Dr. Drang solves my problem
I had a problem. I wanted to put a stray E-Ink device, which I had sort of given up on, back into action. It has a color screen, but my attempts to write out color graphics were coming up empty. I turned to the Internet’s Dr. Drang for help:
A week or so ago, Jason Snell asked if I could help with a problem he was having using the Python Imaging Library (PIL) . He wanted to update his e-ink status board with color images, as he now has the color e-ink display that Dan Moren uses. But he couldn’t get consistent results as he tried to use PIL to change the color of black pixels to different colors in a set of GIF images that were overlaid on his calendar background.
