# init(ioSurface:)

Initializes an image with the contents of an IOSurface.

## Declaration

```swift
init(ioSurface surface: IOSurfaceRef)
```

## Parameters

- `surface`: An IOSurface object.

## Return Value

Return Value An image object initialized with the data from the IOSurface object.

## Discussion

Discussion An IOSurface object is a framebuffer object that is suitable for sharing across process boundaries. You can use it to allow your app to move complex image decompression and drawing logic into a separate process for the purpose of increasing security.
