GifCreator
================================
GifCreator is a PHP class to create animated GIF from multiple images
For what ?
This class helps you to create an animated GIF image: give multiple images and their duration and that's it !
Usage
1 - Creation:
// Create an array containing file paths, resource var (initialized with imagecreatefromXXX), // image URLs or even binary code from image files. // All sorted in order to appear. $frames = array( imagecreatefrompng("/../images/pic1.png"), // Resource var "/../images/pic2.png", // Image file path file_get_contents("/../images/pic3.jpg"), // Binary source code 'http://thisisafakedomain.com/images/pic4.jpg', // URL ); // Create an array containing the duration (in millisecond) of each frames (in order too) $durations = array(40, 80, 40, 20); // Initialize and create the GIF ! $gc = new GifCreator(); $gc->create($frames, $durations, 5);
The 3rd parameter of create() method allows you to choose the number of loop of your animated gif before it stops. In the previous example, I chose 5 loops. Set 0 (zero) to get an infinite loop.
2 - Get the result:
You can now get the animated GIF binary:
$gifBinary = $gc->getGif();
Then you can show it in the navigator:
header('Content-type: image/gif'); header('Content-Disposition: filename="butterfly.gif"'); echo $gifBinary; exit;
Or save it in a folder as a GIF:
file_put_contents('/myfolder/animated_picture.gif', $gifBinary);
Behavior
- The transparency is based on the first given frame. It will be saved only if you give multiple frames with same transparent background.
- The dimensions of the generated GIF are based on the first frame. If you need to resize your frames to get the same dimension, you can use this class: https://github.com/Sybio/ImageWorkshop
About
The class reuses some part of code of "GIFEncoder.class.php" by László Zsidi (thanks to him).
