Constructor Detail

OWSRasterLayer

public OWSRasterLayer(String name,
                      URL baseURL)
               throws Exception

Parameters:

name -

baseURL -

Throws:

Exception

Method Detail

setCoordinatesSystem

public void setCoordinatesSystem(CoordinateSystem crs)
                          throws Exception

Description copied from interface: Layer

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 -

Throws:

Exception

getBoundingBox

public Envelope getBoundingBox()

Description copied from class: AbstractLayer

returns the BoundingBox (Envelope) of Layer. This is the BoundingBox of the layers data. The BoundingBox of the View maybe larger or smaller

Specified by:

getBoundingBox in interface Layer

Overrides:

getBoundingBox in class AbstractLayer

Returns:

the BoundingBox (Envelope) of Layer

getRaster

public GridCoverage getRaster(Envelope envelope,
                              double w,
                              double h)
                       throws IOException

Parameters:

envelope -

w - width of image

h - height of image

Returns:

grid coverage for envelope and size

Throws:

IOException
