Abstract:

   Watermark filter defnition. This class derives from the Xps filter
   class and implements the necessary part handlers to support Watermark
   printing. The Watermark filter is responsible for adding resources to
   the XPS document and putting the appropriate mark-up onto pages with a
   watermark
