Package: gscan2pdf
Version: 0.9.14
Severity: important
As recently as a few weeks ago, my scanner used to work with
'gscan2pdf':
% lsscsi | grep scan
[0:0:5:0] scanner UMAX UMAX S-6E V2.0 -
...but now when I scan anything, it fails.
'gscan2pdf --debug' outputs:
{...stuff deleted.}
scanimage --device-name='umax:/dev/sg1' --mode='Lineart' --source='Flatbed'
-y 279.4 -l 0 --brightness='0' --threshold='50' --resolution='300' -x 215.788
-t 0 --batch --batch-count=1
Forked PID 5345
Unknown message: scanimage: attempted to set inactive option brightness
Waiting to reap process at /usr/bin/gscan2pdf line 2751.
Reaped PID 5345
Apparently it sends an inappropriate "--brightness='0'" option, (maybe
there's no such thing for this scanner), to 'scanimage', which fails.
Downgrading to v0.9.10-1 fixes the problem, since it has no 'brightness'
option.
It's not obvious what's the best way to fix this bug. Ideally
'gscan2pdf' should somehow know enough about the scanner its calling
before it invokes 'scanimage'. If for some reason that's not feasible
then it could check for the above error -- perhaps during some hardware
initialization routine: scan a little patch, send the data to /dev/null,
and grep the standard error output helpful errors, after which it would
then know not to use certain options on certain scanners.
Hope this helps...
