title: iTextSharp - Adding a vertical textbox
body: <p>Does anyone know if it's possible to add a vertical textbox to a PDF document using itextsharp.</p>
  
  <p>I have tried rotating the page first </p>
  
  <pre><code>PdfDictionary pDict = reader.GetPageN(1);
  pDict.Put(PdfName.ROTATE, new PdfNumber(90));
  AddTextBox(stamper, ...........)
  // Rotate back
  </code></pre>
  
  <p>but this just adds the textbox horizontally, do I need to get another instance of stamper after the rotation?</p>
