## NAME

compton-trans - an opacity setter tool

## SYNOPSIS

compton-trans [-w WINDOW_ID] [-n WINDOW_NAME] [-c] [-s] OPACITY

## DESCRIPTION

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%:

      compton-trans -w "$WINDOWID" 75

- Set the opacity of the window with the name "urxvt" to 75%:

      compton-trans -n "urxvt" 75

- Set current window to opacity of 75%:

      compton-trans -c 75

- Select target window and set opacity to 75%:

      compton-trans -s 75

- Increment opacity of current active window by 5%:

      compton-trans -c +5

- Decrement opacity of current active window by 5%:

      compton-trans -c -- -5
