Hello,
here are the features I think next revision of SANE's API should
contain:
There should be at least these user visible features:
- new image formats such as jpeg
- new frame types such a IR
- warming up support
- a way to tell user that the scan is uncalibrated (for sheet-fed
scanners
not yet calibrated, or if calibration is not developed).
- a mean to require an external calibration sheet from the user in the
case
of sheet-fed scanners' calibration
Useful but non-blocking:
- better backend version reporting (for meta backends case).
- capability reporting, for instance telling that some feature (gray
scan,
line art, ...) is emulated would allow a frontend to choose it's own
emulation.
-better semantics for sane_cancel()
Internal improvements that could be nice to have:
- defining an enum SANE_State={idle, scanning, ... } which would help to
write code in sanei_* functions and factor some code out of backends
There have been talks about improving the API for more than 6 years
now, and
nothing conclusive has come up. I hope a good compromise can be reach soon.
Maybe deciding of the features to add first would help. We could care of the
technical problems after.
Regards,
Stef
