Direct Encoding Lower ASCII in PDF417 Native for Crystal Reports


I purchased the PDF417 Crystal Native Barcode Generator. 2D barcodes are completely new to me.

I know how to get the data for the barcode but just not clear on the configuration. I will attach the requirements documents.

Can I get help with the settings?

Operating System: Windows

Application: Crystal Reports

When encoding non-printable ASCII functions such as RS, GS, and EOT, IDAutomation recommends testing the result with the Barcode Decoder App because it reveals these characters in the result to verify proper encoding.

The attached documentation is the specifications for adding unprintable (lower decimal ASCII values*) function codes to the PDF417 barcode data, which will need to be directly encoded, as the PDF417 Native does not use ApplyTilde functionality.

*Use:
Chr(30) for RS
Chr(29) for GS
Chr(4) for EOT

For example, the following string in the DataToEncode:

"[)>" + RS + "01"+ GS + "0133626"+ GS + "840"+ GS + "002"+ GS + “123” + EOT

Is encoded with this string:

"[)>" + Chr(30) + "01"+ Chr(29) + "0133626"+ Chr(29) + "840"+ Chr(29) + "002"+ Chr(29) + “123” + Chr(4)
