No, it doesn't. Bob, please point me to exactly where Nyquist theorum
deals with image detail. There I was thinking that the Nyquist-Shannon
theorum only dealt with frequencies.

What I find most revealing is that NO-ONE has dealt with exactly how one
should do to end up with the decimated, required resolution image.
