Class GLTextureLoader

java.lang.Object

maspack.render.GL.GLTextureLoader

All Implemented Interfaces:

GLGarbageSource

public class GLTextureLoader
extends java.lang.Object
implements GLGarbageSource

A utility class to load textures for JOGL. This source is based on a texture that can be found in the Java Gaming (www.javagaming.org) Wiki. It has been simplified slightly for explicit 2D graphics use. OpenGL uses a particular image format. Since the images that are loaded from disk may not match this format this loader introduces a intermediate image which the source image is copied into. In turn, this image is used as source for the OpenGL texture.
