Werner Lemberg 441b3f38 2014-07-13T02:28:14 [truetype] Improve handling of buggy `prep' tables. In case of an error in the `prep' table, no longer try to execute it again and again. This makes FreeType handle endless loops in buggy fonts much faster. * src/truetype/ttobjs.h (TT_SizeRec): The fields `bytecode_ready' and `cvt_ready' are now negative if not initialized yet, otherwise they indicate the error code of the last run. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_done_bytecode, tt_size_init_bytecode, tt_size_ready_bytecode, tt_size_init, tt_size_done, tt_size_reset): Updated. * src/truetype/ttgload.c (tt_loader_init): Updated. * src/truetype/ttinterp.c (TT_RunIns): Force reexecution of `fpgm' and `prep' only if we are in the `glyf' table.
Werner Lemberg 063ee6b1 2013-11-24T00:19:17 [truetype]: Add tricky font names `hkscsiic.ttf' and `iicore.ttf'. * src/truetype/ttobjs.c (TRICK_NAMES_MAX_CHARACTERS, TRICK_NAMES_COUNT): Updated. (trick_names): Add family name for the two fonts.
Werner Lemberg d689d1cf 2013-08-29T17:53:40 Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.
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 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 a2c7eb18 2013-02-07T19:49:12 * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables. BTW, Greg agrees that the OpenType specification is missing the list of GS variables which will always be reset to the default values after the `prep' table has been executed.
Werner Lemberg bfcc375b 2013-02-06T08:47:29 * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points. Up to now, we simply took a snapshot of the Graphics State after the `prep' table has been executed, and right before a glyph's bytecode was run it got reloaded. However, as Greg Hitchcock has told us in private communication, reference points get reset to zero in the MS rasterizer and we follow in due course. While reasonable, this is undocumented behaviour. Most notably, this fixes the rendering of Arial's `x' glyph in subpixel hinting mode.
Werner Lemberg 87dc86d6 2013-01-24T08:39:43 [truetype] Revert change from 2013-01-22. FreeType's `height' value is the baseline-to-baseline distance... * src/truetype/ttobjs.c (tt_size_reset): Undo.
Werner Lemberg e0469372 2013-01-22T11:07:07 [truetype] Fix font height. * src/truetype/ttobjs.c (tt_size_reset): The Windows rendering engine uses rounded values of the ascender and descender to compute the TrueType font height.
Alexei Podtelezhnikov 65d65721 2012-12-10T06:59:29 [truetype] Scale F_dot_P down. The dot product between freeVector and projVector or cosine of the angle between these FT_F2Dot14 unit vectors used to be scaled up by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. This patch scales the value down by 2^14 instead, which simplifies its use throughout the bytecode interpreter. This does not lead to the loss of precision because the lower bits are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. These vectors are stored as (0x4000,0) and (0x2666,0x3333) after rounding and F_dot_P is assigned 0x26660000. The lower bits were already lost while rounding the unit vector components. Besides code simplification, this change can lead to better performance when FT_MulDiv with the scaled-down F_dot_P is less likely to use the costly 64-bit path. We are not changing the type of F_dot_P to FT_F2Dot14 at this point. * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 bits and modify its use accordingly. (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify the use of F_dot_P field. * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary assignment of F_dot_P to its theoretical maximum in case we decide to scale back its type later.
Werner Lemberg 4d3a1e6c 2012-12-05T06:32:57 Formatting.
Alexei Podtelezhnikov 4ae9cbb0 2012-12-01T23:36:02 [truetype, type1] Revise the use of FT_MulDiv. * src/truetype/ttgxvar.c: Updated. * src/truetype/ttobjs.c: Updated. * src/type1/t1load.c: Updated.
suzuki toshiya 6c7c3de1 2012-06-14T01:38:20 [truetype] Add new versions of NEC FA family to tricky font list. NEC FA family dated in 1996 have different checksum. Reported by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>; see http://lists.gnu.org/archive/html/freetype-devel/2012-06/msg00023.html * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): 4 sets of fpgm & prep table checksums for FA-Gothic, FA-Minchou, FA-RoundedGothicM, FA-RoundedGothicB are added. The family names in sample PDF are truncated, thus the list of the family names in tt_check_trickyness_family() is not updated yet.
Werner Lemberg c52f44d4 2011-11-30T10:46:53 Whitespace.
Werner Lemberg 70cf8c5e 2011-11-26T20:09:39 Improve tracing. * src/bdf/bdfdrivr.c (BDF_Face_Done), src/pcf/pcfdrivr.c (PCF_Face_Done): Remove tracing message. * src/bdf/bdfdrivr.c (BDF_Face_Init), src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/pfr/pfrobjs.c (pfr_face_init), src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c (tt_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init), src/winfonts/winfnt.c (FNT_Face_Init): Add `greeting' message. * src/sfnt/sfobjs.c (sfnt_open_font), src/type42/t42objs.c (T42_Open_Face): Improve tracing.
Werner Lemberg 930e9bf8 2011-11-26T13:38:26 Add new error code FT_Err_Missing_Module. Previously, FreeType misleadingly returned FT_Err_Unknown_File_Format if a module was missing (or a test was missing completely). * include/freetype/fterrdef.h (FT_Err_Missing_Module): Define. * src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c (tt_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init, T42_Driver_Init): Updated. * src/type1/t1afm.c (T1_Read_Metrics), src/type/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Remove now redundant test for `psaux'.
Werner Lemberg f4b63326 2011-07-03T11:24:46 Fix previous commit. We want to unset FT_FACE_FLAG_SCALABLE only if there are bitmap strikes in the font. * src/truetype/ttobjs.c (tt_face_init): Implement it. * docs/CHANGES: Updated.
Just Fill Bugs 07598339 2011-07-02T18:41:36 Fix Savannah bug #33246. * src/truetype/ttobjs.c (tt_check_single_notdef): New function. (tt_face_init): Use it to test FT_FACE_FLAG_SCALABLE.
Daniel Zimmermann 3ad8f355 2011-05-24T06:22:32 Reduce warnings for MS Visual Studio 2010. * src/autofit/afhints.c (af_glyph_hints_get_num_segments, af_glyph_hints_get_segment_offset) [!FT_DEBUG_AUTOFIT]: Provide return value. * src/cff/cffgload.c (cff_slot_load): Add cast. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Use proper loop variable type.
suzuki toshiya 58cb3593 2011-05-01T00:47:43 [truetype] Recalculate the sfnt table checksum always. * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate the sfnt table checksum even if non-zero value is writte in the TrueType font header. Some bad PDF generators write wrong values. For detail, see examples and benchmark tests of the latency by recalculation: http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00091.html http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00096.html
suzuki toshiya 1e89d15a 2011-04-30T17:55:57 [truetype] Register a set of tricky fonts, NEC FA family. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Add 8 checksum sets for NEC FA family. For the tricky fonts without some tables (e.g. NEC FA fonts lack cvt table), extra check is added to assure that 0-length table in the registry is not included in the font.
suzuki toshiya 10385e37 2011-04-30T17:49:45 Remove unrequired `else' from ttobjs.c::tt_get_sfnt_checksum().
suzuki toshiya 89208861 2011-04-30T00:11:07 [truetype] Fix a bug in the sfnt table checksum getter. * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the return value of face->goto_table() correctly.
suzuki toshiya 86b7b2f6 2011-04-26T03:46:12 [truetype] Revert the reordering of trickyness checking. Trickyness check by the family name is faster than that by the checksum.
suzuki toshiya abc47aa1 2011-04-25T23:51:04 [truetype] Always check the checksum to identify tricky fonts. Some PDF generators mangle the family name badly, prioritize the check by the sfnt table checksums than the check by the family name. For sample PDF, see http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html * src/truetype/ttobjs.c (tt_check_trickyness): Exchange the order of tt_check_trickyness_family() and tt_check_trickyness_sfnt_ids().
Werner Lemberg 18931a5a 2011-02-01T07:08:43 [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also. * src/truetype/ttgload.c (tt_loader_init): Handle `FT_LOAD_PEDANTIC'. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_init_bytecode, tt_size_ready_bytecode): New argument to handle pedantic mode. * src/truetype/ttobjs.h: Updated.
Werner Lemberg 9871b849 2010-11-22T19:30:41 Some formatting and improvements of comments.
suzuki toshiya 9f5dd61b 2010-11-23T02:47:10 [truetype] Identify the tricky fonts by cvt/fpgm/prep checksums. Some Latin TrueType fonts are still expected to be unhinted. Fix Savannah bug #31645. * src/truetype/ttobjs.c (tt_check_trickyness): Divided to... (tt_check_trickyness_family): this checking family name, and (tt_check_trickyness_sfnt_ids): this checking cvt/fpgm/prep. (tt_get_sfnt_checksum): Function to retrieve the sfnt checksum for specified subtable even if cleared by lazy PDF generators. (tt_synth_sfnt_checksum): Function to calculate the checksum.
Werner Lemberg 6abb9232 2010-09-14T09:02:10 Improve tracing messages. * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing message. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add tracing message. * src/truetype/ttgload.c (tt_loader_init): Add tracing message. * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if glyph doesn't fit into a small bitmap container.
suzuki toshiya 0eb9b1f5 2010-08-28T21:41:16 Force hinting when the font lacks its familyname. In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt stream may lack `name' table because they are not required. Hinting for nameless fonts is safer for PDFs including embedded Chinese fonts. Written by David Bevan, see: http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html http://lists.freedesktop.org/archives/poppler/2010-August/006310.html * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by nameless font is given, TRUE is returned to enable hinting.
suzuki toshiya 8b05b5d8 2010-08-28T21:16:26 Register yet another tricky TrueType font. * src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?', a Kaishu typeface paired with `HuaTianSongTi?' by Huatian Information Industry.
Werner Lemberg 46e05c44 2009-07-17T22:49:34 Fix Savannah bug #23786. * src/truetype/ttobjs.c (tt_size_init_bytecode): Don't reset x_ppem and y_ppem. Otherwise the `*_CVT_Stretched' functions in ttinterp.c get never called. An anonymous guy suggested this change on Savannah, and it seems to be the right solution.
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.
Werner Lemberg 0552a496 2009-02-11T22:59:40 * src/truetype/ttobjs.c (tt_check_trickyness): Add `DFKaiShu'. Reported by David Bevan <dbevan@emtex.com>.
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 d03d856d 2008-10-01T22:39:05 * src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c (cff_face_done), src/pfr/pfrobjs.c (pfr_face_done), src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c (cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done), src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0. Reported by Graham Asher.
Werner Lemberg a2f17cc1 2008-05-17T10:01:45 * docs/CHANGES: Updated. Improve support for WGL4 encoded fonts. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro. (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets): New arrays. (ps_check_wgl_name, ps_check_wgl_unicode): New functions. (ps_unicodes_init): Use them to add additional Unicode mappings.
Werner Lemberg d496b926 2007-12-04T21:49:59 * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to concatenate error codes.
Werner Lemberg 6ff2ff57 2007-05-24T19:39:14 * src/truetype/ttobjs.h (tt_size_ready_bytecode): Move declaration into TT_USE_BYTECODE_INTERPRETER preprocessor block. * src/truetype/ttobjs.c (tt_size_ready_bytecode) [!TT_USE_BYTECODE_INTERPRETER]: Removed. Unused.

David Turner 384be234 2007-01-05T15:32:01 * src/truetype/ttobjs.h, src/truetype/ttobjs.c, src/truetype/ttgload.c: do not allocate interpreter-specific tables in memory if we're not going to load glyphs with it anyway.
David Turner 80658e50 2006-11-28T08:09:20 * src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch * src/smooth/ftgrays.c: remove hard-coded error values, use FreeType ones instead * src/autofit/afhints.c (af_glyph_hints_dump_segments): remove unused variable

David Turner ad830716 2006-09-27T16:20:59 * include/freetype/internal/ftobjs.h, src/truetype/ttobjs.c, src/base/ftobjs.c: fixed a bug in the automatic unpatented hinting support which prevented normal bytecode hinting to work properly * src/autofit/aftypes.h: undefining AF_DEBUG to get rid of traces
David Turner f3050059 2006-09-11T12:00:32 * src/sfnt/sfobjs.c (tt_face_get_name): support some function which report their English names through an Apple Roman (platform,encoding) pair, with language_id != English if the font uses another name entry with language_id == English, it will be selected correctly though. * src/truetype/ttobjs.c: add unpatent-hinting selection for "mingli.ttf"

David Turner 6d79f214 2006-09-01T14:09:35 * src/truetype/ttobjs.c: updated the TrueType loader to recognize a few fonts that require the automatic unpatented loader
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 33f5f249 2006-08-16T16:50:55 * include/freetype/internal/ftgloadr.h, include/freetype/internal/tttypes.h, src/base/ftgloadr.c, src/base/ftobjs.c, src/truetype/ttgload.c, src/truetype/ttinterp.c, src/truetype/ttobjs.c: improvements to native TrueType hinting, this is a first try, controlled by the FIX_BYTECODE macro in src/truetype/ttinterp.c
Wu, Chia-I (吳佳一) f5aa47be 2006-02-14T06:40:10 Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading and parsing code is moved here. Move `tt_face_get_metrics' here from the truetype module.

Hints: (x) & -64 will warn if (x) is not signed.. use (x) & ~63 instead !
Werner Lemberg f4c0b921 2003-09-30T05:39:35 * include/freetype/internal/t1types.h: Don't include FT_INTERNAL_OBJECTS_H but FT_INTERNAL_SERVICE_H. * src/truetype/ttobjs.c: Don't include FT_SERVICE_POSTSCRIPT_NAMES_H.
David Turner b72d8a85 2003-09-29T20:33:37 * include/freetype/internal/services/svpsname.h (added), include/freetype/internal/psnames.h (removed), include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES): added new service to handle glyph name dictionaries, replacing the old internal header named "psnames.h" by "services/svpsname.h" note that this is different from "services/svpostnm.h" which only handles the retrieval of Postscript font name for a given face. (should we merge these two services into a single header ??) * include/freetype/internal/ftserv.h: adding FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally, instead of only within the current module) * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: adding the new base function ft_module_get_service
David Turner 17dd0634 2003-09-21T16:04:05 * include/freetype/internal/ftserv.h, include/freetype/internal/service/svpfr.h, include/freetype/internal/pfr.h, src/base/ftpfr.c: migrating the functions of "ftpfr.h" to the new service-base internal API * src/cff/cffobjs.c, src/cid/cidobjs.c, src/pfr/pfrsbit.c, src/psaux/psobjs.c, src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/truetype/ttobjs.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type42/t42objs.c, src/winfonts/winfnt.c: removing various compiler warnings
Werner Lemberg 2bb6ee32 2003-08-18T08:23:40 Some clean-up.
David Turner 8b6db86b 2003-08-17T22:09:14 * include/freetype/config/ftoption.h, devel/ftoption.h, include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h, src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead, the same effect can be used by setting a debug-hook with FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
Werner Lemberg 43ba0842 2003-06-23T19:26:53 * src/tools/glnames.py: Updated to AGL 2.0. * src/psnames/pstables.h: Regenerated. * include/freetype/cache/ftcglyph.h, include/freetype/ttnameid.h, src/base/ftcalc.c, src/base/fttrigon.c, src/cff/cffgload.c, src/otlayout/otlgsub.c, src/pshinter/pshrec.c, src/psnames/psmodule.c, src/sfnt/sfobjs.c, src/truetype/ttdriver.c: Decorate constants with `U' and `L' if appropriate. * include/freetype/ftmoderr.h: Updated to include recent module additions. * src/pshinter/pshnterr.h (FT_ERR_BASE): Define as `FT_Mod_Err_PShinter'. * src/type42/t42error.h (FT_ERR_BASE): Define as `FT_Mod_Err_Type42'. * src/pshinter/pshrec.h (PS_HINTS_MAGIC): Removed.

Werner Lemberg 73861976 2003-06-05T04:31:05 * include/freetype/internal/ftdriver.h, include/freetype/internal/ftobjs.h, include/freetype/internal/psaux.h, src/cid/cidgload.c, src/psaux/psobjs.c, src/psaux/t1decode.c, src/psaux/psobjs.h, src/pshinter/pshrec.c, src/pshinter/pshalgo.c, src/psnames/psmodule.c, src/raster/ftraster.c, src/sfnt/sfobjs.c, src/smooth/ftgrays.c, src/smooth/ftsmooth.c, src/truetype/ttobjs.c, src/truetype/ttdriver.c, src/truetype/ttgload.c, src/type1/t1afm.c, src/type1/t1gload.c, src/type1/t1gload.h, src/type1/t1load.c, src/type1/t1objs.c, src/type42/t42parse.c, src/type42/t42parse.h: Many casts and slight argument type changes to make it work with a 16bit compiler.
Werner Lemberg a3f4da8e 2003-04-29T13:23:47 Minor cleanups.
Graham Asher 3ea859f6 2003-04-25T11:40:46 Added the unpatented hinting system, which is compiled only if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in ftoption.h
Werner Lemberg b442ca17 2003-04-23T15:50:27 Cleanups.
David Turner b280537b 2003-03-13T21:07:51 * src/base/ftdbgmem.c, docs/DEBUG.TXT: added new environment variables to control memory debugging with FreeType. See the description of "FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX" in DEBUG.TXT * src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c, ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a small memory leak * src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that only happened when trying to resize an array would end in an OOM. * src/smooth/ftgrays.c: removed compiler warnings / volatile bug * src/truetype/ttobjs.c: removed segmentation fault that happened in tight memory environments.
David Turner ba4511b8 2003-02-18T22:25:22 * src/truetype/ttdriver.c, src/truetype/ttobjs.h, src/truetype/ttobjs.c, src/truetype/ttinterp.c, src/base/ftobjs.c: fixing the slight distortion problem that occured due to the latest auto-hinter changes
David Turner 14018b4a 2003-01-12T18:26:10 2003-01-11 David Chester <davidchester@qmx.net> * include/freetype/config/ftoption.h, src/autohint/ahglobal.h, src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahtypes.h: included David Chester's patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX macros to control individual "features". Note that all improvements are enabled by default, but can be tweaked for optimization and testing purpose. The configuration macros will most likely disappear in the short future. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h: fixed a structure field definition to avoid memory overwrites
David Turner 25f845aa 2002-09-09T23:45:29 * src/cache/ftccache.i: fixed a bug that prevented compilation in debug mode of template instantiation * src/cff/cffparse.c: fixed the CFF table loader. It didn't accept empty arrays, and this prevented the loading of certain fonts. * src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to prevent seg fault when hints are provided in an empty glyph !! * include/freetype/ftimage.h: removed incorrect "zft_" definitions and updated constants documentation comments * include/freetype/freetype.h (FT_FaceRec): updating documentation comment. The "descender" value is always *negative*, not positive !
David Turner b08fe2dc 2002-08-27T20:20:29 * massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
Graham Asher ce12182c 2002-08-01T15:29:17 Modified incremental loading interface to be closer to David Turner's preferences. The header freetype.h is not now affected, the interface is specified via an FT_Parameter, the pointer to the interface is hidden in an internal part of the face record, and all the definitions are in ftincrem.h.

Graham Asher 11f0ab7d 2002-07-24T13:58:21 FIX for bug reported by Sven Neumann [sven@gimp.org] on the FreeType development forum: "If FT_CONFIG_OPTION_INCREMENTAL is undefined (this is the default), the TrueType loader crashes in line 852 of src/truetype/ttgload.c when it tries to access face->glyph_locations.".
Graham Asher 13217f25 2002-07-18T15:59:23 Added the incremental loading system for the TrueType driver. Tested using my own unit test code.
