[mapserver-users] Union Layers and GetLegendGraphic

[Keith Moss]

Hi Tamas,
 
The notion we had was that a GetLegendGraphic on a union layer would just work in the same way as a GetLegendGraphic on a layer group does at the moment. i.e. Displays all of the classes for all of the source layers.
 
cheers

Keith,

The idea looks promising. Which source layer should be used to copy the styles?
In case if the source layer contains multiple classes (with expressions, classitem etc.), the actual feature may be required to select the class to be used.

Best regards,

Tamas

	Hi all,
	 
	Just noticed an issue with the new 'UNION' layer type in MapServer 6.
	 
	With 'STYLEITEM AUTO' set the styles are inherited for GetMap requests but, it seems, not for GetLegendGraphic requests. Giving the UNION layer a copy of the styles for the source layers works, but obviously this is exactly ideal. Just wondering if this is on anyone's "to implement" list?
	 
	cheers
