    Interface EventBus

    // Listen frame index changes:
    viewer.eventBus.on("frame-index-changed", function(args) { console.log("Image frame changed", args); });

    // Listen "after-open" event once:
    viewer.eventBus.on("after-open", function(args) { console.log("Image opened", args); }, { once: true });
