A native PHP template system
What is Glide? A wonderfully easy on-demand image manipulation library
written in PHP.
Glide has an HTTP based API. Manipulate images using GET
parameters.
/img/kayaks.jpg /img/kayaks.jpg?w=500 /img/kayaks.jpg?w=500&h=600 /img/kayaks.jpg?w=500&h=600&fit=crop /img/kayaks.jpg?w=500&h=600&fit=crop&filt=sepia
So where did the idea come from? Anyone remember TimThumb?

It’s a good time for HTTP + PHP. Middleware and
PSR-7 are changing how we build applications in PHP.
Only save your original images, not the manipulations. Then request
different image sizes when they are needed.
Use GD or ImageMagick. Glide is built on the Intervention
Image library.
use League\Glide\ServerFactory; ! $server = ServerFactory::create([ 'driver' => 'imagick', ]);
Use any file storage. Glide uses the Flysystem file system
abstraction library.
Use Glide in an app, or create a separate image
server. Offload image manipulations to a separate server on larger projects
Basic Glide installation. Using out-of-the-box settings.
get('/img/users/{id}', function ($id) { ! $server = ServerFactory::create([ 'source' =>
'path/to/source', 'cache' => 'path/to/cache', ]); ! $server->outputImage( 'users/'.$id.'.jpg', [ 'w' => 300, 'h' => 400 ] ); });
get('/img/{path}', function ($path) { ! $server = ServerFactory::create([ 'source' =>
'path/to/source', 'cache' => 'path/to/cache', ]); ! $server->outputImage($path, $_GET); });
get('/img/{path}', function (Request $request) { ! $server = ServerFactory::create([ 'source'
=> 'path/to/source', 'cache' => 'path/to/cache', ]); ! $server->outputImage($request); });
get('/img/{path}', function (Request $request, Glide $glide) { $glide->outputImage($request); });

Setup Glide using S3. Free your images from the local
disk.
$server = ServerFactory::create([ 'source' => 'path/to/source', 'cache' => 'path/to/cache', ]);
$source = new Local('path/to/source'); $cache = new Local('path/to/cache'); ! $server
= ServerFactory::create([ 'source' => new Filesystem($source), 'cache' => new Filesystem($cache), ]);
$client = S3Client::factory([ 'key' => 'your-key', 'secret' => 'your-secret', ]);
! $s3 = new AwsS3Adapter($client, 'your-bucket'); $cache = new Local('path/to/cache'); ! $server = ServerFactory::create([ 'source' => new Filesystem($s3), 'cache' => new Filesystem($cache), ]);
Set a max image size. Prevent accidental resizing of massive
images.
use League\Glide\ServerFactory; ! $server = ServerFactory::create([ 'max_image_size' => 2000*2000, ]);
Prevent URL hacking by signing the image URLs. An important
security step that should always be used in production.
$builder = UrlBuilderFactory::create( 'http://example.com', 'your-sign-key' ); ! // Generate a
URL $url = $builder->getUrl('cat.jpg', ['w' => 500]); ! // Use the URL in your app echo '<img src="'.$url.'">';
$templates->registerFunction('img', function ($path, $params) { ! $builder = UrlBuilderFactory::create( 'http://example.com',
'your-sign-key' ); ! return $builder->getUrl($path, $params); });
<img src="<?=$this->img('cat.jpg', ['w' => 500])?>">
<img src="http://example.com/img/cat.jpg? w=500&token=af3dc18fc6bfb2afb521e587c348b904">
$request = Request::createFromGlobals(); $signature = SignatureFactory::create('your-sign-key'); ! try { $signature->validateRequest($request);
} catch (SignatureException $e) { // Handle error }
Resizing.
/img/kayaks.jpg?w=500 /img/kayaks.jpg?h=600 /img/kayaks.jpg?w=500&h=600 /img/kayaks.jpg?w=500&h=600&fit=contain
Cropping.
/img/kayaks.jpg?w=500&h=500&fit=crop
/img/kayaks.jpg?w=500&h=500&fit=crop&crop=left
/img/kayaks.jpg?rect=300,300,810,140
/img/kayaks.jpg?or=90
Adjustments.
/img/kayaks.jpg?bri=-25
/img/kayaks.jpg?con=25
/img/kayaks.jpg?sharp=15
Effects.
/img/kayaks.jpg?blur=10
/img/kayaks.jpg?pixel=10
/img/kayaks.jpg?filt=sepia
/img/kayaks.jpg?filt=greyscale
Output.
/img/kayaks.jpg?fm=gif /img/kayaks.jpg?fm=png /img/kayaks.jpg?fm=jpg /img/kayaks.jpg?fm=jpg&q=90
Extend! Adding your own manipulations.
Moving forward.
