pdfx/starter_pdfx5g

 *

 * PDF/X-5g starter:

 * Create PDF/X-5g conforming output with a reference to an external page

 *

 * The external document from which a page is referenced must conform to

 * one of the following standards:

 * PDF/X-1a:2003, PDF/X-3:2002, PDF/X-4, PDF/X-4p, PDF/X-5g, or PDF/X-5pg

 *

 * In order to properly display and print the referenced target page with

 * Acrobat you must configure Acrobat appropriately (see PDFlib Tutorial),

 * and the target PDF must be available to Acrobat.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 8

 * Required data: font file, external PDF/X target, ICC output intent profile

 *                (see www.pdflib.com for ICC profiles)
