Trait dither::ditherer::Dither

pub trait Dither {
    const DIV: f64;
    const OFFSETS: &'static [(isize, isize, f64)];
    fn dither<P>(
        img: Img<P>, 
        quantize: impl FnMut(P) -> (P, P)
    ) -> Img<P>
    where
        P: Add<Output = P> + Mul<f64, Output = P> + Div<f64, Output = P> + Clone + Default,
    { ... }
}

A type of Dither. Available dithers are Stucki, Atkinson, FloydSteinberg, Burkes, JarvisJudiceNinke, Sierra3. See tanner helland's excellent writeup on dithering algorithms for details.

    quantize: impl FnMut(P) -> (P, P)
) -> Img<P> where
    P: Add<Output = P> + Mul<f64, Output = P> + Div<f64, Output = P> + Clone + Default, 

dither a 2d matrix. P is the type of pixel (u8, [RGB<f64, f64, f64>]); S is multiplible and divisble by a SCALAR but adds to ITSELF
