NOTE: this is a fork of alexk111/ngImgCrop, inspired by a pen by Hugh Anderson Angular(1) directive for cropping identity photographs. The forked directive add these attributes to the <img-crop> element:

• tollerance-ratio : set a tolerance on the image ratio (width / height) (in percent, es. 10)
• can-rotate: enable image rotation
• min-resolution: prevent image cropping if the image does not satisfied the minimum requested resolution (DPI)

• npm
• bower

npm install
bower install
gulp build-unminified

will produce ng-img-crop.css and ng-img-crop.js in the compile/unminified folder. This file loads the directive, include it where needed

<script src="ng-img-crop.js"></script>
<link rel="stylesheet" type="text/css" href="ng-img-crop.css">

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

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

Follow these instructions and then consider that:

• you can add rotation by setting the can-rotate attributo of the <img-crop> element to true
• you can set the miminum resolution by setting the min-resolution attribute
• you can set the resolution tollerance by setting the tollerance-ratio attribute
