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 con-
             nect 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 posi-
             tion 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.  Ter-
             mination 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 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 Color-
             maps.

     -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", "Pseu-
             doColor", "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

             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.
