widthRead only
double (float)
The width (magnitude on the X axis), in CSS pixels, of the contact geometry of the pointer.
heightRead only
double (float)

tiltYRead only
long (float)
The plane angle (in degrees, in the range of -90 to 90) between the X-Z plane and the plane containing both the transducer (e.g. pen stylus) axis and the X axis.
