Appends a line to the current path.
The line is defined by the end point of the path and a point that depends on the specified parameter. The Y parameter specifies the distance to the end point of the current path on the y-axis. VLineToRel adds the end point of the line to the Points array. The end point of the line is moved vertically by a distance equal to Y to the end point of the path. The added point is of type LineTo. To move the start point of the line, call MoveTo or MoveToRel before calling VLineToRel.
To find the end point of the path, call the
LastPoint method.

The function returns the current path so that you can chain together commands, e.g., aPath.MoveTo(PointF(50,50)).LineTo(PointF(100,100).AddPolygon(Polygon1).AddEllipse(RectF(10,10,200,100)); |
