First, this is my first attempt at posting.  Please forgive me if it looks
very bad.  I hope it goes on the net.

Anyway, my need is great, as they say.  What I am looking for is an FFT
program for the Amiga.  I am an Imaging Science student at RIT and need
this program to show some people around here what an Amiga can do.  They
are presently using a PDP/11 and a Mac, etc.

What I would like it to do is load an image (B/W is fine) take the FFT,
display the real and imaginary and power spectrum (chosen from menus).
Then I would like to be able to 'paint' over the frequency space (edit
individual values), and then back transform to see the difference.

I would do it myself, but not knowing C, it is unlikely.  If anyone is
interested, I do have the code necessary (in Fortran or Pseudo-code). If
anyone knows of a program that exeists now to do even a simple FFT, DFT,
or any variation thereof, I would gladly recompense the author.

Thank You very much,
