Make screenshot of window in focus without window`s decorations

Question

I have to make an screenshot of active window's content (without window's decorations). I decided to use imagemagick and I know how to make screenshot of whole screen, but it i'snt what I need.

It also possible to use other programs, I appreciate imagemagick because it will be used in this script anyway.

Thank you for responding!

import , the screen-shooting tool that comes with ImageMagick, takes a -window flag that lets you choose the window you want to capture, either by its ID or name. It doesn't capture the window border by default. (If you change your mind and decide that you do want to include it, also pass the -frame flag.)

You can then use xdotool to find out the ID of the currently focused window, like so:

import -window "$(xdotool getwindowfocus -f)" /tmp/file.png
