xwud - image displayer for X

   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

           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).

           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

   -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.


           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.
