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
options in the ~/.xscreensaver
(1) for more details.
accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- 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
- Display the current frame rate and CPU load.
- to get the default host and display number.
