PDF417 Barcode Generator Lib for .NET in VB Class

• Create a new PDF417 object
• Enter encoding data to property Data
• Call method drawBarcode to print PDF417 barcode to a PNG image file

Dim barcode = New PDF417()
barcode.Data = "https://www.barcodelib.com"
barcode.drawBarcode("C://Output//vb-net-pdf417-demo-image.png")

• Enable property ProcessTilde to true to support ASCII control characters encoding in PDF417 barcode
• In property Data, you need convert each control character to its ASCII integer value in the following format: ~ddd. Here ddd is the ASCII value in 3 digits.

Dim barcode = New PDF417()
barcode.ProcessTilde = True
barcode.Data = "AB~013C-123-abc"
barcode.drawBarcode("C://Output//vb-net-pdf417-barcode-ascii-control-chars.png")

• Enter non-English text into property Data
• Enable property IsUnicodeData to True to encoding Unicode text in PDF417 2d barcode

Dim barcode = New PDF417()
barcode.Data = "你好"
barcode.IsUnicodeData = True
barcode.drawBarcode("C://Output//vb-net-pdf417-barcode-unicode-text.png")

You can easily print PDF417 barcode with specified image width and height in VB.NET application.

• Set property ImageWidth with the specified image width in pixcel
• Set property ImageHeight with the specified image height in pixcel

barcode.ImageWidth = 600;
barcode.ImageHeight = 120;

PDF-417 Error detection and correction (ECL) in VB.NET

barcode.ECL = PDF417ErrorCorrectionLevel.Level_3

Create Compact (Truncated) PDF417 barcodes using Visual Basic .NET

Compact PDF-417, also known as Truncated PDF-417, omits the right row indicators and some other elements to reduce the symbol size. This variant is suitable when space is limited and symbol damage is unlikely.

To generate a compact PDF-417 using the BarcodeLib VB.NET generator, set the Truncated property to True.

Dim barcode = New PDF417()
barcode.Data = "PDF-417"
barcode.Compact = True
barcode.drawBarcode("C://Output//vb-net-pdf417-compact-demo.png")

Create Macro PDF417 barcodes in VB.NET

Macro PDF-417 provides a mechanism to split a large data set across multiple PDF-417 symbols. This is similar to Structured Append in other symbologies and is useful when encoding large files or extensive datasets.

Up to 99,999 individual PDF-417 symbols can be used within a single Macro PDF-417 structure.

1. Enable PDF417 Macro mode by setting the MacroPDF417 property to True.
2. Assign a unique, consistent MFileID value to all symbols that belong to the same data set.
3. Specify the total number of symbols using MOptSegmentCount. The valid value is from 1 to 99999.
4. Set the current symbol's sequence index using MSegmentIndex. The first symbol should use index 0.

Dim barcode = New PDF417()
barcode.Data = "Macro PDF-417"
barcode.MacroPDF417 = True
'Each int must be in range [0, 899]
barcode.MFileID = New Integer() {100, 200}
'Valid range: 0 ~ 99998
barcode.MSegmentIndex = 0
'Valid: 1 ~ 99999
barcode.MOptSegmentCount = 3
barcode.drawBarcode("C://Output//vb-net-pdf417-macro-demo.png")

Note: All symbols sharing the same data message must use the same MFileID value. Ensure MSegmentIndex values are correctly ordered to allow proper reconstruction when scanning.

1. Add Barcodelib.Barcode.ASP.NET.dll to your web project.
2. Add Barcodelib.Barcode.ASP.NET.dll to the Toolbox.
3. Find the folder barcode in the trial package and copy files "pdf417.aspx", "pdf417.aspx" to your web project folder.
4. Drag PDF417ASPNET from the Toolbox and drop it on your web project. Then you will see a PDF417 barcode image.
5. Adjust the settings in the Properties Window or generate it with above free VB.NET code.

1. Add BarcodeLib.Barcode.WinForms.dll to your Windows Forms project.
2. Add BarcodeLib.Barcode.WinForms.dll to the Toolbox.
3. Drag PDF417WinForm to your windows form and you will see a PDF417 barcode image. Click the image and adjust its parameters in the Properties Window or you can create a PDF417 barcode with above VB free sample codes.
