Hi Jody !
Happy to learn that I did not do anything wrong ! ;-)
I tried to do this :
Symbolizer s =
ptStyle.getFeatureTypeStyles()[0].getRules()[0].getSymbolizers()[0];
PointSymbolizer ps = (PointSymbolizer)s;
System.out.println("mark size = "+ ps.getGraphic().getMarks()[0].getSize());
System.out.println("fill opacity = "+
((Literal)ps.getGraphic().getMarks()[0].getFill().getOpacity()).getValue().getClass());
System.out.println("fill color = "+
ps.getGraphic().getMarks()[0].getFill().getColor());
StyleBuilder sb = new StyleBuilder();
Fill fill = sb.createFill(Color.red, 0.3);
ps.getGraphic().getMarks()[0].setFill(fill);
System.out.println("fill opacity = "+
((Literal)ps.getGraphic().getMarks()[0].getFill().getOpacity()).getValue().getClass());
in order to know type of opacity from the SLD and directly from the
StyleBuilder... And there is a difference !
In the first case (SLD), I got : class java.lang.String
In the second one (StyleBuilder), I got : class java.lang.Double
So it seems that "0.3", 0.3, 0.3f, 0.3d doesnt exactly the same. ;-)
What do you think about that ? Is there a way to fix this problem ?
