Hi all,

I got a question about GetLegendGraphic request in Mapserver.  I can
sucessfully use GetLegendGraphic to get any legend icons without any
problem when a layer with one class object and one symbol sign.  But
when a layer contains more than one class objects and symbols in it then
I have a question about it :)  I can get all the symbols that I specific
in a layer but the problem I have right now is those symbols are
overlapped with each other when I make a GetLegendGraphic request.  I
use the GetLegendRequest as followed:
http://localhost/cgi-bin/wms?version=3D1.1.1&Layer=3Dtest&request=3DGetLe=
gendG
raphic&format=3Dimage/png

I just wonder if there is a way to get legend icon with each symbol I
specified in this layer.  Could anyone give me a hint ?

Any help would be greatly appreciated.

Thanks in advance,

Stephanie  =20
