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.
  - -debug
- Enable debug mode.
- -d, -display host:dpy
- 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 wdid
- 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 wdname
- 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.
  - DISPLAY
- To get default host and display number.
  - XWDFile.h
- X Window Dump File format definition file.
