Generating Barcode PDF-417 in .NET is one of the functions in OnBarcode's
.NET Barcode Generators, which supports creating & printing PDF-417 and 30+ other linear & 2D bar codes for C#, VB.NET & ASP.NET applications.
OnBarcode develops several .NET Barcode Generation components for different .NET development environments:
.NET PDF 417 Generator encodes:
- all 128 characters of ASCII
- values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.

Barcode value to encode
PDF-417 Valid Data Char Set:
- Text Compaction mode permits all printable ASCII characters to be encoded, i.e. values
32 - 126 inclusive in accordance with ISO/IEC 646 (IRV), as well as selected control characters.
- Byte Compaction mode permits all 256 possible 8-bit byte values to be encoded. This
includes all ASCII characters value 0 to 127 inclusive and provides for international character set
support.
- Numeric Compaction mode permits efficient encoding of numeric data strings.
- Up to 811,800 different character sets or data interpretations.
- Various function codewords for control purposes.

PDF 417
Special |
Property: ProcessTilde
URL: PROCESS-TILDE
|
Type: bool
Default: true
|
Set the ProcessTilde property to true, if you want use the tilde character "~" to specify special characters in the input data. Default is true.
- 1-byte character: ~0dd/~1dd/~2dd (character value from 000 ~ 255); ASCII character '~' is presented by ~126
Strings from "~256" to "~299" are unused
- 2-byte character (Unicode): ~6ddddd (character value from 00000 ~ 65535)
Strings from "~665536" to "~699999" are unused
- Programming for reader initialisation: ~rp.
This should be located at the beginning of the encoding data, e.g. data = "~rpABCD1234".
- ECI: ~7dddddd (valid value of dddddd from 000000 to 999999)
