I'm facing a problem with displaying a QR code in a PDF file. When I try to display the QR code without PDF it works. The QR code is generated by https://github.com/SimpleSoftwareIO/simple-qrcode on to a pdf file generated by https://github.com/barryvdh/laravel-dompdf/tree/0.8.5

StudentController.php:

StudentController.php:

public function view_downlads($id){
    $pdf = PDF::loadView('Student.markscardpdf');
    return $pdf->stream();
}

学生/markscardpdf.blade.php:

Student/markscardpdf.blade.php:

{{ QrCode::size(200)->generate('hello') }}

推荐答案

您可以通过转换base64格式在image标签中使用库输出.

You can use library output within image tag by converting base64 format.

示例:

<img src="data:image/png;base64, {!! base64_encode(QrCode::format('png')->size(200)->generate('http://google.com')) !!} ">
