# Credits

# stb_truetype

RFont uses [stb_truetype](https://github.com/nothings/stb) for working with fonts.

A modified version of stb_truetype is included in the RFont header.\

But you can use an external copy by adding `#define RFONT_EXTERNAL_STB` to your code

# Fontstash

[Fontstash](https://github.com/memononen/fontstash) is another font rendering library with simular goals.

Fontash was used as a reference for some of this code. 

However, this library is intended to have better perfromance and be more lightweight than fontstash.
