title: Why does pdftoppm poppler-utils have no jpeg option?
body: <p>On Ubuntu 10.04, I've installed the poppler-utils package to be able to run pdftoppm.</p>
  
  <p>My goal is to convert PDFs to jpegs, however I don't have that option/flag available. The only rasterizer I seem to have is PNG support.</p>
  
  <p>Could someone please advise how I can get jpeg support? Many thanks.</p>
  
  <p>(See my options list below after running: pdftoppm --help):</p>
