X window ==> Postscript

XtoPS is an X Window System window dumping utility. XtoPS reads an
image from any visible window on an X server and outputs it to
encapsulated Postscript file. You can view this file with any
Postscript compatible viewer or printer. The image is displayed in
color on viewers or printers that support color Postscript,
otherwise it is displayed as grayscale. The target window can be
specified by id or name or be 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.

In addition to XtoPS, ImageMagick, an X11 image processing and
display utility is available on expo.lcs.mit.edu as
contrib/ImageMagick.tar.Z. Included are these programs:
X
Display
X
X Display is a machine architecture independent image processing and
X display program. It can display any image in the MIFF format on
X any workstation display running an X server. Display first
X determines the hardware capabilities of the workstation. If the
X number of unique colors in the image is less than or equal to the
X number the workstation can support, the image is displayed in an X
X window. Otherwise the number of colors in the image is first
X reduced to match the color resolution of the workstation before it
X is displayed.
X
X This means that a continuous-tone 24 bits/pixel image can display
X on a 8 bit pseudo-color device or monochrome device. In most
X instances the reduced color image closely resembles the original.
X Alternatively, a monochrome or pseudo-color image can display on a
X continuous-tone 24 bits/pixels device.
X
Import
X
X Import is an X Window System window dumping utility. Import allows
X X users to store window images in a specially formatted dump file.
X This file can then be read by the Display utility for redisplay,
X printing, editing, formatting, archiving, image processing, etc.
X The target window can be specified by id or name or be selected by
X clicking the mouse in the desired window. The keyboard bell is
X rung once at the beginning of the dump and twice when the dump is
X completed.

.TH XtoPS 1 "4 July 1990" "X Version 11"
.SH NAME
XXtoPS - dump an image of an X window as encapsulated Postscript
.SH SYNOPSIS
.B "XtoPS"
[ \fIoptions\fP ... ] \fIfile\fP
.SH DESCRIPTION
.PP
.I XtoPS
is an X Window System window dumping utility.
.I XtoPS
reads an image from any visible window on an X server and outputs it to
an encapsulated Postscript file. You can view this file with any
Postscript compatible viewer or printer. The image is displayed in
color on viewers or printers that support color Postscript, otherwise
it is displayed as grayscale.
.pp
The target window can be specified by id or name or be 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.
.SH EXAMPLE
.PP
To save the entire X server screen as encapsulated Postscript in a file on
disk titled root.ps, use:
.PP
X XtoPS -root root.ps
.SH OPTIONS
\fIXtoPS\fP options can appear on the command line or in your X resources
file (see X(1)). Options on the command line supercede values specified
in your X resources file.
.TP 4
.B "-border"
include image borders in the output image.
.TP 4
.B "-display \fIhost:display[.screen]\fP"
specifies the X server to contact; see \fBX(1)\fP.
.TP 4
.B "-frame"
include window manager frame.
.TP 4
.B "-id \fIvalue\fP"
select window with this id.
.TP 4
.B "-name \fIname\fP"
select window with this name.
.TP 4
.B "-root"
select root window.
.PP
Change \fI-\fP to \fI+\fP in any option above to reverse its effect. For
example \fB+frame\fP means do not include window manager frame.
.PP
Specify \fIfile\fP as \fI-\fP for standard input or output.
.PP
.SH ENVIRONMENT
.PP
.TP 4
.B DISPLAY
To get the default host, display number, and screen.
