Graphics.DrawPie Method (Pen, RectangleF, Single, Single)
Draws a pie shape defined by an ellipse specified by a RectangleF structure and two radial lines.
Assembly: System.Drawing (in System.Drawing.dll)
Public Sub DrawPie ( pen As Pen, rect As RectangleF, startAngle As Single, sweepAngle As Single )
RectangleF structure that represents the bounding rectangle that defines the ellipse from which the pie shape comes.
Angle measured in degrees clockwise from the x-axis to the first side of the pie shape.
Angle measured in degrees clockwise from the startAngle parameter to the second side of the pie shape.
This method draws a pie shape defined by an arc of an ellipse and the two radial lines that intersect with the endpoints of the arc. The ellipse is defined by the bounding rectangle. The pie shape consists of the two radial lines defined by the startAngle and sweepAngle parameters, and the arc between the intersections of those radial lines with the ellipse.
If the sweepAngle parameter is greater than 360 degrees or less than -360 degrees, it is treated as if it were 360 degrees or -360 degrees, respectively.
Creates a black pen.
Creates a rectangle that bounds a complete ellipse.
Defines the angles at which to start drawing (relative to the x axis) and through which to draw (both in a clockwise direction).
Draws the pie segment to the screen.
