Abstract:

   NUp page definition. This class is responsible for maintaining
   the current NUp page. The public interface defines methods for adding
   fixed page content and closing the current page. When a page is added,
   the class uses a SAX handler to strip the FixedPage tags from the
   source page, apply a canvas with a transformation and add it to the
   current NUp page. When the page is full it is closed and sent and a new
   NUp page is created.
