C# Imaging - Scan ITF-14 Barcode in C#.NET


C# Code to Quickly Read ITF-14 Barcodes on Full Page Images & Documents. Support Read barcode from PDF in C#.




C#.NET ITF-14 Recognition Overview



RasterEdge .NET Barcode SDK seamlessly integrates the creation, detection and decoding of linear and 2D barcode symbols with the advanced RasterEdge .NET Imaging SDK technology. RasterEdge is the most advanced and comprehensive imaging SDK vendor and is leading the barcode industry in both speed and accuracy for reading and writing nearly 20 different barcode types and sub-types. RasterEdge Barcode Reader SDK has the ability to find barcodes in entire or specific region of document image files and return barcode data with completely accuracy using Error Correcting Codes (ECC).

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.
