Implementing an image format via JS is cool, but I&#x27;m not sure what the use-case is for this format that isn&#x27;t already covered (and supported in browsers) by other formats.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;APNG" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;APNG</a> should be a better alternative for GIF-like images (including transparency and low bit depth), and MP4 + H.265 should be the alternative for movie-like content.  For most platforms, you might even get decoding support in hardware, so performance and battery life shouldn&#x27;t be anything but better vs this.
