getLegendGraphic: support of pre-rendered images
------------------------------------------------
Key: GEOS-3747
URL: http://jira.codehaus.org/browse/GEOS-3747
Project: GeoServer
Issue Type: Improvement
Components: WMS
Affects Versions: 2.0.0
Environment: Intel Core i5, Windows XP SP3
Reporter: Frank
Assignee: Andrea Aime
Priority: Minor
Attachments: legendgraphic.patch
It might be a good idea to enable a user to specify a pre-rendered image file as legend graphic, especially for raster data.
In the SLD-Definition, a user can already set up such a graphic file with the element <LegendGraphic>, but this element is currently not interpreted by geoserver.
Attached is a patch for a (very basic) version, which interprets the element <LegendGraphic> and delivers the file given in <Graphic> -> <ExternalGraphic> -> <OnlineResource>.
