Hi List,
I have some polygons I want to be filled with a SVG style. The
documentation makes it clear GeoServer supports this:
http://docs.geoserver.org/stable/en/user/styling/sld-reference/pointsymbolizer.html#externalgraphic
However I'm having issues getting it to work.
- I've tried placing the SVG files onto a local web-server and accessing
them like that, but all I get in the legend is grey boxes.
- Then I placed them into /geoserver_data/styles/svgs - this resulted in a
GeoServer console error.
- Then I placed them in the styles directory itself, but I still get the
GeoServer console error.
This page (
http://docs.geoserver.org/stable/en/user/styling/sld-extensions/pointsymbols.html#external-graphics)
makes it clear that my links are correct (well, maybe not the ./svgs/ one,
but it follows convention).
My GeoServer error seems to imply it can't find the files:
07 Jan 11:22:41 ERROR [org.geoserver.ows] -
org.geoserver.platform.ServiceException: java.io.IOException
at
org.geoserver.wms.legendgraphic.GetLegendGraphicKvpReader.read(GetLegendGraphicKvpReader.java:163)
at
org.geoserver.wms.legendgraphic.GetLegendGraphicKvpReader.read(GetLegendGraphicKvpReader.java:54)
at
org.geoserver.ows.Dispatcher.parseRequestKVP(Dispatcher.java:1405)
...
And example of the applicable part of my SLD:
<se:PolygonSymbolizer>
<se:Fill>
<se:GraphicFill>
<se:Graphic>
<se:ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="
http://wppgeog3/geoserver/OSMM_SVG_symbols/boulderGeometry.svg"/>
<Format>image/svg+xml</Format>
</se:ExternalGraphic>
<se:Size>3</se:Size>
<se:Displacement>
<se:DisplacementX>3</se:DisplacementX>
<se:DisplacementY>4</se:DisplacementY>
</se:Displacement>
</se:Graphic>
</se:GraphicFill>
</se:Fill>
<VendorOption name="distance">10,10</VendorOption>
</se:PolygonSymbolizer>
This one gives me grey boxes in my legend.
----------
Other URL lines include:
<OnlineResource xlink:type="simple"
xlink:href="./svgs/boulderGeometry.svg"/>
<OnlineResource xlink:type="simple"
xlink:href="/svgs/boulderGeometry.svg"/>
<OnlineResource xlink:type="simple"
xlink:href="boulderGeometry.svg"/>
Those three give me the GeoServer error.
They also fail GeoServer validation:
"Parsing failed for ExternalGraphic: java.lang.IllegalArgumentException:
URI is not absolute"
But the documentation example includes a clearly relative URI.
<OnlineResource xlink:type="simple"
xlink:href="%GEOSERVER_DATA_DIR%/styles/svgs/rockFillSymbol.svg"/>
Fails validation with:
"Parsing failed for href: java.net.URISyntaxException: Malformed escape
pair at index 0: %GEOSERVER_DATA_DIR%/styles/svgs/boulderGeometry.svg"
----------
TL;DR: How do I make SVG Fill work with an ExternalGraphic?
Thanks,
Jonathan
