# UIGraphicsImageRendererFormat

A set of drawing attributes that represents the configuration of an image renderer context.

```
class UIGraphicsImageRendererFormat
```

## Overview

Use an instance of [`UIGraphicsImageRendererFormat`](/documentation/UIKit/UIGraphicsImageRendererFormat) to initialize a [`UIGraphicsImageRenderer`](/documentation/UIKit/UIGraphicsImageRenderer) object with nondefault attributes.

The image renderer format object contains properties that determine the attributes of the underlying Core Graphics contexts that the image renderer creates. Use the [`default()`](/documentation/UIKit/UIGraphicsRendererFormat/default()) class method to create an image renderer format instance optimized for the current device.

## Topics

### Creating the renderer

[`init(for:)`](/documentation/UIKit/UIGraphicsImageRendererFormat/init(for:))

Creates the most suitable format for rendering on a device with the specified traits.

### Configuring the renderer attributes

[`opaque`](/documentation/UIKit/UIGraphicsImageRendererFormat/opaque)

A Boolean value that indicates whether the underlying Core Graphics context has an alpha channel.

[`scale`](/documentation/UIKit/UIGraphicsImageRendererFormat/scale)

The display scale of the image renderer context.

[`preferredRange`](/documentation/UIKit/UIGraphicsImageRendererFormat/preferredRange)

The preferred color range of the image renderer context.

[`UIGraphicsImageRendererFormat.Range`](/documentation/UIKit/UIGraphicsImageRendererFormat/Range)

Constants that specify the color range of the image renderer context.

[`prefersExtendedRange`](/documentation/UIKit/UIGraphicsImageRendererFormat/prefersExtendedRange)

A Boolean value that specifies whether the bitmap context uses extended color.
