NAME

spotlight - move spotlight around desktop  

SYNOPSIS

spotlight [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-radius pixels]  

DESCRIPTION

The spotlight program takes an image and exposes small sections of it as if through a wandering spotlight beam.

The image that it manipulates will be grabbed from the portion of the screen underlying the window, or from the system's video input, or from a random file on disk, as indicated by the grabDesktopImages, grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-demo(1) for more details.  

OPTIONS

spotlight accepts the following options:
-window
Draw on a newly-created window. This is the default.
-root
Draw on the root window.
-mono
If on a color display, pretend we're on a monochrome display.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
-delay microseconds
Slow it down.
-radius pixels
Radius of the spotlight in pixels.
