Werner Lemberg 10e2bb8b 2015-03-29T13:32:47 [type1, truetype] Make the MM API more flexible w.r.t. `num_coords'. This commit allows `num_coords' to be larger or smaller than the number of available axes while selecting a design instance, either ignoring excess data or using defaults if data is missing. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Implement it. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design, T1_Set_Var_Design): Ditto.

Werner Lemberg 3b5f332c 2015-02-18T11:45:22 [type1] Fix signedness issues. * include/internal/psaux.h, include/internal/t1types.h, src/psaux/psobjs.c, src/psaux/psobjs.h, src/psaux/t1decode.c, src/type1/t1gload.c, src/type1/t1load.c, src/type1/t1parse.c: Apply.

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 8b281f83 2014-01-23T08:14:53 Fix Savannah bug #41309. * src/type1/t1load.c (t1_parse_font_matrix): Properly handle result of `T1_ToFixedArray'. * src/cid/cidload.c (cid_parse_font_matrix): Synchronize with `t1_parse_font_matrix'. * src/type42/t42parse.c (t42_parse_font_matrix): Synchronize with `t1_parse_font_matrix'. (t42_parse_encoding): Synchronize with `t1_parse_encoding'. * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_BBOX>, <T1_FIELD_TYPE_MMOX>: Properly handle result of `ps_tofixedarray'.
Werner Lemberg e8ed2d62 2013-08-01T12:20:20 Another round of cppcheck nitpicks. The call was (from the top-level of the FreeType tree): cppcheck --force \ --enable=all \ -I /usr/include \ -I /usr/local/include \ -I /usr/lib/gcc/i586-suse-linux/4.7/include \ -I include \ -I include/freetype \ -I include/freetype/config \ -I include/freetype/internal \ -DFT2_BUILD_LIBRARY \ . &> cppcheck.log using cppcheck git commit f7e93f99. Note that cppcheck still can't handle `#include FOO' (with `FOO' a macro). */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/gxvalid/*: Comment out redundant code or guard it with FT_DEBUG_LEVEL_TRACE.
Werner Lemberg c06889eb 2013-06-12T10:58:06 More compiler warning fixes. */*: Use cast to `FT_Bool' (or `Bool') where appropriate.
Werner Lemberg 45392b77 2013-06-05T13:43:20 Fix compiler warnings. * include/freetype/internal/ftmemory.h: Decorate memory allocation macros with `FT_Long' where appropriate. Remove duplicate of FT_MEM_QRENEW_ARRAY definition. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Use cast. * src/base/ftobjs.c: Add warning disabling pragma for MSVC while including `md5.c'. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdESC>: Add cast. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_compound): Fix casts. (tt_sbit_decoder_load_bitmap): Beautification. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Initialize variables (earlier). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Pacify compiler. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Use unsigned constants where appropriate. * src/type1/t1load.c (T1_Get_MM_Var): Ditto.
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 d6bc524b 2013-03-11T09:50:53 Always use module related error codes. * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use `FT_ERROR_BASE'. * src/type1/t1load.c (parse_encoding): Use T1_Err_Unknown_File_Format.

Werner Lemberg a9f6f85e 2012-12-17T09:08:09 Various compiler warning fixes. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use `logical not' operator instead of negation. The idea is that `~' returns exactly the data type enforced by the cast to a pointer (be it 32bit or 64bit or whatever), while a negative integer has not this flexibility. * src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto. * src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto. * src/type/t1load.c (T1_Get_MM_Var): Ditto. (parse_blend_axis_types): Use cast. * src/bdf/bdflib.c (_bdf_readstream): Use cast.

John Tytgat 03e8b2f7 2009-09-01T08:10:24 Fix custom cmap for empty Type 1 font (Savannah bug #27294). * include/freetype/internal/t1types.h (T1_EncodingRecRec_): Update comment to reflect revised code_last meaning. * src/type1/t1load.c (T1_Open_Face), src/type42/t42objs.c (T42_Open_Face): Assign max_char as highest character code + 1 and use this for T1_EncodingRecRec_::code_last. * src/psaux/t1cmap.c (t1_cmap_custom_init): Follow revised T1_EncodingRecRec_::code_last meaning.
Werner Lemberg 858abbed 2009-06-26T06:15:41 For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings.
Werner Lemberg 11cb8c36 2009-06-22T16:56:47 Use 16.16 format while parsing Type 1 charstrings. This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H. (t1_build_add_point): Always convert fixed to integer. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Use 16.16 format everywhere (except for large integers followed by a `div'). [CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate code uncoditionally. Add support for random numbers and update remaining code accordingly; this should work now.

David Turner 01ca4da2 2009-03-03T13:28:59 Remove ABI-breaking field in public PS_InfoFontRec definition. Instead, we define a new internal PS_FontExtraRec structure to hold the additionnal field, then place it in various internal positions of the corresponding FT_Face derived objects.

Werner Lemberg c011f4cb 2006-06-26T09:40:00 The Type 1 parser now skips over top-level procedures as required for a `Simplified Parser'.
