Writing QImage data to a XML file using QXmlStreamWriter

[ProudChild]

Im building an app in a lab that uses qt as base. We need to write an QImage data to xml file, and later on read that data, we are using QXmlStreamWriter, is there a way to write QImage as a CDATA or something like that with QXmlStreamWriter?

thanks in advance.

I suggest you to use base64-encoded image data in xml.

ok, where do i start? is there a way to do that with QImages?

Use QImage operators >> and << to serialize to/deserialize from QByteArray (using QDataStream) and use fromBase64()/toBase64() methods of QByteArray to store data in base64.
Please, note that operator<< of QImage will not produce valid image data, it will only provide data to use in operator>>
