TYPO3（带有extbase）流体：用绝对路径显示图像src

Question

For an XML Export I need to output the absolute path of 2 images. Image1 is located in /typo3conf/ext/app/Resources/Public/Images/image1.png and Image2 is located in /uploads/tx_extensionname/image2.png

For the life of me I cannot find a way to get the absolute paths of the images. What I tried:

<f:uri.image absolute="1" src="EXT:app/Resources/Public/Images/image1.png"/>

Which returns the following error:

Argument "absolute" was not registered.

I also tried f:uri.resource , which works for image1, but, of course, doesn't for image2 because there is no extensionName.

Any hints?

The absolute argument for the f:uri.image view helper was added only recently in TYPO3 7.6.0. See the changelog:

Feature: #64286 - Added absolute url option to uri.image and image viewHelper

The ImageViewhelper and Uri/ImageViewHelper got a new option absolute. With this option you are able to force the ViewHelpers to output an absolute url.

I'd suggest upgrading to TYPO3 7.6.

If that's not possible for you for any reason, you can extend the f:uri.image view helper. The code below is untested, but should work for 6.2 LTS (I've borrowed parts of the code from TYPO3\CMS\Extbase\Service\ImageService in 7.6):

namespace Vendor\ExtensionKey\ViewHelpers\Uri;

use TYPO3\CMS\Fluid\ViewHelpers\Uri\ImageViewHelper;
use TYPO3\CMS\Core\Utility\GeneralUtility;

class ImageViewHelper extends ImageViewHelper
{
    public function render(
        $src = null,
        $image = null,
        $width = null,
        $height = null,
        $minWidth = null,
        $minHeight = null,
        $maxWidth = null,
        $maxHeight = null,
        $treatIdAsReference = false,
        $absolute = false
    ) {
        $uri = parent::render($src, $image, $width, $height, $minWidth, $minHeight, $maxWidth, $maxHeight, $treatIdAsReference);

        if ($absolute) {
            $uriPrefix = $GLOBALS['TSFE']->absRefPrefix;
            $uri = GeneralUtility::locationHeaderUrl($uriPrefix . $uri);
        }

        return $uri;
    }
}
