picom-trans − an opacity setter tool
picom−trans [−w WINDOW_ID] [−n WINDOW_NAME] [−c] [−s] OPACITY
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).
−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.
• 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
