Werner Lemberg 8eacad6d 2005-09-19T07:07:11 * freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a font to have no `head' table if tables `SING' and `META' are present; this is to support `SING Glyphlet'. `SING Glyphlet' is an extension to OpenType developed by Adobe primarily to facilitate adding supplemental glyphs to an OpenType font (with emphasis on, but not necessariy limited to, gaiji to a CJK font). A SING Glyphlet Font is an OpenType font that contains the outline(s), either in a `glyf' or `CFF' table, for a glyph; `cmap', `BASE', and `GSUB' tables are present with the same format and functionaliy as a regular OpenType font; there are no `name', `head', `OS/2', and `post' tables; there are two new tables, `SING' which contains details about the glyphlet, and `META' which contains metadata. Further information on the SING Glyphlet format can be found at: http://www.adobe.com/products/indesign/sing_gaiji.html * freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New macros for the OpenType tables `SING' and `META'. These two tables are used in SING Glyphlet Format fonts.
Werner Lemberg 3774b997 2005-08-20T05:45:42 * src/sfnt/ttload.c (tt_face_load_metrics_header): Ignore missing `hhea' table for SFNT Mac fonts. Change based on a patch by mpsuzuki@hiroshima-u.ac.jp.
Werner Lemberg 22ad9ef0 2005-05-09T22:11:36 Handle unsorted SFNT type 4 cmaps correctly (reported by Dirck Blaskey). * src/sfnt/ttcmap.h (TT_CMap): Add member `unsorted'. * src/sfnt/ttcmac.c: Use SFNT_Err_Ok where appropriate. (tt_cmap0_validate, tt_cmap2_validate, tt_cmap6_validate, tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate): Use `FT_Error' as return type. (tt_cmap4_validate): Use `FT_Error' as return type. Return error code for unsorted cmap. (tt_cmap4_char_index, tt_cmap4_char_next): Use old code for unsorted cmaps.

David Turner e5680279 2005-02-26T00:12:04 * many, many files: several memory optimizations were implemented to drastically reduce the heap usage of FreeType, especially in the case of memory-mapped files. The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e. when it doesn't compromise performance). This had several impacts: first, opening vera.ttf uses a ridiculous amount of memory (when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you'll save at least 20 Kb compared to the non optimized case. performance of various operations, including open/close has also been dramatically improved. More optimisations to come. The auto-hinter eats memory like crazy? This must be stopped...

David Turner ae26c684 2003-02-25T20:37:50 * src/cache/ftccmap.c: the cmap cache now supports UCS-4 charmaps when available in Asian fonts * src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in comments * src/truetype/ttdriver.c (Set_Char_Sizes): fixed a rounding bug when computing the scale factors for a given character size in points with resolution.
David Turner 79c23ae2 2003-01-22T22:53:55 * src/sfnt/ttload.c (sfnt_dir_check): relaxed the "head" table size verification to accept a few broken fonts who pad the size incorrectly (the table should be padded, but its "size" field shouldn't per se the spec)
Graham Asher 550fd439 2003-01-13T10:20:08 TrueType typefaces lacking hmtx (horizontal metrics) tables are tolerated if the incremental interface system is enabaled and an incremental interface has been specified. This is necessary to support some typefaces passed from GhostScript.

Formatting, minor doc fixes.
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 1039234c 2002-08-18T07:15:52 Adding some comments.
Werner Lemberg bdb10748 2002-07-27T22:51:28 * src/sfnt/ttload.c (sfnt_dir_check): Make it work with TTCs.
Werner Lemberg 7f74a52a 2002-07-26T09:09:10 Fixing ChangeLog entries.

Graham Asher 320da730 2002-07-19T11:40:51 More work on supporting fonts passed from GhostScript: sfnt_dir_check now ignores the tables 'glyx' and 'locx' which are hacked-out versions of 'glyf' and 'loca' in some PostScript Type 42 fonts, and will generally be invalid.
David Turner fed59b7c 2002-07-17T22:51:06 * src/sfnt/ttload.c (TT_Load_SFNT_Header): fixed a recent bug that prevented OpenType fonts to be recognized by FreeType
David Turner 3e19d85d 2002-07-17T21:52:20 * include/freetype/config/ftoption.h, include/freetype/internal/tttypes.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/pcf/pcfdrivr.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h, src/sfnt/ttload.c, src/type1/t1objs.c, src/type42/t42objs.c, src/winfonts/winfnt.c: code cleanup, FT_CONFIG_OPTION_USE_CMAPS is now the default
David Turner b55464fa 2002-07-11T23:55:18 small fix
David Turner 3314a975 2002-07-11T23:51:44 small fix
David Turner 7acd73fd 2002-07-11T23:41:14 * src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttdriver.c: changing the SFNT loader to check for SFNT-based font files differently. We now ignore the range "helper" fields and check the "head" table's magic number instead.
David Turner a1e45652 2002-06-11T20:35:58 * builds/win32/ftdebug.c: added a missing #endif * src/sfnt/ttload.c, src/bdf/bdflib.c: removing compiler warnings * src/type42/t42objs.c: removed the bug that prevented un-hinted outlines to be loaded
Werner Lemberg 877ff678 2002-05-28T06:03:10 * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT but FT_STREAM_READ. Declare `stream' variable.
David Turner 791d83a6 2002-05-27T23:52:01 * include/freetype/internal/tttypes.h, src/sfnt/ttload.c, src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c: fixing the SFNT name table loader to support various buggy fonts. it now ignores empty name entries, entries with invalid pointer offsets and certain fonts containing tables with broken "storageOffset" fields. name strings are now loaded on demand, which reduces the memory requirements for a given FT_Face tremendously (for example, the name table of Arial.ttf is about 10Kb and contains 70 names !!) finally, this is a _quick_ fix. The whole name table loader and interface will be rewritten in a much more cleanly way shortly, once CSEH have been introduced in the sources.

Werner Lemberg 94ffae52 2002-04-14T00:54:32 * src/cff/cffgload.c (CFF_Parse_CharStrings): s/rand/Rand/ to avoid compiler warning. formatting/fixing ChangeLog
David Turner d15bc0d1 2002-04-12T09:31:48 * README.UNX: updated the Unix-specific quick-compilation guide to warn about the GNU Make requirement at compile time.. * include/freetype/config/ftstdlib.h, include/freetype/config/ftconfig.h, include/freetype/config/ftheader.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, src/autohint/ahoptim.c, src/base/ftdbgmem.c, src/base/ftdebug.c, src/base/ftmac.c, src/base/ftobjs.c, src/base/ftsystem.c, src/cache/ftcimage.c, src/cache/ftcsbits.c, src/cff/cffdriver.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cid/cidload.c, src/cid/cidparse.c, src/cid/cidriver.c, src/pcf/pcfdriver.c, src/pcf/pcfread.c, src/psaux/t1cmap.c, src/psaux/t1decode.c, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c, src/pshinter/pshrec.c, src/psnames/psmodule.c, src/raster/ftraster.c, src/sfnt/sfdriver.c, src/sfnt/ttload.c, src/sfnt/ttpost.c, src/smooth/ftgrays.c, src/type1/t1afm.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1load.c, src/type1/t1objs.c, src/type1/t1parse.c: added the new configuration file "ftstdlib.h" used to define aliases for all ISO C library functions used by the engine (e.g. strlen, qsort, setjmp, etc...) this eases the porting of FreeType 2 to exotic environments like XFree86 modules/extensions.. also removed many #include <string.h>, #include <stdlib.h>, etc... from the engine's sources where they're not needed..
Werner Lemberg b7b163cb 2002-03-31T18:48:24 * src/sfnt/ttcmap.c: 16bit fixes (0xFFFF -> 0xFFFFU). * src/sfnt/ttcmap0.c: 16bit fixes. (TT_Build_CMaps): Simplify debug messages. (tt_cmap12_char_next): Fix offset. * src/sfnt/ttload.c (TT_Load_Names, TT_Load_CMap): Fix debug messages. (TT_Load_OS2): 16bit fix.
David Turner ed54f28e 2002-03-22T17:09:52 various fixes to the FT_CMaps support
David Turner fd88e7c7 2002-03-22T15:02:38 * include/freetype/internal/ftobjs.h, src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h: updated the SFNT charmap support to use FT_CMaps
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 a890c29c 2002-03-22T12:55:23 * include/freetype/internal/ftstream.h, src/base/ftstream.c, src/cff/cffload.c, src/pcf/pcfread.c, src/sfnt/ttcmap.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c, src/sfnt/ttpost.c, src/sfnt/ttsbit.c, src/truetype/ttgload.c, src/truetype/ttpload.c, src/winfonts/winfnt.c: changed the definitions of stream macros. Examples: NEXT_Byte => FT_NEXT_BYTE NEXT_Short => FT_NEXT_SHORT NEXT_UShortLE => FT_NEXT_USHORT_LE READ_Short => FT_READ_SHORT GET_Long => FT_GET_LONG etc.. also introduced the FT_PEEK_XXXX functions..
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...
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 28ea6f67 2002-03-05T16:12:57 * src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name), src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so that it accepts broken fonts like "foxjump.ttf", which made FreeType crash when trying to load them. Also improved the name table parser to be able to load Windows-encoded entries before Macintosh or Unicode ones, since it seems some fonts don't have reliable values here anyway.
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 )
David Turner c03d9cf5 2002-02-27T23:10:19 * src/sfnt/ttload.c (TT_Load_Names): simplifying and securing the names table loader. Invalid individual name entries are now handled correctly. This allows the loading of very buggy fonts like "foxjump.ttf" without allocating tons of memory and causing crashes..

Fixed freeing of arrays in case of unsuccessful loads. Added support for loading format 8, 10, and 12 cmaps. (TT_CharMap_Free): Added support for freeing format 8, 10, and 12 cmaps. (code_to_index4): Small improvement. (code_to_index6): Ditto. (code_to_index8_12, code_to_index10): New functions. * src/sfnt/ttload.c (TT_Load_Metrics_Header): Updated to new structure. (TT_Load_CMap): Ditto. * src/sfnt/sfobjs.c (tt_encodings): Add MS UCS4 table (before MS Unicode). * src/type1/t1driver.c (t1_get_name_index): Fix compiler warning.
Werner Lemberg 36af3ea6 2001-07-17T12:37:54 * include/freetype/internal/psaux.h (PS_Table): Use FT_Offset for `cursor' and `capacity'. * src/psaux/psobjc.c (reallocate_t1_table): Use FT_Long for second parameter. (PS_Table_Add): Use FT_Offset for `new_size'. * src/base/ftsynth.c: Include ftcalc.h unconditionally.

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.

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 d3c8e064 2000-12-04T22:53:55 - updating the header inclusion scheme to use <ft2build.h> by default.. - created "builds/devel" to hold developer builds options for both Win32 and Unix - fixed a bug in the winfonts driver, where the glyph image format wasn't set correctly..

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
David Turner 54e75749 2000-11-04T02:52:02 defining new types to hold "internal" fields of public objects: FT_Face_Internal, FT_Size_Internal, FT_Slot_Internal these contain some fields that may change between releases of FreeType, without affecting the size of FT_FaceRec, FT_SizeRec, FT_GlyphSlotRec, etc.., which means that drivers wouldn't need to be recompiled if we only add new fields to an internal structure.. I plan to hack a few things related to the auto-hinter and I need this move to ensure that we will not break binary compatibility between 2.0 and 2.1 :-) - 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
David Turner 24d7024c 2000-08-17T01:09:06 added draft "psaux" code the t1 driver now reads the complete font matrix and applies it (some fonts do not work properly without hinting though...)
Werner Lemberg b1dd3535 2000-07-31T22:51:00 Added autoconf tests FT_MUNMAP_DECL and FT_MUNMAP_PARAM to fix some devils. Updating unix/ftsystem.c accordingly. More warning fixes.
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 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 aa8c7da0 2000-07-04T03:37:18 Don't use -lefence in the demo Makefile. Added C++ guards in ftmodule.h Fix error check in ftglyph.c Formatting; adding copyrights; fixing documentation
David Turner d18388e4 2000-07-03T15:00:49 fixed a few 64-bit related bugs in "sfnt/ttload.c" and "base/ftstream.c" Note that "TT_PCLT" was incorrectly defined in <freetype/tttables.h>

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 7a4fda88 2000-06-13T23:21:00 The next round of formatting, checking documentation, etc.
