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.  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 charac-teristics characteristics
               teristics  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 spec-ified. specified.
               ified.  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  num-bered numbered
               bered 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  fore-ground foreground
               ground  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", "Stat-icColor", "StaticColor",
               icColor", "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.
