The ManipulationDelta structure has these fields.

FieldData typeDescription
Expansion | expansion

Number [JavaScript] | System.Single [.NET] | float32 [C++]

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 | rotation

Number [JavaScript] | System.Single [.NET] | float32 [C++]

The change in angle of rotation, in degrees.

Scale | scale

Number [JavaScript] | System.Single [.NET] | float32 [C++]

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 1.0.

Translation | translation

Point

The change in x-y screen coordinates, in DIPs.
