    My suggestion was simply QImageReader ppmReader(io, "ppm"), to let it read directly from the QProcess iodevice. Then there's no need to write your own loop.
    
    Would that not work? (I'm not sure what happens if we have to wait for more data to be available, maybe QImageReader isn't ready for that....)
