Overview
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-settings(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.
-
--window-id number -
Draw on the specified 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.
