Compress Image

Codeigniter Library to Compress Image

This library was developed with the purpose of optimizing the images in size and quality.

How to use

First you need to download the Compress.php file and put inside Codigniter library folder of your project (project/application/libraries)

Inside of your controller or other class that you want to use, add this code:

$this->load->library('Compress');  // load the codeginiter library

$file = 'path/to/file/filename.extension'; // file that you wanna compress
$new_name_image = 'new_name_of_file'; // name of new file compressed
$quality = 60; // Value that I chose
$pngQuality = 9; // Exclusive for PNG files
$destination = 'final_path/to/file/'; // This destination must be exist on your project

Initiate the class:

$compress = new Compress();

Add values to each element:

$compress->file_url = $file;
$compress->new_name_image = $new_name_image;
$compress->quality = $quality;
$compress->pngQuality = $pngQuality; // Exclusive for PNG files, don´t need to set
$compress->destination = $destination;

And finally let the library do the rest for you:

$result = $compress->compress_image();

Result

The library will always return for you a array with this specific data:

Item	Description	Examples
image	New name of compressed image	eg.: new_file_name.extension
real_file_path	Real file path of a compressed image	eg.: X:/path/to/folder/of/project/new_file_name.extension
url_file_path	Site url file of a compressed image	eg.: http://url/to/project/folder/new_file_name.extension

Don't use CI to create your projects?

You can use this composer library that I've created, it's almost the same thing.
