bumps man page

bumps — move distorting spotlight around desktop

Synopsis

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

Description

The bumps program takes an image and exposes small, distorted sections of it as if through an odd 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

bumps 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.

-duration seconds

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

-fps

Display the current frame rate and CPU load.
