in-memory image creation, using Java Application, creating dynamic icon image

Home >> Java
Have you ever thought of creating image using programmatically?
By using/controlling R, G, B values for getting any color on
screen.
Working with RGB (Red,Green, Blue) to create Image that is created
by setting R, G, B value in a array bits.

By creating ColorModel and changing image bits to MemoryImageSource
for creating an image in memory and displaying this on Applet or
an application using Java AWT.

Following section will be showing all the steps I followed to 
achieve this objective.











Steps includes:
1. creating a ColorModel as follows:

 ColorModel colorModel=ColorModel.getRGBdefault();
2. Creating values of different colors such as red, green,
 red, white, black.

 int r=new Color(255,0,0).getRGB();
 int g=new Color(0,255,0).getRGB();
 int b=new Color(0,0,255).getRGB();
 int w=new Color(255,255,255).getRGB();
 int bl=new Color(0,0,0).getRGB();

3. Creating the image bits in an array as follows:

 int[] imageBits = new int[] {
 w,w,w,w,w,w,w,w,w,w,w,w,w,
 w,w,w,w,w,w,w,w,w,w,w,w,w,
 w,w,w,w,b,b,b,b,b,w,w,w,w,
 w,w,w,w,b,b,b,b,b,w,w,w,w,
 w,w,w,w,b,b,b,b,b,w,w,w,w,
 w,w,g,g,g,g,b,b,b,w,w,w,w,
 w,w,g,g,g,g,b,b,b,w,w,w,w,
 w,w,g,g,g,g,w,w,w,w,w,w,w,
 r,r,g,g,g,g,w,w,w,w,w,w,w,
 r,r,r,w,w,w,w,w,w,w,w,w,w,
 r,r,r,w,w,w,w,w,w,w,w,w,w,
 w,w,w,w,w,w,w,w,w,w,w,w,w,
 w,w,w,w,w,w,w,w,w,w,w,w,w,
 };

4. Creating MemoryImageSource by passing ColorModel
 and imageBits as,

 MemoryImageSource mis = new MemoryImageSource
			 (13,12,colorModel,imageBits, 0,13);
5. creating Image by using MemoryImageSource.

 img = createImage(mis);

6. Displaying this image on Applet

	public void paint(Graphics g)
	{
		g.drawImage(img,10,10,40,40,this);
	}
	

If you want to have this dynamic image created with a Java example
then I have the complete source as follows:

In the below source code, I am trying to achieve a graphical icon
as shown in this Image 

CreateDynamicImage.java

public class CreateDynamicImage {
  public CreateDynamicImage() {
    try {

			  };
	  MemoryImageSource mis = new MemoryImageSource
		 (14,13,colorModel,imageBits, 0,14);
	  Frame frm = new Frame();
      Image img = Toolkit.getDefaultToolkit().createImage(mis);
      frm.setIconImage(img);
      frm.show();
      frm.addWindowListener(new WindowAdapter() {
    	public void windowClosing(WindowEvent we) {
    		System.exit(0);
    		
    	}});
	} catch (Exception ex) {
	  ex.printStackTrace();
	}
  }
  private Image createImage(MemoryImageSource mis) {
	// TODO Auto-generated method stub
	return null;
}
public static void main(String args[]) {
    new CreateDynamicImage();
  }
}

After compilation of this code, one can run it to see the dynamic
image created and shown as icon on the Frame header/title.
