| Name | Description | |
|---|---|---|
 | Expansion | The change in distance between touch contacts, as DIPs. For example, if the distance between two contacts changes from 100 DIPs to 200 DIPs 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 DIPs to 200 DIPs during a manipulation, the value of Scale would be 2.0. |
| Translation | The change in x-y screen coordinates, in DIPs. |
