Abstract:

   Booklet filter SAX handler definition. The booklet SAX handler derives
   from the default SAX handler and implements the necesary SAX interfaces to
   process fixed page mark-up for booklet printing.
   For documents with odd page counts, we add a blank padding page so that the
   2-Up behaves correctly. All that is required of the handler is to retrieve
   the fixed page open tag and write this out.
