[sane-devel] Epson perfection 660 usb - problem with lineart scanning - snapscan backend

[Frédéric Leroy]

Hello,

When I try to scan in lineart mode, it makes garbage on output. The scan
seems "misaligned".
But if I first make a scan in gray or color mode, and then switch to
lineart, it works !
It seems the snapscan backend forget to initialize something in lineart
mode.
