1 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] 2 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.) 2 OPTIONS slidescreen accepts the following options: -window Draw on a newly-created window. This is the default. -root Draw on the root window. -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 isone second. 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. 2 COPYRIGHT Copyright (co 1992 by Jamie Zawinski.
