// .NAME vtkImageGradientMagnitude - Computes magnitude of the gradient.
// .SECTION Description
// vtkImageGradientMagnitude computes the gradient magnitude of an image.
// Setting the dimensionality determines whether the gradient is computed on
// 2D images, or 3D volumes. The default is two dimensional XY images.
// .SECTION See Also
// vtkImageGradient vtkImageMagnitude
