Adds the content of a PDF file to the foreground of the document with optional opacity.
Please ensure the watermark PDF file has proper transparency, all non-transparent areas will get rendered as watermark. This might include white areas which aren’t visibly distinguishable from the background. You can use PDF Architect to create a watermark PDF or to modify an existing PDF accordingly.
Opacity: The opacity of the watermark document.
In case the watermark file has less pages than the actual document you can select a Repetition:
No Repetition: The first watermark pages will be set (first background page on the first document page, second to second etc.). Page numbers above the number of watermark pages do not get a watermark.
Repeat all pages: The watermark pages repeat themselves until the end of the document. This can be used to have different watermarks for even and odd pages.
Repeat last page: The first watermark pages will be set. The last watermark page will be repeated until the end of the document. This is useful if the first page has a different layout than the rest of the pages (i.e. cover page and content pages).
Fit to page: Automatically scale the watermark to fit the page.
