Class RotateFilter

java.lang.Object
  net.sf.jaer.eventprocessing.EventFilter
      net.sf.jaer.eventprocessing.EventFilter2D
          net.sf.jaer.eventprocessing.filter.RotateFilter

All Implemented Interfaces:

java.util.Observer

public class RotateFilter
extends EventFilter2D
implements java.util.Observer

Transforms the events in various ways, e.g. rotates the events so that x becomes y and y becomes x. This filter acts on events in-place in the packet so it should be rather fast because it doesn't need to copy events, only modify them.
