render watercolor images
Renders images that resemble watercolor paint splotches and outputs them as svg. Based on this post by Tyler Hobbs.
Installation
$ npm install dumasExample
So for example:
const fs = require('fs');
const dumas = require('dumas');
const shape = [
[593, 215, 1.1],
[407, 215, 1.5],
[257, 324, 0.9],
[200, 500, 0.5],
[257, 676, 0.7],
[407, 785, 0.9],
[593, 785, 0.2],
[743, 676, 1.1],
[800, 500, 1.9],
[743, 324, 0.3]
];
const svg = dumas(shape, {
fill: 'rgb(245, 10, 10)',
opacity: 0.02,
baseSigmas: [50, 30, 20, 20, 10, 10],
layerSigmas: [20, 10, 5, 5],
amountOfLayers: 150,
mutationFactor: 0.75,
mutationSigma: 0.1
});
fs.writeFileSync('output.svg', svg);API
dumas(shape, options) ⇒ string
Render watercolor images
Kind: global function Returns: string - The generated svg as a string
