# CGLineJoin

Junction types for stroked lines.

```
enum CGLineJoin
```

## Overview

A line join specifies how [`strokePath()`](/documentation/CoreGraphics/CGContext/strokePath()) draws the junction between connected line segments. To set the line join style in a graphics context, you use the function [`setLineJoin(_:)`](/documentation/CoreGraphics/CGContext/setLineJoin(_:)).

## Topics

### Constants

[`CGLineJoin.miter`](/documentation/CoreGraphics/CGLineJoin/miter)

[`CGLineJoin.round`](/documentation/CoreGraphics/CGLineJoin/round)

A join with a rounded end. Core Graphics draws the line to extend beyond the endpoint of the path. The line ends with a semicircular arc with a radius of 1/2 the line’s width, centered on the endpoint.

[`CGLineJoin.bevel`](/documentation/CoreGraphics/CGLineJoin/bevel)

A join with a squared-off end. Core Graphics draws the line to extend beyond the endpoint of the path, for a distance of 1/2 the line’s width.
