Is it possible to create a behavior for Pinch and zoom to Image control in windows phone 8. I am trying to apply pinch and zoom along with rotation to Image in my application. In a forum I found that Gesture listener is deprecated and they are not promoting implementation with gesture. So can any one please suggest an alternative method for me.
If you're targeting only Windows Phone 8 you can use the new ManipulationDeltaEventArgs.PinchManipulation property from the ManipulationDelta event. Instead of using GestureListener/TouchPanel for pinch & zoom you should rely on this new property.
Maybe this could help you https://multitouch.codeplex.com/
