xwd - dump an image of an X window
xwd [-debug] [-help] [-nobdrs] [-out file] [-xy] [-frame] [-add value]
[-root | -id id | -name name ] [-icmap] [-screen] [-silent] [-display
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 win-
dow 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.
This argument allows you to specify the server to connect to;
-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.
This argument allows the user to explicitly specify the output
file on the command line. The default is to output to standard
-xy 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
-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.
This option indicates that the window with the specified
WM_NAME property should be selected for the window dump, with-
out requiring the user to select a window with the pointer.
-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.
X Window Dump File format definition file.
