I need to make a watermark in a PDF File, like a Ex Libris ...

I Need to open a PDF file and, page by page, mix another image in the page like watermark.

I can to do it in .JPG file using Mask ( imagejpg.Canvas.CopyMode := cmSrcPaint )

Well, I need to get a .PDF file and transform it, page by page in JPEG ( page1.jpg , page2.jpg, page3.jpg, ... ) and remount the PDF from the .jpg files ( page1.jpg , page2.jpg, page3.jpg, ... ) .

Anyone know the 'route' ?

Thanks
