Error: Cannot assign QImage to QUrl

I apologize for the mistake in the previous response. You are correct, you cannot directly assign a QImage to the source property of an Image component, as it expects a QUrl.

To resolve this issue, you need to convert the QImage to a format that can be used by the Image component. One way to do this is by converting the QImage to a QPixmap, and then converting the QPixmap to a data URL using the .toDataURL() method.

Here’s an updated code snippet:

Connections {
    target: someObject // Set your target object that emits imageReceived signal

    onImageReceived: {
        // Process the received QImage data
        var pixmap = Qt.createQmlObject('import QtQuick 2.0; Image { source: "" }', root, "DynamicSource");
        pixmap.source = image.toDataURL();
        
        // Pass the received image data to Image component
        imageComponent.source = pixmap;
    }
}

In this updated code, we convert the received QImage data to a data URL using .toDataURL() before assigning it to the source property of our dynamically created pixmap object. This allows us to correctly pass the image data to the Image component without any type conversion errors.

Once again, I apologize for any confusion caused by my previous incorrect explanation.
