Trait exoquant::ditherer::Ditherer

pub trait Ditherer {
    fn remap<'a>(
        &'a self, 
        image: Box<Iterator<Item = Colorf> + 'a>, 
        width: usize, 
        map: &'a ColorMap, 
        colorspace: &'a ColorSpace
    ) -> Box<Iterator<Item = usize> + 'a>;
}

An interface for dithered color remapping.

End users of this library will most likely not call ditherer::remap directly, but rather use the Remapper helper.

Required Methods

fn remap<'a>(
    &'a self,
    image: Box<Iterator<Item = Colorf> + 'a>,
    width: usize,
    map: &'a ColorMap,
    colorspace: &'a ColorSpace
) -> Box<Iterator<Item = usize> + 'a>

Remaps an iterator of input pixel (float-)colors of an Image to an Iterator of palette indices.
