Werner Lemberg ffa033b1 2005-08-19T08:56:29 * src/truetype/ttgload.c (load_truetype_glyph): Fix compiler warnings. Formatting.
Wu, Chia-I (吳佳一) 0142e6af 2005-08-16T01:54:59 * src/truetype/ttinterp.c, src/truetype/ttinterp.h: Remove original TT_Done_Context and rename TT_Destroy_Context to TT_Done_Context with slight changes. * src/truetype/ttobjs.h (tt_slot_init): New function. * src/truetype/ttobjs.c (tt_driver_init): Initialize execution context here. (tt_slot_init): New function to create extra points for the internal glyph loader. We then use it directly, instead of face's glyph loader, when loading glyph. * src/truetype/ttdriver.c: Use tt_slot_init for glyph slot initialization. (TT_Load_Glyph): Load flag dependencies are handled here. Return error if size is NULL. * src/truetype/ttgload.c: Heavy cleanup and refactor. (TT_Hint_Glyph): New funcion to hint a zone, prepared by caller. (TT_Process_Simple_Glyph): Use loader->pp's instead of recalculating. Use TT_Hint_Glyph. No need to save/restore loader->stream before/after TT_Vary_Get_Glyph_Deltas now. (TT_LOADER_SET_PP): New macro to calculate and set the four phantom points. (TT_Process_Composite_Component, TT_Process_Composite_Glyph, load_truetype_glyph): Refactor load_truetype_glyph into these three functions. Never set exec->glyphSize to 0. (close #13107) Forget glyph frame before calling TT_Process_Simple_Glyph. (TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into these three functions. Set various fields of `glyph' here, instead of in load_truetype_glyph and compute_glyph_metrics.
Werner Lemberg 8e3fc5ea 2005-08-03T21:17:53 * src/otvalid/otvcommn.h: Remove dead code. Formatting.

Werner Lemberg 86ae11cf 2004-05-04T16:53:45 * src/truetype/ttobjs.h, src/truetype/ttobjs.c (tt_face_init, tt_face_done, tt_size_init, tt_size_done, tt_driver_init, tt_driver_done): Don't use TT_XXX but FT_XXX arguments which are typecast to the proper TT_XXX within the function. Update code accordingly. * src/truetype/ttdriver.c (Get_Kerning, Set_Char_Sizes, Set_Pixel_Sizes, Load_Glyph, tt_get_interface): Don't use TT_XXX but FT_XXX arguments which are typecast to the proper TT_XXX within the function. Update code accordingly. (tt_driver_class): Remove casts.
Werner Lemberg 8bb07e63 2004-03-27T08:43:17 Add vertical phantom points. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add `top_bearing', `vadvance', `pp3, and `pp4'. * src/autofit/afloader.c (af_loader_load_g): Handle two more points. * src/autohint/ahhint.c (ah_hinter_load): Handle two more points. * src/truetype/ttgload.c (Get_VMetrics): New function. (TT_Load_Simple_Glyph, TT_Process_Simple_Glyph): Handle two more points. (load_truetype_glyph): Use Get_VMetrics. Handle two more points. (compute_glyph_metrics): Thanks to vertical phantom points we now can always compute `advance_height' and `top_bearing'. * src/truetype/ttobjs.h (TT_SubglyphRec): Add vertical phantom points. * src/autohint/ahglyph.c (ah_outline_load): Fix allocation of `news'. Converting some files to Unix end-of-line convention.
David Turner 8b6db86b 2003-08-17T22:09:14 * include/freetype/config/ftoption.h, devel/ftoption.h, include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h, src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead, the same effect can be used by setting a debug-hook with FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
Graham Asher 3ea859f6 2003-04-25T11:40:46 Added the unpatented hinting system, which is compiled only if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in ftoption.h
Werner Lemberg b442ca17 2003-04-23T15:50:27 Cleanups.
David Turner ba4511b8 2003-02-18T22:25:22 * src/truetype/ttdriver.c, src/truetype/ttobjs.h, src/truetype/ttobjs.c, src/truetype/ttinterp.c, src/base/ftobjs.c: fixing the slight distortion problem that occured due to the latest auto-hinter changes
David Turner b08fe2dc 2002-08-27T20:20:29 * massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
Werner Lemberg 91db04cb 2002-04-01T14:25:28 * src/truetype/ttgload.c: 16bit fixes. (TT_Load_Simple_Glyph): Improve debug messages. (load_truetype_glyph): Remove dead code. * src/truetype/ttinterp.c: 16bit fixes. * src/truetype/ttobjs.c: Ditto. * include/freetype/ftsnames.h, include/freetype/internal/sfnt.h, src/cff/cffload.h, src/psaux/psobjs.h, src/truetype/ttinterp.[ch], src/sfnt/ttpost.h: s/index/idx/. formatting, copyright updates.
Werner Lemberg 48c984b5 2002-03-30T16:41:09 * src/cff/cffdrivr.c (cff_get_glyph_name): Fix debug message. * src/cff/cffobjs.c (CFF_Driver_Init, CFF_Driver_Done) [TT_CONFIG_OPTION_EXTEND_ENGINE]: Removed. * src/cff/sfobjs.c (SFNT_Load_Face) [TT_CONFIG_OPTION_EXTEND_ENGINE]: Ditto. * src/truetype/ttobjs.c (TT_Init_Driver, TT_Done_Driver) [TT_CONFIG_OPTION_EXTEND_ENGINE]: Ditto. * src/truetype/ttdriver.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: Renaming driver functions to the FT_<Subject>_<Action> scheme: TT_Init_Driver => TT_Driver_Init TT_Done_Driver => TT_Driver_Done TT_Init_Face => TT_Face_Init TT_Done_Face => TT_Face_Done TT_Init_Size => TT_Size_Init TT_Done_Size => TT_Size_Done TT_Reset_Size => TT_Size_Reset
David Turner b5713c54 2002-03-14T11:26:29 * include/freetype/internal/psglobals.h (removed), include/freetype/internal/pshints.h, src/pshinter/pshglob.h: removing obsolete file * include/freetype/internal/tttypes.h, include/freetype/internal/sfnt.h, src/base/ftnames.c, src/cff/cffdrivr.c, src/sfnt/*.c, src/truetype/*.c: updated SFNT/TrueType type definitions
David Turner bc82f1bb 2002-03-01T02:26:22 * include/freetype/ftconfig.h: changed FT_LOCAL xxxx to FT_LOCAL( xxxx ) everywhere in the source. Sames goes for FT_LOCAL_DEF xxxx translated into FT_LOCAL_DEF( xxxxx )
Werner Lemberg 415235df 2001-06-28T17:49:10 finishing function header formatting updating copyrights
Werner Lemberg 4a2305cf 2001-06-28T07:17:51 formatting
Werner Lemberg 1f7f0e87 2001-06-06T17:30:41 Complete redesign of error codes. Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed. Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets. Its structure is similar to `fterrors.h'. * include/freetype/fterrors.h (FT_NOERRORDEF): New macro. (FT_ERRORDEF): Redefined to use module error offsets. All internal error codes are now public; unused error codes have been removed, some are new. * include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro. All other source files have been updated to use the new error codes; some already existing (internal) error codes local to a module have been renamed to give them the same name as in the base module. All make files have been updated to include the local error files. * src/cid/cidtokens.h: Replaced with... * src/cid/cidtoken.h: This file for 8+3 consistency. * src/raster/ftraster.c: Use macros for header file names.
Werner Lemberg 90d9964e 2000-12-09T00:45:38 * */*.h: Changed body inclusion macro names to start and end with `__' (those which haven't converted yet). Fixed minor conversion issues. * src/winfonts/winfnt.c: Updated to new header inclusion scheme. * */*.[ch]: Changed source files to adhere to the new * src/cff/cff.c, src/cff/rules.mk: Updated. * */*.[ch]: Now using <ft2build.h> as the default build and setup
Werner Lemberg cc069beb 2000-12-08T16:17:16 cleanups
David Turner 19ed8afe 2000-12-08T02:42:29 - 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
Werner Lemberg 4b68007b 2000-11-07T06:30:29 Complementing David's changes with formatting, adding documentation, etc. More `*'-convention formatting, adding the `a' resp. `an' prefix to variables.
David Turner f96594fa 2000-11-06T23:07:51 integrated Yamano-Uchi changes to the base source code. However, I've made a few modifications: - there is no new field named "driver" in "FT_SizeRec" - the new fields in "TT_SizeRec" are: strike_index :: value 0xFFFF means "no sbit strike selected" strike_metrics :: the FT_Size_Metrics structure corresponding to the currently selected strike - the code in "ttload.c" has been somewhat cleaned up too thanks a lot, Y-U !! - David
Werner Lemberg dc72aff4 2000-11-04T08:33:38 Finishing David's latest changes (there were some errors in it).
David Turner 76a5f623 2000-11-04T01:55:49 major reformatting of the sources: FT_EXPORT_DEF => FT_EXPORT FT_EXPORT_FUNC => FT_EXPORT_DEF BASE_DEF => FT_BASE BASE_FUNC => FT_BASE_DEF LOCAL_DEF => FT_LOCAL LOCAL_FUNC => FT_LOCAL_DEF LOCAL_FUNC_X => FT_CALLBACK_DEF LOCAL_DEF_X => FT_CALLBACK_TABLE FT_CPLUSPLUS => FT_CALLBACK_TABLE_DEF
David Turner c5cdf8bc 2000-07-27T21:40:22 re-adding a "unix-dev.mk". Debugging libtool output is just too much of a pain for me, I prefer a good old static lib without optimizations :-) "make devel" is back on Unix then..
Werner Lemberg 321cd27d 2000-07-27T11:20:20 Removing compiler warnings about unused portions of code. Now unix.in uses absolute paths also to overcome problems with libtool. To do that in a consistent way I had to modify the rules how to handle $OBJ_DIR (and consequently $LIB_DIR): You should set $OBJ_DIR explicitly on the command line (or environment).
Werner Lemberg 5811c7c3 2000-07-02T13:53:16 Formatting. Fixed some errors which prevented compiling.
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.
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 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 e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
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 7f7aadf4 2000-03-13T12:57:27 finished moving all configuration macros to "config/ftoption.h"
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 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 d2b1f357 1999-12-16T23:11:37 Initial revision
