Class RasterizeFLayers

java.lang.Object

org.gvsig.raster.tools.algorithm.saveraster.RasterizeFLayers

All Implemented Interfaces:

BaseIncrementableTask, DataServerWriter, IIncrementable, Disposable

public class RasterizeFLayers
extends Object
implements DataServerWriter, IIncrementable

Sirve datos solicitados por los drivers que salvan a raster. Hereda de Rasterizer y reescribe el método readData que es el que será llamado desde el driver cada vez que vacie el buffer y necesite más datos.
