GifFrameExtractor is a PHP class that separates all the frames (and their duration) of an animated GIF

### For what ?

The class helps you to separate all the frames of an animated GIF, for example to watermark them and then to

generate a new watermarked and animated GIF.

### Usage

GifFrameExtractor is really easy to use:

**1 - Extraction:**

```php

$gifFilePath = 'path/images/picture.gif';

if (GifFrameExtractor::isAnimatedGif($gifFilePath)) { // check this is an animated GIF

    

    $gfe = new GifFrameExtractor();

    $gfe->extract($gifFilePath);

    

    // Do something with extracted frames ...

}

```

**2 - Getting the frames and their duration:**

```php

foreach ($gfe->getFrames() as $frame) {

    

    // The frame resource image var

    $img = $frame['image'];

    

    // The frame duration

    $duration = $frame['duration'];

}

```

You can also get separately an array of images and an array of durations:

```php

$frameImages = $gfe->getFrameImages();

$frameDurations = $gfe->getFrameDurations();

```

And obtain usefull informations:

```php

$totalDuration = $gfe->getTotalDuration(); // Total duration of the animated GIF

$frameNumber = $gfe->getFrameNumber(); // Number of extracted frames

var_dump($gfe->getFrameDimensions()); // An array containing the dimension of each extracted frame

var_dump($gfe->getFramePositions()); // An array containing the original positions of each extracted frame inside the GIF

```

**Option:**

You can choose if you want to get the original frames (with transparency background) or frames pasted on the first one

with the second parameter of extract() method:

```php

$gfe->extract('path/images/picture.gif', true); // Can get transparency orignal frames

```

This option is false by default. 

### About

The class reuses some part of code of "PHP GIF Animation Resizer" by Taha PAKSU (thanks to him).
