javascript - Set position for object while adding it to canvas in Fabric.js

Question

I am adding an object to my fabric.js canvas using JavaScript (in a React.JS project), but I don't want it to be rendered in the top left corner every time. I want it so that when I use the canvas.add() function, I can specify the x, y co-ordinates at which I can render the object.

Something like this maybe -

const addObject = (canvas) => {
  img = fabric.Image(img);
  canvas.add(img, 20, 15) //(20,15) represent the x,y co-ordinates of where I want to render img

I just want it so that my object is added to the specified position automatically on calling the addObject() function.

You can try using the LEFT and TOP. For example, locating can be done this way. This could be an example for you.

var circle = new fabric.Circle({
left: 20,
top: 15,
radius: 25,
fill: randomColor(),
hasRotatingPoint: true
});
canvas.add(circle)

If you want it to be random, you can use it as follows.

 var circle = new fabric.Circle({
 left: fabric.util.getRandomInt(25, canvas.width - 25),
 top: fabric.util.getRandomInt(25, canvas.height - 25),
 radius: 25,
 fill: randomColor(),
 hasRotatingPoint: true
 });
 canvas.add(circle);

Hopefully it benefits your business.
