All Implemented Interfaces:

public class IntegerRaster
extends MeasuredImage
implements Dimensioned

A IntegerRaster contains an array of integers where each integer represents an image pixel. Because the image created by a IntegerRaster cannot be resized, the image dimensions are the same as the dimensions of the integer array.
