You will need to install hitherdither from GitHub:
sudo python3 -m pip install git+https://www.github.com/hbldh/hitherdither
usage: ./dither.py <image_file> <saturation>
- Image file should be RGB and can be a jpg, PNG or otherwise.
- Saturation should be from 0.0 to 1.0 and changes the palette that's used to dither the image.
a higher saturation will generally result in a more saturated end image due to how colours are mixed.
