Codeigniter image cropping is not working

Question

I am using codeigniter 3.1 on localhost. I am trying to crop images but cropping is not working. Only resize working. So i enabled Gd2 php extension.

1.

public function do_crop($filename)
{
    $this->load->library('image_lib');
    $source_path =  'uploads/' . $filename;
    $target_path =  'uploads/thumb/'.$filename;

    $config = array(
        'image_library' => 'gd2',
        'source_image' => $source_path,
        'new_image' => $target_path,
        'maintain_ratio' => FALSE,
        'x_axis' => 300,
        'y_axis' => 100,
    );
    $this->image_lib->initialize($config);
} 

Image size = 1000X700

The output result is same as original image size 1000X700

2.

public function do_crop($filename)
    {
        $this->load->library('image_lib');
        $source_path =  'uploads/' . $filename;
        $target_path =  'uploads/thumb/'.$filename;

        $config = array(
            'image_library' => 'gd2',
            'source_image' => $source_path,
            'new_image' => $target_path,
            'maintain_ratio' => FALSE,
            'width' => 300,
            'height' => 300,
            'x_axis' => 350,
             'y_axis' => 50
        );
        $this->image_lib->initialize($config);
    } 

Image size = 1000X700

And the 2nd example only resize ( 300x300 ) the image but not cropped.

Answer 1

$config = array(
'source_image' => $upload_path.$image_data['file_name'],
'maintain_ratio' => FALSE,
'width' => 220,
'height' => 150,
'x_axis' => 350,
'y_axis' => 50
);
$this->image_lib->clear();
$this->image_lib->initialize($config);
$this->image_lib->crop();
