[Geoserver-users] Fwd: Dynamic url's is not working for external graphics in SLD

[Mauro B. <mau...@ge...>]

Hi Manog.
Unfortunately GetLegendGraphic doesn't support dynamic symbolizers in
ExternalGraphic hrefs.
The reason is quite simple: the legend builder doesn't have access to the
Feature data, so it wouldn't be possible for it to get a concrete value for
Ikon attribute to build an existing url for the image.
Your alternative SLD allows the legend to be drawn, because you are using
static urls.
Maybe for dynamic symbolizers we should support pre-rendered images, as
asked in http://jira.codehaus.org/browse/GEOS-3747.
