Hi folks,
>From the geotools user guide Styling features for display <https://docs.geotools.org/latest/userguide/library/render/style.html> - GeoTools 27-SNAPSHOT User Guide example: // // create the graphical mark used to represent a city Stroke stroke = sf.stroke(ff.literal("#000000"), null, null, null, null, null, null); Fill fill = sf.fill(null, ff.literal(Color.BLUE), ff.literal(1.0)); // OnLineResource implemented by gt-metadata - so no factory! OnLineResourceImpl svg = new OnLineResourceImpl(new URI("file:city.svg")); svg.freeze(); // freeze to prevent modification at runtime OnLineResourceImpl png = new OnLineResourceImpl(new URI("file:city.png")); png.freeze(); // freeze to prevent modification at runtime // // List of symbols is considered in order with the rendering engine choosing // the first one it can handle. Allowing for svg, png, mark order List<GraphicalSymbol> symbols = new ArrayList<>(); symbols.add(sf.externalGraphic(svg, "svg", null)); // svg preferred symbols.add(sf.externalGraphic(png, "png", null)); // png preferred symbols.add(sf.mark(ff.literal("circle"), fill, stroke)); // simple circle backup plan Expression opacity = null; // use default Expression size = ff.literal(10); Expression rotation = null; // use default AnchorPoint anchor = null; // use default Displacement displacement = null; // use default // define a point symbolizer of a small circle Graphic circle = sf.graphic(symbols, opacity, size, rotation, anchor, displacement); PointSymbolizer pointSymbolizer = sf.pointSymbolizer("point", ff.property("the_geom"), null, null, circle); Would it be possible to specify the SVG graphic dynamically using "Expression" ? I would like the SVG to be specified via ff.property() ? Appreciate your help.
