Save pictures in JPEG format into QDataStream

[Eos Pengwern]

Aha; I think I see.

So if I have a QImage called 'fred', for example, I would use (following the example given in the Qt documentation for QImage::save):

QByteArray ba;
QBuffer    buffer(&ba); // QBuffer inherits QIODevice
buffer.open(QIODevice::WriteOnly);
fred.save(&buffer, "JPG")
buffer.close();

QByteArray ba;
QBuffer    buffer(&ba); // QBuffer inherits QIODevice
buffer.open(QIODevice::WriteOnly);
fred.save(&buffer, "JPG")
buffer.close();

To copy to clipboard, switch view to plain text mode 

Then if 'ds' is the data stream that the rest of my object's data is being written to, then:

ds << ba;

ds << ba;

To copy to clipboard, switch view to plain text mode 

..should complete the process.

Looks good! Thank you very much.
