NAME¶
xwd - dump an image of an X window
SYNOPSIS¶
xwd [-debug] [-help] [-nobdrs] [-out file] [-xy] [-frame] [-add
value] [-root | -id id | -name name ] [-icmap] [-screen]
[-silent] [-display display] [-version]
DESCRIPTION¶
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.
OPTIONS¶
- -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 a 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.
- -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.
- -version
- This option indicates that xwd should print its version information
and exit.
ENVIRONMENT¶
- DISPLAY
- To get default host and display number.
FILES¶
- XWDFile.h
- X Window Dump File format definition file.
