Werner Lemberg e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
Werner Lemberg 1a2908bb 2000-09-21T14:10:23 Added support for (3,0) pid/eid.
Werner Lemberg 4a5c142a 2000-08-29T18:37:25 Minor fixes.
David Turner 5878a6d2 2000-08-29T16:03:01 a fix to the computation of the font "text height" (i.e. the baseline-to-baseline distance). Unfortunately, we cannot rely on the OS/2 fields, like sTypoAscender or usWinAscent to compute it. Rather, we only look at the horizontal header's content. In case the "line gap" is set to 0, we compute the text height as 115% of the ascender+descender value.. (this percentage is based on the values found in many Windows fonts).
Werner Lemberg 9a814fab 2000-08-06T19:48:47 Yamano-uchi added support for SFNT-wrapped CID bitmap font files (with minor modifications from WL).
Werner Lemberg d060a75b 2000-07-20T06:57:41 Formatting. Rudimentary support for autoconf (still using GNU make) Say `make unix'.
David Turner 6930b45f 2000-07-19T17:13:03 - introduced FT_Get_Glyph_Name (see freetype.h) to access individual glyph names. Changed some drivers to support it through a new interface named "glyph_name". - introduced FT_Get_Sfnt_Name (see ftnames.h) to access the SFNT name table in a TrueType/OpenType file..
Werner Lemberg e1bbc017 2000-07-19T06:25:56 Formatting. Fixing documentation.
Werner Lemberg 7fa51b55 2000-07-08T19:51:42 Formatting. Adding some trivial error checking. Adding/Fixing tracing levels.
David Turner a90663f5 2000-07-08T00:41:13 vast clean-up of the sources in order to allow flat directory compilation (by defining the FT_FLAT_COMPILE macro at compile time..) moved "freetype2/BUILD" to "freetype2/docs/BUILD"
Werner Lemberg bd5ae400 2000-07-05T04:32:02 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 c6a92202 2000-07-04T18:12:13 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..
Werner Lemberg a8bbc267 2000-07-01T14:06:46 Formatting as usual... Adding trivial argument checking to some functions. Added dynamic driver interface to cidriver. Minor `version' fixes for macfont and psnames modules. Removed unnecessary files
Werner Lemberg cc9fc49c 2000-06-30T06:21:26 Formatting... Applying some fixes from Tom.
David Turner 32b85e67 2000-06-29T21:48:58 various bug fixes in the postscript font drivers (mainly they added one un-necessary point to each contour..)
Werner Lemberg deb4e983 2000-06-29T03:14:25 Formatting... Preprocessor lines now always start the line. Improved error handling in `base' module. Fixed a out-of-bounds error in ttgload.
David Turner 9d636b6d 2000-06-27T23:32:27 various cleanups to reduce compiler warnings + support for CID-keyed fonts in the CFF driver (still some unexpected bugs though..)
David Turner 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.
David Turner f9b8dec4 2000-06-16T19:34:52 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 7a4fda88 2000-06-13T23:21:00 The next round of formatting, checking documentation, etc.
Werner Lemberg 78575dc0 2000-06-12T19:36:41 A lot of formatting. Added more tracing levels. More Makefile fixes. Minor other changes.
Werner Lemberg 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).
Werner Lemberg 920d41e0 2000-06-05T14:32:32 Removing trailing whitespace.
Werner Lemberg 4e6dd858 2000-06-05T05:26:15 freetype.h: Adding ft_encoding_xxx values for some CJK encodings. Fixing copyright notice on many files. Changed some tracing levels. A lot of formatting, fixing documentation etc. as usual.
David Turner b1677a87 2000-05-29T20:37:41 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)..
David Turner 241e151e 2000-05-28T17:15:37 oops, forgot to commit these files
