Definition

Returns the orientation of the touch area and tool area in radians clockwise from vertical for the given pointer <em>index</em> (use #getPointerId(int) to find the pointer identifier for this index).

[Android.Runtime.Register("getOrientation", "(I)F", "")]
public float GetOrientation (int pointerIndex);
[<Android.Runtime.Register("getOrientation", "(I)F", "")>]

Returns

Attributes

Remarks

Returns the orientation of the touch area and tool area in radians clockwise from vertical for the given pointer <em>index</em> (use #getPointerId(int) to find the pointer identifier for this index). An angle of 0 radians indicates that the major axis of contact is oriented upwards, is perfectly circular or is of unknown orientation. A positive angle indicates that the major axis of contact is oriented to the right. A negative angle indicates that the major axis of contact is oriented to the left. The full range is from -PI/2 radians (finger pointing fully left) to PI/2 radians (finger pointing fully right).
