What you could do is embed each page of the original PDF as a PDFormXObject, which is similar to an <iframe> in HTML, if you’re familiar with that. Then you can position the Form XObject where you wish on the page, and set its scaling and crop box. — John > -------- Original message -------- > From: Sumit Mohan Jha <[email protected]> > Date: 01/29/2016 12:30 PM (GMT-06:00) > To: [email protected] > Subject: Further questions related to PDFBOX-3216 Issue > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
