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] [-silent] [-display display] [-version]

DESCRIPTION

       Xwd is an X Window System window dumping utility.  Xwd allows  X  users  to  store  window  images  in  a
       specially  formatted  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(7).

       -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 a 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.

       -silent Operate silently, i.e. don't ring any bells before and after dumping the window.

       -version
               This option indicates that xwd should print its version information and exit.

ENVIRONMENT

       DISPLAY To get default host and display number.
