```
public class CanvasPixelArray
extends JavaScriptObject
```
Array-like object holding the actual image data for an ImageData object. For each pixel, this object contains a red, green, blue and alpha value between 0 and 255 (in this order). Note that we use ints here to represent the data to avoid complexities stemming from bytes being signed in Java.
