David Turner fed59b7cc2 * src/sfnt/ttload.c (TT_Load_SFNT_Header): fixed a recent bug that prevented
OpenType fonts to be recognized by FreeType
2002-07-17 22:51:06 +00:00

Werner Lemberg 877ff67887 * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT
but FT_STREAM_READ.
Declare `stream' variable.

David Turner 791d83a612 * include/freetype/internal/tttypes.h, src/sfnt/ttload.c,
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
        fixing the SFNT name table loader to support various buggy fonts.
        it now ignores empty name entries, entries with invalid pointer
        offsets and certain fonts containing tables with broken "storageOffset"
        fields.

        name strings are now loaded on demand, which reduces the memory
        requirements for a given FT_Face tremendously (for example, the
        name table of Arial.ttf is about 10Kb and contains 70 names !!)

        finally, this is a _quick_ fix. The whole name table loader and
        interface will be rewritten in a much more cleanly way shortly,
        once CSEH have been introduced in the sources.

          src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
          src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h:

            updated the SFNT charmap support to use FT_CMaps
2002-03-22 15:02:38 +00:00
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            note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
            by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer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..

David Turner 28ea6f67c3 * src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),
src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
	that it accepts broken fonts like "foxjump.ttf", which made FreeType
	crash when trying to load them.

	Also improved the name table parser to be able to load
	Windows-encoded entries before Macintosh or Unicode ones, since it
	seems some fonts don't have reliable values here anyway.

David Turner bc82f1bbef * include/freetype/ftconfig.h: changed FT_LOCAL xxxx to FT_LOCAL( xxxx )

2001-04-02 23:54:01 +00:00
David Turner 6ce03efb12 * include/freetype/config/ftheader.h, include/freetype/ftsnames.h:
renamed "ftnames.h" to "ftsnames.h", and FT_NAMES_H to FT_SFNT_NAMES_H

	* docs/docmaker.py: added generation of INDEX link in table of contents
2001-03-20 14:50:04 +00:00
David Turner 8d3a401fa8 * builds/*/*-def.mk: changed the objects directory from "obj" to "objs"
* include/freetype/config/ftheader.h: removed obsolete macros like
	FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that
	were previously defined in <freetype/ftcache.h>. Added comments to be
	included in a new API Reference section.

	* src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component
	needs to added its own directory to the include path at compile time.
	Modified all "rules.mk" and "descrip.mms" accordingly..
2001-03-20 11:14:24 +00:00
David Turner 170c0d4c0d * include/freetype/config/ft2build.h,
include/freetype/internal/internal.h: fixed header inclusion macros
	to use direct definitions. This is the only way to do these things
	in a portable way :-( The rest of the code should follow shortly
	though everything compiles now..

	* builds/compiler/intelc.mk, builds/compiler/watcom.mk,
	builds/win32/detect.mk: added support for the Intel C/C++ compiler,
	as well as _preliminary_ (read: doesn't work !!) support for Watcom.
	Also added a new setup target. Type "make setup list" for a list
	of supported command-line compilers on Win32..
2000-12-13 19:55:11 +00:00
Werner Lemberg d5c1b27d58 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):
Removed.  ANSI C doesn't (explicitly) allow macro expansion in
arguments using `##'.
(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
names directly.  Make them configurable.  Use `##' to strip leading
and trailing spaces from arguments.

* builds/unix/ft2unix.h: Adapted.

* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,
ft_close_stream): Use FT_CALLBACK_DEF.

* builds/unix/ftsystem.c: Use new header scheme.
(FT_Done_Memory): Use free() from FT_Memory structure.

* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.

* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,
FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,
FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.

2000-11-07 06:30:29 +00:00
David Turner f96594faf0 integrated Yamano-Uchi changes to the base source code. However,
I've made a few modifications:

  - there is no new field named "driver" in "FT_SizeRec"

  - the new fields in "TT_SizeRec" are:

       strike_index   :: value 0xFFFF means "no sbit strike selected"
       strike_metrics :: the FT_Size_Metrics structure corresponding to
                         the currently selected strike

  - the code in "ttload.c" has been somewhat cleaned up too

thanks a lot, Y-U !!

Werner Lemberg 4a5c142a40 Minor fixes. 2000-08-29 18:37:25 +00:00
David Turner 5878a6d2ad a fix to the computation of the font "text height" (i.e. the
baseline-to-baseline distance).

Unfortunately, we cannot rely on the OS/2 fields, like
sTypoAscender or usWinAscent to compute it. Rather,
we only look at the horizontal header's content. In case
the "line gap" is set to 0, we compute the text height as
115% of the ascender+descender value..

(this percentage is based on the values found in many
Windows fonts).
2000-08-29 16:03:01 +00:00
Werner Lemberg 9a814fabbf Yamano-uchi added support for SFNT-wrapped CID bitmap font files (with

Werner Lemberg bd5ae40006 Run g++ on the FreeType library. This should make the use of code in
C++ programs easier:

  Renamed FT_WordXX to FT_UIntXX.

  Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType
  always accesses streams byte-wise, so this makes sense IMHO.

  Added a lot of #ifdef __cplusplus to header files (and removed a few).

  Other minor syntax fixes (mostly casts).

  Replaced the variable `private' with `private_dict' -- `private' is
  reserved in C++.
2000-07-05 04:32:02 +00:00
David Turner c6a92202c2 various clean-ups:

- removed the #ifdefs that used SIZEOF_INT, instead we now
  use FT_Int32 and FT_UInt32 when needed to support
  32-bits quantity correctly on 64-bits systems..
2000-07-04 18:12:13 +00:00

David Turner f0df85ba2a - MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
    source in order to provide the following enhancements:

      - more generic module support:

        The FT_Module type is now defined to represent a handle to a given
        module. The file <freetype/ftmodule.h> contains the FT_Module_Class
        definition, as well as the module-loading public API

        The FT_Driver type is still defined, and still represents a pointer
        to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
        FT_Get_Driver by FT_Get_Module, etc..


      - support for generic glyph image types:

        The FT_Renderer type is a pointer to a module used to perform various
        operations on glyph image.

        Each renderer is capable of handling images in a single format
        (e.g. ft_glyph_format_outline). Its functions are used to:

           - transform an glyph image
           - render a glyph image into a bitmap
           - return the control box (dimensions) of a given glyph image


        The scan converters "ftraster.c" and "ftgrays.c" have been moved
        to the new directory "src/renderer", and are used to provide two
        default renderer modules.

        One corresponds to the "standard" scan-converter, the other to the
        "smooth" one.

        The current renderer can be set through the new function
        FT_Set_Renderer.

        The old raster-related function FT_Set_Raster, FT_Get_Raster and
        FT_Set_Raster_Mode have now disappeared, in favor of the new:

           FT_Get_Renderer
           FT_Set_Renderer

        see the file <freetype/ftrender.h> for more details..

        These changes were necessary to properly support different scalable
        formats in the future, like bi-color glyphs, etc..


      - glyph loader object:

        A new internal object, called a 'glyph loader' has been introduced
        in the base layer. It is used by all scalable format font drivers
        to load glyphs and composites.

        This object has been created to reduce the code size of each driver,
        as each one of them basically re-implemented its functionality.

        See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
        more information..



      - FT_GlyphSlot had new fields:

        In order to support extended features (see below), the FT_GlyphSlot
        structure has a few new fields:

           linearHoriAdvance:  this field gives the linearly scaled (i.e.
                               scaled but unhinted) advance width for the glyph,
                               expressed as a 16.16 fixed pixel value. This
                               is useful to perform WYSIWYG text.

           linearVertAdvance:  this field gives the linearly scaled advance
                               height for the glyph (relevant in vertical glyph
                               layouts only). This is useful to perform
                               WYSIWYG text.

        Note that the two above field replace the removed "metrics2" field
        in the glyph slot.

           advance:   this field is a vector that gives the transformed
                      advance for the glyph. By default, it corresponds
                      to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
                      was specified when calling FT_Load_Glyph or FT_Load_Char

           bitmap_left: this field gives the distance in integer pixels from
                        the current pen position to the left-most pixel of
                        a glyph image WHEN IT IS A BITMAP. It is only valid
                        when the "format" field is set to
                        "ft_glyph_format_bitmap", for example, after calling
                        the new function FT_Render_Glyph.

           bitmap_top:  this field gives the distance in integer pixels from
                        the current pen position (located on the baseline) to
                        the top-most pixel of the glyph image WHEN IT IS A
                        BITMAP. Positive values correspond to upwards Y.

           loader:  this is a new private field for the glyph slot. Client
                    applications should not touch it..


      - support for transforms and direct rendering in FT_Load_Glyph:

        Most of the functionality found in <freetype/ftglyph.h> has been
        moved to the core library. Hence, the following:

          - a transform can be specified for a face through FT_Set_Transform.
            this transform is applied by FT_Load_Glyph to scalable glyph images
            (i.e. NOT TO BITMAPS) before the function returns, unless the
            bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..


          - once a glyph image has been loaded, it can be directly converted to
            a bitmap by using the new FT_Render_Glyph function. Note that this
            function takes the glyph image from the glyph slot, and converts
            it to a bitmap whose properties are returned in "face.glyph.bitmap",
            "face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
            native image might be lost after the conversion.


          - when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
            and FT_Load_Char functions will call FT_Render_Glyph automatically
            when needed.

David Turner f9b8dec437 major reformatting of the modules source code in order to get
rid of most of the basic types redefinitions (i.e. FT_Int instead
of "FT_Int", etc..)

The format-specific prefixs like "TT_", "T1_", "T2_" & 'CID_"
are now only used in relevant structures..

fixed Werner's fix to t2gload.c :-)
other small bug fixes

Werner Lemberg e35cac66c6 A complete revision of FreeType 2's GNU makefiles (of the library):
Tons of unnecessary stuff have been removed; only the essential rules
  have been retained.

  The source files now depend on all header files in include/freetype,
  include/freetype/config, and include/freetype/internal.  This is not
  optimal, I know, and I'll try to improve this, but it is better than
  before (namely no dependencies on `internal').

  FTDEBUG_SRC has been added (similar to FTSYS_SRC) -- I don't know
  exactly whether this is really useful, but it doesn't harm.

  There is now more documentation in the makefiles itself.

io-frames.html: Use of <th>, <code>, and <var> for better tagging.

Reactivating of FT_DEBUG_LEVEL_xxx macros.

Added a lot of #include directives to make `multi' builds possible -- note
that currently the modules cid, t1, and t1z have clashing structures and
functions which means that you can only use one of these three modules for a
multi build.

Added some missing function declarations to (local) header files.

Renamed some T1_Open_Face() to CID_Open_Face() in the cid module -- a lot
of other functions should be renamed also...

Replaced many FT_xxx stuff with T1_xxx in t1z driver -- this isn't finished
yet...

Fixed FT_Free() to allow a NULL pointer without an assertion (this has
always been a valid assumption in FreeType, at least in FT 1.x).

A lot of other, minor fixes (mostly documentation).

David Turner b1677a87ca changed the SFNT driver slightly to add more robust
checking based on the "search_rang", etc.., fields of
the sfnt header..

This avoids problems (like certain Type 1 multiple masters
incorrectly recognized as trueType files)..
