[TYPO3-dev] FAL image path in Extbase Controller

[Klaus Heuer]

Hi List,

I need the whole image path in an Extbase Controller (background: I have 
to set headerdata, example: og image tag)

Model:
    /**
      * Image
      * @var \TYPO3\CMS\Extbase\Domain\Model\FileReference
      */
     protected $image;

  /**
      * Returns the image
      *
      * @return 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference> 
$image
      */
     public function getImage() {
         return $this->image;
     }

This works in Fluid well, but how to received the image path in Extbase? 
$myObject->getImage() didn't work.

Is there a 'build in solution' or must I build my own query with mapped 
tables?

Thanks for any hints.

Klaus
