xwd - dump an image of an X window

SYNOPSIS

xwd [-debug] [-help] [-nobdrs] [-out file] [-xy] [-frame] [-display display] [-add value] [-root] [-name window_name] [-id window_id]

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 mouse 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(1). 

-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 selects the root window as the window to dump.
