To draw an animated gif with KineticJS, you can follow these steps:

var stage = new Kinetic.Stage({
  container: 'container',
  width: 500,
  height: 500
});

var layer = new Kinetic.Layer();


  1. Load the animated gif image into an image object:

var imageObj = new Image();
imageObj.onload = function() {
  var gif = new Kinetic.Image({
    image: imageObj,
    x: 0,
    y: 0,
    width: imageObj.width,
    height: imageObj.height
  });

  layer.add(gif);
  stage.add(layer);

  // Add animation to the image
  var anim = new Kinetic.Animation(function(frame) {
    // Update the image position or properties here
  }, layer);

  anim.start();
};

imageObj.src = 'path/to/animated.gif';


  1. Update the position or properties of the image within the animation function to create the animation effect.
  2. Start the animation with anim.start().
  3. Finally, don't forget to add the layer to the stage and the image to the layer.


By following these steps, you can create an animated gif using KineticJS.
