Hi all,
It looks like this is not possible since PointSymbolizer should render on the centre point of a geometry and LineSymbolizer appears to have no capability to show only the nodes. Looks like I’m going to have to try to extract the nodes into a seperate layer at the database level and then render that layer as a point dataset.
If anyone has a better solution please let me know, cheers.
I’ve been having a little look at this - I thought perhaps you could cheat and use the stroke-linejoin and stroke-linecap CssParameters to place points on the nodes, whilst using a stroke-width of zero. However now it seems stroke-linejoin and stroke-linecap are being completely ignored, at least in 1.6 trunk as of a week ago. I tried with linestrings and polygons with no success, but I remember they were working some time ago.
I attached an SLD if anyone wants to verify it - heres the request:
http://localhost/geoserver/wms?bbox=-180,-90,180,90&SLD=http://localhost/test.sld&Format=image/png&request=GetMap&width=250&height=250

Those params were definitely working on 1.5.x? That's odd, I don't think there were many changes in SLD stuff between 1.5 and 1.6.

Hi Miles,
Verified... this request does not work on 1.6.x.. Scheduling a jira for it.
http://jira.codehaus.org/browse/GEOS-1252
Thanks for the bug report!!

If the stroke-width is 0, then the linecap and linejoin should have
no effect whatsoever... am I missing something?
