[mapserver-users] Exclude one layer's class from GetLegendGraphics

[Steve.Toutant at inspq.qc.ca]

Perhaps you could use 
RULE - (Optional) Specify the name of the CLASS to generate the legend 
image for (as opposed to generating an icon and label for ALL classes for 
the layer).
http://mapserver.org/ogc/wms_server.html

Perhaps you can put several rule in the WMS call

I just realize that RULE is not included in the Mapserver CLASS doc

For your second question, encoding is still a mystery I'm trying to 
understand....

Re: [mapserver-users] Exclude one layer's class from GetLegendGraphics








Hi,

For the first question I am remembering that only classes with NAME go to 
the legend. I may be wrong but you can try it easily.
