16. 52. 12. Create an image that supports transparent pixels from GraphicsConfiguration


import java.awt.GraphicsConfiguration;

import java.awt.GraphicsDevice;

import java.awt.GraphicsEnvironment;

import java.awt.Transparency;

import java.awt.image.BufferedImage;



public class Main {

  public static void main(String[] argv) throws Exception {

    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();

    GraphicsDevice gs = ge.getDefaultScreenDevice();

    GraphicsConfiguration gc = gs.getDefaultConfiguration();



    BufferedImage bimage = gc.createCompatibleImage(100, 100, Transparency.BITMASK);



  }

}
