Extensive, fast, and accurate command-line image dithering tool

didder is an extensive, fast, and accurate command-line image dithering tool. It is designed to work well for both power users as well as pipeline scripting. It is backed by the author's dithering library (https://github.com/makew0rld/dither), and is unique in its correctness and variety of dithering algorithms. It provides many options, while being correct (linearizing the image, weighting channels by luminance).

Types of dithering supported

 * Random noise (in grayscale and RGB)
 * Ordered Dithering
   * Bayer matrix of any size (as long as dimensions are powers of two)
   * Clustered-dot - many different preprogrammed matrices
   * Some unusual horizontal or vertical line matrices
   * Yours? You can provide your own ordered dithering matrix in JSON format
 * Error diffusion dithering
   * Simple 2D
   * Floyd-Steinberg, False Floyd-Steinberg
   * Jarvis-Judice-Ninke
   * Atkinson
   * Stucki
   * Burkes
   * Sierra/Sierra3, Sierra2, Sierra2-4A/Sierra-Lite
   * Steven Pigeon (https://hbfs.wordpress.com/2013/12/31/dithering/)
   * Yours? You can provide your own error diffusion matrix in JSON format

Features

 * Set palette using RGB tuples, hex codes, number 0-255 (grayscale), or
   SVG color names (https://www.w3.org/TR/SVG11/types.html#ColorKeywords)
 * Optionally recolor image with a different palette after dithering
 * Set dithering strength
 * Image is automatically converted to grayscale if palette is grayscale
 * Force image to grayscale with --grayscale
 * Change image saturation, brightness, or contrast before dithering
 * Read EXIF rotation tags by default (disabled with --no-exif-rotation)
 * Downscale image before dithering, keeping aspect ratio
 * Upscale image after dithering, without producing artifacts
 * Supports input image of types JPEG, GIF (static), PNG, BMP, TIFF
 * Output to PNG or GIF
 * Process multiple images with one command
 * Combine multiple images into an animated GIF
 * Uses all CPU cores when possible
 * Support images with transparency (alpha channel is kept the same)
