XWUD(1) X Version 11(Release 5) XWUD(1)
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]
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(1).
-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(1) 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(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.
