Does this mean "move to frame 3 and then scan an image" or just "move to frame 3"? > My proposal is similar, but more elaborate.

If you want to have these features, I propose to write a new frontend (probably based on scanimage) which can be added to sane-frontends. > This interface and an extension in the api would allow a simple integration > with other frontends. The SANE API won't be changed in the current version 1. Maybe this is an option for version 2. I don't understand the idea of some of these options, especially the options that only return information. However, I don't own a film scanner so I'm not the right person to judge this. If I'm completely wrong and the options you described can be set before a scan as usual, I don't see a problem to implement them as the normal SANE options. Bye, Henning
