Hello,
I have created an image using the Graphics2D class. I would like to be able to take the image I created and save it into a file. I have some familiarity with Input and Output streams but I can't seem to figure out make take the image and output it into a file. Any help or suggestions that are given will be greatly appreciated.
If the code of my image is necessary let me know and I will post it.
Thank You
I suspect you have a drawing on screen and you want to convert it to an Image. Have a look at the SwingUtilities.convertPointToScreen( ... ) method and the Robot.createScreenCapture( ... ) method. Both can create an Image for you. Then have a look at the ImageIO class, it can save an Image for you.Quote:

Using a Robot to capture the image is "relatively" slow. Its faster to paint the image onto a BufferedImage. The Screen Image class attempts to simplify this process.
Nice class (I always lurk at that site and your replies ;-) but reading from video memory, although way beyond or below Java's capabilities, is not necessarily slower than reading from other memory; it depends on the hardware. (I happen to know something about that). Thanks for sharing all your knowledge w.r.t. Java's Swing framework etc.Quote:

When I tested it on my machine it was much slower, so I created all the overloaded methods to try and get the best performance. I hope its not the opposite behaviour on all other machines :)Quote:
