title: Reverse backward text from a pdf file?
body: <p>The texts looks like this "stnetnoc." only even the letters are facing the wrong direction. And the pages displayed its side at the bottom and the top. </p>
  
  <p>I'm not familiar with pdf coding or manipulation libraries.</p>
  
  <p>There's a post suggesting another user to use printer to print the file reverse and it'll reverse the orders for the printed files. Ordering of the pages isn't the problem in my case, and I want to avoid printing the entire document since it's quite massive.</p>
