The font variation code. All parts dependent on the GX code in the `truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. In other words, you can still compile the `cff' module without defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2 support without font variation). * src/cff/cf2font.c (cf2_font_setup): Add support for font variation. * src/cff/cf2font.h (CF2_Font): Add fields for variation data. * src/cff/cf2ft.c (cf2_free_instance): Free blend data. (cf2_getVStore, cf2_getNormalizedVector): New functions. * src/cff/cf2ft.h: Updated. * src/cff/cf2intrp.c: Include `cffload.h'. (cf2_cmdRESERVED_15, cf2_cmdRESERVED_16): Replace with... (cf2_cmdVSINDEX, cf2_cmdBLEND): ... this new enum values. (cf2_doBlend): New function. (cf2_interpT2CharString): Handle `vsindex' and `blend' opcodes. * src/cff/cffload.c (FT_fdot14ToFixed): New macro. (cff_vstore_done, cff_vstore_load): New functions. (cff_blend_clear, cff_blend_doBlend, cff_blend_build_vector, cff_blend_check_vector): New functions. (cff_load_private_dict): Add arguments for blend vector. Handle blend data. (cff_subfont_load, cff_subfont_done): Updated. (cff_font_load): Handle CFF2 variation store data. (cff_font_done): Updated. * src/cff/cffload.h: Include `cffparse.h'. Updated. * src/cff/cffobjs.c (cff_face_done): Updated. * src/cff/cffparse.c: Include `cffload.h'. (cff_parse_num): Handle internal value 255. (cff_parse_vsindex, cff_parse_blend): New functions. (CFF_FIELD_BLEND): New macro. (cff_parser_run): Updated. * src/cff/cffparse.h (cff_kind_blend): New enum value. * src/cff/cfftoken.h: Handle `vstore', `vsindex', and `blend' dictionary values. * src/cff/cfftypes.h (CFF_VarData, CFF_AxisCoords, CFF_VarRegion, CFF_VStore, CFF_Blend): New structures. (CFF_FontRecDict): Add `vstore_offset' field. (CFF_Private): Add `vsindex' field. (CFF_SubFont): Add fields for blend data. (CFF_Font): Add `vstore' field. * src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar', since glyph variation data is directly embedded. (TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts. |

README
FreeType 2.7
============
Homepage: http://www.freetype.org
FreeType is a freely available software library to render fonts.
It is written in C, designed to be small, efficient, highly
customizable, and portable while capable of producing high-quality
output (glyph images) of most vector and bitmap font formats.
Please read the docs/CHANGES file, it contains IMPORTANT
INFORMATION.
Read the files `docs/INSTALL*' for installation instructions; see
the file `docs/LICENSE.TXT' for the available licenses.
The FreeType 2 API reference is located in `docs/reference'; use the
file `ft2-toc.html' as the top entry point. Additional
documentation is available as a separate package from our sites. Go
to
http://download.savannah.gnu.org/releases/freetype/
and download one of the following files.
freetype-doc-2.7.tar.bz2
freetype-doc-2.7.tar.gz
ftdoc27.zip

e-mail lists.
general use and discussion: freetype@nongnu.org

Bugs
====
Please submit bug reports at
https://savannah.nongnu.org/bugs/?group=freetype
Alternatively, you might report bugs by e-mail to
`freetype-devel@nongnu.org'. Don't forget to send a detailed
explanation of the problem -- there is nothing worse than receiving
a terse message that only says `it doesn't work'.
Enjoy!
