* @class vtkImageGradientMagnitude
* @brief Computes magnitude of the gradient.
*
*
* 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.
