GetResource(), Get1Resource(), GetNamedResource(),
4979	Get1NamedResource() and RGetResource() set noErr but return NULL
4980	handle when they can not find the requested resource.  These
4981	functions never return undefined values, so it is sufficient to
4982	check if the handle is not NULL.
4983
4984	* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
4985
49862008-02-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4987
4988	* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
4989	inclusion styles.  Now it always includes src/base/ftmac.c;
4990	builds/mac/ftmac.c is never included in any configuration.
4991
4992	* builds/unix/configure.raw: Print warning if configure is executed
4993	with options to specify Carbon functionalities explicitly.
4994
4995	* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
4996	included automatically and manual replacement is required.
4997
49982008-02-11  Werner Lemberg  <wl@gnu.org>
4999
5000	* builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
5001	(dos_setup), builds/freetype.mk (clean_project_dos,
5002	distclean_project_dos): Don't use \ but $(SEP).  Reported by Duncan
5003	Murdoch.
5004
50052008-01-18  Sylvain Pasche  <sylvain.pasche@gmail.com>
5006
5007	* src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to
5008	mention intra-pixel algorithm.
5009
5010	* include/freetype/freetype.h (FT_Render_Mode): Mention that
5011	FT_Library_SetLcdFilter can be used to reduce fringes.
5012
50132008-01-16  Werner Lemberg  <wl@gnu.org>
5014
5015	* src/raster/ftraster.c (ft_black_render): Check `outline' before
5016	using it.  Reported by Allan Yang.
5017
50182008-01-12  Werner Lemberg  <wl@gnu.org>
5019
5020	* src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove.
5021
50222008-01-12  Allan Yang, Jian Hua - SH  <Allan.Yang@fmc.fujitsu.com>
5023
5024	* src/raster/ftraster.c (ft_black_init)
5025	[FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.
5026
50272008-01-10  Werner Lemberg  <wl@gnu.org>
5028
5029	* src/truetype/ttgload.c (load_truetype_glyph): Handle the case
5030	where the number of contours in a simple glyph is zero (and which
5031	does contain an entry in the `glyf' table).  This fixes Savannah bug
5032	#21990.
5033
50342008-01-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5035
5036	Formatting suggested by Sean McBride.
5037
5038	* builds/mac/ftmac.c: Formatting (tab expanded).
5039	* src/autofit/afindic.c: Ditto.
5040	* src/base/ftcid.c: Ditto.
5041	* src/base/ftmac.c: Ditto.
5042
50432007-12-30  Werner Lemberg  <wl@gnu.org>
5044
5045	* src/smooth/ftgrays.c (gray_raster_render): Check `outline'
5046	correctly.
5047
50482007-12-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5049
5050	Improvement of POSIX resource-fork accessor to load unsorted
5051	references in a resource.  In HelveLTMM (resource-fork PostScript
5052	Type1 font bundled with Mac OS X since 10.3.x), the appearance order
5053	of PFB chunks is not sorted; sorting the chunks by reference IDs is
5054	required.
5055
5056	* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
5057	type to store a pair of reference ID and offset to the chunk.
5058
5059	* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
5060	sort FT_RFork_Ref by their reference IDs.
5061
5062	(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
5063	sorted by reference ID.
5064
50652007-12-14  Werner Lemberg  <wl@gnu.org>
5066
5067	* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
5068	division too early; otherwise the most significant digit(s) of the
5069	final result are lost as the value is truncated to an integer.  This
5070	fixes Savannah bug #21794 (where the patch has been posted too).
5071
50722007-12-06  Fix  <4d876b82@gmail.com>
5073
5074	Pass options from one configure script to another as-is (not
5075	expanded).  This is needed for options like
5076	--includedir='${prefix}/include'.
5077
5078	* builds/unix/detect.mk, configure: Prevent argument expansion in
5079	call to the (real) `configure' script.
5080
50812007-12-06  Werner Lemberg  <wl@gnu.org>
5082
5083	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
5084	TT_USE_BYTECODE_INTERPRETER isn't defined.
5085
50862007-12-06  Werner Lemberg  <wl@gnu.org>
5087
5088	There exist CFFs which contain opcodes for the Type 1 operators
5089	`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
5090	However, it doesn't harm to support them.
5091
5092	* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
5093	`cff_op_closepath.'
5094	(cff_argument_counts): Ditto.
5095
5096	(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
5097	and 13 (hsbw) which are invalid in Type 2 charstrings.
5098
50992007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5100
5101	* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
5102	support new pathname syntax `..namedfork/rsrc' to access a resource
5103	fork on Mac OS X.  The legacy syntax `/rsrc' does not work on
5104	case-sensitive HFS+.
5105	(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
5106	buffer size to store a pathname.
5107	* include/freetype/internal/ftrfork.h: Increment the number of
5108	resource fork guessing rule.
5109
51102007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5111
5112	* builds/unix/configure.raw: Improve the compile tests to search
5113	Carbon functions.
5114	* builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
5115	proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).
5116
51172007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5118
5119	The documents and comments for Mac OS X are improved by Sean
5120	McBride.
5121
5122	* src/base/ftmac.c: Fix a comment.
5123	* include/freetype/ftmac.h: Ditto.
5124	* docs/INSTALL.MAC: Improve English and add comment on lowest
5125	system version specified by MACOSX_DEPLOYMENT_TARGET.
5126
51272007-12-04  Werner Lemberg  <wl@gnu.org>
5128
5129	* src/cff/cffload.c (cff_subfont_load): Don't use logical OR to
5130	concatenate error codes.
5131	* src/sfnt/ttsbit.c (Load_SBit_Range): Ditto.
5132
51332007-12-04  Graham Asher  <graham.asher@btinternet.com>
5134
5135	* src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
5136	concatenate error codes.
5137
51382007-12-04  Sean McBride  <sean@rogue-research.com>
5139
5140	* src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler
5141	warning.
5142
51432007-11-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5144
5145	Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
5146	not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
5147	cannot mmap() the specified file and cannot seek to head of the
5148	specified file, it returns NULL stream and FT_Open_New() returns the
5149	error immediately.  On MacOS, most legacy MacOS fonts fall into such
5150	a scenario because their data forks are zero-sized and cannot be
5151	sought.  To proceed to guessing of resource fork fonts, the
5152	functions for legacy MacOS font must properly handle the NULL stream
5153	returned by FT_New_Stream().
5154
5155	* src/base/ftobjs.c (IsMacBinary): Return error
5156	FT_Err_Invalid_Stream_Operation immediately when NULL stream is
5157	passed.
5158	(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
5159	to fallback.  Originally, legacy MacOS font is tested in the cases
5160	of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
5161	or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
5162	.dfont header is combined).  Now the case of
5163	FT_Err_Cannot_Open_Stream is included.
5164
5165	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
5166	skip FT_Stream_Seek(), which seeks to the head of stream, and
5167	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
5168	for a NULL stream causes a Bus error on Mac OS X.
5169	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
5170	immediately if passed stream is NULL.
5171	(raccess_guess_apple_single): Ditto.
5172
51732007-11-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
5174
5175	Fix for Carbon incompatibilities since Mac OS X 10.5,
5176	proposed by Sean McBride.
5177
5178	* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
5179
5180	* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
5181	FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling
5182	Carbon functions from a forked process is classified as unsafe
5183	by Apple.  All Carbon-dependent functions should be deprecated.
5184
5185	* src/base/ftmac.c: Use essential header files
5186	<CoreServices/CoreServices.h> and
5187	<ApplicationServices/ApplicationServices.h> instead of
5188	all-in-one header file <Carbon/Carbon.h>.
5189
5190	Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
5191	genuine macro PATH_MAX.
5192
5193	Add fallback macro for kATSOptionFlagsUnRestrictedScope which
5194	is not found in Mac OS X 10.0.
5195
5196	Multi-character constants ('POST', 'sfnt' etc) are replaced by
5197	64bit constants calculated by FT_MAKE_TAG() macro.
5198
5199	For the index in the segment of resource fork, new portable
5200	type ResourceIndex is introduced for better compatibility.
5201	This type is since Mac OS X 10.5, so it is defined as short
5202	when built on older platforms.
5203
5204	(FT_ATSFontGetFileReference): If build target is only the systems
5205	10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
5206
5207	(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
5208	and newer or 64bit platform, because legacy type FSSpec type is
5209	removed completely.
5210
5211	(FT_New_Face_From_FSSpec): Ditto.
5212
52132007-11-01  Werner Lemberg  <wl@gnu.org>
5214
5215	* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This
5216	fixes Savannah bug #21485.
5217
52182007-10-29  Daniel Svoboda  <dasvo@planeta@cz>
5219
5220	* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver

6115
6116	* src/base/ftobjs.c (FT_Set_Char_Size): As suggested by James Cloos,

6121
6122	Add special code to detect `extra-light' fonts and do not snap their
6123	stem widths too much to avoid bizarre hinting effects.
6124

6126	`extra_light' members.

6141	gracefully.
6142	(_bdf_set_default_spacing): Increase `name' buffer size to 256 and
6143	issue an error for longer names.  This fixes CVE-2007-1351.

6159
6160	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
6161	computations in order to ignore single-point contours.  These are
6162	never rasterized and correspond in certain fonts to mark-attach
6163	points that are very far from the glyph's real outline, ruining the
6164	computation.
6165
6166	* src/autofit/afloader.c (af_loader_load_g): In the case of
6167	monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0.
6168	Otherwise code that uses them will most certainly ruin the fixed
6169	advance property.

6199
6200	* builds/unix/configure.raw: Dequote `OS_INLINE' in comment of
6201	conftest.c, to avoid unexpected shell evaluation.  Possibly it is a
6202	bug or undocumented behaviour of autoconf.

6205
6206	* src/truetype/ttinterp.c (Ins_MDRP): Another bytecode regression

6259	* src/truetype/ttobs.c (tt_size_init_bytecode): Clear the `x_ppem'
6260	and `y_ppem' fields of the `TT_Size.metrics' structure, not those of
6261	`TT_Size.root.metrics'.  Problem reported by Daniel Glöckner
6262	<daniel-gl@gmx.net>.
6263
6264	* src/type1/t1afm.c (T1_Read_PFM): Read kerning values as 16-bit
6265	signed values, not unsigned ones.  Problem reported by Johannes
6266	Walther <joh_walt@yahoo.de>.

6378

6439	s/2.3.0/2.3.1/.
6440
6441	* builds/unix/configure.raw (version_info): Set to 9:12:3.
6442
6443
6444	* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
6445	(af_loader_load_g): Disable the warper (i.e., the light hinting
6446	improvements) to make a 2.3.1 bugfix release before introducing a
6447	new feature.  This should give us more time to tune and improve the
6448	warper for the next release.
6449
6450	* docs/CHANGES: Update accordingly.
6451
64522007-01-25  David Turner  <david@freetype.org>
6453
6454	For light auto-hinting, improve glyph advance widths and resurrect
6455	normal/full hinting to its normal quality.
6456
6457	* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
6458	and `xmax_delta'.
6459	* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
6460	and `xmax_delta'.
6461
6462	* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
6463	preprocessor conditional with if-clause, handling both light and
6464	normal mode.
6465
6466	* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
6467	(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.
6468
64692007-01-25  Werner Lemberg  <wl@gnu.org>
6470

6482
64832007-01-25  Werner Lemberg  <wl@gnu.org>
6484
6485	* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
6486	correctly in a sanity check.  Since this function is only used to
6487	load local and global functions, any charstring that called the last
6488	local/global function would fail otherwise.  This fixes Savannah bug
6489	#18867.
6490
6491	* docs/CHANGES: Document it.
6492
64932007-01-23  David Turner  <david@freetype.org>

6496	prevented compilation when disabling both the unpatented and the
6497	bytecode interpreter in the TrueType font driver.
6498
6499
6500	Fix and enable the warper to improve `light' hinting mode.  This is

6610
6611	* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.

6614
6615	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
6616	bug in the bitmap emboldener if the pitch of the source bitmap is

6644	Yamato.
6645
6646	* autogen.sh: Small fix to get it working on Mac OS X properly:
6647	The issue is that GNU libtool is called `glibtool' on this platform,
6648	and we must call `glibtoolize', since `libtoolize' doesn't exist.
6649
66502007-01-10  David Turner  <david@freetype.org>

6677
6678	* include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add

6680	corresponding to a given character pixel size.
6681
6682	* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the

6684	versions.
6685
6686	* include/freetype/config/ftheader.h (FT_GASP_H): New macro for
6687	<freetype/ftgasp.h>.

6692	default build.
6693
66942007-01-07  Werner Lemberg  <wl@gnu.org>
6695
6696	* src/cid/cidparse.c (cid_parser_new): Improve error message for

6701
6702	* src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts.

6706	* src/cff/cffload.c (cff_index_init): Remove unused variable.
6707	(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.
6708
67092007-01-04  David Turner  <david@freetype.org>
6710
6711	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
6712	correctly.  This fixes Savannah bug #17876.
6713
6714
6715	Do not allocate interpreter-specific tables in memory if we are not
6716	going to load glyphs with the bytecode interpreter anyway.
6717
6718	* src/truetype/ttgload.c (tt_loader_init): Load execution context
6719	only if glyph is hinted.
6720	Updated.
6721	* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
6722	and `cvs_ready'.
6723	Add `tt_size_ready_bytecode' declaration.
6724	* src/truetype/ttobjs.c (tt_size_done_bytecode,
6725	tt_size_init_bytecode, tt_size_ready_bytecode): New functions.

6727	(tt_size_done): Move most code into `tt_size_done_bytecode'.
6728	(tt_size_reset): Move some code to `tt_size_ready_bytecode'.
6729
6730
6731	Don't extract the metrics table from the SFNT font file.  Instead,
6732	reparse it on each glyph load.  The runtime difference is not
6733	noticeable, and it can save a lot of heap memory when memory-mapped
6734	files are not used.
6735
6736	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
6737	`horz_metrics_offset' and `vert_metrics_ofset'.
6738	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
6739	Updated.
6740
6741
6742	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
6743
6744
6745	Do not load the CFF index offsets into memory, since this wastes a
6746	*lot* of heap memory with large Asian CFF fonts.  There is no
6747	significant performance loss.
6748
6749	* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
6750	* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
6751	`data_size'.
6752	(CFF_CharsetRec): Add field `num_glyphs'.
6753
6754	* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
6755	cff_charset_cid_to_gindex): New functions.
6756	(cff_new_index): Renamed to...
6757	(cff_index_init): This.  Update all callers.
6758	Updated -- some code has been moved to `cff_index_load_offsets'.
6759	(cff_done_index): Renamed to...
6760	(cff_index_done): This.  Update all callers.
6761	(cff_index_get_pointers, cff_index_access_element): Updated to use
6762	stream offsets.
6763	(cff_charset_compute_cids): Set `num_glyphs' field.
6764	(cff_encoding_load): Updated.
6765
6766	* src/cff/cffgload.c (cff_slot_load): Updated.
6767

6771	autogen.sh and pointer to README.CVS.
6772
6773	* README.CVS: Add common problem description and solution
6774	when running autogen.sh.
6775
6776	* docs/INSTALL: Add reference to MacOS X.
6777
6778	* docs/MAKEPP, docs/INSTALL.MAC: New documentation files.
6779
6780	* docs/TODO: Remove obsolete items.
6781
6782	* src/raster/ftraster.c: (TRaster_Instance): Replace it with...
6783	(TWorker): This.
6784	Remove `count_table' and `memory'.
6785	Make `grays' a pointer.
6786	(TRaster): New structure.
6787	(count_table): New static array.
6788	(RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
6789	Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
6790	ft_black_set_mode, ft_black_render): Updated.
6791	(ft_black_init): Don't initialize `count_table'.
6792	(ft_black_reset): Use the render pool.  This saves about 6KB of
6793	heap space for each FT_Library instance.
6794
6795	* src/smooth/ftgrays.c (TRaster): Replaced with...
6796	(TWorker): This.
6797	Remove `memory'.
6798	(TRaster): New structure.
6799
6800	(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
6801	gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
6802	gray_render_span, gray_raster_render): Updated.
6803	(gray_raster_reset): Use the render pool.  This saves about 6KB of
6804	heap space for each FT_Library instance.
6805
6806	* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
6807	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
6808	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
6809	FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
6810	the optimization is no longer experimental.
6811
6812	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
6813	Remove a typo that results in no hinting and a memory leak with some
6814	large Asian CFF fonts.
6815
6816	* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
6817	which happens when FT_Done_Library is called with still opened
6818	CFF_Faces in it.  We need to close all faces before destroying the
6819	modules, or else some bad things (memory leaks) may happen.
6820
68212007-01-02  Werner Lemberg  <wl@gnu.org>
6822
6823	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):

6833	function.
6834	Check uniqueness of the gid pairs.
6835	(gxv_kern_subtable_fmt0_validate): Move some code to
6836	`gxv_kern_subtable_fmt0_pairs_validate'.
6837
68382006-12-22  David Turner  <david@freetype.org>
6839
6840	* src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
6841	warnings.
6842

6860	* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
6861	* builds/unix/configure.raw: Ditto.  When explicit switches for
6862	FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
6863	builds/mac/ftmac.c is used instead of default src/base/ftmac.c.
6864
68652006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
6866
6867	* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.

6873	that cannot be built at present.
6874
68752006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
6876
6877	* src/base/ftobjs.c: Improvement of resource fork handler for
6878	POSIX, cf.
6879	  http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
6880	(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
6881	format or .dfont, to simulate the face index number counted by ftmac.c.

6883
68842006-12-10  Werner Lemberg  <wl@gnu.org>
6885

6889
6890	* builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'

6907
6908	* src/autofit/afloader.c (af_loader_load_g): Small adjustment
6909	to the spacing of auto-fitted glyphs.  This only impacts rare

6911
69122006-12-03  Werner Lemberg  <wl@gnu.org>
6913
6914	* src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.

69322006-11-28  David Turner  <david@freetype.org>
6933
6934	* src/smooth/ftgrays.c (gray_raster_render): Return 0 when we are
6935	trying to render into a zero-width/height bitmap, not an error code.
6936
6937	* src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.
6938
6939	* src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType

6950
6951	* src/autofit/afhints.c	(af_glyph_hints_dump_points,
6952	af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
6953	Add stubs to link the `ftgrid' test program when debugging is
6954	disabled in the auto-hinter.
6955
69562006-11-23  David Turner  <david@freetype.org>
6957
6958	* src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,

6974
69752006-11-22  Werner Lemberg  <wl@gnu.org>
6976
6977	Fix Savannah bug #15553.
6978
6979	* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
6980	program after a change from mono to grayscaling (and vice versa).
6981	Use correct constant for comparison to get `exec->grayscale'.
6982
69832006-11-18  Werner Lemberg  <wl@gnu.org>
6984
6985	Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
6986	test for a valid glyph index must be deferred to the font drivers.
6987	This patch fixes Savannah bug #18301.
6988
6989	* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
6990	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
6991	(cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),

69972006-11-13  David Turner  <david@freetype.org>
6998
6999	* src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
7000	`enhancements' are still too buggy for general use.
7001
7002	* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
7003	FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros
7004	when building the library to change the default LCD filter to be
7005	used.  This is only useful for experimentation.
7006
7007	* include/freetype/ftlcdfil.h: Update documentation.
7008
70092006-11-10  David Turner  <david@freetype.org>
7010
7011	* src/smooth/ftsmooth.c: API change for the LCD
7012	filter.  The FT_LcdFilter value is an enumeration describing which
7013	filter to apply, with new values FT_LCD_FILTER_LIGHT and
7014	FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
7015	algorithm which produces strong color fringes for everything
7016	except very-well hinted text).
7017
7018	* include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
7019	second parameter to an enum type.
7020
7021	* src/base/ftlcdfil.c (USE_LEGACY): Define.

7032	callback and update other fields.
7033
7034	* src/smooth/ftsmooth.c (ft_smooth_render_generic)
7035	[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
7036	Other minor improvements.
7037
7038	* src/autofit/aflatin.c: Various tiny improvements that drastically
7039	improve the handling of serif fonts and of LCD/LCD_V hinting modes.
7040	(af_latin_hints_compute_edges): Fix typo.
7041	(af_latin_compute_stem_width): Take better care of diagonal stems.

7050	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
7051	also.
7052
70532006-11-03  Werner Lemberg  <wl@gnu.org>
7054
7055	* src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

7058
7059	Add a few tweaks to better handle serif fonts.
7060	Add more debugging messages.
7061
7062	* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
7063	segments that are less than 1.5 pixels high.  This gets rid of
7064	*many* corner cases with serifs.
7065	(af_latin_align_linked_edge): Add logging message.
7066	(af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
7067	Add logging messages.
7068	Handle AF_EDGE_FLAG flag specially.
7069
7070	* src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
7071	_af_debug_disable_blue_hints, and _af_debug_hints variables.
7072
7073	* src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
7074	Update external declarations.
7075	(af_corner_orientation, af_corner_is_flat): Replaced by...
7076
7077	* include/freetype/internal/ftcalc.h (ft_corner_orientation,
7078	ft_corner_is_flat): These declarations.
7079
7080	* src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
7081	Comment out.  Replaced by...
7082
7083	* src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
7084	These functions.  Update all callers.
7085	(FT_Add64) [!FT_LONG64]: Simplify.
7086
7087	* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
7088	(af_direction_compute): Add a missing FT_ABS call.  This bug caused
7089	production of garbage by missing lots of segments.
7090
7091	* src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.
7092
7093	* src/autofit/afloader.c (af_loader_init, af_loader_done)

7109	as argument.
7110
71112006-10-23  Zhe Su  <zsu@novell.com>
7112
7113	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
7114	better deal with broken Asian fonts with strange glyphs, having
7115	self-intersections and other peculiarities.  The used algorithm is
7116	based on the nonzero winding rule.
7117
71182006-10-23  David Turner  <david@freetype.org>
7119
7120	Speed up the CFF font loader.  With some large CFF fonts,
7121	FT_Open_Face is now more than three times faster.
7122
7123	* src/cff/cffload.c (cff_get_offset): Removed.
7124	(cff_new_index): Inline functionality of `cff_get_offset'.

7130	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX
7131	with FT_NEXT_XXX.
7132
7133
7134	Speed up the Postscript hinter, with more than 100% speed increase
7135	on my machine.
7136
7137	* src/pshinter/pshalgo.c (psh_corner_is_flat,
7138	psh_corner_orientation): New functions.
7139	(psh_glyph_compute_inflections): Merge loops for efficiency.
7140	Use `psh_corner_orientation'.
7141	(psh_glyph_init): Use `psh_corner_is_flat'.
7142	(psh_hint_table_find_strong_point): Renamed to...
7143	(psh_hint_table_find_strong_points): This.
7144	Rewrite, adding argument to handle all points at once.
7145	Update all callers.
7146	(PSH_MAX_STRONG_INTERNAL): New macro.
7147	(psh_glyph_interpolate_normal_points): Rewrite for efficiency.

7155
7156	* docs/INSTALL.CROSS: New document file for cross-building.
7157
7158	* builds/unix/configure.raw: Preliminary cross-building support.

7161	Also suffix for target executable is passed by EXEEXT.
7162
7163	* builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
7164	build `apinames' which runs on building system.  They are set by
7165	CC_BUILD and EXEEXT_BUILD.
7166
7167	* builds/exports.mk (APINAMES_EXE): Change the extension for
7168	apinames from the suffix for target (E) to that for building host
7169	(E_BUILD).
7170

7196
7197	* include/freetype/internal/ftvalid.h: Add comment that
7198	ft_validator_run must not be used.

7242
7243	* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.
7244
7245
7246	Add a new API to support color filtering of subpixel glyph bitmaps.
7247	In a default build, the function `FT_Library_SetLcdFilter' returns
7248	`FT_Err_Unimplemented_Feature'; you need to #define
7249	FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
7250	real implementation.
7251
7252	* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.
7253
7254	* include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
7255	typedef.
7256	(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
7257	`lcd_filter_weights' and `lcd_filter'.
7258
7259	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
7260	`hmul' and `vmul'.
7261
7262	Handle subpixel rendering.
7263	Simplify function.
7264	(ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
7265	(ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.
7266
7267	* include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
7268	pointing to <freetype/ftlcdfil.h>.
7269
7270	* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
7271	vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.
7272
7273	* modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.
7274
72752006-09-26  David Bustin
7276
7277	* src/pfr/pfrobjs.c (pfr_face_get_kerning): Skip adjustment bytes

7279
72802006-09-26  David Turner  <david@freetype.org>
7281

7291
7292	* include/freetype/config/ftoption.h, devel/ftoption.h
7293	(FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
7294	we want to compile LCD-optimized rendering code (à la ClearType) or
7295	not.  The macro *must* be disabled in default builds of the library
7296	for patent reasons.
7297
7298	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
7299	LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
7300	isn't defined at compile time.  This only changes the content of the
7301	rendered glyph to match the one of normal gray-level rendering,
7302	hence clients should not need to be modified.
7303
7304	* docs/CHANGES: Updated.
7305
73062006-09-18  Garrick Meeker  <garrick@digitalanarchy.com>

7313	* src/sfnt/sfobjs.c (tt_face_get_name): Support some fonts which
7314	report their English names through an Apple Roman
7315	(platform,encoding) pair, with language_id != English.
7316
7317	If the font uses another name entry with language_id == English, it
7318	will be selected correctly, though.
7319
7320	* src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
7321	selection for `mingli.ttf'.
7322
73232006-09-05  Werner Lemberg  <wl@gnu.org>
7324
7325	* src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size'
7326	values which have the upper two bytes set to 0xFF instead of 0x00
7327	(as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
7328	`HAN NOM B.ttf').
7329
7330	* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.
7331
73322006-09-05  David Turner  <david@freetype.org>
7333

7335
7336	* src/smooth/ftgrays.c (GRAYS_COMPACT): Removed.

7340	(gray_record_cell): Simplify.
7341	(gray_set_cell): Rewrite.
7342	(gray_start_cell): Apply offsets to `ras.ex' and `ras.ey'.
7343	(gray_render_span): Don't use FT_MEM_SET for small values.
7344	(gray_dump_cells) [DEBUG_GRAYS]: New function.
7345	(gray_sweep): Avoid buffer overwrites when to drawing the end of a
7346	bitmap scanline.
7347	(gray_convert_glyph): Fix speed-up.
7348
73492006-09-04  David Turner  <david@freetype.org>
7350
7351	* src/smooth/ftgrays.c (gray_convert_glyphs): Make it work with
7352	64bit processors.
7353
73542006-09-03  Werner Lemberg  <wl@gnu.org>

77762006-06-08  Werner Lemberg  <wl@gnu.org>
7777
7778	* src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of
7779	errors.
7780
77812006-06-07  David Turner  <david@freetype.org>
7782
7783	* src/type1/t1afm.c (KERN_INDEX): Make it more robust.
7784	(T1_Read_Metrics): Fix memory leak which happened when the metrics
7785	file doesn't have kerning pairs.  This fixes Savannah bug #16768.
7786
77872006-06-06  David Turner  <david@freetype.org>
7788
7789	Fix memory leak described in Savannah bug #16759.
7790
7791	We change `ps_unicodes_init' so that it also takes a
7792	`free_glyph_name' callback to release the glyph names returned by
7793	`get_glyph_name'
7794
7795	* include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
7796	Renamed to ...
7797	(PS_GetGlyphNameFunc): This.
7798	(PS_FreeGlyphNameFunc): New typedef.
7799	(PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.
7800
7801	* src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
7802	argument.
7803	(cff_sid_free_glyph_name): New function.
7804	(cff_cmap_unicode_init): Updated.
7805
7806	* src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated.

7810
7811
78122006-06-04  David Turner  <david@freetype.org>
7813
7814	* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
7815	`item_size == 0' as well -- though this sounds weird, it can
7816	theoretically happen.  This fixes Savannah bug #16669.
7817
7818	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
7819	of `face->num_glyphs' which missed the last glyph, due to
7820	the offset-by-1 computation, since the PFR format doesn't
7821	guarantee that glyph index 0 corresponds to the `missing
7822	glyph.  This fixes Savannah bug #16668.
7823
78242006-05-25  Werner Lemberg  <wl@gnu.org>
7825
7826	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
7827	`-no-undefined'.  Reported by Christian Biesinger.
7828
78292006-05-19  Brian Weed  <bw@imaginengine.com>
7830
7831	* builds/win32/visualc/freetype.dsp: Release libraries no longer
7832	have debug information, and debug libraries use `C7 compatible'
7833	debug info.
7834
78352006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
7836
7837	Apply patch by Derek Clegg to fix two memory leaks in the MacOS
7838	resource fork handler.  This fixes Savannah bug #16631.
7839
7840	* src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
7841	`FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.
7842
7843	* src/base/ftrfrk.c (raccess_guess_linux_double_from_file_name):
7844	Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.
7845
78462006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
7847
7848	* build/unix/configure.raw: Add a fallback to disable Carbon
7849	dependency, if configured with no options on Mac OS X.
7850
78512006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
7852
7853	* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
7854	its content cannot be parsed as supported font.  This fixes
7855	the second part of Savannah bug #16590.
7856
78572006-05-18  Werner Lemberg  <wl@gnu.org>
7858
7859	* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
7860	[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
7861
78622006-05-17  David Turner  <david@freetype.org>
7863
7864	This is a major patch used to drastically improve the performance of
7865	loading glyphs.  This both speeds up loading the glyph vectors
7866	themselves and the auto-fitter module.
7867
7868	We now use inline assembler code with GCC to implement `FT_MulFix',
7869	which is probably the most important function related to the
7870	engine's performance.
7871
7872	The resulting speed-up is about 25%.
7873
7874
7875	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
7876	`cursor' and `limit'.
7877
7878	* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
7879	New functions.
7880	(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
7881	[TEST]: Remove.
7882
7883	* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
7884	code.
7885
7886	* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
7887	`FT_ZERO'
7888	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
7889	(af_glyph_hints_reload: Rewrite recognition of weak points.
7890
7891	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
7892	constant values out of the loops.
7893
7894	* src/autofit/aftypes.h: Updated.
7895
7896	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
7897
7898	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
7899	product to get orientation.
7900
7901	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
7902	(FT_Stream_OpenGzip): Use it to handle small files directly in
7903	memory.
7904
7905	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
7906	Improve performance.
7907
7908	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
7909	`limit'.
7910
7911	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
7912	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
7913	exceedingly large values of number of contours.  Speed up by
7914	reducing the number of loops.
7915
7916	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
7917
7918
7919	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
7920	used to detect rogue clients from 4 to 16.  This is to prevent some
7921	segmentation faults with fonts like `KozMinProVI-Regular.otf' which
7922	comes from the Japanese Adobe Reader Asian Font pack.
7923
79242007-05-17  Werner Lemberg  <wl@gnu.org>
7925
7926	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
7927	fixes the first part of Savannah bug #16590.
7928
79292006-05-16  Werner Lemberg  <wl@gnu.org>
7930
7931	* docs/PROBLEMS: Updated icl issues.
