    Protected_currentLocalID

    _currentLocalID: number

    The locally unique ID of the local transform used to calculate the current local transformation matrix.

    Protected_cx

    _cx: number

    The X-coordinate value of the normalized local X axis, the first column of the local transformation matrix without a scale.

    Protected_cy

    _cy: number

    The X-coordinate value of the normalized local Y axis, the second column of the local transformation matrix without a scale.

    Protected_localID

    _localID: number

    The locally unique ID of the local transform.

    _parentID

    _parentID: number

    The locally unique ID of the parent's world transform used to calculate the current world transformation matrix.

    Protected_rotation

    _rotation: number

    The rotation amount.

    Protected_sx

    _sx: number

    The Y-coordinate value of the normalized local X axis, the first column of the local transformation matrix without a scale.

    _worldID

    _worldID: number

    The locally unique ID of the world transform.

    localTransform: Matrix

    The local transformation matrix.

    pivot: ObservablePoint

    The pivot point of the displayObject that it rotates around.

    position: ObservablePoint

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

    scale: ObservablePoint

    The scale factor of the object.

    skew: ObservablePoint

    The skew amount, on the x and y axis.

    worldTransform: Matrix

    The world transformation matrix.

    IDENTITY: Transform

    A default (identity) transform.
