[CentralOH] Python library for image processing?

[Eric Miller]

thanks Eric   I do indeed plan on doing an operation on every pixel in the
image.  Sounds like I may need to use a few libs to achieve it efficiently.

The goal is to parse Kerbal Space Program biome map images
<https://wiki.kerbalspaceprogram.com/wiki/Biome>, to determine the landing
spots that are nearest to the most number of surface biomes.
