[MacRuby-devel] MacRuby challenge

[Alan Skipp]

The only thing that I can think of which could account for the wrong positioning is the resolution of your webcam/isight. A resolution of 640x480 is assumed in the code, if your webcam is higher resolution then that could explain the discrepancy.

Try adding the following line (after initialising the AVCaptureSession).

session.sessionPreset = AVCaptureSessionPreset640x480

The effect is perhaps more like being pursued by a persistent tache, rather than wearing a tache. Those with more powerful hardware (or less inclination to move around in front of the camera) may have more convincing results.
