This is not an option that should be changed while whorking. It is to say the<br>
|
|
driverhow it has to do the calibration. If I know which scanners do need this<br>
|
|
option, I will<br>
|
|
do an automatic selection, then the shading option will be remove from the user<br>
|
|
interface.<br>
|
|
But in the moment it is a good thing.<br>
