Re: [udig-devel] What glyph is this? Hi Moovida

[Andrea Antonello <andrea.antonello@xxxxxxxxx>]

I gave a quick look on how WMS deals with this... and it uses the
generateDefaultIcon only to create the icon in the layer view. It
doesn't even care about the legend, which is empty when activated only
with a WMS layer.
This is probably due to the fact that it contains only the color
information of the image and doesn't know much about the real values of
the maps.

I'll have a look at the legend. But it is drained with SLD style stuff
and I get lost in that one...
