WG: [Gvsig_english] gvsig_wms_sld

[Buchholz, Robert]

 Thanks a lot to Jose and Jaume,

your reply was of help.
Just to give additional information. There is a web-based-client to Mapserver(Chameleon: Example->OGC Widgets)
http://chameleon.maptools.org/index.phtml
 that supports syling of WMS.

All the best,
Robert

No, it doesn't (at the moment). The only SLD 1.0 request implemented by gvSIG is getLegendGraphic.

I've seen that you use mapserver so you can do it. You can define two mapfiles, in the first one you must define a WMSCLIENT with several SLD legends and you must define the datasources (shapes, postgis, ...) in the second one. For example:

* wms.base (you will have to connect to this one):

LAYER
      NAME "cascade"
        DEBUG ON
      TYPE RASTER        
CONNECTION "http://localhost/cgi-bin/mapserv?map=/home/jvhigon/pruebas/wms_cascade/wms_base.map"
        CONNECTIONTYPE WMS
        METADATA
            "wms_srs"             "EPSG:23030"
            "wms_name"            "shp_polygon"
            "wms_server_version"  "1.1.1"
            "wms_format"          "image/png"
                "wms_style"        "default"
                "wms_style_default_sld"  "http://localhost/apache2-default/prueba.xml"
            "wms_style_default_legendurl_height" "20"
            "wms_style_default_legendurl_href" "http://localhost/cgi-bin/mapserv?map=/home/jvhigon/pruebas/wms_cascade/wms_base.map&REQUEST=GetLegendGraphic&SERVICE=WMS&VERSION=1.1.1&LAYER=shp_polygon&FORMAT=image/png&SLD=http://localhost/apache2-default/prueba.xml"
            "wms_style_default_legendurl_format" "image/png"
            "wms_style_default_legendurl_width"  "20"
	#you can define more styles than default !!
  END
   END # Layer

* wms_base.map (is used by the wms.map)

LAYER
      NAME "shp_polygon"
      TYPE POLYGON    		  
      DATA "shp_polygon.shp"      
      PROJECTION
         "init=epsg:23030"
      END
 [ ...]

* prueba.xml (the sld for the default style) <?xml version="1.0" encoding="UTF-8"?> <StyledLayerDescriptor version="1.0.0" > <NamedLayer>
        <Name>shp_polygon</Name>
        <UserStyle>
                <Name>default</Name>
                <FeatureTypeStyle>
                        <Rule>
                                <Name>default</Name>
                                <PolygonSymbolizer>
                                        <Fill>
                                        <CssParameter name="fill" 
>#FF0000</CssParameter>
                                        </Fill>
                                </PolygonSymbolizer>
                        </Rule>
                </FeatureTypeStyle>
</UserStyle>
</NamedLayer>

I hope it is useful for you. Best regards.
