By default fabric.js elements come with 8 points to scale any objects. But the app I\'m working specifically requires that stretching should not be allowed on a single axis (hor
imgInstance.setControlsVisibility({ mt: false, mb: false, ml: false, mr: false, bl: false, br: false, tl: false, tr: false, mtr: false, });
change "imgInstance" to be your object.
