Resize function

public function resize($source, $destination, $width, $height) {
    $config['image_library'] = 'gd2';
    $config['source_image'] = $source;
    $config['create_thumb'] = TRUE;
    $config['maintain_ratio'] = TRUE;
    $config['width'] = $width;
    $config['height'] = $height;
    $config['new_image'] = $destination;
    $this->load->library('image_lib', $config);
    $this->image_lib->resize();
}

Answer 1

First of all you are loading library two times in your function add please load it one time probably at the top of function.

in resize use $this->image_lib->initialize($config) as below

public function resize($source, $destination, $width, $height) {
    $config['image_library'] = 'gd2';
    $config['source_image'] = $source;
    $config['create_thumb'] = TRUE;
    $config['maintain_ratio'] = TRUE;
    $config['width'] = $width;
    $config['height'] = $height;
    $config['new_image'] = $destination;
    $this->load->library('image_lib');
    $this->image_lib->initialize($config);
    $this->image_lib->resize();
}
