I am still trying to get this to work. I tried switching to iText library and while initially getting better results with annotations, it still did not work. I am coming to the conclusion that the primary issue is that if I copy an annotation from one document to another the problem is that the annotation dictionary is a shallow copy. The annotation dictionary references other objects that are not copied to the destination document. So I am wondering if there is a simple way given a dictionary to do a deep copy to another document?
