TopCreating PDF-417 barcode in VB.NET class example:
Imports OnBarcode.Barcode
Dim barcode As PDF417 = New PDF417

' Set the ProcessTilde property to true, if you want use the tilde character "~"
' to specify special characters in the input data. Default is false.

' 1) 1-byte character: ~0dd/~1dd/~2dd (character value from 000 ~ 255);
' ASCII character '~' is presented by ~126;Strings from "~256" to "~299" are unused
' modified to FS, GS, RS and US respectively.
' 2) 2-byte character (Unicode): ~6ddddd (character value from 00000 ~ 65535)
' Strings from "~665536" to "~699999" are unused

TopPDF-417 Error detection and correction (ECL) in VB.NET
Each PDF417 symbol contains at least two error correction codewords. The Error Correction codewords
provide capability for both error detection and correction.
The error correction level for a PDF417 symbol is selectable at the time of symbol creation. The VB.NET barcode software provides property "ECL". The following table shows the number of error correction codewords for each error correction level.

Create Compact (Truncated) PDF417 barcodes using Visual Basic .NET
Compact PDF417 is also named as Truncated PDF417. In the original AIM USA (1994) and AIM Europe (1994) PDF417 specifications,
the term Truncated PDF417 has been used in a technically synonymous manner.
Compact PDF417 may be used where space considerations are a primary concern and symbol damage is unlikely.
To create compact PDF417 using PDF417 generator VB.NET library, you need set property Truncated to true;

Common Asked Questions
What is PDF417 used for?
PDF417 is a high density, 2-dimensional stacked barcode symbology used in a variety of industries and applications, such as driver's license, airline boarding pass, transport, and inventory management.
Using VB.NET Barcode Generator library, you can quickly encode, create and print PDF417 barcode images in Visual Basic .NET class library, console, WinForms, WPF windows applications.
What is the maximum capacity of a PDF417?
The maximum number of characters encodable in a PDF417 barcode at lowest error correction level (0).
- Text Compaction mode: 1,850 characters
- Byte Compaction mode: 1,108 characters
- Numeric Compaction mode: 2,710 characters
PDF417.M_AUTO value to PDF417.setDataMode() method, the VB.NET barcode library will automatically
analyze the PDF417 encoding text characters and choose the right PDF417 data modes in Visual Basic .NET class library, console, WinForms, WPF windows applications.
What is the aspect ratio of a PDF417?
The aspect ratio of the printed PDF417 barcode shall be defined by two dimensions:
setX(): set the dimension of the narrowest bar and narrowest space. Using VB.NET barcode library, you can customize X value through methodPDF417.setX()setXtoYRatio(): the ratio of bar width vs bar height. Using VB.NET barcode library, you can customize it through methodPDF417.setXtoYRatio()
What is the difference between a PDF417 and a QR Code?
PDF417 and QR Code are both 2D or matrix barcode symbologies. PDF417 can be scannable even if up to 50% of it is damaged. QR Code can accept up to 30% damages.
VB.NET Barcode library supports both PDF417 and QR Code 2d barcode generations.
In VB.NET class, you can create and initiate a
In VB.NET class, you can create and initiate a
PDF417 object to generate PDF417 barcode images,
and initiate a QRCode object to draw QR Code images in Visual Basic .NET class library, console, WinForms, WPF windows applications.
