GdiGraphics.DrawEllipse Method (Pen, Int32, Int32, Int32, Int32)

Draws an ellipse.

Namespace: Aurigma.GraphicsMill.Drawing
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)


Visual Basic
Public Sub DrawEllipse ( _
	pen As Pen, _
	x As Integer, _
	y As Integer, _
	width As Integer, _
	height As Integer _
public void DrawEllipse(
	Pen pen,
	int x,
	int y,
	int width,
	int height



Type: Aurigma.GraphicsMill.Drawing.Pen

Pen object which is used to outline an ellipse.

Type: System.Int32

X-coordinate of the top left corner of the bounding rectangle for the ellipse.

Type: System.Int32

Y-coordinate of the top left corner of the bounding rectangle for the ellipse.

Type: System.Int32

Width of the bounding rectangle for the ellipse.

Type: System.Int32

Height of the bounding rectangle for the ellipse.


Ellipse is defined by its tightest bounding rectangle. If you have an ellipse defined with central point and two radiuses, you can convert these parameters to rectangle in the following way:

// Let's assume we have centerX, centerY - coordinates of the ellipse center, 
// horizontalRadius and verticalRadius - radiuses of the ellipse.
// We are calculating rectX, rectY, rectWidth, and rectHeight which specify 
// bounding rectangle for ellipse.

rectX = centerX - horizontalRadius;
rectY = centerY - verticalRadius;
rectWidth = horizontalRadius * 2;
rectHeight = verticalRadius * 2;

All the coordinates are measured in units specified with Unit property.

To fill an ellipse, use FillEllipse(Brush, Int32, Int32, Int32, Int32) method.

System.Drawing.Pen pen = new System.Drawing.Pen(

graphics.DrawEllipse(pen, 10, 5, 80, 50);
