/** \class ShiftScaleInPlaceImageFilter
* \brief Shift and scale the pixels in an image.
*
* ShiftScaleInPlaceImageFilter shifts the input pixel by Shift (default 0.0)
* and then scales the pixel by Scale (default 1.0). All computattions
* are performed in the precision of the input pixel's RealType. Before
* assigning the computed value to the output pixel, the value is clamped
* at the NonpositiveMin and max of the pixel type.
*
* ShiftScaleInPlaceImageFilter overwrites the input image to form the
* output image. If you do not want the input data destroyed, use the
* ShiftScaleImageFilter instead.
