Werner Lemberg e40e8b33a1 [gzip] Fix access of small compressed files (#45937).
* src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak.

(ft_gzip_get_uncompressed_file): Correct byte order while reading
unsigned long value.  Without this change, the whole optimization of
accessing small files in `FT_Stream_OpenGzip' is never executed!  As
a consequence, access to PCF files in general (which are normally
small files) should be much improved now as originally intended.

Werner Lemberg e3c9301581 */*: Use FT_Err_Ok only.
This is a purely mechanical conversion.
2013-03-14 11:21:17 +01:00
Werner Lemberg 059bc335ce */*: 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 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.

        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

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.

Werner Lemberg 779afe4b91 * src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.

* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.


Synchronize computation of height and width for bitmap strikes.  The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes.  The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.

* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

* src/pshinter/pshalgo3.c (ps3_hints_apply): Check whether we
actually have an outline.
2003-05-20 22:06:38 +00:00
Werner Lemberg 428c2e4f62 * src/bdf/bdflib.c (hash_bucket, hash_lookup): Use `const' for first
argument.
(bdf_get_font_property): Use `const' for third argument.
Updated all callers.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
similar to the PCF driver.
* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
Updated.

* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
is declared twice.  It is perhaps better to modify the zlip source
files directly instead of this hack.
(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
to make build with g++ successful.
2003-04-25 05:35:04 +00:00
Werner Lemberg 917a593780 * src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]:
Convert K&R format to modern C usage.
(FT_Stream_OpenGzip): Use long constant.

Cleanups.

David Turner a3c378024b * src/gzip/ftgzip.c (ft_gzip_file_done): fixed memory leak, the ZLib
stream was not properly finalized
2003-02-28 08:32:46 +00:00
David Turner 229d122e92 * src/gzip/ftgzip.c: fixed a bug that caused FreeType to loop endlessly
when trying to read certain compressed gzip files. The following test
    could be used to reveal the bug:

       touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz


    * src/pfr/pfrobjs.c, src/pfr/pfrload.c, src/pfr/pfrtypes.h: several
    fixes to the PFR font driver:

      - the list of available embedded bitmaps was not correctly set
        in the root FT_FaceRec structure describing the face

      - the glyph loader always tried to load the outlines when
        FT_LOAD_SBITS_ONLY was specified

      - the table loaded now scans for *undocumented* elements of a
        physical font's auxiliary data record, this is necessary to
        retrieve the "real" family and style names.

        NOTE THAT THIS CHANGES THE FAMILY NAME OF MANY PFR FONTS !!

David Turner 4bdf4350f2 various improvements for 2.1.4. see ChangeLog, I've got problems with
copy & paste on my desktop !!
2003-01-30 23:24:18 +00:00
David Turner 619d62d933 * src/gzip/ftgzip.c: bugfix: couldn't read certain gzip-ed font files 2003-01-15 23:01:02 +00:00
David Turner 621e488622 2002-12-16 David Turner <david@freetype.org>
* docs/VERSION.DLL: updating document to better explain the differences between
        the three version numbers being used on Unix, as well as provide the AutoConf
        fragment provided by Lars Clausen

        * src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
        prevented bezier arcs with negative vertical coordinates to be rendered
        appropriately


2002-11-27  Vincent Caron <v.caron@zerodeux.net>

        * builds/unix/unix-def.in, builds/unix/freetype-config.in,
        builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
        adding support for system zlib installations when available on the
        target platform (Unix only)
2002-12-16 21:51:24 +00:00
David Turner 60b32e16e7 2002-11-05 David Turner <david@freetype.org>
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
        support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
        the use of system-wide zlib.

        Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
        is not #undef-ed anymore. This allows the build system to define them
        depending on the configuration (typically by adding -D flags at
        compile time).

        * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
        in optimized mode relative to the "volatile" local variables. This was
        not a compiler bug after all, but the fact that a pointer to a volatile
        variable is not the same than a volatile pointer to a variable :-)

        the fix was to change  "volatile FT_Byte*  p"
        into                   "FT_Byte* volatile  p"

        * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
        compiler warnings in optimized modes

        * src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
        any zlib function names outside of the component. This prevents linking
        problems on some platforms, when applications want to link FreeType
        _and_ ZLib together.


2002-11-05  Juliusz  <jch@pps.jussieu.fr>

        * src/psaux/psobjs.c (ps_table_add): modified increment loop in
        order to implement exponential behaviour
2002-11-06 22:32:54 +00:00
David Turner 54b0bca50c * include/freetype/ftgzip.h, src/gzip/ftgzip.c:
adding support for gzip compressed streams !!

        * src/pcf/pcfdriver.c: adding automatic support for gzip-compressed
        PCF files
