SYNOPSIS
xwd [-debug] [-help] [-nobdrs] [-out file] [-xy] [-frame]
[-add value] [-root | -id id | -name name ] [-icmap] [-
screen] [-display display]

DESCRIPTION
Xwd is an X Window System window dumping utility. Xwd
allows X users to store window images in a specially format-
ted dump file. This file can then be read by various other
X utilities for redisplay, printing, editing, formatting,
archiving, image processing, etc. The target window is
selected by clicking the pointer in the desired window. The
keyboard bell is rung once at the beginning of the dump and
twice when the dump is completed.

OPTIONS
-display display
This argument allows you to specify the server to
connect to; see X(1).

-help Print out the ‘Usage:’ command syntax summary.

-nobdrs This argument specifies that the window dump should
not include the pixels that compose the X window
border. This is useful in situations where you may
wish to include the window contents in a document as
an illustration.

-out file
This argument allows the user to explicitly specify
the output file on the command line. The default is
to output to standard out.

-xy This option applies to color displays only. It
selects ‘XY’ format dumping instead of the default
‘Z’ format.

-add value
This option specifies an signed value to be added to
every pixel.

-frame This option indicates that the window manager frame
should be included when manually selecting a window.

-root This option indicates that the root window should be
selected for the window dump, without requiring the
user to select a window with the pointer.

-id id This option indicates that the window with the
specified resource id should be selected for the
window dump, without requiring the user to select a
window with the pointer.

-name name
This option indicates that the window with the
specified WM_NAME property should be selected for
the window dump, without requiring the user to
select a window with the pointer.

-icmap Normally the colormap of the chosen window is used
to obtain RGB values. This option forces the first
installed colormap of the screen to be used instead.

-screen This option indicates that the GetImage request used
to obtain the image should be done on the root win-
dow, rather than directly on the specified window.
In this way, you can obtain pieces of other windows
that overlap the specified window, and more impor-
tantly, you can capture menus or other popups that
are independent windows but appear over the speci-
fied window.

ENVIRONMENT
DISPLAY To get default host and display number.
