QML-Change data in Image Details tab properties

neda

Hi,
I use Qt version 5.6.0 with qml from windows 8.1.
I want to set metadata for captured images in QML.
I've tried the following code, the program runs on desktop takes the picture and saves it.
After I open it up with Preview and check the metadata... and nothing special there (no Author key).

Camera {
                                id: camera
                                metaData.author: "neda"

I don't see an "author" property listed in "metaData" here: http://doc.qt.io/qt-5/qml-qtmultimedia-camera.html

I've never actually done this, so I'm not sure, but I think this might work after reading the documentation.

Camera { id: cam }

Button {
    onClicked: {
        cam.imageCapture.setMetadata("Author", "neda");
        cam.imageCapture.capture();
   } 
}

Thank you.
I see this link

I use this code but it does not work.

Camera {
                                id: camera
                                metaData.cameraModel: "lenovo"

Thank you.

I use this code but It does not work.

 imageCapture {
     onImageMetadataAvailable:{
        setMetadata(key,value)
        console.log("Image Metadata Callback : "+key+" = "+value)
        setMetadata("Title","neda")
    }

onClicked: {
camera.imageCapture.setMetadata(camera.metaData.author, "neda")
//or this code:
camera.imageCapture.setMetadata("Author", "neda")
//or this code:
camera.metaData.author="neda"

camera.imageCapture.capture()

Update: I also tried to do that using QImageWriter as follows:

QImage image("c:/1.jpg");
QImageWriter writer("c:/11.png", "png");
writer.setText("Author", "neda");
writer.write(image);

But, none of my tries gave me any success (change data in Image Details tab properties). Any idea?
