Interface
SpectralFilter2D is used by operation
spectralhomomorphicfilter in rendered and
renderable mode.
The lifecycle of this interface is simple. First are called
SpectralFilter2D.setWidth(int) and
SpectralFilter2D.setHeight(int) to set the bounds of
the image. Then
SpectralFilter2D.getFilterImage(int,RenderingHints) is called to get
the filter image.
The filter image must be complex (have an even number of band, twice that of
the desired number of elements) and centered.
