Worked example

The built-in QR sample decodes to Handy Orchard QR sample.

A blank image reports no code; decoded HTTP(S) text remains text and is never navigated to.

Method

Validate the image header and dimensions before decoding pixels. A dedicated worker runs the actual jsQR location, extraction and decoding pipeline.

The decoder tries normal and inverted pixels, returning text, version and corner coordinates when one code is recognized.

Limits

PNG/JPEG only, single code; no SVG, camera scan, barcode reading or guarantee that blurry/occluded/multiple codes will decode.

Processing can be cancelled by terminating its worker. Decoding does not verify a link’s safety, source identity or the truth of its content.
