/** \class PointSetFunction
* \brief Evaluates a function of an image at specified position.
*
* FIXME: Documentation was copy-pasted from ImageFunction.
*
* PointSetFunction is a baseclass for all objects that evaluates
* a function of an image at index, continuous index or point.
* This class is templated over the input image type, the type
* of the function output and the coordinate representation type
* (e.g. float or double).
*
* The input image is set via method SetInputPointSet().
* Methods Evaluate, EvaluateAtIndex and EvaluateAtContinuousIndex
* respectively evaluates the function at an geometric point,
* image index and continuous image index.
*
* \warning Image BufferedRegion information is cached during
* in SetInputPointSet( image ). If the image BufferedRegion has changed
* one must call SetInputPointSet( image ) again to update the cache
* to the current values.
