• Configurable find mask setup (best mask, random mask and default mask value)

Installation

Step 1: Composer

Add the following require line to the composer.json file:

{
    "require": {
        "bushidoio/qrcode-bundle": "dev-master"
    }
}

And actually install it in your project using Composer:

php composer.phar install

You can also do this in one step with this command:

$ php composer.phar require bushidoio/qrcode-bundle "dev-master"

Step 2: Enable the bundle

Enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new BushidoIO\QRCodeBundle\BushidoIOQRCodeBundle(),
    );
}

Step 3: Enable the route

Add this to your routing configuration in app/config/routing.yml:

bushidoio_qrcode:
    resource: "@BushidoIOQRCodeBundle/Controller/"
    type:     annotation

Configuration

You can configure some options in app/config/config.yml. Those are the default values:

bushidoio_qrcode:
    cacheable: true
    cache_dir: ~
    logs_dir: ~
    find_best_mask: true
    find_from_random: false
    default_mask: 2
    png_maximum_size: 1024
    absolute_url: true
    http_max_age: 600
    https_max_age: 600

Usage examples

You can use Twig functions or filtes to create URL or BASE64 encoded images. If no parameters are used the default options for the image are size 3 (87x87 pixels) and PNG format.
