import java.awt.event.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;
import javax.swing.*;

    static Javamark102 soho= new Javamark102();
    static JFileChooser save;
    static JFileChooser open;

            public static void main(String args[]){
                    if(rem==null){
                        rem=new JFrame("Shades");
                    };

                  rem.setSize(500,500);
                  rem.setLocation(1,1);
                  rem.setContentPane(soho);
                  rem.setVisible(true);

                  open();
                 // save();

    };
