SYNOPSISxwud [-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
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. This option allows you to specify the server to connect to;
see X(1X). If a bitmap image (or a single plane of an image) is dis‐
played, this option can be used to specify the color to display for the
1 bits in the image. 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.
Print out a short description of the allowable options. 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. 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 techni‐
color). Clicking any button in the window will terminate the applica‐
tion, unless this option is specified. Termination can always be
achieved by typing 'q', 'Q', or ctrl-c. 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. 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. 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 val‐
ues 0 and 1 reversed from what they are on your display. 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.
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 spec‐
ified: 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
To get default display.
FILES
X Window Dump File format definition file.
