# Dither

This library is a rustler NIF for Elixir which provides support for some basic
image manipulation functions, as well as dithering. Supported functions include:

- load an image from file
- save an image to file
- decode an image from bytes
- encode an image to bytes
- resize an image
- flip an image
- convert an image to grayscale
- dither an image with various algorithms
- ... and more

The dithering functions wrap the excellent
[`dither`](https://gitlab.com/efronlicht/dither) library from Efron Licht.
