Hi list,
i would like to create an sld for lines with an symbol (flag) at the
start/endpoint of the line.
So I tried this but it's rendered the center of the graphic extent at the
start/endpoint:
<Rule>
<Name>rule1</Name>
<Title>darkgrey Line</Title>
<Abstract>A solid blue line with a 2 pixel width</Abstract>
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">#989050</CssParameter>
<CssParameter name="stroke-width">2</CssParameter>
</Stroke>
</LineSymbolizer>
<PointSymbolizer>
<Geometry>
<ogc:Function name="startPoint">
<ogc:PropertyName>CGEOM</ogc:PropertyName>
</ogc:Function>
</Geometry>
<Graphic>
<ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="flag30.svg" />
<Format>image/svg+xml</Format>
</ExternalGraphic>
<Size>20</Size>
</Graphic>
</PointSymbolizer>
<PointSymbolizer>
<Geometry>
<ogc:Function name="endPoint">
<ogc:PropertyName>CGEOM</ogc:PropertyName>
</ogc:Function>
</Geometry>
<Graphic>
<ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="flag30.svg" />
<Format>image/svg+xml</Format>
</ExternalGraphic>
<Size>20</Size>
</Graphic>
</PointSymbolizer>
</Rule>
Under the documentation [1] I've found the positioning can manipulated by an
invisible rectangle with the desired relative position for the symbols. Some
searches were not successful
Can someone help?
