Easy way to create gif animations from png images for laravel 5.*.

Install

Via Composer

$ composer require pomirleanu/gif-create

Usage basic php

1. Inputs:

// 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:

use Pomirleanu\GifCreate;

// ...

$gif = new GifCreate\GifCreate();
$gif->create($frames, $durations);

// Or: using the default 100ms even delay:
//$gif->create($frames);

// Or: loop 5 times, then stop:
//$gif->create($frames, $durations, 5); // default: infinite looping

3. Get/use the result:

You can now get the animated GIF binary:

$gif = $gif->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:

$gif->save("animated.gif");

Usage in laravel 5.*

Service provider should be :

Pomirleanu\GifCreate\GifCreateServiceProvider::class,

Publish needed assets (config file) :

php artisan vendor:publish --provider="Pomirleanu\GifCreate\GifCreateServiceProvider"

Note: Composer won't update them after composer update, you'll need to do it manually!

Behavior

  • 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.

Dependencies

  • PHP 5.3 (for namespace support & whatnot; noone still shamelessly uses PHP < 5.3, right?!)
  • GD (imagecreatefromstring, imagegif, imagecolortransparent)
