Wu, Chia-I (吳佳一) f5aa47be 2006-02-14T06:40:10 Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading and parsing code is moved here. Move `tt_face_get_metrics' here from the truetype module. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

Werner Lemberg a3f4da8e 2003-04-29T13:23:47 Minor cleanups.
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 b280537b 2003-03-13T21:07:51 * src/base/ftdbgmem.c, docs/DEBUG.TXT: added new environment variables to control memory debugging with FreeType. See the description of "FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX" in DEBUG.TXT * src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c, ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a small memory leak * src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that only happened when trying to resize an array would end in an OOM. * src/smooth/ftgrays.c: removed compiler warnings / volatile bug * src/truetype/ttobjs.c: removed segmentation fault that happened in tight memory environments.
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 14018b4a 2003-01-12T18:26:10 2003-01-11 David Chester <davidchester@qmx.net> * include/freetype/config/ftoption.h, src/autohint/ahglobal.h, src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahtypes.h: included David Chester's patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX macros to control individual "features". Note that all improvements are enabled by default, but can be tweaked for optimization and testing purpose. The configuration macros will most likely disappear in the short future. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h: fixed a structure field definition to avoid memory overwrites
David Turner 25f845aa 2002-09-09T23:45:29 * src/cache/ftccache.i: fixed a bug that prevented compilation in debug mode of template instantiation * src/cff/cffparse.c: fixed the CFF table loader. It didn't accept empty arrays, and this prevented the loading of certain fonts. * src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to prevent seg fault when hints are provided in an empty glyph !! * include/freetype/ftimage.h: removed incorrect "zft_" definitions and updated constants documentation comments * include/freetype/freetype.h (FT_FaceRec): updating documentation comment. The "descender" value is always *negative*, not positive !
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_.
Graham Asher ce12182c 2002-08-01T15:29:17 Modified incremental loading interface to be closer to David Turner's preferences. The header freetype.h is not now affected, the interface is specified via an FT_Parameter, the pointer to the interface is hidden in an internal part of the face record, and all the definitions are in ftincrem.h.
Werner Lemberg b3d5e9cf 2002-07-28T05:05:24 s/ft_memset/FT_MEM_SET/. s/FT_MEM_SET/FT_MEM_ZERO/ where appropriate.
Werner Lemberg 7f74a52a 2002-07-26T09:09:10 Fixing ChangeLog entries. Some formatting. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: s/memset/ft_memset/. * src/autohint/ahhint.c (ah_hint_edges_3): Fix compiler warning. * src/cff/cffload.c (cff_encoding_load): Remove `memory' variable. * src/cff/cffcmap.c (cff_cmap_encoding_init): Remove `psnames' variable. * src/truetype/ttgload.c (load_truetype_glyph): Remove statement without effect. * src/truetype/ttdriver (Get_Char_Index, Get_Next_Char): Removed.
Graham Asher 11f0ab7d 2002-07-24T13:58:21 FIX for bug reported by Sven Neumann [sven@gimp.org] on the FreeType development forum: "If FT_CONFIG_OPTION_INCREMENTAL is undefined (this is the default), the TrueType loader crashes in line 852 of src/truetype/ttgload.c when it tries to access face->glyph_locations.".
Graham Asher 13217f25 2002-07-18T15:59:23 Added the incremental loading system for the TrueType driver. Tested using my own unit test code.

David Turner e459d742 2002-03-22T13:52:37 * include/freetype/internal/ftmemory.h, and a lot of other files !!: changed the names of memory macros. Examples: MEM_Set => FT_MEM_SET MEM_Copy => FT_MEM_COPY MEM_Move => FT_MEM_MOVE ALLOC => FT_ALLOC FREE => FT_FREE REALLOC = >FT_REALLOC FT_NEW was introduced to allocate a new object from a _typed_ pointer.. note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer arguments. This results in _lots_ of sources being changed, but makes the code more generic and less error-prone..
David Turner 7d3a2642 2002-03-20T10:49:31 * renaming stream macros. Examples: FILE_Skip => FT_STREAM_SKIP FILE_Read => FT_STREAM_READ ACCESS_Frame => FT_FRAME_ENTER FORGET_Frame => FT_FRAME_EXIT etc...

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 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 `##'.

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
David Turner b1aabf4c 2000-11-30T23:48:22 - added support for the free command-line Borland C++ compiler in the "builds" directory - modified a few files because BCC32 didn't like certain comparisons (UInt compared with a UShort, apparently the UShort is promoted to an Int) - updated the INSTALL file to include IDE compilation, prevent against BSD Make, and clarify the use of "make setup" (instead of "make") for build configuration
Werner Lemberg d157fcf0 2000-11-29T04:45:26 * src/truetype/ttobjs.c (TT_Init_Size): Fix #ifdef's to work with disabled interpreter also. * src/base/ftnames.c (FT_Get_Sfnt_Name_Count): Fix incorrect parentheses.
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 50dd5858 2000-09-22T03:37:45 Applied a patch from Hidetoshi for embedded bitmap metrics support.
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 e72c9fec 2000-07-31T18:59:02 Simplifying the FIELD_* and FRAME_* macros. Before calling these macros, you should #define FT_STRUCTURE to the structure which will be filled. Replaced FT_FIELD_REF with FT_FIELD_SIZE, FT_FIELD_SIZE_DELTA, and FT_FIELD_OFFSET to make the code more readable; additionally, it should be more portable because we no longer cast a pointer to an FT_UShort (which e.g. fails with Sun's C++ compiler) but computes the difference between two pointers which is guaranteed to work. Fixing warnings (and C++ errors) while using Sun's latest cc and CC incarnations. Most of them are related to variable shadowing.

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 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.

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.
