Pan- Zoom- and RotateGesture

In this example we use PanGesture, ZoomGesture and RotateGesture to allow direct manipulation of an element's 2D transformation. All of these gestures require an InteractiveTransform, which is passed through the Target parameter. This InteractiveTransform is what actually transforms its parent element in response to the movement interpreted by Pan- Zoom- and RotateGesture.

We've also included a Shadow whose parameters are controlled by UX Expressions to give the illusion of depth.

Note: Some of the gestures in this example requires multi-touch, and thus won't be usable from local preview. Please run the example on a device.
