NAME
xwd - dump an image of an X window

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 for-
matted dump file. This file can then be read by various
other X utilities for redisplay, printing, editing, for-
matting, 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 spec-
ify 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 window, rather than directly on the specified
window. In this way, you can obtain pieces of
other windows that overlap the specified window,
and more importantly, you can capture menus or
other popups that are independent windows but
appear over the specified window.

ENVIRONMENT
DISPLAY To get default host and display number.
