118
119	Allow compilation again with C++ compilers.
120
121	* include/freetype/internal/ftmemory.h (FT_ASSIGNP,
122	FT_ASSIGNP_INNER): New macros which do the actual assignment, and
123	which exist in two variants (for C and C++).
124	Update callers accordingly.
125
1262006-05-03  Werner Lemberg  <wl@gnu.org>
127
128	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.
129
1302006-05-02  Werner Lemberg  <wl@gnu.org>
131
132	* include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++).
133	(FT_ALLOC): Remove redundant redefinition.
134
135	* builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use
136	`-Wstrict-prototypes'.
137
138	* src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.
139
140	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:
141	Remove `extern'.
142
1432006-05-02  David Turner  <david@freetype.org>
144
145	Update the memory management functions and macros to safely deal
146	with array size buffer overflows.  This corresponds to attempts to
147	allocate arrays that are too large.  For an example, consider the
148	following code:
149
150	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
151	  count ); for ( nn = 0; nn < count; nn++ )
152	    array[nn] = read_item_from_file();
153
154	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
155	multiplication overflows, and the array allocated os smaller than
156	the data read from the file.  In this case, the heap will be
157	trashed, and this can be used as a denial-of-service attack, or make
158	the engine crash later.
159
160	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
161	count is no larger than `FT_INT_MAX/item_size', otherwise a new
162	error code `FT_Err_Array_Too_Large' will be returned.
163
164	Note that the memory debugger now works again when FT_DEBUG_MEMORY
165	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding
166	code is now the default.
167
168
169	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
170	Don't use `extern'.
171
172	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
173	code.
174
175	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)
176	[FT_DEBUG_MEMORY]: New macro.
177	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.
178	(ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug,
179	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.
180	(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,
181	FT_MEM_FREE): Redefine.
182	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,
183	FT_MEM_QRENEW_ARRAY): Redefine.
184	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,
185	FT_MEM_QREALLOC_MULT): New macros.  Update callers where
186	appropriate.
187	(FT_MEM_SET_ERROR): Slightly redefine.
188
189
190	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)
191	[FT_DEBUG_MEMORY]: New global variables, replacing...
192	(FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and
193	`line_no'.  Update all callers.
194	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer
195	overflow.
196	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,
197	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.
198
199	* src/base/ftmac.c (read_lwfn): Catch integer overflow.
200	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.
201	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.
202	(ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite.
203
204
205	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,
206	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the
207	place where the frames were entered, extracted, exited or released
208	in the memory debugger.
209
210	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
211	Call ft_mem_free.
212	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.
213	(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.
214

220	2003-09-11).  Patch provided by Huib-Jan Imbens <ft@imbens.nl>.
221
2222006-04-29  Werner Lemberg  <wl@gnu.org>

228	ft_fopen, ft_fclose, ft_fseek, ft_ftell, ft_fread, ft_smalloc,
229	ft_scalloc, ft_srealloc, ft_sfree, ft_labs): New wrapper macros for
230	C library functions.  Update all users accordingly (and catch some
231	other places where the C library function was used instead of the
232	wrapper functions).
233
234	* src/base/ftsystem.c: Don't include stdio.h and stdlib.h.

4332006-03-21  David Turner  <david@freetype.org>
434
435	* src/autofit/aflatin.c (af_latin_metrics_scale): Fix small bug
436	that crashes the auto-hinter (introduced by previous patch).
437
4382006-03-20  Werner Lemberg  <wl@gnu.org>

447
448	* include/freetype/cache/ftccache.h,
449	include/freetype/cache/ftccmap.h, include/freetype/cache/ftcglyph.h
450	include/freetype/cache/ftcimage.h include/freetype/cache/ftcmanag.h
451	include/freetype/cache/ftcmru.h include/freetype/cache/ftcsbits.h:
452	Move to...
453
454	* src/cache/ftccache.h, src/cache/ftcglyph.h, src/cache/ftcimage.h,
455	src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h,
456	src/cache/ftcmru.h: This new location.
457	Update declarations according to the changes in the corresponding
458	source files.
459
460	Note that these files are not used by FreeType clients; all public
461	APIs of the cache module have been already moved to
462	`include/freetype/ftcache.h', and all FT_CACHE_INTERNAL_XXXX_H
463	macros resolve to it.
464
465	Reason for the move is to allow modifications of the internals
466	without interferences with rogue clients.  Note that there are no
467	known clients that access the cache internals at the moment.
468

661
662	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
663	ft_contour_enclosed, ft_outline_get_orientation): Commented out.  We
664	have to wait until `FT_GlyphSlot_Own_Bitmap' is stabilized.
665	(FT_Outline_Embolden): Use `FT_Outline_Get_Orientation'.
666
6672006-02-24  Chia-I Wu  <b90201047@ntu.edu.tw>

674	sure a glyph slot owns its bitmap.  It is also marked experimental
675	and due to change.
676	(FT_GlyphSlot_Embolden): Undo the last change.  It turns out that
677	rendering the outline confuses some applications.
678
6792006-02-24  David Turner  <david@freetype.org>
680
681	* Release candidate VER-2-2-0-RC3.

695
696	Two BDF patches from Debian libfreetype6 for 2.1.10.
697

711
712	* src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to
713	support rogue clients compiled against 2.1.7 to work correctly.
714	This probably explains the GNUstep crashes with the second release
715	candidate.
716
7172006-02-23  Chia-I Wu  <b90201047@ntu.edu.tw>
718

723	ft_contour_enclosed, ft_outline_get_orientation): Another version of
724	`FT_Outline_Get_Orientation'.  This version differs from the public
725	one in that each part (contour not enclosed in another contour) of the
726	outline is checked for orientation.
727	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.
728
729	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
730	use bitmap's embolden routine when the outline one failed.

742
743	* src/truetype/ttpload.c (tt_face_load_hdmx,
744	tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not
745	actually used.
746
7472006-02-21  David Turner  <david@freetype.org>
748
749	Add a new API named FT_Get_TrueType_Engine_Type to determine whether
750	we have a patented, unpatented, or unimplemented TrueType bytecode
751	interpreter.
752
753	The FT_Get_Module_Flags API was removed consequently.
754
755	* include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed.
756	Replaced with...
757	(FT_Get_TrueType_Engine_Type): This.
758	(FT_TrueTypeEngineType): New enumeration.
759
760	* include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H):
761	New macro.

775	embedded bitmaps from being correctly listed and used.
776
777
778	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization
779	if FT_CONFIG_OPTION_OLD_INTERNALS is used.  The is necessary because
780	libXfont is directly accessing the HMTX data, unfortunately.
781	Fix some compiler warnings.
782	(tt_face_get_metrics): Ditto.
783
784
785	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of
786	character advances.
787
7882006-02-20  David Turner  <david@freetype.org>
789
790	Support binary compatibility with the X.Org server's Xfont library.
791	Note that this change unfortunately prevents memory optimizations
792	for the embedded bitmap loader.
793
794	* include/freetype/internal/sfnt.h (SFNT_Interface): Move
795	`set_sbit_strike' and `load_sbit_metrics' fields to the location of

799	FT_Size_Request.
800	(sfnt_interface): Updated.

802	* src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load
803	ttsbit0.c.
804	(tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static.
805
806	* src/sfnt/ttsbit.h: Updated.

809
810	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported
811	functions anymore.  This ensures that all FT_BASE internal functions

815	FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec,

818	ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup,
819	FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup)
820	[FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the
821	cache sub-system.  We try to recognize old legacy signatures with a
822	gross hack (hope it works).

8242006-02-17  Werner Lemberg  <wl@gnu.org>
825
826	* devel/ftoption.h: Synchronize with
827	include/freetype/config/ftoption.h.
828
8292006-02-16  David Turner  <david@freetype.org>
830
831	Massive changes to the internals to respect the internal object
832	layouts and exported functions of FreeType 2.1.7.  Note that the
833	cache sub-system cannot be fully retrofitted, unfortunately.
834
835	* include/freetype/config/ftoption.h
836	(FT_CONFIG_OPTION_OLD_INTERNALS): New macro.

852	src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c:
853	Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data
854	structures.
855
856	Move newly added structure elements to the end of the affected
857	structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is
858	defined) to assure binary compatibility with older FreeType
859	versions.
860	Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old
861	functions:
862
863	  ft_stub_set_char_sizes
864	  ft_stub_set_pixel_sizes
865
866	Rename the following internal functions to provide the old function

898	(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
899	compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
900	defined.
901
902	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
903	possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
904	(finally!)
905
906
907	For most OpenType tables, `tt_face_load_xxxx' simply loads the table
908	and `face->root' is set later in `sfnt_load_face'.  Here, we try to
909	make this work for _all_ tables.  Also improve tracing messages.
910
911	* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
912	src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
913	then exit.  Error handling or setting face->root is done later in
914	`sfnt_load_face'.
915
916	* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
917	Mac bitmap-only fonts are not scalable.
918	Check that `face->header.Units_Per_EM' is not zero.
919	(LOAD_, LOADM_): Emit pretty trace messages.
920
921	* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics
922	from `eblc'.
923
924	* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
925	(load_format_20, load_format_25, tt_face_get_ps_name): Use
926	face->max_profile.numGlyphs, instead of face->root.num_glyphs.
927
9282006-02-14  Werner Lemberg  <wl@gnu.org>
929
930	* include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in
931	documentation that negative strength values are possible.
932	Give an example call.
933
934	* include/freetype/freetype.h (FT_GlyphSlotRec): Improve
935	documentation of `outline' field.
936
937	* src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H.
938	* src/sfnt/sfdriver.c: Include ttmtx.h.
939
940	* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
941
9422006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>
943
944	* src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.
945
9462006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>
947
948	* src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
949	return error if table is missing.
950	Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.
951
952	* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
953	tables.  The last change makes Mac bitmap-only font not load and
954	this fixes it.
955
956	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation
957	error when FT_CONFIG_OPTION_INCREMENTAL is defined.
958
9592006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
960
961	Clean up the SFNT_Interface.  In this final pass, `load_hmtx' is
962	split from `load_hhea'.
963
964	* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
965	src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.
966
967	* src/sfnt/sfobjs.c (sfnt_load_face): Update.
968
9692006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
970
971	* src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of
972	code...
973
9742006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
975
976	Clean up the SFNT_Interface.  In this pass, we want to treat the
977	font directory (offset table and table directory) as a normal table
978	like the others.  This also means that TTCs are no longer recognized
979	there but in `init_face'.
980
981	* include/freetype/internal/sfnt.h (SFNT_Interface),
982	src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
983	combined and renamed to `load_font_dir'.
984
985	* src/sfnt/ttload.h, src/sfnt/ttload.c:
986	s/sfnt_dir_check/check_table_dir/.
987	`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
988	`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
989	and renamed to `tt_face_load_font_dir'.
990
991	* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
992
9932006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
994
995	Clean up the SFNT_Interface.  Table loading functions are now named
996	after the tables' tags; `hdmx' is TrueType-specific and thus the
997	code is moved to the truetype module; `get_metrics' is moved here
998	from the truetype module so that the code can be shared with the cff
999	module.
1000
1001	This pass involves no real changes.  That is, the code is moved
1002	verbatim mostly.  The only exception is the return value of
1003	`tt_face_get_metrics'.
1004
1005	* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,
1006	src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
1007	src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
1008	src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.
1009
1010	* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files.  Metrics-related
1011	tables' loading and parsing code is moved to here.
1012	Move `tt_face_get_metrics' here from the truetype module.  The
1013	return value is changed from `void' to `FT_Error'.
1014
1015	* include/freetype/internal/fttrace.h: New trace: ttmtx.
1016
1017	* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
1018	parsing code is moved here.
1019	New function `tt_face_load_prep' split from `tt_face_load_fpgm'.
1020	`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.
1021
1022	* src/cff/cffgload.c, src/cff/cffobjs.c: Update.
1023
1024	* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.
1025
10262006-02-11  Chia-I Wu  <b90201047@ntu.edu.tw>
1027
1028	* src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug...
1029
1030	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Use
1031	AF_LatinMetricsRec as the dummy metrics because we cast the metrics
1032	to it later in `af_latin_hints_link_segments'.
1033
10342006-02-11  Chia-I Wu  <b90201047@ntu.edu.tw>
1035
1036	* include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define
1037	to enable autofit CJK script support.  (#define'd by default.)
1038
1039	* src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro.
1040
1041	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure
1042	that `edge_distance_threshold' is always set.
1043	(af_latin_hints_link_segments): Potential divide-by-zero bug.
1044	Use latin constant in the scoring formula.
1045
1046	* src/autofit/afcjk.c: Minor updates due to the above three changes.
1047
1048	* docs/TODO, docs/CHANGES: Updated.
1049
10502006-02-09  Chia-I Wu  <b90201047@ntu.edu.tw>
1051
1052	Introduce experimental autofit CJK module based on akito's autohint
1053	patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.
1054
1055	* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
1056	src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
1057	Add CJK module based on akito's autohint patch.
1058
1059	* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
1060	overlap length of the segments.
1061	(AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros.
1062
1063	* src/autofit/aflatin.h (af_latin_metrics_init_widths),
1064	src/autofit/aflatin.c (af_latin_metrics_init_widths): Made
1065	`FT_LOCAL'.
1066	Use the character given by the caller.
1067	(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
1068	the thresholds.
1069
1070	* src/autofit/afloader.c (af_loader_load_g): Respect
1071	AF_SCALER_FLAG_NO_ADVANCE.
1072
10732006-02-09  Werner Lemberg  <wl@gnu.org>
1074
1075	* src/cid/cidparse.c (cid_parse_new): Remove shadowing variable.
1076
10772006-02-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
1078
1079	* src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or
1080	broken CIDFont.  Reported by Taek Kwan(TK) Lee (see ft-devel
1081	2005-11-02).
1082
10832006-02-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
1084
1085	* builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts'
1086	option on UNIX platform.  It has been broken since 2006-01-11.
1087
10882006-02-01  Werner Lemberg  <wl@gnu.org>
1089
1090	* src/otvalid/module.mk: s/otvalid_module_class/otv_module_class/.
1091	* src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/.
1092
1093	* builds/unix/unixddef.mk: Actually do define PLATFORM (fixing
1094	change from 2006-01-31).
1095	(TOP_DIR, OBJ_DIR): Update.
1096
1097	* builds/unix/install.mk (install): Fix path for ftmodule.h.
1098
1099	* Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use
1100	`?=' where appropriate.
1101
1102	* builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR),
1103	builds/win32/w32-dev.mk (TOP_DIR): Removed.  Defined elsewhere.
1104
11052006-01-31  Werner Lemberg  <wl@gnu.org>
1106
1107	Implement new, simplified module selection.  With GNU make it is now
1108	sufficient to modify a single file, `modules.cfg', to control the
1109	inclusion of modules and base extension files.
1110
1111	This change also fixes the creation of ftmodule.h; it now depends on
1112	`modules.cfg' and thus is rebuilt only if necessary.
1113
1114	Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
1115	default location.
1116
1117	* modules.cfg: New file.
1118
1119	* builds/freetype.mk: Don't include `modules.mk'.
1120	Include all `rules.mk' files as specified in `modules.cfg'.
1121	(FTOPTION_FLAG, FTOPTION_H): New variables.
1122	(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
1123	Add FTOPTION_FLAG.
1124	($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
1125	(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
1126	(INCLUDES): Add DEVEL_DIR.
1127	(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
1128	OBJ_M, OBJ_S): Use `:=', not `='.
1129	(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
1130	(distclean): Add remove_ftmodule_h.
1131
1132	* builds/modules.mk: (MODULE_LIST): Removed.
1133	(make_module_list, clean_module_list): Replace targets
1134	with...
1135	(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
1136	variables.  Reason for the change is that it is not possible to have
1137	a phony prerequisite which is run only if the target file must be
1138	rebuilt (phony prerequisites act like subroutines and are *always*
1139	executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
1140	changed.
1141	Update all callers.
1142	($FTMODULE_H)): Rule to create `ftmodule.h', depending on
1143	`modules.cfg'.
1144
1145	* builds/toplevel.mk: Rewrite and simplify module handling.
1146	(MODULES_CFG, FTMODULE_H): New variables.
1147	Include MODULES_CFG.
1148	(MODULES): New variable to include all `module.mk' and `rules.mk'
1149	files.  We no longer use make's `wildcard' function for this.
1150
1151	* Makefile (USE_MODULES): Remove.  Update all users.
1152	(OBJ_DIR): Define it here.
1153
1154	* src/*/module.mk: Change
1155
1156	    make_module_list: foo
1157	    foo: ...
1158
1159	to
1160
1161	    FTMODULE_H_COMMANDS += FOO
1162	    define FOO
1163	    ...
1164	    endef
1165
1166	in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.
1167
1168	* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.
1169
1170	* builds/unix/detect.mk (setup): Always execute `configure' script.
1171	(have_mk): Rename to...
1172	(have_Makefile): This.
1173	Don't use `strip' function.
1174
1175	* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
1176	defined.
1177	(have_mk): Don't use `strip' function.
1178	Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
1179	accordingly).
1180
1181	* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.
1182
1183	* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
1184	builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
1185	BUILD_DIR but DEVEL_DIR for development header files.
1186
1187	* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
1188	builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
1189	(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.
1190
1191	* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
1192	builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.
1193
1194	* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
1195	development header files.
1196	Don't define PLATFORM.
1197
1198	* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
1199	Update snippet taken from autoconf's m4sh.m4 to current CVS version.
1200	Be more verbose.
1201
1202	* include/freetype/config/ftmodule.h: Add comments -- this file is
1203	no longer used if FreeType is built with GNU make.
1204
1205	* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
1206	docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
1207	Other minor updates.
1208
1209	* modules.txt: Removed.  Contents included in `modules.cfg'.
1210
1211
1212	* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
1213	FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.
1214
1215	* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
1216	FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
1217	[FT_STRICT_ALIASING]: Implement.
1218
12192006-01-31  Chia-I Wu  <b90201047@ntu.edu.tw>
1220
1221	* src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c
1222	(cid_face_init), src/pfr/pfrobjs.c (pfr_face_init),
1223	src/type1/t1objs.c (T1_Face_Init): Set face->height to MAX(1.2 *
1224	units_per_EM, ascender - descender).
1225
12262006-01-31  Chia-I Wu  <b90201047@ntu.edu.tw>
1227
1228	* include/freetype/internal/t1types.h (AFM_FontInfo),
1229	src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',
1230	`Ascender', and `Descender' from an AFM.
1231
1232	* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.
1233
1234	* include/freetype/freetype.h (FT_FaceRec): Mention that fields may
1235	be changed after file attachment.
1236
12372006-01-28  Werner Lemberg  <wl@gnu.org>
1238
1239	* src/*/module.mk (.PHONY): Add.
1240
12412006-01-27  Werner Lemberg  <wl@gnu.org>
1242
1243	* README, docs/FTL.TXT: Fix email address for bug reports.
1244	Other minor formatting.
1245
1246	* devel/ftoption.h: Synchronize with
1247	include/freetype/config/ftoption.h.
1248
1249	* src/autofit/module.mk (add_autofit_module), src/bdf/module.mk
1250	(add_bdf_module), src/type42/module.mk (add_type42_driver): Fix
1251	whitespace.
1252
1253	* src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv
1254	renderer classes.
1255
12562006-01-27  David Turner  <david@freetype.org>
1257
1258	* builds/unix/configure.ac: Fix build problem on Cygwin.
1259
1260	* builds/unix/install.mk (install): Don't install the internal
1261	headers, and remove existing ones if found in the target install
1262	directory.
1263
1264	* src/autofit/afwarp.c: Add simple #ifdef to prevent compilation
1265	if the warp hinter isn't active (it shouldn't, still experimental).
1266
1267	* Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid'
1268	and `otvalid' from the list of modules that are linked statically
1269	to a given FreeType library.  Functionality has been moved to the
1270	`ftvalid' CVS module.
1271
1272	Note also that current Make-based build system still compiles the
1273	modules though.
1274
1275	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro
1276	which controls the definitions of the memory management functions to
1277	avoid warnings with recent versions of GCC.  This macro is only here
1278	to be disabled, in case we detect problems with the new scheme.
1279
1280	NOTE: Disable macro to use the memory debugger -- this will be fixed
1281	      later!
1282
1283	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,
1284	FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]:
1285	New versions.
1286
1287
1288	* builds/win32/visualc/freetype.dsp: Updating project file to
1289	define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from
1290	compilation.
1291
1292
1293	* builds/freetype.mk (FT_CFLAGS), Jamfile (DEFINES): Define the
1294	macro FT2_BUILD_LIBRARY when compiling the library.
1295
1296	* include/freetype/config/ftheader.h: Remove inclusions of internal
1297	headers except if the macro FT2_BUILD_LIBRARY is defined.
1298
1299
1300	* include/freetype/internal/psaux.h (AFM_KernPair, AFM_TrackKern,
1301	AFM_FontInfo): Move structure declarations to...
1302	* include/freetype/internal/t1types.h: This file.
1303
1304
1305	* (many files): Fix compiler warnings.
1306	Various minor reorganizations.
1307
1308
1309	* src/cff/cffload.c (cff_font_done): Don't free static array
1310	`subfonts'.
1311
1312	* src/otvalid/otvcommn.c (otv_ClassDef_validate),
1313	src/otvalid/otvgpos.c (otv_x_sxy): Fix debugging information.
1314
1315
1316	Get rid of writable static variables (i.e., the string table) in
1317	afmparse, and fix compilation in FT2_MULTI mode.
1318

1331
1332	* include/freetype/freetype.h (FT_Select_Size): Rename the second
1333	argument from `idx' to `strike_index'.

1335	this enum.
1336
1337	* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,

1342	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
1343	FT_Request_Metrics): New base functions to set the font metrics.  They
1344	were part of FT_Select_Size/FT_Request_Size and are made independent

1346
1347	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
1348	only when driver's size_select/size_request is NULL.  That is, drivers
1349	should set the metrics themselves.
1350	(FT_Match_Size): Round before matching.  This was what we did and it
1351	does cause some problems without rounding.

1358	metrics are not reliable, e.g., the sign of the descender is wrong for
1359	some fonts.
1360
1361	* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
1362	(tt_size_request): Set the font metrics.

1370
1371	* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
1372	files were committed.  Just a catch-up.
1373	(PS_Conv_ToFixed): Remove the `goto'.
1374	(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.
1375
1376	* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
1377	tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
1378	(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
1379	advertised metrics in `available_sizes' are different from those
1380	actually used.

1726	MPW compiler.
1727
17282005-12-23  David Turner  <david@freetype.org>
1729
1730	* Jamfile (RefDoc), docs/reference/README: Fix it so that `jam
1731	refdoc' works correctly to generate the API reference in
1732	`docs/reference'.
1733
1734	* src/tools/docmaker/tohtml.py (print_html_field,
1735	print_html_field_list): Update to output nicer fields lists in the
1736	API reference.
1737
1738	* src/base/ftobjs.c (FT_Load_Glyph): FT_LOAD_TARGET_LIGHT now
1739	forces auto-hinting.
1740
1741	* freetype/freetype.h: Updating the documentation for
1742	FT_LOAD_TARGET_XXX and FT_Render_Mode values.

1745
1746	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Count scalable faces
1747	in supported formats (sfnt, LWFN) only, and ignore bitmap faces in
1748	unsupported formats (fbit, NFNT).  The number of available faces are
1749	passed via face->num_faces.  If bitmap faces are embedded in sfnt
1750	resource, face->num_fixed_size is correctly set.  In public API,
1751	FT_New_Face() and FT_New_Face_From_FSSpec() count the faces as
1752	FT_GetFile_From_Mac_Name(), which ignores NFNT resources.

1775
1776	Change the implementation of the LIGHT hinting mode to completely
1777	disable horizontal hinting.  This is an experimental effort to
1778	integrate David Chester's latest patch without affecting the other
1779	hinting modes as well.
1780
1781	Note that this doesn't force auto-hinting for all fonts, however.
1782
1783	* src/autofit/afhints.c (af_glyph_hints_reload): Don't set
1784	scaler_flags here but...
1785	(af_glyph_hints_rescale): Here.
1786
1787	* src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal
1788	hinting for `light' hinting mode.
1789
1790
1791	* Jamfile: Small fix to ensure that ftexport.sym is placed into the
1792	same location as other generated objects (i.e., within the `objs'
1793	directory of the current directory).
1794
1795
1796	Add support for an embedded `BDF ' table within SFNT-based bitmap
1797	font files.  This is used to store atoms & properties from the
1798	original BDF fonts that were used to generate the font file.
1799
1800	The feature is controlled by TT_CONFIG_OPTION_BDF within
1801	`ftoption.h' and is used to implement FT_Get_BDF_Property for these
1802	font files.
1803
1804	At the moment, this is still experimental, the BDF table format
1805	isn't cast into stone yet.
1806
1807	* include/freetype/config/ftoption.h (TT_CONFIG_OPTION_BDF): New
1808	macro.
1809

1866
1867	Major update to distinguish between unsorted and overlapping
1868	segments for cmap format 4.  For overlapping but sorted segments,
1869	which is previously considered unsorted, we still use binary search.
1870
1871	* src/sfnt/ttcmap.h (TT_CMapRec_): Replace `unsorted' by `flags'.

1878	(tt_cmap4_next): Updated accordingly.
1879	Take care of overlapping segments.
1880	(tt_cmap4_validate): Make sure the subtable is large enough.
1881	Do not check glyph_ids because some fonts set the length wrongly.
1882	Also, if all segments have offset 0, glyph_ids is always invalid.
1883	It does not cause any problem so far only because the check misses
1884	equality.
1885	Distinguish between unsorted and overlapping segments.
1886	(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions
1887	to do `charcode => glyph index' by linear/binary search.
1888	(tt_cmap4_char_index, tt_cmap4_char_next): Use

1897	(tt_cmap12_char_map_binary): New function to do `charcode => glyph
1898	index' by binary search.
1899	(tt_cmap12_char_index, tt_cmap12_char_next): Use
1900	tt_cmap12_char_map_binary.
1901	(tt_face_build_cmaps): Check table and offset correctly (equality is
1902	missing).
1903
19042005-11-15  Detlef Würkner  <TetiSoft@apg.lahn.de>
1905
1906	* builds/amiga/smakefile: Adjusted the compiler options
1907	to the current sources, now really builds the gxvalid, gzip
1908	and psnames modules.
1909
1910	* builds/amiga/src/base/ftsystem.c: The assumed Seek() position
1911	in the file cache was off by one byte which could cause false
1912	errors in font files.

2307
2308	`SING Glyphlet' is an extension to OpenType developed by Adobe
2309	primarily to facilitate adding supplemental glyphs to an OpenType
2310	font (with emphasis on, but not necessarily limited to, gaiji to a
2311	CJK font).  A SING Glyphlet Font is an OpenType font that contains
2312	the outline(s), either in a `glyf' or `CFF' table, for a glyph;
2313	`cmap', `BASE', and `GSUB' tables are present with the same format
2314	and functionality as a regular OpenType font; there are no `name',
2315	`head', `OS/2', and `post' tables; there are two new tables, `SING'
2316	which contains details about the glyphlet, and `META' which contains
2317	metadata.
2318
2319	Further information on the SING Glyphlet format can be found at:
2320
2321	  https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf
2322
2323	* include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for
2324	the OpenType tables `SING' and `META'.  These two tables are used in

2579
2580	* src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline
2581	to (0,0) if bit 1 of the `head' table isn't set.  This improves

2627	context here.
2628	(tt_slot_init): New function to create extra points for the internal
2629	glyph loader.  We then use it directly, instead of face's glyph
2630	loader, when loading glyph.
2631
2632	* src/truetype/ttdriver.c (tt_driver_class): Use tt_slot_init for
2633	glyph slot initialization.

2635	if size is NULL.
2636
2637	* src/truetype/ttgload.c: Heavy cleanup and refactoring.

2650	Forget glyph frame before calling TT_Process_Simple_Glyph.
2651	Use TT_LOADER_SET_PP.
2652	Scale all four phantom points.

2654	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
2655	new functions.
2656	(TT_Load_Glyph): Set various fields of `glyph' here, not in
2657	load_truetype_glyph and compute_glyph_metrics.
2658	Split off some functionality to ...
2659	(load_sbit_image, tt_loader_init): These new functions.
2660	(compute_glyph_metrics): Call FT_Outline_Get_CBox.

2803
2804	* src/truetype/ttgload.c (compute_glyph_metrics): Compute
2805	vertBearingY to make glyphs centered vertically.
2806	Fix some bugs in vertical metrics:
