title: Set transparent background of the taken Snapshot
body: <p>I use the <code>snapshot()</code> method on the <code>Shape</code> object in order to convert it into <code>ImageView</code> and nest it into <code>Label</code>. The problem is, that when I take a snapshot of the <code>Shape</code> object it is closed into square field with white background. Is there a way to make it transparent? I use the code below in order to convert given <code>Shape</code> into an <code>ImageView</code> object:</p>
  
  <pre><code>WritableImage snapshot = Shape.snapshot(new SnapshotParameters(), null);
  ImageView imageView = new ImageView(snapshot);
  Label label = new Label();
  label.setGraphic(imageView);
  Pane.getChildren().add(label);
  </code></pre>
