Public Property ViewportVerticalShift As System.Single
public System.float ViewportVerticalShift {get; set;}
Remarks
Specifies the degree of vertical view translation from a full view. Translation is relative to a normalized box with origin in the bottom left corner. Translation of more than a full unit (more than 1.0 or -1.0) causes the view to translate “out of view” when ViewPortScale=1.
