I think so, yes. At least that's what I do in the mustek backend when the source is changed from e.g. flatbed to transparency adpater. The geometry constraints change. As mustek was in sane since the beginning I'm pretty sure that this is intentional. > The SANE document in CVS doesn't seem to specify this exactly, it only > refers to an "option changing". At least it states that valid reasons may be to change the value and the availability. So the option_descriptor must be checked by the frontend anyway. Bye, Henning
