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 !!

- David

David Turner c5cdf8bcf1 re-adding a "unix-dev.mk". Debugging libtool output
is just too much of a pain for me, I prefer a good old
static lib without optimizations :-)

"make devel" is back on Unix then..

Werner Lemberg 321cd27d0f Removing compiler warnings about unused portions of code.
Now unix.in uses absolute paths also to overcome problems with libtool.
To do that in a consistent way I had to modify the rules how to handle
$OBJ_DIR (and consequently $LIB_DIR): You should set $OBJ_DIR explicitly
on the command line (or environment).

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 78575dc0d1 A lot of formatting.
Added more tracing levels.

More Makefile fixes.

Minor other changes.

Werner Lemberg e1d5dd78f4 Moved all *errors.h header files to include/freetype/internal for
consistency.

Removed unused error message.

David Turner e49ab25c08 formatting - removed trailing spaces 2000-05-16 23:44:38 +00:00
David Turner 4f2c5544bb additional changes, this time in order to pass extra parameters
to font drivers when creating a new face object.

The FT_Open_Args structure has been changed to simplify
its use and allow generic parameters too..

David Turner efce08d67c major re-organisation of the FreeType 2 directory hierarchy 2000-05-11 18:23:52 +00:00
David Turner 7f7aadf4f7 finished moving all configuration macros to
"config/ftoption.h"
2000-03-13 12:57:27 +00:00
David Turner 08fdac980a fixed a bug in the glyph loader that caused a memory
block to be freed twice. Also performed changes to use
the new glyph zone object that has appeared in ftobjs.h
2000-02-21 16:01:33 +00:00
David Turner 8f43c714a5 A major refresh of the TrueType driver :
- some #ifdefs were included in order to _not_
  compile support for the bytecode interpreter
  when FT_CONFIG_OPTION_BYTECODE_INTERPRETER
  is not defined in "ttconfig.h"

- the glyph loader has been seriously re-designed. It is now
  smaller, simpler and should load composites a bit faster

- works with the TrueType debugger
