Does quantization in pure rust on Rgba image, using https://crates.io/crates/image
algorithm: https://observablehq.com/@tmcw/octree-color-quantization
inspired by to https://github.com/objectProfessionals/movieMaps
fn test_big_image() -> Result<(), ImageError> { let src: RgbaImage = image::open("some_image.jpg").unwrap().into_rgba8();
let out = quantize(&src, 256);
out.save_with_format("output.jpg", image::ImageFormat::Jpeg)?;
Ok(())
}
