Parameters
OpenCore()
This protected virtual method is called from the concrete public method Open. The Open method plays an important role, as it is responsible for initializing the ImageSource. Most methods on the ImageSource will throw an exception if the state of the ImageSource is not opened. When the map draws each layer, it will open the ImageSource as one of its first steps; then, after it is finished drawing with that layer, it will close it. In this way, we are sure to release all resources used by the ImageSource. When implementing this abstract method, consider opening files for file-based sources, connecting to databases in the database-based sources and so on. You will get a chance to close these in the Close method of the ImageSource.
Return Value
Type:Void
Description:None
Parameters
CloseCore()
This protected virtual method is called from the concrete public method Close. The Close method plays an important role in the life cycle of the ImageSource. It may be called after drawing to release any memory and other resources that were allocated since the Open method was called. If you override this method, it is recommended that 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 FeatureSource 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.

Public Events
StreamLoading
If you wish, you can pass in your own stream to represent the image. The stream can come from a variety of places, including isolated storage, a compressed file, or an encrypted stream. When the image is finished with the stream it will dispose of it, so be sure to keep this in mind when passing the stream in. If you do not pass in an alternate stream, the class will attempt to load the file from the file system using the PathFileName property.
