ForwardFFTFromImage Method

Description:

Performs a forward Fast Fourier Transform of the input image. The difference between this method and ForwardFFT is that this method takes an IGPage Object as the input.

Syntax:

      ForwardFFTFromImage (pPage As IGPage, nScalingMethod As
enumIGFFTScalingMethods, bCenterTransform As Boolean) As
IGComplexObject

Parameters:

Name	Description
pPage	IGPage Object to process.
nScalingMethod	Specifies the method of scaling the result data.
bCenterTransform	Flag to indicate whether to center the transform.

Return Value:

Returns an IGComplexObject Object, which contains result data.

Bits Per Pixel:

8, 16, or 32bit grayscale images with one channel
