org.gvsig.fmap.mapcontext.layers.Tiling

public class Tiling
extends java.lang.Object

Cálculo de Partes (Tiles) en las que se divide un raster grande. Se usa para imprimir rasters y capas raste remotas (WMS). Para no pedir imagenes demasiado grandes, vamos a hacer lo mismo que hace EcwFile: chunkear. Llamamos a drawView con cuadraditos más pequeños del BufferedImage ni caso, cuando se imprime viene con null código original de Fran Peñarrubia
