-$qrCode = new QrCode('Life is too short to be generating QR codes');
+$result = Builder::create()
-
+    ->writer(new PngWriter())
-header('Content-Type: '.$qrCode->getContentType());
+    ->writerOptions([])
-echo $qrCode->writeString();
+    ->data('Custom QR code contents')
+    ->encoding(new Encoding('UTF-8'))
+    ->errorCorrectionLevel(new ErrorCorrectionLevelHigh())
+    ->size(300)

-You can pick one of these values for encoding:
 
-`ISO-8859-1`, `ISO-8859-2`, `ISO-8859-3`, `ISO-8859-4`, `ISO-8859-5`, `ISO-8859-6`, `ISO-8859-7`, `ISO-8859-8`, `ISO-8859-9`, `ISO-8859-10`, `ISO-8859-11`, `ISO-8859-12`, `ISO-8859-13`, `ISO-8859-14`, `ISO-8859-15`, `ISO-8859-16`, `Shift_JIS`, `windows-1250`, `windows-1251`, `windows-1252`, `windows-1256`, `UTF-16BE`, `UTF-8`, `US-ASCII`, `GBK` `EUC-KR`
+If you use a barcode scanner you can have some troubles while reading the
+generated QR codes. Depending on the encoding you chose you will have an extra
+amount of data corresponding to the ECI block. Some barcode scanner are not
+programmed to interpret this block of information. To ensure a maximum
+compatibility you can use the `ISO-8859-1` encoding that is the default
+encoding used by barcode scanners (if your character set supports it,
+i.e. no Chinese characters are present).
 
-If you use a barcode scanner you can have some troubles while reading the generated QR codes. Depending on the encoding you chose you will have an extra amount of data corresponding to the ECI block. Some barcode scanner are not programmed to interpret this block of information. For exemple the ECI block for `UTF-8` is `000026` so the above exemple will produce : `\000026Life is too short to be generating QR codes`. To ensure a maximum compatibility you can use the `ISO-8859-1` encoding that is the default encoding used by barcode scanners.
+### Round block size mode
+
+By default block sizes are rounded to guarantee sharp images and improve
+readability. However some other rounding variants are available.
+
+* `margin (default)`: the size of the QR code is shrunk if necessary but the size
+  of the final image remains unchanged due to additional margin being added.
+* `enlarge`: the size of the QR code and the final image are enlarged when
+  rounding differences occur.
+* `shrink`: the size of the QR code and the final image are
+  shrunk when rounding differences occur.
+* `none`: No rounding. This mode can be used when blocks don't need to be rounded
+  to pixels (for instance SVG).

+RingPHP
+=======
+
+Provides a simple API and specification that abstracts away the details of HTTP
+into a single PHP function. RingPHP be used to power HTTP clients and servers
+through a PHP function that accepts a request hash and returns a response hash
+that is fulfilled using a `promise <https://github.com/reactphp/promise>`_,
+allowing RingPHP to support both synchronous and asynchronous workflows.
+
+By abstracting the implementation details of different HTTP clients and
+servers, RingPHP allows you to utilize pluggable HTTP clients and servers
+without tying your application to a specific implementation.

+
+RingPHP is inspired by Clojure's `Ring <https://github.com/ring-clojure/ring>`_,
+which, in turn, was inspired by Python's WSGI and Ruby's Rack. RingPHP is
+utilized as the handler layer in `Guzzle <http://guzzlephp.org>`_ 5.0+ to send
+HTTP requests.

+===============
+Client Handlers
+===============
+
+Client handlers accept a request array and return a future response array that
+can be used synchronously as an array or asynchronously using a promise.
+
+Built-In Handlers
+-----------------
+
+RingPHP comes with three built-in client handlers.
+
+Stream Handler
+~~~~~~~~~~~~~~
+
+The ``GuzzleHttp\Ring\Client\StreamHandler`` uses PHP's
+`http stream wrapper <http://php.net/manual/en/wrappers.http.php>`_ to send
+requests.
+
+.. note::
+
+    This handler cannot send requests concurrently.
+
+You can provide an associative array of custom stream context options to the
+StreamHandler using the ``stream_context`` key of the ``client`` request
+option.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\StreamHandler;
+
+    $response = $handler([
+        'http_method' => 'GET',
+        'uri' => '/',
+        'headers' => ['host' => ['httpbin.org']],
+        'client' => [
+            'stream_context' => [
+                'http' => [
+                    'request_fulluri' => true,
+                    'method' => 'HEAD'
+                ],
+                'socket' => [
+                    'bindto' => '127.0.0.1:0'
+                ],
+                'ssl' => [
+                    'verify_peer' => false
+                ]
+            ]
+        ]
+    ]);
+
+    // Even though it's already completed, you can still use a promise
+    $response->then(function ($response) {
+        echo $response['status']; // 200
+    });
+
+    // Or access the response using the future interface
+    echo $response['status']; // 200
+
+cURL Handler
+~~~~~~~~~~~~
+
+The ``GuzzleHttp\Ring\Client\CurlHandler`` can be used with PHP 5.5+ to send
+requests using cURL easy handles. This handler is great for sending requests
+one at a time because the execute and select loop is implemented in C code
+which executes faster and consumes less memory than using PHP's
+``curl_multi_*`` interface.
+
+.. note::
+
+    This handler cannot send requests concurrently.
+
+When using the CurlHandler, custom curl options can be specified as an
+associative array of `cURL option constants <http://php.net/manual/en/curl.constants.php>`_
+mapping to values in the ``client`` option of a requst using the **curl** key.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\CurlHandler;
+
+    $handler = new CurlHandler();
+
+    $request = [
+        'http_method' => 'GET',
+        'headers'     => ['host' => [Server::$host]],
+        'client'      => ['curl' => [CURLOPT_LOW_SPEED_LIMIT => 10]]
+    ];
+
+    $response = $handler($request);
+
+    // The response can be used directly as an array.
+    echo $response['status']; // 200
+
+    // Or, it can be used as a promise (that has already fulfilled).
+    $response->then(function ($response) {
+        echo $response['status']; // 200
+    });
+
+cURL Multi Handler
+~~~~~~~~~~~~~~~~~~
+
+The ``GuzzleHttp\Ring\Client\CurlMultiHandler`` transfers requests using
+cURL's `multi API <http://curl.haxx.se/libcurl/c/libcurl-multi.html>`_. The
+``CurlMultiHandler`` is great for sending requests concurrently.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\CurlMultiHandler;
+
+    $handler = new CurlMultiHandler();
+
+    $request = [
+        'http_method' => 'GET',
+        'headers'     => ['host' => [Server::$host]]
+    ];
+
+    // this call returns a future array immediately.
+    $response = $handler($request);
+
+    // Ideally, you should use the promise API to not block.
+    $response
+        ->then(function ($response) {
+            // Got the response at some point in the future
+            echo $response['status']; // 200
+            // Don't break the chain
+            return $response;
+        })->then(function ($response) {
+            // ...
+        });
+
+    // If you really need to block, then you can use the response as an
+    // associative array. This will block until it has completed.
+    echo $response['status']; // 200
+
+Just like the ``CurlHandler``, the ``CurlMultiHandler`` accepts custom curl
+option in the ``curl`` key of the ``client`` request option.
+
+Mock Handler
+~~~~~~~~~~~~
+
+The ``GuzzleHttp\Ring\Client\MockHandler`` is used to return mock responses.
+When constructed, the handler can be configured to return the same response
+array over and over, a future response, or a the evaluation of a callback
+function.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\MockHandler;
+
+    // Return a canned response.
+    $mock = new MockHandler(['status' => 200]);
+    $response = $mock([]);
+    assert(200 == $response['status']);
+    assert([] == $response['headers']);
+
+Implementing Handlers
+---------------------
+
+Client handlers are just PHP callables (functions or classes that have the
+``__invoke`` magic method). The callable accepts a request array and MUST
+return an instance of ``GuzzleHttp\Ring\Future\FutureArrayInterface`` so that
+the response can be used by both blocking and non-blocking consumers.
+
+Handlers need to follow a few simple rules:
+
+1. Do not throw exceptions. If an error is encountered, return an array that
+   contains the ``error`` key that maps to an ``\Exception`` value.
+2. If the request has a ``delay`` client option, then the handler should only
+   send the request after the specified delay time in seconds. Blocking
+   handlers may find it convenient to just let the
+   ``GuzzleHttp\Ring\Core::doSleep($request)`` function handle this for them.
+3. Always return an instance of ``GuzzleHttp\Ring\Future\FutureArrayInterface``.
+4. Complete any outstanding requests when the handler is destructed.

+=================
+Client Middleware
+=================
+
+Middleware intercepts requests before they are sent over the wire and can be
+used to add functionality to handlers.
+
+Modifying Requests
+------------------
+
+Let's say you wanted to modify requests before they are sent over the wire
+so that they always add specific headers. This can be accomplished by creating
+a function that accepts a handler and returns a new function that adds the
+composed behavior.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\CurlHandler;
+
+    $handler = new CurlHandler();
+
+    $addHeaderHandler = function (callable $handler, array $headers = []) {
+        return function (array $request) use ($handler, $headers) {
+            // Add our custom headers
+            foreach ($headers as $key => $value) {
+                $request['headers'][$key] = $value;
+            }
+
+            // Send the request using the handler and return the response.
+            return $handler($request);
+        }
+    };
+
+    // Create a new handler that adds headers to each request.
+    $handler = $addHeaderHandler($handler, [
+        'X-AddMe'       => 'hello',
+        'Authorization' => 'Basic xyz'
+    ]);
+
+    $response = $handler([
+        'http_method' => 'GET',
+        'headers'     => ['Host' => ['httpbin.org']]
+    ]);
+
+Modifying Responses
+-------------------
+
+You can change a response as it's returned from a middleware. Remember that
+responses returned from an handler (including middleware) must implement
+``GuzzleHttp\Ring\Future\FutureArrayInterface``. In order to be a good citizen,
+you should not expect that the responses returned through your middleware will
+be completed synchronously. Instead, you should use the
+``GuzzleHttp\Ring\Core::proxy()`` function to modify the response when the
+underlying promise is resolved. This function is a helper function that makes it
+easy to create a new instance of ``FutureArrayInterface`` that wraps an existing
+``FutureArrayInterface`` object.
+
+Let's say you wanted to add headers to a response as they are returned from
+your middleware, but you want to make sure you aren't causing future
+responses to be dereferenced right away. You can achieve this by modifying the
+incoming request and using the ``Core::proxy`` function.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Core;
+    use GuzzleHttp\Ring\Client\CurlHandler;
+
+    $handler = new CurlHandler();
+
+    $responseHeaderHandler = function (callable $handler, array $headers) {
+        return function (array $request) use ($handler, $headers) {
+            // Send the request using the wrapped handler.
+            return Core::proxy($handler($request), function ($response) use ($headers) {
+                // Add the headers to the response when it is available.
+                foreach ($headers as $key => $value) {
+                    $response['headers'][$key] = (array) $value;
+                }
+                // Note that you can return a regular response array when using
+                // the proxy method.
+                return $response;
+            });
+        }
+    };
+
+    // Create a new handler that adds headers to each response.
+    $handler = $responseHeaderHandler($handler, ['X-Header' => 'hello!']);
+
+    $response = $handler([
+        'http_method' => 'GET',

+
+Built-In Middleware
+-------------------
+
+RingPHP comes with a few basic client middlewares that modify requests
+and responses.
+
+Streaming Middleware
+~~~~~~~~~~~~~~~~~~~~
+
+If you want to send all requests with the ``streaming`` option to a specific
+handler but other requests to a different handler, then use the streaming
+middleware.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\CurlHandler;
+    use GuzzleHttp\Ring\Client\StreamHandler;
+    use GuzzleHttp\Ring\Client\Middleware;
+
+    $defaultHandler = new CurlHandler();
+    $streamingHandler = new StreamHandler();
+    $streamingHandler = Middleware::wrapStreaming(
+        $defaultHandler,
+        $streamingHandler
+    );
+
+    // Send the request using the streaming handler.
+    $response = $streamingHandler([
+        'http_method' => 'GET',
+        'headers'     => ['Host' => ['www.google.com']],
+        'stream'      => true
+    ]);
+
+    // Send the request using the default handler.
+    $response = $streamingHandler([
+        'http_method' => 'GET',
+        'headers'     => ['Host' => ['www.google.com']]
+    ]);
+
+Future Middleware
+~~~~~~~~~~~~~~~~~
+
+If you want to send all requests with the ``future`` option to a specific
+handler but other requests to a different handler, then use the future
+middleware.
+
+.. code-block:: php
+
+    use GuzzleHttp\Ring\Client\CurlHandler;
+    use GuzzleHttp\Ring\Client\CurlMultiHandler;
+    use GuzzleHttp\Ring\Client\Middleware;
+
+    $defaultHandler = new CurlHandler();
+    $futureHandler = new CurlMultiHandler();
+    $futureHandler = Middleware::wrapFuture(
+        $defaultHandler,
+        $futureHandler
+    );
+
+    // Send the request using the blocking CurlHandler.
+    $response = $futureHandler([
+        'http_method' => 'GET',
+        'headers'     => ['Host' => ['www.google.com']]
+    ]);
+
+    // Send the request using the non-blocking CurlMultiHandler.
+    $response = $futureHandler([
+        'http_method' => 'GET',
+        'headers'     => ['Host' => ['www.google.com']],
+        'future'      => true
+    ]);
