Font introspection, complex text shaping and glyph rendering.
For a comprehensive list of features provided by this crate, please check out the readme on GitHub.
This is a low level library focusing on implementations of OpenType and various related Unicode specifications for building high quality, high performance text layout and rendering components with minimal overhead.
If you’re looking for something higher level, please stay tuned– work is in progress.
The primary currency in this crate is the
FontRef struct so you’ll want to
start there to learn how to construct and use fonts.
