title: TextMarginFinder to verify printability
body: <p>I am attempting to use TextMarginFinder to prove that odd and even pages back up correctly when printing. I have based my code on:
  <a href="http://itextpdf.com/examples/iia.php?id=280" rel="nofollow">http://itextpdf.com/examples/iia.php?id=280</a></p>
  
  <p>The issue I have is that on odd pages I am looking for the box to be aligned to the left showing a 1CM back margin for example, and on an even page I would expect the page box to be aligned to the right also showing a 1CM back margin. Even in the example above this is not the case, but when printed the text does back up perfectly because the Trim Box conforms.</p>
  
  <p>In summary I believe on certain PDF files the TextMarginFinder is incorrectly locating the text width, usually on Even pages. This is evident by the width being greater than the actual text. This is usually the case if there are slug marks outside of the Media Box area.</p>
