How do I get advanced options to show up in xcam/xscanimage as a
separate page? The screen dump on the web site shows a GUI with index
tabs showing advanced options. I tried doing what the other drivers
did -- had a group with the SANE_CAP_ADVANCED capability set, but it
just makes the options in the group invisible when running xcam.
Xscanimage does allow controlling if the advanced options are shown.
Am I missing something or does this feature not work? (I'm using
Sane 0.5 by the way, I haven't upgraded to 0.6).
How do I handle a function that returns a non-graphical response from
the camera (e.g. ask the camera to return the number of stored
images or battery status)? I had a few ideas:
- return a "fake" image that has a representation of all of the camera
settings (similar to the LCD display on the camera)
- simply send the info as text to standard output (ugly)
- call functions in the gtk library to display it in a dialog box
(probably not a good thing for a back end to do)
