spotlight [-display host:display.screen] [-foreground color] [-background color] [-window]
[-root] [-mono] [-install] [-visual visual] [-delay usecs] [-radius pixels]
The spotlight program takes an image and exposes small sections of it as if through a wan-
dering 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.
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 a private colormap for the window.
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.
Slow it down.
Radius of the spotlight in pixels.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in
the RESOURCE_MANAGER property.
