`quantette` is a library for fast and high quality image quantization and palette generation.
It supports the sRGB color space for fast color quantization but also the CIELAB and Oklab
color spaces for more accurate quantization. Similarly, `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`](https://crates.io/crates/wide) crate).
Consider enabling the `avx` or `avx2`
[target features](https://doc.rust-lang.org/reference/conditional-compilation.html#target_feature)
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.

See [Examples](docs/Examples.md) for example output images from `quantette`
and see [Benchmarks and Accuracy](docs/Benchmarks%20and%20Accuracy.md) for comparisons with other libraries.
