[MAPSERVER-USERS] SLD ignored / External Graphic ignored

Wed Apr 9 11:59:03 EDT 2008

Christian,

  I did a quick test using you sld at 
(http://sicky.i-networx.de/temp/mapserv/test.sld) with local data 
(adapted to fit the sld : 
http://localhost/cgi-bin/mapserv.exe?map=f:/msapps/world_testdata/map/sicky.map&SERVICE=WMS&VeRsIoN=1.1.1&Request=GetMap&LAYERS=Baugrenze&BBOX=-81.366241839,42.39269586,-77.8780568047,44.13861927&SLD=http://sicky.i-networx.de/temp/mapserv/test.sld&FORMAT=png&WIDTH=400&HEIGHT=300&SRS=EPSG:4326&FORMAT=png&WIDTH=400&HEIGHT=300&STYLES=
  and I was able to render the layer Baugrenze using the styles defined 
in the sld.  So I believe there is no issue with the sld. Common error 
is usually the SLD is not accessible but you mentioned that you already 
verified that

  2nd point is that external graphics can only be of type png or gif 
(and not SVG). The reason being is that currently MapServer does not 
support SVG symbols.

    I am using Mapserver svn. If you want me to do local tests with your 
map/data, you could zip and send it to me and I will give it a try.

Best Regards,
