I m using Dompdf to convert Html Page to PDF. As client's requirement pdf should have watermark image at background of document. I have tried many ways in coding and also differnt css style but its not helpful. Is anybody has any idea about it? please Help me out.
Which version of DOMPDF? With the 0.6.0 release you could use a fixed-position element to act as a watermark. Here's a document shell:
<html>
<head>
<style>
#watermark { position: fixed; bottom: 0px; right: 0px; width: 200px; height: 200px; opacity: .1; }
</style>
</head>
<body>
<div id="watermark"><img src="http://code.google.com/p/dompdf/logo" height="100%" width="100%"></div>
</body>
</html>

On 0.5.1 you could use the background-image style declaration on the body. You have less control over the styling, so you'll want to make sure the image is formatted exactly how it should appear in the document, specifically related to size and opacity. There are other issues, as well, but this does work. Here's a document shell:
<html>
<head>
<style>
body { background-image: url(http://www.wolfsrainfans.com/wp-content/uploads/2011/04/Wolfs_Rain__Taboe_by_Nizira_Hathor.png); background-position: bottom right; background-repeat: no-repeat; }
</style>
</head>
<body>
</body>
</html>
