Package Exports

delaunify

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (delaunify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
