README
skrifa
This crate aims to be a robust, ergonomic, high performance library for reading OpenType fonts. It is built on top of the read-fonts low level parsing library and is also part of the oxidize project.
Features
Metadata
The following information is currently exposed:
- Global font metrics with variation support (units per em, ascender, descender, etc)
- Glyph metrics with variation support (advance width, left side-bearing, etc)
- Codepoint to nominal glyph identifier mapping
- Unicode variation sequences
- Localized strings
- Attributes (stretch, style and weight)
- Variation axes and named instances
- Conversion from user coordinates to normalized design coordinates
Future goals include:
- Color palettes
- Embedded bitmap strikes

Panicking
This library should not panic regardless of API misuse or use of corrupted/malicious font files. Please file an issue if this occurs.
The name?
Following along with our theme, skrifa is Old Norse for "write" or "it is written." And so it is named.
Safety
Unsafe code is forbidden by a #![forbid(unsafe_code)] attribute in the root
of the library.
