suzuki toshiya c7c4d68bfb [raccess] Modify for PIC build.
Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html

Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
are renamed with `ft_' suffixes.

* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
to `ft_raccess_rule_by_darwin_vfs()'.
* src/base/ftobjs.c: Ditto.

* src/base/ftrfork.c: Declarations of FT_RFork_Rule,
raccess_guess_rec, are moved to...
* include/freetype/internal/ftrfork.h: Here.

* include/freetype/internal/ftrfork.h:
FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
to replace raccess_guess_table[] in both of PIC and non-PIC
modes.
* src/base/ftrfork.c: raccess_guess_table[] array is rewritten
by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.

* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
storage.  (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
the function pointer from `ft_raccess_guess_table' storage in
`BasePIC' structure.
* src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
FT_RACCESS_GUESS_TABLE_GET.
(raccess_get_rule_type_from_rule_index): Add `library' as the
first argument to the function, to retrieve the storage of
`ft_raccess_guess_table' from it.  Also `raccess_guess_table'
is replaced by FT_RACCESS_GUESS_TABLE_GET.
(ft_raccess_rule_by_darwin_vfs): Ditto.

suzuki toshiya 1749d8bc6a Remove trailing spaces. 2012-01-17 02:00:24 +09:00
suzuki toshiya 3c96681856 Fix redundant declaration warning in PIC mode.
Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
designed to declare xxx_pic_{free,init} by themselves.
Because these macros are used at the end of the module
interface (e.g. ttdriver.c) and the wrapper source to build
a module as a single object (e.g. truetype.c) includes
the PIC file (e.g. ttpic.c) before the module interface,
these macros are expanded AFTER xxx_pic_{free,init} body
when the modules are built as single object.
The declaration after the implementation causes the redundant
declaration warnings, so the declarations are moved to module
PIC headers (e.g. ttpic.h).  Separating to other header files
are needed for multi build.

* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
Remove class_##_pic_free and class_##_pic_init declarations.
* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
FT_DEFINE_MODULE): Ditto.

* src/base/basepic.h: Insert a comment and fix coding style.
* src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
init}.
* src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
init}.

ft_raster{1,5}_renderer_class_pic_{free,init}
* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.

suzuki toshiya 714ee56ab1 [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
was a configurable macro to disable Carbon-dependent code.  Because
now configure script sets DARWIN_NO_CARBON by default and disables
Darwin & Carbon-dependent codes, these macros can be unified.
FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
(defined by default) is removed, because DARWIN_NO_CARBON violates
FT_XXX naming convention of public macros, and a macro configured by
default is not portable for the building without configure (e.g.
make devel).

* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
old Mac font support is requested and Carbon is available.
* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is
requested.
* include/freetype/config/ftconfig.in: Ditto.
* builds/vms/ftconfig.h: Ditto.

* src/base/ftbase.h: Remove DARWIN_NO_CARBON.
* src/base/ftbase.c: Ditto.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Ditto.

* src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
(same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
* builds/mac/ftmac.c: Ditto.

* builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
* builds/mac/FreeType.m68k_far.make.txt: Ditto.
* builds/mac/FreeType.ppc_classic.make.txt: Ditto.

David Bevan aecbfe1ba7 [ftstroke] Major revision.
The main problems
-----------------

  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
    joins (not bevel joins) were generated.  Indeed, the meanings of
    `miter' and `bevel' were incorrectly reversed (consistently) in
    both the code and comments.

  o The way bevel joins were constructed (whether specified
    explicitly, or created as a result of exceeding the miter limit)
    did not match what is required for stroked text in PostScript or
    PDF.

The main fixes
--------------

  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
    introduced to support PostScript and PDF miter joins.

  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
    alias for FT_STROKER_LINEJOIN_MITER.

Additionally, a variety of stroking errors have been fixed.  These
would cause various artifacts (including points `at infinity'),
especially when stroking poor quality fonts.

See

  http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html

for example documents.  The FreeType stroker now produces results
very similar to that produced by GhostScript and Distiller for these
fonts.

Other problems
--------------

The following problems have been resolved:

  o Inside corners could be generated incorrectly.  Intersecting the
    inside corner could cause a missing triangular area and other
    effects.

    The intersection point can only be used if the join is between
    two lines and both lines are long enough.  The `optimization'
    condition in `ft_stroker_inside' has been corrected; this
    requires the line length to be passed into various functions and
    stored in `FT_StrokerRec'.

  o Incorrect cubic curves could be generated.  The angle
    calculations in `FT_Stroker_CubicTo' have been corrected to
    handle the case of the curve crossing the +/-PI direction.

  o If the border radius was greater than the radius of curvature of
    a curve, then the negative sector would end up outside (not
    inside) the border.  This situation is now recognized and the
    negative sector is circumnavigated in the opposite direction.
    (If round line joins are being used, this code is disabled
    because the line join will always cover the negative sector.)

  o When a curve is split, the arcs may not join smoothly (especially
    if the curve turns sharply back on itself).  Changes in
    direction between adjacent arcs were not handled.  A round
    corner is now added if the deviation from one arc to the next is
    greater than a suitable threshold.

  o The current direction wasn't retained if a the outline contained
    a zero length lineto or a curve that was determined to be
    `basically a point'.  This could cause a spurious join to be
    added.

  o Cubics with close control points could be mishandled.  All eight
    cases are now distinguished correctly.

Other improvements
------------------

o Borders for cubic curves could be too `flat'.
  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
  this.

o The handling and use of movable points has been simplified a
  little.

o Various values are now computed only if the results are actually
  needed.

o The directions of the outer and inner borders have been swapped,
  as recommended by Graham Asher.

Behdad Esfahbod 8c82ec5b17 Always ignore global advance.
This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
deprecated, and ignored.  The new behavior is what every major user
of FreeType has been requesting.  Global advance is broken in many
CJK fonts.  Just ignoring it by default makes most sense.

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.

Ken Sharp 980b76ea5e Really fix Savannah bug #28678 (part 1).
After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only.  For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction.  Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).

* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.

Ralph Giles 17904a107a Document that FT_Get_X11_Font_Format() is a general call.
This function was originally added to return the underlying font
format in a way which was compatible with the needs of the XFree86
font server.  However, a function of this sort is also necessary when
freetype is used by PDF interpreters which apply different rules
based on the font format.

The X11 namespace is confusing for such users.  This commit ameliorates
that confusion by documenting that this function is in fact entirely
internal to freetype and doesn't depend on X11 in any way.

Werner Lemberg 11cb8c36ed Use 16.16 format while parsing Type 1 charstrings.
This fixes Savannah bug #26867.

Previously, only integers have been used which can lead to serious
rounding errors.

However, fractional values are only used internally; after the
charstrings (of either Type 1 or 2) have been processed, the
resulting coordinates get rounded to integers currently -- before
applying scaling.  This should be fixed; at the same time a new load
flag should be introduced, to be used in combination with
FT_LOAD_NO_SCALE, which indicates that font units are returned in
16.16 format.  Similarly, the incremental interface should be
extended to allow fractional values for metrics.

* include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift'
field.
* include/freetype/internal/pshints.h (T1_Hints_SetStemFunc,
T1_Hints_SetStem3Func): Use FT_Fixed for coordinates.

* src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H.
(t1_build_add_point): Always convert fixed to integer.
* src/psaux/t1decode.c (t1_decoder_parse_charstrings):

`div').
[CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate

Werner Lemberg 7227114043 Fix B/W rasterization of subglyphs with different drop-out modes.
Normally, the SCANMODE instruction (if present) to set the drop-out
mode in a TrueType font is located in the `prep' table only and thus
valid for all glyphs.  However, there are fonts like `pala.ttf'
which additionally contain this instruction in the hinting code of
some glyphs (but not all).  As a result it can happen that a
composite glyph needs multiple drop-out modes for its subglyphs
since the rendering state gets reset for each subglyph.

FreeType collects the hinted outlines from all subglyphs, then it
sends the data to the rasterizer.  It also sends the drop-out mode
-- after hinting has been applied -- and here is the error: It sends
the drop-out mode of the last subglyph only; drop-out modes of all
other subglyphs are lost.

This patch fixes the problem; it adds a second, alternative
mechanism to pass the drop-out mode: For each contour, the
rasterizer now checks the first `tags' array element.  If bit 2 is
set, bits 5-7 contain the contour's drop-out mode, overriding the
global drop-out mode.

* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.

* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
`tags[0]'.

* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
Use bits 3-5 instead of 0-2.
(New_Profile): Set the drop-out mode in the profile's `flags' field.
(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
necessary.
(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
mode.

Werner Lemberg ce33a312da FT_USE_MODULE declares things as:
extern const FT_Module_Class

(or similar for C++).  However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.

To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:

  All declarations that refer to the same object or function shall
  have compatible type; otherwise, the behavior is undefined.

(And they are not compatible types.)

Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does.  (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

Patch from Savannah bug #25133.

* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

* builds/amiga/include/freetype/config/ftmodule.h,

Werner Lemberg b972a2a294 Generalize the concept of `tricky' fonts by introducing
FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
engine is necessary for correct rendering.

At the same time, slightly modify the behaviour of tricky fonts:
FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
FT_LOAD_NO_AUTOHINT must be used.

Finally, tricky TrueType fonts always use the bytecode interpreter
even if the patented code is used.

* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
New macros.

* src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
semantics as described above.

* src/truetype/ttobjs.c (tt_check_trickyness): New function, using
code of ...
(tt_face_init): This function, now simplified and updated to new
semantics.

* src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
fonts.

bug #25010.

outlines nor bitmaps.

* src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there

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

          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.

David Turner 9ca782569c * include/freetype/internal/ftmemory.h, src/base/ftbitmap.c,

    src/raster/ftrend1.c, src/sfnt/ttpost.c, src/truetype/ttgxvar.c,
    src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
    against out-of-bounds conditions when allocating arrays. This is
    for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
    already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
    macros.
2006-05-02 09:00:29 +00:00
David Turner 264f307e66 * include/freetype/fterrdef.h, include/freetype/config/ftconfig.h,
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.
