License Dataset Scanner

1. Scan the back of the license

Use the large PDF417 barcode. The app does not save the photo or raw barcode.

Ready

Back of license Keep the barcode flat, sharp, and well lit.

Take Photo Choose Existing Image

Best option on iPhone: iPhone/iPad: Take Photo uses Apple’s native camera capture. Windows: Take Photo snapshots the webcam preview. Choose Existing Image always opens saved photos/files.

No license scanned yet.

Camera diagnostics: waiting.

Decoder: waiting for ZXing-C++ WASM.

Captured Photo — Barcode Crop

Drag a box tightly around the large PDF417 barcode, leaving a small border around it.

Photo ready

5-Test Barcode Diagnostic

Run five different decoding paths on the same captured photo. No raw license barcode data is included in the diagnostic report.

Image quality: waiting for photo.

#	Test	Status	Detail
1	Browser Native BarcodeDetector	Waiting	Uses the browser's own barcode engine if PDF417 is supported.
2	ZXing-C++ WASM — Original File	Waiting	Scans the untouched photo file.
3	ZXing-C++ WASM — Full Pixels	Waiting	Scans decoded full-resolution image pixels.
4	ZXing-C++ WASM — Selected Crop + Enhancements	Waiting	Scans your crop as color, grayscale, and thresholded black/white.
5	Legacy ZXing-JS — Selected Crop	Waiting	Uses the older independent JavaScript decoder on the crop.

Take a photo, adjust the crop around the PDF417 barcode, then run the five tests.

Tip: the selection should contain mostly the barcode, not the entire license. A small white border around the barcode helps the decoder.
