title: Converting a PDF into multiple JPGs with iText or other
body: <p>I have the need to convert any multipage PDF file into a set of JPGs.</p>
  
  <p>Since the PDF files are <em>supposed</em> to come from a scanner, we can assume each page just contains a graphic object to extract, but I cannot be 100% sure of that.</p>
  
  <p>So, I need to convert any renderable content from each page into a single JPEG file.</p>
  
  <p>How can I do this with iText?</p>
  
  <p>If I can't do this with iText, what Java library can achieve this?</p>
  
  <p>Thanks.</p>
