Overview
The cwaves program draws a languidly-scrolling vertical field of sinusoidal colors.
Options
cwaves accepts the following options:
-
--window -
Draw on a newly-created window. This is the default.
-
--root -
Draw on the root window.
-
--window-id number -

-
--mono -
If on a color display, pretend we're on a monochrome display.
-
--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.
-
--delay microseconds -
How much of a delay should be introduced between steps of the animation. Default 20000, or about 1/50th second.
-
--waves int -
How many cosines to add together. The more waves, the more complex the apparent motion.
-
--colors int -
How many colors to use. Default 800. The more colors, the smoother the blending will be.
