Thanks for the info. I guess OCGs can not be created with PdfStamper? I can
call all the methods but no layers get created. So I assume that layers can
only go into a new doc using PdfWriter? If I could create the layered
content with PdfStamper, my problem would be solved.
Regarding reading/reproducing the links from the pdf to be concated to my
layered map doc, can someone point the way to how to do that? Not being an
iText or pdf expert, I am having some trouble figuring out where to look.
Thanks,
Eliot Cline

The only way to do it is to use PdfStamper for the OCG pdf and import and
add the other pages recreating the links. This also means that you must
read the links to be able to reproduce them.

Subject: [iText-questions] PdfCopy and Layers
Hello,
I have just started using iText (.NET version). I am having a problem that
hopefully someone can help me with. We are using iText to extract spatial
data from PostgreSQL database and render detailed maps in pdf. So far
eveything has worked very well but I am totally stumped now. The maps are
rendered in layers (OCG) and an index of city names is appended to the end
of the document. There is some other content in a single, multi-page pdf
file that gets appended to the pdf file containing the map. The content in
this file has many hyperlinks to websites and internal links to other
pages.
If I use PdfCopy the resulting merged file contains all hyperlinks and
anchors, but the OCGs are gone. Tried to use PdfStamper to add the
additional pdf file to the map doc. The OGCs are intact in this case but
all the hyperlinking is removed from the appended content. Is there some
way to keep both links and OGCs in my final merged document? If this
question doesn't have an obvious answere, I would be happy to post my
code.
Thanks,
Eliot Cline
