Installation

You can install this package easily with Composer.

Usage

Decoding

// Decode filepath to Intervention\Gif\GifDataStream::class
$gif = Decoder::decode('/images/animation.gif');

// Decoder can also handle binary content directly

Encoding

Use the Builder class to create a new GIF image.

use Intervention\Gif\Builder;

// create an empty canvas
// 
$width = 32;
$height = 32;
$loops = 0; // 0 for unlimited repetitions

// create new gif with width/height and optional
// number of repetitions of animation
$gif = Builder::canvas($width, $height, $loops);

// add animation frames to canvas
// 
$delay = .25; // delay in seconds after next frame is displayed
$left = 0; // position offset (left)
$top = 0; // position offset (top)

// add animation frames with optional delay in seconds
// and optional position offset for each frame
$gif->addFrame('/images/frame01.gif', $delay, $left, $top);
$gif->addFrame('/images/frame02.gif', $delay, $left);
$gif->addFrame('/images/frame03.gif', $delay);
$gif->addFrame('/images/frame04.gif');

// encode
$data = $gif->encode();
