fabricjs - Is there a method for recalculating/updating the bounding rect of an object in fabric.js? -

i trying make modifiable cubic bezier curve in fabric.js. problem have when update curve dragging control points, bounding rectangle of curve not update.

i have (ugly) code here: http://codepen.io/andershj/pen/pbwqzx?editors=1000

as can see example, bounding rect not update after updating curve.

is there method updating/recalculating bounding rect?

... canvas.on({    'object:modified' : onobjectmodified });  function onobjectmodified(e) {     canvas.setactiveobject(e.target.line.curve);     // there method recalculate bounding rect when object modified? } ... 

it's bit tricky can solve this:

function onobjectmodified(e) {   e.target.line.curve.pathoffset = null;   e.target.line.curve._setpositiondimensions({});   canvas.setactiveobject(e.target.line.curve); }
