Hi,

From the source:

        This class implements the FFT, Inverse FFT and Redisplay Power
        Spectrum commands in the Process/FFT submenu. It is based on Arlo
        Reeves' Pascal implementation of the Fast Hartley Transform from NIH
        Image (http://rsb.info.nih.gov/ij/docs/ImageFFT/).

That was exactly the reason why I did not suggest accessing the ImageJ
plugin in my reply: the OP asked for an FFT, not an FHT.

Ciao,
