NAMEspotlight - move spotlight around desktop
SYNOPSISspotlight [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-radius pixels]
DESCRIPTIONThe 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.
OPTIONSspotlight accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- 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.
- -radius pixels
- Radius of the spotlight in pixels.
- 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.
