Package icyllis.arc3d.sketch.j2d

Class Raster

java.lang.Object

icyllis.arc3d.sketch.j2d.Raster

All Implemented Interfaces:

AutoCloseable

public class Raster
extends Object
implements AutoCloseable

Raster is similar to Bitmap, they are all "raster" (pixel map), but this class wraps Java2D's Raster. Pixels are allocated on the Java heap, and can be used with Java2D's software renderer.
