Xwud is an X Window System image undumping utility. Xwud allows X
  users to display in a window an image saved in a specially formatted dump
  file, such as produced by xwd(1).
  - -bg color
- If a bitmap image (or a single plane of an image) is displayed, this
      option can be used to specify the color to display for the "0"
      bits in the image.
- -display display
- This option allows you to specify the server to connect to; see
      X(7).
- -dumpheader
- This option prints out the XWD header information only. Nothing is
      displayed.
- -fg color
- If a bitmap image (or a single plane of an image) is displayed, this
      option can be used to specify the color to display for the "1"
      bits in the image.
- -geometry geom
- This option allows you to specify the size and position of the window.
      Typically you will only want to specify the position, and let the size
      default to the actual size of the image.
- -help
- Print out a short description of the allowable options.
- -in file
- This option allows the user to explicitly specify the input file on the
      command line. If no input file is given, the standard input is
    assumed.
- -new
- This option forces creation of a new colormap for displaying the image. If
      the image characteristics happen to match those of the display, this can
      get the image on the screen faster, but at the cost of using a new
      colormap (which on most displays will cause other windows to go
      technicolor).
- -noclick
- Clicking any button in the window will terminate the application, unless
      this option is specified. Termination can always be achieved by typing
      'q', 'Q', or ctrl-c.
- -plane number
- You can select a single bit plane of the image to display with this
      option. Planes are numbered with zero being the least significant
    bit.
- -raw
- This option forces the image to be displayed with whatever color values
      happen to currently exist on the screen. This option is mostly useful when
      undumping an image back onto the same screen that the image originally
      came from, while the original windows are still on the screen, and results
      in getting the image on the screen faster.
- -rv
- If a bitmap image (or a single plane of an image) is displayed, this
      option forces the foreground and background colors to be swapped. This may
      be needed when displaying a bitmap image which has the color sense of
      pixel values "0" and "1" reversed from what they are
      on your display.
- -scale
- Allow the window to be resized, and scale the image to the size of the
      window.
- -std maptype
- This option causes the image to be displayed using the specified Standard
      Colormap. The property name is obtained by converting the type to upper
      case, prepending "RGB_", and appending "_MAP". Typical
      types are "best", "default", and "gray". See
      xstdcmap(1) for one way of creating Standard Colormaps.
- -version
- This option causes xwd to print its version information and
    exit.
- -vis vis-type-or-id
- This option allows you to specify a particular visual or visual class. The
      default is to pick the "best" one. A particular class can be
      specified: "StaticGray", "GrayScale",
      "StaticColor", "PseudoColor", "DirectColor",
      or "TrueColor". Or "Match" can be specified, meaning
      use the same class as the source image. Alternatively, an exact visual id
      (specific to the server) can be specified, either as a hexadecimal number
      (prefixed with "0x") or as a decimal number. Finally,
      "default" can be specified, meaning to use the same class as the
      colormap of the root window. Case is not significant in any of these
      strings.
  - DISPLAY
- To get default display.
  - XWDFile.h
- X Window Dump File format definition file.
xwud doesn't handle big/deep images very well on servers that don't have the
  BIG-REQUESTS extension.
