dompdf - PDF file corrupt when FE compressionLevel is set

I have an extbase extension where I have a createPdfAction in which I create a PDF from the current view.

looks kinda like this:

    $html = $this->view->render();
    $dompdf->setPaper('A4', 'portrait');
    $dompdf->loadHtml(utf8_decode($html));

    $dompdf->render();
    $dompdf->stream($this->clearString('filename.pdf');
    exit;

Works great, but if i set the FE compressionLevel e.g. to 5 in the install tool - the PDF File which is created is now corrupt and can't be opened.

I even tried to turn off the compression by dompdf itself:

$dompdf->stream($this->clearString('filename.pdf',array("compress" => 0));

But that also didn't work

dompdf 0.8.0

TYPO3 8.7.1

php 7

Solution

  • Thanks to Jost:

    Adding header('Content-Encoding: gzip') fixes the problem.
