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)
.
- -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.
- XWDFile.h
- X Window Dump File format definition
file.
xwud doesn't handle big/deep images very well on servers that don't
have the BIG-REQUESTS extension.
