Class QrScanMode

Define how IronQR scans and detects QR Codes in an image to read. By default, a ML model will scan the image, and a basic second scan will be run if the ML model finds none.

Syntax

public sealed class QrScanMode : Enum

QrScanMode sets how IronQR detects QR codes in an image, assigned to QrImageInput.QrScanMode or the IQrInput it implements. Auto, the default, runs a machine-learning detection model and falls back to a basic scan, which handles awkward angles and noisy photos. OnlyDetectionModel forces the ML model alone, and OnlyBasicScan uses the fast classic scan for clean, straight-on images where the model's overhead is unnecessary. The scan modes how-to compares them, and the machine-learning read example shows the model in use.

var input = new QrImageInput(bitmap, QrScanMode.Auto);

Fields

Auto

Attempt to find QR Codes using the Machine Learning model, and fallback to a basic brute-force read if none are found.
