Ken Burns Effect-style Slideshow Plugin for jQuery

jQuery.slideshowify.js is a jQuery plugin for creating a Ken Burns slideshow effect from images that match a selector. Images that don’t quite fit the window’s proportions (generally the case) are cropped and moved across the screen. This is also similar to the screensaver for Mac.

How to make use of it:

1. Load the necessary jQuery library and jQuery traversal plugin (for smooth CSS3 transitions and transitions) into the document.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/cdn/jquery.transit.min.js"></script>

2. Download and upload jquery.slideshowify.js after jQuery.

<script src="js/jquery.slideshowify.min.js"></script>

3. Create a container element to hold the slide show.

<div id="demo">
</div>

4. Define your image data in the JSON file as below.

// images.json
[
   {
      "src":"1.jpg",
      "w":"2000",
      "h":"1328"
   },
   {
      "src":"2.jpg",
      "w":"2000",
      "h":"1328"
   },
   {
      "src":"3.jpg",
      "w":"2000",
      "h":"1329"
   },
   // ...
]

5. Configure the plugin on the target element and specify the path to the JSON file.

$.slideshowify({
  parentEl : '#demo',
  dataUrl  : "js/photos.json",
  // dataType: "jsonp",
});

6. You can also configure the plugin on all images within the page to create a full-screen slideshow.

<img src="1.jpg" alt="Image 1" />
<img src="2.jpg" alt="Image 2" />
<img src="3.jpg" alt="Image 3" />
...

$("img").slideshowify();

7. The composition of the effect of burns.

$.slideshowify({
  parentEl : '#demo',
  dataUrl: "js/photos.json",
  fadeInSpeed: 1500,
  fadeOutSpeed: 1500,
  aniSpeedMin: 9000, 
  aniSpeedMax: 15000
});

8. Determine whether to randomize images.

$.slideshowify({
  parentEl : '#demo',
  dataUrl: "js/photos.json",
  randomize: true,
});

9. Functions.

$.slideshowify({
  parentEl : '#demo',
  dataUrl: "js/photos.json",
  filterFn: function(imgs){
    // filter data
    var fixedImgs = [];
    $.each(imgs, function(i, img){
      fixedImgs.push($.extend(img.versions["9"], {id:img.id}));
    });
    return fixedImgs;
  },
  afterFadeIn : function(curImage){
    // do something
  },
  beforeFadeOut : function(curImage){
    // do something else
  }
});
