I am trying to extract bookmarks from existing pdf doc. The pdf doc could have no bookmarks, if so, ExtractBookmarks function throws exception "System.NullReferenceException" with normal error message: "Object reference not set to an instance of an object.".

My code is pretty simple:
PdfBookmarkEditor pdfBookmarkEditor = new PdfBookmarkEditor();
pdfBookmarkEditor.BindPdf(fullFileName);
Bookmarks bms = new Bookmarks();
bms = pdfBookmarkEditor.ExtractBookmarks();
Anyone has idea about it?

I am running into this problem too. Is there a timeframe for a resolution? Is there a work around - for instance is there away of checking if a document has any bookmarks before calling this function?
thanks!
Ken
