What is this

This is a command-line tool that converts an image to a limited colorspace, utilizing dithering.

Currently, the following options are hardcoded:

• the 1bit color palette is hardcoded
• the desired output resolution

You can modify these in src/bayer.rs. However, it is my plan to make those user configurable.

eg:

note: Currently level works internally like [1,level]. It will generate all levels from 1 to the level you provide. I might change this behavior in the future.
