title: iText setRotateContents(false) strange behaviour on Landscape PDF's?
body: <p>I have concatenated several PDF files, some of which were landscape. I am now stamping each page of the final PDF.</p>
  
  <p>I have realised that not using <code>setRotateContents(false)</code> will result in your modification being added at -90 degrees to where you expect. Except some of my landscape pages actually correctly position the modification at this stage at 0 degrees.</p>
  
  <p>If I use <code>setRotateContents(false)</code> then all of these modifications are rotated clockwise 90 degrees meaning most of my page modifications on landscape pages are now correct at 0 degrees but some of my landscape pages are now at +90 degrees.</p>
  
  <p>The problem is I can't work out what is causing my pages to give this strange behaviour? They both are using very similar code to generate the reports.  Has anyone seen a similar problem before?</p>
