There's more than one way to do this, but every solution has its downside. 1. You could create a new Document and PdfWriter to produce a PDF file with the desired page size. Then create a PdfReader that reads the existing PDF file. Ask the PdfReader for the number of pages and get every page as a PdfImportedPage in a loop. Wrap the PdfImportedPage in an Image object, scale (shrink) the image object, and add it to the new document with the desired offset, along with the extra content above or under the image. Downside: PdfImportedPage works like a photocopy machine: it copies the content (as it would appear on paper), but it doesn't copy the interactive features (hyperlinks, form fields,...). If you have such features in your PDF, you will have to do a lot of extra work retrieving them from the original document, transforming the coordinates and adding the features to the new document. 2. How important is the actual page size to you? If you don't mind Adobe reader to resize the document, then you may keep the content as is, but change the page boundaries. In this case, you'll need PdfReader and PdfStamper. With PdfReader, you'll loop over all the pages and change the page boundaries; then with PdfStamper, you add the new content so that it's outside the original boundaries, but inside the new ones. Downside: the PDF document won't have a standard page size anymore. I'm not sure if there's a way to work around this. br, Bruno ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
