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.Constructor and Description |
