Cropping after warp

[RpfR2000]

Warping produces NaN values, by default. Is there a built-in way to crop the regions of the image that contain NaN? For example, I have a stack of images that I have registered. They all have NaN (except the first in the stack) due to the warp. Is there a way to efficiently crop to the maximal size that preserves all non-NaN values? I couldn't find anything in the docs. If not, no problem.

I don't remember anything built in. It might be worth adding. Care to try making a PR?

Sure! I'll get to it later this week.
