 NAME    [Toc]    [Back]
      xwd - dump an image of an X window

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

 DESCRIPTION    [Toc]    [Back]
      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    [Toc]    [Back]
      -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.

                                 Release 6.1



      -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.

      -single Only grab the primary visual for the window.  Will exploit the
              use of BackingStore by a window, if it is overlapped by
              another window, and it is available.  If the window's area
              contains multiple visuals, only the contents of the primary
              visual of the window will likely be returned.

      -multi  Grab the contents of all visuals found within the window's
              area.  Will return the contents of the window as accurately as
              possible.  Many combinations of mixed visuals will cause this
              to produce 24-bit DirectColor formatted output.  It will
              generally produce output accurately reflecting the exact
              contents of the window, as they appear on the display.  This
              is the default behavior.  The use of -single negates this
              options.

      -db     If any of the windows being processed are double-buffered
              windows, then you may find it necessary to use this option;
              this will disable some of the normal optimizations used when
              processing overlapping windows, and will guarantee that the
              contents of double-buffered windows are obtained correctly.
              This option may cause xwd to run more slowly than normal.
