QTextDocument don't print images with QPrinter

Deymos

Hello
I'm making an interactive report generator based on RichText handling and editing, I have content with text, tables and images, my QML part is TextArea, and in C++ QQuickTextDocument and QTextDocument
When I paste html into TextArea, all the images of the table and text are visible, but when I give it to QPrinter and output the preview to QPrintPreviewDialog, I have there are no images, here are my 2 approaches for adding images. In the first case, I converted to base64 and stuffed it into Html, but it doesn't work.:

void ReportBuilder::addInlineImageElement(const QImage &image, qreal width, qreal height)
{
    QString style;
    if (width > 0) style += QString("width:%1px;").arg(width);
    if (height > 0) style += QString("height:%1px;").arg(height);
    if (width == 0 && height == 0) style += "max-width:100%;height:auto;";
    QString imgTag = QString("<img width='%1' src='data:image/png;base64,%2'/>")
                     .arg(width)
                     .arg(imageToBase64(image));
    append(imgTag);
}

QString ReportBuilder::imageToBase64(const QImage &image)
{
    QImage scaled = image.scaled(640, 640, Qt::KeepAspectRatio, Qt::SmoothTransformation);

    QByteArray ba;
    QBuffer buffer(&ba);
    buffer.open(QIODevice::WriteOnly);
    scaled.save(&buffer, "PNG");
    return QString::fromLatin1(ba.toBase64());
}

My second way is to add my images to the QTextDocument resources, I generate a QUrl, send a QUrl and a QImage to a model that inserts html into the QTextDocument, but before that it registers the images, but for some reason it doesn't work either:

void ReportBuilder::addImageElement(const QImage &image, qreal width, qreal height)
{
    QImage scaled = image.scaled(640, 640, Qt::KeepAspectRatio, Qt::SmoothTransformation);
    m_imageCounter++;
    QString imageName = QString("image_%1.jpg").arg(m_imageCounter);
    QString resourceUrl = QString("cid_%1").arg(imageName);
    QUrl imgUrl(QString("myimg://%1").arg(resourceUrl));

    m_images.insert(imgUrl, scaled);

    QString imgTag = QString("<img src=\"%1\"/>").arg(imgUrl.toString());
    qDebug()<<imgTag;
    m_html.append(imgTag);
}

void ReportEditorModel::insertReport(const QString &html, const QMap<QUrl, QImage> &images)
{
    QTextDocument *doc = textDocument();
    if (!doc) {
        qWarning() << "No document available to insert Report.";
        return;
    }

    for (auto it = images.constBegin(); it != images.constEnd(); ++it) {
        doc->addResource(QTextDocument::ImageResource, QUrl(it.key()), it.value());
    }

    QTextCursor cursor = textCursor();
    QString wrappedHtml = QString("<div style='"
                                  "margin-left:%1px;"
                                  "margin-right:%2px;"
                                  "margin-top:%3px;"
                                  "margin-bottom:%4px;'>"
                                  "%5"
                                  "</div>")
                              .arg(m_leftMargin)
                              .arg(m_rightMargin)
                              .arg(m_topOffset)
                              .arg(m_bottomOffset)
                              .arg(html);
    // cursor.movePosition()
    cursor.insertHtml(wrappedHtml);
    QPrinter printer(QPrinter::HighResolution);
    QPrintPreviewDialog preview(&printer);
    connect(&preview, &QPrintPreviewDialog::paintRequested, this, [this, doc](QPrinter *printer){doc->print(printer);});
    preview.exec();
}

Here is my curent html:

"<div style='margin-left:85.0394px;margin-right:85.0394px;margin-top:85.0394px;margin-bottom:85.0394px;'>
<div style='font-size:10pt;'></div>
<hr />
<div style='font-size:16pt;'>Image 1.jpg</div>
<hr />
<div style='font-size:10pt;'></div>
<img src=\"myimg://cid_image_1.jpg\"/>
<div style='font-size:10pt;'></div>
<hr />
<div style='font-size:16pt;'>Info</div>
<hr />
<div style='font-size:10pt;'>Name: Image 1.jpg</div>
<div style='font-size:10pt;'>Size: 1824x446</div>
<div style='font-size:10pt;'>Resolution: 623 dpi</div>
<div style='font-size:10pt;'>Bit depth: 24 bit(s)</div>
<div style='font-size:10pt;'>Creation time: 14:24:07 03.09.2024</div>
</div>"

Any ideas how to make it work?
Currently on Qt 6.2.0, but on 6.5.3 same situation.
