This question has been asked here. But instead of a rectangular boundary, I want it to be a circle
I tried working around on one of the answers from the previous question. Here's its fiddle link. But haven't accomplished anything.
var boundingBox = new fabric.Circle({
fill: "transparent",
radius: 200,
hasBorders: false,
hasControls: false,
lockMovementX: true,
lockMovementY: true,
evented: false,
stroke: "red"
});
