LowerThreshold¶
Summary
This property gets and sets the lower threshold in the scale at which to display the image.
Remarks
Below the lower threshold in scale, the image will not be displayed. This, in conjunction with the UpperThreshold property, allows you to create a band in which it is suitable to display the image source. By default, the upper threshold is double.max and lower threshold is double.min. This means the image should always display.

IsOpenCore¶
Summary
This property returns true if the RasterLayer is open and false if it is not.
Remarks
Various methods on the RasterLayer require that it be in an open state. If one of those methods is called when the state is not open, then the method will throw an exception. To enter the open state, you must call the RasterLayer's Open method. The method will raise an exception if the current RasterLayer is already open.

CloseCore()¶
Summary
This method opens the RasterLayer so that it is initialized and ready to use.
Remarks
The close method plays an important role in the life cycle of the RasterLayer. 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 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.

DrawCore(GeoCanvas,Collection<SimpleCandidate>)¶
Summary
This method will draw the image from the NativeImage source based on the parameters provided.
Remarks
The DrawCore method will be called when the layer is being drawn. It will determine if the image is within the extent and the threshold defined. If these parameters are met, it will query the RasterSource for an image and then apply the other various properties (such as transparency, etc.) on the image. Lastly, it will draw the image on the NativeImage or native image passed into the method.

OpenCore()¶
Summary
This method opens the RasterLayer so that it is initialized and ready to use.
Remarks
The open method plays an important rol,e as it is responsible for initializing the RasterLayer. Most methods on the RasterLayer will throw an exception if the state of the RasterLayer is not opened. When the map draws each layer, it will open the RasterLayer 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 RasterLayer.
