title: pdftron webviewer - how to save the whole edited pdf to server with php
body: <p>I am currently a developing an application that is using a <code>PDFTron</code> webviewer. Is there anyway to save the edited pdf edited with <code>pdftron</code> webviewer to the server?</p>
  
  <p>There is a feature of <code>pdftron</code> that saves annotations to the server, but I need to save the whole pdf with the edits to the server.</p>
