P:Windows.Devices.Scanners.ImageScannerFlatbedConfiguration.ContrastStep |
winrt property |
Gets the step size at which the contrast levels of the data source can increase or decrease between the minimum and maximum values.
The step size to increment or decrement. The typical value is 1.
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.
