Ditherings

Dithering Algorithms for Julia

Basic Usage Examples

julia> using Ditherings

Simple Reduced Precision Colour

julia> img = load("lenna.png");

Switch to zero or one per pixel

julia> Ditherings.FloydSteinbergDither4Sample(img, Ditherings.ZeroOne)

Switch to zero or one per channel

julia> Ditherings.FloydSteinbergDither4Sample(img, Ditherings.ZeroOne_PerChannel)

Approach

The aim of these funcions is that you can call a function which represents an error diffusion shape, and then pass in a palette function which maps the input function into the reduced precision space. Optionally you can also pass in custom weights for the error diffusion kernel
