Description

The hop program generates real plane fractals as described in the September 1986 issue of Scientific American.

Options

hopalong 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.

-ncolors integer

How many colors should be used (if possible).  Default 200. The colors used cycle through the hue, making N stops around the color wheel.

-cycles integer

How long to run each batch.  Default 2500 pixels.

-count integer

How many pixels should be drawn before a color change.  Default 1000.

-jong integer
-no-jong integer

Whether to use the Jong format (default is to choose randomly.)

-sine integer
-no-sine integer

Whether to use the Sine format (default is to choose randomly.)

-fps

Display the current frame rate and CPU load.

Environment

DISPLAY

to get the default host and display number.

XENVIRONMENT
