Re: [Gnumed-devel] packaging help needed - TWAIN, XSANE, SANE

[Jim Busser]

Can we please review the GNUmed dependencies for

        Add documents plugin > Scan page(s)

to be able to operate a scanner?

What I am not sure about is whether (in the case of SANE) GNUmed would  
itself directly access the driver, or whether GNUmed would instead  
rely on some other software (XSANE?) to talk to the driver, where the  
driver (TWAIN e.g. ExactScan / WIA / hybrid e.g. VueSCAN / SANE) will  
depend on what the scanner would support?

On Windows, might users' options include user's scanner-dependent  
choice of:

        twainmodule / TWAIN
                (GNUmed-operable)?
        or
        xsane-win32 / SANE
                (GNUmed-operable)?

On Mac, might options include user's choice of:

        XSANE / SANE
                 (GNUmed-operable)?

        or

        TWAIN SANE Interface for MacOS X / SANE
                 (GNUmed-inoperable)?

        or

        TWAIN
                (mostly GNUmed-*in*operable)?
                (except Exactscan claims to be able to
                "push resulting image files into third party
                apps that do not support the TWAIN or
                Image Capture interface themselves.)
