Class Zoomer

  • All Implemented Interfaces:
    com.badlogic.gdx.utils.Disposable
    public final class Zoomer
extends PostProcessorEffect
    Implements a zooming effect: either a radial blur filter or a zoom filter is used.

    • Constructor Summary

      Constructors 
      Constructor Description
      Zoomer​(int viewportWidth, int viewportHeight)
      Creating a Zoomer without any parameter will use plain simple zooming
      Zoomer​(int viewportWidth, int viewportHeight, RadialBlur.Quality quality)
      Creating a Zoomer specifying the radial blur quality will enable radial blur
