您必须看看这个开源项目为相同的需求，这可以帮助你做更多的事也。

You need to have look at this open-source for project for the same requirement, that can be helpful to you to do many more things also.

项目：PdfRenderer

有一个名为Java类PDFPage.java在 pdfview 包。这个类有一个方法来获取页面的图像。

There is one Java class named PDFPage.java in pdfview package. that class have a method to get Image of the page.

我也实施在我的测试项目同样的事情，在java code是 在这里为你 。我已创建了一个方法 SHOWPAGE ，它接受的页面没有和缩放级别并返回该页面位图。

I have also implemented the same thing in my test project and the java code is here for you. I have created one method showPage which accepts the page no and zoom level and return that page as Bitmap.

希望这可以帮助你。你只需要获得项目或JAR的是，阅读详细记录JavaDoc以相同的，然后尝试，像我一样实现相同的。

Hope this can help you. You just need to get that Project or JAR for that, Read the well-documented JAVADOC for the same and then try and implement the same as I did.
