Microsoft.Maui.Graphics.Skia DrawImage not working

Question

I'm trying to draw the lat/lng details onto a photo that the user has just taken.

I've managed to get an ICanvas working and the lat/lng drawn onto the canvas, but using DrawImage to get the photo taken onto the canvas is not working.

The result saved is just a blank jpg with the lat/lng printed, no photo.

Can anyone offer some insight as to why the IImage newImage is not being loaded onto the canvas

        if (MediaPicker.Default.IsCaptureSupported)
        {

            GetCurrentLocation(); // get lat long of current location

            FileResult photo = await MediaPicker.CapturePhotoAsync();

            if (photo != null)
            {
