PDF-417 Barcode Control Introduction in VB.NET

KA.Barcode Generator for .NET Suite allows developers to create and encode PDF-417, MacroPDF-417 barcodes and other linear & bi-dimensional barcode symbols in .NET development environments, such as Microsoft Visual Studio 2005/2008/2010. In addition, KeepAutomation provides complete barcoding tutorials for PDF-417 data encoding, size & image setting tutorials with detailed VB.NET sample code.

PDF-417 Barcode Introduction

PDF-417, also named as Portable Data File 417, PDF 417 & PDF417 Truncated, is a stacked barcode symbol used mainly in transport, inventory management and identification cards.

KeepAutomation supports the following PDF-417 data formats:

Auto: KeepAutomation's software will select proper data format according to input data
Text: each codeword represents one or two characters
Byte: each group of 5 codewords represents 6 bytes
Numeric: groups of up to 15 codewords represent as many as 44 decimal digits

Advanced PDF-417 Customization in VB.NET

PDF-417 Error Correction Level (ECL) Configuration

PDF-417 uses error correction codewords to detect and fix damaged symbols. Each symbol includes a minimum of two error correction codewords. You can select the correction level using the ECL property in VB.NET.

Supported Error Correction Levels

Level 0: 2 error correction codewords
Level 1: 4 error correction codewords
Level 2: 8 error correction codewords
Level 3: 16 error correction codewords
Level 4: 32 error correction codewords
Level 5: 64 error correction codewords
Level 6: 128 error correction codewords
Level 7: 256 error correction codewords
Level 8: 512 error correction codewords

How to apply PDF417 ECL settings in VB.NET?

Set the desired level via the ECL property

Create Compact (Truncated) PDF-417 Barcodes

Truncated PDF-417 (Compact PDF-417) reduces symbol size for space-limited applications. This format is recommended for environments where physical damage is unlikely.

Create a new PDF417 object in Visual Basic class.
Assign your data to the Data property.
Set Truncated = True to enable compact mode.
Generate the barcode image.

Create Macro PDF-417 Barcodes in VB.NET

Macro PDF-417 allows you to split large datasets across multiple PDF-417 symbols. You can use up to 99,999 linked symbols for extended data storage. This feature is ideal for large file transmission in WinForms/WPF applications.

Set Macro = True to enable Macro PDF-417 mode.
Assign a unique MacroFileIndex (shared by all linked symbols).
Define MacroSegmentCount (total number of symbols).
Set MacroSegmentIndex (sequence position, starting at 0).

Note: All symbols in the same Macro group must use the same MacroFileIndex for successful scanning and data reconstruction.

Frequently Asked Questions

What is the use of PDF417?

PDF417 is a dense, stacked 2D barcode format. It's applied in many scenarios, such as driver's licenses, travel documents, secure identification cards, airline boarding passes, transport, and inventory management.

What's the main difference between a PDF417 and a QR code?

These are two common 2D barcode formats. PDF417 can still be scanned if up to 50% of it is damaged. By contrast, Q but QR codes only up to 30%.

What's the highest storage capacity of a PDF417 barcode?

Under the lowest error correction:

Text: 1,850 characters
Bytes: 1,108 characters
Numerals: 2,710 characters

What determines the aspect ratio of a PDF417?

A printed PDF417's aspect ratio is based on two measurements:

X: The size of the smallest bar and smallest space.
Y: The height of each row.
