Sorry, I missed that part: which library are we now talking about? An external one (!= Qt). Your own?

If the later: couldn't you not simply write your 8bit greyscale data into a plain vanilla char * buffer instead of trying to squeeze it back into a QImage (which apparently does not support "non-indexed 8bit greyscale" format)? Who processes that greyscale image in the end? Your own code? Or some other code you cannot modify?

Cheers,
