示例1: autoZoomViewer
import edu.uci.ics.jung.visualization.transform.MutableTransformer; //導入方法依賴的package包/類
public static void autoZoomViewer(VisualizationViewer<?, ?> vv,
LayerViewer<?, ?> home, Directions direction) {
if (vv == null || home == null)
return;
// reset transforms
MutableTransformer layoutTrans = vv.getRenderContext()
.getMultiLayerTransformer()
.getTransformer(edu.uci.ics.jung.visualization.Layer.LAYOUT);
layoutTrans.setToIdentity();
MutableTransformer viewTrans = vv.getRenderContext()
.getMultiLayerTransformer()
.getTransformer(edu.uci.ics.jung.visualization.Layer.VIEW);
viewTrans.setToIdentity();
Dimension dim = vv.getSize();
Rectangle2D.Double graphBounds = home.getGraphBoundsCache();
CrossoverScalingControl scaler = new CrossoverScalingControl();
// Scale using crossover scaler, so vertices will not grow
// larger than they are in original
double factor = Double.POSITIVE_INFINITY;
if (direction == Directions.HORIZONTAL || direction == Directions.BOTH)
factor = dim.getWidth() / graphBounds.width;
if (direction == Directions.VERTICAL || direction == Directions.BOTH
