Change the style of a Web Map Service (WMS) layer.

Image of style WMS layers

Use case

Layers hosted on WMS may have different pre-set styles available to apply to them. Swapping between these styles can help during visual examination of the data. For example, increasing the contrast of satellite images can help in identifying urban and agricultural areas within forested areas.

How to use the sample

Once the layer loads, the toggle button will be enabled. Click it to toggle between the first and second styles of the WMS layer.

How it works

Create a WmsLayer specifying the URL of the service and the layer names you want new WmsLayer(url, names).
When the layer is done loading, get it's list of style strings using wmsLayer.Sublayers[0].SublayerInfo.Styles.
Set one of the styles using the wmsLayer.Sublayers[0].CurrentStyle property.
