element(at:associatedPoints:)
Gets the element type and (and optionally) the associated points for the path element at the specified index.
Declaration
func element(at index: Int, associatedPoints points: NSPointArray?) -> NSBezierPath.ElementTypeParameters
- index:
The index of the desired path element.
- points:
On input, a C-style array containing up to three
NSPointdata types, orNULLif you do not want the points. On output, the data points associated with the specified path element.
Return Value
The type of the path element. For a list of constants, see NSBezierPath.ElementType.
Discussion
If you specify a value for the points parameter, your array must be large enough to hold the number of points for the given path element. Move, close path, and line segment commands return one point. Curve operations return three points.
For curve operations, the order of the points is controlPoint1 (points[0]), controlPoint2 (points[1]), endPoint (points[2]).
