quantette

quantette is a library for fast and high quality image quantization and palette generation. It uses the Oklab color space for more accurate quantization (but still supports sRGB and other color spaces). quantette's k-means color quantizer gives high quality results while the included Wu color quantizer gives fast but still quite good results.

In some critical locations, quantette makes use of SIMD (via the wide crate). Consider enabling the avx or avx2 target features for a noticeable speed up if your target architecture supports these features. If the threads cargo feature is enabled, multi-threaded versions of most functions become available for even greater speed up.
