// .NAME vtkImageIdealLowPass - Simple frequency domain band pass.
// .SECTION Description
// 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.
