When you want to render text, fonterator gives you an iterator over
footile PathOps, which you can easily
pass right into footile.
- Loads TTF/OTF fonts and font collections.
- Automatic kerning and font layout.
- Horizontal and vertical text layout.
- Left-to-right and right-to-left text layout.
- Uses fallback fonts if a character is not available from one font.
- Can Align text left/center/right/vertical
- Line Wrapping
- Arabic and other script text shaping
- Better interoperability for monospace when mixing scripts.
Add the following to your Cargo.toml.

Contributors are always welcome (thank you for being interested!), whether it be a bug report, bug fix, feature request, feature implementation or whatever. Don't be shy about getting involved. I always make time to fix bugs, so usually a patched version of the library will be out a few days after a report. Features requests will not complete as fast. If you have any questions, design critques, or want me to find you something to work on based on your skill level, you can email me at jeronlau@plopgrizzly.com. Otherwise, here's a link to the issues on GitHub. Before contributing, check out the contribution guidelines, and, as always, make sure to follow the code of conduct.
