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 &')
