NAME
----
picom-trans - an opacity setter tool

SYNOPSIS
--------

*picom-trans* [-w 'WINDOW_ID'] [-n 'WINDOW_NAME'] [-c] [-s] 'OPACITY'

DESCRIPTION
-----------

*picom-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%:
+
------------
picom-trans -w "$WINDOWID" 75
------------

* Set the opacity of the window with the name "urxvt" to 75%:
+
------------
picom-trans -n "urxvt" 75
------------

* Set current window to opacity of 75%:
+
------------
picom-trans -c 75
------------

* Select target window and set opacity to 75%:
+
------------
picom-trans -s 75
------------

* Increment opacity of current active window by 5%:
