2 Permute the screen image like an 8-puzzle
6 $ slidescreen [-display host:display.screen] [-background color]
7 [-grid-size pixels] [-ibw pixels] [-increment pixels]
8 [-delay usecs] [-delay2 usecs] [-window] [-root]
11 The slidescreen program takes an image of the screen, divides it into
12 a grid, deletes a random square of that grid, and then randomly slides
13 one of the neighbors of this "hole" into the hole (and repeat.)
16 slidescreen accepts the following options:
19 Draw on a newly-created window. This is the default.
22 Draw on the root window.
25 The size of the grid cells. Default 70 pixels.
28 The size of the "gutter" between grid cells. Default 1 pixel.
31 How many pixels by which a piece should be moved when sliding to a new
32 location. Default 10 pixels.
35 How much of a delay should be introduced between steps of the animation of
36 the motion of each segment. Default 50000, which is 0.05 seconds. This
37 is closely related to the -increment parameter.
40 How much of a delay should be introduced between the end of the motion of
41 one segment and the beginning of the motion of another. Default 1000000,
47 to get the default host and display number.
50 to get the name of a resource file that overrides the global resources
51 stored in the RESOURCE_MANAGER property.
