ZBar, it only takes Y800 or 8bpp gray to the barcode scanning functions.

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,
