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(7).
-dumpheader
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.
-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.
display
To get default display.
environment
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.
