Codeigniter Image Manipulation Class Library
Codeigniter Image Manipulation Class Library – We can load image manuipulation class library like this $this->load->library(‘image_lib’);. This library provide various functions that are used for image resizing, thumbnail creation, image cropping, image rotating and image watermarking. It has three major image libraries supported – GD/GD2, NetPBM and ImageMagick. Here in this tutorial, we are going to explain how to use image manipulation class library.
Codeigniter image manipulation class library
Let us understand how image manipulation class library works in codeigniter with examples.
Load image manipulation class library
First load image manipulation class library to use its functions, this library can be loaded simply as below-
How to load image manipulation class library:
$this->load->library('image_lib');

Functions:-
There are following functions available in image manipulation class library. Now let us understand one by one with example.
- 1. Processing an image.
- 3. Image watermarking.
1. Processing an image
This method performs resizing, cropping, rotation, or watermarking of image :-
EXAMPLE
Here is simple example of Processing an image function.
Controller code:-
Your controller code now look like this:-
load->library('image_lib', $config);
echo $this->image_lib->resize();
echo $this->image_lib->display_errors();
}
}?>

2. Image watermarking
Two types of watermarking :-
There are two types of watermarking that we can use.
- 1. Text.
- 2. Overlay.
EXAMPLE
Controller code:-
Your controller code now look like this:-
load->library('image_lib');
$config['image_library'] = 'gd2';

'rules' => 'required',
'errors' => array('required' => 'You must provide a %s.',
),),
array(
'field' => 'passconf',
'label' => 'Password Confirmation',
'rules' => 'required'),
array(
'field' => 'email',

Codeigniter Config Class Library
Codeigniter Config Class Library– Configuration is an important part of any framework, codeigniter provides default configuration file where we can add the application configuration settings. $this->config->load(‘filename’); loads the configuration file. Sometimes we need to create custom configuration file, codeigniter provides an easy way to create custom config files. It is very simple to create custom configuration file in codeigniter. Here in this tutorial we are going to explain with various examples.

Where file_name is name of the configuration file that you want to load.
Working with config file :-
Let us understand how to use default configuration file and create own custom configuration file.
How to Create Custom Configuration File?
To create custom config file first go to config folder and create a file named config_custom.php in config folder.
You can load config files in following ways-
- 1. Auto loading : Codeigniter has auto-load function which helps us to load library, helpers and models.
- 2. Manual loading : We can load config files manually.

6. Base Url
base_url()
Base Url function returns url of your site along with optional path like stylesheet or image.
7. System Url
system_url()
