<div id="demoCanvas" style="styles..."></div>

1. Load Animation

var player = new SVGA.Player('#demoCanvas');
var parser = new SVGA.Parser();
parser.load('rose_2.0.0.svga', function(videoItem) {
    player.setVideoItem(videoItem);
    player.startAnimation();
})

Load Animation Automatically

Assign canvas element properties as below.

<div src="rose_2.0.0.svga" loops="0" clearsAfterStop="true" style="styles..."></div>

Animation will play after Web-Page onload.

Replace Animation Images Dynamically
