## What it is
JAB Code (Just Another Bar Code) is a high-capacity 2D color bar code that encodes more data than traditional black-and-white barcodes. The repository provides a C library for reading and writing JAB codes, plus reader and writer sample applications.

## Use cases
- encode large amounts of data into a color 2D barcode
- generate JAB code images from files or text
- decode and read JAB code symbols from images
- embed a color barcode library in a C application
- try a high-capacity alternative to QR codes
- build a Windows DLL for barcode generation

## When to choose
- you need to encode more data than QR codes allow in a 2D symbol
- you want a C library for reading and writing color barcodes
- you need configurable error correction levels for barcode data

## When to avoid
- you need broad scanner/app compatibility like standard QR codes
- you need a pure black-and-white barcode symbology
- you need a managed-language (Java/Python) barcode library without C bindings

## Facets
- artifact type: library
- maturity: active
- function: image-processing, computer-vision, parser, cli
- domain: developer-tools, files
- platform: windows, cross-platform, cli, cpp
- tags: barcode, color-barcode, 2d-barcode, qr-code-alternative, jab-code, image-encoding, c11, linux
