Why I can not get the image file of component?

Question

Hello,
I tried to get an image file from the component. After I run the code below, there is not any new file created. Could you tell me what's wrong with it?
Rectangle d = this.getBounds();
BufferedImage bi = new BufferedImage(d.width, d.height, BufferedImage.TYPE_INT_RGB);
try {     
ByteArrayOutputStream boutstream = new ByteArrayOutputStream();
// save it to file
FileOutputStream fimage = new FileOutputStream( new File( "image.png" ) );
boutstream.writeTo(fimage);
fimage.close();}
catch (Exception ev){     
System.err.println("error making jpeg image: " + ev);
ev.printStackTrace();}

Answer 1

BufferedImage bi = new BufferedImage(d.width,d.height, BufferedImage.TYPE_INT_RGB);Straight after the above line you need to put this line:
d.paint(bi.getGraphics());
This is what was suggested to me in this thread(http://forum.java.sun.com/thread.jsp?forum=57&thread=369379) anyway, and it worked for me!
