Returns the rotation angle, in degrees, of the contact area ellipse defined by
Touch.radiusY. The value may be between 0 and 90. Together, these three values describe an ellipse that approximates the size and shape of the area of contact between the user and the screen. This may be a large ellipse representing the contact between a fingertip and the screen or a small one representing the tip of a stylus, for example.
var angle = touchItem.rotationAngle;
- The number of degrees of rotation to apply to the described ellipse to align with the contact area between the user and the touch surface.
