# init(src:dst:)

Creates a conversion between two specified color spaces.

## Declaration

```swift
init?(src: CGColorSpace, dst: CGColorSpace)
```

## Parameters

- `src`: The source color space from which color values are to be converted.
- `dst`: The destination color space to which colors are to be converted.

## Return Value

Return Value A color conversion object, or nil if no conversion between the specified color spaces is allowed.

## Discussion

Discussion The source and destination color spaces must be calibrated color spaces (that is, not device-specific or indexed color spaces). You can use a color conversion object to create MPSImageConversion filters that perform GPU-accelerated color space conversion.
