David Turner 9748807412 the psaux module is now nearly completed
the "type1z" driver uses it to parse Type 1 charstrings
(not to parse the Type 1 token stream yet though)..

Werner Lemberg 29a90e2610 Updating unix/ftconfig.in to recent config/ftconfig.h changes.
More C++ fixes: Introducing LOCAL_FUNC_X for local functions used in
function pointers (there are no local anonymous functions in C++) and
FT_CPLUSPLUS (instead of FT_EXPORT_VAR) to define linkage of structures
which contain function pointers.

Werner Lemberg 3a89c2a4ac Removing FT_MAKE_OPTION_SINGLE_LIBRARY_OBJECT. It has never worked.
Instead, define BASE_DEF() and BASE_FUNC() similarly to FT_EXPORT_DEF() and
FT_EXPORT_FUNC(), respectively, allowing the programmer to define proper
types and/or export lists for multiple DLLs if necessary (e.g. ftbase.dll --
standalone, fttype1.dll -- needs ftbase.dll, etc.).

The library is finally compiling and linking natively with a C++ compiler!

Werner Lemberg c713d924d8 Added #ifdef's for C++ to all header files. 2000-08-01 13:17:04 +00:00
Werner Lemberg e72c9fec17 Simplifying the FIELD_* and FRAME_* macros. Before calling these macros,
you should #define FT_STRUCTURE to the structure which will be filled.

Replaced FT_FIELD_REF with FT_FIELD_SIZE, FT_FIELD_SIZE_DELTA, and
FT_FIELD_OFFSET to make the code more readable; additionally, it should be
more portable because we no longer cast a pointer to an FT_UShort (which
e.g. fails with Sun's C++ compiler) but computes the difference between two
pointers which is guaranteed to work.

Fixing warnings (and C++ errors) while using Sun's latest cc and CC
incarnations.  Most of them are related to variable shadowing.

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++.

David Turner c6a92202c2 various clean-ups:
- using FT_UNUSED instead of UNUSED
- using FT_LONG64 and FT_INT64 instead of LONG64 & INT64
- using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of...

- 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..

David Turner f9ca2bb58a managed to re-design entirely the API in <freetype/ftglyph.h>
It is now really the "glyph factory" that Stefan was probably
dreaming about..

fixed some recent formatting errors from Werner ;-)

cleaned up the demonstration programs from most of the
rust that they had, though I'm sure someone is going to
re-format them really soon !!

"ftstring" now uses the new ftglyph.h API, and is now
faster and smaller.. yep..

David Turner c31286153a bugfixes in the Type1 drivers 2000-06-23 05:02:13 +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.

Werner Lemberg 9ca2af3838 A new formatting orgy.
Added some `#if 0' to completely disable the CID AFM stuff.  In case this is
not correct please fix.
2000-06-21 03:03:28 +00:00
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 :-)

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).

Werner Lemberg 1c0d4acb25 Fine-tuned a lot of tracing levels to make them more functional with ftview.
Added a lot of \n to tracing messages.

Fixed a serious bug in loading SBit offsets (missing parentheses around a
xxx ? yyy : zzz construct).

Replaced most GET_xxx() functions with calls to READ_Frame() in ttsbit.c
2000-06-06 20:41:48 +00:00
David Turner 04aa800ce9 added a CID-keyed font driver in "src/cid"
