Error in wacom pressure level

Question

Hi,
i am using the following code to measure the wacom (intuos4 with stylus) pressure level.

        public double getPressure(StylusEventArgs e)
        {
            return e.GetStylusPoints(window)[e.GetStylusPoints(window).Count - 1].GetPropertyValue(StylusPointProperties.NormalPressure);
        }

  according to the wacom manual, i should get value range of 0-1023. but right now it returns a range 0-32767

can anyone help me to solve the problem.
