writing JUNG graphs to images: can't reliably render complete graph

Question

I\'ve been using JUNG to visualize some simple graphs, and I\'d like to write several of them to a PNG file. Unfortunately, the images often appear to render before the graph is

Answer 1

You can also use VisualizationImageServer. It's a subtype of BasicVisualizationServer which adds a getImage method. I have had no trouble with it rendering the graphs properly.

Your code would then be like:

public void writeImage(String filename) {
    Layout layout = new CircleLayout(jungGraph);
    layout.setSize(innerSize);
    bvs = new VisualizationImageServer(layout);
    // [...]
    BufferedImage image = (BufferedImage)bvs.getImage();
}
