Environment2D

Class Viewport2D

java.lang.Object

java.awt.Graphics

Environment2D.Viewport2D

public class Viewport2D
extends java.awt.Graphics

Represents a 'camera' - a visible section of an Environment2D plane which is passed to the rendering routines in order to produce output. This allows the output to be adjusted to accurately represent the plane no matter what size the output is.
