Hi there,

I've hijacked the Hot Prospect example's code scanner library to use the MetaDataObject to recognize a face and draw a mask over it. I'm so close, I'm successfully having the bounds get passed back, but there position seems a bit wonky. The X and Y coordinates seems flipped? The rectangle doesn't quite make it all the way through the whole range? Testing on an 5th gen iPad.

Any thoughts on how to get the rectangles to line up better? Thanks all in advanced.
