command syntax summary.
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.
This argument allows the user to explicitly specify the output
file on the command line. The default is to output to standard out.
This option applies to color displays only. It selects `XY'
format dumping instead of the default `Z' format.
This option specifies an signed value to be added to every
pixel.
This option indicates that the window manager frame should
be included when manually selecting a window.
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.
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.
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.
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.
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.
The
xwd
utility 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, and so forth. 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.
