org.geomajas.layer.wms.WmsLayer

Layer model for accessing raster data from WMS servers. It has support for most WMS versions: up to 1.3.0. When using this layer, note that the following fields are required:

baseWmsUrl: The base URL to the WMS server.
format: The format for the returned images.
version: The version of WMS to use.
styles: The styles to use when rendering the WMS images.
useProxy: Set to true to use a proxy for rendering the WMS, hiding the URL from the client. This automatically happens when setting the authentication object.

There always is the option of adding additional parameters to the WMS GetMap requests, by filling the parameters list. Such parameters could include optional WMS GetMap parameters, such as "transparency", but also "user" and "password".

This layer also supports BASIC and DIGEST authentication. To use this functionality, set the authentication field.
