All Implemented Interfaces:

PixelCoordinateOverlay
```
public class RemoveTransparentShuffleOverlay
extends ShuffleOverlay
```
This class returns Pixels of the underlying Bitmap in a random order determined by the seed that is given to its constructor.

It will only return Pixels with an alpha value greater than 0.
