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.
Kan-Ru Chen 21b1a0de 2011-04-12T09:26:43 Fix reading of signed integers from files on 64bit platforms. Previously, signed integers were converted to unsigned integers, but this can fail because of sign extension. For example, 0xa344a1eb becomes 0xffffffffa344a1eb. We now do the reverse which is always correct because the integer size is the same during the cast from unsigned to signed. * include/freetype/internal/ftstream.h, src/base/ftstream.c (FT_Stream_Get*): Replace with... (FT_Stream_GetU*): Functions which read unsigned integers. Update all macros accordingly. * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.
Werner Lemberg 45a3c76b 2010-08-04T15:54:55 Fix Savannah bug #30644. * src/base/ftstream.c (FT_Stream_EnterFrame): Fix comparison.
Werner Lemberg 75787c19 2010-06-26T09:24:08 Add some memory checks (mainly for debugging). * src/base/ftstream.c (FT_Stream_EnterFrame): Exit with error if the frame size is larger than the stream size. * src/base/ftsystem.c (ft_ansi_stream_io): Exit with error if seeking a position larger than the stream size.
Su Yu efaf5abc 2009-08-03T19:55:58 Don't call `ft_fseek' every time when executing `ft_fread'. * src/base/ftstream.c (FT_Stream_Seek), src/base/ftsystem.c (ft_ansi_stream_io): Implement it.
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 c6788a38 2009-06-07T13:09:21 Fix some potential out-of-memory crashes. * src/base/ftobjs.c (ft_glyphslot_done): Check `slot->internal'. * src/base/ftstream.c (FT_Stream_ReleaseFrame): Check `stream'. * src/truetype/ttinterp.c (TT_New_Context): Avoid double-free of `exec' in case of failure.
Werner Lemberg 0a263a8b 2008-11-25T05:44:41 * src/base/ftstream.c (FT_Stream_ReadFields): Don't access stream before the NULL check. From Savannah patch #6681.
Werner Lemberg 7cb9ec0f 2008-06-09T20:49:29 * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and `private_len' unsigned. * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read it as such. (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned. * src/base/ftstream.c (FT_Stream_Skip): Reject negative values. * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis' for sane value. Fix typo. * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly. * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check `last_point'. * src/sfnt/ttload.c (tt_face_load_max_profile): Limit `maxTwilightPoints'.
Werner Lemberg c6afa122 2006-05-02T22:22:16 * include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++). (FT_ALLOC): Remove redundant redefinition. * builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use `-Wstrict-prototypes'. * src/base/ftstream.c (FT_Stream_EnterFrame): Add cast. Formatting, copyright years.
David Turner 9482ba50 2006-05-02T10:21:28 * include/freetype/ftstream.h, src/base/ftstream.c: modifying various frame-related functions to report the place where the frames were entered/extracted/exited/released in the memory debugger.
Werner Lemberg ebf5585d 2005-03-16T01:49:54 Formatting.
David Turner 68df4f73 2005-03-15T18:18:57 * src/bdf/bdflib.c: various improvements to the bdf loader, mainly used to reduce the amount of heap size required to only test wether we're dealing with a BDF font (the old code allocated 64 Kb right before any test). * src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check the LZW header before doing anything else. This helps avoid un-necessary heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !) * src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder, though the code savings is smaller.
Werner Lemberg 17439423 2004-08-11T05:25:37 * src/base/ftstream.c (FT_Stream_Close): Don't reset stream->close to NULL. This allows custom close functions to delete the FT_STREAM object. Add API to get information about SFNT tables. * include/freetype/internal/services/svsfnt.h (FT_SFNT_Table_Info_Func): New typedef. (SFNT_Table): Add it. * src/base/ftobjs (FT_Sfnt_Table_Info): New function. * include/freetype/tttables.h: Updated. * src/sfnt/sfdriver.c (sfnt_table_info): New function. (sfnt_service_sfnt_table): Add it. * docs/CHANGES: Updated. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 10. * builds/unix/configure.ac (version_info): Set to 9:8:3. * builds/unix/configure: Updated. * builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/. * builds/freetype.mk (refdoc), README, Jamfile (RefDoc): s/2.1.8/2.1.9/. * docs/CHANGES, docs/VERSION.DLL: Updated. * src/base/ftrfork.c (FT_Raccess_Guess) [!FT_CONFIG_OPTION_GUESSING_EMBEDDED_FORK]: Remove compiler warnings.

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..

Examples: NEXT_Byte => FT_NEXT_BYTE NEXT_Short => FT_NEXT_SHORT NEXT_UShortLE => FT_NEXT_USHORT_LE READ_Short => FT_READ_SHORT GET_Long => FT_GET_LONG etc.. also introduced the FT_PEEK_XXXX functions..
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...

(T1_Builder_FuncsRec): This. (T1_Builder_Funcs): New typedef. (PSAux_Interface): Remove compiler warnings. * src/psaux/psauxmod.c (t1_builder_funcs), src/psaux/psobjs.h (t1_builder_funcs): Updated. * src/pshinter/pshglob.h (PSH_Blue_Align): Replaced with ... (PSH_BLUE_ALIGN_{NONE,TOP,BOT}): New defines.

Werner Lemberg 415235df 2001-06-28T17:49:10 finishing function header formatting updating copyrights
Werner Lemberg f814d0fa 2001-06-27T16:18:10 First round in converting type foo ( ... ) to type foo ( ... ) Other minor formatting issues.
Werner Lemberg 8eb0353f 2001-06-19T23:03:41 Formatting.
David Turner 8edbcabc 2001-06-19T08:28:24 - updated doc for FT_New_Memory_Face - removed lots of compiler warnings in lint-style warning modes (/W4 with Visual C++)
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
Werner Lemberg 8ec9dfd9 2000-11-07T23:56:02 Moving doc comments for BASE functions from source to header files.
Werner Lemberg dc72aff4 2000-11-04T08:33:38 Finishing David's latest changes (there were some errors in it).
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 8bb45ec8 2000-09-29T06:41:56 Fixing comment in unixddef.mk which caused a trailing blank. Adding a new error, FT_Err_Invalid_Pixel_Size (used in winfnt.c) Fixing FT_Read_Fields() which failed for ft_frame_{bytes,skip}. This bug disabled the Winfont driver. Minor formatting issues.
David Turner e12e313a 2000-08-29T16:03:28 a small optimisation that should speed things a bit. I'm surprised I didn't do it before..
Werner Lemberg e72c9fec 2000-07-31T18:59:02 Simplifying the FIELD_* and FRAME_* macros. Before calling these macros, you should #define FT_STRUCTURE to the structure which will be filled. Replaced FT_FIELD_REF with FT_FIELD_SIZE, FT_FIELD_SIZE_DELTA, and FT_FIELD_OFFSET to make the code more readable; additionally, it should be more portable because we no longer cast a pointer to an FT_UShort (which e.g. fails with Sun's C++ compiler) but computes the difference between two pointers which is guaranteed to work. Fixing warnings (and C++ errors) while using Sun's latest cc and CC incarnations. Most of them are related to variable shadowing.
Werner Lemberg 7fa51b55 2000-07-08T19:51:42 Formatting. Adding some trivial error checking. Adding/Fixing tracing levels.
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 aa8c7da0 2000-07-04T03:37:18 Don't use -lefence in the demo Makefile. Added C++ guards in ftmodule.h Fix error check in ftglyph.c Formatting; adding copyrights; fixing documentation
David Turner d18388e4 2000-07-03T15:00:49 fixed a few 64-bit related bugs in "sfnt/ttload.c" and "base/ftstream.c" Note that "TT_PCLT" was incorrectly defined in <freetype/tttables.h>
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.
David Turner 81bb4ad9 2000-06-28T04:19:49 latest clean-ups.. The code compiles with NO WARNINGS with GCC and Visual C++ (also with LCC minus debugging options)
Werner Lemberg 61bd4b9d 2000-06-07T00:00:08 Added FT_FRAME_SKIP_xxx to skip fields. More use of READ_Fields() in ttsbit.c Other minor fixes.
Werner Lemberg 1c0d4acb 2000-06-06T20:41:48 Fine-tuned a lot of tracing levels to make them more functional with ftview. Added a lot of \n to tracing messages. Fixed a serious bug in loading SBit offsets (missing parentheses around a xxx ? yyy : zzz construct). Replaced most GET_xxx() functions with calls to READ_Frame() in ttsbit.c
Werner Lemberg 4e6dd858 2000-06-05T05:26:15 freetype.h: Adding ft_encoding_xxx values for some CJK encodings. Fixing copyright notice on many files. Changed some tracing levels. A lot of formatting, fixing documentation etc. as usual.
Werner Lemberg eb81e378 2000-06-03T06:03:11 More preparation for tracing. Formatting.
Werner Lemberg 9a754ce3 2000-06-02T21:31:32 Formatting; adding some tracing code.
Werner Lemberg 91e52d41 2000-06-02T14:30:38 Finishing first formatting/documenting etc. of the `base' dir. Some modules are still badly documented, though...
David Turner 2e421319 2000-05-26T22:13:17 moved a lot of things from the TrueType driver to the SFNT module (whose interface has changed, by the way) This allows even more code re-use between TrueType and OpenType formats..
David Turner e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
David Turner bfe2f98f 2000-05-12T12:17:15 a new massive grunt work. Redefined the EXPORT_DEF, EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to let them take an argument.. This is needed to compile the library as a DLL on some platforms that have different compiler conventions..
David Turner efce08d6 2000-05-11T18:23:52 major re-organisation of the FreeType 2 directory hierarchy
David Turner 33ec7d47 2000-05-02T10:51:04 removed an over-zealous assertation that halted the engine with a few weird fonts.
Just van Rossum 59d8ac46 2000-03-05T15:59:09 formatting: some tabs replaced by spaces
David Turner 818336fd 2000-02-13T13:36:53 Added the function FT_Read_Fields, it acts as a finite-state automata to load large TrueType tables in object structures. This is experimental, don't mess too much with it, thanks :-)
David Turner fdc225b1 2000-01-17T11:21:49 fixed another small bug in the FT_Read_xxxx functions (they didn't updated the stream position in the case of disk-based streams. This went un-noticed under Linux which uses memory-mapped files by default)
Werner Lemberg 7880dd66 2000-01-10T17:19:45 ftcalc.c, ftextend.c, ftoutln.c, ftraster.c, ftstream.c: Removing trailing spaces. ftlist.h: Removing duplicated documentation (which is in ftlist.c also). ftinit.c, ftlist.c, ftobjs.c: Formatting, adding documentation.
David Turner d2b1f357 1999-12-16T23:11:37 Initial revision
