[a feature request] Can't set the pdf file direction to RTL

[majebry]

What is the expected behavior?

I should be able to customize the exported pdf direction to RTL

What is the current behavior?

The method setRightToLeft(true) works when generate Excel file but does not work when the exported file is PDF.

What are the steps to reproduce?

1. Load any of the pdf packages mpdf, dompdf or tcpdf
2. set the direction of the generated file by the method setRightToLeft(true)
3. Try to generate pdf file using phpspreadsheet

Which versions of PhpSpreadsheet and PHP are affected?

PHP 7.3.6
PHPSpreadsheet 1.8.1

It seems that the method that changes the pdf direction in mpdf is $pdf->SetDirectionality('rtl'); but I couldn't customize it through phpspreadsheet

@majebry
can you tell me how you did it please

I will work on a solution for this. In the meantime, if all the sheets that you want printed are RTL, you can get the result you want with MPDF by creating and using a class which extends it:

class Mpdf2 extends Mpdf
{
    protected function createExternalWriterInstance(array $config): \Mpdf\Mpdf
    {
        $x = new \Mpdf\Mpdf($config);
        $x->setDirectionality('rtl');
        return $x;
    }
}
