Node label icons

It is possible to add an icon to a node label with one of the following methods:

• NodeLabel.setIcon(BufferedImage) to use a an image
• NodeLabel.setIcon(File) to use a File
• NodeLabel.setIcon(URL) to use an URL

Additional methods allow to set the scale of the image representation on the node:

• The NodeLabel.setIconScaleX(float) to set the X scale fo the image
• The NodeLabel.setIconScaleY(float) to set the Y scale fo the image
• The NodeLabel.keepIconAspectRatio(boolean) to specify if the aspect ratio of the image must be kept

Example

The following code sets the icon on a node label:

      GraphMLFactory factory = GraphMLFactory.getInstance();
      GraphMLDiagram diagram = factory.newDiagram();
   
      GraphMLNode node = diagram.addNode();
      node.setHasFillColor(false);
      node.setHasBorderColor(false);   
   
      NodeLabel label = node.setLabel("The Label");
      label.setVerticalTextPosition(LabelStyle.VERTICALPOS_BOTTOM);
   
      File iconFile = context.getPath("hand.png");   
      label.setIcon(iconFile);
      label.setIconScaleX(0.2f);
      label.setIconScaleY(0.2f);

The result is:
