/**
* @class vtkImageIdealLowPass
* @brief Simple frequency domain band pass.
*
* This filter only works on an image after it has been converted to
* frequency domain by a vtkImageFFT filter. A vtkImageRFFT filter
* can be used to convert the output back into the spatial domain.
* vtkImageIdealLowPass just sets a portion of the image to zero. The result
* is an image with a lot of ringing. Input and Output must be doubles.
* Dimensionality is set when the axes are set. Defaults to 2D on X and Y
* axes.
