Update fabric.js Path points dynamically

Question

I\'m trying to add points to a path object dynamically. When I do, the path renders correctly, but the bounding rectangle never gets updated, making it nearly impossible for

Answer 1

In fabric 3.3.2 I solved it combining the answers above:

var dims = path._calcDimensions()
path.set({
  width: dims.width,
  height: dims.height,
  left: dims.left,
  top: dims.top,
  pathOffset: {
    x: dims.width / 2 + dims.left,
    y: dims.height / 2 + dims.top
  },
  dirty: true
})
path.setCoords()

This correctly updates my path bounding box after adding points like:

path.set({path: points})

I am not sure though, if this works with negative top and left values, but I didn't need that in my case. I guess the main thing is that the _parseDimensions() method was renamed to _calcDimensions().
