QPdfView doesn't render PDF file correctly.

I'm working on an application which used to display a pdf file.

#include <QPdfView>
#include <QPdfDocument>
#include <QDebug>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QPdfDocument *document = new QPdfDocument;

    document->load("E:/multipage.pdf");

    QPdfView* view = new QPdfView;
    view->setDocument(document);

    view->setPageMode(QPdfView::MultiPage);

    view->show();
}

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

It can display the pdf file, but the widget annotation was not rendered.

above picture is the pdf opened by adobe reader. The stamp is an widget annotation.

when I open the same file with qt code. The widget annotation was not rendered.Only the text is rendered.

What should I do to make it right?

Here is the pdf structure.

Thanks for your help.

Hi
I dont think stamping and extensions as such are supported.

Try online site like
https://smallpdf.com/pdf-reader

and see if that show is.
