localTransform

localTransform: Matrix

The local transformation matrix.

pivot

pivot: ObservablePoint<any>

The pivot point of the displayObject that it rotates around.

position

position: ObservablePoint<any>

The coordinate of the object relative to the local coordinates of the parent.

scale

scale: ObservablePoint<any>

The scale factor of the object.

skew

skew: ObservablePoint<any>

The skew amount, on the x and y axis.

worldTransform

worldTransform: Matrix
