Implemented Interfaces:
ByteChannelImage, Gray8Image, GrayImage, GrayIntegerImage, IntegerImage, PixelImage

public class MemoryGray8Image
extends MemoryByteChannelImage
implements Gray8Image

An implementation of Gray8Image that keeps the complete image in memory. This class inherits most of its functionality from its parent class MemoryByteChannelImage, using one byte channel.
