Question

Does anyone know if it is possible to use an image generated with KnpSnappyBundle inside a webpage?
I am able to render an image from html and send it as a response to the client:

    $html = $this->renderView('YOPYourOwnPoetBundle:thePoet:poemJPG.html.twig', array(
      'poem'  => $customizedPoem,
    ));

    $data = $this->get('knp_snappy.image')->getOutputFromHtml($html);

But I can’t seem to find how to use this image inside a html response. How should I use “$data”?

Thanks.

Answer 1

You might store the image on the filesystem and reference to it as usual.

If you don’t want to store the image you can always write a controller which would:

• create a new Response object
• set the content type (to any image content type)
• set the content to contents of $data
• return that response

This way you could generate images on the fly.
