Convert HTML to PDF

Marcus Barnet

@Marcus-Barnet
I will throw this in. I do not know if it is right/will help, but....

I previously suggested you use the supported/supplied Qt WebEngine, not Qt WebKit. But for whatever reason you have gone down the WebKit route :) I do not compile anything Qt (Linux). For Windows I do not know whether you have to compile or whether you download already-built. I gather WebEngine requires MSVC, not MinGW, but that seems to be what you are using anyway.

Web Engine uses the chromium engine. From @AlexMaly's post, I'm thinking/hoping this would do the necessary "chrome" facility for you, and access external URLs without problem?

You would have to check. I leave you with this possibility....

I didn't use WebEngine because I thought that WebKit was easier! But it is not working as expected, so I'll give it a try! :)
I think I should use this one: https://doc.qt.io/qt-5/qtwebengine-webenginewidgets-html2pdf-example.html as an example and make it fit my needs, is it correct?

Thank you!

Indeed. I didn't know that example existed. Looks like what you are wanting to do, so seems a good starting point!

@Marcus-Barnet I will try to build basic webkit browser and check that for you later today. You got me curious. To all my knowledge and experience this should work just fine.

@Marcus-Barnet Hi,
I got some spare time right now and this is the result:

Code:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

#include <QtWebKitWidgets>
#include <QtPrintSupport>

{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
    QWebPage *page;
};
#endif // MAINWINDOW_H

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    page = new QWebPage(this);
    page->mainFrame()->setHtml("<table align=\"center\" border=\"0\" style=\"border-collapse: collapse; width: 21cm; height: 29 cm;\"> <tbody> <tr> <td style=\"width: 100%;\"> <table border=\"0\" style=\"height: 146px; width: 100%; border-collapse: collapse; margin-left: auto; margin-right: auto;\"> <tbody> <tr style=\"height: 0px;\"> <td style=\"width: 50%; height: 146px; text-align: center;\" rowspan=\"4\"><img width=\"200\" align=\"center\" src=\"http://www.robo-dyne.com/pics/pump_logo.png\" alt=\"\" /></td>");
    ui->view->setPage(page);
    QPrinter *printer = new QPrinter(QPrinter::HighResolution);
    printer->setPageSize(QPrinter::A4);
    printer->setOutputFormat(QPrinter::PdfFormat);
    printer->setOutputFileName(QFileDialog::getSaveFileName(this,"Save location",QStandardPaths::writableLocation(QStandardPaths::DocumentsLocation)));
    page->mainFrame()->print(printer);
    delete printer;
}

MainWindow::~MainWindow()
{
    delete ui;
}

Resulting pdf file is here: https://trollnet.com.pl/dwn/webkitTest.pdf

I'd say it works?

EDIT:
UI has one QWidget in the grid layout promoted to QWebView (named, surprisingly, view).
I did additional tests where I removed the displayed part (which was added only to test the page anyway) and resulting pdf file is exactly the same, so we can exclude presence of QWebView form having any impact. QWebPage rendering and printout works perfectly fine with the sample you provided.

I really do not know what to say, but I tried your code and it doesn't work for me!
It doesn't display the image in the PDF file.

Marcus Barnet

it's strange because everything else works fine, but the images are not displayed.

Marcus Barnet

@AlexMaly said in Convert HTML to PDF:

We had the same problem and while webkit is viable option it does not support everything we needed.
We tried a few options, but the best result was produced with using chrome:
It can do it in headless mode
google-chrome --headless --disable-gpu --print-to-pdf=file1.pdf http://www.example.com/

So if you could make sure chrome is installed on your system, this would be an approach I recommend.

This solution works and it is able to generate the PDF by including also the images, but I can't scale the result PDF.
I need to fit all the content in a A4 format and to do so I need to scale the print to 93%. It seems that chrome doesn't provide this feature.

Marcus Barnet

At the moment, I solved the conversion problem by using wkhtmltopdf.

However, I was trying to generated a PDF file to be able to send it by email as an attachment since sometimes the HTML webpages are blocked by the antivirus (I guess) and they cannot be read by the user.
I was thinking to solve the problem by sending PDF files instead of HTML, but the attachments keep to be blocked on some smartphones!!

artwaw

@Marcus-Barnet That, I believe, is a problem with settings of the said smartphone mail client or account and I am not sure if you can do anything to prevent that.
Ugly solution might be to ditch pdf and render a4 size png image and include that as an attachment (but I am totally not sure if that would work with mail filters).

Marcus Barnet

But it's strange because if I sent the same PDF file as attachment by using my mail client, then they receive it.

The problem occurs only when I send it by my QT application.

artwaw

@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:

@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
