Feature proposal: Add DomPdfOutput

[liedekef]

Is it possible to support dompdf as output, next to pdf and tcpdf? See https://github.com/dompdf/dompdf
It has svg support, should have no issues with utf-8 etc ...

Possibly.

I do not know DomPdf and I am currently unsure whether I want to support more Output types right within this library. But you surely could build a DomPdfOutput as a standalone enhancement to this library.

@sprain Dompdf is very popular. If I would use a PHP-based PDF converter in a project, I would eiter use TCPDF or DOMPDF, depending which renders better for the given use case.

Therefore, I think adding Dompdf as output wouldn't be a bad idea. Especially if @liedekef would create a PR :).

I would definitely consider merging a PR :)

Well, since dompdf is like "converting html to pdf", I would need to know the complete output requirements before starting to work on this. If then dompdf is able to deliver, I'll create a PR.

since dompdf is like "converting html to pdf"

In that case it‘s worth trying what happens if you feed the output of HtmlOutput to DomPdf. Maybe this already does the trick and no specific DomPdfOutput is needed?

DomPdf is usable with php-swiss-qr-bill and HtmlOutput. Changes recommended:
1)
Use FILE_FORMAT_PNG instead of FILE_FORMAT_SVG.
2)
CSS Extension:
#qr-bill-currency { float: none !important; display: inline-block; }
#qr-bill-amount { display: inline-block; }
This solves the effect mentioned in Issue #122.
