Function exoquant::convert_to_indexed

pub fn convert_to_indexed<D, O>(
    image: &[Color], 
    width: usize, 
    num_colors: usize, 
    optimizer: &O, 
    ditherer: &D
) -> (Vec<Color>, Vec<u8>) where
    D: Ditherer,
    O: Optimizer, 

A convenience function to simply quantize an image with sensible defaults.

Examples:

let (palette, indexed_data) = convert_to_indexed(&image.pixels, image.width, 256,
  &optimizer::KMeans, &ditherer::FloydSteinberg::new());
