How to Scan ITF-14 in C# & VB.NET

By using the following C# sample code in your Visual Studio .NET barcode recognition application, you can easily decode and read ITF-14 barcode from a local image file. Certainly, you may also have a try with provided C#.NET APIs to recognize ITF-14 linear barcode from an image string or a bitmap of image file.

public void ScanITF14FromFile(string filename)
{
  // Free C# demo code for reading ITF-14 1d barcode from a local image file.
  BarcodeResult[] results = BarCodeScanner.Scan(filename, BarCodeType.ITF14);

  // Free C# APIs for reading ITF-14 1d barcode from an image stream or a bitmap of image.
  // public static BarcodeResult[] Scan(Bitmap bitmap, BarCodeType barType);
  // public static BarcodeResult[] Scan(Stream stream, BarCodeType barType);

  foreach (BarcodeResult result in results)
  {
    Console.WriteLine(result.BarType.ToString() + "-" + result.Data);
  }
}

In addition to specify a barcode type to decode, you can directly use the following C# demo code to implement more accurate barcode scanning and reading. And this method is suitable when there's only one ITF-14 barcode on your image source.

Bitmap bmp = new Bitmap("YourImagePath");
BarcodeResult barcode = BarCodeScanner.ScanSingle(bmp);
Console.WriteLine("barcode data:{0}.", barcode.Data);

Different from above C#.NET class code which defines ITF-14 as the only barcode type to be decoded, the following VB.NET sample code can be used to detect and read all barcode symbologies from loaded image file. Respective APIs for ITF-14 decoding from image stream or bitmap of image are still offered.

Public Sub ScanAllFromFile(ByVal filename As String)
  ' Free Visual Basic class code for decoding ITF-14 barcode from a local image file.
  Dim results() As BarcodeResult = BarCodeScanner.Scan(filename)

  ' Free Visual Basic APIs for decoding ITF-14 barcode from an image stream or a bitmap of image.
  ' public static BarcodeResult[] Scan(Bitmap bitmap)
  ' public static BarcodeResult[] Scan(Stream stream)

  Dim result As BarcodeResult
  For Each result In results
    Console.WriteLine(result.BarType.ToString() + "-" + result.Data)
  Next
End Sub

For single ITF-14 barcode scanning and reading in VB.NET project, please use the following VB.NET demo code.

' Used to improve barcode decoder accuracy when there's only one ITF-14 on your image.
Dim bmp As Bitmap = New Bitmap("YourImagePath")
Dim barcode As BarcodeResult = BarCodeScanner.ScanSingle(bmp)
Console.WriteLine("barcode data:{0}.", barcode.Data)

User-defined ITF-14 Reading Methods

By using well-developed .NET APIs, C# and VB.NET programmers may choose to read ITF-14 barcode type only or read all barcodes from image source. As you see, the above free demos explain for each.

Support Rotated ITF-14 Barcode Decoding

If your ITF-14 linear barcode is rotated on image file in 180 degrees, it can also be detected and recognized at fast speed. And the recognition result will include both barcode type and barcode data in array form.

Support Several Image Files in Three Forms

You are able to load Jpg/Jpeg, Gif, Png, Bmp, and Tiff/Tif image files into Visual Studio C# or VB.NET project and read ITF-14 bar codes. All these image files can be loaded as image string, image stream or bitmap of image.
