// .NAME vtkImageShiftScale - shift and scale an input image
// .SECTION Description
// With vtkImageShiftScale Pixels are shifted (a constant value added)
// and then scaled (multiplied by a scalar. As a convenience, this class
// allows you to set the output scalar type similar to vtkImageCast.
// This is because shift scale operations frequently convert data types.

// Description:

// the output value does not exceed the max or min of the data type.
// Clamping is safer because otherwise you might invoke undefined
// behavior (and may crash) if the type conversion is out of range
// of the data type. On the other hand, clamping is slower.
// By default, ClampOverflow is off.
