README

What is phpgif?

phpgif is a PHP library to generate GIFs - easily!

Installing phpgif

Using Composer

Run the following command in Terminal or Command Prompt:

composer require phpgif/phpgif

use phpgif\GIF\GifGenerator

Without Composer

When using shared hosting, many hosting providers don't allow Composer. Use the following system to install PHP-GIF-Reborn.

1. Download the repo
2. Open the src/Gif folder
3. Copy GIFEncoder.php and GIFGenerator.php into your file
4. Paste the following code at the top of your file:

include 'GIFEncoder.php';
include 'GIFGenerator.php';

Getting Started

Create a PHP file and add these headers at the beginning of the file:

// Caching disable headers
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

// Output as a GIF image
header ('Content-type:image/gif');

// Import the GIFEncoder and GIFGenerator PHP files
include 'GIFEncoder.php';
include 'GIFGenerator.php';

On the next lines you can create a GIF image by first initializing the GIFGenerator object and creating an array with all the image frames:

// Initialize a new GIFGenerator object
$gif = new GIFGenerator();

// Create a multidimensional array with all the image frames
$imageFrames = array(
	'repeat' => false,
	'transparent' => false,
	'frames' => array(
		array(
			'image' => './images/newyear.jpg',
			'text' => array(
				array(
					'text' => 'Hello GIF frame 1',
					'fonts-color' => '#000',
					'x-position' => 140,
					'y-position' => 138
				)
			),
			'delay' => 100
		),
	)
);

Finally you generate the image and echo the results on the screen:

echo $gif->generate($imageFrames);

Example

A more complete example. You could copy/paste below code to a file and execute it in the browser to view a more complete result. As you can see it's not required to use text in your GIF image and you can add as much text per frame, and as much frames per GIF image as you like.

<?php
// Caching disable headers
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

// Output as a GIF image
header ('Content-type: image/gif');

// Include the GIFEncoder and GIFGenerator PHP files
include 'GIFEncoder.php';
include 'GIFGenerator.php';

// Initialize a new GIFGenerator object
$gif = new GIFGenerator();

// Create a multidimensional array with all the image frames
$imageFrames = array(
	'repeat' => 5,
	'transparent' => true,
	'frames' => array(
		array(
			'image' => './images/newyear.jpg',
			'text' => array(
				array(
					'text' => 'Hello GIF frame 1',
					'fonts' => './fonts/Lato-Light.ttf',
					'fonts-size' => 30,
					'angle' => 0,
					'fonts-color' => '#000',
					'x-position' => 140,
					'y-position' => 138
				)
			),
			'delay' => 100
		),
		array(
			'image' => './images/newyear.jpg',
			'text' => array(
				array(
					'text' => 'Hello GIF frame 2',
					'fonts' => './fonts/Lato-Light.ttf',
					'fonts-size' => 15,
					'angle' => 0,
					'fonts-color' => '#000',
					'x-position' => 140,
					'y-position' => 138
				),
				array(
					'text' => 'Hello GIF frame 2',
					'fonts' => './fonts/Lato-Light.ttf',
					'fonts-size' => 15,
					'angle' => 0,
					'fonts-color' => '#000',
					'x-position' => 140,
					'y-position' => 108
				)
			),
			'delay' => 100
		),
		array(
			'image' => './images/newyear.jpg',
			'delay' => 50
		)
	)
);

echo $gif->generate($imageFrames);
