Exporting FFT result like GIMP plugin

Software G'MIC
3

Thank you very much, you’re king among people! :smiley: Looks like it is what I need.
But I have some questions:
0. Where can I read about -gimp_fourier switch? I didn’t find it @ http://gmic.eu

  1. First digit in command means direction of conversion: 0 — direct, 1 — inverse, right?
  2. Resulting image have size _orig_height_×6+2, who are these extra pixels? :slight_smile:

Thanks in advance :relaxed:
