PDF link extraction and analysis.

Q: I need to analyze a PDF document and
extracts the embedded hyperlinks + information on the relative
position of these links.

A:
The Annotation sample project (http://www.pdftron.com/net/
samplecode.html#Annotation) is a good start. There are methods to
extract links (annot.GetLinkAction()), to obtain positioning
information (annot.GetBBox()), etc.
