 124         Update callers accordingly.
 125
 126 2006-05-03  Werner Lemberg  <wl@gnu.org>

 141         Remove `extern'.
 142
 143 2006-05-02  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.

 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_MemTable_Rec) [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.

 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.

 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).

 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
 469         * builds/unix/install.mk (install): Don't install headers from

 532         * src/base/ftobjs.c (FT_Done_Library): Remove modules in reverse

 544
 545         * modules.cfg (BASE_EXTENSIONS): Compile in ftgxval.c by default to
 546         build ftvalid in ft2demos.  It works as dummy ABI if gxvalid is not
 547         built.
 548
 549 2006-02-27  Werner Lemberg  <wl@gnu.org>
 550

 563         parameters.
 564
 565         * src/cache/ftccache.c (ftc_node_destroy): Mark as FT_BASE_DEF since
 566         it needs to be exported for rogue clients.
 567
 568         * src/pshinter/pshglob.c (psh_blues_set_zones_0): Prevent problems
 569         with malformed fonts which have an odd number of blue values (these

 594         (ft_glyphslot_grid_fit_metrics, FT_Load_Glyph) [GRID_FIT_METRICS]:
 595         Re-enable glyph metrics grid-fitting.  It is now done in the base
 596         layer.
 597         (FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and
 598         height are not too small or too large, just like we were doing in
 599         2.1.10.
 600
 601         * src/autofit/afloader.c (af_loader_load_g): The vertical metrics

 612
 613         * src/base/ftobjs.c (ft_recompute_scaled_metrics): Re-enable
 614         conservative rounding of metrics to avoid breaking clients like
 615         Pango (see http://bugzilla.gnome.org/show_bug.cgi?id=327852).

 625
 626         Fix compiler warnings as well as C++ compilation problems.

 632         src/tools/apinames.c, src/truetype/ttdriver.c: Add various casts,
 633         initialize variables, and decorate functions with FT_CALLBACK_DEF,
 634         etc., to fix compiler warnings (and C++ compiling errors).
 635
 636         * src/cache/ftcbasic.c: Fix `-Wmissing-prototypes' warnings with
 637         gcc.

 660 2006-02-24  Chia-I Wu  <b90201047@ntu.edu.tw>
 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
 667 2006-02-24  Chia-I Wu  <b90201047@ntu.edu.tw>
 668

 673         src/base/ftsynth.c (FT_GlyphSlot_Own_Bitmap): New function to make
 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
 679 2006-02-24  David Turner  <david@freetype.org>
 680

 682         ----------------------------------
 683
 684         * src/cache/ftcbasic.c: Correct compatibility hack bug.
 685
 686 2006-02-24  Chia-I Wu  <b90201047@ntu.edu.tw>
 687
 688         * include/freetype/freetype.h (FT_Size_RequestRec): Change the type

 691         New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales
 692         directly.
 693
 694 2006-02-23  David Turner  <david@freetype.org>
 695
 696         Two BDF patches from Debian libfreetype6 for 2.1.10.
 697
 698         * src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width
 699         glyphs.
 700         Fix a problem with large encodings.
 701
 702
 703         Fix binary compatibility issues for gnustep-back (GNUstep backend
 704         module) which still crashes under Sarge.
 705
 706         * src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,
 707         FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data
 708         structures and enumerations.
 709         (FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New
 710         compatibility code.
 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
 717 2006-02-23  Chia-I Wu  <b90201047@ntu.edu.tw>
 718

 722         * src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
 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.
 731
 732 2006-02-22  Chia-I Wu  <b90201047@ntu.edu.tw>
 733
 734         * modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI
 735         compatibility.
 736
 737         * src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak.
 738
 739         * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,
 740         tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit
 741         loading.  (Only tested with bit aligned sbit with x_pos == 0.)
 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
 747 2006-02-21  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.
 762
 763         * src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
 764         (FT_Module_Get_Flags): Removed.  Replaced with...
 765         (FT_Get_TrueType_Engine_Type): This.
 766
 767         * src/truetype/ttdriver.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
 768         (tt_service_truetype_engine): New service structure.
 769         (tt_services): Register it.
 770
 771         * include/freetype/internal/services/svtteng.h: New file.
 772
 773
 774         * src/sfnt/sfobjs.c (sfnt_load_face): Fix silly bug that prevented
 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
 788 2006-02-20  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
 796         version 2.1.8.
 797
 798         * src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call
 799         FT_Size_Request.
 800         (sfnt_interface): Updated.
 801
 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.
 807
 808 2006-02-17  David Turner  <david@freetype.org>
 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
 812         are available for dynamic linking.
 813
 814         * include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE,
 815         FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec,
 816         FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New,
 817         FTC_OldImage_Desc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx,
 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).
 823
 824 2006-02-17  Werner Lemberg  <wl@gnu.org>
 825
 826         * devel/ftoption.h: Synchronize with
 827         include/freetype/config/ftoption.h.
 828
 829 2006-02-16  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.
 837
 838         * include/freetype/ftcache.h, include/freetype/cache/ftccache.h,
 839         include/freetype/cache/ftccmap.h,
 840         include/freetype/internal/ftcalc.h,

 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
 867         names as stubs:
 868
 869           FT_Alloc          -> ft_mem_alloc
 870           FT_QAlloc         -> ft_mem_qalloc
 871           FT_Realloc        -> ft_mem_realloc
 872           FT_QRealloc       -> ft_mem_qrealloc
 873           FT_Free           -> ft_mem_free
 874           FT_Alloc_Debug    -> ft_mem_alloc_debug
 875           FT_QAlloc_Debug   -> ft_mem_qalloc_debug
 876           FT_Realloc_Debug  -> ft_mem_realloc_debug
 877           FT_QRealloc_Debug -> ft_mem_qrealloc_debug
 878           FT_Free_Debug     -> ft_mem_free_debug
 879
 880 2006-02-15  Chia-I Wu  <b90201047@ntu.edu.tw>
 881
 882         * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
 883         unused `max_points' and `max_contours'.
 884
 885         * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
 886         (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.
 887
 888         * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
 889         `max_components'.
 890
 891         * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
 892         `loadSize' and `loadStack'.
 893
 894         * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
 895         src/sfnt/ttload.c (tt_face_load_maxp): Update.
 896
 897         * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
 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
 928 2006-02-14  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/sfobjc.s: Inckude 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
 942 2006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>
 943
 944         * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.
 945
 946 2006-02-14  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
 959 2006-02-13  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
 969 2006-02-13  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
 974 2006-02-13  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
 993 2006-02-13  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
1026 2006-02-11  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
1034 2006-02-11  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
1050 2006-02-09  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

1104
1105 2006-01-31  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

1164             endef

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),

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

1230         `Ascender', and `Descender' from an AFM.
1231
1232         * src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.

1242
1243         * README, docs/FTL.TXT: Fix email address for bug reports.
1244         Other minor formatting.
1245

1254         renderer classes.
1255
1256 2006-01-27  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,

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,

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
1319         * src/psaux/afmparse.c: Include ft2build.h and FT_FREETYPE_H.
1320         (AFM_MAX_ARGUMENTS): Define...
1321         * src/psaux/afmparse.h: Here.
1322         * src/psaux/Jamfile (_sources): Add afmparse.
1323

1325
1326         * src/type1/t1afm.c: Don't include FT_INTERNAL_TYPE1_TYPES_H but
1327         FT_INTERNAL_POSTSCRIPT_AUX_H.
1328         * src/type1/t1afm.h: Include FT_INTERNAL_TYPE1_TYPES_H.

1331
1332         * include/freetype/freetype.h (FT_Select_Size): Rename the second
1333         argument from `idx' to `strike_index'.
1334         (FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
1335         this enum.
1336
1337         * include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,
1338         FT_REQUEST_HEIGHT): New macros to get the width and height of a
1339         request, in fractional pixels.
1340
1341         * include/freetype/internal/ftobjs.h (FT_Select_Metrics,
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
1345         functions so that metrics are not set again and again.
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.
1352
1353         * src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c

1355         s/index/strike_index/.
1356         The scaled metrics are always preferred over strikes' metrics, even
1357         when some strike is selected.  This is done because the strikes'
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.
1363         Call cff_size_select/tt_size_select when some strike is matched.
1364
1365         * src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c,

1367         src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
1368         Set the font metrics.
1369         s/index/strike_index/.
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.

1386
1387 2006-01-22  Werner Lemberg  <wl@gnu.org>
1388

1397         to avoid compiler warnings.
1398
1399         * src/autofit/afwarp.c (af_warper_compute_line_best): Remove

1732         `docs/reference'.
1733
1734         * src/tools/docmaker/tohtml.py (print_html_field,

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.

1774 2005-12-13  David Turner  <david@freetype.org>
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_fiags 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

1864
1865 2005-11-29  Chia-I Wu  <b90201047@ntu.edu.tw>
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'.
1872         (TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.
1873
1874         * src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
1875         (TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
1876         (tt_cmap4_reset): Removed.
1877         (tt_cmap4_init): Updated accordingly.
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
1889         tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
1890         (tt_face_build_cmaps): Treat the return value of validator as flags
1891         for cmap.
1892
1893 2005-11-29  Chia-I Wu  <b90201047@ntu.edu.tw>
1894
1895         * src/sfnt/ttcmap.c (TT_CMap12Rec_, tt_cmap12_init, tt_cmap12_next):
1896         New structures and functions for fast `next char'.
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
1904 2005-11-15  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.

2087         symbols or Windows .DEF files by parsing the public headers with the
2088         `apinames' tool located in src/tools/apinames.c.
2089
2090         Only tested on Unix at the moment.  On Windows, the .DEF file is

2123         FT_GLYPHLOADER_CHECK_C, FT_GLYPHLOADER_CHECK_POINTS): New macros for
2124         checking points and contours.  Update callers to use
2125         FT_GLYPHLOADER_CHECK_POINTS instead of FT_GlyphLoader_CheckPoints
2126         at profile-detected hot-spots.
2127
2128         * src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Set `adjust'
2129         to 0 to not call `AdjustPoints' every time.

2146         names with digits aren't read correctly.
2147         (usage): Updated.
2148         (main): New option `-o' to control output file name.
2149         New option `-d' to indicate DLL file name.

2303
2304         * freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
2305         font to have no `head' table if tables `SING' and `META' are
2306         present; this is to support `SING Glyphlet'.
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 functionaliy 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           http://www.adobe.com/products/indesign/sing_gaiji.html
2322
2323         * freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
2324         macros for the OpenType tables `SING' and `META'.  These two tables
2325         are used in SING Glyphlet Format fonts.

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

2585
2586         * src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of

2588         ttmetrics.valid set to false.
2589

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

2642         Use loader->pp values instead of recalculation.
2643         Use TT_Hint_Glyph.
2644         No need to save/restore loader->stream before and after
2645         TT_Vary_Get_Glyph_Deltas now.
2646         (TT_LOADER_SET_PP): New macro to calculate and set the four phantom
2647         points.
2648         (load_truetype_glyph): Never set exec->glyphSize to 0.  This closes
2649         Savannah bug #13107.
2650         Forget glyph frame before calling TT_Process_Simple_Glyph.
2651         Use TT_LOADER_SET_PP.
2652         Scale all four phantom points.
2653         Split off some functionality to ...
2654         (TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
2655         new functions.

2658         Split off some functionality to ...
2659         (load_sbit_image, tt_loader_init): These new functions.

2724         has been confirmed by the MS developers that it is indeed a bug
2725         which won't be fixed in the very near future).
2726
2727         * Jamfile (FT2_COMPONENTS): Include otvalid (again).
2728
2729         * src/otvalid/otvcommn.h (OTV_NAME, OTV_FUNC): New macros.
2730         (OTV_NEST1, OTV_NEST2, OTV_NEST3): Use OTV_NAME and OTV_FUNC to
2731         avoid argument expansion by argument prescan.
2732         Append `Func' to all affected macros and change them to take just a
2733         single argument.  Example: `AttachList' is renamed to
2734         `AttachListFunc'.
2735
2736         * src/otvalid/otvgdef.c, src/otvalid/otvgpos.c,
2737         src/otvalid/otvgsub.c, src/otvjstf.c: Append `Func' to macros
2738         affected by the changes to OTV_NESTx and modify them to take just a
2739         single argument.

2742
2743         * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: New function
2744         ft_glyphslot_grid_fit_metrics.
2745
2746         * src/truetype/ttgload.c (compute_glyph_metrics): Use
2747         ft_glyphslot_grid_fit_metrics.
2748
2749         * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
2750         (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use
2751         ft_glyphslot_grid_fit_metrics.
2752         FT_Outline_Get_CBox is called twice.
2753
2754         * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
2755         reasonable values when emboldening outline glyphs.  The theoretic
2756         ones are unrealistic.
2757
2758 2005-06-16  Chia I Wu  <b90201047@ntu.edu.tw>
2759
2760         * src/base/ftoutln.c (FT_Outline_Embolden): Strength should be
2761         halved.
2762
2763         * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Change the default
2764         strength.
2765         Don't increase slot->advance.y.
2766
2767 2005-06-16  Werner Lemberg  <wl@gnu.org>
2768
2769         * include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.
2770         (FREETYPE_PATCH): Set to 0.
2771
2772         * builds/unix/configure.ac (version_info): Set to 9:9:3.
2773         Currently, we are still binary compatible.
2774
2775         * builds/win32/visualc/index.html,
2776         builds/win32/visualc/freetype.dsp,
2777         builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/.
2778
2779         * builds/freetype.mk (refdoc), README, Jamfile (RefDoc):
2780         s/2.1.9/2.1.10/.
2781
2782         * docs/CHANGES, docs/VERSION.DLL: Updated.
2783
2784         * ChangeLog: Split off older entries into...
2785         * ChangeLog.20, ChangeLog.21: These new files.
2786
2787 2005-06-15  Kirill Smelkov  <kirr@mns.spb.ru>
2788
2789         The next release will be 2.2.0, so don't worry about source code
2790         backwards compatibility.
2791
2792         * include/freetype/ftimage.h (FT_Outline_MoveToFunc,
2793         FT_Outline_LineToFunc, FT_Outline_ConicToFunc,
2794         FT_Outline_CubicToFunc, FT_SpanFunc, FT_Raster_RenderFunc),
2795         include/freetype/ftrender.h (FT_Glyph_TransformFunc,
2796         FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Decorate
2797         parameters with `const' where appropriate.
2798
2799 2005-06-15  Chia I Wu  <b90201047@ntu.edu.tw>
2800
2801         * src/sfnt/ttsbit.c (tt_face_load_sbit_image): Compute vertBearingY
2802         to make glyphs centered vertically.
2803
2804         * src/truetype/ttgload.c (compute_glyph_metrics): Compute
2805         vertBearingY to make glyphs centered vertically.
2806         Fix some bugs in vertical metrics:
2807
2808           . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
2809             units.
2810           . As we use the glyph's cbox to calculate the top bearing now
2811             there iss no need to adjust `top'.
2812
2813 2005-06-15  Werner Lemberg  <wl@gnu.org>
2814
2815         * src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
2816         in sync with OTV_OPTIONAL_OFFSET.  Reported by YAMATO Masatake.
2817
2818 2005-06-13  Werner Lemberg  <wl@gnu.org>
2819
2820         * docs/release: Update.
