Fields

Expansion	The change in x-y screen coordinates, in device-independent pixels (DIP).
Rotation	The change in angle of rotation, in degrees.
Scale	The change in distance between touch contacts, as a percentage. For example, if the distance between two contacts changes from 100 device-independent pixel (DIP) to 200 device-independent pixel (DIP) during a manipulation, the value of Scale would be 2.0.
Translation	The change in x-y screen coordinates, in device-independent pixels (DIP).
