NAME

       xwud - image displayer for X


SYNOPSIS

       xwud  [-in  file] [-noclick] [-geometry geom] [-display display] [-new]
       [-std <maptype>] [-raw] [-vis <vis-type-or-id>] [-scale] [-help]  [-rv]
       [-plane number] [-fg color] [-bg color] [-dumpheader]


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(7).


       -dumpheader
               This option prints out the XWD header information only.   Noth-
               ing 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 stan-
               dard 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 applica-
               tion, 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 get-
               ting 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 speci-
               fied Standard Colormap.  The property name is obtained by  con-
               verting  the type to upper case, prepending "RGB_", and append-
               ing "_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", "Static-
               Color",  "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.
