[Mapbuilder-users] Group Layer

Mon Mar 12 02:49:49 PDT 2007

Mapscript has functions to convert from/to a Web Map Context document.

So you need to script this, you can't use a WMC directly in Mapserver CGI
AFAIK.

Look for saveMapContext and loadMapContext functions on the Map object.

Best regards,
Bart
