Hi, Gerard Klaver reported a small bug in xscanimage (and quiteinsane). I don't know, whether he also informed the xscanimage maintainer, therefore I report it on sane-devel.
Problem: The size of huge images gets displayed incorrectly. For instance, the size of a 27192 x 37439 image in 8bit RGB mode is reported as 1185,07 Mbyte. Fix: Cast ints to double before multiplication. In xscanimage.c around line 464 change double size = params.bytes_per_line * params.lines; to double size = (double)params.bytes_per_line * (double)params.lines; otherwise multiplying two ints might exceed INT_MAX. bb Michael
