A react component to render video-like playback for image sequences 🎥.

View Demo

Installation

Via NPM:

npm install canvas-image-scrubber

or Yarn:

yarn add canvas-image-scrubber

Basic Usage with webpack and file-loader

frames is a required prop which must be an array of valid image paths to each frame of your image sequence.

render is also a required prop. It is a render-prop which allows you to render the image sequence player, controls, playback progress bar, and audio controls however you wish. See below for basic usage, and ./demo/src/index.js for more advanced usage with prop getters getViewerControlsProps and getViewerProgressProps.

More robust documentation will hopefully be coming soon.. 🤠

import React from 'react';
import CanvasImageScrubber from 'canvas-image-scrubber';
export function getFrames() {
  let i = 1;
  const frames = [];
  while (i < 39) {
    frames.push(require(`./frames/Frame-${i}.jpg`));
    i++;
  }
  return frames;
}

const frames = getFrames();

function MyApp() {
  render() {
    <CanvasImageScrubber
      frames={frames}
      render={({ renderViewer }) => {
        return (
          <div>
            {renderViewer}
          </div>
        )
      }}
    />
  }
}

Optionally render your own canvas element

The render props provided in the render prop callback provide a getCanvasRef which will allow you to render your own canvas element should you need to do so. Use getCanvasRef as the value for the prop ref on your canvas element, this way canvas-image-scrubber can get a dom reference to your canvas element. Usage example:

function MyApp() {
  render() {
    <CanvasImageScrubber
      frames={frames}
      render={({ getCanvasRef }) => {
        return (
          <div>
            <canvas ref={getCanvasRef} />
          </div>
        )
      }}
    />
  }
}
