Fields

Expansion

The change in distance between touch contacts, as device-independent pixel (DIP). 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 Expansion would be 100.0.
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 pixel (DIP).
