- updated all source files to adhere to the new inclusion scheme - the CFF loader now loads the encodings and charset tables though doesn't use them for now
2000-12-08 03:42:29 +01:00
#include <ft2build.h>
* 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..

added a new experimental Type 1 driver. This version sports several improvements compared to "src/type1". Briefly : - the postscript-like interpreter is now gone. We now perform pattern-matching to load our font content. The resultant code is much faster, smaller, and easier to maintain. For a more detailed description, see the comments at the start of "src/type1z/t1objs.c" - the glyph loader will be greatly simplified really soon, and the clumsy hinter will be ditched in favor of a more general auto-hinting module (when we get one). The goal is to strip down the Type1 driver to about 15-20 Kb. This is still an experimental version. It is added to the repository for archiving. You should not try to use it for now (it won't work because some crucial parts are _knowingly_ ignored for now !). Note that the "old" type1 driver will probably move to the "demos/src" directory, in order to show how one can replace one given font driver at runtime (and to provide the functionality of the "t1dump" program).

added a new experimental Type 1 driver. This version sports several improvements compared to "src/type1". Briefly : - the postscript-like interpreter is now gone. We now perform pattern-matching to load our font content. The resultant code is much faster, smaller, and easier to maintain. For a more detailed description, see the comments at the start of "src/type1z/t1objs.c" - the glyph loader will be greatly simplified really soon, and the clumsy hinter will be ditched in favor of a more general auto-hinting module (when we get one). The goal is to strip down the Type1 driver to about 15-20 Kb. This is still an experimental version. It is added to the repository for archiving. You should not try to use it for now (it won't work because some crucial parts are _knowingly_ ignored for now !). Note that the "old" type1 driver will probably move to the "demos/src" directory, in order to show how one can replace one given font driver at runtime (and to provide the functionality of the "t1dump" program).

FT_Int n;
- 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.

added a new experimental Type 1 driver. This version sports several improvements compared to "src/type1". Briefly : - the postscript-like interpreter is now gone.

For a more detailed description, see the comments at the start of "src/type1z/t1objs.c" - the glyph loader will be greatly simplified really soon, and the clumsy hinter will be ditched in favor of a more general auto-hinting module (when we get one). The goal is to strip down the Type1 driver to about 15-20 Kb. This is still an experimental version. It is added to the repository for archiving. You should not try to use it for now (it won't work because some crucial parts are _knowingly_ ignored for now !). Note that the "old" type1 driver will probably move to the "demos/src" directory, in order to show how one can replace one given font driver at runtime (and to provide the functionality of the "t1dump" program).

added a new experimental Type 1 driver. This version sports several improvements compared to "src/type1". Briefly : - the postscript-like interpreter is now gone. We now perform pattern-matching to load our font content. The resultant code is much faster, smaller, and easier to maintain. For a more detailed description, see the comments at the start of "src/type1z/t1objs.c" - the glyph loader will be greatly simplified really soon, and the clumsy hinter will be ditched in favor of a more general auto-hinting module (when we get one). The goal is to strip down the Type1 driver to about 15-20 Kb. This is still an experimental version. It is added to the repository for archiving. You should not try to use it for now (it won't work because some crucial parts are _knowingly_ ignored for now !). Note that the "old" type1 driver will probably move to the "demos/src" directory, in order to show how one can replace one given font driver at runtime (and to provide the functionality of the "t1dump" program).

* src/autohint/ahtypes.h (AH_Hinter): Add elements `disable_horz_edges', `disable_vert_edges'. * src/autohint/ahhint.c (ah_hint_edges_3, ah_hinter_hint_edges): Use them (and remove static variables with the same names). * src/pcf/pcfutil.c (BitOrderInvert): Add `const'. * docs/glnames.py: Updated to latest pstables.h changes. * src/psnames/pstables.h: Add more `const'. * src/pcf/pcfutil.c: Ditto. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixing typo (FT_Glyph_Done -> FT_Done_Glyph). * include/freetype/ttnameid.h: Added some new Microsoft language codes and LCIDs as found in Office Xp. * builds/hurd/detect.mk: New file. Added support to detect the GNU Hurd operating system as Unix-like. Fix submitted by Anthony Fok <foka@debian.org>. * src/type1/t1gload.c (T1_Load_Glyph): Set glyph control data to the the Type 1 glyph charstring (used by conversion programs). Submitted by Ha Shao <hashao@chinese.com>. * src/base/ftgrays.c (grays_sweep): The function didn't exit immediately if `num_cells' was 0 as it should. Thanks to Boris for finding this out. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixed memory leak when bitmap rendering fails (thanks to Graham Asher). * docs/docmaker.py, include/freetype/*.h: Updated the DocMaker script to support chapters and section block ordering. Updated the public header files accordingly. * src/base/ftglyph.c (FT_Glyph_Copy): Advance width and glyph format were not correctly copied.

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)..
