Cannot set int array option (gamma-table) #69

Open arunasr opened 3 years ago

arunasr commented 3 years ago

My scanner supports customisation of colour curve table. "scanimage" utility reports this option as

   --red-gamma-table 0..255,...
        Gamma-correction table for the red band.
    --green-gamma-table 0..255,...
        Gamma-correction table for the green band.
    --blue-gamma-table 0..255,...
        Gamma-correction table for the blue band.

It is an array of integers, SANE reports option size 1024. Alas, Python demands a single-value int/long option. image How can we support value tables?
