Is it possible with GeoServer to have a static LegendGraphic (an
external .png/.jpg-File)? I only found that GeoServer renders its own
legend with the SLD styles.

Thanks,

Björn

Björn,
no, the legend is dynamically generated from the layer associated style.
Cheers,

Nope, at the moment you cannot. There is a pull request sitting here:
https://github.com/geoserver/geoserver/pull/63
that would add the ability to set a style wide static image to be used as
a legend.

Unfortunately the API changes were not discussed in the open, and the
patch lacks automated testing, so it cannot be applied

Cheers

I applied the patch to master and it works. What is a bit misleading
is that the LegendGraphic URL is changed (for 1.3.0), but the
GetlegendGraphic call still returns the rendered SLD-style image. And
the image doesn't get uploaded to the server.

But I shouldn't be too critical. It's a good point to start from when
I want to update this feature. Thanks for pointing it out.

Björn
