*compton-trans* is a bash script that sets '_NET_WM_WINDOW_OPACITY' attribute of a window using standard X11 command-line utilities, including *xprop*(1) and *xwininfo*(1). It is similar to *transset*(1) or *transset-df*(1).
OPTIONS
-------
*-w* 'WINDOW_ID'::
Specify the window id of the target window.
*-n* 'WINDOW_NAME'::
Specify and try to match a window name.
*-c*::
Specify the currently active window as target. Only works if EWMH '_NET_ACTIVE_WINDOW' property exists on root window.
*-s*::
Select target window with mouse cursor. This is the default if no window has been specified.
*-o* 'OPACITY'::
Specify the new opacity value for the window. This value can be anywhere from 1-100. If it is prefixed with a plus or minus (+/-), this will increment or decrement from the target window's current opacity instead.
EXAMPLES
--------
* Set the opacity of the window with specific window ID to 75%:
