CLI-QR-Refiner

A specialized tool for OpenClaw agents to capture and refine rough ASCII/Unicode QR code blocks from CLI terminal outputs into crystal-clear, scannable PNG images.

Features

• Block Recognition: Automatically interprets █ (full), ▀ (upper), and ▄ (lower) block characters.
• Pixel-Perfect Scaling: Renders vector-like precision to ensure zero scanning failures.
• Zero Dependencies: Built on Python 3 + PIL (pre-installed on most systems).
• Headless Optimized: Designed specifically for server-side environments where terminal displays are unreliable.

Dependencies

• Runtime: Python 3 (no external packages required — uses built-in PIL/Pillow)
