Hi list,
i’m trying to bind an external graphic to use in SLD, but it doesn’t work. Here’s a snippet:
---------------------------------8<----------------------------------------------
GIF
3
---------------------------------8<----------------------------------------------
the bitmap is reacheable for geoserver. I inserted the url http://localhost:9080/geoserver/bitmaps/red_cross.GIF in the browser and got the bitmap back.
The SLD also looks OK. I get no error in the log. Only these areas which are styled with above PolygonSymbolizer are white. ExternalGraphic is surely implemented for PolygonSymbolizer isn’t it?

Hi Albrecht,
Which version of GeoServer are you using? I was under the impression that this should work ok in more recent versions.

Hum, yes, but nothing is able to support the mime type "GIF". Try with
"image/gif", you should have better chance.

Yep, you're right, that was wrong. Unfortunately it seemed not to be the origin of the problem. I also tried to place the bitmap somewhere else on an apache web-directory; i tried with png instead of gif - nothing worked.
I'm helpless :o/
Best wishes
Albrecht

Albrecht, I think you simply have a typo:
OnlineRessource - too many "s" in there - should be OnlineResource
Also, I've found that the value of Size should match the value of the
image's height for best results.
Otherwise, it can get stretched or squished or be too small. You might want
to check that just in case.
I have some working examples at these URLs if you're interested:
