Overview
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 -

-
-mono -
If on a color display, pretend we're on a monochrome display.
-
