How to Use FillMode to Fill the Interior of a Path

The following example creates a path that has one open figure (an arc) and one closed figure (an ellipse). The FillPath method fills the path according to the default fill mode, which is Alternate. Note that the path is filled (according to Alternate) as if the open figure were closed by a straight line from its ending point to its starting point.

Dim path As New GraphicsPath()

' Add an open figure.
path.AddArc(0, 0, 150, 120, 30, 120)

' Add an intrinsically closed figure.
path.AddEllipse(50, 50, 50, 100)

Dim pen As New Pen(Color.FromArgb(128, 0, 0, 255), 5)
Dim brush As New SolidBrush(Color.Red)

' The fill mode is FillMode.Alternate by default.
e.Graphics.FillPath(brush, path)
e.Graphics.DrawPath(pen, path)
