+First, an animation and a picture are generated. The Lottie file (lottie.json) is loaded into the picture, and then the picture is added to the canvas. The animation frames are controlled using the animation object to play the Lottie animation. Also you might want to know the animation duration time to run your animation loop.
 ```cpp
 animation->frame(animation->totalFrame() * progress);  //Set a current animation frame to display
 canvas->update(animation->picture());                  //Update the picture to be redrawn.
