Hi, everyone,
I've been struggling to get label working with a polygon shapefile (pt/line
works fine). Basically polygon draws fine without any label. Here is my
code, could anyone please help? Thanks a bunch.
private Style getPolygonLabelStyle(){
StyleBuilder sb = new StyleBuilder();
StyleFactory styleFactory = sb.getStyleFactory();
//LinePlacement linePlacement = sb.createLinePlacement(10);
float[] f = {0.5f};
Stroke stroke =
styleFactory.createStroke(sb.colorExpression(Color.BLACK),
sb.literalExpression(2),
sb.literalExpression(1),
sb.attributeExpression(sb.LINE_JOIN_ROUND),
sb.attributeExpression(sb.LINE_CAP_ROUND),
f, sb.literalExpression(3), null, null);
Fill fill =
styleFactory.createFill(sb.colorExpression(Color.YELLOW),
sb.literalExpression(0.7));
PolygonSymbolizer ploygonSymbolizer =
styleFactory.createPolygonSymbolizer(stroke, fill, null);
TextSymbolizer textSymbolizer =
sb.createTextSymbolizer(sb.createFill(Color.BLACK),
new org.geotools.styling.Font[] { sb.createFont("Arial",12),
sb.createFont("Arial", 10) },
sb.createHalo(Color.WHITE, 1, 2),
sb.literalExpression("hello world"), null, "Shape");
Style polygonStyle = sb.createStyle(ploygonSymbolizer);
polygonStyle.addFeatureTypeStyle(sb.createFeatureTypeStyle(null,
sb.createRule(textSymbolizer)));
return polygonStyle;
}
