title: Null value PDF file
body: <p>Anyone seen or know how to generate a completely null-value PDF file? Not a blank page, just null. Or at the most a single pixel line.</p>
  
  <p>I got some software that appends a pdf file to every pdf being generated. They decided they don't want that last pdf anymore.</p>
  
  <p>Rather than recompile and redistribute, I would rather drop a blank PDF in there.</p>
  
  <p>However every PDF editor I uses wont let me crop it down less than 1 inch, resulting in a little 1 inch strip after the document.</p>
  
  <p>Suggestions?</p>
