title: Set PDF Version using iTextSharp
body: <p>Anyone know how to save a PDF as a lower PDF version programmatically using iTextSharp so that you can use certain iTextSharp features that require the PDF to be version 5 or lower?</p>
  
  <p>I'm trying to merge two PDF version 7 documents together and it insists that they be version 5 or lower.</p>
