Installing

Download

You can Download pm-image-editor files from GitHub.

Use Bower to download the files.

bower install pm-image-editor

Use Npm to download the files.

npm install pm-image-editor

Add files

Add the scripts to your application. Make sure the pm-image-editor.js file is inserted after the angular.js library:

<script src="angular.js"></script>
<script src="pm-image-editor.js"></script>
<link rel="stylesheet" type="text/css" href="pm-image-editor.css">

Add a dependancy

Add the image crop module as a dependancy to your application module:

var myAppModule = angular.module('MyApp', ['pmImageEditor']);

Usage

Add the image editor directive <image-editor> to the HTML file where you want to use an image crop control. Note: a container, you place the directive to, should have some pre-defined size (absolute or relative to its parent). That's required, because the image crop control fits the size of its container.
Bind the directive to a source image property (using image="" option). The directive will read the image data from that property and watch for updates. The property should be a url to an image.
Bind the directive to a result image property (using result-image="" option). On each update, the directive will put the content of the crop area to that property in the data uri format.
Set up the options that make sense to your application.
Done!

Result image

The result image will be genarated based on transformations.

Example code

The following code enables to select an image using a file input and crop it. The cropped image data is inserted into img each time the crop area updates.

<html>
<head>
  <script src="angular.js"></script>
  <script src="pm-image-editor.js"></script>
  <link rel="stylesheet" type="text/css" href="pm-image-editor.css">
  <style>
    .cropArea {
      background: #E4E4E4;
      overflow: hidden;
      width:500px;
    }
  </style>
  <script>
    angular.module('app', ['pmImageEditor'])
      .controller('Ctrl', function($scope) {
        $scope.width = 500;
        $scope.image = 'test.jpg';
        $scope.selectionWidth = 100;
        $scope.selectionHeight = 70;
      });
  </script>
</head>
<body ng-app="app" ng-controller="Ctrl">
