<!– Class –> Represents an object that encapsulates a Web Map Service (WMS) layer.

A Web Map Service (WMS) produces maps of spatially referenced data dynamically from geographic information. This International Standard defines a “map” to be a portrayal of geographic information as a digital image file suitable for display on a computer screen. A map is not the data itself. WMS-produced maps are generally rendered in a pictorial format such as PNG, GIF or JPEG, or occasionally as vector-based graphical elements in Scalable Vector NativeGraphics (SVG) or Web Computer NativeGraphics Metafile (WebCGM) formats.

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.

This property indicates the format in which the client wishes to be notified of service exceptions.

Upon receiving a request that is invalid according to the OGC standard, the server shall issue a service exception report. The service report is meant to describe to the client application or its human user the reason(s) that the request is invalid.

This property gets and sets the ImageSource used by the RasterLayer.

The set for this property is protected and only intended to be used by developers who are creating their own ImageSources. This is the main property to set for developers who are creating their own RasterLayer derivatives.

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.

<!– ThinkGeo.MapSuite.PortableCore.WmsRasterLayer –> Go Back

This property gets and set the visible state of the layer.

If this property is set to false, the layer will not draw. We ensure this in the Draw method. This is useful for legends and other controls that control the visibility of layers.

<!– ThinkGeo.MapSuite.PortableCore.Layer –> Go Back

Gets a value represents a collection of key colors. If HasKeyColor property is false, it will throw exception when you use KeyColors.

It will make these colors transparent when draw image.

This property gets and sets the lower threshold in the scale at which to display the image.

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.

<!– ThinkGeo.MapSuite.PortableCore.RasterLayer –> Go Back

This property gets and sets the name for the layer.

The name is user defined. It is useful to set, as it may be used for higher level components such as legends, etc.
