Hello, I'm trying to use a JMapPane to display some data, but I get
nothing. I haven't found a jmappane example and so I'm just guessing how to
use it, the code I've written is this :
The example is in gt-demo-mappane, but you're doing quite well. The problem
is that getDefaultStyle() doesn't actually give you a style that draws
anything by default. Its probably a bad name for the method but I guess it
made sense when we wrote it.
So if you build your self a style using some code like:
StyleFactory factory = CommonFactoryFinder.getStyleFactory(null);
FilterFactory2 ff = CommonFactoryFinder.getFilterFactory2(new Hints(
null));
Literal wellKnownName = ff.literal("circle");
org.opengis.filter.expression.Expression size = ff.literal(2);
StyleBuilder sb = new StyleBuilder();
Fill fill = factory.createFill(sb.colorExpression(Color.green));
org.opengis.filter.expression.Expression rotation = ff.literal(0);
Stroke stroke = sb.createStroke(Color.black);
Mark mark = factory.createMark(wellKnownName, stroke, fill, size,
rotation);
Graphic graphic = sb.createGraphic(null, mark, null);
Symbolizer symbolizer = sb.createPointSymbolizer(graphic);
Style[] style = new Style[1];
style[0] = sb.createStyle(symbolizer);
then you should see something.
