Description:

A scroll-triggered image sequence animation (also called frame animation) inspired by Apple Airpods website.

Implemented in JavaScript and Canvas.

How to use it:

1. Install and import the Canvas Scroll Clip.

# Yarn
$ yarn add canvas-scroll-clip
# NPM
$ npm i canvas-scroll-clip --save

import CanvasScrollClip from "canvas-scroll-clip";

2. Initialize the CanvasScrollClip on the target container element, specify the path to the first image, determine the total number of animation frames, and set the height of the scroll area as follows:

new CanvasScrollClip(document.querySelector('.example'), {
    framePath: "https://www.apple.com/105/media/us/airpods-pro/2019/1299e2f5_9206_4470_b28e_08307a42f19b/anim/sequence/large/01-hero-lightpass/0001.jpg",
    frameCount: 140,
    scrollArea: 2000,
    identifier: '',
})

CanvasScrollClip.events.on('viewport.scroll', function(scrollTop){
  console.log(scrollTop);
});
CanvasScrollClip.events.on('viewport.resize', function(){
  // on resize
});
CanvasScrollClip.events.on('images.loaded', function() {
  // on image loaded
});
CanvasScrollClip.events.on('images.progress', function() {
  // after every image preloaded
});
