Gets the rectangular area that is reported as the touch-point contact area.

Namespace:  System.Windows.Input

public Size Size { get; }

Property Value

Type: System.Windows.Size
A Size value. If the device that is used for touch input does not support reporting a touch size area, this property reports a Size with values of -1, instead of null.

Some devices do not support reporting a contact area size and will not set the TOUCHEVENTMASKF_CONTACTAREA flag in the WM_TOUCH message that is used in the platform code. In that case, this property returns a Size value that shows a Height and Width both equal to -1.
