Library has wrappers to all the basic views and they all extend either PDPView directly or some other subclass of PDFView.
PDFView or any of its implementation, has some of the basic methods overridden from its native View setPadding() , setBackgroundColor() and setLayout() but for some reason you need any other internal method such as setRotationX() or setRotationY() you can use it directly by calling getView().setRotationX()
