Kan-Ru Chen 21b1a0de7c 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.

2010-08-04 15:54:55 +02:00
Werner Lemberg 75787c19ea 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.
2010-06-26 09:24:08 +02:00
Su Yu efaf5abcf8 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.
2009-08-03 19:55:58 +02:00
Werner Lemberg 858abbedc0 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 c6afa1221a * include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++).
(FT_ALLOC): Remove redundant redefinition.

David Turner 9482ba50b7 * include/freetype/ftstream.h, src/base/ftstream.c: modifying

    frames were entered/extracted/exited/released in the memory debugger.

David Turner 68df4f732d * 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.
2005-03-15 18:18:57 +00:00
Werner Lemberg 17439423f8 * src/base/ftstream.c (FT_Stream_Close): Don't reset stream->close

David Turner e459d742e6 * 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..

              NEXT_UShortLE => FT_NEXT_USHORT_LE

              GET_Long      => FT_GET_LONG
              etc..

            also introduced the FT_PEEK_XXXX functions..

           FORGET_Frame => FT_FRAME_EXIT

          FT_New_Stream( filename, stream ) =>
            FT_Stream_Open( stream, filename )

          (the function doesn't create the FT_Stream structure, it simply

          "include/freetype/ftsystem.h" have also been changed without
          problems:

Werner Lemberg e72c9fec17 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

  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++.
