.SH "NAME"
picom-trans \- an opacity setter tool
.SH "SYNOPSIS"
.sp
\fBpicom\-trans\fR [\-w \fIWINDOW_ID\fR] [\-n \fIWINDOW_NAME\fR] [\-c] [\-s] \fIOPACITY\fR

.SH "DESCRIPTION"

.sp
\fBpicom\-trans\fR is a bash script that sets \fI_NET_WM_WINDOW_OPACITY\fR attribute of a window using standard X11 command\-line utilities, including \fBxprop\fR(1) and \fBxwininfo\fR(1)\&. It is similar to \fBtransset\fR(1) or \fBtransset\-df\fR(1)\&.

.SH "OPTIONS"



.PP
\fB\-w\fR \fIWINDOW_ID\fR
.RS 4



Specify the window id of the target window\&.

.RE
.PP
\fB\-n\fR \fIWINDOW_NAME\fR
.RS 4



Specify and try to match a window name\&.

.RE
.PP
\fB\-c\fR
.RS 4



Specify the currently active window as target\&. Only works if EWMH
\fI_NET_ACTIVE_WINDOW\fR
property exists on root window\&.

.RE
.PP
\fB\-s\fR
.RS 4



Select target window with mouse cursor\&. This is the default if no window has been specified\&.

.RE
.PP
\fB\-o\fR \fIOPACITY\fR
.RS 4



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\(cqs current opacity instead\&.
