Class ExtendViewport

java.lang.Object

com.badlogic.gdx.utils.viewport.Viewport

com.badlogic.gdx.utils.viewport.ExtendViewport

public class ExtendViewport
extends Viewport

A viewport that keeps the world aspect ratio by extending the world in one direction. The world is first scaled to fit within the viewport, then the shorter dimension is lengthened to fill the viewport. A maximum size can be specified to limit how much the world is extended and black bars (letterboxing) are used for any remaining space.
