i was refering to a possibly non-rectangular shape. i am not used to gridflow but i would guess that it is possible to take the mean color over a group of pixels.
actually the fastest way to do this in GridFlow is to use [#store]. This one is hard to beat. You put your image in the [#store], then you recall areas of it by sending a list of positions (a N-by-2 grid) and you will get a list of RGB pixels (a N-by-3 grid), which you can then average by using [#fold + (0 0 0)] and [# /].
