I am working on a rails application that needs to send an piece of HL7 data encoded as PDF417 as JSON over API. The receiver of the barcode encoding will then insert the data into a word document with a PDF417 IDAutomation barcode font.
The problem I am running into is providing an encoding that the font likes.
I've used several encoders, Barby, https://github.com/asee/pdf417, https://github.com/asee/pdf417, which produce arrays of integers(codewords) via text compaction, binary compaction, etc, but all of these are different than what the IDAutomation font expects. Using their encoders it creates a list of 11 rows of numbers 324 chars each.
I seem to be missing a key piece of information here, but having trouble finding the explanation. I found a clue regarding getting the right error correction, row count, and column count values, but it still seems to be a big disconnect between what ID Automation font wants, and these ruby barcode encoders produce. (An array of binary, or an array of codewords)
For example with Barby: Binary:

Thanks in advance!
The ID Automation font is only going to "like" it's own proprietary encoding scheme, which appears to be using something similar to octal instead of the Barby binary or "tc" decimal. The three schemes all create different PDF417 barcodes with different number of rows and columns.
What you are running into is the stage gap between digitization and rendering. The digitization stage is responsible for turning data into the dots and spaces required for the specific symbology used (Code 128, PDF417, etc). The rendering stage is used to take the ones and zeros and turn those into ink or light up pixels.
You can't mix the two stages because the first stage creates the encoding in the format that the second stage needs.
I tried to convert the ID Automation encoding to binary from what I assumed was octal. It did not scan. The Barby binary encoding scanned like a champ.
