DESCRIPTION
       gnome-screenshot is a GNOME  utility  for  taking  screenshots  of  the
       entire  screen,  a  window  or an user-defined area of the screen, with
       optional beautifying border effects.

OPTIONS
       -c, --clipboard
              Send the grab directly to the clipboard.

       -w, --window
              Grab the current active window instead of the entire screen.

       -a, --area
              Grab an area of the screen instead of the entire screen.

       -b, --include-border
              Include the window border within the screenshot.

       -B, --remove-border
              Remove the window border from the screenshot.

       -p, --include-pointer
              Include the pointer with the screenshot.

       -e, --border-effect=EFFECT,
              Add an effect to the outside of the screenshot  border.   EFFECT
              can  be ``shadow'' (adding drop shadow), ``border'' (adding rec‐
              tangular space around the screenshot), ``vintage'' (desaturating
              the screenshot slightly, tinting it and adding rectangular space
              around it) or ``none'' (no effect).  Default is ``none''.

       In addition, the usual GTK+ command line options apply.  See the output
       of --help for details.
