Zoom support while page curling effect present in pdf reader app

问题

Hi I am developing an ipad Magazine app where I need to display pdf files.I am using leaves project for page curl effect.This works great. But in landscape page fits to height(768px) and it becomes difficult to read the font. Thats why I want to support zoom in/out on this view.
I am a newbie to Core Graphics.I think in leaves project they parse pdf to show image of each page.But I dont know why zoom is not supported if it is an image. There are some more branches of leaves project for implementing this feature but all of them are not perfect.
Shall I continue using leaves or UIViewAnimationTransitionCurlUp/Down will help me for both the problems?
Thanks
