HI all, I have written a java application to show the images in different layouts. I am able to show it different layout correctly but some times the images are overlapped. Can you please help me, how to solve this problem. My code is given below `import javax.swing.JFrame; import java.awt.image.BufferedImage; import javax.imageio.ImageIO; import java.util.; import java.io.; import java.awt.Font; import prefuse.Constants; import prefuse.Display; import prefuse.Visualization; import prefuse.action.ActionList; import prefuse.action.RepaintAction; import prefuse.action.assignment.ColorAction; import prefuse.action.assignment.FontAction; import prefuse.action.assignment.DataColorAction; import prefuse.action.layout.graph.ForceDirectedLayout; import prefuse.action.layout.graph.; import prefuse.action.layout.; import prefuse.activity.Activity; import prefuse.controls.DragControl; import prefuse.controls.PanControl; import prefuse.controls.ZoomControl; import prefuse.data.Graph; import prefuse.data.io.DataIOException; import prefuse.data.io.GraphMLReader; import prefuse.render.DefaultRendererFactory; import prefuse.render.LabelRenderer; import prefuse.util.ColorLib; import prefuse.visual.VisualItem; import prefuse.visual.*; import prefuse.util.FontLib; import prefuse.action.assignment.DataSizeAction; import prefuse.data.*; import prefuse.render.ImageFactory; public class LayoutExample { public static void main(String[] argv) throws Exception { Graph graph = null; try { graph = new GraphMLReader().readGraph("/graphs.xml"); } catch ( DataIOException e ) { e.printStackTrace(); System.err.println("Error loading graph. Exiting..."); System.exit(1); } ImageFactory imageFactory = new ImageFactory(100,100); try { //load images and construct imageFactory. String images[] = new String[3]; images[0] = "data/images/switch.png"; images[1] = "data/images/ip_network.png"; images[2] = "data/images/router.png"; String[] names = new String[] {"Switch","Network","Router"}; BufferedImage img = null; for(int i=0; i < images.length ; i++) { try { img = ImageIO.read(new File(images[i])); imageFactory.addImage(names[i],img); } catch (IOException e){ } } } catch(Exception exp) { } Visualization vis = new Visualization(); vis.add("graph", graph); LabelRenderer nodeRenderer = new LabelRenderer("name", "type"); nodeRenderer.setVerticalAlignment(Constants.BOTTOM); nodeRenderer.setHorizontalPadding(0); nodeRenderer.setVerticalPadding(0); nodeRenderer.setImagePosition(Constants.TOP); nodeRenderer.setMaxImageDimensions(100,100); DefaultRendererFactory drf = new DefaultRendererFactory(); drf.setDefaultRenderer(nodeRenderer); vis.setRendererFactory(drf); ColorAction nText = new ColorAction("graph.nodes", VisualItem.TEXTCOLOR); nText.setDefaultColor(ColorLib.gray(100)); ColorAction nEdges = new ColorAction("graph.edges", VisualItem.STROKECOLOR); nEdges.setDefaultColor(ColorLib.gray(100)); // bundle the color actions ActionList draw = new ActionList(); //MAD - changing the size of the nodes dependent on the weight of the people final DataSizeAction dsa = new DataSizeAction("graph.nodes","size"); draw.add(dsa); draw.add(nText); draw.add(new FontAction("graph.nodes", FontLib.getFont("Tahoma",Font.BOLD, 12))); draw.add(nEdges); vis.putAction("draw", draw); ActionList layout = new ActionList(Activity.DEFAULT_STEP_TIME); BalloonTreeLayout balloonlayout = new BalloonTreeLayout("graph",50); layout.add(balloonlayout); Display d = new Display(vis); vis.putAction("layout", layout); // start up the animated layout vis.run("draw"); vis.run("layout"); d.addControlListener(new DragControl()); // pan with left-click drag on background d.addControlListener(new PanControl()); // zoom with right-click drag d.addControlListener(new ZoomControl()); // -- 6. launch the visualization ------------------------------------- // create a new window to hold the visualization JFrame frame = new JFrame("prefuse example"); // ensure application exits when window is closed frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(d); frame.pack(); // layout components in window frame.setVisible(true); // show the window } } ` Can anyone please let me know how to customize the image sizes / renders insuch way that images won't overlapped.
