Sample Implementation

C#

	public RadForm1()
	{
		InitializeComponent();
		this.radImageEditor1.LoadAsync("../../London_01.jpg");
		this.radImageEditor1.ImageLoaded += radImageEditor1_ImageLoaded;
	}
	private void radButton1_Click(object sender, EventArgs e)
	{
		GraphicsPath path = new GraphicsPath();
		path.AddLine(20, 20, 200, 20);
		path.AddLine(20, 20, 20, 200);
		path.AddEllipse(new Rectangle(30, 30, 40, 40));
		radImageEditor1.ImageEditorElement.DrawShape(path, Color.Red, Color.Green, 3);
		radImageEditor1.ImageEditorElement.SaveState();
	}
	

VB.NET

	Class SurroundingClass
    Public Sub New()
        InitializeComponent()
        Me.radImageEditor1.LoadAsync("../../London_01.jpg")

    End Sub

    Private Sub radButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim path As GraphicsPath = New GraphicsPath()
        path.AddLine(20, 20, 200, 20)
        path.AddLine(20, 20, 20, 200)
        path.AddEllipse(New Rectangle(30, 30, 40, 40))
