HI all,
Im using UMAX 2000p scanner and Im writing a frontend, how can i =
increase or decrease the color. I have noticed an options =
gamma-table,red-gamma-table,blue-gamma-table and green-gamma-table which =
has a size of 1024 each with value range 0 to 255. Do I have to assign =
all  the SANE_Word with the expected value(ie all the 1024/SANE_Word ). =
Will it be enough if I assign the value only to the gamma-table or do i =
have to assign the values to all the red,blue and green gamma-tables.
Thanks
Aneesh
