📱 Scan QR Code

A focused demo for scanning QR codes from camera video or static images using the Dynamsoft Barcode Reader (JavaScript edition). Demonstrates QR-specific tuning and configuration.

Included files

• index.html — demo page (camera & image input).
• ReadQR.json — sample configuration/template used by the demo.

✨ Features

• Targeted QR decoding for improved performance
• Camera and static image input support
• Loadable JSON configuration for decoder settings

🔧 How it works

• The demo configures the scanner to prioritize QR decoding and applies ROI/resolution adjustments for common QR scenarios.
• Decoded payloads are displayed; configuration can be adjusted via ReadQR.json.

Quick start

Opening HTML files directly may not work as expected. Instead, run a local development server. Here’s a quick method using Visual Studio Code:

1. Install the Five Server extension from the VS Code Marketplace.

2. Right-click on index.html and select "Open with Five Server".

💡 Tips

• For small QR symbols increase camera resolution or reduce ROI.
• Good lighting and steady framing improves decode reliability.

📌 Notes

• Serve via localhost/HTTPS for camera permissions.
• Replace trial/demo license with a valid Dynamsoft license for extended use.
