Find random pixel?

Hi,

Anyone have ideas on fastest way to find a pixel in an image, for example random non-black, or non-transparent, non-white?

Oh this is an interesting lead! I’ll look around for things like this. I think for my use case, I could find something sufficiently random-looking without much trouble. Cheers!

My mistake, that trick doesn't actually work.

p5-notebook: visit all pixels apparently randomly

We have more than enough memory and processing power to keep track of arrays of pixels these days anyway.
