[mapserver-users] html legend not working

[Rahkonen Jukka (MML)]

Hi,

By a quick look at http://mapserver.org/ogc/wms_server.html you should probably add text/html as a GetLegendGraphic format:
wms_getlegendgraphic_formatlist

    Description: (Optional) A comma-separated list of valid formats for a WMS GetLegendGraphic request.

and then use &format=text/html in your request. However, I have not tried that myself but this is just my best guess.

http://localhost/cgi-bin/mapserv?MAP=/home/www/geomoose-2.8.0/maps/cen_default//cen_default.map&FORMAT=image/png&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&_OLSALT=0.9622128666378558&SRS=EPSG:3857&SCALE=6933486.650500195&WIDTH=250&STYLE=&LAYER=sostegni

The legend is returned a png file, just like TEMPLATE statement wasn't taken into account.


Any hint?
