Usage

Overview

The slidescreen program takes an image, divides it into a grid, deletes a random square of that grid, and then randomly slides one of the neighbors of this "hole" into the hole (and repeat.)

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

slidescreen 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.

--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.

--grid-size pixels

The size of the grid cells. Default 70 pixels.

--ibw pixels

The size of the "gutter" between grid cells. Default 4 pixel.

--increment pixels

How many pixels by which a piece should be moved when sliding to a new location. Default 10 pixels.

--delay microseconds

How much of a delay should be introduced between steps of the animation of the motion of each segment. Default 50000, which is 0.05 seconds. This is closely related to the --increment parameter.

--delay2 microseconds

How much of a delay should be introduced between the end of the motion of one segment and the beginning of the motion of another. Default 1000000, which is one second.

--duration seconds

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

--fps

Display the current frame rate and CPU load.

Environment

DISPLAY

to get the default host and display number.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

XSCREENSAVER_WINDOW

The window ID to use with --root.
