- 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.

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 :-)

ftview now has two new options: -d activates debugging, and -l sets the
trace level.
Since FT2 is still beta, I've activated the FT_DEBUG_xxx macros by default.
To make reasonable output, I've changed some TRACEx macros to other levels.

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)..

removed TT_MAX_SUBGLYPHS macro, there is no static
limit on the number of subglyphs in a TrueType font..
changed the default number of gray levels used by the
smooth renderer to 256 (instead of 128). Of course, the
human eye can't tell a difference ;-)

"ftrast.c" now works for monochrome bitmaps, and doesn't

(backwards compatibility) in order to completely replace
"ftraster.c"

Consider the smooth renderer completed ! It will probably
be moved to "freetype2/src/base" soon and become part
of the library.
changes include:
- fixed a bug which prevented large spans being drawn correctly.
- now renders large glyphs that overflow the render pool.
- various performance enhancements. the renderer now
renders large glyphs with much greater speed :-)
- also faster with small glyphs ..
future plans:
- fix a vertical-dropout bug in the standard raster (b&w)
- write a demonstration program to demonstrate direct
composition..
|
|

2000-03-28T11:22:31
|
|
major changes to the library:
- there is now a "convenience" API to manage glyphs in
"include/ftglyph.h". See the demo program "ftstring" for
an example..
- the raster interface has been changed in order to allow
direct composition through user-provided callbacks. This
has been tested but isn't demonstrated for now in "demos"
- the FT_LOAD_NO_RECURSE flag is supported, as this is
required by some new code in the auto-hinting engine
- some bug fixed in FT_MulFix which made FT_xxx_Transform
return incorrect results..

Could be easily modified to reach the level of strtto when
we have the relevant OpenType module handy..

updated the "smooth" anti-aliaser. By increasing the number
of segments used to decompose a bezier curve, we get rid
of the "fuzz-fuzz" factor.
it's also faster than the standard renderer after tweaking.
Note that it isn't completed yet..

Added a new version of the "smooth". This one uses
an algorithm that is very close to our standard raster.
However, it is (theorically for now) capable of direct
composition !!
