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_.

Graham Asher 9eefed125a Simplified the incremental loading system for CFF fonts and fixed
a problem with the handling of the deprecated version of the Type 2
endchar command, that emulates Type 1 'seac'.
This version now works with the GhostScript-to-FreeType bridge
currently under development.

David Turner 5c0d3a4dca * src/base/ftobject.c, src/base/ftsynth.c, src/base/ftstroker.c,
src/bdf/bdfdrivr.c: removed compiler warnings
2002-08-22 20:35:36 +00:00
Werner Lemberg edbcbde703 Formatting. 2002-08-22 08:49:42 +00:00
Werner Lemberg ec810f8c6a * src/pshinter/pshalgo3.c (psh3_glyph_compute_inflections,
psh3_glyph_compute_extrema, psh3_hint_table_find_strong_point): Fix
compiler warnings and resolve shadowing of local variables.
2002-08-22 06:04:32 +00:00
David Turner 21f433cec9 * src/pshinter/pshalgo3.c, src/base/ftobjs.c, src/base/ftobject.c,
src/autohint/ahglyph.c, include/freetype/freetype.h: fixing typos
        and removing compiler warnings
2002-08-21 22:06:41 +00:00
David Turner f467e6a93f * include/freetype/freetype.h, src/base/ftobjs.c: changing the type
of the "load_flags" parameter of FT_Load_Glyph and FT_Load_Char from
        "FT_Int" to "FT_Int32", this in order to support more options.

        this should only break binary and/or source compatibility on
        16-bit platforms (Atari?)
2002-08-21 21:39:28 +00:00
David Turner a8199d608f * src/tools/docmaker/docmaker.py, src/tools/docmaker/utils.py,
src/tools/docmaker/tohtml.py: updating the DocMaker tool
2002-08-21 21:36:26 +00:00
David Turner 66456162af * src/pshinter/pshalgo3.c, src/autohint/ahangles.c,
src/autohint/ahangles.h, src/autohint/ahglyph.c, src/autohint/ahhint.c,
        src/autohint/ahtypes.h: the automatic and Postscript hinter now
        automatically detect inflection points in glyph outlines and treats
        them specially. This is very useful to prevent nasty effect like the
        disappearing diagonals of "S" and "s" in many, many fonts..
2002-08-21 21:34:59 +00:00
Werner Lemberg 215bf44438 * src/truetype/ttgload.c (TT_Get_Metrics): Add guard for k = 0. 2002-08-21 17:36:20 +00:00

horiBearingY.

* include/freetype/config/ftoption.h
(TT_CONFIG_OPTION_COMPONENT_OFFSET_SCALED): New macro.

* src/truetype/ttgload.c (OVERLAP_COMPOUND, SCALED_COMPONENT_OFFSET,
UNSCALED_COMPONENT_OFFSET): New macros for additional OpenType
glyph loading flags.
(load_truetype_glyph): Implement it.
2002-08-16 12:46:52 +00:00
Werner Lemberg f25ce9d0b3 * src/cff/cffgload.c (cff_free_glyph_data),
src/cff/cffload.c (cff_font_load): Use FT_UNUSED.

* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Initialize `error'.
* src/sfnt/sfobjs.c (SFNT_Load_Face): Fix compiler warning.
2002-08-15 23:07:18 +00:00
Graham Asher 824daa5881 Fixed compiler warnings about unreferenced formal parameters when
FT_CONFIG_OPTION_INCREMENTAL is not defined.

2002-08-06 21:47:40 +00:00
Graham Asher 733c255713 T1_Open_Face now tolerates a face with no charstrings if there is
an incremental loading interface. This is essential if incremental
loading of Type 1 fonts supplied by PostScript is to work.
2002-08-01 16:16:16 +00:00
Graham Asher ce12182cfc Modified incremental loading interface to be closer to David Turner's
preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.
2002-08-01 15:29:17 +00:00
David Turner f52165cc06 * src/tools/docmaker/*: adding new (more advanced) version of
the DocMaker tool. Python with regular expressions rocks..

Werner Lemberg bdb10748a7 * src/sfnt/ttload.c (sfnt_dir_check): Make it work with TTCs. 2002-07-27 22:51:28 +00:00
Werner Lemberg b94f3d3ea2 * src/pshinter/pshalgo3.c (psh3_hint_table_record,
psh3_hint_table_init, psh3_hint_table_activate_mask): Fix error
message.

Formatting.

without effect.
* src/truetype/ttdriver (Get_Char_Index, Get_Next_Char): Removed.
2002-07-26 09:09:10 +00:00
Graham Asher 11f0ab7d64 FIX for bug reported by Sven Neumann [sven@gimp.org] on the FreeType
development forum: "If FT_CONFIG_OPTION_INCREMENTAL is undefined
(this is the default), the TrueType loader crashes in line 852 of
src/truetype/ttgload.c when it tries to access face->glyph_locations.".
2002-07-24 13:58:21 +00:00
Graham Asher 320da730d4 More work on supporting fonts passed from GhostScript:
sfnt_dir_check now ignores the tables 'glyx' and 'locx' which are hacked-out
versions of 'glyf' and 'loca' in some PostScript Type 42 fonts, and will
generally be invalid.
2002-07-19 11:40:51 +00:00
Graham Asher bd8b08513f Added support for incrementally loaded Type 1 faces. 2002-07-18 16:57:43 +00:00
Graham Asher cd0d1dfa04 Changes to support incremental Type 42 fonts: assume a font has glyphs if it
has an incremental interface object.
2002-07-18 16:38:07 +00:00
Graham Asher ea94abb185 Added the incremental loading system for the CID driver.
Tested using my own unit test code.

Not implemented for any drivers yet.

David Turner 7acd73fd6a * src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttdriver.c: changing
the SFNT loader to check for SFNT-based font files differently. We now

    number instead.

* src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c
    (ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): changed the
    syntax of the FT2_DEBUG environment variable  used to control debugging
    output (i.e. logging and error messages). It must now look like:

       any:6 memory:4 io:3   or
       any:6,memory:4,io:3   or
