# CGColorConversionInfo

An object that describes how to convert between color spaces for use by other system services.

```
class CGColorConversionInfo
```

## Overview

A [`CGColorConversionInfo`](/documentation/CoreGraphics/CGColorConversionInfo) object specifies a conversion between two or more color spaces, including information about the intent of the conversion. You use color conversion objects to specify the work to be done by an <doc://com.apple.documentation/documentation/MetalPerformanceShaders/MPSImageConversion> filter, which can then perform GPU-accelerated image conversion.

## Topics

### Creating a Color Conversion

[`init(src:dst:)`](/documentation/CoreGraphics/CGColorConversionInfo/init(src:dst:))

Creates a conversion between two specified color spaces.

[`init(optionsSrc:dst:options:)`](/documentation/CoreGraphics/CGColorConversionInfo/init(optionsSrc:dst:options:))

[`CGColorConversionInfoCreateFromList`](/documentation/CoreGraphics/CGColorConversionInfoCreateFromList)

Creates a conversion between an arbitrary number of specified color spaces.

[`CGColorConversionInfoTransformType`](/documentation/CoreGraphics/CGColorConversionInfoTransformType)

Constants describing how a color conversion uses color spaces.

### Color Conversion Options

Use these keys in the options dictionary when calling `CGColorConversionInfoCreateFromList`.

[`conversionBlackPointCompensation`](/documentation/CoreGraphics/CGColor/conversionBlackPointCompensation)

An option for whether to apply black point compensation when converting between color profiles.

### Working with Core Foundation Types

[`typeID`](/documentation/CoreGraphics/CGColorConversionInfo/typeID)

Returns the Core Foundation type identifier for a color conversion info data type.

### Instance Methods

[`convert(width:height:to:format:from:format:options:)`](/documentation/CoreGraphics/CGColorConversionInfo/convert(width:height:to:format:from:format:options:))
