Werner Lemberg 913a365090 Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
test for a valid glyph index must be deferred to the font drivers.
This patch fixes Savannah bug #18301.

* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
(cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c
(pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),
src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
(FNT_Load_Glyph): Check validity of `glyph_index'.

David Turner 29c191cd53 * src/base/ftlcdfil.c: added support for FT_FORCE_LIGHT_LCD_FILTER
and FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros
      when building the library to change the default LCD filter to be
      used. This is only useful for experimentation

       the LCD filter, the FT_LcdFilter value is a enum describing
       which filter to apply, new values FT_LCD_FILTER_LIGHT and
       FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
       algorithm which produces incredible color fringes for everything
       except very-well hinted text)

       * src/autofit/aflatin.c: various tiny improvements that drastically
       improve the handling of serif fonts and of LCD/LCD_V hinting modes.

        added a new API to support color filtering of subpixel glyph

        returns FT_Err_Unimplemented_Feature; you need to #define
        FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile
        the real implementation

David Turner e3d6e94853 CHANGES BETWEEN 2.2.1 and 2.2.2
I. IMPORTANT BUG FIXES

    - Various integer overflows have been fixed.

    - PFB fonts with MacOS resource fork weren't  handled correctly on
      non-MacOS platforms.

    - The PCF font loarder has been seriously hardened against malformed
      font files.

  II. IMPORTANT CHANGES

    - the unpatented hinter is now part of the default build of the
      library, and we added code to automatically support "tricky"
      fonts that need it.

      what this means is that FreeType should "just work" with certain
      Asian fonts, like MingLiu, which cannot properly load without a
      bytecode interpreter, but fortunately do not use any of the
      patented bytecode opcodes.

      Note that the API didn't change, so you can still force
      unpatented hinting with a special parameter to FT_Open_Face
      as well.

      if you're an embedded systems developer, you might want to
      *disable* the feature to save code space by undefining
      TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h.

    - LCD-optimized rendering is now disabled in all default builds
      of the library, mainly due to patent reasons. For more information
      see:

      http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html

      a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has
      been introduced in ftoption.h; manually define it in this file
      if you want to re-enable the feature.

      the change only affects the implementation, not the FreeType API.
      This means that clients don't need to be modified, because the
      library still generates LCD decimated bitmaps, but with the added
      constraint that R=G=B on each triplet.

   - Some computation bugs in the TrueType bytecode interpreter were found,
     which allow us to get rid of very subtle and rare differences we had
     with the Windows renderer.

  III. MISCELLANEOUS

    - TrueType glyph loading is now about 25% faster.

    - the anti-aliased rasterizer has been optimized and is now 15% to 25%
      percent faster than the previous one, depending on content

    - the Type 1 loader has been improved; as an example, it now skips
      over top-level dictionaries properly

          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.

include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
    src/base/ftutil.c: udpating the memory management functions and
    macros to safely deal with array size buffer overflows, this
    corresponds to attemps to allocate arrays that are too large. For
    an example, consider the following code:

         count = read_uint32_from_file();
         array = malloc( sizeof(Item) * count );
         for ( nn = 0; nn < count; nn++ )
           array[nn] = read_item_from_file();

    if 'count' is larger than FT_UINT_MAX/sizeof(Item), the multiplication
    will overflow and the array allocated will be smaller than the data
    read from the file. In this case, the heap will be trashed, and this
    can be used as a denial-of-service, or make the engine crash later.

    the FT_ARRAY_NEW and FT_ARRAY_RENEW macro now check that the new
    count is no more than FT_INT_MAX/item_size, otherwise, a new error,
    named 'FT_Err_Array_Too_Large' will be returned.

    note that the memory debugger now works again when FT_DEBUG_MEMORY
    is defined, and FT_STRICT_ALIASING has disappeared, the corresponding
    code being now the default.

    Note that these files are not used by FreeType clients, all cache
    public APIs have been already moved to include/freetype/ftcache.h,
    and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it.

    the move is to allow us to modify the internals without intereference
    from rogue clients. Note that there are no known client that accesses
    the cache internals at the moment.

then exit.  Error handling or setting face->root is done later in

Wu, Chia-I (吳佳一) 65863a5712 Clean up the SFNT_Interface. In this pass, we want to treat the font
directory (offset table and table directory) as a normal table like
the others.  This also means that TTC is no longer recognized there,
but in `init_face'.

* include/freetype/internal/sfnt.h (SFNT_Interface),
src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
combined and renamed to `load_font_dir'.

* src/sfnt/ttload.h, src/sfnt/ttload.c:
s/sfnt_dir_check/check_table_dir/.
`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
and renamed to `tt_face_load_font_dir'.

* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
2006-02-14 07:01:29 +00:00
Wu, Chia-I (吳佳一) f5aa47beb0 Clean up the SFNT_Interface. Table loading functions are now named
after the tables' tags;  `hdmx' is TrueType-specific and thus the code
is moved to the truetype module; `get_metrics' is moved here from the
truetype module so that the code can be shared with the cff module.

This pass involves no real changes.  That is, the code is moved
verbatim mostly.  The only exception is the return value of
`tt_face_get_metrics'.

* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,
src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.

* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading
and parsing code is moved here.
Move `tt_face_get_metrics' here from the truetype module.  The return
value is changed from `void' to `FT_Error'.

* include/freetype/internal/fttrace.h: New trace: ttmtx.

* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
parsing code is moved here.
New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'.
`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

Werner Lemberg 59939244ad Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.

This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.

Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.

* modules.cfg: New file.

* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.

* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables.  Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.

* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files.  We no longer use make's `wildcard' function for this.

* Makefile (USE_MODULES): Remove.  Update all users.
(OBJ_DIR): Define it here.

* src/*/module.mk: Change

    make_module_list: foo
    foo: ...

to

    FTMODULE_H_COMMANDS += FOO
    define FOO
    ...
    endef

in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.

* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.

* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.

* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.

* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.

    * 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.

were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.

* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL.  That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching.  This was what we did and it
does cause some problems without rounding.

src/type1/t1gload.c, src/winfonts/winfnt.c: Fake the vertical metrics.
The fake metrics is monotone.

* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
formattings in vertical metrics faking.  There are still rooms for
improvements (and so do the CFF module).
2006-01-15 06:24:53 +00:00
Wu, Chia-I (吳佳一) e5ff059f7f * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdrivr.c
(PCF_Glyph_Load), src/winfonts/winfnt.c (FNT_Load_Glyph): Don't set
the linear advance fields as they are only for the outline glyphs.

* include/freetype/freetype.h: Documentation updates/clarificatoins.
The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
change need be made to the code.

* src/base/ftobjs.c (FT_Load_Glyph): Resolve flag dependencies and
decide whether to use the auto-hinter according to documentation.
There should to be no real difference.
Some checks (e.g., is text height positve?) after the glyph is loaded.
(FT_Select_Size, FT_Request_Size): Scales are set to wrong values.
Be careful that scales won't be negative.

2005-12-16 14:27:14 +00:00
David Turner db0182f056 small update 2005-12-14 21:16:33 +00:00
David Turner 89a2a4b531 * include/freetype/config/ftoption.h,
include/freetype/config/ftstdlib.h,
        include/freetype/internal/tttypes.h,
        src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c,
        src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:

        Added support for an embedded 'BDF ' table within SFNT-based
        bitmap font files. This is used to store atoms & properties from
        the original BDF fonts that were used to generate the font file.

        the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
        and is used to implement FT_Get_BDF_Property for these font files.

        At the moment, this is still experimental, the BDF table format isn't
        cast into stone yet.
2005-12-14 20:38:15 +00:00
David Turner 8def3c897f * Jamfile: small fix to ensure that ftexport.sym is placed in the
same location than other generated objects (i.e. within the 'objs'
        directory of the current dir)
2005-12-14 16:38:31 +00:00
David Turner 5b5f382b7d * src/autofit/aflatin.c, src/autofit/afhints.c: changed the
implementation of the LIGHT hinting mode to completely disable
        horizontal hinting. This is an experimental effort to integrate
        David Chester's latest patch without fucking the other hinting
        modes as well.

        Note that this doesn't force auto-hinting for all fonts however.
2005-12-14 16:37:15 +00:00
Werner Lemberg 364db0826b * src/sfnt/sfobjc.c (sfnt_init_face): Move tag check to...

Wu, Chia-I (吳佳一) a0911343ee Major update to distinguish between unsorted and overlapped segments
for cmap format 4.  For overlapped but sorted segments, which is
previously considered unsorted, we still use binary search.

* src/sfnt/ttcmap.h (struct  TT_CMapRec_): Replace `unsorted' by
`flags'.
(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.

* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
(struct TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
(tt_cmap4_reset): Removed.
(tt_cmap4_init): Updated accordingly.
(tt_cmap4_next): Updated accordingly.
Take care of overlapped segments.
(tt_cmap4_validate): Make sure the subtable is large enough.
Do not check glyph_ids because some fonts set the length wrongly.
Also, when all segments have offset 0, glyph_ids is always invalid. It
does not cause any problem so far only because the check misses
equality.
Distinguish between unsorted and overlapped segments.
(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to
do "charcode => glyph index" by linear/binary search.
(tt_cmap4_char_index, tt_cmap4_char_next): Use
tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
(tt_face_build_cmaps): Treat the return value of validator as flags
for cmap.
2005-11-29 11:32:53 +00:00
Wu, Chia-I (吳佳一) 569ec4ee2a * src/sfnt/ttcmap.c (struct TT_CMap12Rec_, tt_cmap12_init,
tt_cmap12_next): New struct/function for fast "next char".
(tt_cmap12_char_map_binary): New function to do "charcode => glyph
index" by binary search.
(tt_cmap12_char_index, tt_cmap12_char_next): Use
tt_cmap12_char_map_binary.
(tt_face_build_cmaps): Check table and offset correctly (equality is
missing).
