How do you calculate the focusPointOfInterest (a CGPoint value between 0,0 and 1,1) for an given AVCaptureDevice?
I've been following the code samples from the latest WWDC but I really don't understand how to calculation is being made. Also, my application is sitting in landscape vs. portrait (as in the sample) ... so in addition to not understanding how things are being calculated, I'm not sure what adjustments I need to make in order to account for landscape orientation.
Any help would be appreciated.
Thanks - wg
