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).
- -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(7).
- 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 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.
- -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.
- -version
- This option causes xwd to print its version information and
exit.
- -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.

xwud doesn't handle big/deep images very well on servers that
don't have the BIG-REQUESTS extension.
