title: itextsharp measure chunk width / height
body: <p>I am trying to do some precise alignment with iTextSharp, but I keep falling short as I can't figure out a way to get a width / height value for a chunk or paragraph.    If I create a paragraph that is  a certain font and size and text, then its dimensions should be known, right?</p>
  
  <p>I know that the default left/right/center alignments will do the trick for me mostly, but I have scenarios where knowing the dimensions will be most useful.  Any ideas?</p>
