You might want to take a look at chapter 14.11.2 "Page Boundaries" in the PDF specification, which discusses the layout box model. Perhaps it would suffice if you simply resize the MediaBox, and/or define CropBox. PDFBox provides you a nice API for that (eg. org.apache.pdfbox.pdmodel.PDPage#setMediaBox(PDRectangle)). VR
