# plusLighter

A mode that adds the components of the source and background images,
resulting in a lightened composite.

```
static var plusLighter: GraphicsContext.BlendMode { get }
```

## Discussion

This mode implements the equation `R = MIN(1, S + D)` where

- `R` is the composite image.
- `S` is the source image.
- `D` is the background.
