I did not dispute that. Yes, there is something missing from the documentation 
and it needs to be improved. I wholeheatedly agree with you there.

I am also saying there's a bug somewhere else in your code or in Qt. The 
problem is not the Writer, but the transformations you made before sending the 
information to the reader or the Reader itself.

I'll add that. See https://codereview.qt-project.org/215337
