Ben Wagner 2fb8eda5d6 */*: Remove many function pointer casts.
In C it is undefined behavior to call a function through a function pointer
of a different type.  This is now detected by the Control Flow Integrity
Sanitizer.  All known issues have already been fixed.  Prevent any
accidental re-introduction by removing function pointer casts when defining
services.  The services will call the service functions through the function
pointers on the service.  As a result the functions must have the same type
so there should be no need to cast.  Removing the casts allows compilers to
warn about assignment to an incompatible function pointer type.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

Behdad Esfahbod 264b5e46c0 [raster] Handle `FT_RASTER_FLAG_AA' correctly.
This fixes a breakage caused by the commit `[raster] Remove
5-level gray AA mode from monochrome rasterizer.'.

Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de> and
octoploid <octoploid@yandex.com>.

* src/raster/ftraster.c (ft_black_render): Handle
`FT_RASTER_FLAG_AA'.

* src/raster/ftrend1.c (ft_raster1_render): Remove gray AA mode
remnants.

Chris Liddell 942aa5fff4 [raster] Fix Savannah bug #44022.
Add fallback for glyphs with degenerate bounding boxes.

If a glyph has only one very narrow feature, the bbox can end up
with either the width or height of the bbox being 0, in which case
no raster memory is allocated and no attempt is made to render the
glyph.  This is less than ideal when the drop-out compensation in
the rendering code would actually result in the glyph being
rendered.

This problem can be observed with the `I' glyph (gid 47) in the
Autodesk RomanS TrueType font.

* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
dimension is zero to explicitly round up/down (instead of simply
round).

Behdad Esfahbod 8dc8635874 [raster] Remove 5-level gray AA mode from monochrome rasterizer.
It was off by default and couldn't be turned on at runtime.  And the
smooth rasterizer superceded it over ten years ago.  No point in
keeping.  Comments suggested that it was there for compatibility
with FreeType 1.

550 lines down.

* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
RASTER_GRAY_LINES): Remove macros and all associated code.

(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
(black_TRaster): Remove `grays' and `gray_width'.

(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,

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.

Werner Lemberg 21bdca7907 [raster] Make bbox handling the same as with Microsoft's rasterizer.
Right before B/W rasterizing, the bbox gets simply rounded to
integers.  This fixes, for example, glyph `three' in font `Helvetica
Neue LT Com 65 Medium' at 11ppem.

Oran Agra 056095096f Position Independent Code (PIC) support in raster renderer.
* src/raster/ftrend1.h declare ft_raster1_renderer_class
and ft_raster5_renderer_class
using macros from ftrender.h,
when FT_CONFIG_OPTION_PIC is defined create and destroy
functions will be declared.
* src/smooth/ftrend1.c when FT_CONFIG_OPTION_PIC is defined
ft_raster1_renderer_class and ft_raster5_renderer_class structs
will have functions to init or create and destroy them
instead of being allocated in the global scope.
Macros will be used from rastpic.h in order to access
ft_standard_raster from the pic_container (allocated in ftraster.c).
In ft_raster1_render when PIC is enabled, the last letter of
module_name is used to verfy the renderer class rather than the
class pointer.

* src/raster/ftraster.c when FT_CONFIG_OPTION_PIC is defined
ft_standard_raster struct will have function to init it
instead of being allocated in the global scope.

New Files:
* src/raster/rastpic.h declare struct to hold PIC globals for raster
renderer and macros to access them.
* src/raster/rastpic.c implement functions to allocate, destroy and
initialize PIC globals for raster renderer.

* src/raster/raster.c add new file to build: rastpic.c.
* src/raster/jamfile add new files to FT2_MULTI build: rastpic.c.

David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
    transformations of the sources:

      - trying to convert all enums and constants to CAPITALIZED_STYLE, with
        #define definitions like

          #define  my_old_constants   MY_NEW_CONSTANT

      - big, big update of the documentation comments

    * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
    include/freetype/ftimage.h: adding support for LCD-optimized rendering
    though the new constants/enums:

      FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
      FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

    this is still work in progress, don't expect everything to work correctly
    though most of the features have been implemented.

    * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
    targets:

      FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
      FT_LOAD_TARGET_MONO   :: monochrome bitmaps
      FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated hinting & rendering
      FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated hinting & rendering

    note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
    behaviour of the font engine is _unchanged_.

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..
