Instance Method

curve(to:controlPoint1:controlPoint2:)

Adds a Bezier cubic curve to the receiver’s path.

Declaration

func curve(to endPoint: NSPoint, controlPoint1: NSPoint, controlPoint2: NSPoint)

Parameters

aPoint

The destination point of the curve segment, specified in the current coordinate system

controlPoint1

The point that determines the shape of the curve near the current point.

controlPoint2

The point that determines the shape of the curve near the destination point.

Discussion

You must set the path's current point (using the move(to:) method or through the creation of a preceding line or curve segment) before you invoke this method. If the path is empty, this method raises an genericException exception.
