[sane-devel] PATCH: Call script per output file from scanimage in batch mode

[m. allan noah]

Simon, this is a great idea, and is also one of the last things
missing for users to switch from the (now deprecated) scanadf to
scanimage.

Is there any chance you could find the time to make your patch
compatible with the scanadf -S option? Specifically setting the
various SCAN_* environment vars? You could add your page number as
SCAN_PAGE or some such. You would need to check if scanadf cares about
the return value for the script.

If we can get scripts compatible between the two programs, I would
commit it in a heartbeat.

Thanks!
