Hi Daniel,
The destination image should remain the same size as the source. The
RescaleOp is just a radiometric operator and will only change the intensity
of the pixel. The ConvolveOp is a spatial operator that will change the
intensity of a pixel given the values of the neighboring pixels and a
kernel. If you want to transform the image, you may want to use
AffineTransformOp.
