C# Imaging - Decode Interleaved 2 of 5 in C#.NET

C# Interleaved 2 of 5 Barcode Recognition

The barcode reader control library toolkit from RasterEdge DocImage SDK for .NET owns two impressive Interleaved 2 of 5 barcode reading & scanning features. Firstly, quickly read one or multiple Interleaved 2 of 5 barcode(s) from both document & image files using a few lines of C# code. Secondly, specify a smaller area in the image for Interleaved 2 of 5 barcode recognition using C#.NET.

Interleaved 2 of 5, a continuous barcode type, is often used on 135 films and cartons of some products. And this barcode reader is developed under the guidance of latest established Interleaved 2 of 5 barcode standards and barcode specifications. Thus, it can be used as a tool to check whether scanned Interleaved 2 of 5 barcode is industry-standard.

Besides, this barcode reader control can also be used to read & decode other linear & 2d barcodes from document image files in C#.NET class application, like Code 39, Code 128, QR Code and UPC-A. Besides barcode reading & recognizing in Visual C#, RasterEdge DocImage SDK for .NET also contains a barcode generator add-on which can help you generate Interleaved 2 of 5 barcode using VB.NET code.

Steps to Read/Scan Data Matrix from Image/PDF/TIFF/Office File

Load an image or a document(PDF, TIFF, Word, Excel, PowerPoint).

Get a Bitmap or BasePage used to decode or read barcode.

Set the barcode reader settings.

Call the following static method in BarcodeReader.cs to read or scan barcode from Bitmap or BasePage.

  public static Barcode[] ReadBarcodes(ReaderSettings settings, BasePage page)

  public static Barcode[] ReadBarcodes(ReaderSettings settings, Bitmap image)

The barcode information will be saved in the array of Barcode object. While, if you read barcodes information from the BasePage failed, you can try as follows:

  Convert BasePage to Bitmap with higher resolution by Calling method ConvertToImage(int resolution) in the BasePage.cs:

            //Convert page to bitmap.
            //The default resolution is 96, if youo set the resolution higher, it will be better to read or scan barcode.
            Bitmap bmp = page.ConvertToImage(192);

            //  read all barcodes in the page
            Barcode[] barcodes = BarcodeReader.ReadBarcodes(settings, bmp);

            foreach (Barcode barcode in barcodes)
            {
                Console.WriteLine("Data: " + barcode.DataString);
            }

If you want to have a try, please refer to the following demo codes.

Note: When you get the error "Could not load file or assembly 'RasterEdge.Imaging.Basic' or any other assembly or one of its dependencies. An attempt to load a program with an incorrect format", please check your configure as follows:

       If you are using x64 libraries/dlls, Right click the project -> Properties -> Build -> Platform target: x64.

       If using x86, the platform target should be x86.

Interleaved 2 of 5 Barcode Reading from Image in C#

It is an easy task to read & decode one or multiple Interleaved 2 of 5 barcode(s) from image files and .NET image objects using this C#.NET barcode reader & decoder control from RasterEdge DocImage SDK for .NET. Supported raster image formats are png, jpeg, bmp, gif and tiff.

In this part, we will take Interleaved 2 of 5 barcode reading and recognition from PNG image files as examples. Using the sample C# code below, you can detect and decode all Interleaved 2 of 5 barcodes from target png images in .NET Framework applications (ASP.NET web site and Windows Forms).

Add necessary references to your C#.NET project. Right-click the project and select "Add Reference..." to locate and add the following DLLs as project references;

            //  config reader setting
            ReaderSettings settings = new ReaderSettings();
            //  define the type of barcode to scan
            settings.AddTypesToRead(BarcodeType.Interleaved2of5);

            //  read all barcodes in the document
            Barcode[] barcodes = BarcodeReader.ReadBarcodes(settings, bmp);
