  • Creates a rectangle that bounds an ellipse.

  • Fills the ellipse on the screen.

Public Sub FillEllipseRectangleF(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim redBrush As New SolidBrush(Color.Red)

    ' Create rectangle for ellipse.
    Dim x As Single = 0.0F
    Dim y As Single = 0.0F
    Dim width As Single = 200.0F
    Dim height As Single = 100.0F
    Dim rect As New RectangleF(x, y, width, height)

    ' Fill ellipse on screen.
    e.Graphics.FillEllipse(redBrush, rect)
