[sane-devel] Could XSane process the threshold while lineArt scan?

[eagleskycloud]

Hi,

I  have a doubt that who in charge of  processing the threshold while
lineArt scan.XSane or my driver? If XSane could process the threshold, how
could my drvier to do?
     My driver process threshold while lineArt scan now. If XSane could
process threshold, my driver would get simple.

Thank you.
