An alternative I prefer is scrot. I've used it with TIFF and JPEG, but generally prefer PNG. The killer feature that I haven't found in other methods is the delay. This makes it simple to capture a window while you're in the process of, say, opening a menu. A tiny example attached. I drive it with fvwm's buttons, with commands like *MyButtons: (2x1+2+1, Title 'Delay 10', Icon xterm.xpm, Action 'Exec exec myfvwm-scrot-png-delayed.sh &') Cheers, David.
