NAME
xscreensaver-getimage - put some randomly-selected image on the root
window
SYNOPSIS
xscreensaver-getimage [-display host:display.screen] [--verbose] win‐
dow-id
DESCRIPTION
The xscreensaver-getimage program is a helper program for the xscreen‐
saver hacks that manipulate images. This is not a user-level command.
This program selects a random image, and puts it on the specified win‐
dow. This image might be a snapshot of the desktop; or a frame cap‐
tured from the system's video input; or a randomly-selected image from
disk.
OPTIONS
xscreensaver-getimage reads the ~/.xscreensaver file for configuration
information. It uses these settings:
grabDesktopImages
Whether it is acceptable to grab snapshots of the desktop. The
security paranoid might want to turn this off, to avoid letting
people see (but not touch!) your desktop while the screen is
locked.
grabVideoFrames
Whether it is acceptable to grab frames of video from the system's
video input. Grabbing of video is done by invoking the xscreen‐
saver-getimage-video(1) program.
chooseRandomImages
Whether it is acceptable to display random images found on disk.
Selection and loading of images is done by invoking the xscreen‐
saver-getimage-file(1) program.
imageDirectory
When loading images from disk, this is the directory to search.
The directory will be searched recursively, and all files in it are
assumed to be images.
If none of the three options are set to True, then video colorbars will
be displayed instead.
BUGS
If the target window is not the root window, then this program will
always grab a desktop image. This means that if an image-manipulating
xscreensaver mode is run in a normal window, it will always operate on
a desktop image; it's only when it is run in -root mode (or when
invoked by xscreensaver) that it will load image files or grab video.
