怎样使用PDFBox中的PDFToImage？急啊

[熊爸爸的爸爸]

本人一新手，初次在Netbeans6.5中使用PDFBox
在PDFBox的官网上看到它的特性里有这么一条：“Create images from PDF pages”，看了http://incubator.apache.org/pdfbox/commandlineutilities/PDFToImage.html一点都没弄清楚应该怎样使用这一特性

请各位高手帮帮忙，小弟现在很急！
万分感谢！

直接向classpath种设定PDFBox的lib就可以了。

谢谢这位大哥，已经添加了lib

小弟只是不知道用什么样的代码实现这一功能

楼上的我的pdfbox怎么没有PDFImageWriter这个类啊

[wuda00001]

pdfbox0.8以后的版本(包含0.8)才有PDFImageWriter这个类，以前版本是不包含这个类的
