Glifo

Glifo provides APIs for efficiently rendering glyphs and paint styles like underline.

Goals

Glifo is under rapid development. Consider it experimental for now. Its goals are to:

• Provide an API surface that accepts glyphs and their positions and renders them to a surface.
• Cache those glyphs so that repeated renders of a glyph are fast.
• Support rendering paint styles like underline, strikethrough, and brush color.
• Share expensive structs and data between the shaper and renderer like the hinting instance and hinted advance.

Minimum supported Rust Version (MSRV)

This version of Glifo has been verified to compile with Rust 1.88 and later.

Future versions of Glifo might increase the Rust version requirement. It will not be treated as a breaking change and as such can even happen with small patch releases.
