Remarks
Your app can set the value of this property to any Int32 value between the MinContrast and MaxContrast values, and also relates to the ContrastStep value with this equation:
Contrast = MinContrast + (N * ContrastStep)
where N is a positive integer smaller than or equal to (MaxContrast - MinContrast) / ContrastStep.
The app can return the contrast level to default by setting the value of this property to DefaultContrast.
If the scanner doesn't allow contrast adjustments, MinContrast, MaxContrast and DefaultContrast are set to the same value-oftentimes 0, the ContrastStep value is 0, and the app can't set the Contrast property to a value other than DefaultContrast.
