What it does
This transform adds a watermark to PDF content.
You can use this while generating PDF, perhaps after the Text to PDF transform or PCL to PDF. Or you can also use this as the only transform, perhaps adding a watermark to a PDF created some other way in RPM, or perhaps sent as the print job
RPM includes an Image Overlay manager which maintains a list of overlays. These overlays include the image file, where on the page the image will appear, which page, and more.
In the PDF Watermark dialog, you select which of your predefined overlays you want to be included.
