general/repeated_contents

 * 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 Lite/PDFlib/PDFlib+PDI/PPS 7

 * Required data: image file
