GridFlow can do this.

http://gridflow.ca

Most GridFlow objects operate on whole grids (of which images are a
subset), but there are ways to get regions from grids (using #store) and
ways to put regions back into a certain place in an image (using
#draw_image).

There is also a Gem<->GridFlow bridge (part of GridFlow).
