[Interest] QMLCamera image capture, but not write to disk?

[Jason H]

I want to capture an image but not have it written to the disk. Is there any way in QML to do this? 
The documentation says onImageCaptured(QImage preview) awill happen then onImageSaved(QString url) will be fired when writing is complete. I would like the first but not the second to ever happen. 

Thanks.
