This particular C++ ZXing port is one of the most recent C++ versions of popular ZXing library using modern compilers. 5 | 6 | Thanks to SCodes you can start scanning barcodes in few steps. We used Qt 5.15.2 and Qt 6.3.0 to built wrapper and example applications, but it's compatible with older Qt versions as well. 7 | 8 | Implementation of same method for both Qt version does not seems possible([check why](#porting)). We have ported the SCodes wrapper to Qt6 by following the multimedia [changes](https://doc-snapshots.qt.io/qt6-6.3/qtmultimedia-changes-qt6.html). 9 | 10 | --- 11 | 12 | [![Somco Software](./assets/Group%201.png)](https://somcosoftware.com) 13 | 14 | [![Built with Qt](./assets/buildWithQt.png)](https://qt.io) 15 | 16 | --- 17 | 18 | ## Supported Formats 19 | 20 | There are plenty of supported formats and we constantly work on adding new. 21 | 22 | ## Supported 1D Formats 23 | 24 | | Format | Supports scanning | Supports generating 25 | | ---------------- | ------------------------ | ------------------- 26 | | UPC-A |

47 | 48 | 49 | # How to use wrapper? 50 | ![SCodes Scanner Preview](/assets/scanner.gif)![SCodes Generator Preview](/assets/generator.gif) 51 | 52 | ## Using 53 | 54 | Feel free to read ["How to scan barcodes in Qt Qml application" blog post](https://somcosoftware.com/en/blog/how-to-scan-barcodes-in-qt-qml-application) if you are interested in the details behind scanning mechanism. Also you can try out the QmlReaderExample in order to see how it is working. 55 | 56 | SCodes supports generating barcodes as well. It is covered in ["How to generate barcode in Qt Qml" application blog post](https://somcosoftware.com/en/blog/how-to-generate-barcode-in-qt-qml-application). Also you can try out the QmlGeneratorExample in order to see how it is working. 57 | 58 | Above blog posts contains step by step tutorial on how to do that for Qt5 version. For Qt6 ([see here](#porting)). 59 | 60 | ### qmake 61 | All you need to do is to follow these steps. 62 | 63 | 1. Add SCodes as submodule, by typing `git submodule add git@github.com:scytheStudio/SCodes.git` 64 | 2. Update submodule `git submodule update --recursive --init` (you can also put wrapper files to your project manually without adding submodule) 65 | 3. Add `include(scodes/src/SCodes.pri)` to your .pro file 66 | 4. If you want to use barcode reader functionality you need to register `SBarcodeFilter` class for Qt5 or `SBarcodeScanner` class for Qt6. For both version, separate them with if directive to register as we did in barcode reader example([how to register reader class](#register-reader)). As for barcode generator functionality you just need to register `SBarcodeGenerator` class([how to register generator class](#register-generator)). 67 | 5. Import SCodes in your Qml file `import com.scythestudio.scodes 1.0` 68 | 6. Import multimedia module `import QtMultimedia 5.15` for Qt5 or `import QtMultimedia` for Qt6. 69 | 7. If build fails, try to add `CONFIG += c++17` to your .pro file 70 | 8. You are done. Get inspired by [Qt5 QML Barcode Reader demo](https://github.com/scytheStudio/SCodes/blob/master/examples/QmlBarcodeReader/qml/Qt5ScannerPage.qml) or [Qt6 QML Barcode Reader demo](https://github.com/scytheStudio/SCodes/blob/master/examples/QmlBarcodeReader/qml/Qt6ScannerPage.qml) to test wrapper. 71 | 72 | ### CMake 73 | 74 | 1. Add SCodes as submodule, by typing `git submodule add git@gitlab.com:scythestudio/scodes.git` 75 | 2. Update submodule `git submodule update --recursive --init` (you can also put wrapper files to your project manually without adding submodule) 76 | 3. Add to your project SCodes library 77 | 78 | ```CMake 79 | add_subdirectory(SCodes) 80 | ``` 81 | 82 | 4. Link SCodes library to your library or executable. 83 | 84 | ```CMake 85 | target_link_libraries(${PROJECT_NAME} PUBLIC SCodes) 86 | ``` 87 | 88 | 5. Import SCodes in your Qml file 89 | 90 | ```qml 91 | import com.scythestudio.scodes 1.0 92 | ``` 93 | 94 | 6. You are done. Get inspired by [QML Barcode Reader demo](https://github.com/scytheStudio/SCodes/blob/master/examples/QmlBarcodeReader/qml/ScannerPage.qml) to test wrapper. 95 | 96 | 97 | ### How to do 98 | Registering the barcode reader classes with if directive: 99 | 100 | ```c++ 101 | #if QT_VERSION < QT_VERSION_CHECK(6, 0, 0) 102 | qmlRegisterType("com.scythestudio.scodes", 1, 0, "SBarcodeScanner"); 103 | #else 104 | qmlRegisterType("com.scythestudio.scodes", 1, 0, "SBarcodeScanner"); 105 | #endif 106 | ``` 107 | 108 | Registering the barcode generator class with associated enum: 109 | ```c++ 110 | qmlRegisterType("com.scythestudio.scodes", 1, 0, "SBarcodeGenerator"); 111 | qmlRegisterUncreatableMetaObject(SCodes::staticMetaObject, "com.scythestudio.scodes", 1, 0, "SCodes", "Error: only enums"); 112 | ``` 113 | 114 | 115 | ### Implementation details in Qt6 116 | 117 | Qt's multimedia library has major changes. The most importants are, changes in QML `VideoOutput`, absence of `QVideoFilterRunnable` and `QAbstractVideoFilter` classes in Qt6. 118 | 119 | SCodes library is using `SBarcodeFilter` class for Qt5 and `SBarcodesScanner` class for Qt6 version. 120 | 121 | If you want to read more about implementation details of the library in Qt6 read the document: [Implementation Details in Qt6](https://github.com/scytheStudio/SCodes/blob/master/doc/detailsQt6.md) 122 | 123 | 124 | ### Trying various formats 125 | `SBarcodeFilter` is a class that you need to use for scanning case. By default it scans only specific basic formats of code (Code 39, Code 93, Code 128, QR Code and DataMatrix.). 126 | The goal of that is to limit number of possible formats and improve performance. 127 | 128 | To specify formats that should be accepted by the `SBarcodeFilter` instance, you need to set it's `format` property accordingly. This property allows setting multiple enum values as it's for flags. Add the following to your `SBarcodeFilter` item in Qml code: 129 | ```qml 130 | Component.onCompleted: { 131 | barcodeFilter.format = SCodes.OneDCodes 132 | } 133 | ``` 134 | See the enumeration values that represent supported formats in [SBarcodeFormat.h](https://github.com/scytheStudio/SCodes/blob/master/src/SBarcodeFormat.h) 135 | To accept all supported formats use `SCodes.Any`. 136 | 137 | ## Note 138 | 139 | Both build systems have their examples located in same directory. All you need to do is to just open proper file(CMakeLists.txt or *.pro file) for different build system to be used. 140 | 141 | 142 | ### The examples tested on below kits: 143 | 144 | #### Qt5.15.2 or less, 145 | 146 | | PROJECT | BUILD SYSTEM | WINDOWS-MinGW | WINDOWS-MSVC | LINUX-GCC | ANDROID | 147 | | ------ | ------ | ------ | ------ | ------ | ------ | 148 | | QmlBarcodeReader | qmake |

If you want to implement barcode reader functionality for both version you need to create two separate QML file too(that's because of QML VideoOutput changes in multimedia module of Qt6). Check our [QmlBarcodeReader example](https://github.com/scytheStudio/SCodes/tree/master/examples/QmlBarcodeReader) for more details. 3 | 4 | `SBarcodeFilter.cpp` and `SBarcodesScanner.cpp` files included/excluded according to the Qt version in the [SCodes CMakeLists file](https://github.com/scytheStudio/SCodes/blob/master/src/CMakeLists.txt). The idea of excluding the related class according to Qt version is prevent to get error from not existing libraries when you compile the project for Qt6(e.g. QVideoFilterRunnable, QAbstractVideoFilter). Likewise in Qt5 for QVideoSink. 5 | 6 | SBarcodeScanner class is inherited from QVideoSink class. It's initiated in 2 phases: First, the constructor sets up the connections to processing threads. Then, after QmlEngine sets up properties, `forwardVideoSink` and `camera`, a `componentComplete()` function is called that instantiates a default `QCamera` if none is set. 7 | 8 | This allows to set camera object in QML: 9 | ```qml 10 | SBarcodeScanner { 11 | ... 12 | camera: Camera { 13 | ... 14 | } 15 | } 16 | 17 | ``` 18 | 19 | Also, in the constructor, `Worker` object that dependent on scanner variable passed to workerThread instance. So, we can access to resources of the scanner object. 20 | ```c++ 21 | worker->moveToThread(&workerThread); 22 | ``` 23 | `VideoOutput` has a `forwardVideoSink` property in Qt6 which allows to pass the videoframes further to a `VideoOutput` sink or some other process. 24 | 25 | To handle the frames `QVideoSink::videoFrameChanged` signal connected to `SBarcodeScanner::handleFrameCaptured` slot. 26 | As soon as new frame has came to the handle function; 27 | ```c++ 28 | emit process(QImage &img); 29 | ``` 30 | signal emitted and `imageProcess` function started to run in worker thread. 31 | Also, frame passed to m_videoSink in order to show the frames on the screen. 32 | ```c++ 33 | m_videoSink->setVideoFrame(frame); 34 | ``` 35 | -------------------------------------------------------------------------------- /examples/QmlBarcodeGenerator/.gitignore: -------------------------------------------------------------------------------- 1 | *.pro.user 2 | *.pro.user* 3 | build-* 4 | *DS_Store 5 | -------------------------------------------------------------------------------- /examples/QmlBarcodeGenerator/CMakeLists.txt: -------------------------------------------------------------------------------- 1 | cmake_minimum_required(VERSION 3.16.3) 2 | 3 | project(QmlBarcodeGenerator LANGUAGES CXX) 4 | 5 | set(CMAKE_INCLUDE_CURRENT_DIR ON) 6 | 7 | set(CMAKE_AUTOMOC ON) 8 | set(CMAKE_AUTORCC ON) 9 | 10 | set(CMAKE_CXX_STANDARD 17) 11 | set(CMAKE_CXX_STANDARD_REQUIRED ON) 12 | 13 | #Check this file for any *_DIR variable definitions and other 14 | include("cmake/Locations.cmake") 15 | 16 | if(Qt${QT_VERSION_MAJOR} STREQUAL Qt5) 17 | qt5_add_resources(RSCS qml.qrc) 18 | else() 19 | qt_add_resources(RSCS qml.qrc) 20 | endif() 21 | 22 | add_subdirectory(${LIB_DIR} ${CMAKE_BINARY_DIR}/SCodes) 23 | 24 | if(ANDROID) 25 | 26 | if(Qt${QT_VERSION_MAJOR} STREQUAL Qt5) 27 | 28 | set(ANDROID_MIN_SDK_VERSION 21) 29 | set(ANDROID_ABI "armeabi-v7a") 30 | set(QT_ANDROID_PACKAGE_SOURCE_DIR ${PROJECT_SOURCE_DIR}/android) 31 | 32 | file(GLOB_RECURSE ANDROID_SOURCES 33 | ${QT_ANDROID_PACKAGE_SOURCE_DIR}/AndroidManifest.xml 34 | ${QT_ANDROID_PACKAGE_SOURCE_DIR}/build.gradle 35 | ${QT_ANDROID_PACKAGE_SOURCE_DIR}/gradle/wrapper/gradle-wrapper.jar 36 | ${QT_ANDROID_PACKAGE_SOURCE_DIR}/gradle/wrapper/gradle-wrapper.properties 37 | ${QT_ANDROID_PACKAGE_SOURCE_DIR}/gradlew 38 | ${QT_ANDROID_PACKAGE_SOURCE_DIR}/res/values/libs.xml 39 | ) 40 | add_library(${PROJECT_NAME} SHARED main.cpp ${RSCS} ${ANDROID_SOURCES}) 41 | 42 | else() 43 | 44 | qt_add_executable(${PROJECT_NAME} MANUAL_FINALIZATION main.cpp ${RSCS}) 45 | 46 | set_target_properties(${PROJECT_NAME} PROPERTIES 47 | QT_ANDROID_PACKAGE_SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/android" 48 | ) 49 | 50 | endif() 51 | 52 | else() 53 | 54 | add_executable(${PROJECT_NAME} main.cpp ${RSCS} 55 | ColorController.h ColorController.cpp) 56 | 57 | endif() 58 | 59 | target_link_libraries(${PROJECT_NAME} PRIVATE ${REQUIRED_QT_LIBS} SCodes) 60 | 61 | 62 | if(QT_VERSION_MAJOR EQUAL 6) 63 | qt_import_qml_plugins(${PROJECT_NAME}) 64 | qt_finalize_executable(${PROJECT_NAME}) 65 | qt_finalize_project(${PROJECT_NAME}) 66 | endif() 67 | -------------------------------------------------------------------------------- /examples/QmlBarcodeGenerator/ColorController.cpp: -------------------------------------------------------------------------------- 1 | #include "ColorController.h" 2 | 3 | ColorController::ColorController(QObject *parent) 4 | : QObject{parent} 5 | {} 6 | 7 | bool ColorController::checkColor(const QString &color) 8 | { 9 | return QColor(color).isValid();
