I have during my port of the SnapScan backend (v0.6) to the
Amiga found two errors.

The first error is that there seems to be a difference in the
number of lines returned by sane_get_parameters and the number
of lines actually send during scanning. In a color scanning,
for example the number returned by sane_get_parameters was
682, but the actual number of lines was 683 (I have the
debugging output).

For B/W scanning (LineArt) it is worse. The number returned
by sane_get_parameters was 590 (this is approximately the
correct line number for that scanning), but the actual number
of lines was 197 (note that 3 times 197 is 591 which is again
one more than returned by sane_get_parameters).

The second error is also in sane_get_parameters. The format
field is not set if you are scanning LineArt.
