[Geoserver-users] SLD for zoom-based line length

GeoServer GeoServer User

Hi,

I have a feature store with linestrings (from a shapefile). I changed the SLD to display an open arrow at one end of the line. I also managed to have different colors according to an attribute. Very well.

Now I would like to increase the length of the line according to the zoom level. I know it is possible to have the thickness vary. How about the length itself ?

Thank you.

Best regards.

The easiest way it to specify the line thickness in real world unit of
measure:
