usage

basic

node fishdraw.js > output.svg

specify seed (from a string), speed of drawing and output format:

node fishdraw.js --seed "Biggus fishus" --format smil --speed 2 > output.svg

• the seed string is used as the name of the fish (printed in the drawing). If unspecified, a random pseudo-Latin name will be auto generated.
• the speed number is used to control the speed of drawing animation. Larger the number is, faster it draws. This option works only with format smil.
• format options: svg (regular svg), smil (animated svg), csv (each polyline on a comma-separated line) and json.

use as JS library:

const {fish,generate_params} = require('./fishdraw.js');
let polylines = fish(generate_params());
console.log(polylines);
