Spire.PDF for compare

[mbanks]

I have a project requirement to compare pdf files and list the changes (non-GUI). We create templates which are sent to our print shop and merged with data files that are sent. What we are attempting to do is write code that will compare our template to a sample pdf sent back from our printer and verify that the only changes in the sample doc are the merged data fields which should be returned as a list. Would Spire.PDF be a good fit for this and if so, are there any existing examples that could be referenced?
