<!– Class –> The ScaleBarAdornmentLayer class allows you show a bar graphic on the map that displays the distance scale for the current map extent.
Use the <strong>ScaleBarAdornmentLayer</strong> class as a quick way to implement a <strong>ScaleBar</strong>. When using the <strong>ScaleBarAdornmentLayer</strong>, you also need to add a ScaleLineAdornmentLayer to the map control. One thing we should pay attention to is that the ScaleBar will not be drawn when the CurrentExtent is outside of Range(-90,180,90,-180).

Creates a new instance of the ScaleBarAdornmentLayer class.
When displaying a <strong>ScaleBarAdornmentLayer</strong>, we need to instance a ScaleLineAdornmentLayer and add it to MapEngine. The ScaleBar will not be drawn when the <strong>CurrentExtent</strong> is outside of the world Extent(-90,180-,90,-180).

Create a copy of Layer using the deep clone process.
The difference between deep clone and shallow clone is as follows: In shallow cloning, only the object is copied; the objects within it are not. By contrast, deep cloning copies the cloned object as well as all the objects within.

This method closes the Layer and releases any resources it was using.
This method is the concrete wrapper for the abstract method CloseCore. The close method plays an important role in the life cycle of the Layer. 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 Layer 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.
As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

This method opens the Layer so that it is initialized and ready to use.
This method is the concrete wrapper for the abstract method OpenCore. The open method plays an important role, as it is responsible for initializing the Layer. Most methods on the Layer will throw an exception if the state of the Layer is not opened. When the map draws each layer, the layer will be opened 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 Layer.
When implementing the abstract method, consider opening the FeatureSource or RasterSource. You will get a chance to close these in the Close method of the Layer.
As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs.

This method draws the Layer.
This abstract method is called from the concrete public method Draw. This method draws the representation of the layer based on the extent you provided.
When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.

This property returns true if the Layer is open and false if it is not.
This method is the concrete wrapper for the abstract method IsOpenCore. Various methods on the Layer 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 Layer Open method. The method will raise an exception if the current Layer is already open.

This property returns true if the Layer is open and false if it is not.
Various methods on the Layer 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 Layer Open method. The method will raise an exception if the current Layer is already open.
