Andrew Church 67cf7a8841 Fix Savannah bug #39266.
If memory allocations fail at certain points while opening a font,
FreeType can either crash due to a NULL dereference or leak memory.

* include/freetype/internal/ftobjs.c (FT_Face_InternalRec,
FT_LibraryRec): Make `refcount' a signed integer.  If, for example,
FT_Open_Face() fails in a memory allocation before the face's
reference count is set to 1, a subsequent `FT_Done_Library' call
would otherwise loop over `FT_Done_Face' 2^32 times before freeing
the face.

* src/base/ftobjs.c (open_face): Initialize `stream' and friends
earlier.
(FT_Open_Face) <Fail>: Behave correctly if `node' is NULL.
(FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.

Behdad Esfahbod 760d342d37 Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification

  https://color-emoji.googlecode.com/git/specification/v1.html

which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images.  If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.

Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Werner Lemberg 06474c3e5b [cff] Add a new Type 2 interpreter and hinter.
This work, written by Dave Arnold <darnold@adobe.com> and fully
integrated into FreeType by me, is a donation by Adobe in
collaboration with Google.  It is vastly superior to the old CFF
engine, and it will replace it soon.  Right now, it is still off by
default, and you have to explicitly select it using the new
`hinting-engine' property of the cff driver.

For convenience, (most of) the new files are committed separately.

* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
* include/freetype/ftcffdrv.h: New file to access CFF driver
properties.

* src/cff/cff.c: Include new files.
* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
`hinting-engine' and `no-stem-darkening' properties (only the Adobe
engine listens to them).
* src/cff/cffgload.c: Include `cf2ft.h'.
(cff_decoder_prepare): Initialize `current_subfont'.
(cff_build_add_point): Handle Adobe engine which uses 16.16
coordinates.
(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
separately.
Choose rendering engine based on `hinting_engine' property.
* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
engine.

Werner Lemberg c58ce3beee Introduce `FT_THROW' macro.
The idea is to replace code like

  return FT_Err_Foo_Bar;

or

  return CFF_Err_Foo_Bar;

with

  return FT_THROW( Foo_Bar );

The FT_THROW macro has two functions:

  . It hides the module specific prefix.

  . In debug mode, it calls the empty function `FT_Throw' which can
    be thus used to set a breakpoint.

Werner Lemberg a9f6f85e77 Various compiler warning fixes.
* include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use

it 32bit or 64bit or whatever), while a negative integer has not
this flexibility.

Infinality ed6508c41a [truetype] Remove unused rounding functionality. 2012-06-26 17:20:27 -05:00
Infinality 79e36baebb [truetype] Support subpixel hinting.
This is the large, famous `Infinality' patch to support ClearType
bytecode which has been available from
http://www.infinality.net/blog/ for some time, and which has been
refined over the last years.  While still experimental, it is now
mature enough to be included directly into FreeType.

Most of the code is based on the ClearType whitepaper written by
Greg Hitchcock

  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

which gives a detailed overview of the necessary changes to the
Microsoft rasterizer so that older fonts are supported.  However, a
lot of details are still missing, and this patches provides a
framework to easily handle rendering issues down to the glyph level
of certain fonts.

Note that ClearType support is not completely implemented!  In
particular, full support for the options `compatible_widths',
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
instruction) is missing.

* src/truetype/ttsubpix.c: New file, providing code to handle
`tweaks', this is, rules for certain glyphs in certain fonts
(including wildcards) which need a special treatment.

* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

* include/freetype/config/ftoption.h, src/devel/ftoption.h
(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,
FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include
`ttsubpix.c'.

* src/truetype/ttgload.c: Include `ttsubpix.h'.
[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(tt_get_metrics): Set tweak flags.
(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
(TT_Process_Simple_Glyph): Compensate emboldening if necessary.
(compute_glyph_metrics): Handle `compatible widths' option.
(tt_loader_init): Handle ClearType GETINFO information bits.

* src/truetype/rules.mk (TT_DRC_SRC): Updated.

* src/truetype/ttinterp.c: Include `ttsubpix.h'.
[Where necessary, changes below are guarded by
TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(Direct_Move, Direct_Move_X): Extended.
(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,
Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45,

(Ins_IUP, Ins_DELTAP): Handle tweaks.
(Ins_GETINFO): Handle new ClearType bits.
(TT_RunIns): Handle tweaks.

* src/truetype/ttinterp.h: Updated.

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.

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):

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.

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.

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):
Use 16.16 format everywhere (except for large integers followed by a
`div').
[CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate
code uncoditionally.
Add support for random numbers and update remaining code
accordingly; this should work now.
(t1_operator_seac): Updated.
* src/psaux/pshrec.c: Include FT_INTERNAL_CALC_H.
(ps_hints_t1stem3, t1_hints_stem): Updated.

* src/cid/cidgload.c: Include FT_INTERNAL_CALC_H.
(cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL],
(cid_face_compute_max_advance, cid_slot_load_glyph): Updated.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String)
[FT_CONFIG_OPTION_INCREMENTAL], (T1_Get_Advances, T1_Load_Glyph):
Updated.
* src/type1/t1load.c: Include FT_INTERNAL_CALC_H.
* src/type1/t1objs.c (T1_Face_Init): Updated.
