Class ImageBuffer

java.lang.Object
  org.newdawn.slick.ImageBuffer

All Implemented Interfaces:

ImageData

public class ImageBuffer
extends java.lang.Object
implements ImageData

A utility for creating images from pixel operations Expected usage is: ImageBuffer buffer = new ImageBuffer(320,200); buffer.setRGBA(100,100,50,50,20,255); .. Image image = buffer.getImage();
