Class BarcodeReaderOptions

An Options class of BarcodeReader for reading many popular barcode formats from Images and PDFs.

Inheritance

public class BarcodeReaderOptions : Object

Initializes a new instance of the BarcodeReader class.

public BarcodeReaderOptions()

Toggle whether to automatically rotate barcodes or not in an ML detection. Default = true.

public bool AutoRotate { get; set; }

Minimum confidence level for ML model detection to be considered valid. The value is between (0.0, 1.0). Default value is 0.7

public double ConfidenceThreshold { get; set; }

The area of each image frame in which to scan for barcodes. A IronSoftware.Drawing.Rectangle measured in pixels.

public Rectangle CropArea { get; set; }

The barcode encoding types to read from the InputImage. By default all supported barcodes types are scanned for.

public BarcodeEncoding ExpectBarcodeTypes { get; set; }

If set to false the barcode reader will stop scanning a given image once a barcode has been found to increase performance. Default = true.

public bool ExpectMultipleBarcodes { get; set; }

A collection of image filters for image pre-processing.

public ImageFilterCollection ImageFilters { get; set; }

Max Threads for parallel. Default 4

public int MaxParallelThreads { get; set; }

The minimum number of scan-lines that must agree on a barcode result for it to be considered valid.

Increasing this reduces false positives (misreads) but may prevent detection of thin or low-quality barcodes.

Decreasing this (e.g. to 1) increases sensitivity for difficult barcodes but may introduce noise.

Default is 2.

public int MinScanLines { get; set; }

Reads barcodes from multiple images in parallel. Multiple threads will automatically be started and managed to improve performance for batch barcode reading tasks.

public bool Multithreaded { get; set; }

Attempt to remove false positive barcode reads. This can be disabled to improve performance at the cost of accuracy. Default = true.

public bool RemoveFalsePositive { get; set; }

Define how IronBarcode scans and detects barcodes in an image to read.

public BarcodeScanMode ScanMode { get; set; }

Barcode reading speed. Default = Balanced.

public ReadingSpeed Speed { get; set; }

If a Code39 barcode is detected, use the extended mode for the full ASCII character set.

public bool UseCode39ExtendedMode { get; set; }
