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] [-display 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 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.

-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.
