Remarks
If the scanner doesn't allow contrast changes, then the MinContrast, MaxContrast and DefaultContrast are set to the same value-oftentimes 0, and the ContrastStep value is set to 0. Your app can determine if the scan source doesn't support contrast adjustments by reading the ContrastStep value. If the value is greater than 0, then the scan source supports contrast adjustments.
