Can JavaScript Control GIF Animation?

Controlling GIF Animation with JavaScript

Gif animation is commonly used on the web to add visual interest and depth to web pages. However, you may sometimes want to pause, play, or even choose the specific frame of a GIF to display. Is there a way to do this using JavaScript?

Yes, you can use the libgif library to control GIF animation with JavaScript.

This library provides an easy-to-use API that allows you to manipulate GIF images. To use it, simply include the following script tag in your HTML:

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

Then, you can utilize the libgif functionality to interact with GIF images. For instance, the following code loads a GIF and allows you to rub on it to advance the frame:

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

<script type="text/javascript">
    $$('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');
            });
        }
    });
</script>
Copy after login

This code illustrates how to interact with GIF images using libgif's API. By leveraging this library, you can control various aspects of GIF animation, including playback, frame selection, and user interaction.
