## BarCodeReader class

**Namespace:** `Aspose.Barcode.Recognition`


BarCodeReader encapsulates an image which may contain one or several barcodes, it then can perform ReadBarCodes operation to detect barcodes. This sample shows how to detect Code39 and Code128 barcodes.


## Constructors

| Name | Description |

| [__construct](#constructor) |  |

## Methods

| Name | Static | Description |
| --- | --- | --- |
| [containsAny](#containsany) | No | Determines whether any of the given decode types is included into |
| [exportToXml](#exporttoxml) | No | Exports BarCode properties to the xml-file specified |
| [importFromXml](#importfromxml) | Yes | Import BarCode properties from xml file |
| [init](#init) | No |  |
| [setBarCodeImage](#setbarcodeimage) | No | QualitySettings allows to configure recognition quality and speed manually. You can quickly set up QualitySettings by embedded presets: HighPerformance, NormalQuality, HighQuality, MaxBarCodes or you can manually configure separate options. Default value of QualitySettings is NormalQuality. |
| [setBarCodeReadType](#setbarcodereadtype) | No | Sets SingleDecodeType type array for recognition. Must be called before readBarCodes() method. This sample shows how to detect Code39 and Code128 barcodes. |

## Properties

| [BarCodeDecodeType](#barcodedecodetype) | Read-only |  |
| [FoundBarCodes](#foundbarcodes) | Read-only | Reads BarCodeResult from the image. Value: The recognized BarCodeResult array |
| [FoundCount](#foundcount) | Read-only | Gets recognized barcodes count This sample shows how to read barcodes with BarCodeReader Value: The recognized barcodes count |
| [Timeout](#timeout) | Read/Write | Gets the timeout of recognition process in milliseconds. |
