title: How to extract images from a scanned pdf
body: <p>I use Tesseract to extract text from scanned PDF. Some of these files also contain images. Is there a way to get those images? </p>
  
  <p>I prepare my scanned pdf for tesseract by converting them in tiff files. But I can't find any command line tool to extract images from them, as pdfimages would do for "text" pdf.</p>
  
  <p>Any idea of a tool (or a combination of tools) that would help me do the job?</p>
