Class BinarizationMethod
Methods for binarizing images.

Assembly: IronBarCode.dll
Syntax
public sealed class BinarizationMethod : EnumBinarizationMethod 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.
