ImageScannerFeederConfiguration.ContrastStep Property

Definition

Namespace:

Windows.Devices.Scanners

Gets the step size at which the contrast levels of the data source can increase or decrease between the minimum and maximum values.

public:
 property unsigned int ContrastStep { unsigned int get(); };

uint32_t ContrastStep();

public uint ContrastStep { get; }

var uInt32 = imageScannerFeederConfiguration.contrastStep;

Public ReadOnly Property ContrastStep As UInteger

Property Value

UInt32

unsigned int

uint32_t

The step size to increment or decrement. The typical value is 1.

Implements

ContrastStep

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.
