[SOLVED]Possible to transfer QML grabToImage result to C++?

[ozzieve]

Is there any way to transfer the image resulting from a grabToImage in QML to C++ please, rather than the saveToFile shown in the documentation?

itemId.grabToImage(function(result) {
                    result.saveToFile("webpage.png");
                });

Below is the closest thing I've found to a solution, but I was wondering if there is a more mainstream/supported method?

Thank you.

Kept searching and found a solution to my own question:
in MyClass.cpp:

void MyClass::getGrabbedImage(QObject* i)
{
    QQuickItemGrabResult *item = nullptr;
    item = qobject_cast<QQuickItemGrabResult*>(i);
    QImage qi(item->image());
...
}

...in MyClass.h:

Q_INVOKABLE void getGrabbedImage(QObject*);

..and in the .qml:

itemId.grabToImage(function(result) {myClass.getGrabbedImage(result);});
