NAME
xwud - image displayer for X
SYNOPSIS
xwud [-in file] [-noclick] [-geometry geom] [-display dis-
play] [-new] [-std <maptype>] [-raw] [-vis <vis-type-or-
id>] [-scale] [-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 characteris-
tics 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 dis-
plays 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.
-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 speci-
fied: "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 (pre-
fixed 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.
