/**
* @class vtkImageToPoints
* @brief Extract all image voxels as points.
*
* This filter takes an input image and an optional stencil, and creates
* a vtkPolyData that contains the points and the point attributes but no
* cells. If a stencil is provided, only the points inside the stencil
* are included.
* @par Thanks:
* Thanks to David Gobbi, Calgary Image Processing and Analysis Centre,
* University of Calgary, for providing this class.
