15 The goop program draws a simulation of bubbles in layers of overlapping
16 multicolored translucent fluid.
17
19 goop accepts the following options:
20
21 --window
22 Draw on a newly-created window. This is the default.
23
24 --root Draw on the root window.
25
26 --window-id number
27 Draw on the specified window.
28
29 --mono If on a color display, pretend we're on a monochrome display.
30
31 --install
32 Install a private colormap for the window.
33
34 --visual visual
35 Specify which visual to use. Legal values are the name of a
36 visual class, or the id number (decimal or hex) of a specific
37 visual.
38
39 --count integer
40 How many bubbles to draw per layer. Default: random.
41
42 --planes integer
43 How many planes to draw. Default: random, based on screen
44 depth.
45
46 --delay microseconds
47 How much of a delay should be introduced between steps of the
48 animation. Default 12000, or about 0.012 seconds.
49
50 --transparent
51 If --layers is greater than 1, then each layer will be drawn in
52 one color, and when they overlap, the colors will be mixed.
53 This is the default.
54
55 --non-transparent
56 Turns off --transparent.
57
58 --additive
59 If --transparent is specified, then this option means that the
60 colors will be mixed using an additive color model, as if the
61 blobs were projected light. This is the default.
62
63 --subtractive
64 If --transparent is specified, then this option means that the
65 colors will be mixed using a subtractive color model, as if the
66 blobs were translucent filters.
67
68 --xor Draw with xor instead of the other color tricks.
69
70 --fps Display the current frame rate and CPU load.
71
73 DISPLAY to get the default host and display number.
74
75 XENVIRONMENT
76 to get the name of a resource file that overrides the global
77 resources stored in the RESOURCE_MANAGER property.
78
79 XSCREENSAVER_WINDOW
80 The window ID to use with --root.
