Trying to Add image as header for Every Page in PDF

I am trying to add header image , That is two images one to the left and another to the right top corner in a PDF file. These Images are seen in the first page but if there are more than one page the image is not coming . I want to display the image in every page created based on the text size input . For Example : If there are 400 words 200 will come in one page and next 200 will come in next page . But in this only the first page has the image as header and the second page doesnt. Is there any way i can insert the image on each page generated.

Hi and welcome to the forums
Could you show how you currently print the pages and header ?

Here I have attached the code:

QFile styleFile( "widget.qss" );
styleFile.open( QFile::ReadOnly );
QString hex = QString::fromLatin1( styleFile.readAll() );
styleFile.close();

QTextDocument document;

QString data = ui->teData->toPlainText();

document.setHtml(hex.append(data));

QPrinter printer;
printer.setOutputFormat(QPrinter::PdfFormat);
printer.setPaperSize(QPrinter::A4);
printer.setOutputFileName("test.pdf");
QPainter painter;
painter.begin(&printer);
document1.setHtml(hex);
painter.setBrush(Qt::transparent);
painter.drawPixmap(0, 0, 100, 100, QPixmap("img.png"));
painter.drawPixmap(200, 0, 100, 100, QPixmap("img.png"));
painter.drawPixmap(0, 100, 100, 100, QPixmap("img.png"));
painter.drawPixmap(200, 100, 100, 100, QPixmap("img.png"));
painter.end();
printer.setPageMargins(QMarginsF(15, 15, 15, 15));

document.print(&printer);

Hex variable contains the data read from the file.

File has the following data:

<!DOCTYPE html>
<html>
<head>
<style>
.logo {
width: 150px;
height: 120px;

}

.logoHeader {
height: 120px;
vertical-align: middle;
text-align: center;
}

.floatLeft { float: left; }

.floatRight { float: right; }
</style>
</head>
<body>

<img class="logo floatRight"  src="Data.gif" alt="Logo" />

<h1 class="logoHeader">REPORT</h1>

</header>

</body>
</html>

Hi
I think you need to make it part of the QTextDocument for each page
https://forum.qt.io/topic/58550/printing-pdf-with-headers-footers
as document.print does pagination by itself and as far as i know have no signals
pr page or anything that allows us to inject new HTML pr page.

I also found this
https://gist.github.com/chris-marsh/242b6229c7c8d2ed687833db3087793f
but not had time to test it.
