我不认为有将是Android上的一个简单的方法，为您解析BinaryData是在PowerPoint XML文件present。

I don't think there is going to be an easy way on Android for you to parse the BinaryData that is present in a powerpoint XML file.

我想你会更好保存幻灯片页图像，这样你已经有他们在的东西，很容易使成位图对象，并编辑，如你所愿。

I think you'd be better off saving your pp slides as images, that way you already have them in something that is easy to make into a Bitmap object and edit as you wish.
