Symfony:无法在pdf文件中渲染图像

Question

我在Symfony项目中使用dompdf来渲染PDF

$pdfOptions = new Options();
$pdfOptions->set('defaultFont', 'Arial');
$pdfOptions->setIsPhpEnabled(true);
$pdfOptions->setIsRemoteEnabled(true);
$dompdf = new Dompdf();
$dompdf->setOptions($pdfOptions);
$dompdf->loadHtml($html);
$dompdf->render();
$dompdf->stream("mypdf.pdf");

相同的图片显示在网页上，但不是pdf格式。我错过了什么？

Answer 1

这对我有效

$options = new Options();
$options->setIsRemoteEnabled(true);
$pdfInvoice = new Dompdf($options);
$body = $this->renderView('App/Payments/invoice.html.twig');
$pdfInvoice->loadHtml($body);
$pdfInvoice->setPaper('A4');
$pdfInvoice->render();
$pdfInvoice->stream();
return new Response($pdfInvoice->output());

还可以在模板中设置绝对路径，例如

<img src="{{ asset('assets/img/logo.png', absolute=true) }}">
