Hi guys!

It is again me, this time in English. So, I am still trying to create a new
FFT Image in which I can manipulate the pixels in the frequency domain and
then to transform the image back into the spatial domain.

This is a macro of the commands I performed with ImageJ 1.36b

open("E:\\Maja\\Eigene Bilder\\lena.gif");
run("FFT");
makeOval(197, 202, 121, 118);
run("Fill");
run("Duplicate...", "title=[FHT of lena.gif]");
run("Inverse FFT");

I still get the error message:

Frequency domain image required.

Could anyone send me his macro for manipulating the FFT, duplicating the
FFT or FHT and then doing the inverse FFT?
