Class ViewPortData

java.lang.Object
  org.cresques.geo.ViewPortData

All Implemented Interfaces:

Projected

public class ViewPortData
extends Object
implements Projected

Datos de vista sobre las capas. Mantiene un conjunto de datos necesarios, que describen el modo de ver las capas actual. cmartinez: Esta clase no debería formar parte de una API, pero se deja hasta que se aborde el refactoring de libProjection.
