[vtkusers] Problems with imaging FFT data

[Vidyadhar]

Hi,
If you want spectrum you can use vtkImageMagnitude, you can use 
vtkImageExtractComponents to extract real (0) or imaginary (1) part, or use 
vtkImageEuclideanToPolar and vtkImageExtractComponents to extract phase (0) 
and magnitude component of the spectrum. You may want to use 
vtkImageFourierCenter to center the image before processing.

Subject: [vtkusers] Problems with imaging FFT data


Hi

i have one problem with the FFT. I don't know how to create an image and 
display this image. After my VTKFFT i get a real and a imaginary part. when 
i do the RFFT of this vtkImageData everything works fine. But i need to 
display the result of the FFT too. Can somebody help me please?

thanks Stefan
