Werner Lemberg ffee64af 2013-08-26T12:55:48 Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all. With this change, all font loading routines emit a tracing message at level 1, making it easier to select tracing output (for example using F2_DEBUG="any:1 afhints:7 aflatin:7"). * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message. * src/cff/cffdrivr.c (cff_glyph_load): Ditto. * src/cff/cffgload.c (cff_decoder_prepare): Improve tracing messages. * src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing message. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. * src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
suzuki toshiya 1749d8bc 2012-01-17T02:00:24 Remove trailing spaces.
Werner Lemberg 910b544a 2011-11-30T13:08:28 [type1] Remove casts. * src/type1/t1driver.c (t1_driver_class): Remove all casts and update affected functions. * src/type1/t1gload.c, src/type1/t1gload.h, src/type1/t1objs.c: Updated for t1driver changes. src/type1/t1objs.h (T1_Driver): Remove unused typedef. Updated for t1driver changes.
Ken Sharp 63e7aac3 2010-02-10T07:13:27 Really fix Savannah bug #28678 (part 2). Since we consider `sbw' for the horizontal direction only, we still have to synthesize vertical metrics if the user wants to use the vertical writing direction. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is set.
Ken Sharp 980b76ea 2010-02-10T07:02:43 Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of *one* direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it.
Ken Sharp f19e46f3 2010-01-27T10:04:50 Fix Savannah bug #28678. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_load_glyph): Handle vertical metrics correctly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle vertical metrics correctly.

suzuki toshiya f2647dda 2009-09-26T00:48:37 [cache, psaux, type1] Fix for multi build.
Werner Lemberg 11cb8c36 2009-06-22T16:56:47 Use 16.16 format while parsing Type 1 charstrings. This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H. (t1_build_add_point): Always convert fixed to integer. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Use 16.16 format everywhere (except for large integers followed by a `div'). [CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate code uncoditionally. Add support for random numbers and update remaining code accordingly; this should work now. (t1_operator_seac): Updated. * src/psaux/pshrec.c: Include FT_INTERNAL_CALC_H. (ps_hints_t1stem3, t1_hints_stem): Updated. * src/cid/cidgload.c: Include FT_INTERNAL_CALC_H. (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL], (cid_face_compute_max_advance, cid_slot_load_glyph): Updated. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String) [FT_CONFIG_OPTION_INCREMENTAL], (T1_Get_Advances, T1_Load_Glyph): Updated. * src/type1/t1load.c: Include FT_INTERNAL_CALC_H. * src/type1/t1objs.c (T1_Face_Init): Updated.

Also provide 'fast loaders' for the TrueType, Type1 and CFF font drivers (more to come later) * autogen.sh: add checks for minimum version of the 'autotools' stuff.
Werner Lemberg 913a3650 2006-11-19T09:19:17 Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'.
Werner Lemberg a4d6a1c8 2006-07-19T09:54:56 Move creation of field `buildchar' of T1_DecoderRec out of `t1_decoder_init' and let the caller of `t1_decoder_init' take care of it. Call the finisher for T1_Decoder in `cid_face_compute_max_advance' and `T1_Compute_Max_Advance'. * freetype2/include/freetype/internal/psaux.h (T1_DecoderRec): Remove field `face', add `len_buildchar'. * freetype2/include/freetype/internal/t1types.h (T1_FaceRec): Add field `buildchar'. * freetype2/src/cid/cidgload.c (cid_face_compute_max_advance): Call finisher for T1_Decoder.

(t1_decoder_done): Remove deallocation of field `buildchar'. * freetype/src/type1/t1gload.c (T1_Compute_Max_Advance): Initialize T1_Decoder's `buildchar' and `len_buildchar'; call finisher for T1_Decoder. (T1_Load_Glyph): Initialize T1_Decoder's `buildchar' and `len_buildchar'; make sure to call finisher for T1_Decoder even in case of error. * freetype2/src/type1/t1load.c (T1_Open_Face): Allocate new field `buildchar' of T1_FaceRec. * freetype2/src/type1/t1objs.c (T1_Face_Done): Free new field `buildchar' of T1_FaceRec.
David Turner 281679de 2006-05-17T13:34:21 * include/freetype/internal/tttypes.h, src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c, src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c, src/type1/t1gload.c: this is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glypn vector themselves and the auto-fitter. note that we've started using inline assembler with GCC to implement FT_MulFix, given that this function is so damn important for the engine's performance. the resulting speed-up is about 25%.

Werner Lemberg b442ca17 2003-04-23T15:50:27 Cleanups.
Graham Asher 46960df7 2003-02-13T17:49:27 The incremental interface now passes the old metrics when asking for replacement metrics so that they can be modified, not just replaced. For example, CFF fonts need this.
Werner Lemberg 6b5c669b 2002-09-05T15:10:54 * src/cid/cidobjs.c (CID_Size_Init): Renamed to... (cid_size_init): This. * src/psaux/psobjs.c (T1_Builder_Add_Point1): Renamed to... (t1_builder_add_point1): This. Updated all affected code. * src/pshinter/pshalgo3.c (psh3_hint_align): Fix compiler warnings. * src/type1/t1gload.c (T1_Compute_Max_Advance): Ditto. Formatting, minor doc fixes.
David Turner d1245c0d 2002-08-27T22:34:20 updating sources to support the new FT_LOAD_TARGET_ constants to support target-specific hinting
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 3c403e4c 2002-08-06T21:47:40 Some formatting. * src/cff/cffcmap.c: Remove compiler warnings. * src/cache/ftccache.c, src/cache/ftccache.i, src/pfr/pfrload.c, src/pfr/pfrgload.c: s/index/idx/. * src/cff/cffload.c: s/select/fdselect/. * src/raster/ftraster.c: s/wait/waiting/.
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 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.

Not that it doesn't support embedded bitmaps or kerning tables for now.. * include/freetype/internal/ftmemory.h: adding the FT_MEM_ZERO and FT_ZERO macros * include/freetype/internal/ftstream.h: adding the FT_NEXT_OFF3, FT_NEXT_UOFF3, FT_NEXT_OFF3_LE and FT_NEXT_UOFF3_LE to parse in-memory 24-bit integers.
David Turner 11cfdd04 2002-04-17T09:37:59 fixed max advance width computation within T1 driver
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 efa99615 2002-04-01T22:01:46 * src/type1/t1driver.c, src/type1/t1parse.c: 16bit fixes. formatting, copyright updates
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 29644179 2002-02-28T18:59:37 still more logical transformations. This time, some public API headers have been touched, while keeping everything backwards-compatible.. * include/freetype/t1tables.h: re-naming structure types. This done basically: typedef T1_Struct_ { } T1_Struct; becomes: typedef PS_StructRec_ { } PS_StructRec, *PS_Struct; typedef PS_StructRec T1_Struct; /* backwards-compatibility */ hence, we increase the coherency of the source code by effectuively using the 'Rec' prefix for structure types..
David Turner 4e7eeeec 2002-02-28T16:10:29 yet another logical transformation of the internals to make them more consistent and understandable.. mainly, changing things like PS_Table => PS_TableRec + *PS_Table

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..
Werner Lemberg e274cfd3 2001-03-04T21:53:08 * src/autohint/ahtypes.h (AH_Hinter): Add elements `disable_horz_edges', `disable_vert_edges'. * src/autohint/ahhint.c (ah_hint_edges_3, ah_hinter_hint_edges): Use them (and remove static variables with the same names). * src/pcf/pcfutil.c (BitOrderInvert): Add `const'. * docs/glnames.py: Updated to latest pstables.h changes. * src/psnames/pstables.h: Add more `const'. * src/pcf/pcfutil.c: Ditto. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixing typo (FT_Glyph_Done -> FT_Done_Glyph). * include/freetype/ttnameid.h: Added some new Microsoft language codes and LCIDs as found in Office Xp. * builds/hurd/detect.mk: New file.

Werner Lemberg dc72aff4 2000-11-04T08:33:38 Finishing David's latest changes (there were some errors in it).
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

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..
Werner Lemberg 768c9561 2000-07-03T07:09:09 Formatting. Fixing some tracing messages.
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 e82a82af 2000-06-22T00:26:11 small bugfix in the "seac" code
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.
