[mapserver-users] How to Create Legend for Single Layer

[Venkat Rao Tammineni]

Hi,

 Thanks  for your great response.I  am not using CGI.I am using  asp
C#.net.I have created a method which generates legend.But it is doing for
all the layers.And my layer does  the expression property.based on the
expression I m displaying polygon.

   Below code is for trying to get legend for single layer.But it is not
working.

            layer = MapFunction.Map.getLayerByName("TestLayer");
            classObj classLegend = new classObj(layer);
            imageObj imagelegend = MapFunction.Map.drawLegend();
            string strFile ="C:\\temp\\test.png";
            imagelegend.save(strFile,MapFunction.Map);


Thanks
Venkat.

Hi,

You can do so using mode=legend request. Eg: 
"http://localhost/cgi-bin/mapserv?mode=legend&map=mapfile&layer=layer_name"
This will give the legend only for the layer that you pass in the url.

In addition to this, is there a facility to generate legend for a layer 
with a filter, where the filter takes in parameters passed from URL to 
generate polygons??

Thanks & regards,
Subha
