smartcrop-rails gem is the integration of smartcrop.js javascript library for your Rails 4 application.
Smartcrop.js implements an algorithm to find good crops for images. Demo: For content aware image cropping http://29a.ch/2014/04/03/smartcrop-content-aware-image-cropping
source: https://github.com/jwagner/smartcrop.js/
Add this line to your application's Gemfile:
gem 'smartcrop-rails'
And then execute:
$ bundle
Or install it yourself as:
$ gem install smartcrop-rails
Now you need to edit your app/assets/javascripts/application.js
file and add the following line:
//= require smartcrop
Here is the example working code to test with your Rails application.
Add this sample code to your app/assets/javascripts/application.js
file
$(document).ready(function(){
SmartCrop.crop(image, {width: 100, height: 100}, function(result){console.log(result);});
});
Note: Here i am using gem 'jquery-turbolinks'
for using the jquery $(document).ready function
