PDFLib

From http://www.pdflib.com/pdflib/faq.html: "This demo stamp appears when one of our binaries distributed by PDFlib GmbH is used. It can be disabled by purchasing a PDFlib license, and applying the delivered license key (serial) at runtime with the PDF_set_parameter() function as indicated in the manual. With the ActiveX/COM edition of PDFlib the serial can also be supplied during the installation process." I have a license key, now what parameters do I pass PDF_set_parameter()? The PHP man doesn't say, nor does the PDFLib man (so far as I can tell). Any help would be greatly appreciated- I'm getting pretty frustrated.
