# rotate(by:)

Rotates subsequent drawing operations by an angle.

## Declaration

```swift
mutating func rotate(by angle: Angle)
```

## Parameters

- `angle`: The amount to rotate.

## Discussion

Discussion Calling this method is equivalent to updating the context’s transform directly using the angle parameter: transform = transform.rotated(by: angle.radians)
