[Qt-interest] QWebView: howto embed a QPixmap into HTML code [Solved]

[Ulf-Alexander v. Ceumern-Lindenstjerna]

Okay, after some research I managed to find a solution to my problem:

// use QByteArray to embed the images into the HTML as a base64 encoded string
QByteArray byteArray;
QBuffer buffer(&byteArray); // use buffer to store pixmap into byteArray
buffer.open(QIODevice::WriteOnly);
pixmap->save(&buffer, "PNG");
html += "<img src=\"data:image/png;base64," + byteArray.toBase64() + "\">";
webView->setHtml(html);

Works like a charm!

Cheers, Ulf
