NAME

  xwud - image displayer for X


SYNOPSIS

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


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(1X).

  -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.
      This option can be used to figure out which plane to pass to xpr(1X)
      for printing.

  -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.

  -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(1X) 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.


DESCRIPTION

  The xwud program 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(1X).


ENVIRONMENT

  DISPLAY To get default display.


FILES

  <XWDFile.h>
      X Window Dump File format definition file.


SEE ALSO

  xwd(1X), xpr(1X), xstdcmap(1X), X(1X)
