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=WINDOW_ID
           Specify the window id of the target window.

       -n, --name=WINDOW_NAME
           Specify and try to match a window name.

       -c, --current
           Specify the currently active window as target. Only works if EWMH _NET_ACTIVE_WINDOW
           property exists on root window.

       -s, --select
           Select target window with mouse cursor. This is the default if no window has been
           specified.

       -o, --opacity=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.

       -g, --get
           Print the target window’s opacity instead of setting it.

       -d, --delete
           Delete opacity of the target window instead of setting it.

       -t, --toggle
           Toggle the target window’s opacity: Set opacity if not already set, and delete if
           already set.

       -r, --reset
           Reset opacity for all windows instead of setting it.

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%:

               picom-trans -c +5

       •   Decrement opacity of current active window by 5%:

               picom-trans -c -- -5

       •   Delete current window’s opacity:

               picom-trans -c --delete

       •   Toggle current window’s opacity between 90 and unset

               picom-trans -c --toggle 90

       •   Reset all windows:

               picom-trans --reset
