Image 带liipImagineBundle的动态滤波器

我正在使用liipImagineBundle，并试图将过滤器直接应用到控制器中

在文档中，我找到了两个部分，其中解释了如何从控制器使用liipImagineBundle。这个

我按照“将控制器作为服务使用”中的说明进行了测试，它可以正常工作，问题是我不知道如何访问过滤器设置来修改它

liip_imagine:
driver:               gd
web_root:             %kernel.root_dir%/../web
data_root:            %kernel.root_dir%/../web
cache_mkdir_mode:     0777
cache_prefix:         /media/cache
cache:                web_path
cache_clearer:        true
data_loader:          filesystem
controller_action:    liip_imagine.controller:filterAction
formats:              []
filter_sets:
    my_thumb:
        filters:
            crop: { start: [0, 0], size: [200, 150] }
    my_paste:
        quality: 90
        filters:
            paste: { start: [30, 60], image: ../web/uploads/images/firma.jpg }

第二，真的，我不明白他说“使用自定义数据加载器…”

在本例中，他仅修改ImageControl类（Liip\ImageBundle\Controller）中的filteraction（）方法。我想知道如何动态修改该方法？例如，从我的控制器indexAction（）

我也读过这篇文章，@NSCoder说“你可以使用内置的过滤器并修改它们的配置。”但我不明白

我已经找了好几天了，但我还没有找到一个可以开始的例子。

我找到了另一个LiipImagineBundle主题（），它帮助我做了我想做的事情

这里我留下了我用来动态应用过滤器的代码

public function indexAction()
{

    $container = $this->container;

    # The controller service
    $imagemanagerResponse = $container->get('liip_imagine.controller');

    # The filter configuration service
    $filterConfiguration = $container->get('liip_imagine.filter.configuration');

    # Get the filter settings
    $configuracion = $filterConfiguration->get('my_thumb');

    # Update filter settings
    $configuracion['filters']['crop']['size'] = array(50, 150);
    $configuracion['filters']['crop']['start'] = array(10, 10);
    $filterConfiguration->set('my_thumb', $configuracion);

    # Apply the filter
    $imagemanagerResponse->filterAction($this->getRequest(),'uploads/images/logo.jpg','my_thumb');

    # Move the img from temp
    $fileTemporal = new File('media/cache/my_thumb/uploads/images/logo.jpg');

    $fileTemporal->move('uploads/images/', 'mini-logo.jpg');
