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
- -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.
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.
