Draws an ellipse defined by a bounding rectangle specified by coordinates for the upper-left corner of the rectangle, a height, and a width.

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

'Declaration
Public Sub DrawEllipse ( _
	pen As Pen, _
	x As Integer, _
	y As Integer, _
	width As Integer, _
	height As Integer _
)

Parameters

pen
Type: System.Drawing.Pen

Pen that determines the color, width, and style of the ellipse.

x
Type: System.Int32

The x-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse.

y
Type: System.Int32

The y-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse.

width
Type: System.Int32

Width of the bounding rectangle that defines the ellipse.

height
Type: System.Int32

Height of the bounding rectangle that defines the ellipse.

ExceptionCondition
ArgumentNullException

pen is Nothing.

This method draws an ellipse that is defined by the bounding rectangle described by the x, y, width, and height parameters.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a black pen.

  • Creates the position and size of a rectangle to bound an ellipse.

  • Draws the ellipse to the screen.

Private Sub DrawEllipseInt(ByVal e As PaintEventArgs)

    ' Create pen. 
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create location and size of ellipse. 
    Dim x As Integer = 0
    Dim y As Integer = 0
    Dim width As Integer = 200
    Dim height As Integer = 100

    ' Draw ellipse to screen.
    e.Graphics.DrawEllipse(blackPen, x, y, width, height)
End Sub
