             This does say that there are magic value blanks in the
image.  If you FFT magic values you get trash everywhere.

      CONVL may also have trouble with these dimensions although it
appears to be smart enough to do 2048x4096 FFTs.

The message comes out when magic values are actually found.  You can
REMAG them to zero or some other value - but you should know why they
are there and where they are.  On the TV magic values stay black no
matter what transfer function you use.
