# GraphicsContext.BlendMode

The ways that a graphics context combines new content with background content.

## Declaration

```swift
@frozen struct BlendMode
```

## Overview

Overview Use one of these values to set the blendMode property of a GraphicsContext. The value that you set affects how content that you draw replaces or combines with content that you previously drew into the context.
