Files & Dependencies

1. Include the js and css from /build/

<script src="freezeframe.min.js"></script> ``` 2. If you do not use a **packaged version** the following dependencies are required. These files can be found in **/src/js/vendor/**: * imagesLoaded Packaged v4.0.0 ( [https://github.com/desandro/imagesloaded](https://github.com/desandro/imagesloaded) ) * jQuery

Basic Usage: jQuery Plugin

1. Capture the image you want by selector and run the freezeframe() function.

$('.my_class').freezeframe(); ```

Basic Usage: Vanilla JS

1. Add freezeframe as a class name on the .gifs you want processed.

``` Add **freezeframe-responsive** as an additional class name to make the .gif responsive. ```

```

2. ✨ Freeze those frames ✨

$(function() { ff = new freezeframe().freeze(); }) ```

Advanced Usage

freezeframe.js exposes public methods to allow for more custom integration. You have the option of manually controlling when freezeframe captures images, adds support elements, and attaches event handlers. You can also manually trigger and release animation on one image or a group of images. These methods are described in detail in the Function Reference.

Capture .gifs and manually trigger / release animation:

logo = new freezeframe('#logo'); // setup freezeframe instance with custom selector

logo.capture(); // capture images by selector
logo.setup();   // setup support elements
logo.trigger(); // trigger animation
logo.release(); // release animation

Options Reference

Options can be passed to a freezeframe instance on creation in the form of an object or a string. Strings will be interpreted as the selector option.

// Options passed to jQuery plugin
$('.my_class').freezeframe({'animation_play_duration': 2500})

// String as selector option
var ff = new freezeframe('.my_class');

// Object as options
var ff = new freezeframe({
  'selector': '.my_class',
  'animation_play_duration': 3000,
  'non_touch_device_trigger_event': 'hover'
})

• selector string
  Default: ".freezeframe"
  The selector freezeframe will use to search for .gifs when the capture() function is run (if no custom selector is passed to the capture() function).

• animation_play_duration integer
  Default: 5000
  The number of milliseconds a .gif will animate for when triggered by click / touch event.

• non_touch_device_trigger_event string
  Default: "hover" Options: "hover", "click"
  The trigger event to start animation for non-touch devices.

Function Reference

• freezeframe( options )
  Creates a new freezeframe object instance. Can be passed options.

  // Default options
  var ff = new freezeframe();
  
  // String as selector option
  var ff = new freezeframe('.my_class');
  
  // Object as options
  var ff = new freezeframe({
  'selector': '.my_class',
  'animation_play_duration': 3000,
  'non_touch_device_trigger_event': 'hover'
  })

• capture( selector )
  Captures images to be paused by freezeframe. If run without selector argument, selector in freezeframe options will be used. Can be run multiple times with different selector to group many images, unrelated by selector, in one freezeframe instance.

  ff.capture();               // use selector in freezeframe options
  ff.trigger('.my_class');    // use custom selector

• setup()
  Creates and inserts support elements. Can be filtered by selector.

  ff.setup();                 // all images in freezeframe instance
  ff.setup('.my_class');      // filter images by selector

  HTML image before:

  <img class="freezeframe" src="my_image.gif" />
  

  ...and after:

  <div class="ff-container">
  <canvas class="ff-canvas ff-canvas-ready" width="400" height="250"></canvas>
  <img class="freezeframe ff-setup ff-image ff-image-ready" src="my_image.gif">
  </div>
  

• attach( selector )
  Attaches hover / click / touch events based on freezeframe options.

  ff.attach();                // all images in freezeframe instance
  ff.attach('.my_class');     // filter images by selector

• trigger( selector )
  Triggers (starts) animation. Can be filtered by selector.

  ff.trigger();               // all images in freezeframe instance
  ff.trigger('.my_class');    // filter images by selector

• release( selector )
  Releases (stops) animation.

  ff.release()                // all images in freezeframe instance
  ff.release('.my_class');    // filter images by selector
