How can I change the image of the fabric.Image object attribute src, if I have already made an animation?
You can use .setElement() to change the image.
For example, let's say you have a fabricJS image object called myFabricObect.
Then, if you have an html image element on your page, you can load your myFabricObject with the "newImage" like this:
myFabricObject.setElement(document.getElementById("newImage"));
You could also create a javascript Image() and assign that to myFabricObject:
var img=new Image();
img.onload=function(){
myFabricObject.setElement(img);
}
img.src="myNewImage.png";
