Instance Method

Adds a sequence of connected straight-line segments to the path.

## Parameters

`points`

An array of values that specify the start and end points of the line segments to draw. Each point in the array specifies a position in user space. The first point in the array specifies the initial starting point.

`transform`

An affine transform to apply to the points before adding to the path. Defaults to the identity transform if not specified.

## Discussion

Calling this convenience method is equivalent to calling the `move(to:transform:)` method with the first value in the `points` array, then calling the `addLine(to:transform:)` method for each subsequent point until the array is exhausted. After calling this method, the path’s current point is the last point in the array.

### Constructing a Graphics Path

`func move(to: CGPoint, transform: CGAffineTransform)`

Begins a new subpath at the specified point.

`func addLine(to: CGPoint, transform: CGAffineTransform)`

Appends a straight line segment from the current point to the specified point.

`func addRects([CGRect], transform: CGAffineTransform)`

Adds a set of rectangular subpaths to the path.

`func addEllipse(in: CGRect, transform: CGAffineTransform)`

Adds an ellipse that fits inside the specified rectangle.

`func addArc(tangent1End: CGPoint, tangent2End: CGPoint, radius: CGFloat, transform: CGAffineTransform)`

Adds an arc of a circle to the path, specified with a radius and two tangent lines.

`func addCurve(to: CGPoint, control1: CGPoint, control2: CGPoint, transform: CGAffineTransform)`

Adds a cubic Bézier curve to the path, with the specified end point and control points.

`func addQuadCurve(to: CGPoint, control: CGPoint, transform: CGAffineTransform)`

Adds a quadratic Bézier curve to the path, with the specified end point and control point.

`func closeSubpath()`

Closes and completes a subpath in a mutable graphics path.
