I'm attempting to merge multiple pdf documents into a single pdf file using PDF::API2.

The problem I'm having is importing PDF 1.3 docs into an existing PDF::API2 object using the importpage method. Since PDF::API2 creates new pdf docs as PDF 1.4, the imported PDF 1.3 pages are appearing blank.

If I open a 1.3 doc as a PDF::API2 object, are there some parameters I can update in the object that will allow me to view the page once it's imported to another pdf object?

Thanks
