Answer 1

$file_name="uploaded_image";
$path="folder path to ur file";
 $config = array();
$config['source_image'] = $path . $file_name;
        $config['new_image'] = $path."/crop/" . $data['file_name'];

        $config['width'] = 350;

        $config['height'] = 250;
        $config['create_thumb'] = FALSE;
        $config['maintain_ratio'] = TRUE;
        $this->load->library('image_lib', $config);
        $this->image_lib->initialize($config);
        $this->image_lib->resize();
