woff2 is a crate for converting WOFF2 font files to OpenType fonts.
use woff2::decode::{convert_woff2_to_ttf, is_woff2};
let buffer = std::fs::read("src/test_resources/lato-v22-latin-regular.woff2").unwrap();
assert!(is_woff2(&buffer));
let ttf = convert_woff2_to_ttf(&mut std::io::Cursor::new(buffer)).unwrap();
// ... use `ttf` however you would use a loaded TTF fileThe decoder example is a simple command-line application to convert a WOFF2
font to OpenType format:
cargo run --example decoder input-filename.woff2 output-filename.ttf- WOFF2 fonts with
hmtxtransformations are not yet supported. It seems like these transformations are rare and we haven't found one yet. You can help by submitting a sample font that has them. - WOFF (the original WOFF format) is not supported
- Converting OpenType to WOFF2 is not supported yet.
- WOFF File Format 2.0
- Reference code
- Allsorts We used some of the
glyfdecoding logic from Allsorts.
