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.
