Hello Kurt!

That worked wonderfully.  Thank you for the great example.  It allowed me to see a problem with my pasting... my destIndex comes from a registration, and I can see that the parameters from the Optimal translation are incorrect.  It gives me them as negative numbers, but to get the srcImage onto the destImage I had to multiply both by -1.  I guess for registration down vertically is negative, but for pasting it is positive.
