delaunify v1.0.3

delaunify

Randomly delaunay-triangulates an image by distributing 2D points across the surface, and then triangulating it. The colours of each triangle is determined by the pixel color underneath the triangle's centroid.

A new canvas is returned with the same size as the image.

var load = require('img')
var domready = require('domready')
var uri = require('baboon-image-uri')
var delaunify = require('delaunify')

domready(function() {
	//load image with baboon for testing
	load(uri, function(err, img) {
		if (err) 
			throw err

		//delaunify the image into a canvas
		var result = delaunify(img, { count: 350 })
		document.body.appendChild(result)
	})
})

Usage

delaunify(img[, opts])

Triangulates the image. By default, it uses a random distribution of points.

Options:

• min an x,y array for the minimum random value (default [0, 0])
• max an x,y array for the maximum random value (default [imgWidth, imgHeight])
• count the number of points to distribute (default 50)
• fill a boolean, whether to apply a fill (default true)
• stroke a boolean, whether to apply a stroke (default true)
• points an array of x,y points to use instead of random; this will ignore the min, max and count options
