angular-crop

angular-crop is a Jcrop wrapper for angular framework. It offers a angular directive and a angular service that add image cropping functionality to your web application. The reason not to provide by angular module is that current angular module dependencies does not support load-on-demand, meaning that all module dependencies must be loaded before creating application module. load-on-demand feature is very significant in large scale SPA applications.

Good practice to build large scale SPA applications:

Usage

angular-crop is an object containing a directive method and a service method that you can feed it to angular.directive() and angular.service() directly.
directive: js function, you can feed it to angular.directive() as second parameter;
service: js function, you can feed it to angular.service() as second parameter;

traditional global namespace

include files:

<link rel="stylesheet" href="css/jquery.Jcrop.css">
<script type="text/javascript" src="js/jquery-1.11.0.js"></script>
<script type="text/javascript" src="js/jquery.Jcrop.min.js"></script>
<script type="text/javascript" src="js/angular-crop.js"></script>

controller:

var app = angular.module('app', []);
app.directive('angularCrop', angularCrop.directive);
app.controller('controllerName', function () {
	$scope.data = {
		x1: 0,
		y1: 0,
		x2: 200,
		y2: 200
	};
	$scope.events = {
		onChange: function () {
			console.log('changed', $scope.data);
		},
		onSelect: function () {
			console.log('selected', $scope.data);
		}
	};
});

view:

<img src="" angular-crop angular-crop-data="data" angular-crop-events="events" />

load angular-crop using requireJS

controller:

define(['app', 'angular-crop'], function (app, angularCrop) {
	app.register.directive('angularCrop', angularCrop.directive);
	app.register.controller('controllerName', function ($scope, $css) {
		$css.bind({href: 'app/views/css/jquery.Jcrop.css'}, $scope);
		$scope.data = {
			x1: 0, 
			y1: 0,
			x2: 200,
			y2: 200
		};
		$scope.events = {
			onChange: function () {
				console.log('changed', $scope.data);
			},
			onSelect: function () {
				console.log('selected', $scope.data);
			}
		};
	});
});

view:

<img src="" angular-crop angular-crop-data="data" angular-crop-events="events" />

or you can use service instead of directive.
controller:

define(['app', 'angular-crop'], function (app, angularCrop) {
	app.register.service('angularCrop', angularCrop.service);
	app.register.controller('controllerName', function ($scope, $css, angularCrop) {
		$css.bind({href: 'app/views/css/jquery.Jcrop.css'}, $scope);
		$scope.data = {
			x1: 0, 
			y1: 0,
			x2: 200,
			y2: 200
		};
		$scope.events = {
			onChange: function () {
				console.log('changed', $scope.data);
			},
			onSelect: function () {
				console.log('selected', $scope.data);
			}
		};
		angularCrop.angularCrop($('#imgID'), $scope.data, $scope.events);
	});
});

view:

<img src="" id="imgID" />
