Hi Mark,

There will undoubtedly be a far better answer to your post but I might
be able to get you thinking.

You seem to be using it correctly. :)

The difference is that in object graphics your scaling doesn't actually
change the objects data. Your second approach (using congrid)operates
on the image data itself and "scaling" the image smaller will result in
lost data.
