/**
* @class vtkImageGradient
* @brief Computes the gradient vector.
*
* vtkImageGradient computes the gradient vector of an image. The
* vector results are stored as scalar components. The Dimensionality
* determines whether to perform a 2d or 3d gradient. The default is
* two dimensional XY gradient. OutputScalarType is always
* double. Gradient is computed using central differences.
