Methods

DrawArc(Pen, Single, Single, Single, Single, Single, Single)

Draws an arc representing a portion of an ellipse specified by a pair of coordinates, a width, and a height.

Declaration

System.Single	width	Width of the rectangle that defines the ellipse.
System.Single	height	Height of the rectangle that defines the ellipse.
System.Single	startAngle	Angle in degrees measured clockwise from the x-axis to the starting point of the arc.
System.Single	sweepAngle	Angle in degrees measured clockwise from the startAngle parameter to ending point of the arc.
