Can JavaScript Control GIF Animations?

Controlling GIF Animations with JavaScript: Is It Possible?

Manipulating GIFs through JavaScript allows for greater control over animations and improves web efficiency by reducing file count. Here's how you can achieve this:

Solution:

The libgif library offers the functionality needed to control GIF animations.

Implementation:

1. Include the libgif.js script:

   <script type="text/javascript" src="./libgif.js"></script>

2. Load the GIF image with appropriate attributes:

   <img src="./example1_preview.gif" rel:animated_src="./example1.gif"
    width="360" height="360" rel:auto_play="1" rel:rubbable="1" />

3. Instantiate and load SuperGif:

   $$('img').each(function (img_tag) {
    if (/.*\.gif/.test(img_tag.src)) {
        var rub = new SuperGif({ gif: img_tag } );
        rub.load(function(){
            console.log('oh hey, now the gif is loaded');
        });
    }
   });

This code uses libgif to control the GIF, including starting/stopping the animation and displaying specific frames. The example provided demonstrates the loading of the GIF and the console logging of its completion.
