Adding dependency to your project

When you are done downloading all the dependencies and project files the only remaining part is to add dependencies on the mrImage AngularJS module:

angular.module('myModule', ['mrImage']);

Example

<div mr-image mr-src="image.src" mr-max-width="image.maxWidth"
     mr-selector="selector" mr-drawer="drawer"></div>

<img ng-src="{{cropResult}}">

var app = angular.module('DemoApp', ['mrImage']);

    app.controller('DemoCtrl', ['$scope', function ($scope) {

        $scope.image = {
            src: 'assets/times.jpg',
            maxWidth: 938
        };

        $scope.selector = {};

        $scope.drawer = [
            { x1: 625, y1: 154, x2: 777, y2: 906, color: '#337ab7', stroke: 1 },
            { x1: 778, y1: 154, x2: 924, y2: 906, color: '#3c763d', stroke: 1 },
            { x1: 172, y1: 566, x2: 624, y2: 801, color: '#a94442', stroke: 1 }
        ];

        $scope.addRect = function () {
            $scope.drawer.push({
                x1: $scope.selector.x1,
                y1: $scope.selector.y1,
                x2: $scope.selector.x2,
                y2: $scope.selector.y2,
                color: '#337ab7',
                stroke: 1
            });
            $scope.selector.clear();
        };

        $scope.cropRect = function () {
            $scope.cropResult = $scope.selector.crop();
        };
