Hi Klaus,
Some functions of your scanner backend are very interesting for the
Pixma backend, too. My scanner (CanoScan 9000F) also has an ir-lamp for
dust removal functions. I'm very happy that you're implementing such
functions to Sane now.
the praise should go to Michael Rickmann <[email protected]>, I'm just
pushing this upstream now ;-)
Please move the buffer functions from backend/pieusb_buffer.[ch] to e.g.
sanei/sanei_buffer.[ch]. Then I also can use your buffer functions for
the Pixma backend.
Stef, do you agree ?
It should be noted that the current SANE API (or the dust removal code
?!) isn't really prepared for two-pass scanning with dust removal. The
pieusb driver 'blocks' during the scan process because dust removal
starts after the scan is complete. This appears to the sane frontend as a
long sane_start() with an almost instantaneous transfer of scan data
in sane_read().
Unfortunately, the same is true of backends using sanei_magic- we just block :(

Hello,
I have reviewed latest changes, and I consider that the pieusb
backend is ready for inclusion since commit
e6294630553b5bcb2671537786c5107e3393ac9f on the pieusb branch of
[email protected]:kkaempf/sane-backends.git .
I suppose you'll create an account on alioth
(https://alioth.debian.org/account/register.php) so that Allan can add
you to the project.
I would be really great if you could extract the buffer bits in a
sanei_buffer, it would be an added bonus for the project. But it is a
separate issue from backend inclusion.
Many thanks for this nice work.
Allan, adding a backend requires you re-run config script on
alioth, isn't-it ?
Regards,
Stef
