Sorry guys if I am posting it in the wrong forum. I am trying to convert a text value (String) to an image (.jpg). My program seems to be working somewhat. It's creating a blank (whiite background) .jpg file, without my string value "Saidul Islam". I can open the file in any image editor. it just doesn't have the string I am trying to print. And the strange part is that the program is not even terminating. Here is the output I get when I run it <pre> C:\test>java Text2Image gets here flushed closed final dispose remove notify done! </pre> it's of course printing the last line but the program is not terminating. I have been working on this since yesterday. and my brain is not functioning anymore on this. So I ask for your help. what am I doing wrong and how do I get this working. Here is my program- <pre> import java.awt.*; import java.awt.image.*; import java.io.*; import com.sun.image.codec.jpeg.*;
I think I have fixed the problems you were having...
this line was causing the image you had created so far to be overwritten with a blank image of the same size...
I assume that you were trying to assign the image to the frame after you had created it... I couldn't find a direct way to paint a Graphics object or a BufferedImage object, so I simply saved the image first and then displayed it... The code I added isn't the best... there is no double buffering being done to keep the image from being erased in screen redraws, but this could be easily fixed by making a special class to display the image... I just used a regular canvas...
As far as the reason behind why your program would not exit... I think it is because you must specifically call System.exit if you are using any GUI elements... I think Java launches some kind of GUI manager that creates another thread that keeps all the GUI elements alive... so you have to specifically call System.exit...
On to the code...

Thanks Nate. It worked fine. And yes it looks like I have to use System.exit(0) to break out of the program.
