Werner Lemberg 16586859 2020-06-13T21:15:45 Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

Ashish Azad 472119ac 2015-06-06T05:45:17 Fix Savannah bug #45260. * src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo.
Werner Lemberg a451638e 2015-03-11T08:09:13 Rename `svxf86nm.h' to `svfntfmt.h'; update related symbols. * include/internal/ftserv.h (FT_SERVICE_XFREE86_NAME_H): Renamed to... (FT_SERVICE_FONT_FORMAT_H): This. * include/internal/services/svfntfmt.h (FT_XF86_FORMAT_*): Renamed to ...

Werner Lemberg 8bfffb4c 2015-02-21T09:52:29 [pfr] Signedness fixes. * src/pfr/pfrdrivr.c, src/pfr/pfrgload.c, src/pfr/pfrload.c, src/pfr/pfrload.h, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c, src/pfr/pfrtypes.h: Apply.
Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
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.
Sean McBride 87628724 2014-03-18T08:39:35 Fix clang warnings. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Initialize some variables. * src/base/ftcalc.c (FT_MulFix): Only use code if `FT_MULFIX_INLINED' is not defined. * src/bdf/bdfdrivr.c (bdf_cmap_class), src/cache/ftcbasic.c (ftc_basic_image_family_class, ftc_basic_image_cache_class, ftc_basic_sbit_family_class, ftc_basic_sbit_cache_class), src/cache/ftccmap.c (ftc_cmap_cache_class), src/cache/ftcmanag.c (ftc_size_list_class, ftc_face_list_class), src/pcf/pcfdrivr.c (pcf_cmap_class), src/pfr/pfrdrivr.c (pfr_metrics_service_rec): Make function static. * src/type1/t1driver.c (t1_ps_get_font_value): Remove redundant code.
Werner Lemberg f6aa089f 2013-05-10T07:58:47 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code.
Werner Lemberg 89f50647 2013-03-14T17:50:49 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source 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 50997cd7 2008-07-16T21:03:40 * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error. * src/base/ftcalc.c (FT_MulFix): Fix portability issue. * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: Fix compiler warning.

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 b78c554d 2004-05-08T07:00:23 * src/pfr/pfrobjs.c, src/pfr/pfrobjs.h (pfr_face_init, pfr_face_done, pfr_face_get_kerning, pfr_slot_init, pfr_slot_done, pfr_slot_load): Don't use PFR_XXX but FT_XXX arguments which are typecast to the proper PFR_XXX types within the function. Update code accordingly. * src/pfr/pfrdrivr.c (pfr_get_kerning, pfr_get_advance, pfr_get_metrics, pfr_get_service): Don't use PFR_XXX but FT_XXX arguments which are typecast to the proper PFR_XXX types within the function. Update code accordingly. Use FT_CALLBACK_DEF throughout. (pfr_metrics_service_rec, pfr_driver_class): Remove casts.
Werner Lemberg b8bae640 2003-11-28T22:01:02 Fix ChangeLog. Formatting.
David Turner a77f713d 2003-11-27T21:01:24 * src/pfr/pfrdrivr.c (pfr_get_metrics): reverting to previous behaviour. Werner's "fix" was incorrect !!
Werner Lemberg 9f051a7f 2003-11-25T18:15:56 * src/base/ftcalc.c (FT_MulDiv_No_Round): New function (32 and 64 bit version). * include/freetype/internal/ftcalc.h: Updated. * src/truetype/ttinterp.c (TT_MULDIV_NO_ROUND): New macro. (TT_INT64): Removed. (DO_DIV): Use TT_MULDIV_NO_ROUND. * src/pfr/pfrdrivr.c (pfr_get_metrics): Directly use metrics->x_scale and metrics->y_scale.
Werner Lemberg be67c4ef 2003-11-24T22:54:58 * src/truetype/ttinterp.c (CUR_Func_move_orig): New macro. (Direct_Move_Orig, Direct_Move_Orig_X, Direct_Move_Orig_Y): New functions. Similar to Direct_Move, Direct_Move_X, and Direct_Move_Y but without touching. (Compute_Funcs): Use new functions. (Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45): Fix rounding of value zero. (DO_DIV): Don't use TT_MULDIV. (Ins_SHC): This instruction actually touches the points. (Ins_MSIRP): Fix undocumented behaviour. * src/truetype/ttinterp.h (TT_ExecContextRec): Updated. * docs/VERSION.DLL: Updated. * src/base/ftobjs.c (FT_Set_Char_Size): Make metrics->x_scale and metrics->y_scale really precise. (FT_Load_Glyph): Update computation of linearHoriAdvance and linearVertAdvance. * src/true/type/ttinterp.c (Update_Max): Use FT_REALLOC.

David Turner e2d12842 2003-09-21T17:15:55 * include/freetype/internal/fnttypes.h, include/freetype/internal/ftserv.h, src/base/ftbdf.c, src/base/ftmm.c, src/base/ftobjs.c, src/base/ftpfr.c, src/base/ftwinfnt.c, src/base/ftxf86.c, src/pfr/pfrdrivr.c, src/winfonts/winfnt.c, src/winfonts/winfnt.h, include/freetype/internal/service/svwinfnt.h,: simplification of service lookup macros, updating the PFR and WINFNT font drivers to new services
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'.
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 052904e3 2003-06-17T10:42:27 * include/freetype/ftglyph.h (ft_glyph_bbox_unscaled, ft_glyph_bbox_subpixels, ft_glyph_bbox_gridfit, ft_glyph_bbox_truncate, ft_glyph_bbox_pixels): Replaced with FT_GLYPH_BBOX_UNSCALED, FT_GLYPH_BBOX_SUBPIXELS, FT_GLYPH_BBIX_GRIDFIT, FT_GLYPH_BBOX_TRUNCATE, FT_GLYPH_BBOX_PIXELS. The lowercase variants are now (deprecated aliases) to the uppercase versions. Updated all other files. * include/freetype/ftmodule.h (ft_module_font_driver, ft_module_renderer, ft_module_hinter, ft_module_styler, ft_module_driver_scalable, ft_module_driver_no_outlines, ft_module_driver_has_hinter): Replaced with FT_MODULE_FONT_DRIVER, FT_MODULE_RENDERER, FT_MODULE_HINTER, FT_MODULE_STYLER, FT_MODULE_DRIVER_SCALABLE, FT_MODULE_DRIVER_NO_OUTLINES, FT_MODULE_DRIVER_HAS_HINTER. The lowercase variants are now (deprecated aliases) to the uppercase versions. Updated all other files. * src/base/ftglyph.c (FT_Glyph_Get_CBox): Handle bbox_mode better as enumeration. * src/pcf/pcfdrivr.c (pcf_driver_class), src/winfonts/winfnt.c (winfnt_driver_class), src/bdf/bdfdrivr.c (bdf_driver_class): Add the FT_MODULE_DRIVER_NO_OUTLINES flag.
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'. (_bdf_parse_glyphs): Remove unused variable `next'. Mark `call_data' as unused. * src/cache/ftlru.c (FT_LruList_Lookup): Remove unused variable `plast'. * src/pcf/pcfread.c (pcf_seek_to_table_type): Slight recoding to actually use `error'. (pcf_load_font): Remove unused variable `avgw'. * src/pfr/pfrobjs.c (pfr_face_get_kerning): Change return type to `void'. Mark `error' as unused. * src/pfr/pfrobjs.h: Updated. * src/pfr/pfrdrivr.c (pfr_get_kerning): Updated. * src/sfnt/ttload.c (sfnt_dir_check): Remove unused variable `format_tag'. * src/sfnt/ttcmap0.c (tt_cmap6_validate, tt_cmap10_validate): Remove unused variable `start'. (tt_cmap10_char_next): Remove unused variable `result' * src/sfnt/sfobjs.c (tt_face_get_name): Mark `error' as unused. * src/sfnt/sfdriver.c (get_sfnt_postscript_name): Mark `error' as unused. * src/type1/t1objs.c (T1_Face_Init): Remove unused variable `pshinter'. * src/type1/t1gload.c (T1_Load_Glyph): Use `glyph_data_loaded' only for FT_CONFIG_OPTION_INCREMENTAL.
Werner Lemberg 2e57343f 2003-04-23T14:14:06 * src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist instead of FT_Uint for `len'. Cleanups.
David Turner 60b32e16 2002-11-06T22:32:54 2002-11-05 David Turner <david@freetype.org> * include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify the use of system-wide zlib. Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore. This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings in optimized mode relative to the "volatile" local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same than a volatile pointer to a variable :-) the fix was to change "volatile FT_Byte* p" into "FT_Byte* volatile p" * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed compiler warnings in optimized modes * src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting any zlib function names outside of the component. This prevents linking problems on some platforms, when applications want to link FreeType _and_ ZLib together. 2002-11-05 Juliusz <jch@pps.jussieu.fr> * src/psaux/psobjs.c (ps_table_add): modified increment loop in order to implement exponential behaviour
David Turner 3249c625 2002-10-31T08:30:19 * include/freetype/internal/internal.h, include/freetype/ftpfr.h, src/base/ftpfr.c, src/base/Jamfile, src/descrip.mms, src/rules.mk, src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h: added PFR-specific public API. Fixed the kerning retrievel routine (it returned invalid values when the outline and metrics resolution differ) * src/base/ftsynth.c: fixed the synthetic emboldener. at last. * src/base/ftobjs.c: small internal fix to better support bitmap-based font formats
David Turner 3e19d85d 2002-07-17T21:52:20 * include/freetype/config/ftoption.h, include/freetype/internal/tttypes.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/pcf/pcfdrivr.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h, src/sfnt/ttload.c, src/type1/t1objs.c, src/type42/t42objs.c, src/winfonts/winfnt.c: code cleanup, FT_CONFIG_OPTION_USE_CMAPS is now the default

(pfr_phy_font_load): s/size/Size/ for local variable to avoid compiler warning. * src/pfr/pfrobjs.c (pfr_face_init): Fix debug message. (pfr_slot_load): Remove redundant local variable. adding copyrights, formatting
David Turner 609e28c3 2002-04-19T15:13:47 * src/type1/t1gload.h, src/type1/t1gload.c: fixed incorrect parameter sign-ness in callback function * include/freetype/config/ftmodule.h, include/freetype/internal/fttrace.h, src/Jamfile, src/pfr/*: adding a PFR font driver to the FreeType sources. Not that it doesn't support embedded bitmaps or kerning tables for now.. * include/freetype/internal/ftmemory.h: adding the FT_MEM_ZERO and FT_ZERO macros * include/freetype/internal/ftstream.h: adding the FT_NEXT_OFF3, FT_NEXT_UOFF3, FT_NEXT_OFF3_LE and FT_NEXT_UOFF3_LE to parse in-memory 24-bit integers.
