-The close method plays an important role in the life cycle of the RasterLayer.

If you override this method, it is recommended that you take the following things into account: This method may be called multiple times, so we suggest you write the method so that that a call to a closed RasterLayer is ignored and does not generate an error. We also suggest that in the Close you free all resources that have been opened. Remember that the object will not be destroyed, but will be re-opened possibly in the near future.+  * //The close method plays an important role in the life cycle of the RasterLayer.
