How to resize a image while uploading in ZF2 - file-upload

Question

I'm new to Zend Frame work and I need to implement image resize while uploading in zend framework 2. I try to use the method in image resize zf2 but it didnot work for me.
please help?
public function addAction(){
$form = new ProfileForm();
$request = $this->getRequest();
if ($request->isPost()) {
$profile = new Profile();
$form->setInputFilter($profile->getInputFilter());
$nonFile = $request->getPost()->toArray();
$File = $this->params()->fromFiles('fileupload');
$width = $this->params('width', 30); // #todo: apply validation!
$height = $this->params('height', 30); // #todo: apply validation!
$imagine = $this->getServiceLocator()->get('my_image_service');
$image = $imagine->open($File['tmp_name']);
$transformation = new \Imagine\Filter\Transformation();
$transformation->thumbnail(new \Imagine\Image\Box($width, $height));
$transformation->apply($image);
$response = $this->getResponse();
$response->setContent($image->get('png'));
$response
->getHeaders()
->addHeaderLine('Content-Transfer-Encoding', 'binary')
->addHeaderLine('Content-Type', 'image/png')
->addHeaderLine('Content-Length', mb_strlen($imageContent));
return $response;
$data = array_merge(
$nonFile,
array('fileupload'=> $File['name'])
);
$form->setData($data);
if ($form->isValid()) {
$size = new Size(array('min'=>100000)); //minimum bytes filesize
$adapter = new \Zend\File\Transfer\Adapter\Http();
$adapter->setValidators(array($size), $File['name']);
if (!$adapter->isValid()){
$dataError = $adapter->getMessages();
$error = array();
foreach($dataError as $key=>$row)
{
$error[] = $row;
}
$form->setMessages(array('fileupload'=>$error ));
} else {
$adapter->setDestination('./data/tmpuploads/');
if ($adapter->receive($File['name'])) { //identify the uploaded errors
$profile->exchangeArray($form->getData());
echo 'Profile Name '.$profile->profilename.' upload '.$profile->fileupload;
}
}
}
}
return array('form' => $form);
}

I get answer for this question by adding external library to zend module.It is a easy way for me. i used http://www.white-hat-web-design.co.uk/blog/resizing-images-with-php/ class as external library.this is my controller class.
class ProfileController extends AbstractActionController{
public function addAction()
{
$form = new ProfileForm();
$request = $this->getRequest();
if ($request->isPost()) {
$profile = new Profile();
$form->setInputFilter($profile->getInputFilter());
$nonFile = $request->getPost()->toArray();
$File = $this->params()->fromFiles('fileupload');
$data = array_merge(
$nonFile,
array('fileupload'=> $File['name'])
);
//set data post and file ...
$form->setData($data);
if ($form->isValid()) {
$size = new Size(array('min'=>100000)); //minimum bytes filesize
$adapter = new \Zend\File\Transfer\Adapter\Http();
$adapter->setValidators(array($size), $File['name']);
if (!$adapter->isValid()){
$dataError = $adapter->getMessages();
$error = array();
foreach($dataError as $key=>$row)
{
$error[] = $row;
}
$form->setMessages(array('fileupload'=>$error ));
} else {
$adapter->setDestination('//destination for upload the file');
if ($adapter->receive($File['name'])) {
$profile->exchangeArray($form->getData());
//print_r($profile);
echo 'Profile Name '.$profile->profilename.' upload '.$profile->fileupload;
$image = new SimpleImage();
$image->load('//destination of the uploaded file');
$image->resizeToHeight(500);
$image->save('//destination for where the resized file to be uploaded');
}
}
}
}
return array('form' => $form);
}
}
