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

[Basques, Bob (CI-StPaul)]

Daniel,

So, I have this (direct) URL for a legend graphic from the upstream WMS server:

http://wsgisserver.water.stpaul.city/ArcGIS/services/AUTOCAD/MapServer/WMSServer?request=GetLegendGraphic&version=1.3.0&format=image/png&layer=2&width=200

Any ideas on how to use this direct link to add a legend to a regular MapServer mode=legend call into the mapfile as a stop gap solution?

We're on 5.x Mapserver right now, not easy to upgrade real fast I'm afraid.

Thanks

bobb

So since the WMS image call goes through MapServer, we use MapServer for Legend as well.  It's looking so far like MapServer doesn't support legends entirely.  The only references I can find to cascaded WMS legends is in the TRAC listing about others having/wanting the same functionality, so far at least. . .

FYI Cascading of GetLegendGraphics has been implemented in the dev version (future 6.2). It kicks in only of some specific conditions are met. See:
