xscreensaver-getimage(1) XScreenSaver manual xscreensaver-getimage(1)
NAME
xscreensaver-getimage - put some randomly-selected image on the root
window
SYNOPSIS
xscreensaver-getimage [-display host:display.screen] [--verbose] win-
dow-id [pixmap-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 or pixmap. This image might be a snapshot of the desktop; or a
frame captured from the system's video input; or a randomly-selected
image from disk.
If only a window ID is specified, the image will be painted there. If
both a window ID and a pixmap ID are specified, then the image will be
painted on the pixmap; and the window may be modified as a side-effect.
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
When grabbing desktop images, the window argument will be unmapped and
have its contents modified, causing flicker. (This does not happen
when loading image files or video frames.)
