Class BinarizationMethod

Methods for binarizing images.

Inheritance

System.Object

BinarizationMethod

Namespace: IronBarCode.Internals

Assembly: IronBarCode.dll

Syntax

public sealed class BinarizationMethod : Enum

BinarizationMethod selects how IronBarcode converts a grayscale image to black and white before reading, which sharpens the contrast a decoder relies on. It is set on BinaryThresholdFilter.BinarizationMethod or passed to that filter's constructor. Otsu computes a threshold from the image histogram and adapts to uneven lighting, while Simple applies a fixed threshold value for fast, predictable results on clean scans. The image orientation correction how-to covers preprocessing filters.

var filter = new BinaryThresholdFilter(BinarizationMethod.Otsu);
