[mapserver-users] Mapserver as WMS client, legend pass-through . . .

Tue Jun 12 10:53:47 PDT 2012

Barend,

I'm using GeoMoose, it has a separete menu for displaying the Legend chips integrated into it.

I'm still pondering some ideas . . .

Hmm, I clearly didn't read your original post well enough, sorry... The
easy solution would be to have the legend embedded in the WMS image (use
STATUS EMBED in the LEGEND object). Won't be useful if you want the WMS in
a tiled fashion, though...
