This ForwardFFTFromImage Method performs a forward Fast Fourier Transform of the input image. The difference between this method and ForwardFFT is that this method takes an ImGearPage Class as the input object.

You must keep track how the transform is centered, as well as the scaling method, in the forward FFT in order to know how to de-center it during the inverse FFT. |
This method can be applied only to 8, 16, or 32bit grayscale images with one channel.
ImGearFrequencyProcessingVerifier.CanApplyForwardFFTFromImage Method can be called to check whether the operation can be performed or not.
