推荐答案
哪个版本的DOMPDF？使用0.6.0版本，您可以使用固定位置元素作为水印。这是一个文档外壳：
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>
请参阅此处的示例：
开0.5.1你可以在主体上使用背景图像风格声明。您对样式的控制较少，因此您需要确保图像的格式与文档中的显示格式完全相同，具体涉及大小和不透明度。还有其他一些问题，但这确实奏效。这是一个文档外壳：
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>
