title: Highlight words inside existing PDF
body: <p>I need to highlight a set of words inside an existing PDF given specific coordinates that i have already extracted.
  I am working with pdfbox by Apache (last version 2.0.8).
  There is an example file I can use to such a purpose (AddAnnotations.java inside the pdfbox website) but I think this example was compiled with an older Java version as the following import does not work:</p>
  
  <p><code>import org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationHighlight;</code></p>
  
  <p>Can anyone help me with that? Which is the simplest way to highlight words by using this library?</p>
