Convert HTML to PDF

@Marcus-Barnet I'd examine headers set by mail client and by Qt code.

Marcus Barnet

Following your suggestion, I tried to compare both mail headers, but they look almost similar to me even if the email client seems to convert the mail text to HTML.

This is the header for the email sent by the QT code:

Received-SPF: pass (google.com: domain of pumpasdmaglie@gmail.com designates 209.85.220.41 as permitted sender) client-ip=209.85.220.41;

@Marcus-Barnet said in Convert HTML to PDF:
Content-Type: multipart/related; vs Content-Type: multipart/mixed;

There are also differences in Return-Path header but I assume this is due to not full obfuscation on your part?

I'll need to verify with google docs if this makes any difference (Content-Type), I really don't know from the top of my head.

Marcus Barnet

I was able to find nothing related to this problem!
The attachment part seems to be similar to both cases and also the base64 encoded content.

@Marcus-Barnet said in Convert HTML to PDF:

Thank you! Yes, I could try! I have all the html code store into a QString html_page variable.
What is the fastest way to convert it to QTextDocument?
QTextDocument doc;
doc.setHtml(html_page );

The web page is formatted to fit in a A4 format as it is.
I couldn't find any simple code to understand how to use QPdfWriter, by the way!

Did this not work for you?

In a program I did quickly to help with POs I generate HTML with the given info. that is stored in a QString called "html"

            QTextDocument document;
            document.setHtml(html);

            QPrinter printer(QPrinter::PrinterResolution);
            printer.setOutputFormat(QPrinter::PdfFormat);
            printer.setPaperSize(QPrinter::A4);
            printer.setOutputFileName(QStandardPaths::writableLocation(QStandardPaths::DesktopLocation) + "/" + po.purchaseOrderNumber() + ".pdf");
            printer.setPageMargins(QMarginsF(15, 15, 15, 15));

            document.print(&printer);

that puts the PO on the desktop for me.

@Marcus-Barnet So I did my research and content-type variations should not have any impact. I am afraid that is as far as I can help you with emailing.

I did other tests, too, and I also contacted the author of the SMTP library, but at the end, it seems that the problem is not easy to solve.
As a workaround, I added a simple text in the email saying something like: "Id you do not see the attachment, please read this email from your webmail or your mail client".

Thank you for your help, @artwaw
