ImageScannerFlatbedConfiguration.BrightnessStep | brightnessStep property

Gets the step size at which the brightness levels of the data source can be increased or decreased between the minimum and maximum values.

Syntax


var brightnessStep = imageScannerFlatbedConfiguration.brightnessStep;

Property value

Type: Number [JavaScript] | System.UInt32 [.NET] | uint32 [C++]

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

Remarks

If the scanner doesn't allow brightness changes, then the MinBrightness, MaxBrightness and DefaultBrightness are set to the same value-oftentimes 0, and the BrightnessStep is set to 0. Your app can determine if the scan source doesn't support brightness adjustments by reading the BrightnessStep value. If the value is greater than 0, the scan source supports brightness adjustments.
