Perhaps the parent class documentation will help?

The HTML documentation is really useful.

Better still use Python and check it for yourself on the
interpreter. :)

$ python
>>> from vtk import *
>>> i = vtkImageGradientMagnitude ()
>>> i.GetOutput()
<libvtkCommonPython.vtkImageData vtkobject at 0x821a3a8>
>>> print i.GetOutput()
vtkImageData (0x8207318)
