[Mapserver-DE] Re: [Mapserver-users] SLd GetMap & GetLegendGraphic

[bartvde@xs4all.nl]

Hi Till,

Yes GetLegendGraphic can only be used on one layer (this is by spec and
not specific for Mapserver).

We will be doing some enhancements to the GetLegendGraphic operation in
the near future, see the following bug for a discussion of this:

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=653

Best regards,
Bart
