Hello
I have been looking at the "best way" to control film holder movement. As far
as I could tell in 1.0.6 no backend was supporting this (at least the
coolscan and the canon fs didn't).
Today I had a look at the coolscan2 project. It allows an option -frame as in:
scanimage -frame 3
My proposal is similar, but more elaborate. I think that it could also be
arranged so that it facilitates life for adf scanners. Possible commands
would be:
scanimage -number-of-frames
prints 1 for normal flatbeds,
4 or 6 for film holders
the number of frames in the aps cassette
0 or -1 if there is an adf feeder
scanimage -can-move-back
a scanner property, probably false for adf scanners
scanimage -which-frame
scanimage -goto-next-frame
fails if the last frame in the film strip or in the adf cassete
has been reached or if there are no more sheets in the adf
scanimage -goto-previous-frame
fails if already at the beginning
scanimage -goto-frame 3
This interface and an extension in the api would allow a simple integration
with other frontends.
Comments?
