GraphicsPath.AddArc Method (RectangleF, Single, Single)

 

Appends an elliptical arc to the current figure.

Namespace:   System.Drawing.Drawing2D
Assembly:  System.Drawing (in System.Drawing.dll)

Public Sub AddArc (
	rect As RectangleF,
	startAngle As Single,
	sweepAngle As Single
)

Parameters

rect
Type: System.Drawing.RectangleF

A RectangleF that represents the rectangular bounds of the ellipse from which the arc is taken.

startAngle
Type: System.Single

The starting angle of the arc, measured in degrees clockwise from the x-axis.

sweepAngle
Type: System.Single

The angle between startAngle and the end of the arc.

If there are previous lines or curves in the figure, a line is added to connect the endpoint of the previous segment to the beginning of the arc.

The arc is traced along the perimeter of the ellipse bounded by the specified rectangle. The starting point of the arc is determined by measuring clockwise from the x-axis of the ellipse (at the 0-degree angle) by the number of degrees in the start angle. The endpoint is similarly located by measuring clockwise from the starting point by the number of degrees in the sweep angle. If the sweep angle is greater than 360 degrees or less than -360 degrees, the arc is swept by exactly 360 degrees or -360 degrees, respectively.
