how to use different shapes for jung shape transform

Question

I'm using jung library to draw my grap, so I was wondering if there is any way to create vertex in a different shape rather than creating an ellipse. For instance, I want octagon. This is how I set the shape:

    Transformer<String,Shape> vertexSize = new Transformer<String,Shape>(){

    @Override
    public Shape transform(String str) {
        Ellipse2D circle = new Ellipse2D.Double(-5, -5, 10, 10);
        if(drugnames.contains(str)){
            return AffineTransform.getScaleInstance(3,3).createTransformedShape(circle);
        }
        else{
            return AffineTransform.getScaleInstance(1,1).createTransformedShape(circle);
        }

        // TODO Auto-generated method stub
    }
};

Answer 1

VisualizationViewer.getRenderContext().setVertexShapeTransformer(vst)

where vst is a Transformer<V, Shape> .

AbstractVertexShapeTransformer can do a lot of the heavy lifting for you.

See PluggableRendererDemo for examples of these things in action (source is part of the distribution).
