Hi Subha, I think for the "mode=legend" to work, you need to change the LAYER status to DEFAULT. However, you can test the legend function via WMS request without changing the status by using a request similar to this: (linebreaks added for clarity)
http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/states/states.map &service=wms &version=%221.1.1%22 &request=GetLegendGraphic &layer=countries &styles= &width=60 &height=40 &format=png Roger -- On Tue, Oct 7, 2008 at 11:38 PM, Subha Ramakrishnan <[EMAIL PROTECTED]> wrote: > Fawcett, David wrote: > >> Or, just a straight mode=legend request to the CGI if you are using >> MapServer.
