Demo

To see the Cloudimage 360 view plugin in action, please check out the Demo page.

Step 1: Installation

Add script tag with CDN link to js-cloudimage-360-view lib after all content in body tag

<script src="https://cdn.scaleflex.it/plugins/js-cloudimage-360-view/2.4.1/js-cloudimage-360-view.min.js"></script>

You may also use major version number instead of fixed version to have the latest version available.

<script src="https://cdn.scaleflex.it/plugins/js-cloudimage-360-view/2/js-cloudimage-360-view.min.js"></script>

Step 2: Initialize

After adding the js-cloudimage-360-view lib, simply initialize it with class name "cloudimage-360", server folder path, file name and amount of images:

<div
   class="cloudimage-360"
   data-folder="https://scaleflex.cloudimg.io/crop/1920x700/n/https://scaleflex.airstore.io/demo/360-car/"

   data-amount="36"
></div>

Cloudimage Responsive Integration

See how it works (article on Medium)

Requirements

To use the Cloudimage Responsive plugin, you will need a Cloudimage token to deliver your images over CDN. Don't worry, it only takes seconds to get one by registering here. Once your token is created, you can configure it as described below. This token allows you to use 25GB of image cache and 25GB of worldwide CDN traffic per month for free.

data-responsive (or responsive)

Type: String (Cloudimage token) | Default: none | required for cloudimage responsive plugin

Enables cloudimage responsive plugin for 360 view.

data-filters (or filters)

Type: String | Default: q35 | optional

Applies default Cloudimage filters to your image, e.g. fcontrast, fpixelate, fgaussian, backtransparent, rotation... Multiple filters can be applied, separated by "." (dot).

Full documentation here.

Lazy Loading

Lazy loading is not included into js-cloudimage-360-view by default. There are well thought libraries to achieve that. If you enable lazy loading in the configuration, you need to add an additional library like lazysizes, yall.js (Yet Another Lazy Loader), lozad.js to handle it.

Implementation example with lazysizes

Implementation example with yall.js

Implementation example with lozad.js

to save API calls you man want to use one of our cdn bundles:

CDN link to js-cloudimage-360-view 1.1.0 + lazysizes 4.1.7

<script src="https://cdn.scaleflex.it/filerobot/js-cloudimage-360-view/v2.0.0.lazysizes.min.js"></script>

CDN link to js-cloudimage-360-view 1.1.0 + yall.js 3.1.1

<script src="https://cdn.scaleflex.it/filerobot/js-cloudimage-360-view/v2.0.0.yall.min.js"></script>

CDN link to js-cloudimage-360-view 1.1.0 + lozad.js 1.9.0

<script src="https://cdn.scaleflex.it/filerobot/js-cloudimage-360-view/v2.0.0.lozad.min.js"></script>
