I was thinking to something like:

QImageReader imr;

for(y = 0..height)
{
imr.setClip( QRect(x, y, width, y+1));
imr.read(img);
emit dataArrived();
}

Which would be very similar to what you would if you use directly 
libpng/libjpeg/etc. The only problem is if QImageReader::read needs to reopen 
the file for each line.
