/**
 * @class   vtkImageStencilToImage
 * @brief   Convert an image stencil into an image
 *
 * vtkImageStencilToImage will convert an image stencil into a binary
 * image.  The default output will be an 8-bit image with a value of 1
 * inside the stencil and 0 outside.  When used in combination with
 * vtkPolyDataToImageStencil or vtkImplicitFunctionToImageStencil, this
 * can be used to create a binary image from a mesh or a function.
