I think the headline already explains what I want to know. Is there a possible way to open and save images with 16-bit with Qt? And I don\'t mean the 3*8=24bit or 4*8=32bit,
As others already mentioned, there is no format with 16 bits per component supported in Qt for now.
However there is a request opened to implement this, with a patch attached: https://bugreports.qt.io/browse/QTBUG-45858
Not sure what is the status of this, and if it will get integrated.
