CardSnapshot Capacitor Plugin

Native snapshot capture for pixel-exact ID card export.

Installation (mobile app repo)

1. Add this plugin to your Capacitor app package.json:
   • "card-snapshot": "file:../plugins/card-snapshot"
2. Run npm install in the mobile app.
3. Sync Capacitor:
   • npx cap sync

API

CardSnapshot.captureRect({ x, y, width, height, scale })

Returns:

• base64 PNG
• mime
• width, height (pixels)

Notes

• The JS app uses window.devicePixelRatio as scale.
• Snapshot is taken from the root view; crop uses the DOM rect.
