QmlMobileScanner

QmlMobileScanner is a DEMO barcode & QR code scanner based on qzxing and zxing-cpp libraries to scan and generate barcodes, and zint to generate some extra formats.

Qt 6.8+, Qt Multimedia (with ffmpeg backend) and CMake are needed.
Qt 6 major and minor versions are full of API and build breakages, it's just not feasible for me to support a matrix of different versions or build systems, sorry.

Available backends:

• zxing-cpp / v3.0.2 + custom QML integration
• QZXing / v3.3.0 + Qt6 port + many patches
• zint / v2.16 + custom QML integration

Works on Android and iOS!

Works on Linux, macOS, Windows too!

Supported Formats (zint)

zint is a barcode encoding library supporting over 50 symbologies including Code 128, Data Matrix, USPS OneCode, EAN-128, UPC/EAN, ITF, QR Code, Code 16k, PDF417, MicroPDF417, LOGMARS, Maxicode, GS1 DataBar, Aztec, Composite Symbols and more.

Supported Formats (zxing-cpp)

zxing-cpp is an open-source, multi-format linear/matrix barcode image processing library implemented in C++.

| Linear / 1D barcodes | Matrix / 2D barcodes | | -------------------- | -------------------- | | UPC-A | QR Code | | UPC-E | Micro QR Code | | EAN-8 | rMQR Code | | EAN-13 | Aztec Code | | DataBar | Aztec Rune | | DataBar Expanded | Data Matrix | | DataBar Limited | PDF417 | | Code 39 | Compact PDF417 | | Code 93 | MicroPDF417 | | Code 128 (GS1) | MaxiCode (partial) | | Codabar | DX Film Edge | | ITF | |

Supported Formats (QZXing)

QZXing is a Qt/QML wrapper library for the ZXing barcode image processing library.

QZXing still works fine, but is considered deprecated
