What's the "fastest" way to take a screenshot of a specific window under Linux programatically?

La开发者_Python百科nguage doesn't matter, libraries either, I just need the fastest way specifying the window (title or handle).

Try:

import // man import for options

To take a snapshot of my pidgin client.

import -screen -window Kompislista foo.jpg // Kompislista is in swedish.

You can specify a lot of options, such as frame or window id.

see man xwd

xwd takes screen snapshots

take a look at gnome-screenshot also.

   gnome-screenshot --help

You can take the active window screen shot with -w option.
