Sweet.

I immediately modded it to a single channel (greyscale) and figured out how to "mask" the calculations. (set unwanted blackpoint areas to white, and vice versa)

Cool! Its useful as a snippet for ensuring maximum heightmap range usage. For input images though I think this is possible to do much faster with the existing min/max comps? Ofcourse not as cool as this solution smile:D

Would you be kind enough to explain how one would do this? A fast way to get the Min/Max and autolevel a grayscale source would be immensely helpful in my current project.

Thanks in advance, assuming you notice this and care to respond.

Edit: I found the thread where all of this is explained, so thanks for reading, if you have, but you don't have to address the question unless you want to elaborate on something.
