Los puntos del lápiz óptico que se recopilan del lápiz óptico.

Ejemplos

En el ejemplo siguiente se muestra cómo cambiar los puntos del lápiz óptico en el OnStylusDown método . Para crear un StylusPlugIn que restrinja la entrada de lápiz a un área determinada, consulte la StylusPlugIn información general.

    base.OnStylusDown(rawStylusInput);

    // Get the StylusPoints that have come in
    StylusPointCollection stylusPoints = rawStylusInput.GetStylusPoints();

    // Modify the (X,Y) data to move the points 
    // inside the acceptable input area, if necessary
