This is a simple plugin for leaflet that will display a WMS GetLegendGraphic request result in a legend. At the moment the plugin is really, really simple in that is actually will display any image URI you pass it on initialisation. However that is enough to create a nice looking legend on your map like this:
To use it simply include the supplied javascript and css files (make sure the js file comes after the main leaflet js file):
<link rel="stylesheet" href="../css/leaflet.wmslegend.css"/>
<script src="../js/leaflet.wmslegend.js"></script>
Then add a call to the legend control as per this example:
uri = "http://maps.kartoza.com/cgi-bin/qgis_mapserv.fcgi?";
uri += "map=/web/Boosmansbos/Boosmansbos.qgs&";
uri += "&SERVICE=WMS&VERSION=1.3.0&SLD_VERSION=1.1.0&";
uri += "REQUEST=GetLegendGraphic&FORMAT=image/jpeg&LAYER=Boosmansbos&STYLE=";
L.wmsLegend(uri);
For a complete example, please see example.html in the source tree. You can also visit http://maps.kartoza.com as various of our demos there use the legend control provided here.
