Apply an image watermark to a PDF

POST https://api.pdfrest.com/watermarked-pdf

This request demonstrates how to apply a file watermark to a PDF. This kind of watermark uses another PDF (using either watermark_file or watermark_file_id as a form-data parameter) and applies it as a watermark to the primary input document (file or id).

Horizontal and vertical offsets of the watermark are measured in PDF units. (1 inch = 72 PDF units)
