[PySide] How to get QPixmap from QCamera

[henry.wede at yahoo.com]

Hello,I am trying to create a program so I can use a USB microscope/camera for alignment on a CNC router.  The image needs to have cross-hairs and other helpful geometry overlayed on top of the camera image.  I have spent a few hours looking at examples and trying to come up with a solution from the documentation.  
I think that I would like to have a QTimer that gets an image from the QCamera a couple times a second and then uses that in a QGraphicsScene.  Then I can control the Z ordering and easily add lines, circles, etc.  I have done some drawing in the QGraphicsScene before so I am comfortable with that part.  However, I cannot find a way to get the image from the QCamera object.  
Can anyone offer a suggestion?  I am out of my comfort zone with this one.
Thanks,Henry
