     DESCRIPTION
          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).

     OPTIONS
          -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(1).

          -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.  This option
                  can be used to figure out which plane to pass to
                  xpr(1) for printing.

          -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.

          -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.


     ENVIRONMENT
          DISPLAY To get default display.

     FILES
          XWDFile.h
                  X Window Dump File format definition file.

     BUGS
          xwud doesn't handle big/deep images very well on servers
          that don't have the BIG-REQUESTS extension.
