Have a look at the following code, this allows the use of custom/user
symbols.

Thanks
Andy


MapContext context = new DefaultMapContext(); 
			
StyleBuilder styleBuilder = new StyleBuilder();

ExternalGraphic icon =
styleBuilder.createExternalGraphic("FILE:///C:/temp/tutorials72.gif",
"image/gif");
			
Graphic graphic = styleBuilder.createGraphic(icon, null, null, 1, 60, 45);

PointSymbolizer pointSymbolizer=
styleBuilder.createPointSymbolizer(graphic);

Style style = styleBuilder.createStyle(pointSymbolizer);
			
Map map = (Map)ApplicationGIS.getActiveMap();
Layer layer = (Layer)map.getEditManager().getSelectedLayer();
				           
StyleBlackboard bb = (StyleBlackboard)layer.getStyleBlackboard();
bb.put(SLDContent.ID, style);

Layer writeableLayer = (Layer)layer;
writeableLayer.setStyleBlackboard(bb);
 
layer.getMap().getRenderManager().refresh(context.getAreaOfInterest());

Subject: [udig-devel] Directional Symbology


I would like to use arrow symbols to road features which has directional
properties.
I have tried this in uDIG, but it's not available,
how can we add our own symbols?, Is it possible on RC11a.
