# setContentsRectNeedsUpdate()

Informs the view that contains the image when the layout changes and the view needs to reload its content.

## Declaration

```swift
@MainActor final func setContentsRectNeedsUpdate()
```

## Mentioned in

Enabling Live Text interactions with images

## Discussion

Discussion The framework ignores calls to this method when the superview is of type NSImageView. If the superview is a class other than NSImageView, call this method when the layout changes. The overlay view then invokes the delegate’s contentsRect(for:) method to request the new content area.
