transset – Set transparency on a window
transset [-options …] [opacity]
transset is a simple program for X servers supporting the XFIXES, DAM‐
AGE, and COMPOSITE extensions. It lets the user set the transparency
on a window.
The opacity value is a number from 0 to 1, with zero being fully trans‐
parent and 1 being fully opaque. If no opacity argument is given, a
default value of 0.75 is used for the opacity value. If neither –inc
nor –dec are given, the opacity is treated as an absolute value and
set to the given opacity value. If –inc or –dec is specified, then
the opacity is treated as a relative value to increase or decrease the
current opacity by.
This option specifies the server to use; see X(7).
This option displays a help message and exits.
This option forces a toggle of opacity. If the current opacity
is not set to fully opaque (opacity 1.0), it will be reset to
fully opaque. If the window is already fully opaque, the opac‐
ity will be set normally.
This option selects the target window by waiting for the user
to click the mouse – the topmost window under the mouse cursor
when the mouse click occurs will be used as the target.
This option selects the window currently under the cursor to be
This option selects the window that currently has input focus
to be the target.
-n, –name name
This option selects the target window by name, where name is
matched as a regular expression, unless –no-regex is also
This option disables treating the name argument to –name as a
This option selects the target window by window id.
–inc This option increases the window opacity by the given opacity
–dec This option decreases the window opacity by the given opacity
-m, –min opacity
This option sets the minimum possible opacity value. It
defaults to 0 if this option is not given.
-x, –max opacity
This option sets the maximum possible opacity value. It
defaults to 1 if this option is not given.
This option prints some additional debug info as the program
