epd2in13: use better black/white approximation #616

Closed aykevl closed 10 months ago

aykevl commented 11 months ago

The previoius behavior was that entirely black pixels were treated as white, and anything else as black. That's at least counter-intuitive. This patch changes the behavior to actually look at the color values and use a cutoff around medium gray: darker colors are treated as black, and lighter colors are treated as white.

This is a backwards incompatible change, but I think this behavior makes a lot more sense.

Thanks for improving this @aykevl and to @conejoninja for review. Now merging.
