Color depth image converter.

Required Methods

fn convert_image_with_loss( &self, image: &RgbImage, options: ColorOptions ) -> (Vec<Color>, u64)

Convert and retrieve the loss from converting an image.

Provided Methods

fn convert_image(&self, image: &RgbImage, options: ColorOptions) -> Vec<Color>

Convert an RGB image to this color depth.

fn loss(&self, image: &RgbImage, options: ColorOptions) -> u64

Estimate the loss obtained from converting an image. For the best results, greater discrepancies should result in higher loss values.

Implementations on Foreign Types

impl<'a, T: ColorDepth> ColorDepth for &'a T

fn convert_image(&self, image: &RgbImage, options: ColorOptions) -> Vec<Color>

Convert an RGB image to this color depth.

fn loss(&self, image: &RgbImage, options: ColorOptions) -> u64

Estimate the loss obtained from converting an image. For the best results, greater discrepancies should result in higher loss values.
