| | | | | | | Check for Python and pip in the order p3, p2, p so that we use the same version of Python *and* pip at any given point of time. * builds/freetype.mk: Minor formatting.
* [builds] Add checks and targets for `docwriter'.Nikhil Ramakrishnan2018-08-013-32/+68
| | | | | | | | | | | | | | | | | | | | | | | | Add checks for Python, pip and docwriter. Docwriter is now a PyPI package, downloadable from https://pypi.org/project/docwriter/ This package can be installed with the command `pip install docwriter' on any system that has pip. Running `make' on a fresh build will now warn if package `docwriter' is not installed, and also provide information about the `make refdoc-venv' alternative. * builds/freetype.mk: Modify targats `refdoc' and `refdoc-venv' to use detected python version/alias, and run docwriter as a package. * builds/unix/configure.raw: Add rules to check python, pip and docwriter. (code discussed in the dev mailing list). * builds/unix/unix-def.in: Add variables PYTHON and PIP detected by `configure.ac'. This is conditionally assigned (if empty) in `freetype.mk' to the defaults.
* * builds/freetype.mk: Call python scripts with venv.Nikhil Ramakrishnan2018-07-292-7/+16
| | | | | | | | | Call Python scripts with the virtualenv directory created in `DOC_DIR/env'. Also ignore the folder in .gitignore. * builds/freetype.mk (refdoc-venv): Change all calls to local venv. * docs/reference/.gitignore: Add directory `env/'.
* * builds/freetype.mk: Add rule 'refdoc-venv'.Nikhil Ramakrishnan2018-07-288-1/+30
| | | | | | | | | | Add new rule `refdoc-venv' for building documentation in python virtualenv. This is an ongoing discussion at: http://lists.nongnu.org/archive/html/freetype-devel/2018-07/msg00209.html * builds/freetype.mk: Add rule `refdoc-venv' * builds/{os}/*-def.mk: Add variable `BIN' for virtualenv.

* [psaux, type1] Trace PostScript dictionaries and other things.Werner Lemberg2018-07-258-6/+182
| | | | | | | | | | | | | | | | | | | | | | | | | The tracing of /Encoding, /Subrs, and /Charstrings is rudimentary right now. * src/psaux/psobjs.c (ps_parser_load_field, ps_parser_load_field_table): Add tracing calls. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make tracing output more compact. * src/type1/t1gload.c (T1_Compute_Max_Advance, T1_Get_Advances): Add tracing messages. * src/type1/t1load.c (parse_blend_axis_types, parse_blend_design_positions, parse_blend_design_map, parse_weight_vector, t1_load_keyword, t1_parse_font_matrix, parse_encoding, parse_subrs, parse_charstrings, T1_Open_Face): Add tracing calls. * src/type1/t1objs.c (T1_Face_Init): Add tracing call. * src/sfnt/sfobjs.c (sfnt_init_face): Make tracing message more verbose.

* [build] Fortify dllexport/dllimport attributes (#53969,#54330).Alexei Podtelezhnikov2018-07-248-16/+35
| | | | | | | | | | | | | We no longer use predefined _DLL, which can be defined for static builds too with /MD. We use DLL_EXPORT and DLL_IMPORT instead, following libtool convention. * CMakeLists.txt [WIN32], builds/windows/vc2010/freetype.vcxproj: Define DLL_EXPORT manually. * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in, builds/vms/ftconfig.h, builds/windows/vc2010/index.html, src/base/ftver.rc: /_DLL/d, s/FT2_DLLIMPORT/DLL_IMPORT/.
* [type1] Check relationship between number of axes and designs.Werner Lemberg2018-07-242-9/+32
| | | | | | | | | | | | | | For Multiple Masters fonts We don't support intermediate designs; this implies that number_of_designs == 2 ^^ number_of_axes Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9557 * src/type1/t1load.c (T1_Open_Face): Ensure above constraint. (T1_Get_MM_Var): Remove now redundant test.
* [truetype] Match ttdebug's naming of instruction mnemonics.Hin-Tak Leung2018-07-242-67/+75
| | | | | | * src/truetype/ttinterp.c: The form used in ttdebug, "MDRP[G,B,W,?]", etc., is slightly more readable than "MDRP[00,01,02,03]".

* [pcf] Fix handling of the undefined glyph.Werner Lemberg2018-07-214-12/+94
| | | | | | | | | | | | | | | | | | | This change makes the driver use the `defaultChar' property of PCF files. * src/pcf/pcf.h (PCF_FaceRec): Change type of `defaultChar' to unsigned. * src/pcf/pcfread.c (pcf_get_encodings): Read `defaultChar' as unsigned. Validate `defaultChar'. If `defaultChar' doesn't point to glyph index zero, swap glyphs with index zero and index `defaultChar' and adjust the encodings accordingly. * src/pcf/pcfdrivr.c (pcf_cmap_char_index, pcf_cmap_char_next, PCF_Glyph_Load): Undo change from 2002-06-16 which always enforced the first character in the font to be the default character.

* [truetype] Increase precision while applying VF deltas.Werner Lemberg2018-06-242-63/+140
| | | | | | | | | | | | | | | | | | | | It turned out that we incorrectly round CVT and glyph point deltas before accumulation, leading to severe positioning errors if there are many delta values to sum up. Problem reported by Akiem Helmling <akiem@underware.nl> and analyzed by Behdad. * src/truetype/ttgxvar.c (ft_var_readpackeddelta): Return deltas in 16.16 format. (tt_face_var_cvt): Collect deltas in `cvt_deltas', which is a 16.16 format array, and add the accumulated values to the CVT at the end of the function. (TT_Vary_Apply_Glyph_Deltas): Store data in `points_org' and `points_out' in 16.16 format. Collect deltas in `point_deltas_x' and `point_deltas_y', which are 16.16 format arrays, and add the accumulated values to the glyph coordinates at the end of the function.
