pqScan .NET Barcode Scanner Library supports scanning of Code 128 linear bar code in Visual Studio .NET applications. This library includes 6 well-compiled APIs that can be used to detect and decode Code 128 barcode from image source. And recognition result will be returned in array for .NET windows and web applications with no fuss.

Powerful .NET Component

.NET Code 128 barcode scanning library is completely written in Visual C#.NET. It could be added into .NET 2.0 or above versions. Both .NET applications and ASP.NET websites are supported.

This component can easily detect and read Code 128 in C#.NET and VB.NET programming. Demos are provided. Please click Scanning Code 128 in C#.NET or VB.NET to learn more.

Decoding Code 128/GS1-128/EAN-128

Code 128 is a high-density 1D barcode symbology that encodes all 128 ASCII characters. One of its subsets GS1-128 is widely used in shipping and packing industries to identify containers and pallets.

.NET barcode reader software is able to recognize and decode all Code 128 subsets for your .NET application precisely. Data information in Code 128 barcode will be decoded and returned automatically with robust APIs. No more knowledge about this barcode symbology is required from you.

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

Multi-type Barcodes Recognition

.NET Barcode Scanning Component supports recognition and reading of multiple barcodes in one image. If your image source maintains more than one Code 128, or other types of barcode besides Code 128, please use APIs below.

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

These three APIs are able to read bar code and return BarcodeResult in data array. The BarcodeResult contains both barcode type (Barcodetype) and barcode text data (Data).

Reading One Barcode from Image

To improve barcode recognition accuracy, we provide three APIs for one barcode recognition. It is suitable when there's only one barcode on your image.

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

Professional Barcode Image Scanning

pqScan has been dedicated to barcode image recognition and reading since 2009. .NET Barcode Scanner SDK is a mature and professional .NET component that allows developers to built application with high quality barcode reading functionality.

This .NET barcode reader library supports detecting and decoding of Code 128 linear bar code from images in string, stream and bitmap forms. And image file formats like bmp, jpg, jpeg, png, tiff, tif, and gif are supported. To achieve Code 128 barcode reading from PDF file, you should also use our .NET PDF to Image Converter SDK. And no matter where are the barcodes' location in the picture, our barcode scanner software can decode them out.
