display]
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
- -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.
- -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.
ENVIRONMENT
- DISPLAY
- To get default host and display number.
FILES
- XWDFile.h
- X Window Dump File format definition file.
