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
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
