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.
David Turner 6ce03efb 2001-03-20T14:50:04 * include/freetype/config/ftheader.h, include/freetype/ftsnames.h: renamed "ftnames.h" to "ftsnames.h", and FT_NAMES_H to FT_SFNT_NAMES_H * docs/docmaker.py: added generation of INDEX link in table of contents
David Turner 8d3a401f 2001-03-20T11:14:24 * 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..
David Turner 170c0d4c 2000-12-13T19:55:11 * include/freetype/config/ft2build.h, include/freetype/internal/internal.h: fixed header inclusion macros to use direct definitions. This is the only way to do these things in a portable way :-( The rest of the code should follow shortly though everything compiles now.. * builds/compiler/intelc.mk, builds/compiler/watcom.mk, builds/win32/detect.mk: added support for the Intel C/C++ compiler, as well as _preliminary_ (read: doesn't work !!) support for Watcom. Also added a new setup target. Type "make setup list" for a list of supported command-line compilers on Win32..
Werner Lemberg d5c1b27d 2000-12-12T22:28:12 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT): Removed. ANSI C doesn't (explicitly) allow macro expansion in arguments using `##'. (FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory names directly. Make them configurable. Use `##' to strip leading and trailing spaces from arguments. * builds/unix/ft2unix.h: Adapted. * src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream, ft_close_stream): Use FT_CALLBACK_DEF. * builds/unix/ftsystem.c: Use new header scheme. (FT_Done_Memory): Use free() from FT_Memory structure. * src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes. * include/freetype/config/ft2build.h (FT2_CONFIG_ROOT, FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE, FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.
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 f1ca2344 2000-11-29T15:18:54 * src/sfnt/sfdriver.c: Include ttsbit.h and ttpost.h only conditionally. * src/truetype/ttdriver.c (Set_Char_Sizes, Set_Pixel_Sizes): Set `size->strike_index' only conditionally. * src/type1/t1driver.c, src/type1/t1objs.c: Include t1afm.h only conditionally. * src/winfonts/winfnt.h: Move all type definitions to... * src/include/freetype/internal/fnttypes.h: New file. * src/winfonts/winfnt.c: Use it. * include/freetype/internal/ftdebug.h: Replaced FT_CAT and FT_XCAT with a direct solution (which also satifies picky compilers).
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
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
Werner Lemberg ab855232 2000-10-31T22:13:54 Fixing include header for a `make multi' build. Finishing formatting of cache stuff. Fixed getDriverClass stuff -- added it to winfnt.c also. Note that this still has to be documented.
Werner Lemberg e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
Werner Lemberg 29a90e26 2000-08-03T00:03:08 Updating unix/ftconfig.in to recent config/ftconfig.h changes. More C++ fixes: Introducing LOCAL_FUNC_X for local functions used in function pointers (there are no local anonymous functions in C++) and FT_CPLUSPLUS (instead of FT_EXPORT_VAR) to define linkage of structures which contain function pointers.
Werner Lemberg 3a89c2a4 2000-08-01T17:05:20 Removing FT_MAKE_OPTION_SINGLE_LIBRARY_OBJECT. It has never worked. Instead, define BASE_DEF() and BASE_FUNC() similarly to FT_EXPORT_DEF() and FT_EXPORT_FUNC(), respectively, allowing the programmer to define proper types and/or export lists for multiple DLLs if necessary (e.g. ftbase.dll -- standalone, fttype1.dll -- needs ftbase.dll, etc.). The library is finally compiling and linking natively with a C++ compiler!
David Turner 5fe4c00e 2000-07-26T19:04:08 - fixed the incorrect SO extension for Visual C++ - disabled the TrueType interpreter by default - disabled the "type1" driver, "type1z" is now used by default (the internal driver name is "type1" now !!)
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"
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..
David Turner 5ae831c1 2000-06-30T01:31:22 changes used to implement the auto-hinting support
Werner Lemberg a929ba9b 2000-06-25T06:47:11 applying formatting again
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 e3c11d7f 2000-06-16T06:49:56 A new round of formatting, adding/fixing documentation etc.
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.
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 e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
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 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..
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 d186a361 2000-05-02T17:41:41 various updates to reduce the compilation warnings
David Turner f8a116fb 2000-04-25T16:11:12 implemented extra interface for "FT_Get_Sfnt_Table"
David Turner 0f99ddda 2000-03-06T13:23:32 changed the structure of FT_Outline in order to pack all outline flags in a single integer.. Changed the rest of the library and demo programs accordingly..
Just van Rossum 8c5c932e 2000-03-02T10:53:32 fixed typo in comment
David Turner dba4b324 2000-02-10T16:08:59 small update to the kerning code
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..
