Hi Zhixing, hi list,

as explained in my last mail, only color mode works currently. No
calibration yet. And quite some bugs are still left. scanning with
'scanimage --mode Color > image.pnm' should work, and result in a
colored image.pnm and a (more or less) grey raw.pnm, divided in three
columns(one per color).

I am glad to see it working that well, i feared more stuck scanning
heads, as happens here sometimes.

Currently i am splitting the register initialization in movement and
optical parts. This will hopefully lead to a unified way to initialize
the scanner for normal scanning as well as for calibration and ease
integration of other scanners. I will send another patch when i am
finished with that.

Regards,
  Pierre
