Wow thank you all! I tried Image Magick and it worked great at 80% dithered thank you Kirk! I can’t believe that GIMP has this option and not Affinity Photo.

Thanks! Is there a way to reduce the colors to 7 and then I can change the colors to the ones specified in that guide?

In photoshop I can export images under the "Save for Web (Legacy)" Im trying to covert photos into 7 colors that can be supported for color e-paper from wave share display. Please see below for the instructions im trying to recreate in affinity photo. https://www.waveshare.com/wiki/E-Paper_Floyd-Steinberg
