Hi, I've just had an idea about a crazy scanner frontend:
The basic idea is to use a scanner as music instrument and translate a scan line into music notes (x-scale for differnt notes and intensity for the volume). Therefore it would be nice to have a constant y value (I don't see an interesting use for y!). So it would be great to read out that one y-line and produce MIDI notes until Ctrl-C is pressed. I'm more involved into the ALSA side of this problem and absolutely new to sane development. So my question: Is it possible to solve this (read out one line without y movement) in a frontend application? Or do I have to patch the backend part? Is there any developer information available? I've just had a look to some command line frontends, but they don't touch this point (ok, it's possible that I'm blind!). But my impression was: they only handle complete scans, which I don't want to use. Or is there a general problem in the control of scanning devices, if I have this goal ..... because they were not build for this use. Is there a counterpart to "sane_get_parameters()" for setting those parameters, like lines and pixels? Anybody out there, who can give me some hints or who can say: "Forget It!" thanks, martin
