Hi,
I am a bit confused about the options I'd have to purchase to do the following:

-use the GdViewer for displaying pdf files (incl. searching)
-use the thumbnail control for displaying thumbs from pdf

What do I need to buy?

We have a requirement where we have to filter the list of thumbs based on certain bookmarks the pdf pages have.
With the click of a button, we only want to show favorite pages the user has marked with a bookmark.
Is this even possible?
