NOTE: This is a fork of Clément Guillemain's nice GifCreator class, with some API changes (class rename, new & updated methods, more flexible (and robust) parameter handling etc.), better error handling, several small corrections, code cosmetics & other improvements scattered all across.
AnimGif is a PHP class to create animated GIFs -- just list the source images (in various forms), and that's it!
// Use an array containing file paths, resource vars (initialized with imagecreatefromXXX), // image URLs or binary image data. $frames = array( imagecreatefrompng("/../images/pic1.png"), // resource var "/../images/pic2.png", // image file path file_get_contents("/../images/pic3.jpg"), // image binary data "http://thisisafakedomain.com/images/pic4.jpg", // URL ); // Or: load images from a dir (sorted, skipping .files): //$frames = "../images"; // Optionally: set different durations (in 1/100s units) for each frame $durations = array(20, 30, 10, 10); // Or: you can leave off repeated values from the end: //$durations = array(20, 30, 10); // use 10 for the rest // Or: use 'null' anywhere to re-apply the previous delay: //$durations = array(250, null, null, 500);
2. Create the GIF:
$anim = new GifCreator\AnimGif(); $anim->create($frames, $durations); // Or: using the default 100ms even delay: //$anim->create($frames); // Or: loop 5 times, then stop: //$anim->create($frames, $durations, 5); // default: infinite looping
3. Get/use the result:
You can now get the animated GIF binary:
$gif = $anim->get();
...and e.g. send it directly to the browser:
header("Content-type: image/gif"); echo $gif; exit;
Or just save it to a file:
- Transparency is based on the first frame. [!!NOT VERIFIED: "It will be saved only if you give multiple frames with the same transparent background"]
- The dimensions of the generated GIF are based on the first frame, too. If you need to resize your images to get the same dimensions, you can use this class: https://github.com/Sybio/ImageWorkshop.
