Calculates forward and inverse Fourier transforms. Uses a real, 2D Fast Hartley Transform (FHT) routine contributed by Arlo Reeves, the author of ImageFFT. The frequency domain image is displayed as an 8-bit log scaled power spectrum with the 32-bit FHT as an image property. Editing, filtering, crosscorrelation and autocorrelation capabilities will be added in a future version.
