Hi Leonard, Thanks for your reply.
I might have been a bit vague in my original email. Sorry about that. My collaborator had a better example to explain: " suppose you print a PDF onto a sheet of paper. Now print a second PDF on the same sheet of paper. " That's the functionality I was trying to describe last time. Right now, we're stripping all the strokes off the second PDF and adding them back onto the first, but it's forcing us to use the mangled poppler implementation. Here are the PDFs we are trying to superimpose. 2011-04-24-Note-14-48.pdf and 2011-04-24-Note-14-49.pdf are the source images. out_merge.pdf is the podofoimpose result 2011-04-24-Note-14-48.xoj.pdf is what we are hoping to get. (yes, we're working on the xournal project =) ) We plan to call the podofo libs to integrate it into our project. It's ok if podofoimpose doesn't have the functionality, as long as the libs do.
