[Radiance-general] Cropping a .pic file

[Greg Ward]

Hi Krystyna,

Can you share a few more details?  What were the exact view parameters you gave to rpict, and do you need to compute circular area averages or would rectangular areas work?

This can probably be done with pcomb without needing to crop the images, but some math is required.
