Example

Here we draw a line.

[C#] 

XPoint[] points = new XPoint[] { 
  new XPoint(30, 190), 
  new XPoint(100, 10), 
  new XPoint(170, 190), 
  new XPoint(10, 70), 
  new XPoint(190, 70)};
Canvas canvas = new Canvas(300, 300, new XColor(Color.Yellow));
DrawOptions drawOpts = new DrawOptions(canvas);
drawOpts.PenColor = new XColor(Color.Blue);
canvas.DrawLine(points, drawOpts);
canvas.SaveAs(Server.MapPath("Canvas_DrawLine_91.png"));

[Visual Basic] 

Dim points As XPoint() = New XPoint() {New XPoint(30, 190), New XPoint(100, 10), New XPoint(170, 190), New XPoint(10, 70), New XPoint(190, 70)}
Dim canvas As New Canvas(300, 300, New XColor(Color.Yellow))
Dim drawOpts As New DrawOptions(canvas)
drawOpts.PenColor = New XColor(Color.Blue)
canvas.DrawLine(points, drawOpts)
canvas.SaveAs(Server.MapPath("Canvas_DrawLine_91.png"))
