Trait Implementations

impl<C: Clone> Clone for BestPalette<C>

fn clone(&self) -> BestPalette<C>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn convert_image_with_loss(
    &self,
    image: &RgbImage,
    num_colors: Option<u32>
) -> (Vec<Color>, u64)

Convert and retrieve the loss from converting an image.

fn convert_image(&self, image: &RgbImage, num_colors: Option<u32>) -> Vec<Color>

Convert an RGB image to this color depth.

fn loss(&self, image: &RgbImage, num_colors: Option<u32>) -> u64

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