title: Pdf Signature Validity Check Mark Not Visible on Acrobat Reader
body: <p>I am signing a pdf file with iText. When I view the file on Acrobat Reader 9, the green tick does not appear inside the signature rectangle as it used to do in Acrobat Reader 7. </p>
  
  <p>Note that I can see the validity mark on top of the page, but I specifically want the mark to appear in the signature rectangle. </p>
  
  <p>Some say that this feature is no longer supported by Acrobat by version 9, however I have viewed some digitally signed files with the green check mark on version 9.</p>
  
  <p>So, is there a specific flag or layer on itext I need to use? I already use setAcro6Layers, setVisibleSignature, setLayer2Text, setLayer2Font, setImage, setImageScale etc..</p>
  
  <p>Any help is much appreciated.
  thanks</p>
