Xwd is
an X Window System window dumping utility. Xwd allows X users to store window
images in a specially formatted dump file. This file can then be read by
various other X utilities for redisplay, printing, editing, formatting,
archiving, image processing, etc. The target window is selected by clicking
the pointer in the desired window. The keyboard bell is rung once at the
beginning of the dump and twice when the dump is completed.
- -display
display
- This argument allows you to specify the server to connect to; see
X(7)
.
- -help
- Print out the `Usage:' command syntax summary.
- -nobdrs
- This argument
specifies that the window dump should not include the pixels that compose
the X window border. This is useful in situations where you may wish to
include the window contents in a document as an illustration.
- -out file
- This argument allows the user to explicitly specify the output file on
the command line. The default is to output to standard out.
- -xy
- This option
applies to color displays only. It selects `XY' format dumping instead of
the default `Z' format.
- -add value
- This option specifies an signed value to
be added to every pixel.
- -frame
- This option indicates that the window manager
frame should be included when manually selecting a window.
- -root
- This option
indicates that the root window should be selected for the window dump,
without requiring the user to select a window with the pointer.
- -id id
- This
option indicates that the window with the specified resource id should
be selected for the window dump, without requiring the user to select a
window with the pointer.
- -name name
- This option indicates that the window
with the specified WM_NAME property should be selected for the window dump,
without requiring the user to select a window with the pointer.
- -rect
- This
option indicates that the rectangle region of a screen should be selected
with the pointer. Window-related parameters like nobdrs and frame are ignored.
- -icmap
- Normally the colormap of the chosen window is used to obtain RGB
values. This option forces the first installed colormap of the screen to
be used instead.
- -screen
- This option indicates that the GetImage request
used to obtain the image should be done on the root window, rather than
directly on the specified window. In this way, you can obtain pieces of
other windows that overlap the specified window, and more importantly,
you can capture menus or other popups that are independent windows but
appear over the specified window.
- -silent
- Operate silently, i.e. don't ring
any bells before and after dumping the window.
- DISPLAY
- To get
default host and display number.
- XWDFile.h
- X Window Dump File format
definition file.
