pixelizer

Small script to create a pixel animation based on an image. Script will draw image on canvas, create pixels out of image and then animate those pixels to render the image at the end.

This script is based on the work of Louis Hoebregts @Mamboleoo on codepen: https://codepen.io/Mamboleoo/pen/obWGYr. I took his algorithm, put it into a class and customized it with different options.

demo

try out on https://mevimedia.de/pixelizer

implementation

import Pixelizer

 import 'Pixelizer' from './pixelizer.js'

usage

create new Instance with data-object:

 let pixelizer = new Pixelizer({data})

data

data = {

      canvas: '#canvas', -> mandatory: DOM-Selector for canvas element

      src: './image.svg', -> mandatory: Source for image file. can be svg, png, jpeg.

      options: { -> optional parameters:

          pixelRadius = 5, // size of pixels

          amount = 150, // amount of pixel

          threshhold = 150, //range: 1-254, threshhold for pixel values from original img

          colors = ["#FFFFFF"], // array with colors for random colorization of pixels

          verticalDistribution = 5, // how far pixels fly around vertically

          horizontalDistribution = 5, // how far pixels fly around horizontally

          friction = false, // if friction is true, pixels will not head straight to destination. if true, speed is ignored

          frictionValue = 1, // range: 1-10, define variation of 

          autoinit = true // wether animation starts on instance creation. if set to false, init animation with pixelizer.init()

          speed = 100 // 1-1000: how fast pixels will get to destination
      }
 }
