Yves,

Yes to all your questions. At least when I access a CubeWerx WMS service.

Cheers,

Brad

Hi list,

Sorry to use a post from another person but I checked the source code
from the link below, and I have some question about it.

Does OL could use SLD service for rendering a WMS layer?

Does it allow me to render a WMS layer with different Opacity (change
opacity on the fly as well) for "non base layer"?

regards,

Y.
