NAME

xwd - X Window System, window image dumper. 

SYNOPSIS

xwd [ -debug ] [ -help ] [ -nobdrs ] [ -out file ] [ -xy ] [ host:display ]

DESCRIPTION

Xwd is an X Window System (protocol version 10) window image dumping utility.  Xwd allows X users to store window images in a specially formated window 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.  The window dump file format is currently under development; no guarantee of upward compatibility is made: the dump file format will be completely different under V11. 

ARGUMENT SUMMARY

-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. Monochrome displays are always dumped in ‘XY’ format. 

host:display
This  argument  allow  you  to  specify the host and display number on which to find the target window.  For example ‘xwd orpheus:1’ would specify that the target window is on display ‘1’ on the machine ‘orpheus’.  By default, xwd uses the host and display number stored in the environment variable DISPLAY, and therefore this argument is not normally specified. 

ENVIRONMENT

DISPLAY
To get default host and display number.

FILES

XWDFile.h
X Window Dump File format definition file.
