# Pdf watermark

This module was written to add watermarks (backgrounds) to PDF reports. Because of the way wkhtmltopdf handles headers and footers in the current versions, it is quite impossible to have a background for the complete page using HTML and CSS. That is why this module inserts the image at the PDF level.
