# init(cgImage:size:)

Creates a new image using the contents of the provided image.

## Declaration

```swift
convenience init(cgImage: CGImage, size: NSSize)
```

## Parameters

- `cgImage`: The source image.
- `size`: The size of the new image. Use doc://com.apple.documentation/documentation/CoreFoundation/CGSize/zero, or doc://com.apple.documentation/documentation/Foundation/NSZeroSize in Objective-C, to have the new image adopt the pixel dimensions of the source image.

## Discussion

Discussion Don’t assume anything about the image, other than drawing it is equivalent to drawing the source image. This is not a designated initializer.
