Qr Code
This is a PHP library for generating machine-readable QR codes from text or data payloads. It functions as an image library that renders these codes into various formats while providing utilities to verify data accuracy and readability.
The project distinguishes itself by supporting branded QR code creation, allowing the embedding of custom logos and text labels. To ensure quality, it includes a validation tool that performs readability verification to confirm that generated codes are scan-ready before deployment.
The library covers a broad range of output and rendering capabilities, including multi-format export to PNG, SVG, WebP, and PDF. It manages data delivery through binary strings, data URIs, and filesystem files, and includes configurations for character encoding and image sharpness optimization.
