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).
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 !!)
David Turner e161ee44 2000-07-10T22:03:10 fixed a bug that caused invalid clipping of monochrome bitmaps when they were blitted on the left edge of an 8-bit pixmap..
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 43a2f656 2000-07-05T18:23:38 fixed a few bugs, cleaned up some code
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 5811c7c3 2000-07-02T13:53:16 Formatting. Fixed some errors which prevented compiling.
David Turner f9ca2bb5 2000-06-30T23:12:55 managed to re-design entirely the API in <freetype/ftglyph.h> It is now really the "glyph factory" that Stefan was probably dreaming about.. fixed some recent formatting errors from Werner ;-) cleaned up the demonstration programs from most of the rust that they had, though I'm sure someone is going to re-format them really soon !! "ftstring" now uses the new ftglyph.h API, and is now faster and smaller.. yep..
David Turner 5ae831c1 2000-06-30T01:31:22 changes used to implement the auto-hinting support
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 81bb4ad9 2000-06-28T04:19:49 latest clean-ups.. The code compiles with NO WARNINGS with GCC and Visual C++ (also with LCC minus debugging options)
David Turner 74abee8e 2000-06-27T23:31:53 various cleanups to reduce compiler warnings
Werner Lemberg dcd2e14c 2000-06-25T07:43:15 forgotten fixes.
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 2a98b3c4 2000-06-23T13:47:55 reduced some nasty memory leaks
David Turner 90f68b72 2000-06-23T12:26:14 still more updates to the TrueType driver to make it more "extensible"..
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 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.
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 e1d5dd78 2000-06-07T04:48:12 Moved all *errors.h header files to include/freetype/internal for consistency. Removed unused error message.
Werner Lemberg 1c0d4acb 2000-06-06T20:41:48 Fine-tuned a lot of tracing levels to make them more functional with ftview. Added a lot of \n to tracing messages. Fixed a serious bug in loading SBit offsets (missing parentheses around a xxx ? yyy : zzz construct). Replaced most GET_xxx() functions with calls to READ_Frame() in ttsbit.c
David Turner 04aa800c 2000-06-01T03:27:48 added a CID-keyed font driver in "src/cid" fixed two bugs in the smooth renderer
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 2c5f482b 2000-05-26T22:10:08 removed obsolete files
David Turner 1fb6eea7 2000-05-24T00:31:14 EXPORT_DEF renamed to FT_EXPORT_DEF + reformating/spacing
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 3475e7fb 2000-05-17T20:56:01 removed TT_MAX_SUBGLYPHS macro, there is no static limit on the number of subglyphs in a TrueType font.. changed the default number of gray levels used by the smooth renderer to 256 (instead of 128). Of course, the human eye can't tell a difference ;-)
David Turner e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
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 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 b7ef2b09 2000-05-02T11:01:12 in order to ensure that the bytecode interpretation is exactly equivalent to the one in FT 1.4, moved some code from the old version of FreeType in order to compute vector normalization a bit differently
David Turner 48641d60 2000-05-02T11:00:06 added a simple line to set "glyph.control_len" when loading a simple glyph. This is used to compute statistics on font files..
David Turner f8a116fb 2000-04-25T16:11:12 implemented extra interface for "FT_Get_Sfnt_Table"
David Turner ed7f62ac 2000-03-28T11:19:28 support for FT_LOAD_NO_RECURSE needed by the auto-hinter
David Turner 7f7aadf4 2000-03-13T12:57:27 finished moving all configuration macros to "config/ftoption.h"
David Turner 3246efed 2000-03-13T12:12:46 first step towards moving all configuration options to the single "config/ftoption.h"
David Turner 7f615aef 2000-03-13T11:49:20 renamed all outlines functions to the FT_Outline_<action> syntax..
David Turner 41dbcbf6 2000-03-09T11:46:25 reformatting, changing the FT_Outline structure: - "flags" have been renamed to "tags" - "outline_flags" have been renamed to "flags" Look for more re-formatting today..
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..
Werner Lemberg febe3fbe 2000-03-05T01:14:19 A first check of FT2's Make system. Many smaller and larger bugs have been fixed: . Removing unused variables. . detect.mk files now must provide $(CONFIG_FILE) and not $(CONFIG_RULE). . ansi.mk will now be really used as a fallback if the detect mechanism fails. . ANSIFLAGS will now be really used (fixing a typo). . `make clean' now works (again two typos). . Detection of gcc on Unix has been fixed (using the `-v' option instead of `--version'). . `make devel' now works (on Unix). . Fixing *again* a bug in demos/graph/x11/rules.mk to allow multiple use of `-L' compiler options. . $(BASE_H) now contains a few more header files. As usual, a lot of formatting (not finished yet).
Just van Rossum 8c5c932e 2000-03-02T10:53:32 fixed typo in comment
David Turner 7bb7fede 2000-02-28T11:23:36 fixed a bug which appeared when loading unscaled composite glyphs
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 861ba624 2000-02-15T12:54:51 small fix (reduce compiler warnings)
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 1ab77fdf 2000-02-10T18:08:17 some updates to make everything compile clean
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 71ec10ef 2000-02-10T16:09:35 support for the IGNORE_GLOBAL_ADVANCE_WIDTH loading flag
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..
David Turner 3ba47068 2000-01-17T11:25:57 some updates to the "rules.mk" files. Basically, we now use "$(FT_COMPILE)" instead of "$(FT_CC)" in order to compile the library. $(FT_COMPILE) uses the $(ANSI_FLAGS) variable used to define ANSI-compliance flags for the current compiler. It is used to compile the library exclusively (some demo programs will _not_ compile properly with these flags set).
David Turner 3b925ef7 2000-01-17T11:22:59 fixed a minor bug in the computation of the vertical metrics top-side bearing
David Turner 454a4285 2000-01-13T18:19:51 fixed a bug which caused some font family and style names to be incorrectly ignored..
Werner Lemberg f697866e 2000-01-08T20:00:54 Bugfix: prep table is optional.
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
David Turner 10effdf6 1999-12-29T00:22:24 Added the rules files `module.mk' to "sfnt", "truetype" and "type1" to reflect the new modules/drivers list management performed through the file `freetype2/config/modules.mk' Changed the driver header files to reflect the new modules/drivers list management. We get rid, at last, of the infamous pre-processor tricks used to build the list at compile time. `src/base/ftinit.c' is also modified to reflect the changes..
David Turner d2b1f357 1999-12-16T23:11:37 Initial revision
