# addLine(to:transform:)

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

## Declaration

```swift
func addLine(to point: CGPoint, transform: CGAffineTransform = .identity)
```

## Parameters

- `point`: The location, in user space coordinates, for the end of the new line segment.
- `transform`: An affine transform to apply to the point before adding to the path. Defaults to the identity transform if not specified.

## Discussion

Discussion After adding the line segment, the current point is set to the endpoint of the line segment.
