f0df85ba	2000-06-22T00:17:42	- 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.
e35cac66	2000-06-11T03:46:57	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).
1c0d4acb	2000-06-06T20:41:48	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

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

EXPORT_DEF renamed to FT_EXPORT_DEF + reformating/spacing

bfe2f98f

2000-05-12T12:17:15

a new massive grunt work. Redefined the EXPORT_DEF, EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to let them take an argument.. This is needed to compile the library as a DLL on some platforms that have different compiler conventions..
