PDF reader with page curling effect and zoom function

Question

I want to make a PDF reader with page curling effect AND zooming. I searched a lot and found this Zoom support while page curling effect present in pdf reader app solution for an pdf reader with a page curling effect and zoom function. But how do I combine "Leaves Source Code" and "Zooming PDF Viewer Source Code"? Do you have a solution or a Source Code for this?
