# SKCropNode

A node that masks pixels drawn by its children so that only some pixels are seen.

## Declaration

```swift
class SKCropNode
```

## Mentioned in

About Node Drawing Order

## Overview

Overview SKCropNode is a container node that you use to crop other nodes in the scene. You add other nodes to a crop node and set the crop node’s maskNode property. For example, here are some ways you might specify a mask: An untextured sprite that limits content to a rectangular portion of the scene. A textured sprite that works as a precise per-pixel mask. A collection of child nodes that form a unique shape. You can animate the shape or contents of the mask to implement interesting effects such as hiding or revealing. tip: Use crop nodes sparingly. Because they require an additional offscreen memory buffer to perform the crop and add a rendering operation into the offscreen buffer, they add notably more overhead to the app.
