qr-filter-qml-plugin

qr-filter-qml-plugin allows you to work with QR codes via QML. Based on zxing-cpp. Currently only QR-code reading is availaible.

How to use

Plugin based on VideoOutput qml-feature - filters.

import Amber.QrFilter 1.0

VideoOutput {
    id: videoOutput
    filters: [ qrFilter ]
}

QrFilter {
    id: qrFilter
}

QrFilter is inherited from QAbstractVideoFilter, so all properties from QAbstractVideoFilter, e.g. active state can be used.

QrFilter {
    id: qrFilter
    active: camera.mode == "image" // enable filter only on image mode
}

Additionally QrFilter provide result property, where reading result is stored and explicit invokable method for clearing result clearResult.

property string passResult

VideoOutput {
    id: videoOutput
    filters: [ qrFilter ]
}

QrFilter {
    id: qrFilter
}

Button {
    visible: qrFilter.result.length !== 0 ? 1.0 : 0.0
    onClicked: {
        passResult = qrFilter.result
        qrFilter.clearResult()
    }
}
