I have an editable VisualizationViewer inside a GraphZoomScrollPane. After moving and reorganizing the graph I want to save the edited version into a image file.
When I tried using VisualizationImageServer it requires the layout which removes the modifications and set up the nodes to the original layout.
By printing the JPanel into the image, I only get the visible portion and I need the full image to be saved.
I'm not an expert on Jung, but this question seems to provide a workable approach to what you want to do:
Exporting JUNG graphs to hi-res images (preferably vector based)
