Interface RasterLayerService

All Superinterfaces:

LayerService

@Api(allMethods=true)
public interface RasterLayerService
extends LayerService

Service which allows accessing data from a raster layer.

All access to raster layers should be done through this service, not by accessing the layer directly as this adds possible modifications in the data. These services are implemented using pipelines (see PipelineService) to make them configurable.

Since:

1.6.0

Method Detail

getTiles

List<RasterTile> getTiles(String layerId,
                        CoordinateReferenceSystem crs,
                        com.vividsolutions.jts.geom.Envelope bounds,
                        double scale)
                          throws GeomajasException

Get the raster tiles for the specified bounds, optimized for the scale in pixels/unit.

Parameters:

layerId - layer id

crs - Coordinate reference system used for bounds

bounds - bounds to request images for

scale - scale or zoom level (unit?)

Returns:

a list of raster images that covers the bounds

Throws:

GeomajasException - oops
