20 The \fIslidescreen\fP program takes an image, divides it into
21 a grid, deletes a random square of that grid, and then randomly slides
22 one of the neighbors of this "hole" into the hole (and repeat.)
24 The image that it manipulates will be grabbed from the portion of
25 the screen underlying the window, or from the system's video input,
26 or from a random file on disk, as indicated by
27 the \fIgrabDesktopImages\fP, \fIgrabVideoFrames\fP,
28 and \fIchooseRandomImages\fP options in the \fI~/.xscreensaver\fP

34 accepts the following options:
37 Draw on a newly-created window. This is the default.
40 Draw on the root window.
43 Install a private colormap for the window.
45 .B \-visual \fIvisual\fP
46 Specify which visual to use. Legal values are the name of a visual class,
47 or the id number (decimal or hex) of a specific visual.
49 .B \-grid-size \fIpixels\fP
50 The size of the grid cells. Default 70 pixels.
53 The size of the "gutter" between grid cells. Default 4 pixel.
55 .B \-increment \fIpixels\fP
56 How many pixels by which a piece should be moved when sliding to a new
57 location. Default 10 pixels.
59 .B \-delay \fImicroseconds\fP
60 How much of a delay should be introduced between steps of the animation of
61 the motion of each segment. Default 50000, which is 0.05 seconds. This
62 is closely related to the \fI\-increment\fP parameter.
64 .B \-delay2 \fImicroseconds\fP
65 How much of a delay should be introduced between the end of the motion of
66 one segment and the beginning of the motion of another. Default 1000000,
69 .B \-duration \fIseconds\fP
70 How long to run before loading a new image. Default 120 seconds.
73 Display the current frame rate and CPU load.
78 to get the default host and display number.
81 to get the name of a resource file that overrides the global resources
