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 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.

       -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.
