title: ghostscript BoundingBox values
body: <p>I'm just asking myself, what are those bbox values printed out by:</p>
  
  <pre><code>gs -dSAFER -dNOPAUSE -dBATCH -sDEVICE=bbox myfile.pdf
  
  %%BoundingBox: 46 911 1668 4537
  %%HiResBoundingBox: 46.080002 911.520035 1667.520064 4536.000173
  </code></pre>
  
  <p>top-left-X, top-left-Y, ....?</p>
  
  <p>And what's the measurement of those values (1/72")?</p>
  
  <p>Thanks for helping</p>
