# cropRect

Indicates the bounding rectangle of the screen area to be captured, in pixels.

## Declaration

```swift
var cropRect: CGRect { get set }
```

## Discussion

Discussion By default, AVCaptureScreenInput captures the entire area of the displayID with which it is associated. Set the value of this property to limit the capture rectangle to a subsection of the screen. The rectangle should define a smaller section of the screen in the screen’s coordinate system. The origin (0,0) is the bottom-left corner of the screen.
