Thanks to you too, I had just started looking at that a few days ago and thought
I would try layering images to combine them. Didn't get far but on a whim I
changed to interpolate 3 for the input image and got an interesting result.

Reading the docs to refresh my memory on that bicubic interpolation it says
there could be a sharpening effect on certain color boundaries. So that probably
explains the peculiar outlines seen in these pattern blend renderings if
interpolate 3 is used.
