NAME
slidescreen - permute the screen image like an 8-puzzle
SYNOPSIS
slidescreen [-display host:display.screen] [-background color] [-grid-
size pixels] [-ibw pixels] [-increment pixels] [-delay usecs] [-delay2
usecs] [-window] [-root] [-install] [-visual visual]
DESCRIPTION
The slidescreen program takes an image of the screen, 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.)
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 1 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.
-delay 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.
RESOURCES
On some systems (currently, only SGIs), this program can, instead of
grabbing a desktop image, grab a frame of video from an external camera
and manipulate that instead. The following resources control that.
grabVideoProbability (Float)
What portion of the time to grab video rather than a screen
image, between 0.0 and 1.0. Defaults to 0.5, or half the time.
videoDevice (Integer)
The number of the default video input device to check first.
If unspecified, the default camera (from videopanel(1)) will be
checked first. After that, all other available video input
devices will be checked in order.
The first one which produces a non-black image will be used.
If all images are black, the others will be re-checked a few
times before giving up and falling back to simply grabbing a
desktop image (but note that this takes a few seconds, so if
you don't actually have any video sources hooked up, you should
consider turning off video grabbing by setting grabVideoProba‐
bility to 0.0.)
videoGain (Float)
The amount by which to brighten the grabbed image. This
defaults to 2.2.
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.
