Re: [Geoserver-users] SLD Rotate a symbol basen on a expression with geom and a constant

[Frank G. <fg...@us...>]

Hmm, just copied from the wrong editor, but here we go :

<PointSymbolizer>
            <Geometry>
              <ogc:Function name="startPoint">
                <ogc:PropertyName>the_geom</ogc:PropertyName>
              </ogc:Function>
            </Geometry>
           <Graphic>
              <Mark>
                <WellKnownName>shape://oarrow</WellKnownName>
                <Fill/>
                <Stroke>
                  <CssParameter name="stroke">#000000</CssParameter>
                </Stroke>
              </Mark>
              <Size>20</Size>
              <Rotation>
                <ogc:Add>
                  <ogc:Function name="startAngle">
                    <ogc:PropertyName>the_geom</ogc:PropertyName>
                  </ogc:Function>
                  <ogc:Literal>180.0</ogc:Literal>
                </ogc:Add>
              </Rotation>
            </Graphic>
          </PointSymbolizer>

Hope that's what you expected ;)
