qrcode-ai-scanner 0.8.0

QR decoding + scannability scoring for artistic, AI-generated, and photo-captured QR codes — Rust core via PyO3.

qrcode-ai-scanner (Python)

QR decoding + scannability scoring for artistic / AI-generated / photo-captured QR codes — the Rust qrcode-ai-scanner engine, via PyO3. Same versioned ScanReport contract as the Rust, Node and WASM surfaces.

import qrcode_ai_scanner as qr

with open("image.png", "rb") as f:
    report = qr.scan(f.read(), profile="full")   # "full" | "fast" | "frame"

if report["detections"]:
    d = report["detections"][0]
    print(d["content"]["text"])
    print(report["score"]["value"], report["score"]["grade"])  # 0-100 + ISO band
    print(report["hints"])                                      # machine-actionable

• scan(image: bytes, profile="full", max_dimension=None, max_pixels=None, budget_ms=None) -> dict — decode encoded bytes (PNG/JPEG/WebP/GIF).
• scan_frame(rgba: bytes, width: int, height: int, profile="frame", max_dimension=None, max_pixels=None, budget_ms=None) -> dict — raw RGBA frame, no image-format roundtrip.
• Optional kwargs: max_dimension / max_pixels cap inputs BEFORE any pixel work (defaults 10000 px / 64 MP — lower them for untrusted uploads); budget_ms bounds the scan wall-clock (0 = unbounded — leave unset for strictly reproducible reports).
• "No QR found" returns a dict with empty detections; ValueError is raised only for invalid input.

The returned dict is the same ScanReport documented in the spec.
