Using It

Simple URL manipulation e.g.
http://thumbor/unsafe/150x400/smart/http://server/image.jpg
PHP - using composer:

"99designs/phumbor": "dev-master"

$server = 'http://127.0.0.1:8888';
$secret = '';
$url = 'http://remote-server.com/image.jpg';

$thumbor = Thumbor\Url\BuilderFactory::construct($server, $secret);

// Just output the original image
$src = $thumbor
    ->url($url)
    ->addFilter('strip_icc')
    ->resize(120,120);

echo "<img src=\"$src\"";

Resampling

460 x 307

96kb

39kb

->addFilter('strip_icc')
->addFilter('format(webp)');

32kb

30kb

->addFilter('strip_icc');

Face Detection

Meta URL

http://thumbor/unsafe/meta/smart/{URL}

Requires OpenCV

/debug

Smart Crop

$thumbor
    ->url($url)
    ->smartCrop(true)
    ->resize(150,400);

$thumbor
    ->url($url)
    ->resize(150,400);

Security

HMAC with SHA1 signing

http://thumbor/unsafe/300x200/smart/path/to/image.jpg

Becomes:

http://thumbor/12345678923456789012345678/300x200/smart/path/to/image.jpg

Requires secure key specified in config.

Running it

Python Tornado - single port/process
Scale out by running multiple instances
Reverse proxy to it using nginx (or Varnish!)

upstream backend  {
  server 127.0.0.1:8000;
  server 127.0.0.1:8001;
  server 127.0.0.1:8002;
  server 127.0.0.1:8003;
}

server {
  listen      443;
  server_name thumbor.mysite.com;

  # SSL certificates to use on secure connections
  ssl on;
  ssl_certificate	/etc/nginx/ssl/certificate.crt;
  ssl_certificate_key   /etc/nginx/ssl/server.key;

  # Forward requests to thumbor.
  location / {
    proxy_pass         http://backend;
    include            /etc/nginx/proxy.conf;
  }
}

Other stuff
