quick_rapid_barcode

A minimal 1D/2D barcode generator in C++ (CLI).

This project is assisted by AI and vibe coding tools.

Build

make

JPEG output (optional, requires libjpeg):

make USE_LIBJPEG=1

CUDA build (optional, requires nvcc toolchain):

make USE_CUDA=1

SSE build (optional, x86 with SSE2 support):

make USE_SSE=1

Usage

./qrb -t "abcdefg1234567" -s code128
./qrb -t "590123412345" -s ean13
./qrb -t "01234567890" -s upc
./qrb -t "HELLO-39" -s code39
./qrb -t "123456" -s itf
./qrb -t "HELLO" -s qr -o out.png -f png
./qrb -t "HELLO" -s qr -o out.png -f png --cuda
./qrb -t "HELLO" -s qr -o out.png -f png --sse

Common options

• -t <text> input text
• -s <symbology>: ean13 | upc | code128 | code39 | itf | qr
• -o <file> output image file
• -f <format>: ascii | png | jpg
• --scale <n> pixel scale (default 4)
• --height <n> 1D height in modules (default 60)
• --quiet <n> 1D quiet zone in modules (default 10)
• --cuda use CUDA for encode/render (requires make USE_CUDA=1)
• --sse use SSE for encode/render (requires make USE_SSE=1)

Notes

• QR encoder is version 1-L only (up to 17 bytes).
• Code39 supports: A-Z, 0-9, space, -, ..
• JPEG output requires libjpeg and make USE_LIBJPEG=1.
