If you have Windows 7, you probably have a 'Snipping Tool'. If not, well... Is it your own scenario? If so, you could probably program the world to draw each actor's image on the world background at the location it is currently at, on cue. Then, using BufferedImage and ImageIO, output the background to a file of 'png' type. After getting a list of all the actors, you may have to sort it, so that you draw the images behind others first.
