       spotlight - move spotlight around desktop


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


       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.


       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.

       -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.

       -duration seconds
               How long to run before loading a new image.  Default 120 seconds.

       -radius pixels
               Radius of the spotlight in pixels.

       -fps    Display the current frame rate and CPU load.


       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.
