dithord: Bayer ordered dithering crate

This crate provides functionality which allows for monochromatic ordered dithering using a Bayer threshold matrix. This method of dithering is less accurate than others but is fast and visually appealing.

Currently only monochromatic dithering is supported, but support for arbitrary palettes could be considered as a feature.

Add to Project

cargo add dithord

Usage

This crate provides the OrderedDither trait which is implemented for image::DynamicImage, along with a ThresholdMap struct for generating and storing the Bayer matrix.

Example

use dithord::{ThresholdMap, OrderedDither};
use image::{io::Reader};

fn main() {
    let mut image = Reader::open("example.png").unwrap().decode().unwrap();

    // Generate level 2 (8x8) threshold map
    let map = threshold_map::ThresholdMap::level(2);
    // Apply dither
    image = image.ordered_dither(map);
}
