David Turner dd0f3609 2006-02-20T23:50:21 * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit.c: moving the definition of 'set_sbit_strike' and 'load_sbit_metrics' to their 2.1.8 location. This is used to support binary compatibility with the X.Org server's libXfont library. note that this disables memory optimizations for the embedded bitmap loader.Sigh....
Werner Lemberg 8e6f8c4d 2006-02-17T08:07:09 Formatting, copyright years, documentation improvements.
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.
Werner Lemberg 5225402a 2006-02-15T06:05:52 * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in documentation that negative strength values are possible. Give an example call. * include/freetype/freetype.h (FT_GlyphSlotRec): Improve documentation of `outline' field. * src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H. * src/sfnt/sfdriver.c: Include ttmtx.h. * src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
Wu, Chia-I (吳佳一) 35222ff7 2006-02-14T07:25:57 Clean up the SFNT_Interface. In this final pass, `load_hmtx' is splitted from `load_hhea'. * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c, src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'. * src/sfnt/sfobjs.c (sfnt_load_face): Update.
Wu, Chia-I (吳佳一) 65863a57 2006-02-14T07:01:29 Clean up the SFNT_Interface. In this pass, we want to treat the font directory (offset table and table directory) as a normal table like the others. This also means that TTC is no longer recognized there, but in `init_face'. * include/freetype/internal/sfnt.h (SFNT_Interface), src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are combined and renamed to `load_font_dir'. * src/sfnt/ttload.h, src/sfnt/ttload.c: s/sfnt_dir_check/check_table_dir/. `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'. `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined and renamed to `tt_face_load_font_dir'. * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
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. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.
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.
Werner Lemberg b79b5133 2005-12-20T12:01:58 Formatting, improving comments.
David Turner 89a2a4b5 2005-12-14T20:38:15 * include/freetype/config/ftoption.h, include/freetype/config/ftstdlib.h, include/freetype/internal/tttypes.h, src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c: Added support for an embedded 'BDF ' table within SFNT-based bitmap font files. This is used to store atoms & properties from the original BDF fonts that were used to generate the font file. the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h' and is used to implement FT_Get_BDF_Property for these font files. At the moment, this is still experimental, the BDF table format isn't cast into stone yet.
Werner Lemberg 43b057b6 2005-10-26T18:37:40 * src/sfnt/sfdriver.c (sfnt_interface): Move out `tt_face_get_kerning' from a #ifdef clause. Reported by Tony J. Ibbs <tibs@sj.co.uk>.

Werner Lemberg b2d65d75 2005-08-03T21:21:11 * src/sfnt/sfdriver.c (sfnt_interface) [FT_OPTIMIZE_MEMORY]: Reactivate pointers to tt_find_sbit_image and tt_load_sbit_metrics to make X work again.
Werner Lemberg f13516c8 2005-03-03T17:09:08 Various fixes for C and C++ compiling. * src/autofit/*: Add copyright messages. Formatting. * src/autofit/afhints.c (af_glyph_hints_done): Don't use `AF_Dimension' but `int' for loop counter. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Don't use `AF_Dimension' but `int' for loop counter. Use proper enumeration value for `render_mode'. (af_latin_metrics_scale_dim): Don't shadow variables. (af_latin_hints_compute_segments): Use proper cast for `major_dir' and `segment_dir'.

Werner Lemberg e793092d 2005-03-01T02:13:50 Formatting. * src/truetype/ttpload.c (tt_face_load_loca): Fix typo. * src/sfnt/ttkern.c: Include `ttkern.h'. (FT_COMPONENT): Updated. * include/freetype/internal/fttrace.h: Add entry for `ttkern'. * src/sfnt/ttsbit0.c: s/FT_Err_/SFNT_Err_/. Decorate constants with `U' and `L' where necessary. * src/sfnt/ttcmap.c (tt_cmap4_next): Remove unused variable.
David Turner 6a487b59 2005-02-28T22:09:07 * src/base/ftdbgmem.c (FT_DumpMemory): added sorting of memory sources according to decreasing maximum cumulative allocations. * include/freetype/internal/tttypes.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/truetype/ttobjs.c, src/cff/cffobjs.c, src/sfnt/sfobjs.c: implementing new heap-optimized embedded bitmap loader. This one also fixes bug #12107 * src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without a 'kern' table.
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 4b8397c7 2004-08-29T16:50:09 * src/otlayout/otlgpos.c (otl_gpos_subtable_validate): Add argument to pass number of lookups. Update all callers. Don't call otl_lookup_list_validate but otl_lookup_validate. (otl_gpos_validate): Call otl_lookup_list_validate instead of otl_gpos_subtable_validate. * src/otlayout/otlgpos.h: Updated. * src/otlayout/otljstf.c (otl_jstf_max_validate): Add argument to pass number of lookups. Update all callers. * src/cff/cffparse.c (cff_parse_real): s/exp/exponent/ to avoid compiler warning. * src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h: Renamed to... * src/sfnt/ttcmap.c, src/sfnt/ttcmap.h: This. * src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c: Updated. * builds/compiler/gcc-dev.mk (CFLAGS): Don't add `-Wnested-externs' if compiler is g++ (v3.3.3 emits a warning otherwise).
Werner Lemberg 17439423 2004-08-11T05:25:37 * src/base/ftstream.c (FT_Stream_Close): Don't reset stream->close to NULL. This allows custom close functions to delete the FT_STREAM object. Add API to get information about SFNT tables. * include/freetype/internal/services/svsfnt.h (FT_SFNT_Table_Info_Func): New typedef. (SFNT_Table): Add it. * src/base/ftobjs (FT_Sfnt_Table_Info): New function. * include/freetype/tttables.h: Updated. * src/sfnt/sfdriver.c (sfnt_table_info): New function.

Werner Lemberg deadbb53 2004-04-13T21:08:17 * include/freetype/config/ftconfig.h: Use CHAR_BIT to define size of FT_SIZEOF_xxx. * include/freetype/internal/sfnt.h (TT_Find_SBit_Image_Func, TT_Load_SBit_Metrics_Func): New typedefs. (SFNT_Interface): Add find_sbit_image and load_sbit_metrics. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/sfnt/ttsbit.h (tt_find_sbit_image, tt_load_sbit_metrics): New declarations. * src/sfnt/ttsbit.c (find_sbit_image): Renamed to... (tt_find_sbit_image): This. Updated all callers. (load_sbit_metrics): Renamed to... (tt_load_sbit_metrics): This. Updated all callers.
Werner Lemberg 91a67478 2003-12-17T14:28:22 Add new function FT_Get_CMap_Language_ID to extract the language ID for TrueType/sfnt fonts. * include/freetype/internal/services/svttcmap.h: New file. * include/freetype/internal/ftserv.h (FT_SERVICE_TT_CMAP_H): Add svttcmap.h. * src/sfnt/sfdriver.c: Include ttcmap0.h.

Werner Lemberg b066c153 2003-12-16T06:42:11 * src/sfnt/ttcmap.c, src/sfnt/ttcmap.h: Removed. Obsolete. * include/freetype/internal/sfnt.h (SFNT_Interface): Remove obsolete fields `load_charmap' and `free_charmap'. (TT_CharMap_Load_Func, TT_CharMap_Free_Func): Removed. * src/sfnt/sfnt.c: Don't include ttcmap.c. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttcmap.c. * src/sfnt/ttload.c: Don't include ttcmap.h. * src/sfnt/sfdriver.c: Don't include ttcmap.h. (sfnt_interface): Updated.
Werner Lemberg 82906bfb 2003-11-04T18:24:20 * src/sfnt/sfdriver.c: Include FT_SERVICE_SFNT_H. (sfnt_service_sfnt_table): New service. (sfnt_services): Updated. * docs/license.txt: Reworded.
Werner Lemberg 40bb0964 2003-11-01T14:36:20 * src/base/fttype1.c (FT_Get_PS_Font_Info, FT_Has_PS_Glyph_Names): Fix parameter order in calls to FT_FACE_FIND_SERVICE. * include/freetype/internal/ftserv.h (FT_SERVICE_POSTSCRIPT_NAMES_H): Removed. Unused. * src/type42/t42drivr.c (t42_services): Updated.
Werner Lemberg 1c0b8e9d 2003-10-23T04:54:14 Only whitespace changes.
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 013efd14 2003-09-17T05:26:33 Formatting.
Werner Lemberg 754d5588 2003-09-12T20:32:51 * src/cff/cffcmap.c: Include `cfferrs.h'. * src/pfr/pfrdrivr.c: Include `pfrerror.h'. * src/sfnt/sfdriver.c: Include `sferrors.h'. * src/psaux/psobjs.h: Add declaration for `ps_parser_to_bytes'.
David Turner c313c502 2003-09-11T19:51:54 * include/freetype/ftmm.h, include/freetype/ftmodule.h, include/freetype/tttables.h, include/freetype/config/ftconfig.h, include/freetype/internal/ftobjs.h, include/freetype/internal/ftserv.h, include/freetype/internal/internal.h, include/freetype/internal/sfnt.h, include/freetype/internal/tttypes.h, include/freetype/internal/services/bdf.h, include/freetype/internal/services/glyfdict.h, include/freetype/internal/services/multmast.h, include/freetype/internal/services/postname.h, include/freetype/internal/services/sfnt.h, include/freetype/internal/services/xf86name.h, src/base/ftbdf.c, src/base/ftmm.c, src/base/ftobjs.c, src/base/ftxf86.c, src/bdf/bdfdrivr.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type42/t42drivr.c: heavy internal modifications to introduce the concept of "module services". This is the first step towards a massive simplification of the engine's internals, in order to get rid of various numbers of hacks. Note that this changes will break source & binary compatibility for authors of external font drivers. Maybe 2.1.6 will be called 2.2.0 after all :-)
Werner Lemberg 779afe4b 2003-06-22T15:33:53 * src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in computation of glyph_index. (FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Size): Assign value to `metrics' after validation of arguments. Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes. The `max_advance' field of the FT_Size_Metrics structure should be used to get the (maximum) width of a strike. * src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single argument to function. * src/psnames/psmodule.c (ps_unicode_value): Handle `.' after `uniXXXX' and `uXXXX[X[X]]'. * src/bdf/bdfdrivr.c: s/FT_Err_/BDF_Err/. * src/cache/ftccache.c, src/cache/ftcsbits.c, src/cache/ftlru.c: s/FT_Err_/FTC_Err_/. * src/cff/cffcmap.c: s/FT_Err_/CFF_Err_/. * src/pcf/pcfdrivr.c: s/FT_Err_/PCF_Err_/. * src/psaux/t1cmap.c: Include psauxerr.h. s/FT_Err_/PSaux_Err_/. * src/pshinter/pshnterr.h: New file. * src/pshinter/rules.mk: Updated. * src/pshinter/pshalgo.c, src/pshinter/pshrec.c: Include pshnterr.h. s/FT_Err_/PSH_Err_/. * src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c: s/FT_Err_/PFR_Err_/. * src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c: s/FT_Err_/SFNT_Err_/. * src/truetype/ttgload.c: s/FT_Err_/TT_Err_/. * src/gzip/ftgzip.c: Load FT_MODULE_ERRORS_H and define FT_ERR_PREFIX and FT_ERR_BASE. s/FT_Err_/Gzip_Err_/.
Werner Lemberg 319c00d7 2003-04-23T19:48:24 Fixing bugs reported by Nelson Beebe. * src/base/ftstroker.c (FT_Stroker_ParseOutline): Remove unused variable `in_path'. * src/base/ftobjs (ft_glyphslot_set_bitmap): Change type of second argument to `FT_Byte*'. * include/freetype/internal/ftobjs.h: Updated. * src/bdf/bdflib.c (_bdf_readstream): Remove unused variable `res'.

David Turner 621e4886 2002-12-16T21:51:24 2002-12-16 David Turner <david@freetype.org> * docs/VERSION.DLL: updating document to better explain the differences between the three version numbers being used on Unix, as well as provide the AutoConf fragment provided by Lars Clausen * src/smooth/ftgrays.c (gray_render_conic): fixed small bug that prevented bezier arcs with negative vertical coordinates to be rendered appropriately 2002-11-27 Vincent Caron <v.caron@zerodeux.net> * builds/unix/unix-def.in, builds/unix/freetype-config.in, builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c: adding support for system zlib installations when available on the target platform (Unix only)
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_.
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.
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 5f0ee94c 2002-04-30T06:37:52 `interface' is reserved on the Mac. * include/freetype/ftoutln.h, include/freetype/internal/sfnt.h, src/base/ftoutln.c: s/interface/func_interface/. * src/base/ftbbox.c (FT_Outline_Get_BBox): s/interface/bbox_interface/. * src/cff/cffdrivr.c: s/interface/module_interface/. * src/cff/cffload.c, src/cff/cffload.h: s/interface/psnames_interface/. * src/cid/cidriver.c: s/interface/cid_interface/. * src/sfnt/sfdriver.c: s/interface/module_interface/. * src/smooth/ftgrays.c: s/interface/func_interface/. * src/truetype/ttdriver.c: s/interface/tt_interface/. * src/type1/t1driver.c: s/interface/t1_interface/.
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.
Werner Lemberg 2282f341 2002-03-28T14:21:15 * src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fix serious typos.
David Turner 94dbf7f0 2002-03-26T02:38:39 fixed a small bug in FT_CMaps support
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 678e0d46 2002-03-20T10:47:38 * src/sfnt/sfdriver.c (get_sfnt_postscript_name): fixed memory leak
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.
Werner Lemberg b5349a9b 2002-02-19T16:30:15 * builds/freetype.mk (FT_CFLAGS): Use $(INCLUDE_FLAGS) first. * src/cache/ftccache.c (ftc_cache_resize): Mark `error' as unused to avoid compiler warning. * src/cff/cffload.c (CFF_Get_String): Ditto. * src/cff/cffobjs.c (CFF_StrCopy): Ditto. * src/psaux/psobjs.c (PS_Table_Done): Ditto. * src/pcf/pcfread.c (pcf_seek_to_table_type): Ditto. * src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.

Werner Lemberg 52005c30 2001-06-27T23:25:46 formatting
David Turner dee78134 2001-06-27T09:26:46 * include/freetype/ftconfig.h, src/*/*.c: changed the definition and uses of the FT_CALLBACK_DEF macro in order to support 16-bit compilers
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..
Werner Lemberg 914b289f 2001-03-10T17:07:42 * src/*/*.c: Added many casts to make code more 64bit-safe.
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
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).
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 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 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!
Werner Lemberg d060a75b 2000-07-20T06:57:41 Formatting. Rudimentary support for autoconf (still using GNU make) Say `make unix'.
David Turner 6930b45f 2000-07-19T17:13:03 - introduced FT_Get_Glyph_Name (see freetype.h) to access individual glyph names. Changed some drivers to support it through a new interface named "glyph_name". - introduced FT_Get_Sfnt_Name (see ftnames.h) to access the SFNT name table in a TrueType/OpenType file..
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 fbeb41d9 2000-07-02T00:27:53 Formatting. Adding copyright notices. Removing an unnecessary file (smooth.h).
Werner Lemberg a8bbc267 2000-07-01T14:06:46 Formatting as usual... Adding trivial argument checking to some functions. Added dynamic driver interface to cidriver. Minor `version' fixes for macfont and psnames modules. Removed unnecessary files
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 4e6dd858 2000-06-05T05:26:15 freetype.h: Adding ft_encoding_xxx values for some CJK encodings. Fixing copyright notice on many files. Changed some tracing levels. A lot of formatting, fixing documentation etc. as usual.
David Turner b1677a87 2000-05-29T20:37:41 changed the SFNT driver slightly to add more robust checking based on the "search_rang", etc.., fields of the sfnt header.. This avoids problems (like certain Type 1 multiple masters incorrectly recognized as trueType files)..
David Turner 2e421319 2000-05-26T22:13:17 moved a lot of things from the TrueType driver to the SFNT module (whose interface has changed, by the way) This allows even more code re-use between TrueType and OpenType formats..
David Turner 11187206 2000-05-26T17:13:23 finalised the multiple masters support fixed some nasty little bugs too
David Turner 51179f0a 2000-05-18T16:18:05 some fixes for 64-bit systems. Mainly changed some FT_TRACE calls to use %p instead of %lx when dumping a pointer address
David Turner e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
David Turner c30aea98 2000-05-12T15:01:18 another massive changes in order to completely avoid compiler warnings with GCC + "-ansi -pedantic -Wall -W" and LCC. Also fixed the compilation of "type1z" with Win32-LCC (its pre-processor is broken !!) Updated the BUILD document too
David Turner bfe2f98f 2000-05-12T12:17:15 a new massive grunt work. Redefined the EXPORT_DEF, EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to let them take an argument.. This is needed to compile the library as a DLL on some platforms that have different compiler conventions..
David Turner efce08d6 2000-05-11T18:23:52 major re-organisation of the FreeType 2 directory hierarchy
David Turner 7f7aadf4 2000-03-13T12:57:27 finished moving all configuration macros to "config/ftoption.h"
David Turner d42c68e8 2000-01-27T13:56:02 many new small, but important, changes there: - modified the interface of the "sfnt" module. There is now a function called "load_format_tag", and another called "load_directory". The first one is in charge of returning the 4-byte tag located at the beginning of a given font file. It understand TrueType collections and parses them automatically The second loads the table directory that is located just after the format tag. This is useful, because the "SFNT" storage scheme can be used by several distinct formats, each with its own format tag. The TrueType driver now checks the format tag in "src/truetype/ttobjs.c" - made some changes to "src/shared/t1types.h" to clearly separate the Type 1 font content from the rest of the T1_Face structure. This will be useful when adding the CFF/Type2 driver that will be able to reuse the "T1_Font" structure within a "TT_Font" one (which really describes a SFNT-based font file). Some changes in "src/type1" were thus performed to reflect this. Note that the current type1 driver will be discontinued in a distant future. More on this later..
