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

Please, fabricjs does not support adding point dinamically as of now. To make it work you can add points like you are doing and then use internal method path._parseDimensions() each time you add points and desire to update bounding box dimension.

var dims = path._parseDimensions();
path.setWidth(dims.width);
path.setHeight(dims.height);
path.pathOffset.x = path.width/2;
path.pathOffset.y = path.height/2;
path.setCoords();

Look this updated fiddle that has the necessary code to solve your problem. I hope it works for every situation.
