java.lang.Object

org.gvsig.raster.impl.store.FramedBufferResampling

public class FramedBufferResampling
extends Object

The requests to a RasterDataStore adjust the bounding box and the size in pixels to the source limits. The user can need a buffer that exceeds the raster dimension. In this case, the area that is out of the raster limits should be set to nodata values or transparent in RGB cases.
