Overview
The hopalong 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.
-
-count integer -
How many pixels should be drawn before a color change. Default 1000.
-
-ncolors integer -
How many colors should be used (if possible). Default 100. The colors used cycle through the hue, making N stops around the color wheel.
-
-timeout seconds -
How many seconds we should generate for before clearing the screen and starting over. Default 20.
-
-delay microseconds -
How long we should wait between drawing each pixel. Default 0.
