Add cropping option to an image form

I’ve the next form.

$form['imagen'] = array(         '#title' => t('Image'),         '#type' => 'managed_file',         '#upload_validators' => array('file_validate_extensions' => array('jpeg jpg png gif')),         '#upload_location' => 'public://',         '#progress_indicator' => 'throbber',         '#status' => FILE_STATUS_PERMANENT,         '#progress_message' => 'One moment while we save your file...',     );

That generates something like this:

enter image description here

What I need is to give the user the option to see the image that he has upload, and resize the image. The functionality that I need, is the same that the ImageField_crop module gives.

I’m totally lost. I don’t know how to add this functionality to the form. It’s totally necessary for the project to insert this form in a custom module, because I have a multistep form.

Does anybody know how to do this??

Thank you very much.
