    Greetings,

    I'm running RH 6.2 and using the supplied version of Gimp and sane-1.0.1-4. I
    have a problem getting output from this combination that comes close to the
    quality of the output I get using the supplied Windows Twain interface (
    VistaScan ) that came with my UMAX Astra 1220S.

    The problem is difficult to explain but if you look at these jpegs I think you
    can see what I mean. There is a faint line of pixels on the xscanimage
    captured image and it's hard to see here but the uniformaty of the pixels on
    the vistascan captured image is much smoother than that of xscanimage.

    Both images are scanned using the same source at 300 dpi. I've used whatever
    default settings there are with each interface.

    Am I missing something here?
    Do I just not know how to use the interface to get good results?
    Is there some tweaking of my setup that must be done?

    I'd really like to solve this once and for all so that I don't have to do all
    my scanning from Windows and all my editing from Linux. Doing everything from
    Linux would be much better.

    Any help would be great.

    Cheers,
