Hello I would like to know is the file plustek-s.c used in the plustek backend. Its just have abstract functions no logic in functions returns some values in every function. Can I copy plustek-s.c for a new backend to start with.
To start with a new backend. what are the things. the sane document how to write a backend is not enough. Tell me if i am right. lets say backend name is epson1001 1. create epson1001.c in backend directory [have minimum methods in it. sane_init, sane_read etc.] 2. add epson1001 in BACKENDS in configure file Is that it.? will sane go through this backend, though it may now work. i mean when i say scanimage -L will it read the epson1001 library. Is there any specific file to add backend name in the backends directory or source tree of sane-backend.x.y.z for getting started, i would like to have image file read from disk in sane_read() function and return to front end. sort of imitating, as if its scanning from real device. thanks Rayudu -- Kondala Rayudu Addagarla -------------- next part -------------- An HTML attachment was scrubbed...

Ideally the backend should set the size depending on the model; the 2480 has a piece of plastic you use to hold negatives and slides, and lets you scan two slides or three negatives at once. The 2580 has an auto film feeder built into the lid, and I believe it scans 1 negative at a time. For slides their is a plastic guide that lets it scan 1 slide. The size does need to be restored to the previous value for 2480 users, and if it is possible to distinguish between the two scanners, then the size should be selected based on the model. Simon
