如何在js文件中使用qml相机？

Question

I want to capture images in new thread because this process freezes main GUI. How can I make new thread to use qml camera in Javascript to avoid freezing of main interface?

//main.qml MouseArea
{
    anchors.fill: parent
    onClicked: 
    myWorker.sendMessage("Capture Image")
}
WorkerScript
{
        id: myWorker
        source: "qrc:/images/threader.js"  
        onMessage:console.log("Captured") 
 }      //threader.js WorkerScript.onMessage=function(message) { 
        WorkerScript.sendMessage({'reply': camera.ImageCapture.Capture()}) }

QML is not really designed with the intention of working within more than one thread. The origional intention was that any threading should be handled by the layer existing in C++. Check this link for an example for capturing images in C++.
