 * pixels.
 *
 * This filter is templated over the input image type and
 * output image type. The each dimension of the output image pixel is
 * filled with each input image pixel's scalar pixel value. This
 * filter can be used to cast a scalar image to a vector image if
 * there is only one input image.
