# Create a drawing canvas

# Draw few lines
canvas.SetPen(blackStrokeAndFillPen)
canvas.DrawText(10, 10, "Red 2 pixels thick line")
canvas.SetPen(redThinPen)
canvas.DrawLine(10, 15, 100, 15)

canvas.SetPen(blackStrokeAndFillPen)
canvas.DrawText(10, 35, "Blue 5 pixels thick line")
canvas.SetPen(blueThickPen)
canvas.DrawLine(10, 40, 100, 40)

# Draw Rectangle
canvas.SetPen(blackStrokeAndFillPen)
canvas.DrawText(10, 60, "Filled Rectangle")
canvas.SetPen(lightGreenStrokeYelloFillPen)
canvas.DrawRectangle(10, 65, 40, 40)

# Draw Circle and Ellipse
canvas.SetPen(blackStrokeAndFillPen)
canvas.DrawText(10, 120, "Circle and Ellipse")
canvas.SetPen(redThinPen)
canvas.DrawCircle(40, 160, 30)
canvas.SetPen(redThinPen)
canvas.DrawEllipse(100, 160, 20, 10)

# Draw Polyline
canvas.SetPen(blackStrokeAndFillPen)
canvas.DrawText(10, 220, "Polyline")
canvas.SetPen(redThinPen)
canvas.DrawPolyline([[10, 230], [15, 240], [20, 250], [30, 235], [40, 270]])

# Draw Polygon
canvas.SetPen(blackStrokeAndFillPen)
canvas.DrawText(160, 30, "Polygon")
canvas.SetPen(purpleStrokeGreenFillPen)
canvas.DrawPolygon([[220, 10], [300, 210], [170, 250], [123, 234]])
