Class IlvRasterSplitter

java.lang.Object

ilog.views.maps.raster.IlvRasterSplitter

public class IlvRasterSplitter
extends Object

IlvRasterSplitter creates layers from IlvTiledLayer objects and adds the appropriate IlvFreeTile instances for a specified IlvRasterAbstractReader. This is useful for displaying huge images, even if they need to be projected using an IlvProjection. Once returned by one of the createTiledLayers methods, tiled layers can be added to an IlvManager instance and be displayed in an IlvManagerView object.

IlvRasterSplitter

public IlvRasterSplitter(IlvTileCache cache)

Constructs an IlvRasterSplitter instance using the specified IlvTileCache.

Parameters:

cache - The IlvTileCache instance to be used by the IlvTiledLayer objects created by this class.

Method Detail

createTiledLayers

public Collection<IlvTiledLayer> createTiledLayers(IlvRasterAbstractReader reader,
                                                   int maxSamplingLevels,
                                                   int samplingLevelRatio,
                                                   IlvTiledLayer[] tiledLayers,
                                                   boolean allowSubsampling)

Creates and sets up the list of IlvTiledLayer objects used to contain and draw the raster data produced by an IlvRasterAbstractReader instance.

Parameters:

reader - The IlvRasterAbstractReader instance that produces raster data.

maxSamplingLevels - The maximum number of tiled layers to create. One layer per subsampling resolution.

samplingLevelRatio - The ratio between two consecutive subsampling levels.

tiledLayers - An array of IlvTiledLayer objects used to store the tiled layers created.

allowSubsampling - Set to true to allow tiles to create IlvRasterIcon components that manage their own subsampling level. See IlvRasterIcon.

Returns:

A collection of IlvTiledLayer instances.

createTiledLayers

public Collection<IlvTiledLayer> createTiledLayers(IlvRasterAbstractReader reader,
                                                   int maxSamplingLevels,
                                                   int samplingLevelRatio,

                                                   boolean allowSubsampling,
                                                   boolean threaded)

Creates and sets up the list of IlvTiledLayer objects used to contain and draw raster data produced by an IlvRasterAbstractReader instance.

Parameters:

reader - The IlvRasterAbstractReader that produces raster data.

maxSamplingLevels - The maximum number of tiled layers to create. One layer per subsampling resolution.

samplingLevelRatio - The ratio between to consecutive subsampling levels.

tiledLayers - An array of IlvTiledLayer objects used to store the tiled layers created.

allowSubsampling - Set to true to allow tiles to create IlvRasterIcon components that manage their own subsampling level. See IlvRasterIcon for more information.

threaded - Set to true to allow multithreading for tile loading.

Returns:

A collection of IlvTiledLayer instances.
