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]

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 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.

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

ENVIRONMENT

   DISPLAY To get default host and display number.

FILES

   XWDFile.h
           X Window Dump File format definition file.
