Create a folder “uploaded” where your “application” folder is. (Not inside “application” folder”). Create a sub folder “thumbs” inside “uploaded”. Put a font in system/fonts/arial.ttf (copy the font from your windows).

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Imagetest extends CI_Controller {
	function __construct() {
		parent::__construct();
		$this->load->helper('url');
	}
	function index() {
		$path = realpath(APPPATH . '../uploaded');
		$file = "asd.jpg";

$path = str_replace('\\','/',$path);
		$config = array(
			'source_image' => $path.'/'.$file,
			'new_image' => $path.'/thumbs/'.$file,
			'maintain_ration' => true,
			'width' => 150,
			'height' => 100,
			'x_axis' => '100',
			'y_axis' => '40',
			'rotation_angle' => '180',
			'wm_text'		=> 'Test asdfsda sa dsa dsa dsa a',

		);
		print "<pre>";
		print_r($config);
		$this->load->library('image_lib', $config);

		//$this->image_lib->crop();
		//$this->image_lib->clear();

		$this->image_lib->clear();
		if(!$this->image_lib->watermark()) {
