Image Quantizer

j'bang script to quantize an image to a colour palette.

Heavily inspired by ImageGoNord.

By default it applies a (linear) pre blur to the image to reduce noise, then quantizes each pixel to one of the colours in the Monokai colour scheme.

Running

Requires j'bang to run

jbang ImageQuantizer.java input-image.png output-image.png

Hacking

To use a different scheme, make a list of java.awt.Color, and pass it to ImageQuantize.quantizeImage instead of MONOKAI in the main method.

Demo

Run make in the root to replicate this demo

Limitations

  • The image is always output in .png format, no matter what extension you specify the output image to have.
