Examples

The following example demonstrates how to create a StylusPoint.

StylusPointDescription newDescription =
      new StylusPointDescription(new StylusPointPropertyInfo[]
                    {
                        new StylusPointPropertyInfo(StylusPointProperties.X),
                        new StylusPointPropertyInfo(StylusPointProperties.Y),
                        new StylusPointPropertyInfo(StylusPointProperties.NormalPressure),
                        new StylusPointPropertyInfo(StylusPointProperties.XTiltOrientation),
                        new StylusPointPropertyInfo(StylusPointProperties.YTiltOrientation),
                        new StylusPointPropertyInfo(StylusPointProperties.BarrelButton)
                    });

int[] propertyValues = { 1800, 1000, 1 };

StylusPoint newStylusPoint = new StylusPoint(100, 100, .5f, newDescription, propertyValues);

Dim newDescription As New StylusPointDescription( _
    New StylusPointPropertyInfo() {New StylusPointPropertyInfo(StylusPointProperties.X), _
                                   New StylusPointPropertyInfo(StylusPointProperties.Y), _

                                   New StylusPointPropertyInfo(StylusPointProperties.YTiltOrientation), _
                                   New StylusPointPropertyInfo(StylusPointProperties.BarrelButton)})

Dim propertyValues As Integer() = {1800, 1000, 1}

Dim newStylusPoint As New StylusPoint(100, 100, 0.5F, newDescription, propertyValues)

Remarks

pressureFactor must have a value between 0 and 1, inclusive. A value of 0 indicates that no pressure is applied, while a value of 1 indicates that the maximum amount of pressure is applied. A value of 0.5 indicates that 50% of the maximum pressure is applied, and so on.
