Dscho-

I've addressed my original problem by using ImageProcessor.resize().

But I'm stuck mentally on your argument about the squares.  What's the
alternative?  Circles?  I thought that the pixels in our cameras were
actually squares.  Are they a different shape, either physically or
functionally?  Does anyone do math to account for their actual shape?  
Maybe in astronomy?

Very interested in the details of what's correct, even if my own imaging
never reaches the precision needing this sort of rigor.

Thanks,
Bill
