Usage

From source file:Main.java

    String imageFile = "A.jpg";
    RepaintManager.currentManager(null).setDoubleBufferingEnabled(false);
    Image image = Toolkit.getDefaultToolkit().getImage(Main.class.getResource(imageFile));
    image = image.getScaledInstance(imageWidth, imageHeight, Image.SCALE_FAST);
    JFrame frame = new JFrame("DragImage");
    frame.getContentPane().add(new Main(image));
    frame.setSize(300, 300);//from  w  w w  .  j ava2  s . co  m
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);
}

From source file:Scale.java
