# clear(_:)

Paints a transparent rectangle.

## Declaration

```swift
func clear(_ rect: CGRect)
```

## Parameters

- `rect`: The rectangle, in user space coordinates.

## Discussion

Discussion If the provided context is a window or bitmap context, Core Graphics clears the rectangle. For other context types, Core Graphics fills the rectangle in a device-dependent manner. However, you should not use this function in contexts other than window or bitmap contexts.
