com.vividsolutions.jump.workbench.imagery.ecw.JNCSRendererProxy

public class JNCSRendererProxy
extends Object

The purpose of this proxy class is to defer linking to the proprietary ECW ER Mapper library till runtime. So it's not necessary to ship the library and/or its Java wrapper in binary distributions of OpenJUMP.
