JAI blank image/graphics

Question

Hello,
I'm using JAI because I do not want to call awt classes because they need my X-server running...
All I want to do is creating a blank/new image-like thing and get it's graphics, all I seem to be able to find is how to create image-like objects with an existing picture in it...
Anybody a clue on how to create a blank image without having to load an existing pic from anywere??
Thnx

<code>
import java.awt.*;
import java.awt.image.*;
public class jwmem extends java.awt.Frame {
Image i;
int width = 200;
int height = 200;
public jwmem () {
int[] pixels = new int [width*height];
int c;
double radianConversion = Math.PI / 180.0;
for (int index=0,y=0;y<height;y++) {
c = ((0xff) &
(byte)(Math.abs (Math.sin((y+height)*radianConversion))* 255));
for (int x=0;x<width;x++) {
pixels[index++] = ((0xff<<24) | (c<<16) | (c<<8) | c);
i = createImage (new MemoryImageSource (width, height, pixels, 0, width));
setFont (new Font ("TimesRoman", Font.BOLD | Font.ITALIC, 32));
setSize(100,100);
show();
     public static void main(String args[]) {
          new jwmem();
public void paint (Graphics g) {
g.drawImage (i, 0, 0, this);
g.drawString ("JavaWorld", 30, 80);

this is a code to create a new image using awt

go to this link for getting code using applet
I cant get one thing both the codes wont need any server to be running.
for applet you need a html file having content
<applet code=jwmem.class height=100 width=100>this browser wont supports applet</applet>
you need to put the .class file and html file in one directory thats all.
Hope this is the one you need
