/*
 * Repeated contents:
 * Create contents which are used identically on multiple pages, such as fixed
 * headers or footers.
 * 
 * Create a PDFlib template (which will result in a PDF Form XObject) for
 * a business letter header which holds an image and some text. Then place
 * the template. When placing the template on multiple pages (or multiply on
 * the same page), the actual PDF operators for constructing the template are
 * only included once in the PDF file, thereby saving PDF output file size. 
 * 
 * Required software: PDFlib/PDFlib+PDI/PPS 10
 * Required data: image file
