VB.NET ITF-14 Barcode Recognition Overview
This VB.NET ITF-14 barcode reader control add-on is a professional SDK that is designed to help VB.NET developers (who have little or no knowledge in ITF-14 barcode recognition) integrate quick and high-quality ITF-14 barcode scanning and detecting features into their VB.NET imaging applications. ITF-14, a common linear barcode type, is often used to encode a Global Trade Item Number. Nowadays, people always tag product package with this ITF-14 barcode image.

.NET Image SDK also provides a multi-functional
ITF-14 barcode generator control which can be used to create ITF-14 barcode on image files and documents.
VB.NET ITF-14 Barcode Scanner Installation
The installation of this VB.NET ITF-14 barcode decoder control SDK is extremely easy. Users just need to integrate those ITF-14 barcode scanning dlls into their VB.NET project by adding reference. The only issue that we need to address here is the activation of evaluation license, which you can know more by viewing this
VB.NET Image SDK License tutorial page.
Apart from supporting ITF-14 barcode detecting and reading from document image file, this
.NET, VB.NET Barcode Reader SDK can be also used to scan and decode other numeric barcode types in VB.NET imaging applications, like
Interleaved 2 of 5,
ISBN and
ISSN.
VB.NET ITF-14 Barcode Recognition from Image
In this part, we will offer you a sample VB.NET example to illustrate the ITF-14 barcode recognition from image files. This RasterEdge.Imaging.Basic.dll library will allows you to open & decode target image file. Then this RasterEdge.Imaging.Barcode.Scanner.dll assembly offers APIs for you to detect and decode all the ITF-14 barcodes from target image file.
Public Shared FolderName As String = "c:/"
Private Sub button1_Click(sender As Object, e As EventArgs)
Dim fileName As String = FolderName & "SampleBarcode.tif"
Dim datas As String() = BarcodeScanner.Scan(fileName, BarcodeType.ITF14)
For Each data As String In datas
Debug.WriteLine(data)
Next
End Sub
VB.NET ITF-14 Barcode Scanning from PDF
If you want to decode ITF-14 barcode image from PDF file, besides above mentioned two dlls, you need to integrate another library (RasterEdge.Imaging.PDF.dll) into your VB.NET PDF processing application.
In the real application, the ITF-14 is often located in a small area of a large PDF page. Under this condition, in order to improve the ITF-14 barcode reading efficiency, you can just let the VB.NET barcode reader detect ITF-14 barcode in a relatively smaller area. As this VB.NET ITF-14 barcode reader SDK adopts the application of X & Y location, the scanning area can be easily defined.
Public Shared FolderName As String = "c:/"
Private Sub button1_Click(sender As Object, e As EventArgs)
Dim fileName As String = FolderName & "Sample.pdf"
Dim reImage As REImage = DirectCast(REFile.OpenDocumentFile(fileName, New PDFDecoder()).GetPage(0).ToImage(), REImage)
Dim datas As String() = BarcodeScanner.Scan(reImage, BarcodeType.ITF14)
For Each data As String In datas
Debug.WriteLine(data)
Next
End Sub
VB.NET ITF-14 Barcode Reading from Word
The function of detecting ITF-14 barcode from a specified area is also available in the VB.NET Word document barcode reading application.
Public Shared FolderName As String = "c:/"
Private Sub button1_Click(sender As Object, e As EventArgs)
Dim fileName As String = FolderName & "Sample.docx"
Dim reImage As REImage = DirectCast(REFile.OpenDocumentFile(fileName, New DOCXDecoder()).GetPage(0).ToImage(), REImage)
Dim datas As String() = BarcodeScanner.Scan(reImage, BarcodeType.ITF14)
For Each data As String In datas
Debug.WriteLine(data)
Next
End Sub
