Hi, I need to modify on the fly PDF file that are stored in a ZODB. The basic idea is to use these PDF files as templates and add to them some texts and drawings generated by some external method or with DTML scripts. I tried Pavlos ZpdfDocument product. It's very nice to generate PDF code from HTML or Structured text. However I need something more flexible. I took a look also at the PDFGen library. I think it could meet some of my requirements, especially the Canvas methods are very useful and easy. But here too it seems that you can only produce new PDF documents. As anyone tried to do the same thing (adding objects to PDF files)? Any pointer greatly appreciated. ****************************************************** Oscar Picasso picasso@videotron.ca ******************************************************
