Hello,
I'd like to extend the style renderer with an implementation of
org.geotools.renderer.style.MarkFactory to paint symbols of app6a symbol
standard. The idea was to use app6a:// as a prefix for the symbol code
within a SLD document like app6a://${symbolcodeattribute} where the
attribute is taken from feature.
The implementation generates a BufferedImage for the symbol. But right now
I've no idea how to generate a shape out of it:
public class App6AMarkFactory implements MarkFactory {
public Shape getShape(Graphics2D g2, Expression symbolUrl,
Feature feature) throws Exception {
BufferedImage bi = ...
Rectangle imageRect = new Rectangle(0, 0, bi.getWidth(),
bi.getHeight());
TexturePaint imagePaint = new TexturePaint(bi, imageRect);
Shape shape = ????
return shape;
}
Do you have any suggestions? Is there any other interface to extend the
style renderer with other symbols?
Thanks a lot!
Frank
