Uh, can't you?

I'd think that the information in an image is just so many numbers that 
you could convert to a function and manipulate as you would any other 
pattern.

Or are you talking about some kind of post-processing for images that 
POV-Ray creates? In that case, yes, you'll have to wait until MegaPOV 
gets its post-processing filters back, unless you want to feed the image 
back into POV-Ray as an image map, point an orthographic camera at it, 
and try to manipulate it that way...
