+Screenshots
+===========
+
+With ImageMagick
+----------------
+
+The default behaviour of import is to take a custom rectangular portion
+of the screen; just launch::
+
+   import $FILENAME
+
+and drag the cursor to select the area you are interested into.
+
+To get a screenshot of the full screen (the root window)::
+
+   import -window root $FILENAME
+
+To get a screenshot of one specific window::
+
+   import -window `xwininfo | awk '/.*Window id:.*/ {print $4}'` $FILENAME
+
+and then click on the window you are interested in; to also include the
+window borders the command is::
+
+   import -border -window `xwininfo | awk '/.*Window id:.*/ {print $4}'` \
+   $FILENAME
+
+To take a screenshot of a running screensaver, login remotely to the
+computer e.g. via ssh, with the same user that is running the X session,
+and then::
+
+   DISPLAY=:0 import -window root $FILENAME
