  117. 2006-05-03  David Turner  <david@freetype.org>
  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.  
  126. 2006-05-03  Werner Lemberg  <wl@gnu.org>
  127.  
  128.         * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.
  129.  
  130. 2006-05-02  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.  
  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.
  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_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.

  200.         * src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.
  201.         * src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.

  205.         * include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,

  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.  
  215. 2006-04-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  216.  
  217.         * src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos

  544.  
  545.         * modules.cfg (BASE_EXTENSIONS): Compile in ftgxval.c by default to

  564.  
  565.         * src/cache/ftccache.c (ftc_node_destroy): Mark as FT_BASE_DEF since

  693.  
  694. 2006-02-23  David Turner  <david@freetype.org>
  695.  
  696.         Two BDF patches from Debian libfreetype6 for 2.1.10.

  704.         module) which still crashes under Sarge.
  705.  
  706.         * src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,

  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>

  723.         ft_contour_enclosed, ft_outline_get_orientation): Another version of

  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.

  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,

  848.         src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h,
  849.         src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c,

  851.         src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c,
  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
  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.  
  1073. 2006-02-09  Werner Lemberg  <wl@gnu.org>
  1074.

  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.

  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
  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.

  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.

  1217.         [FT_STRICT_ALIASING]: Implement.

  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,

  1287.  
  1288.         * builds/win32/visualc/freetype.dsp: Updating project file to
  1289.         define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from
  1290.         compilation.

  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.

  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...

  1329.  
  1330. 2006-01-23  Chia-I Wu  <b90201047@ntu.edu.tw>
  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

  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.

  1354.         (tt_size_select): Set the font metrics.
  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,
  1366.         src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.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.
  1381.  
  1382. 2006-01-23  Chia-I Wu  <b90201047@ntu.edu.tw>
  1383.  
  1384.         * src/psaux/psaux.c src/psaux/psauxmod.c src/type1/t1driver.c: Make
  1385.         AFM parser optional, controlled by `T1_CONFIG_OPTION_NO_AFM'.
  1386.  
  1387. 2006-01-22  Werner Lemberg  <wl@gnu.org>
  1388.  
  1389.         * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
  1390.         `texinfo' CVS module at savannah.gnu.org.
  1391.  
  1392. 2006-01-21  Werner Lemberg  <wl@gnu.org>
  1393.

  1404. 2006-01-20  David Turner  <david@freetype.org>
  1405.  
  1406.         Adding experimental implementation of `warp hinting' (new hinting
  1407.         algorithm for gray-level and LCD rendering).  It is disabled by
  1408.         default, you need to #define AF_USE_WARPER in aftypes.h.
  1409.  
  1410.         * src/autofit/afhints.c (af_glyph_hints_scale_dim) [AF_USE_WARPER]:
  1411.         New function.

  1773.  
  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
  1808.         macro.
  1809.  
  1810.         * include/freetype/config/ftstdlib.h (ft_memchr): New macro.

  1825.         (sfnt_service_bdf) [TT_CONFIG_OPTION_BDF]: New service.
  1826.         (sfnt_services) [TT_CONFIG_OPTION_BDF]: Add sfnt_service_bdf.

  1835.  
  1836. 2005-12-07  Werner Lemberg  <wl@gnu.org>
  1837.  
  1838.         * src/sfnt/sfobjc.c (sfnt_init_face): Move tag check to...
  1839.         * src/sfnt/ttload.c (sfnt_init): Here, before handling TTCs.
  1840.  
  1841. 2005-12-06  Chia-I Wu  <b90201047@ntu.edu.tw>
  1842.  
  1843.         * src/truetype/ttobjs.c (tt_size_init): size->ttmetrics.valid is

  1848.  
  1849.         * src/type42/t42objs.c (T42_Face_Init): Replace call to
  1850.         FT_New_Memory_Face with call to FT_Open_Face to pass `params'.
  1851.  
  1852. 2005-11-30  Werner Lemberg  <wl@gnu.org>
  1853.  
  1854.         * docs/CHANGES: Document ftdump's `-v' option.

  1858.         s/TT_CMAP_FLAG_OVERLAPPED/TT_CMAP_FLAG_OVERLAPPING/.
  1859.  
  1860. 2005-11-30  Chia-I Wu  <b90201047@ntu.edu.tw>
  1861.

  1863.         tt_cmap12_char_map_binary): Fix compiler warnings.
  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.

  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.

  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.
  1913.  
  1914. 2005-11-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

  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:

  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 is no need to adjust `top'.
