dither-nim
Dithering algorithms implemented in Nim
API
Algorithms
This library supports two primary classifications of algorithms:
- Ordered Dithering: This is a fast dithering algorithm that uses a matrix of predefined values to vary what color is selected.
- Error Diffusion: A slightly slower dithering algorithm that tracks the error incurred when a color is clamped to the palette, then distributes that error to surrounding pixels.
A more detailed list of supported algorithms can be found here:

Example
A working example that uses pixie for images and chroma for colors can be seen here:

A note on concepts
This library uses Nim concepts to control the inputs to its algorithms. This allows it to integrate with arbitrary image, color, and palette libraries -- as long as they implement the interface described by the concepts.
