Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
Werner Lemberg 8b281f83 2014-01-23T08:14:53 Fix Savannah bug #41309. * src/type1/t1load.c (t1_parse_font_matrix): Properly handle result of `T1_ToFixedArray'. * src/cid/cidload.c (cid_parse_font_matrix): Synchronize with `t1_parse_font_matrix'. * src/type42/t42parse.c (t42_parse_font_matrix): Synchronize with `t1_parse_font_matrix'.

Werner Lemberg e8ed2d62 2013-08-01T12:20:20 Another round of cppcheck nitpicks. The call was (from the top-level of the FreeType tree): cppcheck --force \ --enable=all \ -I /usr/include \ -I /usr/local/include \ -I /usr/lib/gcc/i586-suse-linux/4.7/include \ -I include \ -I include/freetype \ -I include/freetype/config \ -I include/freetype/internal \ -DFT2_BUILD_LIBRARY \ . &> cppcheck.log using cppcheck git commit f7e93f99. Note that cppcheck still can't handle `#include FOO' (with `FOO' a macro). */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/gxvalid/*: Comment out redundant code or guard it with FT_DEBUG_LEVEL_TRACE.
Werner Lemberg 94152819 2013-05-04T16:40:12 More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Alexei Podtelezhnikov 79180ad0 2012-11-27T21:36:20 [cid, type1, type42] Clean up units_per_EM calculations. * src/cid/cidload.c (cid_parse_font_matrix): Updated. * src/type1/t1load.c (t1_parse_font_matrix): Updated. * src/type42/t42parse.c (t42_parse_font_matrix): Updated.
Werner Lemberg 6b5b6f39 2012-02-24T12:26:25 Prepare source code for amalgamation (6/6). * src/cff/cffdrivr.c: s/Load_Glyph/cff_glyph_load/. * src/cid/cidload.c: s/parse_font_matrix/cid_parse_font_matrix/. s/t1_init_loader/cid_init_loader/. s/t1_done_loader/cid_done_loader/. * src/pxaux/t1cmap.c: s/t1_get_glyph_name/psaux_get_glyph_name/. * src/truetype/ttdriver.c: s/Load_Glyph/tt_glyph_load/. * src/type1/t1load.c: s/parse_font_matrix/t1_parse_font_matrix/.
Braden Thomas 14a16e34 2011-11-08T08:27:42 [cid] Various loading fixes. * src/cid/cidload.c (cid_load_keyword) <default>, (parse_font_matrix, parse_expansion_factor): Correctly check number of dictionaries. (cid_read_subrs): Protect against invalid values of `num_subrs'. Assure that the elements of the `offsets' array are ascending.
Werner Lemberg 858abbed 2009-06-26T06:15:41 For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings.
Werner Lemberg 15b60bb5 2009-03-03T21:35:32 Formatting, copyright years.
David Turner 01ca4da2 2009-03-03T13:28:59 Remove ABI-breaking field in public PS_InfoFontRec definition. Instead, we define a new internal PS_FontExtraRec structure to hold the additionnal field, then place it in various internal positions of the corresponding FT_Face derived objects.

Jens Claudius 9950adcc 2006-08-13T12:14:36 * freetype2/include/freetype/internal/psaux.h: (enum T1_TokenType_): add T1_TOKEN_TYPE_KEY. (struct T1_FieldRec_) add `dict'. Add macros T1_FIELD_DICT_FONTDICT and T1_FIELD_DICT_PRIVATE. Change T1_NEW_XXX and T1_FIELD_XXX macros to take the dictionary where the PS keywords is expected as an additional argument. * freetype2/src/cid/cidload.c: (T1_FieldRec): Adjust invocations of T1_FIELD_XXX. * freetype2/src/cid/cidtoken.h: Adjust invocations of T1_FIELD_XXX. * freetype2/src/psaux/psobjs.c: Add macro FT_COMPONENT for tracing. (ps_parser_to_token): Report a PostScript key as T1_TOKEN_TYPE_KEY instead as T1_TOKEN_TYPE_ANY. (ps_parser_load_field): Make sure a token that should be a string or name is a string or name indeed. Avoid memory leak if a keyword has been already encountered and its value is overwritten. * freetype2/src/type1/t1load.c: (T1_FieldRec): Adjust invocations of T1_FIELD_XXX. (parse_dict): Ignore keywords that occur in the wrong dictionary (e.g., in Private instead of FontDict). * freetype2/src/type1/t1tokens.h: Adjust invocations of T1_FIELD_XXX.
Werner Lemberg 22ad9ef0 2005-05-09T22:11:36 Handle unsorted SFNT type 4 cmaps correctly (reported by Dirck Blaskey). * src/sfnt/ttcmap.h (TT_CMap): Add member `unsorted'. * src/sfnt/ttcmac.c: Use SFNT_Err_Ok where appropriate. (tt_cmap0_validate, tt_cmap2_validate, tt_cmap6_validate, tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate): Use `FT_Error' as return type. (tt_cmap4_validate): Use `FT_Error' as return type. Return error code for unsorted cmap. (tt_cmap4_char_index, tt_cmap4_char_next): Use old code for unsorted cmaps. (tt_face_build_cmaps): Set `unsorted' variable in cmap. Minor formatting.
David Turner 750fa961 2005-05-01T10:11:32 * Jamfile: removing otvalid from the list of compiled modules * include/freetype/internal/ftserv.h: added compiler pragmas to get rid of annoying warnings with Visual C++ compiler in maximum warning mode * src/autofit/afhints.c, src/autofit/aflatin.c, src/base/ftstroke.c, src/bdf/bdfdrivr.c, src/cache/ftcbasic.c, src/cache/ftccmap.c, src/cache/ftcmanag.c, src/cff/cffload.c, src/cid/cidload.c, src/lzw/zopen.c, src/otvalid/otvgdef.c, src/pcf/pcfread.c, src/sfnt/sfobjs.c, src/truetype/ttgxvar.c: removing compiler warnings
Werner Lemberg 023a4bf3 2004-10-14T11:33:04 * include/freetype/config/ftstdlib.h: Include `stddef.h'. (ft_ptrdiff_t): Define. * include/freetype/fttypes.h (FT_PtrDist): Use `ft_ptrdiff_t'. * src/cid/cidload.c (cid_parse_dict), src/type1/t1load.c (parse_dict): Fix compiler warning.
Werner Lemberg dfa46199 2004-03-05T09:26:24 * Jamfile, vms_make.com, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype/vcproj, include/freetype/ftmoderr.h: Add LZW module. * Jamfile.in: Removed. * docs/CHANGES: Updated. * include/freetype/internal/ftobjs.h: s/MIN/FT_MIN/, s/MAX/FT_MAX/, s/ABS/FT_ABS/. Updated all callers. * src/type1/t1load.c (parse_dict), src/pcf/pcfdrivr.c (PCF_Face_Init): Use FT_ERROR_BASE. Add support for PCF fonts compressed with LZW (extension .pcf.Z, created with `compress'). * include/freetype/config/ftoption.h, devel/ftoption.h (FT_CONFIG_OPTION_USE_LZW): New macro. * include/freetype/ftlzw.h: New file. * include/freetype/config/ftheader.h (FT_LZW_H): New macro for ftlzw.h. * src/lzw/*: New files. * src/pcf/pcfdrivr.c: Include FT_LZW_H.

Werner Lemberg 95867077 2004-02-12T08:33:20 * src/cid/cidload.c (cid_face_open): Always allocate face->cid_stream so that we can deallocate it safely. Make the PS parser more tolerant w.r.t. non-standard font data. In general, an error is only reported in case of a syntax error; a wrong type is now simply ignored (if possible). To be independent of the order of various MM-specific keywords, the parse_shared_dict routine has been removed -- the PS parser is now capable to skip this data. It no longer fails on parsing e.g. dup /WeightVector exch def Since the token following /WeightVector isn't `[' (starting an array) it is simply ignored. * include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a new internal error value. * src/type1/t1load.c (parse_blend_axis_types, parse_blend_design_positions, parse_blend_design_map): Return T1_Err_Ignore if no proper array is following the keyword. (parse_weight_vector): Use T1_ToTokenArray, initializing `blend' structure, if necessary. Return T1_Err_Ignore if no proper array is following the keyword. (parse_shared_dict): Removed. (parse_encoding): Set parser->root.error to return T1_Err_Ignore if no result can be obtained. Check for errors before accessing `elements' array. (t1_keywords): Remove /shareddict. (parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore. Set keyword_flag only in case of success. Check error code if skipping an unrecognized token. (T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend if blend commands haven't set up a proper MM font. * src/psaux/psobjs.c (ps_parser_load_field_table): Remove special code for synthetic fonts. Return PSaux_Err_Ignore if no proper value has been found.
Werner Lemberg ef512e3e 2004-01-23T19:52:40 Add support for the hexadicimal representation of binary data started with `StartData' in CID-keyed Type 1 fonts. * include/freetype/internal/t1types.h (CID_FaceRec): Add new members `binary_data' and `cid_stream'. * src/cid/cidload.c (cid_read_subrs): Use `face->cid_stream'. (cid_hex_to_binary): New auxiliary function. (cid_face_open): Add new argument `face_index' to return quickly if less than zero. Updated all callers. Call `cid_hex_to_binary', then open and assign memory stream to `face->cid_stream' if `parser->binary_length' is non-zero. * src/cid/cidload.h: Updated. * src/cid/cidobjs.c (cid_face_done): Free `binary_data' and `cid_stream'. * src/cid/cidparse.c (cid_parser_new): Check arguments to `StartData' and set parser->binary_length accordingly. * src/cid/cidparse.h (CID_Parser): New member `binary_length'. * src/cid/cidgload.c (cid_load_glyph): Use `face->cid_stream'. * docs/CHANGES: Updated. include/freetype/config/ftstdlib.h (ft_atoi): Replaced with... (ft_atol): This. * src/base/ftdbgmem.c: s/atol/ft_atol/. * src/type42/t42drivr.c: s/ft_atoi/ft_atol/.

Hints: (x) & -64 will warn if (x) is not signed.. use (x) & ~63 instead !
Werner Lemberg 52f911a1 2003-10-07T05:49:41 Heavy modification of the PS parser to handle comments and strings correctly.

David Turner b08fe2dc 2002-08-27T20:20:29 * massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
Werner Lemberg b3d5e9cf 2002-07-28T05:05:24 s/ft_memset/FT_MEM_SET/. s/FT_MEM_SET/FT_MEM_ZERO/ where appropriate.
Werner Lemberg 94ffae52 2002-04-14T00:54:32 * src/cff/cffgload.c (CFF_Parse_CharStrings): s/rand/Rand/ to avoid compiler warning. formatting/fixing ChangeLog
David Turner d15bc0d1 2002-04-12T09:31:48 * README.UNX: updated the Unix-specific quick-compilation guide to warn about the GNU Make requirement at compile time.. * include/freetype/config/ftstdlib.h, include/freetype/config/ftconfig.h, include/freetype/config/ftheader.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, src/autohint/ahoptim.c, src/base/ftdbgmem.c, src/base/ftdebug.c, src/base/ftmac.c, src/base/ftobjs.c, src/base/ftsystem.c, src/cache/ftcimage.c, src/cache/ftcsbits.c, src/cff/cffdriver.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cid/cidload.c, src/cid/cidparse.c, src/cid/cidriver.c, src/pcf/pcfdriver.c, src/pcf/pcfread.c, src/psaux/t1cmap.c, src/psaux/t1decode.c, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c, src/pshinter/pshrec.c, src/psnames/psmodule.c, src/raster/ftraster.c, src/sfnt/sfdriver.c, src/sfnt/ttload.c, src/sfnt/ttpost.c, src/smooth/ftgrays.c, src/type1/t1afm.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1load.c, src/type1/t1objs.c, src/type1/t1parse.c: added the new configuration file "ftstdlib.h" used to define aliases for all ISO C library functions used by the engine (e.g. strlen, qsort, setjmp, etc...) this eases the porting of FreeType 2 to exotic environments like XFree86 modules/extensions.. also removed many #include <string.h>, #include <stdlib.h>, etc... from the engine's sources where they're not needed..
Werner Lemberg 44be4d56 2002-03-30T17:08:04 formatting, copyright
David Turner e459d742 2002-03-22T13:52:37 * include/freetype/internal/ftmemory.h, and a lot of other files !!: changed the names of memory macros. Examples: MEM_Set => FT_MEM_SET MEM_Copy => FT_MEM_COPY MEM_Move => FT_MEM_MOVE ALLOC => FT_ALLOC FREE => FT_FREE REALLOC = >FT_REALLOC FT_NEW was introduced to allocate a new object from a _typed_ pointer.. note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer arguments. This results in _lots_ of sources being changed, but makes the code more generic and less error-prone..
David Turner 7d3a2642 2002-03-20T10:49:31 * renaming stream macros. Examples: FILE_Skip => FT_STREAM_SKIP FILE_Read => FT_STREAM_READ ACCESS_Frame => FT_FRAME_ENTER FORGET_Frame => FT_FRAME_EXIT etc...
David Turner 429978bd 2002-03-14T10:09:35 * include/freetype/internal/psaux.h, src/cid/cidload.c, src/cidtoken.h, src/psaux/psobjs.c, src/psaux/psobjs.h, src/psaux/t1decode.c, stc/type1/t1load.c, src/type1/t1tokens.h: updated common Postscript type definitions
David Turner bc82f1bb 2002-03-01T02:26:22 * include/freetype/ftconfig.h: changed FT_LOCAL xxxx to FT_LOCAL( xxxx ) everywhere in the source. Sames goes for FT_LOCAL_DEF xxxx translated into FT_LOCAL_DEF( xxxxx )
David Turner 29644179 2002-02-28T18:59:37 still more logical transformations. This time, some public API headers have been touched, while keeping everything backwards-compatible.. * include/freetype/t1tables.h: re-naming structure types. This done basically: typedef T1_Struct_ { } T1_Struct; becomes: typedef PS_StructRec_ { } PS_StructRec, *PS_Struct; typedef PS_StructRec T1_Struct; /* backwards-compatibility */ hence, we increase the coherency of the source code by effectuively using the 'Rec' prefix for structure types..
David Turner 4e7eeeec 2002-02-28T16:10:29 yet another logical transformation of the internals to make them more consistent and understandable.. mainly, changing things like PS_Table => PS_TableRec + *PS_Table
David Turner 3a664fca 2001-12-21T15:26:19 * src/cid/cidobjs.c (CID_Face_Done): fixed a memory leak, the subrs routines were never released when CID faces were destroyed
Werner Lemberg a560a1e0 2001-07-03T12:45:24 * src/autohint/ahhint.c (ah_hinter_align_weak_points): Remove unused variable `edges'. (ah_hinter_load): Remove unused variables `old_width' and `new_width'. * src/cid/cidload.c (cid_decrypt): Use `U' for constant (again). * src/psaux/psobjs.c (T1_Decrypt): Ditto. * src/type1/t1parse.c (T1_Get_Private_Dict): Ditto.

Werner Lemberg 1f7f0e87 2001-06-06T17:30:41 Complete redesign of error codes. Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed. Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets.

All internal error codes are now public; unused error codes have been removed, some are new. * include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro. All other source files have been updated to use the new error codes; some already existing (internal) error codes local to a module have been renamed to give them the same name as in the base module. All make files have been updated to include the local error files. * src/cid/cidtokens.h: Replaced with... * src/cid/cidtoken.h: This file for 8+3 consistency. * src/raster/ftraster.c: Use macros for header file names.
David Turner 09d55cea 2001-05-11T18:08:58 * src/cff/cffparse.c, src/cid/cidload.c, src/type1/t1load.c: fixed the incorrect EM size computation
David Turner 8d3a401f 2001-03-20T11:14:24 * builds/*/*-def.mk: changed the objects directory from "obj" to "objs" * include/freetype/config/ftheader.h: removed obsolete macros like FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that were previously defined in <freetype/ftcache.h>. Added comments to be included in a new API Reference section. * src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component needs to added its own directory to the include path at compile time. Modified all "rules.mk" and "descrip.mms" accordingly..
David Turner 3798110f 2001-03-19T11:34:49 fixed a small bug
David Turner 168e39a1 2001-03-17T23:25:34 small update to remove compiler warnings

Werner Lemberg 914b289f 2001-03-10T17:07:42 * src/*/*.c: Added many casts to make code more 64bit-safe.
David Turner 170c0d4c 2000-12-13T19:55:11 * include/freetype/config/ft2build.h, include/freetype/internal/internal.h: fixed header inclusion macros to use direct definitions. This is the only way to do these things in a portable way :-( The rest of the code should follow shortly though everything compiles now.. * builds/compiler/intelc.mk, builds/compiler/watcom.mk, builds/win32/detect.mk: added support for the Intel C/C++ compiler, as well as _preliminary_ (read: doesn't work !!) support for Watcom. Also added a new setup target. Type "make setup list" for a list of supported command-line compilers on Win32..
Werner Lemberg d5c1b27d 2000-12-12T22:28:12 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT): Removed. ANSI C doesn't (explicitly) allow macro expansion in arguments using `##'.

Werner Lemberg cc069beb 2000-12-08T16:17:16 cleanups
David Turner 19ed8afe 2000-12-08T02:42:29 - updated all source files to adhere to the new inclusion scheme - the CFF loader now loads the encodings and charset tables though doesn't use them for now
David Turner 76a5f623 2000-11-04T01:55:49 major reformatting of the sources: FT_EXPORT_DEF => FT_EXPORT FT_EXPORT_FUNC => FT_EXPORT_DEF BASE_DEF => FT_BASE BASE_FUNC => FT_BASE_DEF LOCAL_DEF => FT_LOCAL LOCAL_FUNC => FT_LOCAL_DEF LOCAL_FUNC_X => FT_CALLBACK_DEF LOCAL_DEF_X => FT_CALLBACK_TABLE FT_CPLUSPLUS => FT_CALLBACK_TABLE_DEF
Werner Lemberg e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
Werner Lemberg 6fbe4db6 2000-10-05T04:53:31 minor formatting issues
David Turner f00a4de9 2000-10-03T22:03:09 fixed two bugs: - one bug in the auto-hinter that could cause some program crashes with certain fonts - fixed the loading of the font matrix "offset" parameters in Type 1 and CID-keyed fonts..
Werner Lemberg 4e9dae68 2000-08-29T16:50:01 Introducing new macro LOCA_VAR to solve some problems with structures containing function pointers. FT will now compile again with C++.
Werner Lemberg d1b7475b 2000-08-24T16:29:15 Formatting, small fixes. Adding basic input parameter checking for exported functions.
David Turner 34f1c2f5 2000-08-23T22:47:44 finally, the CID and Type1z driver are finished !! Werner, please have a look at the code and start re-formatting it :-)
Werner Lemberg 29a90e26 2000-08-03T00:03:08 Updating unix/ftconfig.in to recent config/ftconfig.h changes. More C++ fixes: Introducing LOCAL_FUNC_X for local functions used in function pointers (there are no local anonymous functions in C++) and FT_CPLUSPLUS (instead of FT_EXPORT_VAR) to define linkage of structures which contain function pointers.
Werner Lemberg 35ca3426 2000-07-31T12:14:27 Fixing gcc warnings on Solaris.
Werner Lemberg a4367e08 2000-07-19T16:17:55 Formatting. Fixing documentation. Removing unused configuration macros.
Werner Lemberg 7fa51b55 2000-07-08T19:51:42 Formatting. Adding some trivial error checking. Adding/Fixing tracing levels.
David Turner a90663f5 2000-07-08T00:41:13 vast clean-up of the sources in order to allow flat directory compilation (by defining the FT_FLAT_COMPILE macro at compile time..) moved "freetype2/BUILD" to "freetype2/docs/BUILD"
David Turner 9b3d1c75 2000-07-07T19:47:34 - fixed a leak in the Type 1 driver - updated the CFF driver to support flex opcodes
Werner Lemberg bd5ae400 2000-07-05T04:32:02 Run g++ on the FreeType library. This should make the use of code in C++ programs easier: Renamed FT_WordXX to FT_UIntXX. Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType always accesses streams byte-wise, so this makes sense IMHO. Added a lot of #ifdef __cplusplus to header files (and removed a few). Other minor syntax fixes (mostly casts). Replaced the variable `private' with `private_dict' -- `private' is reserved in C++.
David Turner c6a92202 2000-07-04T18:12:13 various clean-ups: - using FT_UNUSED instead of UNUSED - using FT_LONG64 and FT_INT64 instead of LONG64 & INT64 - using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of... - removed the #ifdefs that used SIZEOF_INT, instead we now use FT_Int32 and FT_UInt32 when needed to support 32-bits quantity correctly on 64-bits systems..
Werner Lemberg ac39ecdc 2000-06-30T22:24:36 Formatting... Fixing incorrect scaling of vertical advance width.
Werner Lemberg deb4e983 2000-06-29T03:14:25 Formatting... Preprocessor lines now always start the line. Improved error handling in `base' module. Fixed a out-of-bounds error in ttgload.
