Werner Lemberg 04edbbda 2014-11-25T10:21:13 */*: s/Invalid_Argument/Invalid_Face_Handle/ where appropriate.
Werner Lemberg b24e8ba2 2014-11-25T08:30:49 [Savannah bug #43682] Add/remove `void' casts to some functions. We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it.
Werner Lemberg 7e4b0fbf 2013-11-06T07:14:49 [truetype] Improve emulation of vertical metrics. This commit also improves the start values of vertical phantom points. Kudos to Greg Hitchcock for help. * src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass `yMax' value. Replace code with fixed Microsoft definition. (tt_get_metrics): Updated. (TT_LOADER_SET_PP): Add explanation how to initialize phantom points, taken from both the OpenType specification and private communication with Greg (which will eventually be added to the standard). Fix horizontal position of `pp3' and `pp4'. * src/truetype/ttgload.h: Updated. * src/truetype/ttdriver.c (tt_get_advances): Updated. * docs/CHANGES: Updated.
Werner Lemberg f04951af 2013-05-17T13:51:07 [truetype] Add `interpreter-version' property. This makes the option TT_CONFIG_OPTION_SUBPIXEL_HINTING controllable at runtime. * src/truetype/ttdriver.c: Include FT_TRUETYPE_DRIVER_H. (tt_property_set, tt_property_get): Fill templates. * src/truetype/ttobjs.h (TT_DriverRec): Add `interpreter_version' member. Remove unused `extension_component' member. * src/truetype/ttgload.c: Include FT_TRUETYPE_DRIVER_H. (tt_get_metrics, TT_Hint_Glyph, TT_Process_Simple_Glyph, compute_glyph_metrics, tt_loader_init): Use `interpreter_version'. * src/truetype/ttinterp.c: Include FT_TRUETYPE_DRIVER_H. (SUBPIXEL_HINTING): New macro to check `interpreter_version' flag. Update all affected functions to use it. Use TT_INTERPRETER_VERSION_XXX where appropriate. * src/truetype/ttobjs.c: Include FT_TRUETYPE_DRIVER_H. (tt_driver_init): Initialize `interpreter_version'. * src/truetype/ttsubpix.c: Include FT_TRUETYPE_DRIVER_H. Use TT_INTERPRETER_VERSION_XXX where appropriate.
Werner Lemberg cd888753 2013-05-12T15:08:57 [truetype] Add framework for TrueType properties. * src/truetype/ttdrivr.c: Include FT_SERVICE_PROPERTIES_H. (tt_property_set, tt_property_get): New functions, still empty. Define `tt_service_properties' service. Update `tt_services'. * src/truetype/ttpic.h: Include FT_SERVICE_PROPERTIES_H. (TT_SERVICE_PROPERTIES_GET): New macro. (TTModulePIC): Add `tt_service_properties'.
Werner Lemberg f6aa089f 2013-05-10T07:58:47 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code.
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.
Werner Lemberg 0c633e3f 2012-08-27T07:43:28 [sfnt, truetype] More renamings for orthogonality. * src/sfnt/sfdriver.c, src/sfnt/sfntpic.h, src/sfnt/ttcmap.c, src/truetype/ttdriver.c, src/truetype/ttpic.h: s/FT_SFNT_/SFNT_/, s/FT_TT_/TT_/, s/GET_CMAP_INFO_GET/CMAP_INFO_GET/.
Werner Lemberg 59874450 2012-07-29T13:15:53 Formatting, comment fixes.
Werner Lemberg 6b5b6f39 2012-02-24T12:26:25 Prepare source code for amalgamation (6/6). * src/cff/cffdrivr.c: s/Load_Glyph/cff_glyph_load/. * src/cid/cidload.c: s/parse_font_matrix/cid_parse_font_matrix/. s/t1_init_loader/cid_init_loader/. s/t1_done_loader/cid_done_loader/. * src/pxaux/t1cmap.c: s/t1_get_glyph_name/psaux_get_glyph_name/. * src/truetype/ttdriver.c: s/Load_Glyph/tt_glyph_load/. * src/type1/t1load.c: s/parse_font_matrix/t1_parse_font_matrix/.
suzuki toshiya 226f3619 2012-01-14T06:40:03 Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6. Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET take no arguments but derefer the variable named `library' internally. * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and set it if non-NULL driver is passed. * src/truetype/ttdriver.c (tt_get_interface): Ditto. * src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library' under PIC configuration, and set it if non-NULL module is given. * src/psnames/psmodule.c (psnames_get_interface): Ditto.
Werner Lemberg c52f44d4 2011-11-30T10:46:53 Whitespace.
Steven Chu b0962ac3 2011-07-16T09:12:42 [truetype] Fix metrics on size request for scalable fonts. * src/truetype/ttdriver.c (tt_size_request): Fix copying metrics from TT_Size to FT_Size if scalable font.
Behdad Esfahbod 8c82ec5b 2011-04-21T08:21:37 Always ignore global advance. This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, deprecated, and ignored. The new behavior is what every major user of FreeType has been requesting. Global advance is broken in many CJK fonts. Just ignoring it by default makes most sense. * src/truetype/ttdriver.c (tt_get_advances), src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics, tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph), src/truetype/ttgload.h: Implement it. * docs/CHANGES: Updated.
suzuki toshiya d9145241 2010-02-05T02:58:24 Prevent NULL pointer dereference passed to FT_Module_Requester.
Werner Lemberg 2a33275e 2010-01-05T10:27:15 Fix Savannah bug #28395. * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Loada_Glyph): Don't check `num_glyphs' if incremental interface is used.
Oran Agra 2e7a4e9b 2009-04-05T18:03:02 Position Independent Code (PIC) support in truetype driver. * include/freetype/internal/services/svmm.h add macros to init instances of FT_Service_MultiMastersRec. * include/freetype/internal/services/svttglyf.h add macros to init instances of FT_Service_TTGlyfRec. * src/truetype/ttdriver.h declare tt_driver_class using macros from ftdriver.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/truetype/ttdriver.c when FT_CONFIG_OPTION_PIC is defined the following structs: tt_service_gx_multi_masters, tt_service_truetype_glyf, tt_driver_class and tt_services array, will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from ttpic.h in order to access them from the pic_container. * src/truetype/ttobjs.c change trick_names array to be PIC-compatible by being a two dimentional array rather than array of pointers. New Files: * src/truetype/ttpic.h declare struct to hold PIC globals for truetype driver and macros to access them. * src/truetype/ttpic.c implement functions to allocate, destroy and initialize PIC globals for truetype driver. * src/truetype/truetype.c add new file to build: ttpic.c. * src/truetype/jamfile add new files to FT2_MULTI build: ttpic.c.
Werner Lemberg 86e041b5 2009-03-21T08:51:44 Remove redundant header inclusions. This covers many Ghostscript Coverity issues. * src/*: Do it.
Suzuki, Toshiya (鈴木俊哉) 759c07d1 2009-01-09T11:11:53 load_flags of FT_Get_Advance(), FT_Get_Advances() and backends are declared as FT_Int32 to match the flags of FT_Load_Glyph()
Suzuki, Toshiya (鈴木俊哉) a7c00b79 2009-01-09T07:21:16 load_flags of FT_Get_Advance(), FT_Get_Advances() and backends are declared as FT_UInt32 for 16-bit platforms
Werner Lemberg b972a2a2 2008-12-11T08:55:48 Generalize the concept of `tricky' fonts by introducing FT_FACE_FLAG_TRICKY to indicate that the font format's hinting engine is necessary for correct rendering. At the same time, slightly modify the behaviour of tricky fonts: FT_LOAD_NO_HINTING is now ignored. To really force raw loading of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used. Finally, tricky TrueType fonts always use the bytecode interpreter even if the patented code is used. * include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY): New macros. * src/truetype/ttdriver.c (Load_Glyph): Handle new load flags semantics as described above. * src/truetype/ttobjs.c (tt_check_trickyness): New function, using code of ... (tt_face_init): This function, now simplified and updated to new semantics. * src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky fonts. * docs/CHANGES: Document it.
Werner Lemberg b211651a 2008-09-12T16:27:48 * autogen.sh, builds/unix/configure.raw, include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor beautifying. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h, include/freetype/ftlcdfil.h: Protect against FreeType 1. Some other minor fixes. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. Formatting, documentation improvements.
David Turner 28534d61 2008-09-01T21:35:21 * include/freetype/ftadvanc.h, src/base/ftadvanc.c, include/freetype/config/ftheader.h, include/freetype/freetype.h, src/base/Jamfile, src/base/rules.mk, src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffgload.h, src/truetype/ttdriver.c, src/truetype/ttgload.h, src/truetype/ttgload.c, src/type1/t1driver.c, src/type1/t1gload.h, src/type1/t1gload.c: Add a new header named FT_ADVANCES_H declaring some new APIs to extract the advances of one or more glyphs without necessarily loading their outlines. 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 f6c120f8 2007-06-11T04:55:58 * docs/CHANGES: Document FT_Face_CheckTrueTypePatents). Formatting, reformulations.
David Turner 84c6f881 2007-06-10T20:51:04 * include/freetype/config/ftoption.h: clarify documentation regarding unpatented hinting * include/freetype/freetype.h, src/base/ftpatent.c, src/truetype/ttdriver.c, include/freetype/internal/services/svttglyf.h, modules.cfg,: include/freetype/internal/ftserv.h,: Fonts without a cmap must be handled correctly by FreeType (anything Adding the FT_Face_CheckTrueTypePatents API to FT_FREETYPE_H, it is implemented by the optional src/base/ftpatent.c
Werner Lemberg 8c4120d0 2007-01-15T06:42:40 Fix various compiler warnings. * src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h, src/cff/cffobjs.c (cff_size_request), src/type42/t42objs.h: s/index/strike_index/. * src/base/ftobjs.c (FT_Match_Size): s/index/size_index/. * src/gxvalid/gxvmorx5.c (gxv_morx_subtable_type5_InsertList_validate): s/index/table_index/. * src/truetype/ttinterp.c (Compute_Point_Displacement), src/pcf/pcfread.c (pcf_seek_to_table_type): Avoid possibly uninitialized variables.
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'.
David Turner 6aa260ce 2006-08-25T22:45:13 support for "automatic unpatented hinting" added we still need to determine the list of "trick" CJK fonts that are going to toggle the bytecode interpreter instead of the auto-hinter
David Turner 6c71c6b9 2006-02-25T12:49:40 * include/freetype/config/ftoption.h, src/autofit/afcjk.c, src/base/ftobjs.c, src/base/ftutil.c, src/cff/cffobjs.c, src/psaux/afmparse.c, src/sfnt/ttbdf.c, src/tools/apinames.c, src/truetype/ttdriver.c: solved compiler warnings as well as C++ compilation problems
Werner Lemberg 5edafed1 2006-02-22T08:23:35 Clean-ups, copyright years, formatting.
David Turner 0b5dc4df 2006-02-21T22:36:23 * include/freetype/ftmodapi.h, include/internal/ftserv.h, include/internal/services/svtteng.h, src/base/ftobjs.c, src/truetype/ttdriver.c: adding a new API named FT_Get_TrueType_Engine_Type to determine wether we have a patented, unpatented or unimplemented TrueType bytecode interpreter. the FT_Get_Module_Flags API was removed consequently.
David Turner cda2d957 2006-02-16T22:45:31 * builds/amiga/src/base/ftsystem.c, devel/ftoption.h include/freetype/ftcache.h, include/freetype/ftoutln.h, include/freetype/cache/ftccache.h, include/freetype/cache/ftccmap.h, include/freetype/config/ftoption.h, include/freetype/internal/ftcalc.h, include/freetype/internal/ftdriver.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, include/freetype/internal/ftrfork.h, include/freetype/internal/psaux.h, include/freetype/internal/sfnt.h, include/freetype/internal/t1types.h, include/freetype/internal/tttypes.h, src/base/ftcalc.c, src/base/ftdbgmem.c, src/base/ftobjs.c, src/base/ftsystem.c, src/base/ftutil.c, src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h, src/cache/ftccmap.c, src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/psaux/psauxmod.c, src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: massive changes to the internals to respect the internal object layouts and exported functions of FreeType 2.1.7. Note that the cache sub-system cannot be fully retrofitted, unfortunately.
Wu, Chia-I (吳佳一) 0d565fdc 2006-02-15T07:44:31 * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove unused `max_points' and `max_contours'. * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update. * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused `max_components'. * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused `loadSize' and `loadStack'. * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context), src/sfnt/ttload.c (tt_face_load_maxp): Update. * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c (sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not defined. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions. (finally!) For most OpenType tables, `tt_face_load_xxxx' simply loads the table and `face->root' is set later in `sfnt_load_face'. Here, we try to make this work for _all_ tables. * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and then exit. Error handling or setting face->root is done later in `sfnt_load_face'. Pretty trace messages. * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. Mac bitmap-only fonts are not scalable. Check that `face->header.Units_Per_EM' is not zero. (LOAD_, LOADM_): Pretty trace messages. * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from `eblc'. * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c (load_format_20, load_format_25, tt_face_get_ps_name): Use face->max_profile.numGlyphs, instead of face->root.num_glyphs.

Wu, Chia-I (吳佳一) bcc438b1 2006-01-23T14:12:40 * include/freetype/freetype.h (FT_Select_Size): Rename the second argument from `idx' to `strike_index'. (FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of this enum. * include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH, FT_REQUEST_HEIGHT): New macros to get the width and height of a request, in fractional pixels. * include/freetype/internal/ftobjs.h (FT_Select_Metrics, FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics, FT_Request_Metrics): New base functions to set the font metrics. They were part of FT_Select_Size/FT_Request_Size and are made independent functions so that metrics are not set again and again. * src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set only when driver's size_select/size_request is NULL. That is, drivers should set the metrics themselves. (FT_Match_Size): Round before matching. This was what we did and it does cause some problems without rounding. * src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c (tt_size_select): Set the font metrics. s/index/strike_index/. The scaled metrics are always preferred over strikes' metrics, even when some strike is selected. This is done because the strikes' metrics are not reliable, e.g., the sign of the descender is wrong for some fonts. * src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c (tt_size_request): Set the font metrics. Call cff_size_select/tt_size_select when some strike is matched. * src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c, src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c, src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c: Set the font metrics. s/index/strike_index/. * src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these files were committed. Just a catch-up. (PS_Conv_ToFixed): Remove the `goto'. (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little. * src/sfnt/ttsbit.c (tt_face_load_sbit_strikes, tt_face_load_strike_metrics), src/sfnt/ttsbit0.c (tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The advertised metrics in `available_sizes' are different from those actually used.
Werner Lemberg f1c2b91e 2006-01-13T14:53:28 Formatting, copyright year updates. Decorate long constants with `L' and `UL' where appropriate.
Wu, Chia-I (吳佳一) fa7d6ab2 2006-01-13T12:21:31 * include/freetype/internal/sfnt.h (SFNT_Interface): New method `load_strike_metrics' used to load the strike's metrics. * src/sfnt/sfdriver.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: New function `tt_face_load_strike_metrics'. * src/pfr/pfrobjs.c (pfr_face_init): Set FT_Bitmap_Size correctly. * src/winfonts/winfnt.c (FNT_Face_Init): Use `nominal_point_size' for nominal size unless it is obviously incorrect. * include/freetype/freetype.h (FT_Bitmap_Size): Update the comments on FNT driver. Introduce new size selection interface. * include/freetype/internal/ftdriver.h (struct FT_Driver_ClassRec_): Replace `set_char_sizes' and `set_pixel_sizes' by `request_size' and `select_size'. * include/freetype/freetype.h (FT_Select_Size, FT_Size_Request_Type, FT_Size_Request, FT_Request_Size, FT_Select_Size), src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): API additions to export the new size selection interface. * src/base/ftobjs.c (FT_Set_Char_Size, FT_Set_Pixel_Sizes): Use `FT_Request_Size'. * include/freetype/internal/ftobjs.h (FT_Match_Size), src/base/ftobjs.c (FT_Match_Size): New function to match a size request against `available_sizes'. Drivers supporting bitmap strikes can use this function to implement `request_size'. * src/bdf/bdfdrivr.c, src/cid/cidobjs.c, src/cid/cidobjs.h, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type1/t1objs.h, src/type42/t42drivr.c, src/type42/t42objs.c, src/type42/t42objs.h, src/winfonts/winfnt.c: Update to new size selection interface. * src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffobjs.c, src/cff/cffobjs.h, src/truetype/ttdriver.c, src/truetype/ttgload.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: Update to new size selection interface. Make `strike_index' FT_ULong and always defined. Use `load_strike_metrics' provided by SFNT interface.
Wu, Chia-I (吳佳一) 15c1f5d3 2005-08-20T08:17:44 * src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of ttmetrics here. TrueType fonts with only sbits always have ttmetrics.valid set to false. * src/truetype/ttgload.c (TT_Load_Glyph): Check that ttmetrics is valid before loading outline glyph. * src/cache/ftcimage.c (FTC_INode_New): Fix a memory leak.
Wu, Chia-I (吳佳一) 0142e6af 2005-08-16T01:54:59 * src/truetype/ttinterp.c, src/truetype/ttinterp.h: Remove original TT_Done_Context and rename TT_Destroy_Context to TT_Done_Context with slight changes. * src/truetype/ttobjs.h (tt_slot_init): New function. * src/truetype/ttobjs.c (tt_driver_init): Initialize execution context here. (tt_slot_init): New function to create extra points for the internal glyph loader. We then use it directly, instead of face's glyph loader, when loading glyph. * src/truetype/ttdriver.c: Use tt_slot_init for glyph slot initialization. (TT_Load_Glyph): Load flag dependencies are handled here. Return error if size is NULL. * src/truetype/ttgload.c: Heavy cleanup and refactor. (TT_Hint_Glyph): New funcion to hint a zone, prepared by caller. (TT_Process_Simple_Glyph): Use loader->pp's instead of recalculating. Use TT_Hint_Glyph. No need to save/restore loader->stream before/after TT_Vary_Get_Glyph_Deltas now. (TT_LOADER_SET_PP): New macro to calculate and set the four phantom points. (TT_Process_Composite_Component, TT_Process_Composite_Glyph, load_truetype_glyph): Refactor load_truetype_glyph into these three functions. Never set exec->glyphSize to 0. (close #13107) Forget glyph frame before calling TT_Process_Simple_Glyph. (TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into these three functions. Set various fields of `glyph' here, instead of in load_truetype_glyph and compute_glyph_metrics.
Werner Lemberg 8e3fc5ea 2005-08-03T21:17:53 * src/otvalid/otvcommn.h: Remove dead code. Formatting.

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...

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.

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 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.
