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-demo(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.
-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.
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.
