Hi all,
I am trying to render an external graphic (which works out fine). Now I also
want to apply a displacement to move it a bit to the right.
Unfortunately the image stays where it is and does not seem to move a bit. It
does not seem to make a difference whether I put in values for displacement or
Anchorpoint.
Here's my code and the resulting sld:
FilterFactory filterFactory = CommonFactoryFinder.getFilterFactory();
StyleBuilder sb = new StyleBuilder();
Graphic graphic = sb.createGraphic();
URL url = getClass().getClassLoader().getResource("image.png");
ExternalGraphic external = sb.createExternalGraphic( url, "image/png");
graphic.graphicalSymbols().clear();
graphic.graphicalSymbols().add( external );
graphic.setSize(filterFactory.literal(85));
graphic.setDisplacement(sb.createDisplacement(50, 50)); // displacement is
measured in pixels
PointSymbolizer pointSymbolizer = styleFactory.createPointSymbolizer(graphic,
null);
pointSymbolizer.getOptions().put("maxDisplacement", "150");
rule.symbolizers().add(pointSymbolizer);
<?xml version="1.0" encoding="UTF-8"?>
<sld:Graphic xmlns="http://www.opengis.net/sld";
xmlns:sld="http://www.opengis.net/sld"; xmlns:ogc="http://www.opengis.net/ogc";
xmlns:gml="http://www.opengis.net/gml";>
<sld:ExternalGraphic>
<sld:OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink";
xlink:type="simple" xlink:href="file:/path/to/image.png"/>
<sld:Format>image/png</sld:Format>
</sld:ExternalGraphic>
<sld:Size>85</sld:Size>
<sld:Displacement>
<sld:DisplacementX>50.0</sld:DisplacementX>
<sld:DisplacementY>50.0</sld:DisplacementY>
</sld:Displacement>
</sld:Graphic>
Am I missing something here?
