Font -- Pure Rust font parsers

Supported Formats

TrueType

• kern Table supported
• Full outline support
• Most CMAPs implemented
• all glyphs listed in any cmap can be accessed with gid_for_unicode_codepoint (or gid_for_codepoint which calls the former)

CFF (Compact Font Format)

• Charstring format 1 and 2 are fully implemented
• All glyphs that are listed by /Encoding can be accessed via gid_for_codepoint. Glyphs can be looked up from unicode values if they are defined in Adobes StandardEncoding.
• All glyphs can be accessed by name using gid_for_name
• (not yet implemented: Translating codepoints into glyph names and using them for lookup)

Type1

• Contains a PostScript interpreter (without file access)
• Calling PostScript from CharStrings (used for Hinting) is not implemented. Instead they are emulated and the correct outline is produced.
• Glyphs can accessed with:
  • gid_for_name using the name of the charstring
  • gid_for_codepoint using the built in /Encoding
  • gid_for_unicode_codepoint using the AFL-Glyphlist

OpenType

• The glyf (TrueType) and CFF (Type1) outlines are supported.
• SVG outlines are supported.
• Most of the CMAP formats are implemented.
• Kerning using the kern and GPOS table is implemented.

WOFF / WOFF2

• essentially OpenType fonts. implemented and working.

API

NOTE: The code may change a bit. Especially multi-codepoint glyphs cannot be looked up yet. Fonts are loaded with parse, which returns a trait object.
