Class IlvMapScaleLimiter

java.lang.Object

ilog.views.maps.IlvMapScaleLimiter

All Implemented Interfaces:

TransformerListener, EventListener

public class IlvMapScaleLimiter
extends Object
implements TransformerListener

Class that limits the scale range of a IlvManagerView. You can constraint the scale of a map by calling :

  IlvMapScaleLimiter limiter = new IlvMapScaleLimiter(1,1/1E9);
  limiter.setView(view);
  

Since:

JViews 7.5
