Thanks for the input. It looks like this solves the problem without any performance issues.
So I will use the API to convert the map view with routing and zoom level into an image.
If I use Qt on Android in Android mobile application, Please let me know if I can render the same image back onto a QQuickwindow.

The rendered image needs to be of high resolution so that zooming in to lower detail(as saved in jpeg) should be possible in mobile app.

Thanks and Regards,

Qt Location does not provide an API for this, but it looks like it is possible by changing the render target of the QQuickWindow that the map is rendered in to an FBO and converting that to an image. See the documentation for
QQuickWindow::setRenderTarget() and QOpenGLFramebufferObject::toImage().
