Bacon Themed QRCodes for Hungry Devices
summary
Provides an npm library that generates QR codes and renders them on server or client using canvas, with an API to underlay images and force scan-safe pixels. Claims a usable capacity of 1.2 k and shows bacon-backed QR codes that still scan after converting RGB to YUV and lowering luminosity with HDTV 709 coefficients. Exposes a pixel iterator in canvas util and offers effects and thresholds; notes node canvas can fail without the right cairo so image extraction may break.
