Parameters

startX: Type: System Double
X-coordinate of the start point of the arc.

startY: Type: System Double
Y-coordinate of the start point of the arc.

midX: Type: System Double
X-coordinate of the midpoint of the arc.

midY: Type: System Double
Y-coordinate of the midpoint of the arc.

endX: Type: System Double
X-coordinate of the end point of the arc.

endY: Type: System Double
Y-coordinate of the end point of the arc.

ellipseFraction: Type: System Double
The fraction of the ellipse that passes through the start, mid-, and end points. This value must be > 0 and < 1.

Exceptions
