title: Can Mathematica create multi-page PDF files?
body: <p>When one imports a multi-page pdf file (the file I have in mind contains images of artwork, one per page) into Mathematica 8.0.1 by</p>
  
  <blockquote>
    <p>book = Import["simple.pdf"]</p>
  </blockquote>
  
  <p>Mathematica returns a list of graphics objects, one for each page. I have some manipulations I perform on each page, and then want to save the changed pages back into a single PDF file</p>
  
  <blockquote>
    <p>Export["DistortedSimple.pdf", distortedbook]</p>
  </blockquote>
  
  <p>the resulting file has all of the images on a single page. Is there a convenient way to export a list of images to PDF, one per page?</p>
