How to resize the image by dragging

Hope this angular directive helps

(function () {
  'use strict';

  angular.module('myApp', [])

  .directive('resizable', function () {

    return {
        restrict: 'A',
        scope: {
            callback: '&onResize'
        },
        link: function postLink(scope, elem, attrs) {
            elem.resizable({handles: "all"});
            elem.on('resize', function (evt, ui) {
              scope.$apply(function() {
                if (scope.callback) { 
                  scope.callback({$evt: evt, $ui: ui }); 
                }                
              })
            });
        }
    };
  })


  .controller('MainCtrl', function ($scope) {

    $scope.resize = function(evt,ui) {
      //console.log (evt,ui);
      $scope.w = ui.size.width;
      $scope.h = ui.size.height;
    }

  });

})();
