IMagic object creation shows error?

I just try to integrate ImageMagick开发者_如何学JAVA into my PHP project. I installed and just execute the sample files that they provided with the imagick-3.0.0RC1 zip file. But it shows

Fatal error: Class 'Imagick' not found in C:\wamp\www\imagick-3.0.0RC1\imagick-3.0.0RC1\examples\watermark.php on line 9

this kind of an error how can I avoid that. I cant see any class including section on that page. How to include the class files.

You need to install the ImageMagick PHP extension. According to the manual there is no prebuilt extension for Windows so you'll probably have to configure and compile it yourself.
