.NET EAN-8 Recognition Control

Have you already know about EAN-8 1d barcode? What data information can be decoded from this barcode symbology? Users are suggested to know some basic knowledge about EAN-8 bar code.

EAN-8 was introduced for use on small packages where an EAN-13 barcode would be too large, such as on cigarettes, pencils, and chewing gum packets. It is a continuous barcode with a mandatory Modulo 10 check digit, which determines the accuracy of all EAN-8 encoded data. That is to say, wrong check digit will cause the failure of barcode reading in your .NET project. Another thing you should know about EAN-8 is its encodable data, also the result of barcode decoding. Simply, it can encode 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. So, decoded data of EAN-8 in .NET project will be digits from 0-9.

In this part, you will see nine bar code reading APIs for EAN-8 recognition for .NET windows and web applications. Firstly, you are supposed to use the one group of three APIs to define EAN-8 as desired barcode type that will be scanned and decoded from your image source. And our .NET Barcode Scanner DLL will only read and output this barcode information. Then, you can also try the second group APIs to scan the whole image and recognize all barcodes that it detects on loaded image source, in addition to EAN-8. Moreover, to improve EAN-8 barcode recognition accuracy, we provide another three APIs for one barcode recognition. It is suitable when there's only one EAN-8 barcode on your image.

The following APIs compiled in pqScan.BarcodeScanner.dll can help you implement .NET EAN-8 barcode scanning from three forms of image, including bitmap, stream, and string. For PDF EAN-8 barcode recognition, please see online tutorial: How to Read Barcode from PDF in .NET, VB.NET.

API for Defining EAN-8 Scanning

public static BarcodeResult[] Scan(Bitmap bitmap, BarCodeType barType);
public static BarcodeResult[] Scan(Stream stream, BarCodeType barType);
public static BarcodeResult[] Scan(string filename, BarCodeType barType);

API for All Barcode Types Scanning

public static BarcodeResult[] Scan(Bitmap bitmap);
public static BarcodeResult[] Scan(Stream stream);
public static BarcodeResult[] Scan(string filename);

API for One Barcode Recognition

public static BarcodeResult ScanSingle(Bitmap bitmap);
public static BarcodeResult ScanSingle(Stream stream);
public static BarcodeResult ScanSingle(string filename);
