Struct surf_n_term::image::ColorPalette[−][src]

pub struct ColorPalette { /* fields omitted */ }

Color palette which implements fast NNS with euclidian distance.

Implementations

impl ColorPalette[src]

pub fn new(colors: Vec<RGBA>) -> Option<Self>[src]

Create new palette for the list of colors

pub fn from_image(
    img: impl Surface<Item = RGBA>,
    palette_size: usize,
    bg: RGBA
) -> Option<Self>[src]

Extract palette from image using OcTree

pub fn size(&self) -> usize[src]

pub fn get(&self, index: usize) -> RGBA[src]

Get color by the index

pub fn colors(&self) -> &[RGBA][src]

List of colors available in the palette

pub fn find(&self, color: RGBA) -> (usize, RGBA)[src]

Find nearest color in the palette

Returns index of the color and color itself

pub fn find_naive(&self, color: RGBA) -> (usize, RGBA)[src]

Find nearest color in the palete by going over all colors

This is a slower version of the find method, used only for testing find correctness and speed.
