I am trying to resize the uploaded image to height of 163px maintaining aspect ratio and then upload it to a folder. I tried with the following code:
$id=1; // user id
$this->load->library('image_lib');
$filename=$_FILES['file']['name'];
$config['image_library'] = 'gd2';
$config['upload_path'] = './userdata/'.$id;
$config['height'] = '163px';
$config['maintain_ratio'] = TRUE;
//$config['master_dim'] = 'height';
$config['source_image'] = $filename;
$this->load->library('upload', $config);
$this->image_lib->initialize($config);
$this->image_lib->resize();
if(!$this->upload->do_upload('file'))
{
echo $this->data['error'] = $this->upload->display_errors();
}
However this is uploading the image to the correct folder but the image is not resized. I uploaded an image of size *170*128* and it is uploaded to folder as it is without resizing. What is wrong with my code?
Can anyone help me to find the problem?
Thanks in advance.

Simple...
You have to do one thing Go to Captcha_helper.php and search
instead of
$x = mt_rand(0, $img_width / ($length / 3));
Do Like this
$x = mt_rand(0, $img_width / ($length / 1));

Try this cleaner version, the config for height or width doesn't need a px, hence your code is a little bit confusing :
$id = 1;
$config = array(
'upload_path' => './userdata/'.$id,
'allowed_types' => 'gif|jpg|jpeg|png',
'encrypt_name' => true,
);
$this->load->library('upload', $config);
$field_name = "file"; // change this with your file upload part's field name if different
if ($this->upload->do_upload($field_name)) {
$image = $this->upload->data();
$config = array(
'image_library' => 'gd2',
'source_image' => $image['full_path'],
'maintain_ratio' => true,
'height' => 163,
);
$this->load->library('image_lib', $config);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
}
$this->image_lib->clear();
}
