                  int bandNr,
                  boolean malloc)

Description copied from interface: RasterManager

Genera instancias del buffer de datos adecuado al tamaño del raster. Si no hay muchos datos (menos de cacheMemorySize) creará un buffer en memoria. Si hay más de esta cantidad entonces crearemos un buffer cacheado (RasterCache). A partir de la cantidad señalada por multicacheMemorySize haremos un buffer cacheado donde cada página no ocupa todo el ancho del raster ya que este será muy grande. La gestión de una cache donde cada pagina ha de partir una línea lleva una complejidad añadida.
