cwaves (6x)

cwaves [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-waves int] [-colors int] [-fps]

The cwaves program draws a languidly-scrolling vertical field of sinusoidal colors.

cwaves accepts the following options:

-window

Draw on a newly-created window. This is the default.

-root

Draw on the root window.

-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.

-fps

Display the current frame rate and CPU load.

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.
