E.   type source code below into tab source ClassUtilitas.java
 
package efeklabelicon;

import java.awt.AlphaComposite;

import java.awt.Color;

import java.awt.GradientPaint;

import java.awt.Graphics2D;

import java.awt.Image;

import java.awt.image.BufferedImage;

 

/**

 */ // MASUNDUH II

public class ClassUtilitas {

   

     public static final BufferedImage convertToBufferedGambar(Image sumber)

  {

    int width = sumber.getWidth(null);

    int height = sumber.getHeight(null);

    BufferedImage destinasi = new BufferedImage(width, height, 2);

 

    Graphics2D g2 = (Graphics2D)destinasi.getGraphics();

    g2.drawImage(sumber, 0, 0, null);

    g2.dispose();

 

    return destinasi;

  }

 

    public static final BufferedImage convertToBufferedGambarRefleksi(BufferedImage sumber){

 

        BufferedImage destinasi = new BufferedImage(sumber.getWidth(),

sumber.getHeight() + sumber.getHeight()/2,2);

       

        Graphics2D g2d = (Graphics2D) destinasi.getGraphics();

        g2d.drawImage(sumber, 0, 0,null);

        g2d.scale(1.0D, -1.0D);

        g2d.drawImage(sumber, 0, -sumber.getHeight()*2,null);

        g2d.scale(1.0D, -1.0D);

        g2d.translate(0, sumber.getHeight());

        g2d.setPaint(new GradientPaint(0.0F, 0.0F, new Color(1.0F, 1.0F, 1.0F, 0.3F),

0.0F, sumber.getHeight()/2,new Color(1.0F, 1.0F, 1.0F,0.0F)));

       

        g2d.setComposite(AlphaComposite.DstIn);

        g2d.fillRect(0, 0, sumber.getWidth(), sumber.getHeight());

        g2d.dispose();

       

        return destinasi;

    }

    public static final BufferedImage

convertToBufferedGambarRefleksi(Image sumber)

  {

    return convertToBufferedGambarRefleksi

(convertToBufferedGambar(sumber));

  }

}

 



F.   and retype source code below  into Class LabelEfek.java
 
package efeklabelicon;

import java.awt.image.BufferedImage;

import javax.swing.Icon;

import javax.swing.ImageIcon;

import javax.swing.JLabel;

/**

 * @author CodeMaster

 */ // MASUNDUH II

public class LabelEfek extends JLabel{

   

    private Icon IkonRefleksi;

   

     public LabelEfek()

  {

    setIkonRefleksi(null);

  }

    public Icon getIkonRefleksi() {

        return IkonRefleksi;

    }

    public void setIkonRefleksi(Icon IkonRefleksi)

throws IllegalArgumentException {

 if (IkonRefleksi == null) {

      firePropertyChange("IkonRefleksi", getIkonRefleksi(), IkonRefleksi);

      this.IkonRefleksi = IkonRefleksi;

      setIcon(null);

    } else {

      if (!(IkonRefleksi instanceof ImageIcon)) {

        throw new IllegalArgumentException();

      }

      firePropertyChange("IkonRefleksi",getIkonRefleksi(), IkonRefleksi);

      this.IkonRefleksi = IkonRefleksi;

      BufferedImage image = ClassUtilitas.convertToBufferedGambarRefleksi

        (((ImageIcon)IkonRefleksi).getImage());

      setIcon(new ImageIcon(image));

    }       

    }

   

}
