Class RasterLayer

java.lang.Object
  org.deegree.graphics.AbstractLayer
      org.deegree.graphics.RasterLayer

All Implemented Interfaces:

Layer

 class RasterLayer
extends AbstractLayer

A RasterLayer represent a layer which data are contained within one single Image. The image/raster is geo-referenced by a Envelope that is linked to it.

RasterLayer

RasterLayer(String name,
            GridCoverage raster)
      throws Exception

Creates a new AbstractLayer object.

Parameters:

name -

raster -

Throws:

Exception

RasterLayer

RasterLayer(String name,
            GridCoverage raster,
            GetMap request)
      throws Exception

Throws:

Exception

Method Detail

setCoordinatesSystem

public void setCoordinatesSystem(CoordinateSystem crs)
                          throws Exception

sets the coordinate reference system of the MapView. If a new crs is set all geometries of GeometryFeatures will be transformed to the new coordinate reference system.

Parameters:

crs - to set

Throws:

Exception - if something went wrong

getRaster

public GridCoverage getRaster()

returns the image/raster that represents the layers data

Returns:

the image/raster that represents the layers data

getRequest

GetMap getRequest()

setRaster

public void setRaster(GridCoverage raster)
               throws Exception

sets the image/raster that represents the layers data

Parameters:

raster - the image/raster that represents the layers data

Throws:

Exception - if the bbox of the layer could not be calculated
