C# Code 93 Reader Library
C# Imaging - Decode Code 93 Barcode in C#.NET

Code 93 Reading Control in C#.NET

RasterEdge is committed to supporting and developing .NET imaging solutions that can be used to automate document management and image processing applications. The barcode reader control from RasterEdge DocImage SDK for .NET utilizes the most advanced 1D and 2D barcodes scanning methods. Using RasterEdge .NET Imaging Barcode Reader control, you can easily read & decode linear Code 93 barcode from image files (PNG, TIFF, GIF, JPEG & BMP) and documents (PDF, multi-page TIFF, Excel, PowerPoint & Word).

Code 93, also known as ANSI/AIM Code 93, ANSI/AIM Code 93, Uniform Symbology Specification Code 93, is an alphanumeric, variable-length linear barcode symbology. It came into being with the purpose to provide a higher density and data security enhancement to Code 39. In the daily applications, this 1d Code 93 barcode is primarily used to encode supplementary delivery information by Canada Post.

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.
