Werner Lemberg b48a6094 2000-07-09T19:15:30 Formatting. Moving some internal structures and constants from freetype.h to ftobjs.h. Finally removing FT_LOAD_ANTI_ALIAS. Cleaning up all error codes. Only the used ones have survived :-) Removed unused FT_MAX_GLYPH_FORMATS constant. T2 error codes are now in the range 0x500-0x5FF (instead of `TrueDoc'). Some minor improvements of error return values. Finally fixing error code values in ftraster and ftgrays to be compliant with all other FT error codes.
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++.
Werner Lemberg 5811c7c3 2000-07-02T13:53:16 Formatting. Fixed some errors which prevented compiling.
Werner Lemberg a929ba9b 2000-06-25T06:47:11 applying formatting again
David Turner 994d7747 2000-06-25T04:49:19 various hacks to the TrueType driver that I cannot explain now, but they'll be very useful in the near future :-)
David Turner c3128615 2000-06-23T05:02:13 bugfixes in the Type1 drivers
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.
Werner Lemberg 9ca2af38 2000-06-21T03:03:28 A new formatting orgy. Added some `#if 0' to completely disable the CID AFM stuff. In case this is not correct please fix.
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 e1d5dd78 2000-06-07T04:48:12 Moved all *errors.h header files to include/freetype/internal for consistency. Removed unused error message.
David Turner 2e421319 2000-05-26T22:13:17 moved a lot of things from the TrueType driver to the SFNT module (whose interface has changed, by the way) This allows even more code re-use between TrueType and OpenType formats..
David Turner 51179f0a 2000-05-18T16:18:05 some fixes for 64-bit systems. Mainly changed some FT_TRACE calls to use %p instead of %lx when dumping a pointer address
David Turner 109fcf60 2000-05-17T23:35:37 fixed the sbit loader (src/base/sfnt/ttsbit.c) introduced a new load flag (FT_LOAD_CROP_BITMAP) used to indicate that we want embedded bitmaps to be cropped.. Thanks a lot to Yamano-uchi, Hidetoshi
David Turner c60c61c6 2000-05-12T15:26:58 fixed a potential memory leak when loading embedded bitmaps
David Turner c30aea98 2000-05-12T15:01:18 another massive changes in order to completely avoid compiler warnings with GCC + "-ansi -pedantic -Wall -W" and LCC. Also fixed the compilation of "type1z" with Win32-LCC (its pre-processor is broken !!) Updated the BUILD document too
David Turner 4f2c5544 2000-05-12T10:19:41 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 efce08d6 2000-05-11T18:23:52 major re-organisation of the FreeType 2 directory hierarchy
David Turner 7f615aef 2000-03-13T11:49:20 renamed all outlines functions to the FT_Outline_<action> syntax..
David Turner 08fdac98 2000-02-21T16:01:33 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
David Turner 85168805 2000-02-13T13:38:27 small bug fix used to compile when the SFNT module doesn't support embedded bitmaps and postscript names..
David Turner 1a26888d 2000-02-10T16:17:23 some changes to ensure that the code compiles cleanly when TT_CONFIG_OPTION_POSTSCRIPT_NAMES is undefined..
David Turner 8f43c714 2000-02-02T12:16:19 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
David Turner d42c68e8 2000-01-27T13:56:02 many new small, but important, changes there: - modified the interface of the "sfnt" module. There is now a function called "load_format_tag", and another called "load_directory". The first one is in charge of returning the 4-byte tag located at the beginning of a given font file. It understand TrueType collections and parses them automatically The second loads the table directory that is located just after the format tag. This is useful, because the "SFNT" storage scheme can be used by several distinct formats, each with its own format tag. The TrueType driver now checks the format tag in "src/truetype/ttobjs.c" - made some changes to "src/shared/t1types.h" to clearly separate the Type 1 font content from the rest of the T1_Face structure. This will be useful when adding the CFF/Type2 driver that will be able to reuse the "T1_Font" structure within a "TT_Font" one (which really describes a SFNT-based font file). Some changes in "src/type1" were thus performed to reflect this. Note that the current type1 driver will be discontinued in a distant future. More on this later..
David Turner 454a4285 2000-01-13T18:19:51 fixed a bug which caused some font family and style names to be incorrectly ignored..
David Turner fc1f9894 2000-01-07T18:44:50 Finally, the TrueType driver was completely audited. The code should now be 100% compatible with the implementation in FreeType 1.x. It's now time to make a new tag for the repository :-) - David
