.TH XScreenSaver 1 "07-Sep-2003 (4.13)" "X Version 11"
.SH NAME
xscreensaver-getimage-desktop - put a desktop image on the root window
.SH SYNOPSIS
.B xscreensaver-getimage-desktop
[\-display \fIhost:display.screen\fP] [\--verbose] [\--stdout]
.SH DESCRIPTION
The \fIxscreensaver\-getimage\-desktop\fP program is a helper program
for the xscreensaver hacks that manipulate images.  Specifically, it
is invoked by
.BR xscreensaver\-getimage (1)
as needed.  This is not a user-level command.

This program is only used on MacOS X / XDarwin systems, because
on those systems, it's necessary to use the
.BR screencapture (1)
program to get an image of the desktop -- the usual X11
mechanism for grabbing the screen doesn't work on OSX.

This script works by running
.BR screencapture (1)
to get a PDF, then converting it to a JPEG with
.BR pdf2jpeg (1),
then loading it onto the window with
.BR xscreensaver\-getimage\-file (1).
.SH OPTIONS
.I xscreensaver-getimage-desktop
accepts the following options:
.TP 4
.B --verbose
Print diagnostics.
.TP 4
.B --stdout
Instead of loading the image onto the root window, write it to stdout
as a PBM file.
