# lighten

A mode that creates composite image samples by choosing the lighter samples from either the source image or the background.

## Declaration

```swift
static var lighten: GraphicsContext.BlendMode { get }
```

## Discussion

Discussion When you draw in this mode, source image samples that are lighter than the background replace the background. Otherwise, the background image samples remain unchanged.
